Clean energy must be dependable and affordable for every consumer, even during high-demand periods. Our grid-connected battery storage technologies help meet the clean energy demands of an increasingly electrified world. With a total of 590 MW of battery storage in operation and more than 2,000 MW of battery storage in development, Calpine is playing a pivotal role in securing America’s energy future.

What is Battery Energy Storage?

Battery energy storage is a reliable, cost-effective method of storing excess energy during periods of high supply and low demand, releasing it during peak demand times to maintain grid stability and prevent service disruptions like power outages. In addition, battery energy storage provides other applications and benefits such as regulating voltage for protection of the grid.

Step 1: Energy Produced

Energy is produced from power plants and, at times, supply is higher than demand.

Step 2: Charge Batteries

Excess energy is delivered to a battery energy storage system.

Step 3: Deliver Energy

When demand for energy rises, batteries release stored energy to deliver reliable service to homes and businesses.
