Base Power

Base Power is an Austin, Texas company founded in 2023 by Zach Dell and Justin Lopas that pairs home battery storage with retail electricity service. Rather than selling batteries outright, Base installs and owns large whole-home batteries for a low upfront fee plus a monthly membership, then provides customers a fixed-rate electricity plan; the batteries deliver automatic backup during outages and earn revenue from grid-balancing services. The company designs, manufactures, and installs its own systems and operates across deregulated Texas markets including Austin, Houston, and Dallas-Fort Worth. In October 2025 Base Power raised a $1 billion Series C led by Addition at a reported $4 billion valuation, bringing total funding to about $1.3 billion, to scale domestic battery manufacturing and expand nationally. That expansion is materializing: Base signed a 100 MW residential-storage agreement with Texas cooperative CoServ (its largest to date), is launching a 10 MW pilot with El Paso Electric in summer 2026, and started domestic manufacturing in Q1 2026 with a target of 4 GWh of annual capacity.
