The Opole power plant located approximately 100km away from Katowice, Poland, is undergoing a major expansion to add two 900MW ultra-supercritical (USC) generating units.

Named Opole II, the PLN11.6bn ($3bn) expansion project is currently the biggest coal power project under construction in Europe and represents Poland’s biggest energy infrastructure investment in the last 29 years. It is set to make Opole one of the biggest energy facilities in Poland.

PGE Elektrownia Opole, a subsidiary of state-owned Polska Grupa Energetyczna (PGE), owns and operates the Opole power plant.

The plant has been in production since 1993 and has a generation capacity of 1,532MW. The capacity will be increased to 3,332MW by adding two new coal-fired units five and six by 2019.

The two new units are together expected to generate 13.4TWh of electricity a year, which will be enough to power two million Polish households.

Construction on the expansion project started in February 2014. The expanded power station is expected to account for more than 10% of the country’s total installed capacity.

Opole II project development history

PGE Elektrownia Opole called for tenders for the construction of units five and six  in December 2009 and received preliminary offers from potential contractors in September 2010.

The general contractor agreement for the expansion project was signed with a consortium of three companies in February 2012.

The project was approved for construction in January 2014.

Opole power plant units five and six details

Each new generating unit of the Opole power plant is being equipped with an ultra-supercritical boiler and a steam turbine generator supplied by GE. Each boiler will have a height of approximately 125m.

The units five and six will use a closed cooling system consisting of 185m-high cooling towers.

Technology

Fitted with GE’s advanced ultra-supercritical technology, the two new units will be able to obtain a net energy efficiency of 46% and emit 20% lesser CO2 compared to conventional coal-fired power plants.

The units can be adapted for installation of CO2 capture facilities in future.

The new units are also being equipped with all necessary emission control mechanisms to comply with the European Union’s (EU)  stringent emissions regulation for sulfur dioxide, nitrogen oxides, and particulate matter.

The estimated operational life of the units is 35 years.

Coal supply for Opole II power plant

The 1,800MW Opole II will require approximately 4.1 million tons (Mt) of hard coal a year, which will be supplied by Kompania Weglowa under a long-term agreement signed in June 2013.

Power transmission from the Opole power plant

PGE Elektrownia Opole signed an agreement with state-owned transmission system operator   Polskie Sieci Elektroenergetyczne (PSE) for connecting the new units of the power plant with the Polish national grid, in March 2010.

The electricity generated from the units will be transmitted first to the existing 400kV distribution substation at Dobrzeń and further via a single-circuit 400kV line connecting Pasikurowice and a double-circuit 400kV line connecting Wrocław.

The transmission infrastructure for the new power generating units includes total 3,000km of power cable and upgrade of the Dobrzeń distribution substation with a new transformer unit and feeder bays.

Financing for the Opole power plant expansion

The Opole II expansion project is underwritten by a group of four European insurers including Europe ’s biggest insurer Allianz, Italy’s Generali, Germany’s Munich Re, and Polish insurer PZU.

Contractors involved with Opole power plant expansion

The engineering, procurement, and construction (EPC) contract for the two new generation units at Opole power plant was awarded to a  consortium of Rafako, Polimex-Mostostal, and Mostostal Warszawa in February 2012.

Alstom (now GE Power) was subcontracted by the EPC consortium for the USC technology along with major equipment for the new generating units in January 2014.

As part of the subcontract valued approximately $1.25bn, GE will provide its efficient USC technology along with the boilers, turbines, generators, air quality control systems as well as the balance of plant for units five and six of the Opole power plant.

The new turbines and generators were designed and manufactured at GE Power’s Elbląg factory in Poland. GE is also responsible for overall project management.

GE subcontracted Finow Rohrsysteme for the pre-fabrication of external high-pressure piping systems for the new units.

GEDA provided lift solutions during the construction of cooling towers for the new plant.

ABB was selected for the supply, installation and commissioning of seven single-phase transformers, four three-phase multi-tap transformers, and two three-phase back-up transformers in September 2015.

Opole power plant make-up

Built on a 290ha site, the Opole power plant comprises four operational units, with a combined installed capacity of 1,492MW, including one 376MW, two 373MW units, and one 370MW commissioned between 1993 and 1997.

The plant is equipped with four once-through BP-1150 boilers from Rafako.

The power station achieved 1,532MW generating capacity following upgrade and modernization of the existing units.
