Yourlogo • Energyuse in Slovenia The importance of wood biomass in Slovenia: Annual use of renewable energy sources in Slovenia Annual use of energy in households (Source: stat.si) Enduseofenergy in households 2012
Whybiomass? Keeps stores of fossil sources CO2 neutral Support stability of rural areas Improves incomes from agriculture and forestry Based on localsupply Providingjobopportunities in localenvironment
Yourlogo • Biomass supply- forests in Slovenia -
Localbiomasssources Non forest biomass The worst quality wood from forests Felling residues Wooden residues (recycling) Etc. Quantity:

Biomasslogistics • Wood drying: • Biomass trade center, storing of biomass • Biomasslogistics
Mikro mreža Heatingnetworks Individualheatingsystem Microsystemheatingnetwork Districtheatingnetwork
Biomass heating contracting for public building Heating system= heating boiler (wood chips, supplied by automatic system + boiler room) Investor is authorized for operation, service, maintenance and possible new investments The contract lasts at least 15 years
Heatingcontract Based on usual heating contracts for district heating systems Use of heating energy is measured regarding heating value of wood (measured by heating supplier) Use of heat is accounting based on actual energy consumption The system is insured together with the insurance for building
Administrative barriers Decision making process with municipality Permissions of land owners/ public (impact on environment) Subscription fee? Investment reimbursement (subvention)? Building permissions
Technicalquestions • Sanitary warm water in summer season • Basic requests regarding: • Heating room • Boiler • Installations • Biomass supply (driveways)
Investment plan Investment costs: 600-700 €/kW installed power Heatingboiler, supplyingsystem: 200-300 €/kW installed power Hotwatersystem: 80-100 €/m’ route Variablecosts: Biomass (17- 21 €/sm3) Power Maintenance
Investment plan Incomes: Subscription fee 160-250 €/kW installed power Energy price (70- 90€/MWh)- 2500 working hours/a
Publicawarenessrising Identification and promotion of project Working with different target groups: public, Excursions, best practices exchange
Typicalproblems: Too late: other plan, heating system on gas, heating room is constructed Not enough demand on heating Projectengineers are not flexible enough ADVISE: NEVER GIVE UP!!!
Questions? THANK YOU FOR YOUR ATTENTION!
