Federal Solar Transmission & Interconnection(8-FD)
In order to interconnect solar power generation facilities to transmission lines, developers must obtain an Interconnection Agreement from the appropriate transmission service provider. The procedures and requirements for obtaining an Interconnection Agreement vary depending on whether the developer is a large generator or a small generator.
Developers which qualify as public utilities and own, control or operate facilities used for transmitting electric energy in interstate commerce must have on file standard procedures and a standard agreement for interconnecting generators larger than 20MW pursuant to FERC Order No. 2003. The developer, the Interconnection Customer (IC), must negotiate for an Interconnection Agreement with the Transmission Provider (TP). To begin this procedure, the IC must submit an Interconnection Request Form, a refundable deposit of $10,000, and document showing control of the proposed site to the TP. FERC Order No. 2003 – Appendix C, Section 3. Developers will be required to participate in a scoping meeting for the purposes of discussing alternative interconnection options, exchange information that would be reasonably expected to impact such interconnection options, and to determine potential feasible Points of Interconnection. FERC Order No. 2003 – Appendix C, Section 3.3.4. The TP and IC will commence an in-depth interconnection analyses process composed of three separate studies and one optional study following the scoping meeting. FERC Order No. 2003 – Appendix C, Sections 6-10. Following all necessary studies, a Draft Interconnection Agreement will be developed. This Draft Interconnection Agreement will be negotiated between the TP and IC to produce and execute the Final Interconnection Agreement.
Developers whose facility qualifies as a Small Generating Facility must comply with Small Generator Interconnection Procedures (SGIP), which contain technical procedures the IC and TP must follow after request for interconnection. There are three ways outlined to evaluate the Interconnection Request: the default Study Process (for Small Generating Facilities no larger than 20MW), the fast track process (for a certified Small Generating Facility that meets certain eligibility requirements), and the 10KW Inverter Process (for a certified inverter-based Small Generating Facility no larger than 10KW). All three processes are designed to ensure that the proposed interconnection will not endanger the safety and reliability of the TP’s transmission system. FERC Order No. 792. The IC may request information from the TP concerning the application process through an informal request. FERC Order No. 792 – Appendix C, Section 1.2.1. The IC may also choose to submit a formal written request to the TP for a pre-application report on a proposed project at a specific site. FERC Order No. 792 – Appendix C. Section 1.2.1. The IC must submit its Interconnection Request to the TP, together with the processing fee or deposit specified in the Interconnection Request. The TP is required to conduct a technical screening of the proposed interconnection, notify the IC of the results, and include with the notification copies of the analysis and data underlying the TP’s determinations. FERC Order No. 792 – Appendix C, Sections 2.2.2 – 2.2.4. Once the interconnection is approved, the TP will provide the IC with an executable Interconnection Agreement. Following the execution of an Interconnection Agreement, the IC will be required to comply with supplemental reviews and technical screenings. FERC Order No. 792 – Appendix C, Section 2.4.4.
