Why we like it
Grid-scale batteries provide fast, flexible capacity to power systems with growing intermittent generation. They can shift electricity across the day, support system balancing and ease network constraints, with multiple revenue streams available from the same asset.
We favour projects where grid position, route-to-market and revenue stacking are well understood, and where the investment case is not dependent on one unusually high ancillary-service price.
Market context
Battery storage was the fastest-growing power technology globally in 2025. The IEA estimates that 108 GW of new capacity was deployed during the year, up 40% from 2024, with around 80% of additions at utility scale.
Falling system costs are broadening use cases, but value is increasingly determined by location, grid access, duration and commercial optimisation rather than simply owning battery capacity.
