Wärtsilä secured a contract to supply 452MW of power generation equipment and signed a long-term operation and maintenance agreement for the Pecos Power Plant in Texas.
The plant belongs to Mercuria Americas and Continental Resources.
The project is located in Pecos, Texas. It will provide flexible power generation to support grid reliability as renewable energy penetration increases.
Wärtsilä booked an initial 226MW order in the first quarter of 2025.
The company expanded the order by another 226MW in the third quarter of 2025.
The partners signed the long-term O&M agreement in the fourth quarter of 2025.
Peak Reliability, a Mercuria company, developed the project together with Wärtsilä.
The power plant will use 24 Wärtsilä 1850SG reciprocating engines.
The facility aims to meet rising electricity demand in West Texas.
“The flexibility of Wärtsilä’s technology will allow us to maximize our operational efficiency in an increasingly volatile power market,” said Martin Parizek, Managing Director of Peak Reliability.
He added that the region faces record electricity demand and that the project will strengthen power supply reliability.
The natural gas-fired facility will deliver dispatchable energy into the ERCOT market.
The plant sits in one of the world’s largest renewable energy regions.
The project will also support industrial operations and businesses across West Texas with low-cost and reliable power.
“Wärtsilä understands the pressing need to meet growing power demand with solutions that support energy supply, reliability and sustainability,” said Risto Paldanius, Vice President Americas at Wärtsilä Energy.
He said Wärtsilä’s end-to-end delivery model reduces project risk and shortens time to market.
Under the agreement, Wärtsilä will manage long-term plant performance, availability and reliability.
The company said the project strengthens its position as a lifecycle partner for large-scale independent power producers.
Commercial operations are expected to start in 2027.
