The California Public Utilities Commission approved most, but not all, rules needed to launch the first renewables solicitation last month. Meant to complete the equation is a plan on parameters for utility selection of ?least cost? and ?best fit? renewables bids. ?Least cost? includes bidders? energy and capacity costs and utility operating costs. ?Best fit? is linked to a utility?s needs. Overall, the plan would adopt Pacific Gas & Electric?s method for bid selections?with conditions. PG&E?s proposal focuses on a bid?s market value, calculating transmission and integration costs, evaluating portfolio fit, and considering factors other than bid price. For the first solicitation, bidders can submit bids at any price into multiple solicitations and withdraw bids until a utility short-lists the proposals. At that point, the bidder would have five business days to withdraw conflicting bids before negotiating the renewables deal.
