Pöyry Oyj (HEL:POY1V) PÖYRY PLC Press release 1 December 2008 at 2.30 p.m.

PÖYRY AWARDED POWER PLANT IMPLEMENTATION ENGINEERING BY STORA ENSO IN POLAND

Pöyry has been awarded implementation engineering services by Stora Enso Oyj for a combined heat and power plant project in Poland. The value of the contracts is totally about EUR 3.3 million.

Stora Enso is investing EUR 137 million in building a new power plant at the Ostroleka Mill site in Poland. The power plant project is scheduled to start immediately and to be completed in the third quarter of 2010.

The new power plant, which will be able to use multiple fuels, will improve Ostroleka Mill's energy self-sufficiency and energy efficiency, thereby reducing carbon dioxide emissions. The aim is to increase the biofuel usage depending on its availability. With the new power plant, the self-sufficiency of the mill will be about 65% in electricity and 100% in steam production. The power plant investment will further improve the cost competitiveness of Stora Enso's operations in Poland. Ostroleka Mill does not currently have its own power plant.

Pöyry's contracts cover implementation engineering services for the new power plant. The assignments support Pöyry's position as a market leader of comprehensive engineering and project services to both forest and energy industries.

Pöyry is a global consulting and engineering firm focusing on the energy, forest industry and infrastructure & environment sectors. Pöyry's net sales in 2007 amounted to about EUR 720 million and it employs 8000 experts.
