  1. BIOENAREA regional examples Transition from fossil fuels to biofuels - Town of Elva district heating network Martin Kikas, Jaanus Uiga Tartu Regional Energy Agency Case study done by project Woodenergy Kozani, 21 of November 2012

  2. District Heating in Estonia • 60% of thepopulationused DH • 70% of heatenergy consumption in DH • 151 out of 226 local municipalities • 287 boiler houses • >1447 km of DH pipeline • Natural gas 44% • Woodfuels 25% • Data 2010, AccordingtoNational Audit Office Estonia • and Statistics Estonia

  3. District Heating in Estonia Average price of MW·h of heat 60 €/(MW·h) Median price of MW·h of heat 74,5 €/(MW·h) For smaller companies – 70% of costs is made on fuels (natural gas; shale oil)* Data from august 2012 *Estonian Competition Authority. Aastaraamat 2011.

  4. District Heating in Elva • Managed by OÜ Elva Soojus • Shares 100% owned by town of Elva • One DH network divided between 3 grids • Nooruse • Kirde • Haigla

  5. DH in Elva: Boiler Houses * only used when it’s not the usual heating period

  6. DH in Elva: Distributing Network * Calculatedfrom the hourly temperature data of 2010, that has been normalized using base degree days ** For the Kesklinna heating network, the actual full year data was not available, therefore the estimated values are used.

  7. DH in Elva: Energy Production 2010

  8. Road to efficiency…Major investments

  9. MajorInvestments: Conclusions • 197,9 EUR per kW ofbiomass-fired boiler heatpoweroutput • 205,3 EUR per m of DH dualpipeline • 27,5 EUR per m2of net heatedsurface * The standard expenditures were not taken into account

  10. Conclusions, price 52,28 EUR/MWh

  11. Conclusion, emission In year 2010 in Elva was avoided 4734 t of CO2 em. For chiping and transport of fuel emission is 8 kg CO2 /MWh

  12. Conclusion, future perspective • Different development scenarios to be sustainable: • more consumers • closer involvment in energy suply chain • connecting grids to one network • CHP • use other renewable resources • (solarenergy, ground –thermal energy etc )

  13. Keep moving! Thank you!
