Ostroleka C is a 1GW ultra super critical coal-fired power project under development at Ostroleka, in north-east Poland.

The coal-based thermal power plant will be owned and operated by Elektrownia Ostroleka,  a special-purpose 50:50 joint venture between two Polish state-run utilities, Energa and Enea.

The engineering, procurement and construction (EPC) contract for the plant was signed in July 2018.

Construction on the $1.6bn project is expected to begin by the end of 2018.

Scheduled to commence operation in 2023, the Ostroleka C power plant is  expected to produce 7,200GWh of electricity a year, which will be enough to power 300,000 Polish homes.

Ostroleka C power project development history

In 2009, Energa, the owner and operator of Ostroleka A and Ostroleka B power plants, established Elektrownia Ostroleka to build the 1,000MW Ostroleka C power plant and started preparatory works with the aim of bringing the new plant into operation by 2012.

The project was, however, cancelled in late-2012, due to lack of financing.

The Ostroleka C project development kick started in the second half of 2016 after Energa and Enea entered a joint investment agreement for the project, with Enea buying 50% interest in Elektrownia Ostroleka.

The project received permits from the Polish government in July 2016.

Ostroleka C power plant make-up

Located on a site adjacent to Ostroleka A and B power plants on the border of the Rzekuń Commune and the City of Ostroleka, the new 1,000MW power plant will consist of an ultra super critical boiler and a steam turbine generator supplied by GE.

The plant will use hard coal as primary fuel and biomass as secondary fuel.

Ostroleka C will have a closed cooling system consisting of cooling towers, and use water from the Narew River for cooling.

With net power efficiency exceeding 46%, Ostroleka C will be one of the most efficient thermal power plants in Poland.

The plant will also be fitted with all necessary emission control equipments to meet the European Union’s (EU) strict emission standards applicable for large combustion plants (LCPs).

Coal supply for Ostroleka C

Ostroleka C power plant will be supplied with coal from Bogdanka coal mines located in the Lublin Coal Basin, approximately 273.4km away from the project site, under long-term coal supply agreements with Polska Grupa Górnicza (PPG) and Lubelski Węglem Bogdanka. Enea owns a majority stake in Bogdanka mines.

PPG agreed to supply up to two million tonnes of coal a year for Ostroleka C and one million tonne of coal a year for Ostroleka B, under a long-term agreement signed in 2016.

Power transmission from Ostroleka C

The electricity generated by the power plant will be evacuated by the state-owned transmission company Polskie Sieci Elektroenergetyczne Operator (PSE) via 400kV transmission lines connected the Grudziądz Węgrowo substation.

Contractors involved

GE Power signed the EPC for the Ostroleka C power plant in July 2018. The company will design and build the power plant as well as provide the boiler and turbine generator, under the contract agreement.

Polimex-Mostostal, an engineering and construction company based in Poland, was selected as the subcontractor by GE Power for the plant construction as well as for the delivery and assembly of steel structures for Ostroleka C project, in June 2018.

Ostroleka A and B plant details

Ostroleka A coal-fired power plant, built in 1956 with an initial installed capacity of 78MW and later upgraded to 390MW, was decommissioned in 2014.

Ostroleka B, comprising three 200MW coal-fired generating units, was commissioned in 1972. The power plant has been undergoing a comprehensive modernisation programme since 2015.

The modernisation programme involved the replacement of three OP-650 boiler units supplied by Refako and the refurbishment of turbine generator units, to increase the total generating capacity of the plant to 681MW, while decreasing Knox emissions.

Further, the switchgears and transformers were refurbished and the flue-gas desulfurisation (FGD) technology was installed.

A contract agreement was signed with Refako and Energy Serwis Spolka to construct the second FGD unit for Ostroleka B, in July 2018.
