GridStor has commissioned its first operational project in Texas with the completion of the Hidden Lakes Reliability Project, a battery-based electricity storage facility with a capacity of 220 megawatts (MW) and 440 megawatt-hours (MWh). The system is designed to supply energy to approximately 140,000 Texas households during peak consumption hours.
A response to grid pressure
The project is integrated into the market operated by the Electric Reliability Council of Texas (ERCOT), which oversees grid stability across most of the state. GridStor stated that the facility will play a key role in addressing the rising demand driven by urban expansion, the growth of data centres, and industrial development.
GridStor Chief Executive Officer Chris Taylor said the company aims to deliver a fast-track solution to the strain placed on Texas power infrastructure. According to the company, the facility will help limit wholesale market fluctuations and contain costs for consumers during periods of peak demand.
Fiscal impact and local employment
The project is expected to generate several tens of millions of dollars in tax revenue for local authorities, including sales, use, and property taxes benefiting Galveston County and Dickinson Independent School District. Around 100 people, primarily from skilled trades, were employed during the construction phase of the facility.
GridStor, backed by Goldman Sachs Asset Management, manages a storage project pipeline exceeding 3 gigawatts (GW) currently under development or construction across the United States. The company targets high-growth markets with solutions tailored for infrastructure operators, data centres, and industrial clients requiring rapid electricity access.
