Polish utility Energa will upgrade a 230MW coal-fired unit to co-fire with wood pellets at its 690MW Ostroleka power plant, increasing wood pellet burn in the unit from 2026 onwards.
The upgrade to the 230MW unit — located in northwest Poland — is expected to be completed in the fourth quarter of 2025.
The upgrade at the unit — one of three — will reduce its emissions to meet the 550g of CO2/kWh cap, Energa said today. Meeting this limit will enable the unit to receive capacity market payments awarded to the unit over 2026-31, as noted in the contract signed with the Polish grid operator.
Energa expects to consume 200,000-350,000 t/yr of industrial wood pellets from 2026.
Polish oil company Orlen is a majority shareholder in Energa.
Energa is one of two large Polish utilities upgrading their coal generation units to allow increased wood pellet co-firing from 2026. Government-controlled Enea is upgrading its coal units at its 1.4GW Polaniec power plant to enable them to co-fire with wood pellets to reduce their emissions and meet the 550g of CO2/kWh cap. After this upgrade, the Polaniec plant, which also operates a dedicated biomass-fired 225MW unit, might increase its biomass consumption to as much as 2.5mn t/yr, Enea said last year.
