Wärtsilä will build a 43MW gas-engine power plant for EPV Energy at the existing Mertaniemi site in Lappeenranta, Finland.
The engineering, procurement and construction contract, announced on 12 November and booked in the fourth quarter, also includes a six-year service agreement. The companies did not disclose a contract value.
Four Wärtsilä 34SG engines will provide generation that can respond to changing electricity demand and variable renewable output. Full operation is scheduled for the first half of 2029.
The engines will initially burn natural gas. Wärtsilä says biogas and synthetic renewable gases are intended to be introduced gradually when sufficiently available; the plant is therefore not being presented as renewable-fuelled from its first day.
Services cover maintenance planning, operational support, predictive maintenance, spare parts and control-system updates. This is EPV’s second project under its balancing-power programme, following Tornio, which began operating in April 2026.
