Wärtsilä of Finland Wins EPC Order for 43MW Gas Power Plant

en.Wedoany.com Reported - On November 12, Finland's Wärtsilä announced that it had won an order from Finnish energy company EPV Energia for a 43MW gas engine power plant project. The new facility will be built at the existing Mertaniemi power plant site in Lappeenranta, Finland, and will be covered by a six-year operation and maintenance service agreement. The project adopts an engineering, procurement and construction (EPC) turnkey model, is equipped with 4 Wärtsilä 34SG gas engines, and is scheduled to be fully operational in the first half of 2029.

The new power plant is the second project under EPV Energia's balancing power plan and will primarily undertake grid peak-shaving and fast regulation tasks. The units will start or shut down according to changes in electricity demand, providing dispatchable power during peak consumption periods, grid disturbances, and when wind and solar output is insufficient. The project utilizes the existing power plant site and infrastructure at Mertaniemi, reducing the need to build additional site support facilities.

The power plant will initially use natural gas as fuel, and the engine system is designed to be capable of converting to low-carbon and sustainable fuels. As fuel supply conditions mature, EPV Energia plans to gradually introduce biogas and synthetic renewable gases.

The six-year service agreement is supported by Wärtsilä's specialized service center, with scope covering maintenance planning and coordination, operational technical support, predictive maintenance based on digital analytics, as well as spare parts, on-site services, and control system software patch updates. Wärtsilä will support unit operation through remote data analysis and maintenance coordination, with the service coverage period aligned with the operation and maintenance arrangements after the plant is commissioned.

This project is the second gas engine power plant under EPV Energia's balancing power plan. The first project is located in Tornio, Finland, with an installed capacity of 43MW, and was commissioned in April 2026. Both power plants use Wärtsilä gas engines and supporting service agreements.
