Capstone Energy+ Inc. (Capstone), a provider of behind-the-meter gas turbine energy solutions for industrial and commercial operations, has delivered two C1000S Signature Series gas turbines to support the continued expansion of a US midstream natural gas infrastructure project in southern New Mexico. The 2 MW order represents the latest phase of a multi-year program and expands the customer’s fleet to a total of 12 Capstone C1000S gas turbine systems, providing 12 MW of power generation operating across six interconnected gas facilities.
The project supports one of the largest sour-gas gathering and treatment networks in the Delaware Basin, spanning more than 200,000 acres (80,937 ha) and over 200 miles (320 km) of gathering pipelines in Lea County, New Mexico. The system was developed by Northwind Midstream, which was acquired by MPLX LP in 2025, and is designed to gather, compress, and treat natural gas containing elevated levels of hydrogen sulfide and carbon dioxide (see MPLX Acquires Northwind Midstream | Gas Compression Magazine). With utility power unavailable at several remote compressor stations, the customer required a rapidly deployable distributed power solution capable of supporting critical operations, meeting stringent emissions and uptime reliability requirements in remote, high-altitude environments subject to extreme seasonal temperature changes.
The deployment began in 2024 with an initial rental fleet of eight C1000S gas turbine systems. Following the project’s successful performance, the client expanded the deployment in 2025 with the purchase of two C1000S systems. In 2026, the client exercised its option to purchase the original eight rental units as permanent assets and further expanded the project with the acquisition of two additional C1000S gas turbine systems, bringing the total fleet to 12 C1000S units.
The expansion comes as operators across the Permian Basin face growing demand for infrastructure capable of handling off-spec gas streams. Northwind recently expanded its network with additional treating capacity, compressor stations, and acid-gas injection wells. The system currently includes more than 200 miles of NACE-standard pipeline, five compressor stations, and 150 MMcf/d (4.2 x 106 m3/d) of sour-gas treating capacity at the Titan Treating Complex.
