GVEC and Base Power Expand Texas Distributed Battery Program

Guadalupe Valley Electric Cooperative (GVEC) and Base Power Company announced a 50 MW expansion of their distributed battery program across GVEC’s entire service territory, up from a 2 MW pilot, on April 13, 2026.

What Was Announced

The expanded program will deploy 25 kWh whole-home battery systems at GVEC member residences. GVEC members will pay $295 for single systems or $445 for dual systems for installation, which the utility states is more than 50% below standard residential battery pricing.

Deployment is slated to bring 20 MW online by the end of 2026, with an additional 15 to 20 MW to be added annually thereafter. Base Power, headquartered in Austin, Texas, is managing the deployment across GVEC’s 3,500 square mile service territory east of San Antonio, which encompasses approximately 100,000 customer meters.

Why It Matters

This 50 MW aggregation is comparable in size to GVEC’s typical wholesale power purchases, which are often in 50-100 MW increments. This positions the residential battery fleet as a significant supplier, on par with GVEC’s other wholesale energy providers. The aggregation participates in ERCOT’s Aggregated Distributed Energy Resource (ADER) Pilot Program, enabling the fleet to bid into ERCOT’s wholesale energy and ancillary services markets.

Base Power claims its pricing is 95% cheaper than similar backup power options, according to a Utility Dive interview with the company’s CEO. The actionable takeaway is that this program aims to reduce demand charges for GVEC members while providing grid services to ERCOT.

Critical Perspective

Given the aggressive deployment schedule of 15-20 MW per year after 2026, what is the plan to ensure sufficient supply chain capacity and skilled labor for battery installation and interconnection across GVEC’s extensive territory to meet these targets without significant delays?
