A step towards carbon-neutral energy production
Vantaa Energy will build a waste-to-energy plant on its own site at the junction of Ring Road III and Porvoonväylä motorway in Långmossebergen in Eastern Vantaa. The plant will meet stringent environmental requirements. The construction work started in 2011, and the plant will be taken into use in 2014 according to a preliminary schedule.
The power plant will produce both electricity and heat. Heat production will amount to approx. 920 gigawatt-hours (GWh) and electricity to 600 GWh a year. The heat production will correspond to about half of Vantaa’s annual heat requirement. The fuel used in the plant will be source-separated mixed waste. The waste will be combusted with grate-fired technology, which is a reliable and the most widely used waste combustion technology in the world. In connection with the plant, there will also be a separate gas turbine plant, the flue gases of which will increase the energy efficiency of the plant.
The new waste-to-energy plant will replace one of the Martinlaakso power plant’s production units, which will come to the end of its service life by 2015 at the latest. The waste-to-energy plant will also contribute to the mitigation of climate change as it will reduce the use of coal and the amount of mixed waste ending up in the landfill. Consequently, Vantaa Energy will use about 30 per cent less coal in electricity and heat production. The company’s overall emissions will also fall by some 20 per cent from the present level. The project will also provide new jobs in the region.
