Enefit Green uses biomass for electricity and heat production in the Paide power plant in Estonia and in the Valka and Broceni power plant in Latvia. The biomass is produced from low-quality timber or bush that is not suitable for the wood or paper industry. Residues from the wood industry are also used.
The environmental friendliness of the use of biomass and the large volume of local reserves make biomass a very important and high-potential renewable energy resource for Estonia and Latvia.
It is also an alternative to energy production from non-renewable sources. The efficient use of biomass has a central spot in the renewable energy sector from the energy independence perspective.
Enefit Green’s Paide Power Plant produces both heat and electricity. The heat is sold to the residents of Paide and the electricity is sold to the grid. Enefit Green’s power plant in Paide uses biomass as fuel, which is mainly supplied by the local forestry and timber industries.
It produces about 75% of the annual heat requirement of Paide and about one-fifth of its electricity consumption.
The plant has an electricity production capacity of 2 megawatts and a heat production capacity of 8 megawatts. Up to 7.5 gigawatt-hours of electricity is generated annually, covering the annual electricity demand of 2,500 average households, and up to 42 gigawatt-hours of heat.
Enefit Green's Valka Power Plant produces heat for the city of Valka and sells the produced electricity to the Latvian grid. The plant uses biomass as fuel, which is supplied by nearby wood chip companies.
Eesti Energia, the owner of Enefit Green, acquired a majority holding in the Valka heat company in January 2011 and became its sole owner at the end of 2016. In 2012, a biofuel-powered plant was built to supply heat to the city of Valka.
The electrical capacity of the power plant in Valka is 2.4 megawatts and its heat production capacity is 8 megawatts. The annual electricity output is 14.3 gigawatt-hours, covering the annual electricity demand of 4,767 average-consumption households. The plant’s annual heat output is up to 23.3 gigawatt-hours.
Enefit Green owns a CHP plant in Broceni, Latvia, where heat and electricity is produced from wood chips.
The plant's annual electricity output is 33.3 gigawatt-hours that is sold to the Latvian grid and covers the annual electricity needs of 11,100 average-consumption households.
Its annual heat output is 125 gigawatt-hours that is supplied to the pellet plant complex.
