About Base Power

The grid is the largest, most complex machine in the world. But it’s aging, struggling to keep up with today’s demand, and is unprepared for our electrified future. Base is modernizing the grid as the first engineering-led, technology-driven power company. We’re deploying a nationwide network of distributed batteries that strengthens critical infrastructure and saves Americans money.
