Solar and wind power rise and fall with the weather, so the supply is uneven. REAP storage smooths this out: a battery energy storage system (BESS) — a system that stores energy so it can be used later — captures clean energy when it is plentiful and releases it when it is needed, turning an on-and-off supply into steady, dependable power for the grid.
This means a solar or wind farm can store the energy it would otherwise waste, deliver power more evenly, and help keep the electricity grid stable.
What this gives you
- Store clean energy instead of wasting it at solar and wind farms
- Smooth out the ups and downs of solar and wind output
- Save energy when the sun and wind are strong, use it in the evening when demand rises
- Steadier power supply — helps keep voltage and frequency stable
