Base Power, a company specializing in residential energy storage solutions, has successfully raised an additional $1 billion in Series D funding, elevating its post-money valuation to $13 billion. This substantial investment comes less than a year after the company’s previous billion-dollar funding round.
Since its inception, Base Power has installed over 500 megawatt-hours of storage capacity. Currently, the company is deploying approximately 100 batteries daily, with plans to double this rate by year’s end. This acceleration translates to about 8 megawatt-hours of storage being added to the grid each day.
In conjunction with the funding announcement, Base Power introduced its latest home battery model, the Base Core. Manufactured at the company’s Austin, Texas facility, the Base Core offers a storage capacity of 39.2 kilowatt-hours, surpassing many competitors in the market. Customers have the option to install one or two units, depending on their energy needs. Presently, Base Power operates in Texas and Illinois.
The surge in electricity demand, driven by widespread electrification and the rapid expansion of AI data centers, has placed significant strain on the U.S. electrical grid. This increased demand has been particularly evident in regions like PJM, which encompasses parts of Illinois where Base Power is active.
Unlike traditional home battery providers that require substantial upfront payments, Base Power offers a subscription-based model. For instance, in the Houston area, customers pay an installation fee of $695 for a single battery, followed by a monthly fee of $19 and an electricity rate of 13.1 cents per kilowatt-hour, aligning with regional averages. Base Power retains ownership of the batteries and sells stored electricity back to the grid during peak demand periods, generating additional revenue.
In regulated markets, Base Power collaborates with utilities to install batteries in homes, helping to alleviate local grid stress. Regardless of the market type, homeowners benefit from backup power during outages, with the nearly 40 kilowatt-hour capacity providing energy for a day or more.
The Series D funding round was led by Ribbit, Addition, Valor Equity Partners, and JPMorgan Chase’s Strategic Investment Group. Other participants included Altimeter, D1 Capital Partners, Sands Capital, Coatue, Layer Global, Energy Impact Partners, Thrive Capital, Andreessen Horowitz, Lightspeed, Trust Ventures, CapitalG, and others. Notably, Michael Dell, CEO of Dell Technologies and father of Base Power’s co-founder and CEO Zach Dell, did not participate in this round.
Base Power’s innovative approach to residential energy storage, combined with its rapid growth and substantial financial backing, positions the company as a significant player in addressing the challenges of modernizing and stabilizing the electrical grid.
