Dåva CHP

Opportunities enabled:

Dåva CHP is one of the world's most energy efficient and environmentally friendly plants with waste as its main fuel. Here we produce district heating and electricity from sorted waste and residues from the forest industry.

Dåva CHP Dåva cogeneration plant is located at Dåvamyrans industrial landfill, about 9 km northeast of Umeå Centre. The plant has an effect of 55 megawatts of heat and 10 megawatts of electricity. District cooling is also produced here. Incineration capacity is 20 tons per hour and waste is the primary fuel. Production takes place in a way that is gentle on the environment and minimizes emissions through a highly advanced filtration system. The owner of the plant is the municipal company Umeå Energi. Dåva 1 Every year, the facility receive numerous visits. Both school classes, industry workers, ministers and international delegations come here to learn more about the facility and take advantage of our unique expertise in the area of waste. Extracts heat and electricity Both heat and electricity is extracted in the plant and heat is also recovered from the flue gases. The heat produced here can heat about 18 000 normal houses for a whole year. Gross production of electricity is enough to support approximately 6,500 homes with electricity. Facts Dåva 1 Starting year: Year 2000. Effect: 65 MW (55 MW district heating + electricity 10 MW). Fuels: Household and industrial waste, forest residues. Incineration capacity: 20 tons / h (equivalent to approximately 65 MW). Degree of purification: Acidified gases 99.5 percent. Particle-bound contaminants 99.5 percent. Dåva 2 Dåva 2 meets the increased demand for district heating. Umeå is growing rapidly at the same time as district heating has become the natural first choice for new buildings, both large and small. Another reason for the focus on Dåva 2 is the environment. The new facility dramatically reduces the amount of oil in Umeå Energi´s fuel mix, and with the advent of the new plant, both environmental performance as well as security of supply in the overall heat production is improved. Double capacity The Dåva facilities produce both heat and electricity, a total of 170 MW. That makes Dåva northern Sweden´s largest cogeneration plant based on solid fuels. In Dåva 2, biofuels such as logging residues, wood chips, bark, sawdust and peat is used as fuels. These fuels are mainly from the region, contributing to employment in the forestry and transport sectors in northern Sweden. Facts Dåva 2 Starting year: 2010. Effect: 105 MW (75 MW district heating + electricity 30 MW). Fuels: Biofuel. Type of boiler: Fluid Bed Boiler. Boiler efficiency: 88 to 89 percent. Overall efficiency: 95 percent (including condensation). Town: Umeå Find us: Dåva Energiväg 10 Website: (swedish) Visiting: All year Duration: 1,5-2 hours Languages: Swedish & English
