RES has opened a flagship warehouse in Houston, Texas, to support its expanding U.S. solar and battery energy storage operations and maintenance business.
The facility will serve as RES’ primary U.S. inventory management hub, consolidating spare parts, tools, PPE, consumables, and materials for solar and BESS O&M projects. It will also support the company’s spare parts commercial offering, including vendor managed inventory, from a location that customers can visit directly.
As utility-scale solar and storage portfolios expand across the United States, local access to components is becoming increasingly tied to asset availability. A missed inverter, module, switchgear, or battery component can leave operators exposed to extended downtime, particularly when import lead times, trade policy changes, and regional demand spikes put pressure on replacement stock.
The Houston warehouse will support RES’ North American portfolio, including a 1.5 GWp O&M contract with Repsol covering major projects in Texas and New Mexico. RES has 27 years of U.S. experience and 1,300 experts across the country, managing solar, BESS, and wind assets across North America.
U.S. energy data points to another year of heavy utility-scale build-out in 2026, with solar and battery storage expected to account for most planned capacity additions. Texas remains one of the main centres of that activity, making Houston a practical base for inventory, field support, and customer-facing logistics.
“Supply-chain resilience is now a critical part of asset performance. By investing in local infrastructure, we are ensuring our customers have faster, more reliable access to the parts and expertise they need — whatever the external environment brings,” said Juan Gutiérrez, CEO of RES Services.
The warehouse also reflects a broader shift in renewables O&M, where spare parts strategy is becoming a performance discipline rather than a back-office function. Larger portfolios need better visibility over stock, standardised tooling, and stronger supplier coordination if technicians are to keep assets available across dispersed sites.
RES has constructed 19.5 GW of renewable energy projects in the U.S. to date, including the 505 MW High Lonesome Wind Project in Texas and the 690 MWdc Faraday Solar Project in Utah. The company has also commissioned a 1,200 MWh BESS project in New Mexico, described as the largest storage project in its global portfolio, with a further 4,000 MWh of storage under construction across the country.
The first phase of the Houston facility will focus on materials stocking and supply chain operations. Later phases are expected to add technical training capabilities, followed by equipment repair and refurbishment services to support renewable assets across their operating life.
