CPUC Blends Utilities’ Renewable Auction Plans
Addresses frequency, timing, and eligibility requirements
Update courtesy of Utility Regulatory News #4035: Reviewing advice letters submitted by the state’s three largest electric utilities following a California Public Utilities Commission decision in December that had outlined an auction process for the procurement of energy supplies from small renewable facilities, the commission found that certain modifications were needed in order for the associated solicitations to meet the commission’s vision for its renewable auction mechanism (RAM).
The commission noted that the three utilities - Pacific Gas & Electric Co. (PG&E), San Diego Gas & Electric Co. (SDG&E), and Southern California Edison Co. (SCE) - had proffered advice letters that varied from each other as well as from some of the terms set forth in the commission’s December order. For instance, the commission pointed out, PG&E and SCE had proposed holding only one renewable auction per year, whereas the commission had specifically mandated a total of four auctions over the next two years. The commission also noted that although the December decision had explicitly provided for simultaneous auctions, the utilities had not coordinated their RAM schedules, and SCE had actually recommended that their auctions be staggered purposely. The utilities also disagreed as to what facilities could participate in the auctions and what minimum and maximum capacity limits should apply.
The commission nixed PG&E’s approach to eligibility, which would have restricted participation to new facilities only. Instead, the commission determined that SCE’s terms were preferable in that they would allow both new and existing renewable facilities to participate. As to capacity thresholds, the commission found that certain aspects of both PG&E’s and SDG&E’s proposals were apt. It thus ruled that eligibility would be based on a contract minimum of 1 MW and a project size minimum of 500 kW. However, the commission agreed that projects should be allowed to aggregate, so as to meet the 1-MW contract minimum if their capacity was less than that. Aggregation would be capped at 5 MW, however.
The utilities were instructed to file new advice letters showing compliance with the commission’s directives. For the full story, subscribe to URN.
