Karlovac County

• Situated in the central part of Croatian state territory

• Covers an area of approximately 3.622 km2

• Population - 141 787 people, density 39/km2

• Important transit, traffic and geostrategic position

• 5 cities (Karlovac, Slunj, Ozalj, Duga Resa and Ogulin) and 17 municipalities

Karlovac County – Biomass Potential• Considerable forest biomass potential: 57% of total

area covered with forests (33,6% private forests and 66,4% state owned managed by national company – Hrvatske šume Ltd. )

• Annual allowable cut 550.000 m3

Karlovac County – Biomass Utilization• Biomass mostly used in households and wood

industry• Total capacity of industrial biomass boilers: 22 MW

(wood residues)• 73% of population uses fuelwood as energy source

for heating (2001) – mostly old and inefficient wood stoves

• Majority of public buildings uses oil as energy source for heating, only 1% uses fuelwood

Karlovac County - Goals

• Gradual replacement of oil boilers older than 15 years with biomass boilers in public buildings

• Plans for 2011Add 10 pellet boilers

to competition

Initiative of the City Mayors

• The mayors of the cities in Karlovac county recognized advantages of biomass heating

• Support from the North-West Croatia Regional Energy Agency - REGEA

• REGEA analyzed and recommended several solutions-Duga Resa, Ozalj, Slunj

• Preliminary projects of biomass district heating and fuel oil boilers reconstruction

Available Sources of Funding

• Environmental Protection and Energy Efficiency FundUp to 1.4 million kn (maximum of grants)!– Up to 80% area of special state concern– Up to 60% if they are located on islands or in

mountain areas– Up to 40% in other areas

Available Sources of Funding

• IPARD (5th component of Instrument for Pre-Accession Assistance)– Possible financing up to 7 million kn (100% of investment)– Only for cities and municipalities with a population of less

than 10,000 according to 2001 census – In charge - Ministry of Agriculture, Fisheries and Rural

Development– Requirements: project documentation (concept design, main

project, investment study) and permits (location, building) - acceptable costs!

– Construction or reconstruction of district heating systems for the use of organic waste from agriculture and forestry (biomass)
