STATE CORPORATION COMMISSION
CASE NO. PUR-2023-00069
Ex Parte: In the matter of revising
the Commission's Regulations Governing
Interconnection of Small Electrical Generators
and Storage
ORDER ADOPTING REGULATIONS
On May 8, 2009, the State Corporation Commission (Commission) adopted Regulations Governing Interconnection of Small Electrical Generators, 20VAC5-314-10 et seq. (Interconnection Regulations) in Case No. PUE-2008-00004.1 The Commission initiated that rulemaking in accordance with Code § 56-578 C, which provides, in part:
The Commission shall establish interconnection standards to ensure transmission and distribution safety and reliability, which standards shall not be inconsistent with nationally recognized standards acceptable to the Commission. In adopting standards pursuant to this subsection, the Commission shall seek to prevent barriers to new technology and shall not make compliance unduly burdensome and expensive.
On July 29, 2020, in Case No. PUR-2018-00107, the Commission revised the Interconnection Regulations.2
On March 3, 2023, in Case No. PUR-2022-00073 - a docket initiated to explore interconnection issues related to utility distribution energy resources (DER) - the Commission determined it would be appropriate to initiate a rulemaking proceeding to examine potential changes to certain topics in the Interconnection Regulations.3
As a result, on May 2, 2023, the Commission issued an Order Initiating Rulemaking Proceeding in the present docket to determine whether the Commission's Interconnection Regulations should be revised. As part of its Order Initiating Rulemaking Proceeding, the Commission directed the Commission's Staff (Staff) to: (i) solicit comments from, and to schedule a meeting or meetings (as necessary) with, stakeholders and persons having an interest in the Commission's Interconnection Regulations and the interconnection of small electrical generators and storage in the Commonwealth of Virginia; (ii) consider whether amendments to the Interconnection Regulations on the topics addressed in Case No. PUR-2022-00073 are needed;4 (iii) develop, with appropriate input from stakeholders and interested persons, a proposal for any revisions, if necessary, to the current Interconnection Regulations; and (iv) prepare and file a report (Report) on its findings and recommendations in this proceeding.
On August 7, 2024, the Commission issued an Order in Case No. PUR-2022-00073 further directing Staff to consider as part of the present docket: (i) updating Schedules 7-9 in 20VAC5-314-170 to include a field specifying a completion date for each study; and (ii) implementing a requirement for utilities to notify developers of any missed study deadlines and provide a new expected deadline.5 The Commission also directed Staff to propose minimum filing requirements for a Technical Interconnection and Interoperability Requirements (TIIR) document related to the Institute of Electrical and Electronics Engineers (IEEE) Standard 1547.6
On January 21, 2025, Staff filed its Report. In its Report, Staff noted that in accordance with the Commission's directive, Staff solicited comments from interested persons regarding the topics addressed in PUR-2022-00073.7 Staff received written comments from Appalachian Power Company (APCo); Appalachian Voices; Dominion Energy Virginia (Dominion); East Point Energy; Kentucky Utilities/Old Dominion Power; Virginia Distributed Solar Alliance; and the Virginia Electric Cooperatives (Cooperatives).8 Staff also received joint comments from the Coalition for Community Solar Access (CCSA), the Solar Energy Industries Association, and the Chesapeake Solar and Storage Association. Staff stated in its Report that it convened working group meetings with interested participants on April 18, 2024, to discuss the comments received and to determine whether amendments to the Interconnection Regulations were necessary, and on May 21, 2024, to discuss cybersecurity. Sixty stakeholders attended the April 18, 2024 meeting, and 30 stakeholders were in attendance at the May 21, 2024 meeting.9 Based on the input received from the working group participants and commenters, Staff prepared proposed revisions to the Interconnection Regulations (Proposed Rules).
On April 15, 2025, the Commission issued an Order for Notice and Comment in this docket, which: (i) found that the Staff's Proposed Rules should be considered for adoption; (ii) directed that a copy of the Proposed Rules should be sent to the Registrar of Regulations for publication in the Virginia Register of Regulations; (iii) provided any interested person an opportunity to comment on, propose modifications or supplements to, or request a hearing on the Proposed Rules; (iv) and directed Staff to file a response to any comments, proposals, or requests for hearing submitted to the Commission on the Proposed Rules (Staff Response or Response).
Written comments were received from APCo (APCo Comments), Appalachian Voices (Appalachian Voices Comments), CCSA (CCSA Comments), Collaborative Utility Solutions (CUS Comments), Dominion (Dominion Comments), and the Cooperatives (Cooperatives Comments). No requests for a hearing were received. Staff filed its Response on July 16, 2025.
NOW THE COMMISSION, upon consideration of this matter, is of the opinion and finds that the revised regulations attached hereto as Appendix A should be adopted as final rules, as discussed herein. In developing these revised regulations, we have reviewed the Proposed Rules and considered and weighed all arguments and comments presented in this proceeding in support of each participant's requests.
Material Modifications
The Interconnection Regulations discuss the types of changes that are considered material modifications to an interconnection request.10 Several revisions to this section were included in the Proposed Rules.
First, regarding the downsizing of an interconnection request, we find as follows:
A one-time change reducing the maximum generating capacity of a facility by up to 75% will not be considered a material modification;11
This one-time downsizing change will not be considered a material modification if it occurs at a point after the Feasibility Study, but before execution of the System Impact Study Agreement;12
If a developer elects to downsize, the Feasibility Study timeline should reset, providing utilities a 30-day window to complete a new study of the downsized project;13 and
For projects that proceed under a combined study agreement, a one-time downsizing of up to 10% will not be deemed a material modification.14
The Proposed Rules also amend when a change in the point of interconnection (POI) constitutes a material modification. Under the Proposed Rules, a change in POI to a new location constitutes a material modification, unless the new POI is within the same protection zone as the original location and the change in POI is agreeable to the utility. We find the proposed language on POI, including the addition of language that POI changes must be agreeable to the utility in order to be deemed non-material, to be reasonable.15 We concur with Staff that this language provides "necessary flexibility for utility discretion" and that concerns related to a perceived abuse of discretion may be addressed through the Interconnection Regulation's existing dispute resolution process.16
Next, the Interconnection Regulations currently state that any change in the direct current (DC) system configuration to include additional equipment that impacts the maximum generating capacity, daily production profile, or the proposed alternating current (AC) configuration of a facility or energy storage system constitutes a material modification.17 Dominion and Staff support leaving the current language unchanged at this time and recommend establishing a separate docket dedicated to addressing energy storage-related issues.18 In contrast, CCSA and Appalachian Voices oppose the existing restriction in 20VAC5-314-39 C that prevents changes to a facility's "daily production profile," arguing that this language unnecessarily precludes the addition of DC-coupled storage, even when AC export limits are unchanged.19 Appalachian Voices claims limiting energy storage to systems that included such storage in their original interconnection request is impractical, especially considering significant interconnection backlogs and the growing deployment of solar-plus-storage systems, and CCSA emphasizes the system benefits of expanded energy storage deployment.20
We concur with CCSA and Appalachian Voices that greater flexibility for adding storage without triggering a material modification is appropriate for the reasons listed above. As such, we find that the addition of DC-coupled storage, when AC export limits are unchanged, shall not be considered a material modification.21
Next, the Interconnection Regulations currently provide that a change of transformer connections or grounding, or a change to certified inverters with different specifications or different inverter control specifications than originally proposed, represents a material modification to an interconnection request.22 CCSA proposes allowing a one-time equipment modification during the interconnection process, specifically at the stage when the Small Generator Interconnection Agreement (SGIA) is executed.23 CCSA notes that the time between submission of an initial interconnection application and the execution of an SGIA can span several years, during which time inverter models initially selected may be discontinued, increase significantly in cost, or become technologically outdated.24 Given that transformer design is closely tied to inverter selection, CCSA asserts that a change in inverter model will often require updates to transformer specifications as well.25 Conversely, Dominion and Staff recommend retaining the existing language regarding certified inverters as well as transformer connections and grounding.26
We concur with CCSA that given the continually evolving nature of inverter technology and the often significant time between submission of an initial interconnection request and the execution of an SGIA, a one-time modification in inverter and/or transformer design or specification, without such change being considered a material modification, is reasonable.27
Dispute Resolution Process
With regard to the dispute resolution process, we find as follows:
The proposal in the Proposed Rules to toll the specified time periods for an interconnection request during the period in which parties are engaged in a dispute resolution process is reasonable and is adopted;28
Establishing an ombudsperson to participate in the dispute resolution process is unnecessary at this time, as the Interconnection Regulations already provide multiple procedures, including both informal and formal options, for the resolution of disputes;29
If a dispute remains unresolved after 30 business days, the utility shall provide written notice to Staff.30
DER Definitions
There is no disagreement amongst participants concerning the definitions for DERs and Energy Storage Systems included in the Proposed Rules. As such, those definitions are adopted.31
Cybersecurity Standards
Dominion, the Cooperatives, Appalachian Voices, APCo, and Staff all provided input on cybersecurity requirements for DER interconnections.32 There was general alignment between the commenters on the need for minimum cybersecurity standards, though differences on scope, implementation, and flexibility existed.33 We find that, as set forth in the Proposed Rules, each utility shall establish its own utility-specific minimum cybersecurity standards that are based on, and are not in conflict with, nationally recognized guidelines, including but not limited to: (i) the IEEE Standard 1547.3 - Guide for Cybersecurity of Distributed Energy Resources Interconnected with Electric Power Systems (2023), and (ii) the National Association of Regulatory Utility Commissioners' Cybersecurity Baselines for Electric Distribution Systems and DERs.34 We concur with Dominion that these national standards are appropriate sources for minimum cybersecurity requirements for interconnections at the distribution level, and that utilities should retain flexibility to implement more stringent standards if necessary.35
We decline to change the language in the Proposed Rules to "based on, and not to materially exceed, nationally recognized guidelines," as suggested by Appalachian Voices.36 We concur with Staff that the amendments to the Interconnection Regulations should not establish a ceiling that prevents a utility from developing effective security capabilities or hampers its ability to manage emerging cyber threats and vulnerabilities.37 However, we do direct utilities to implement standards, to the extent possible, that are not unduly burdensome or costly for interconnection customers.38
Finally, APCo asserts that developing and coordinating standards will take time and effort.39 We find that utilities shall, within 18 months of the date of this Order, develop cybersecurity standards, including an associated implementation plan with milestones for interconnection customers to achieve compliance with the standards.40
Updates to Schedules 7-9
The Proposed Rules include revisions to subsections C through E of 20VAC5-314-70 to require utilities to: (i) notify developers no later than five business days before a deadline if the utility anticipates missing the deadline; and (ii) provide the new expected completion date. Correspondingly, proposed changes to Schedules 7-9 in 20VAC5-314-170 added a completion date for each study. Dominion, Appalachian Voices, CCSA, and Staff all generally support these proposed revisions.41 Dominion, however, recommends amending the proposed language in subsections C through E of 20VAC5-314-70 to require utilities to "provide the new expected completion date to the extent the information is available."42 We adopt the revisions to 20VAC5-314-70 and 20VAC5-314-170, with Dominion's proposed change.
Appalachian Voices and CCSA support the inclusion of deadlines, but suggest that deadlines without enforcement are insufficient.43 Appalachian Voices recommends financial penalties for missed interconnection study deadlines and CCSA recommends the adoption of a timeline enforcement mechanism (TEM) where utility performance is assessed based on the average time taken to process interconnection applications.44 We decline to establish monetary penalties or establish a TEM at this time as part of the Interconnection Regulations.45 However, we acknowledge the concerns raised by CCSA and Appalachian Voices. We note that certain utilities (collectively, "Phase I and Phase II Utilities) must file biennial reviews pursuant to Code § 56-585.1 A, which include a review of the utility's generating plant performance, customer service, and operating efficiency when setting the utility's rate of return on equity.46 As such, parties are invited to bring evidence as to a Phase I or Phase II Utility's performance in this regard in a future biennial review proceeding.
TIIR
Participants generally support the creation of a TIIR document, though they differ on the scope of the document and the process for approving and updating the document.47 With regard to TIIR requirements, we find as follows:
As supported by Dominion, the Cooperatives, CCSA and Staff, we find that every investor-owned electric utility and electric cooperative in the Commonwealth shall develop a utility-specific TIIR document that outlines key interconnection settings and protocols;48
Each TIIR shall include, at a minimum: (i) voltage and frequency trip settings; (ii) frequency drop settings; (iii) activated reactive power control function and settings; (iv) voltage-active power mode activation and settings; (v) enter service settings; and (vi) communication protocols and port requirements.49 A range of acceptable values may be included in a utility's TIIR document to address differences in location;50
Each investor-owned electric utility and electric cooperative in the Commonwealth must submit a TIIR document to the Commission for approval,51 and, once approved, each shall make its TIIR document publicly available on its website;52
Any subsequent changes to TIIR documents shall be submitted to Staff for administrative review. Staff shall review the proposed changes administratively; however, if any proposed change appears to be material, Staff shall subsequently recommend that a formal approval process, including an opportunity for comments from interested persons, be conducted;53 and
Each investor-owned electric utility and electric cooperative must file their initial TIIR document within nine (9) months of the date of this Order. These TIIR documents shall be filed in the present docket.
Miscellaneous
Several additional matters were raised by commenters in this case.54 While we have reviewed and considered the arguments and requests concerning these matters, we do not find that the Interconnection Regulations should be further amended at this time beyond the changes discussed above and included in Appendix A.
Accordingly, IT IS ORDERED THAT:
(1) The Regulations Governing Interconnection of Small Electrical Generators and Storage, as shown in Appendix A to this Order, are hereby adopted and are effective as of September 1, 2026.
(2) The Commission's Office of General Counsel forthwith shall send a copy of this Final Order and the attached regulations to the Registrar of Regulations for publication in the Virginia Register of Regulations.
(3) A copy of this Final Order and the attached regulations forthwith shall be posted on the website of the Division of Public Utility Regulation. In addition, the Staff of the Division of Public Utility Regulation shall email a copy of the Final Order and attached regulations to all persons and entities who participated in the workgroup meetings held to receive input on the regulations or filed comments in this docket.
(4) The Clerk of the Commission hereby is directed to serve a copy of the attached regulations on every investor-owned electric utility and electric cooperative in the Commonwealth, who shall forthwith thereafter notify all their interconnection customers.
(5) This case is continued.
A COPY hereof shall be sent electronically by the Clerk of the Commission to all persons on the official Service List in this matter and to all persons on the official Service List in Case No. PUR-2022-00073. The Service Lists are available from the Clerk of the Commission.

11See, e.g., Appalachian Voices Comments at 4 (stating, "Appalachian Voices supports Staff’s revision to the material modification section to allow a developer to make a one-time downsizing change of up to 75%. . . ."); Dominion Comments at 3 (stating, Dominion "does not oppose Staff’s proposed revision to the material modification section of the Interconnection Regulations to allow a developer to make a one-time downsizing change of up to 75%"); Cooperatives Comments at 7 (stating, "the Cooperatives believe that this will ultimately be helpful; however, a 75% reduction in a project’s size while maintaining its queue position may ultimately create more problems for other projects and the solar industry"); and CCSA Comments at 2-3 (stating, "This rule change offers essential flexibility to developers as they respond to project site constraints or unanticipated distribution system upgrade costs during the pre-development study process"); Staff Response at 6 (stating, "Staff maintains its position that the one-time downsizing cap should be up to 75%"). Though certain commenters suggest: (i) there should be no limit on the percentage a project can downsize; or (ii) an alternative modification option through a "connect and manage" arrangement should also be approved, we decline to adopt such recommendations at this time. See, e.g., CCSA Comments at 3; Appalachian Voices Comments at 4-9.
12See, e.g., Dominion Comments at 3-4 (stating, Dominion "respectfully requests that if a developer makes a one-time downsizing change of up to 75% that the change occur prior to the developer requesting the System Impact Study Agreement and after the Feasibility Study has been completed"); Cooperatives Comments at 7 (stating, "Furthermore, the Cooperatives agree with [Dominion] that any change be timed to precede the System Impact Study and follow the Feasibility Study"); CCSA Comments at 3 (stating, "CCSA recommends moving the downsizing decision point from the Facilities Study Agreement to the System Impact Study Agreement"); Staff Comments at 6-7 (stating, "Staff supports shifting the decision point for a developer to make a one-time downsizing change from after the System Impact Study, as was originally recommended in the Staff Report, to a point after the Feasibility Study but before execution of the System Impact Study Agreement"). This change would impact the situations where a Project B is studied in parallel with Project A. The Project B developer shall not be required to sign the System Impact Study Agreement first, thereby losing its chance to downsize. See Staff Response at 7.
13See, e.g., Dominion Comments at 4; Cooperatives Comments at 7; Staff Response at 7.
14See, e.g., Dominion Comments at 3-5; Cooperatives Comments at 7; Staff Response at 7-8. The existing language in the Interconnection Regulations already permits such a reduction. See 20VAC5-314-39.

19See, e.g., CCSA Comments at 4-5; Appalachian Voices Comments at 9-10.
20See, e.g., Appalachian Voices Comments at 9-10; CCSA Comments at 4-5.
21To implement this amendment, we find that the "daily production profile" language in the Interconnection Regulations shall be removed. The decision to add storage, without triggering a material modification, would need to occur at a point after the Feasibility Study, but before execution of the System Impact Study Agreement. Should a developer wish to reduce the size of a facility in conjunction with the addition of energy storage, such change, in order not to be considered a material modification, must comply with the limitations on downsizing discussed herein.
22See 20VAC5-314-39 B 4 and 5.
23See CCSA Comments at 5-6. As part of this change, CCSA recommends striking 20VAC5-314-39 B 4 and 5. See id. at 5.
26See, e.g., Dominion Comments at 6; Staff Response at 11.
27Such change must involve Underwriters Laboratories 1741 certified inverters and must occur before the SGIA is executed. Changes from certified to uncertified inverter models shall continue to be considered a material modification.
28No commenter opposes the proposal. See, e.g., Dominion Comments at 6-7; Cooperatives Comments at 8; CCSA Comments at 7-8; Appalachian Voices Comments at 11; Staff Response at 12-13.
29See, e.g., CCSA Comments at 7-8 (stating, "CCSA continues to encourage the Commission to adopt a more robust dispute resolution process that includes the establishment of a Distributed Generation Ombudsperson within the Commission [which] would create a single point of contact through which customers can obtain information and seek advice on the proper steps to take to resolve issues and can also fulfill a role of mediating disputes between parties. . . ."); Dominion Comments at 6 (stating, "Staff concludes that an ombudsperson is unnecessary at this time as the existing rules allow parties to seek resolution through the Division of Public Utility Regulation or through a dispute resolution service. The Company agrees."); Staff Response at 13 (stating, "Staff maintains its position that establishing an ombudsperson may be premature and is not necessary at this time").
30See, e.g., Dominion Comments at 6 (stating, "the notification process after 20 business days will result in additional reporting requirements for the Company, prolong the dispute resolution process, and take Staff’s time to resolve issues for which the regulations already provide clear guidelines for utility and the Interconnection Customer to use in pursuit of a resolution"); Staff Response at 13 ("Staff also continues to support the requirement for utilities to provide written notification to Staff if a dispute remains unresolved, since doing so provides Staff with greater visibility into issues within the interconnection process"). We find that there is value in Staff receiving this additional information. To provide parties additional time to resolve disputes before notifying Staff, we find that 30 business days, rather than 20 days, is appropriate.
31See, e.g., Dominion Comments at 10; Appalachian Voices Comments at 12; Cooperatives Comments at 7; Staff Comments at 17. The Cooperatives also recommend including a definition for "Bulk Electric System." We decline to include this definition at this time, since the term does not currently appear elsewhere in the Interconnection Regulations.

34The Cooperatives expressed concern that the cybersecurity requirements may create duplicative or conflicting requirements as between state and national standards. See Cooperatives Comments at 6. As Staff notes, the cybersecurity standards in the Interconnection Regulations are guidelines intended to harmonize utilities’ minimum cybersecurity standards with other national guidelines.

43See, e.g., Appalachian Comments at 12-14; CCSA Comments at 6-7.
44See, e.g., Appalachian Comments at 13-14; CCSA Comments at 7. CCSA additionally recommends establishing a quarterly interconnection reporting process. See CCSA Comments at 6. We concur with Staff that this request is addressed through the directive set forth in Case No. PUR-2022-00073 for each electric utility to submit quarterly updates on its DER interconnection activity. See Staff Response at 20.
45We note that in Case No. PUR-2022-00073, the Commission similarly declined to establish monetary penalties for delays in study completion because "study timelines could be affected by a variety of different factors, including certain factors outside of both the utility’s and interconnection customer’s control." See Commonwealth of Virginia, ex rel. State Corporation Commission, Ex Parte: In the matter considering utility distributed energy resource interconnection-related issues and questions, Case No. PUR-2022-00073, Doc. Con. Cen.

48See, e.g., Dominion Comments at 12-13; Cooperatives Comments at 3-5; CCSA Comments at 8-11; Staff Comments at 20-26. APCo does not appear to oppose the development of such a TIIR. See APCo Comments at 1. Appalachian Voices does not take a position on whether TIIRs are needed, but supports Commission oversight over the TIIR submissions. See Appalachian Voices Comments at 15. At this time, we do not find the creation of a technical advisory group to be necessary for the development of the TIIR documents. See CCSA Comments at 8.
49See, e.g., Proposed Rules; Staff Response at 20.
50See, e.g., Dominion Comments at 12. At this time, we do not require TIIR documents to include additional information on broader technical interconnection and grid integration issues. See CCSA Comments at 8-9. Nor do we choose to adopt performance criteria concerning inverter-based resources as part of the TIIR or require TIIR documents to reflect a risk-based approach to islanding mitigation. See CCSA Comments at 10. We note, however, that the Proposed Rules establish only the minimum information that must be included in TIIR documents. Nothing in the Proposed Rules prohibits utilities from including additional information as part of their TIIR submissions.
51The Commission will provide interested persons with the opportunity to comment on the proposed TIIR documents.
52We note that should a utility deem it necessary to redact a public-facing TIIR document, the Commission has existing processes and procedures to handle confidential or sensitive information. Further, if a document must be redacted, the utility should implement a process to make an unredacted version available upon request to developers. See Cooperatives Comments at 4.
53See, e.g., APCo Comments at 1; Cooperatives Comments at 4-5; Staff Response at 24-25. We note that this approach is similar to how Staff conducts administrative reviews for certain utility tariff filings. See Staff Response at 24.
54See, e.g., APCo Comments at 2-3; CUS Comments at 1-5. With regard to the Cooperatives request for clarification as to whether future changes to IEEE 1547 will be automatically incorporated into the Interconnection Regulations, we concur with Staff that the documents included in regulations are not subject to automatic updates when new standards are released. See Cooperative Comments at 3; Staff Response at 26.
20VAC5-314-10. Applicability and scope; waiver.
A. This chapter is promulgated pursuant to § 56-578 of the Virginia Electric Utility Regulation Act (§ 56-576 et seq. of the Code of Virginia). This chapter establishes standardized interconnection and operating requirements for the safe operation of electric generating facilities in Virginia. This chapter applies to utilities providing interconnections to retail electric customers, independently owned generators, and any other parties operating, or intending to operate, a distributed generating facility in parallel with utility systems. This chapter also applies to equipment used for the storage of electricity for later injection to utility systems. This chapter does not apply to customer generators operating pursuant to the Virginia State Corporation Commission's Regulations Governing Net Energy Metering (20VAC5-315) or those that fall under the jurisdiction of the Federal Energy Regulatory Commission (FERC).
If the utility has turned over control of its transmission system to a Regional Transmission Entity (RTE), and if the small generator interconnection process identifies upgrades to the transmission system as necessary to interconnect the small generating facility, then the utility will coordinate with the RTE, and the procedures in this chapter will be adjusted as necessary to satisfy the RTE's requirements with respect to such upgrades.
There are three review paths for the interconnection of generating facilities subject to this chapter in Virginia:
Level 1 - A request to interconnect a certified small generating facility (SGF) no larger than 500 kilowatts (kW) shall be evaluated under the Level 1 process.
Level 2 - A request to interconnect a certified SGF no larger than 2 MW and not qualifying for the Level 1 process shall be evaluated under the Level 2 process.
Level 3 - A request to interconnect an SGF not qualifying for the Level 1 process or Level 2 process, shall be evaluated under the Level 3 process.
The utility may place restrictions upon the interconnection of an SGF to a distribution feeder depending upon the characteristics of that feeder and the potential for upgrading it, as well as the nature of the loads and other generation on the feeder relative to the proposed point of interconnection. If the SGF cannot be safely and reliably interconnected to the utility's distribution feeder, the utility shall work with the interconnection customer (IC) to interconnect the SGF to the utility's transmission system. In such cases, the interconnection of the SGF may be governed by the regulations promulgated by FERC rather than the regulation of the Virginia State Corporation Commission.
The utility shall designate an employee or office from which the IC may request information concerning the interconnection application process. The name, telephone number, and email address of such contact employee or office shall be made available on the utility's website. Readily available electric system information relevant to the location of the proposed SGF shall be provided to the IC upon request, in writing, and may include interconnection studies and any other relevant materials, to the extent such provision does not violate confidentiality provisions of prior agreements or release critical infrastructure information. The utility shall comply with reasonable requests for such information unless the information is proprietary or confidential and cannot be provided pursuant to a prior confidentiality agreement.

B. The commission may waive any or all parts of the provisions of this chapter for good cause shown.
C. This chapter shall not apply to SGFs already interconnected as of October 15, 2020, unless:
1. The IC proposes a material modification; or
2. Application of this chapter is agreed to in writing by the utility and the IC.
D. This chapter shall apply if the IC has not actually interconnected the SGF as of October 15, 2020.
Any IC that has not executed an interconnection agreement with the utility prior to October 15, 2020, shall have 30 calendar days following the later of October 15, 2020, or the posted date of notice in writing from the utility to (i) demonstrate site control pursuant to Schedule 5 or 6 of 20VAC5-314-170; (ii) execute a combined study agreement as provided for in 20VAC5-314-70 or individual revised study agreements conforming with those set forth in Schedules 7, 8, and 9 of 20VAC5-314-170; and (iii) to post the deposit as specified in Schedule 6 of 20VAC5-314-170 minus any study costs previously paid.
Any IC that has executed an interconnection agreement with the utility prior to October 15, 2020, but where the utility has not actually interconnected the SGF or where the IC has not begun making payments, shall have 60 calendar days following the later of October 15, 2020, or the posted date of notice in writing from the utility to submit upgrade and interconnection facility payments (or financial security acceptable to the utility for attachment facilities and distribution upgrades) required pursuant to 20VAC5-314-50 F 2. Any amount previously paid by the IC at the time the deposit or payment is due under this subsection shall be credited toward the deposit amount or other payment required under this subsection.
Should an IC fail to comply with the provisions of this subsection following receipt of a written notice specifying how the IC failed to comply and the expiration of an opportunity to cure by the close of business on the 10th business day following the posted date of such notice to cure, the IC will lose its queue number and the interconnection request shall be deemed withdrawn.
E. Each SGF shall comply with IEEE 1547 Standard for Interconnection and Interoperability of Distributed Energy Resources with Associated Electric Power Systems Interfaces, 2018, and shall conform with the following minimum requirements:
1. Abnormal operating performance category: Category III capabilities must be supported for inverter-based SGFs. Rotating SGFs must meet Category I capabilities; and
2. Normal operating performance category: inverter-based SGFs must meet Category B capabilities and rotating SGFs must meet Category A capabilities.
F. Each utility shall post the utility's preferred settings in the utility's public-facing technical interconnection and interoperability requirements (TIIR) document. TIIR documents shall be submitted to the commission for approval with opportunity for public comment. Subsequent changes to TIIRs shall also be submitted to the [ commission Division of Public Utility Regulation ] for [ approval with opportunity for public comment administrative review ]. At a minimum, the following shall be identified in the TIIR documents: (i) voltage and frequency trip settings, (ii) frequency drop settings, (iii) activated reactive power control function and settings, (iv) voltage-active power mode activation and settings, (v) enter service settings, and (vi) communication protocols and ports requirements.
G. Each utility shall establish the utility's own utility-specific minimum cybersecurity standards based on, and not in conflict with, nationally recognized guidelines, including IEEE Standard 1547.3, Guide for Cybersecurity of Distributed Energy Resources Interconnected with Electric Power Systems, 2023, and the National Association of Regulatory Utility Commissioners' Cybersecurity Baselines for Electric Distribution Systems and DERs. These standards shall also include requirements for testing, validation, and auditing of the implemented cybersecurity measures. Each utility shall ensure these standards are publicly accessible by publishing these standards on the utility's respective websites.

20VAC5-314-38. Queue number and interdependent projects.
A. Queue number and queue position. The utility shall assign a queue number to an interconnection request based upon the date-stamp and time-stamp of receipt of a completed Interconnection Request Form by the utility. A later received Interconnection Request Form shall be assigned a higher numerical queue number than an earlier received Interconnection Request Form. The queue number and relative position of each interconnection request will be used to determine the cost responsibility for the upgrades necessary to accommodate the interconnection.
B. Interdependent projects.
1. Upon an IC's submission of an interconnection request for the 20VAC5-314-40 Level 1 interconnection process, 20VAC5-314-60 Level 2 interconnection process, or 20VAC5-314-70 Level 3 interconnection process, the utility shall review the interconnection request and make a preliminary determination of whether any interdependencies exist between the IC's proposed SGF and any other IC with a lower queue number. If the interconnection request is for a standby SGF with zero export, then the proposed SGF shall be studied as a Project A. For all other interconnections, any preliminary determination by the utility that the SGF does not create an interdependency will result in the interconnection request being preliminarily designated as a Project A, and the utility shall proceed immediately to either the 20VAC5-314-40, 20VAC5-314-60, or 20VAC5-314-70 Level 1, 2, or 3 study process, as applicable. At the 20VAC5-314-70 B scoping meeting, the utility shall advise the IC regarding its preliminary determination of whether interdependency would be created by the SGF. If no 20VAC5-314-70 B scoping meeting is scheduled, then the utility shall notify the IC in writing within five business days after making its preliminary determination of whether interdependency would be created by the SGF. If applicable, the Project A IC will pay the interconnection request study deposit required for the 20VAC5-314-70 Level 3 study process as identified in Schedule 6 of 20VAC5-314-170 in conjunction with the execution of the initial study agreement delivered by the utility pursuant to 20VAC5-314-70. An SGF preliminarily reviewed for system impacts and designated as a Project A may still be determined later to create an interdependency and may then be redesignated by the utility as an interdependent project during the 20VAC314-70 D system impact study process, thereby losing its Project A designation. Once the system impact study report is issued by the utility and the report designates an SGF as a Project A for purposes of the 20VAC314-70 E facilities study, the interconnection request shall retain this Project A designation during the facilities study, without change.
2. If the utility determines that the IC's proposed SGF is interdependent with one other interconnection request with a lower queue number (i.e., an earlier submitted interconnection request), the utility shall notify the IC in writing or at the 20VAC5-314-70 B scoping meeting that the interconnection request is designated as a Project B.
a. Following the 20VAC5-314-70 B scoping meeting, the Project B IC shall then have the option to either:
(1) Wait without further advancement of the interconnection request until Project A has executed a final interconnection agreement and begun making payments for any required upgrades, customer interconnection facilities, and other charges under 20VAC314-50 F. Under this option, Project B is not required to adhere to the timeline in 20VAC5-314-70 C until Project A has signed an SGIA and begun making payments or withdrawn its interconnection request; or
(2) Proceed Wait without further advancement of the interconnection request until Project A has received the [ Facilities System Impact ] Study Agreement pursuant to the 20VAC314-70 D system impact study process [ 10 1 ]. If the Project B IC chooses this option, the utility shall provide the Project B IC a Feasibility Study Agreement pursuant to 20VAC5-314-70 C or a System Impact Study Agreement pursuant to 20VAC5-314-70 D within 10 business days. If the Project B IC signs a [ System Impact Feasibility ] Study Agreement and pays the interconnection request study deposit pursuant to Schedule 6 of 20VAC5-314-170, the Project B shall receive a [ system impact feasibility ] study report that assumes the Project A interconnection request with the lower queue number completes construction and interconnection, and another [ system impact feasibility ] study report that assumes the Project A interconnect request with the lower queue number is not constructed and is withdrawn. [ Upon receipt of the feasibility study reports pursuant to 20VAC5-314-70 C or the determination that a feasibility study is not required, if the Project B IC signs a System Impact Study Agreement and pays the interconnection request study deposit pursuant to Schedule 6 of 20VAC5-314-170, the Project B shall receive a system impact study report that assumes the Project A interconnection request with the lower queue number completes construction and interconnection, and another system impact study report that assumes the Project A interconnect request with the lower queue number is not constructed and is withdrawn. ] The Project B IC is responsible for all costs for studying with and without Project A.
b. The utility shall not proceed to a Project B facilities study until after the Project B IC returns a signed Facilities Study Agreement to the utility and the utility has issued the 20VAC314-70 E facilities study report for Project A. Once the Project A facilities study report has been issued, the Project B IC shall then have the option to either:
(1) Wait without further advancement of the interconnection request until Project A has executed a final interconnection agreement and begun making payments for any required upgrades, customer interconnection facilities, and other charges under 20VAC314-50 F. Under this option, Project B is not required to adhere to the timeline in 20VAC5-314-70 E until Project A has signed an SGIA and begun making payments or withdrawn its interconnection request; or
(2) Proceed with a 20VAC314-70 E facilities study process. If the Project B IC chooses this option, the utility shall provide the Project B IC a Facilities Study Agreement pursuant to 20VAC5-314-70 E within 10 business days. If the Project B IC signs a Facilities Study Agreement prior to Project A committing to construction by signing the final interconnection agreement and beginning to make payments, then Project B's facilities study shall assume that the Project A interconnection request with the lower queue number will complete construction and interconnection. If Project A is later canceled prior to the Project A IC making payment for the required upgrades, the utility shall revise the Project B facilities study at the Project B IC's expense.
3. If the utility determines that the IC's proposed SGF is interdependent with more than one other interconnection request with a lower queue number (i.e., an earlier submitted interconnection request), the utility shall notify the IC at the 20VAC5-314-70 B scoping meeting and describe generally the number and type of interdependencies of interconnection requests with lower queue numbers.
a. The utility shall not study a project if it is interdependent with more than one earlier queued project. The utility will study a project when interdependency with only one earlier queued project exists. The removal of interdependency with multiple projects may be the result of (i) upgrades to the utility system that eliminate the cause of the interdependency, (ii) withdrawal of interdependent projects with lower queue numbers, or (iii) a lower queue number project signing an interconnection agreement and making payments identified in their SGIA.
b. Within five business days of an interconnection request becoming a Project B interconnection request that is interdependent with only one other interconnection request with a lower queue number, the utility shall schedule the 20VAC5-314-70 B scoping meeting and provide the new Project B IC the options specified in subdivision 2 a of this subsection. Upon being designated by the utility as a Project B, the IC's queue number shall be used to determine the order in which the interconnection request is studied under 20VAC314-70 D relative to all other interconnection requests.
C. Interconnection requests submitted prior to October 15, 2020. Other than as set forth in 20VAC5-314-10 C, nothing in this chapter affects an IC's queue number assigned before October 15, 2020. Interconnection requests that have received a system impact study report as of October 15, 2020, that did not identify any interdependency with another project shall be deemed a Project A. Any interconnection requests for which the utility has not completed the system impact study and issued a system impact study report (or combined study report, as applicable) to the IC as of October 15, 2020, shall be reviewed for interdependency pursuant to this section.
Should an IC fail to comply with 20VAC5-314-10 C following receipt of written notice specifying how the IC failed to comply and the expiration of an opportunity to cure by the close of business on the 10th business day following the posted date of such notice to cure, the IC shall lose its queue number and the interconnection request shall be deemed withdrawn.

5. A change to certified inverters with different specifications or different inverter control specifications or set-up than originally proposed [ , except as permitted under subdivision C 4 of this section ];
6. An increase of the maximum generating capacity of an SGF; or
7. A change reducing the maximum generating capacity of the SGF (i) by more than 25% before the Feasibility Study Agreement or Combined Study Agreement has been executed the amount specified in subdivision C 3 of this section [ or, ] (ii) by more than 10% after the Feasibility Study Agreement or Combined Study Agreement has been executed through more than one request [ , or (iii) by more than 10% after the Combined Study Agreement has been executed ].
C. Changes that do not qualify as material modifications are described as follows:
1. A change in ownership of an SGF; the new owner, however, will be required to execute a new Interconnection Request Form and study agreements for any study that has not been completed and the report issued by the utility;
2. A change or replacement of generating equipment, such as generators, inverters, solar panels, transformers, relaying, or controls, that is a like-kind substitution in size, ratings, impedances, efficiencies, or capabilities of the equipment specified in the original or preceding interconnection request;
3. A one-time change reducing the maximum generating capacity of the SGF by up to 75% before the [ Facilities System Impact ] Study Agreement;
4. [ A one-time change of certified inverters and transformer design, provided that (i) the inverters remain UL 1741 certified, (ii) the change does not increase the maximum AC output capability of the generating facility, and (iii) any associated transformer specification changes are limited to those required to accommodate the updated inverter model;
5. ] An increase in the DC/AC ratio that does not increase the maximum AC output capability of the generating facility;
4. [ 5. 6. ] A decrease in the DC/AC ratio that does not reduce the AC output capability of the generating facility by more than the amount specified in [ subdivision subdivisions B 7 and ] C 3 of this section.
5. [ 6. 7. ] A change in the DC system configuration to include additional equipment that does not impact the maximum generating capacity [ , daily production profile, ] or the proposed AC configuration of the SGF or energy storage device system, including DC optimizers, DC-DC converters, DC charge controllers, powerplant controllers, and energy storage devices systems such that the output is delivered during the same periods and with the same profile considered during the system impact study.
D. To the extent an IC proposes to modify any information provided in the interconnection request deemed complete by the utility, the IC shall submit any such modifications to the utility in writing. If the utility determines that the proposed modifications constitute a material modification, the utility shall notify the IC in writing within 10 business days that the modification is a material modification, and the interconnection request shall be withdrawn from the queue unless the IC withdraws the proposed material modification within 10 business days of receipt of the utility's written notification. If the modification is determined by the utility not to be a material modification, then the utility shall notify the IC in writing that the modification has been accepted and that the IC shall retain its queue number. An IC may seek an informal determination from the utility of whether a proposed modification constitutes a material modification in accordance with subdivision E of this section.
E. Modification inquiry.
1. Prior to making any modification, the IC may submit an informal modification inquiry in writing that requests the utility to evaluate whether the proposed modifications to the original or most recent interconnection request is a material modification. The IC shall provide specific details on all changes that are to be considered by the utility.
2. In response to IC's informal request, if the utility evaluates the proposed modifications and determines that the changes are not material modifications, the utility shall inform the IC in writing within 10 business days. If the IC wishes to proceed with the proposed modifications, the IC shall submit a revised Interconnection Request Form that reflects the approved modifications.
20VAC5-314-70. Level 3 interconnection process.
A. The Level 3 interconnection process shall be used by an IC proposing to interconnect an SGF with the utility system if the SGF does not pass or qualify for the Level 1 or Level 2 interconnection processes. As needed, a scoping meeting, feasibility study, system impact study, and facilities study shall precede the preparation of an SGIA (Schedule 10 of 20VAC5-314-170). Any of the studies may be combined by mutual, written agreement of the parties along with payment of applicable interconnection study deposit, set forth in Schedule 6 of 20VAC5-314-170. Such agreement for a combined study shall, at a minimum, include milestones for completion. The combined study timeframes and fees shall not exceed the aggregate timeframes and fees of the individual studies as specified in this section. To maintain its position in the utility's interconnection queue, the IC must execute the agreement for combined study, return it to the utility, and pay the interconnection request study deposit set forth in Schedule 6 of 20VAC5-314-170 within 15 business days after receipt of the agreement. If the IC fails to return the executed agreement for combined study or make the full payment of the interconnection request study deposit within 15 business days after receipt of the agreement, the interconnection request shall be deemed withdrawn, and the interconnection request shall lose its place in the utility's interconnection queue.
B. Scoping meeting.

If the parties agree to not perform a feasibility study, the utility shall provide the IC a System Impact Study Agreement (Schedule 8 of 20VAC5-314-170) including an outline of the scope of the study and an estimate of the cost to perform the study no later than 10 business days after the scoping meeting or five business days after the decision is made to not have a scoping meeting.
2. To maintain its position in the utility's interconnection queue, the IC must execute the Feasibility Study Agreement, return it to the utility, and pay the interconnection request study deposit set forth in Schedule 6 of 20VAC5-314-170 within 15 business days after receipt of the agreement. If the IC fails to return the executed Feasibility Study Agreement or make the full payment of the interconnection request study deposit within 15 business days after receipt of the agreement, the interconnection request shall be deemed withdrawn and the interconnection request shall lose its place in the utility's interconnection queue.
3. A feasibility study shall identify any potential adverse system impacts that would result from the interconnection of the SGF.
4. Feasibility study costs will be deducted from the interconnection request study deposit pursuant to Schedule 7 of 20VAC5-314-170.
5. The feasibility study shall be based on the technical information provided by the IC in the Interconnection Request Form, as may be modified as the result of the scoping meeting. The utility reserves the right to request additional technical information from the IC as may reasonably become necessary consistent with Good Utility Practice during the course of the feasibility study and as designated in accordance with the standard small generator interconnection procedures. All modifications made to the interconnection request shall be made in writing to the utility. If the IC submits a modification to its interconnection request in writing and the utility determines the modification is not a material modification, the time to complete the feasibility study may be extended by mutual, written agreement of the parties.
6. In performing the feasibility study, the utility shall rely, to the extent reasonably practicable, on recent studies. The IC shall not be charged for such existing studies; however, the IC shall be responsible for charges associated with any new study or modifications to existing studies that are reasonably necessary to perform the feasibility study.

7. In cases where system upgrades are required, the utility shall transmit the facilities study report within 45 business days after receipt of the completed Facilities Study Agreement. In cases where no system upgrades are necessary and the required facilities are limited to the IC's interconnection facilities and attachment facilities only, the utility shall transmit the facilities study report within 30 business days after receipt of the completed Facilities Study Agreement. If the utility expects to miss the 45-business-day or 30-business-day deadline, the utility must notify the IC in writing at least five business days before the deadline and provide a new expected completion date [ to the extent the information is available ].
F. Construction planning meeting.
1. Within 15 business days of receipt of the report for the final study (i.e., the facilities study or, if applicable, a combined study that satisfies all study requirements), the IC shall request a construction planning meeting where failure to comply shall result in the interconnection request being deemed withdrawn. The construction planning meeting request shall be in writing and shall include the IC's reasonably requested date for completion of the construction of the customer's interconnection facilities and upgrades.
2. The construction planning meeting shall be scheduled within 15 business days of the request from the IC as stated in subdivision F 1 of this section, or as otherwise mutually agreed to in writing by the parties.
3. The purpose of the construction planning meeting is to identify the tasks for each party and discuss and determine the milestones for the construction of the system upgrades and attachment facilities. Agreed upon milestones shall be specific as to scope of action, responsible party, and dates of deliverables and shall be recorded in the SGIA (see Schedule 10 of 20VAC5-314-170) to be provided to the IC.

B. In the event of a dispute, either party shall provide the other party with a written notice of dispute. The notice shall describe in detail the nature of the dispute. The parties shall make a good faith effort to resolve the dispute informally within 10 business days.
C. If the dispute has not been resolved within 10 business days after receipt of the notice, either party may seek resolution assistance from the Division of Public Utility Regulation where the matter will be handled as an informal complaint.
Alternatively, the parties may, upon mutual agreement, seek resolution through the assistance of a dispute resolution service. The dispute resolution service will assist the parties in either resolving the dispute or in selecting an appropriate dispute resolution venue (e.g., mediation, settlement judge, early neutral evaluation, or technical expert) to assist the parties in resolving their dispute. Each party shall conduct all negotiations in good faith and shall be responsible for one-half of any costs paid to neutral third parties.
D. If the dispute remains unresolved, either party may petition the commission to handle the dispute as a formal complaint or may exercise whatever rights and remedies it may have in equity or law.
E. The specified time periods for the interconnection request shall be tolled during the period in which the parties are engaged in any of the dispute resolution processes described in this section. Tolling shall commence upon the initiation of a dispute resolution process and shall end upon the termination of such process. This tolling ensures that neither party is prejudiced by the time taken to resolve the dispute through informal or formal mechanisms. If the dispute remains unresolved after [ 20 30 ] business days, the utility shall provide a written notice to commission staff at the Division of Public Utility Regulation.
20VAC5-314-150. Capacity of the small generating facility.
A. If the interconnection request is for an increase in capacity for an existing SGF, the interconnection request shall be evaluated on the basis of the new total capacity of the SGF.
B. If the interconnection request is for a facility that includes multiple energy production or energy storage devices systems at a site for which the IC seeks a single point of interconnection, the interconnection request shall be evaluated on the basis of the maximum generating capacity of the facility.
C. The interconnection request shall be evaluated using the maximum capacity that the SGF is capable of injecting into the utility's electric system. However, if the maximum generating capacity that the SGF is capable of injecting into the utility's electric system is limited (e.g., through use of a control system, power relays, or other similar device settings or adjustments), then the IC must obtain the utility's agreement, with such agreement not to be unreasonably withheld, that the manner in which the IC proposes to implement such a limit will not adversely affect the safety and reliability of the utility's system. If the utility does not so agree, then the interconnection request must be withdrawn or revised to specify the maximum capacity that the SGF is capable of injecting into the utility's electric system without such limitations. Nothing in this section shall prevent a utility from considering an output higher than the limited output, if appropriate, when evaluating system protection impacts.
20VAC5-314-160. Insurance, liability, and indemnification.
A. For an SGF with a rated capacity not exceeding 10 kW, the IC, at its own expense, shall secure and maintain in effect during the term of the agreement, liability insurance with a combined single limit for bodily injury and property damage of not less than $100,000 for each occurrence.
For an SGF with a rated capacity exceeding 10 kW but not exceeding 500 kW, the IC, at its own expense, shall secure and maintain in effect during the term of the agreement, liability insurance with a combined single limit for bodily injury and property damage of not less than $300,000 for each occurrence.
For an SGF with a rated capacity exceeding 500 kW, the IC, at its own expense, shall secure and maintain in effect during the term of the agreement, liability insurance with a combined single limit for bodily injury and property damage of not less than $2 million for each occurrence.
An IC of sufficient creditworthiness, as determined by the utility, may propose to provide this insurance via a self-insurance program if it has a self-insurance program established in accordance with commercially acceptable risk management practices, and such a proposal shall not be reasonably rejected.
B. Certificates of insurance evidencing the requisite coverage and provision shall be furnished to the utility prior to the date of interconnection of the SGF, as required by the utility. The utility shall be permitted to periodically obtain proof of current insurance coverage from the IC in order to verify continuing proper liability insurance coverage. The utility reserves the right to refuse to commence or continue interconnected operations unless evidence is provided that required insurance coverage is in effect at all times.
C. Utility and IC liability to the other party for any loss, cost, claim, injury, liability, or expense, including reasonable attorney fees, relating to or arising from any act or omission pursuant to this chapter shall be limited to the amount of direct damage actually incurred. In no event shall either party be liable to the other party for any indirect, special, incidental, consequential, or punitive damages of any kind.
D. The utility and the IC shall at all times indemnify, defend, and save the other party harmless from any damages; losses; claims, including claims and actions relating to injury or death of any person or damage to property; demand; suits; recoveries; costs and expenses; court costs; attorney fees; and all other obligations by or to third parties arising out of or resulting from the other party's action or inaction of its obligations pursuant to this chapter on behalf of the indemnifying party, except in cases of gross negligence or intentional wrongdoing by the indemnified party.

WHEREAS, the Interconnection Customer desires to interconnect the SGF with the Utility's system; and
WHEREAS, the Utility has completed a system impact study and provided the results of the study to the Interconnection Customer; and
WHEREAS, the Interconnection Customer has requested the Utility to perform a facilities study to specify and estimate the cost of the equipment, engineering, procurement, and construction work needed to implement the conclusions of the system impact study in accordance with Good Utility Practice to physically and electrically connect the SGF with the Utility's system.
NOW, THEREFORE, in consideration of and subject to the mutual covenants contained in this Agreement the Parties agreed as follows:
1.0 The terms defined in Schedule 1 of 20VAC5-314-170 shall apply to this Schedule 9 of 20VAC 5-314-170.
2.0 The Interconnection Customer elects and the Utility shall cause a facilities study consistent with the standard small generator interconnection procedures.
3.0 The scope of the facilities study shall be subject to data provided in Attachment A to this Agreement.
4.0 The facilities study shall specify and estimate the cost of the equipment, engineering, procurement, and construction work needed to implement the conclusions of the feasibility study or system impact study and to allow the SGF to be interconnected and operate safely and reliably.
5.0 Facilities study costs will be deducted from the interconnection request study deposit, as set forth in Schedule 6 of 20VAC5-314-170.
5.1 Study cost shall be the Utility's actual incremental costs and will be invoiced to the Interconnection Customer no later than 60 business days after the study is completed and delivered and will include a summary of professional time. Actual study costs may be reconciled during the final accounting process described in Article 6 of the Interconnection Agreement, as applicable.
5.2 The Interconnection Customer shall pay any study costs that exceed the deposit within 20 business days on receipt of the invoice or resolution of any dispute. If the deposit exceeds the invoiced fees, the Utility shall refund the excess within 20 business days of the invoice without interest.
6.0 Design for any required customer's interconnection facilities, attachment facilities, or distribution upgrades shall be performed under the facilities study. The Utility may contract with consultants to perform activities required under the facilities study. The Interconnection Customer and the Utility may agree to allow the Interconnection Customer to separately arrange for the design of some of the customer's interconnection facilities. In such cases, facilities design will be reviewed or modified prior to acceptance by the Utility, under the provisions of the facilities study. If the Parties agree to separately arrange for design and construction, and provided security and confidentiality requirements can be met, the Utility shall make sufficient information available to the Interconnection Customer in accordance with confidentiality and critical infrastructure requirements, to permit the Interconnection Customer to obtain an independent design and cost estimate for any necessary facilities.
7.0 The facilities study shall also identify (i) the electrical switching configuration of the equipment, including transformer, switchgear, meters, and other station equipment; (ii) the nature and estimated cost of the attachment facilities and distribution upgrades necessary to accomplish the interconnection; and (iii) an estimate of the time required to complete the construction and installation of such facilities.
