The company was already partnering with Tesla to install Powerwalls with its solar installations.
Sunrun customers who enroll will be participating in ERCOT’s Aggregated Distributed Energy Resources pilot program aimed at strengthening grid reliability by networking together customer-sited storage devices to serve as a resource for the wholesale electricity market. Additionally, customer Powerwall batteries will also help to lower the costs of energy at the wholesale level. The resulting energy cost savings will be shared with customers.
We previously reported on a Tesla Electric customer covering their entire energy needs plus making over $1,000 in 2023 with 3 Powerwalls and 12 kW of solar.
