Reposit Power is a distributed energy company that integrates software with solar battery systems to build virtual power plants. It offers an add-on that integrates with customer-owned solar and solar battery setups, learns when and how households use electricity, and predicts how much solar they will generate up to 24 hours in advance. The company sells excess energy back to the grid at peak times (when the cost is high) and waits for off-peak periods (when the cost is lowest) to fill the homeowner's solar battery up with energy again if needed.
