Long-duration energy storage (LDES) development and investment company Frontier Power USA (FPUSA) has acquired a 480MWh battery energy storage system (BESS) portfolio from developer-operator Bimergen Energy.

Announced 21 May, the portfolio is made up of three BESS projects located in Texas, US. One project is a 100MW/400MWh BESS with notices-to-proceed (NTP) expected to begin mid-2026.

FPUSA notes that two of the projects are “Texas 10’s”. It is common for developers in Texas to build 10MW projects, as projects 10MW and under are able to bypass part of the interconnection process with the Electric Reliability Council of Texas (ERCOT).
