Banpu Power and Energy Vault buy in Texas
Thailand-based power firm Banpu Power (BPP) has acquired the Megamouth BESS project in the ERCOT, Texas, market. The 100MW/200MWh project in Houston needs US$90 million of investment to be completed for a commercial operation date in Q4 2027.
It benefits from a 40% investment tax credit (ITC), which was maintained by the Trump administration amidst a phase-out of tax credits for wind and solar. The Megamouth project seller was developer Grid Connected Infrastructure.
In similar news, Energy Vault has acquired a 175MW/350MWh BESS in Texas, called McMurtre, from developer Belltown Power. The project still needs to reach ready-to-build (RTB) stage, and is expected to do so in Q4 2026, for commercial operation in December 2027.
It has a Small Generator Interconnection Agreement (SGIA) and full site control, providing a clear and de-risked path to construction, Energy Vault said. The firm is considering multiple ‘investment-grade’ offtakers for its capacity.
The company, which initially started out as a gravity energy storage tech firm but has transitioned into both BESS and green hydrogen and BESS owner-operation, released its full-year results recently.
