California is one of the deepest utility scale solar markets in the country, and the buyers in the CAISO footprint run their own solicitations to meet resource adequacy and clean energy obligations. For a developer, the CAISO market means many separate buyers, the investor owned utilities, the community choice aggregators, and the public power agencies, each soliciting solar and solar paired storage on its own schedule.
Who Buys Solar in the CAISO Market
Demand in California comes from the load serving entities that carry resource adequacy obligations. The community choice aggregators, including Clean Power Alliance, run requests for offers for solar and solar plus storage, the investor owned utilities solicit under their procurement plans, and the public power agencies issue their own. Each runs a request for offers with a prequalification step and its own evaluation.
Why CAISO Solar Tenders Are Easy to Miss
The CAISO market has no single posting place. Each community choice aggregator, utility, and public power agency runs its own request for offers on its own site and schedule, many require prequalification to receive the documents, and resource adequacy value and the interconnection position drive the evaluation. A developer watching one buyer misses the rest of a fragmented market.
