Our projects making a difference

Lamesa II solar farm

Lamesa II solar farm is a 50MW solar farm located in Dawson, Texas. The construction of the project was performed by RES and funded by OCI Solar Power, the then owner. RES completed construction of the project in late 2018. The project was then sold to D E Shaw Renewable Investments (DESRI) in October of 2018. The project was constructed as part of a Power Purchase Agreement between the City of San Antonio’s CPS Energy and OCI Solar. Lamesa II also includes a substation that sits adjacent to the 102MW RES constructed and operated Lamesa I solar farm, which RES sold to Southern Power in 2016.

CPS Energy Solar + Storage

In 2018 RES started the construction of its first storage project in Texas - a solar + energy storage system for CPS Energy (CPS) in San Antonio. The project consists of 5MW of distributed solar capacity co-located with a 10 MW/10 MW lithium-ion Battery Energy Storage System (BESS) at Southwest Research Institute’s (SwRI) facility in West San Antonio. The project is a major step for CPS Energy in using new technology to produce emissions-free renewable energy. Both the solar and storage installations are owned by CPS and provide their teams with direct experience owning and operating these technologies within their service territory. BESS asset management services are performed by RES. Additionally, RES provides smaller solar and storage projects at the same facility to support SwRI’s research initiatives.
