Calpine's primary point of concentration in this proceeding is on the procurement process and the Commission's role in developing fair, open and transparent competitive solicitations that provide for head-to-head comparison of resource options. Calpine urges the Commission to ensure such a solicitation process by (1) prohibiting the IOUs from excluding existing generation resources from participating in RFOs; (2) limiting cost-of-service bids to costs and operating performance standards contained in the bid package; (3) promoting all-source RFOs that allow head-to-head competition between UOG and PPAs; (4) disallowing the use of DE by the IOUs when comparing PPAs; and (5) not allowing a preference for AB 1576 repowering projects. Calpine argues that the adoption of these recommendations will promote competitive solicitations that result in the procurement of the least cost/best fit resources.
