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
