How much battery storage will California have in 2025?

From 2018 through the first quarter of 2025, battery storage capacity in California increased from 500 megawatts (MW) to more than 15,700 MW with an additional 8,600 MW planned to come online by the end of 2027. The state projects 52,000 MW of battery storage will be needed by 2045.

Should energy storage be included in the California electricity grid?

California legislation under AB 2514 (Skinner, Chapter 469, Statutes of 2010) encourages utilities to incorporate energy storage into the electricity grid.

Why is energy storage important in California?

California is a world leader in energy storage with the largest fleet of batteries that store energy for the electricity grid. Energy storage is an important tool to support grid reliability and complement the state's abundant renewable energy resources.

When should a battery be charged and discharged?

Often a battery is charged whenever resources are available and discharged whenever load occurs without going through a complete charge/discharge cycle, so a long analysis period (e.g., 1 year) may be needed to capture when the battery is completely discharged (to minimum set point) and completely charged.

What is the maximum energy accumulated in a battery?

The maximum amount of energy accumulated in the battery within the analysis period is the Demonstrated Capacity (kWh or MWh of storage exercised). In order to normalize and interpret results, Efficiency can be compared to rated efficiency and Demonstrated Capacity can be divided by rated capacity for a normalized Capacity Ratio.

What is an energy storage system?

The Public Utilities Code defines an energy storage system as a commercially available technology that absorbs energy, storing it for a specified period, and then dispatches the energy.
