Battery Energy Storage


Capstone offers clean, cost-effective modular Lithium-Ion battery energy storage systems (BESS) for a wide range of on or off-grid applications. Our containerized BESS product can be used as energy-storage devices for power harnessed from renewables or the grid, as uninterruptible power supply when grid power is available, or as main power sources when it is not. Paired with Capstone’s foundational microturbine technology, the solution guarantees a continuous reliable energy supply.

In a typical application, a Capstone microturbine serves as the main power source in sites where grid power is unavailable or unreliable. The microturbine is flexible and scalable and the output power can be increased or decreased according to demand.
