About Base Power
Designs, installs, and maintains large home batteries, pooling them into a virtual power plant to sell grid services and capacity. Started in Texas.
Base Power is an American energy company founded in 2023 in Austin. It installs large batteries in private homes, retains ownership of them, and sells the customer electricity cheaper than the standard rate, while pooling thousands of batteries into a virtual power plant that stores cheap energy and feeds it back to the grid when prices rise. Starting in Texas, the company expanded into Illinois in June 2026; fleet capacity passed 500 MWh, and it has signed more than 200 MW of contracts with utilities and cooperatives. Installations run at a pace of about 100 batteries a day, and customer churn is near zero. In August 2026 the company raised $1B in a Series D round at a $13B valuation — triple the valuation from ten months earlier; total funding raised exceeds $2.2B.

Key highlights
- A second plant in Austin. The company is building a second production facility that should double battery output, opening in 2027. More batteries per month means faster fleet growth, and higher-volume output lowers the cost of each system.
- New states with retail choice. Plans include California, New York, Massachusetts, Connecticut, and other states where residents choose their own electricity provider. The Illinois launch showed the model works even where market rules differ from Texas's.
- Utility contracts. Cooperatives and municipal utilities pay Base for capacity the same way they'd pay a small power plant — only distributed across homes. More than 200 MW of such contracts are already signed, and each one brings predictable revenue for years ahead.
- Installation pace and customer loyalty. The company currently installs about 100 batteries a day and aims to double that pace by the end of 2026. Customers rarely leave, so every new home adds revenue for the long term.
- US-made battery cells. Base still sources its cells from outside suppliers and expects to sign contracts for domestic US manufacturing by the end of 2026. An in-country supply chain of its own would make battery pricing more predictable.
- Markets outside the US. Zach Dell names the UK, Germany, and Australia as the next targets. These countries have high electricity prices and developed wholesale markets, where a virtual power plant can earn.
