  6. Location Ludza “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga

  7. Co-operation partners Lindeks ESSENT supported by Dutch Government Municipality of Ludza Investor Investor Investor Supply of wood biomasss Ludzas Bio-Energija Heat production 14 MW Biofuel Heat end users Heat energy distribution Heat energy > 29000 MWh/year Light oil “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga

  8. Erection of new boiler house • Supplier of boiler house equipment was Dutch company KARA Energy Systems. • Building works wereperformed by local company Valmieras SCO centrs. • Installation was finished in December 2000.

  9. Technical solution Chimney Chimney Diesel oil Flue gas filter Diesel boiler Wood chips Fuel tank 7 MW Wood chips storage with walking floor Open storage for wood chips 7000 m3 Wood boiler Transport system 8 MW Network pumps Heat meters Heat exchangers 2x8 MW District heating grid Property of Ludza municipality Property of LBE

  10. Logisticsof Biomass LBE boiler house (Ludza) Lindeks - wood processing (Ludza, 8 km) Verems - plywood production (Rezekne district, 27 km) Junions - wood processing(Ludza, 2 km) Ludzas MRS - wood processing and forestry (Ludza district, 20-40 km) Graudi - cleaning of roadsides/under power lines (Ludza district, up to 40 km) Lapegles 2 - forestry (Ludza district, 15 km) Nomis - wood processing and forestry (Rezekne district, 45 km) Vels 2 - wood processing and forestry(Daugavpils and Kraslava district, up to 120 km) The most of suppliers are situated in 45 km radius “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga 10

  11. Securing of biomass • Initially agreement on wood fuel supply was concluded between LBE and biggest local wood processing company LINDEKS • The contract term is 15 years • Payments for the biomass were made according to produced MWh of heat • Fuel moisture 40-60% on wet base • On 2005 Lindeks reduced amount of output

  12. Securing of biomass • For reduction of the risk related to only one supplier, we have agreed that part of biomass is supplied by alternative suppliers – the biggest plywood producer “Latvijas Finieris” and other local companies. • Payment for delivered biomassnow is made per loose cubic meter. • Fuel moisture 20-55% on wet base.

  13. Looking a hed Wood chips from forestry Actualcost ~ 5,5 LVL /m3loose “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga

  14. Securing of biomass Wood chips from wood-processing (ashes under 1,5 %) Wood chips from bushes (ashes under 3 %) Wood chips from forestry (ashes under 20 %) “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga

  15. Operational results Fuel balance Fact 2008 Estimated Diesel oil, 30 Ls/MWh (43 EUR/MWh) 75% 98% Wood fuel, 9,50 Ls/MWh (13,57 EUR/MWh) 25% 2% “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga

  29. Assembling of condenser “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga 29

  30. Benefits • Consumes for 10-20% less fuel • More power from boiler • Fossil fuel consumption reduces by 150 tons / year • GHG emission reductions of 500 tons / year • Reduction of hard particleemissions • Strengthening of the competitiveness • Option of installing similar condensers in other boiler houses “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga 30

  31. Conclusions • Heat production from biomass could be feasible and cost-effective • In Latvia amount of sustainable wood biomass is enough • Cheap fuel dos’t meen cheaper energy “BioenergyPromotion 2 ” The Latvian Environmental Investment Fund, October3, 2012, Riga
