FAQS about Energy storage battery revenue

How does a battery energy storage system make money?

Both shorter-duration and longer-duration battery energy storage systems earned a majority of their revenues from Ancillary Services in January and February. However, shorter-duration systems earned 36% of their revenues from Regulation services, while longer-duration systems earned 43% of their revenues from Responsive Reserve.

How does ancillary services affect battery energy storage revenues?

Across January and February 2024, batteries participated heavily in Ancillary Services, earning 85% of their revenues from these markets. Historically, battery energy storage revenues have been dominated by Ancillary Services - particular Regulation Up and Down, and Responsive Reserve (RRS).

How much money did battery energy storage systems make in ERCOT?

Across January and February 2024, battery energy storage systems in ERCOT earned $55,000k/MW (annualized). But which markets did these revenues come from?

How will energy arbitrage affect battery energy storage systems?

As the amount of operational battery capacity increases, these Ancillary Services will become saturated - pushing prices down. And, as this happens, battery energy storage systems will start to earn a larger proportion of their revenues from Energy arbitrage.

What is the future of battery energy storage?

As batteries become more efficient and affordable, adopting energy storage systems is likely to accelerate the market for battery energy storage. In research conducted by our analysts, over the next five years, capacity for energy storage worldwide is expected to grow by 55 % and reach 260 GW in 2026.

Do investors underestimate the value of energy storage?

While energy storage is already being deployed to support grids across major power markets, new McKinsey analysis suggests investors often underestimate the value of energy storage in their business cases.
