The solution lies in alternative energy sources like battery energy storage systems (BESS). Battery energy storage is an evolving market, continually adapting and innovating in response to a changing energy landscape and technological advancements.
Growth and Maturation of Battery Storage in California Over the past several years, the deployment of battery storage systems has grown significantly throughout California, growing from 500 megawatts (MW) in 2019 to over 13,300 MW statewide in 2024. Likewise, battery storage system technologies and standards have also matured over time.

Battery storage systems are one of the key technologies California relies on to enhance reliability and reduce dependency on polluting fossil fuel plants. Battery storage systems soak up clean energy in the daytime when the sun is shining, store that electricity, and then export it to the grid in the evening hours when the sun is down.
Non-battery systems, on the other hand, range considerably more depending on duration. Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours.
The cost categories used in the report extend across all energy storage technologies to allow ease of data comparison. Direct costs correspond to equipment capital and installation, while indirect costs include EPC fee and project development, which include permitting, preliminary engineering design, and the owner's engineer and financing costs.
Energy storage and its impact on the grid and transportation sectors have expanded globally in recent years as storage costs continue to fall and new opportunities are defined across a variety of industry sectors and applications.

A separate analysis involves assumptions for electric power generation plant costs for various technologies, including utility-scale photovoltaics and both onshore and offshore wind turbines used in the Electricity Market Module.
