According to the report, the global grid-scale energy storage market is projected to expand from USD 27.6 billion in 2025 to USD 107.8 billion by 2035, registering a CAGR of 14.6%, the highest during the forecast period. The grid-scale energy storage market is expanding as more renewable energy generation is added to the power grid, demand for electricity continues to rise, the power grid is being modernized, and the grid requires more flexibility and resilience.
Battery systems are being used on a scale of 10s of MWs or more to help manage renewable intermittency, meet peak demand, and supply ancillary grid services. In 2025, BYD Energy Storage secured a 12.5 GWh contract for solar grid-scale battery storage with the Saudi Electricity Company (SEC), contributing to the integration of renewable energy and grid stability.
Further, the International Energy Agency (IEA) reports that global battery storage deployments are also gaining momentum as nations increase their renewable energy deployment and bolster energy security goals. These are helping to speed the deployment of utility-scale energy storage and a more resilient and renewable powered electricity system.
Key Driver, Restraint, and Growth Opportunity Shaping the Global Grid-Scale Energy Storage Market
Grid-scale energy storage systems experience gradual battery degradation due to repeated charge-discharge cycles, environmental conditions, and intensive operational requirements. Capacity reduction with time may impact project economics, maintenance needs, and battery replacement investment; thereby leading to potential concern for asset long-term performance and return on investment.
Reduce diesel reliance in remote areas and islands is creating grid-scale energy storage deployment opportunities. Battery systems and renewable energy can enhance energy security, reduce fuel costs and deliver reliable power where grid access is not feasible. Storage-backed microgrids are becoming a growing investment priority for utilities and governments aiming to more quickly meet the growing demand for clean energy in underserved regions.
