78.4 kWh Home Battery Backs Power Grid, Installs in Under an Hour
U.S. battery installs rose 32% in the first quarter of 2026 as falling costs and data-center demand made storage the fastest way to add capacity.
- Austin-Based Base Power raised $1 billion in Series D funding, valuing the company at $13 billion, to scale its new Base Core home battery system.
- Rising electricity demand from AI data centers and economy-wide electrification has strained the U.S. electrical grid, as utilities struggle to build large-scale generation projects quickly enough to keep pace.
- Base Core offers 39.2 kWh of capacity and installs in under an hour, while the company charges $695 for installation and $19 monthly, retaining ownership to operate units as distributed resources.
- Currently operating in Texas and Illinois, Base has secured utility partnerships with El Paso Electric, Austin Energy, and CoServ covering more than 200 MW of capacity.
- By connecting thousands of home batteries into a virtual power plant, Base aims to allow the grid to tap into residential storage during peak demand periods, addressing supply constraints.
