About the Company

Field

Develops, builds, operates grid-scale battery storage

The company develops, builds, and runs large-scale battery storage projects to support a greener power grid. It starts by creating battery storage sites in the UK and Europe, which store renewable energy when plenty of sun or wind is available and release it when the grid needs it, reducing reliance on carbon-heavy power. The business also builds its own technology platform to optimize how these assets are used, helping projects scale faster and earn better returns. What sets it apart is its vertically integrated approach—covering development, construction, operation, and asset optimization in one company—and its plan to expand across regions to tackle the climate problem. Its goal is to help reach net zero by solving energy storage, grid reliability, and heating decarbonization at scale.
