Foss & Company has closed a $58 million tax equity investment for a battery energy storage system located in Texas. This funding leverages tax equity structures enabled by the Inflation Reduction Act to support energy projects across the state.
Why it matters
Battery energy storage systems provide essential grid stability and offer increased resilience against regional weather risks like windstorms and hail. This investment reflects a broader shift toward diversifying energy portfolios to improve reliability for Texas households.
The $58 million investment supports a grid-scale battery project in Hidalgo County. This follows a $220 million financing package secured in September 2026 for a separate 100MW, 400MWh battery project in Arizona.
