Example of a cost breakdown for a 1 MW / 1 MWh BESS
Initially, the flexibility requirements of modern power systems are defined, followed by an exploration of the flexibility assets and operational flexibility capabilities of data centres.
BESS stands for Battery Energy Storage Systems, which store energy generated from renewable sources like solar or wind. The stored energy can then be used when demand is high, ensuring a stable and reliable energy supply.
As of most recent estimates, the cost of a BESS by MW is between $200,000 and $450,000, varying by location, system size, and market conditions.
Modern BESS solutions often include sophisticated software that helps manage energy storage, optimize usage, and extend battery life. This software can be an added expense, either as a one-time purchase or a subscription model. Effective software can lead to cost savings over time by ensuring the system operates at maximum efficiency.
The cost of BESS has fallen significantly over the past decade, with more precipitous drops in recent years: 2025: Global average turnkey BESS costs fell to ~$117/kWh, a 31% year‑over‑year decline from 2024, with China‑focused competitive pricing as low as $63/kWh in some tenders.
