Base Power will manage system installation and ongoing maintenance. For homeowners with existing solar setups, Base can connect the battery to be powered either by the homeowner’s solar system or the grid, based on availability.
In October 2025, Base Power raised US$1 billion in Series C financing from venture capital fund Addition. The company has also qualified for Texas’s Aggregated Distributed Energy Resource (ADER) programme, enabling distributed batteries to be combined and bid directly into the grid.
In February, Base Power announced a residential DER pilot programme with utility El Paso Electric Company (EPE).
Similar to the CoServ programme, the batteries will be installed at qualifying residential customer homes and integrated into EPE’s system to provide grid services during peak demand periods, while also maintaining backup power for customers during outages.
The partnership was selected through EPE’s Residential Distributed Energy Storage Pilot Programme (DESPP), which aims to deploy up to 10MW of residential energy storage ahead of the 2026 summer peak.
Base Power’s ‘Gen 1’ battery has an 11.4kW/25kWh capacity and has UL 1973, UL 1741, UL 9540, and UL 9540A certifications.
Notably, the company claimed that the CoServ programme marks Base’s fifth utility collaboration in Texas, which it hopes to use as a proven model for rapidly deploying storage capacity.
