Project ExpectationsVery high efficiency
Production of the renewable energy/electricity up to 180GWh/year
Very efficient reduction of the CO2 emission
Power and heat cogeneration all year round
Alternative supplier of the heat. Decreasing the dependence onnatural gas. Increasing the reliability of the DH network.Decreasing the natural gas import
Decentralization of the power generation and positive impact tothe reliability of the electrical system
Valuation of the low quality forests. Increasing the employment inrural areas
Decreasing the water use and oil shale combustion in Narvapowerplants
Gentrification one of the most awful areas in Tallinn

Fuel supply - social and environmental impacts
Biofuels reduce greenhouse gasemissions in comparison to fossil fuels
Increasing stable demand of biofuelscaused a boom on biofuel market .
More value is added to forestry sector
Additional investments are made intowood processing equipment
This has encouraged new supportschemes for forest and agriculureentrepreneurs
Created new jobs and contributed toregional and rural development
