Castor Storage is a utility‑scale battery energy storage project designed to strengthen grid reliability while supporting affordable energy for Nevada ratepayers. The project is strategically sited within an existing permitted energy corridor, minimizing land disturbance and making efficient use of established infrastructure. By storing energy when supply is abundant and delivering it during periods of peak demand, Castor will help stabilize the grid and reduce overall system costs.

The project will bring long‑term local investment, support construction and operational jobs, and advance a more resilient energy system. Through low‑impact siting and responsible design, Castor will deliver meaningful community and grid benefits while contributing to a reliable, cost‑effective energy future.
