Metso supplies CHP systems to Baltics pellet plants

By Lisa Gibson | March 24, 2011

Expanding its portfolio, Metso will supply AS Graanul Invest, the largest pellet producer in the Baltics, with biomass combined-heat-and-power systems at two of its six pellet mills.

The plants, one at AS Graanul Invest’s Latvian location, SIA Graanul Invest, and one at its Estonia location, Oü Helme Energia, both will produce 15 megawatts (MW) of heat and 6.4 MW of power. The pellet mills will use a portion of the output, but the majority will be sold to the national grids, according to Metso. Besides being the largest pellet producer in the Baltics, AS Graanul Invest is also among the top three European pellet producers.

Metso also recently provided equipment for a 50 MW Dalkia power plant in Facture, France, that was just commissioned this month, as well as another CHP plant for Porvoon Energia in Finland. The Finland plant will produce 38 MW of district heat to the southern coast city of Porvoo, along with 12 MW of electricity for the national grid.

The €15 million ($21.2 million) Latvian and Estonian power plants will be delivered by the Metso-Wärtsilä joint venture MW Power and will include plant automation systems, according to Metso. They will use the same bubbling fluidized bed technology and a combination of forest residues such as bark and wood chips or milled peat as feedstock.

Metso is a global supplier of sustainable technology services for mining, construction, power generation, automation, recycling and pulp and paper industries, and Wärtsilä provides complete life-cycle power solutions for the marine and energy markets. Their joint venture, MW Power, provides medium- and small-scale power and heating solutions.
