December 12, 2025 [Pipeline & Gas Journal]- Trinity Gas Storage LLC has reached a final investment decision (FID) on Phase II of its natural gas storage expansion in East Texas, a move that will add 13 billion cubic feet (Bcf) of new capacity and strengthen the state’s grid reliability and gas market flexibility.

The project is being financed through a new credit facility led by Deutsche Bank AG, New York Branch, and Société Générale as joint lead arrangers and bookrunners, with BankUnited serving as depository bank.

“Reaching FID on Phase II is a clear endorsement of the strength of Trinity’s asset, our execution capabilities, and the compelling fundamentals underpinning the Texas energy market,” said Jim Goetz, CEO of Trinity Gas Storage. “The support of Deutsche Bank, Société Générale, and BankUnited reflects deep lender confidence in this project and its importance to grid reliability.”

Phase II will add at least 13 Bcf of incremental working gas capacity and include two new pipeline interconnects, expanding Trinity’s ability to serve power generators, utilities, and producers across Texas. The expansion is scheduled to enter service by August 1, 2026.

“Building on the successful delivery of Phase I, this expansion will meaningfully increase capacity and deliverability at a time when secure and flexible natural gas infrastructure is more critical than ever,” Goetz added.

The development is part of Trinity’s long-term strategy to support Texas’ fast-growing power demand — driven by large-scale data centers, AI-related energy loads, and weather-driven volatility. The added storage capacity will help ensure reliable, dispatchable energy during peak periods and supply disruptions.
