264 Generator Interconnection Agreements Feed-In-Tariff Projects Jamie Asbury Deputy Energy Manager, Business/Regulatory April 4, 2016
Background Information All Projects Projects with generation intended for wholesale sale are subject to and processed under IID s tariff. Two studies performed: System Impact Study (reliability impacts on the grid) Facilities Study (infrastructure to mitigate impacts) Planning and Engineering ensured reliable grid: 265 Reliable but less costly interconnections are cost saving for both IID and the developer Makes for more robust grid thereby attracting additional development. 2
IID s Feed-In-Tariff Background In 2009, Senate Bill 32 required large utilities to implement a feed-in-tariff program. Subsequent adoption of SB 1332 in 2012, requires publicly-owned utilities serving 75,000 or more customers to offer an FIT program by July 1, 2013. SB 1332 set the processing of requests on a first-come, first-served basis. SB 1332 set a state-wide cap of 750 MW; IID s share of the 750 MW cap was set at 14 MW. IID board received an informational FIT program presentation on May 28, 2013 and subsequently approved the FIT program and rate on June 11, 2013. IID board received an informational item reference amendment to the open access transmission tariff on June 11, 2013 to accommodate a small generator interconnection process; subsequent approval on June 25, 2013. IID processed the requests in the order received pursuant to SB 1332. 266 3
Basic Feed-In-Tariff Rate Components IID developed a pro forma purchase power agreement. Utilities offer 10, 15 and 20 year standard power purchase agreements (no negotiation of terms and conditions); IID opted for a 20-year term. Seasonal time-of-delivery tariff based on the following cost components: Renewable Energy Greenhouse Gas Reduction Peak Demand Reduction Avoided Transmission and Distribution Improvements IID s board adopted a PPA rate based on a time-of-day delivery period and contains a 1.5 percent fixed annual escalation factor. 267 4
