a16z-backed Base Power is offering cheaper electricity to the power grid that needs it most
Summary
Energy storage startup Base Power recently expanded its operations into Illinois, marking its first entry into the PJM Interconnection grid territory. PJM, the largest U.S. grid operator, has faced significant challenges, including nearly doubled wholesale electricity prices and strain from new data centers, particularly in regions like Northern Virginia. Base Power, which launched two years ago in Texas, offers residential battery systems starting at 25 kilowatt-hours, requiring customers to buy electricity from them at rates 25% below utility ComEd's in Illinois. The company currently operates over 500 megawatt-hours of storage in Texas, strategically charging during low-cost periods and dispatching power when grid demand is highest. This expansion comes as PJM has been criticized for its handling of rising electricity demand, having paused new generating source applications from 2022 until April. Base Power's residential, "behind the meter" approach allows it to bypass PJM's often slow interconnection queues. The company secured a \$1 billion funding round led by Addition in October, following a \$200 million round in April 2025.
Key takeaway
For investors evaluating energy infrastructure or entrepreneurs developing grid solutions, Base Power's strategy highlights a viable path to market entry and growth. By focusing on residential, behind-the-meter battery deployments, you can circumvent slow utility interconnection queues and directly address critical grid demand issues. This approach offers a competitive advantage, enabling rapid deployment and potentially higher returns in strained markets like PJM Interconnection. Consider models that integrate distributed resources to capitalize on grid vulnerabilities and offer direct consumer value.
