SolarMax Technology announced the signing of an engineering, procurement and construction (EPC) contract worth $127.3mn (USD127.3mn) with Longfellow BESS I LLC for a battery energy storage project in Pecos County, Texas. The contract, managed by subsidiary SolarMax Renewable Energy Provider, is scheduled for completion before the end of June 2026. The deal also includes the acquisition by SolarMax of an 8% stake in Longfellow BESS I LLC.

A major project for energy storage
The battery energy storage system (BESS) will have a capacity of 430 megawatt-hours (MWh). SolarMax will oversee the full EPC process, covering design, engineering, procurement, installation, construction, testing, commissioning, and connection to high-voltage infrastructure. The stated goal is to provide a solution that supports the stability of the Texas power grid and ensures the availability of electricity during periods of peak demand.

According to David Hsu, Chief Executive Officer of SolarMax Technology, this operation marks an important milestone in the company’s diversification towards large-scale EPC services beyond the residential sector. Supplier negotiations are in their final stages, and the company aims to meet the planned delivery deadline by mid-2026.

Commercial momentum and market outlook
The project comes amid a surge in energy storage investment in the United States, driven by growing renewable generation and the need to ensure the reliability of electric networks. The BESS device is designed to store electricity generated from renewable sources and redistribute it during high demand periods, contributing to regional energy strategies.

SolarMax reports it is actively developing new projects across the United States. According to David Hsu, the company benefits from a growing order book, supported by rising demand for large-scale energy infrastructure. The executive points out that this new focus positions SolarMax in the segment of storage solutions for the commercial and industrial market.

Commissioning of the Pecos County BESS system will be closely monitored by industry stakeholders as energy storage investment rises across the US market.
