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
Karlovac County in Action!Strategy for Karlovac County Sustainable Energy Utilization
Karlovac County in Action!
Solar thermal collectors for households 2009 Subsidies for 60 households 48 Solar thermal
systems installed
Karlovac County in Action!
• Renewable energy utilization systems 201045 solar thermal collectors5 geothermal heat pumps5 photovoltaic5 small wind generators
• 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)

• Covers an area of approximately 179 km2
• Population – 7 932 people• Transit and traffic position -borders
with Republic of Slovenia
City of Ozalj – District Heating
• Analysis of several variants of possible solutions with different number of heat consumers and boiler locations:City centreCity centre with industrial zone – boiler in
industrial zone
