Lithium-ion chosen first, but not the only option for California’s long-duration energy storage needs
Energy Storage News
Regular readers of Energy-Storage.news will likely be aware of the increasing role played in California’s energy landscape — and more specifically its clean energy landscape — by Community Choice Aggregators (CCAs).
Non-profit electricity suppliers allowing their member-customers to choose which sources their power comes from, CCAs are signing ever-greater volumes of contracts for solar, wind, renewables-plus-storage and standalone energy storage resources.
According to CalCCA, an organisation which works to support numerous CCAs at legislative and regulatory level, as of November last year power purchase agreements (PPAs) had been signed for more than 2.6GW/9.2GWh of battery storage with average contract length being 17 years, by California’s CCAs.
But it isn’t just the sheer scale of resources being contracted for. The fact that many CCAs and their customers are opting for greener sources of energy is leading to innovation in contract structures too.
