Technology group Wärtsilä has secured a 452MW equipment order and a long-term operation and maintenance (O&M) agreement for the Pecos Power Plant in Pecos, West Texas, a project owned by Mercuria Americas and Continental Resources.

The plant is designed to provide flexible, dispatchable generation to support grid reliability for the Electric Reliability Council of Texas (ERCOT) as renewable power grows.

The project has been built up in stages, with Wärtsilä booking an initial 226MW order in the first quarter of 2025 (Q1 2025), adding another 226MW in Q3 2025 and signing the O&M agreement in Q4 2025. The facility will use 24 Wärtsilä 1850SG reciprocating engines and is expected to enter commercial operation in 2027.

Peak Reliability, a Mercuria company, led the development of the plant in collaboration with Wärtsilä. The companies say the project is intended to deliver reliable, efficient power to a region seeing record demand, while also supporting local industry and businesses with lower-cost dispatchable supply.

Wärtsilä said the deal reinforces its role as a life cycle partner for independent power producers, with the O&M contract covering the full buildout and long-term performance of the plant.
