6 March 2007Role of DER in EU and in the Baltic StatesYlo Rudi 10 The Environmental Requirements Influencing on Operation of Oil Shale Fired Power Plants – SO 2 bounding on existing boilers > 65%, – fly ash emissions < 200 mg/Nm – to reconstruct ash handling systems, and bring ash landfills in compliance with landfill directive – SO 2 emissions total < ton/year The current SO 2 annual emission rate is about tons/year. The new CFB based capacity will be erected – LCP directive requirements will apply to all boilers

Increase in the use of renewables –Indicative target 5,1% of power by 2010 (2001-0,1%; ,1%). –Main emphasise on the biofuels based CHP generation and windpower. Strategic Energy Policy Objectives (1)

6 March 2007Role of DER in EU and in the Baltic StatesYlo Rudi 12 Increase in the use of CHP-s –Indicative objective 20% of power from CHP-s by 2020 (today 10%). Efficiency Improvements: –Primary Energy Consumption shall not exceed until 2010 the level of Strategic Energy Policy Objectives (2)

(Planed 7.34 euro cents per kWh since 01July 2007)

6 March 2007Role of DER in EU and in the Baltic StatesYlo Rudi 18 CONCLUSIONS In Estonia wind and biomass resources are significant. If the "right" policies were in place, wind and CHP with biomass could make an important contribution to Estonia's energy supplies. The development of distributed generation needs the renovation of the transmission and distribution grids. The change of electricity generation technology needs a good level research.
