Fourth Power

Fourth Power is a thermal battery energy storage company. Our technology makes renewable energy an on-demand energy source through utility-scale thermal storage. We can harness today’s wasted wind and solar production to respond to grid needs at a cost competitive with fossil fuels. Our modular battery can provide 5 to 10 hours of storage to meet needs now and scale with renewable deployment for needs up to 100 hours and any increment in between. With the ability to provide short- and long-duration energy storage (LDES), we can start small and grow with the grid to save consumers money and ensure a clean energy future.
