profitable exploitation of geothermal waters ▪ Examples O&G fields with geothermal Geothermal Potentials for Energy Purpose potential: Molve, Kalinovac, Beničanci etc. 12 OVERVIEW OF ACQUIRING RIGHTS ON MARKET PREMIUM IN GEOTHERMAL ENERGY Preliminary Location Construction Construction of Operating Permit EXPLORATION ACTIVITIES Plan Permit Permit Facility /Plant Agreement on the Energy Reserves Electricity Consent Agreement on Acquiring the status Acquiring the Production Approval study Market of an eligible rights on Market of Geothermal Waters Premium electricity producer Premium Network Connection Agreement Permit for performing energy activity MESD -

CEMO HERA - CERA CERA - Croatian Energy Regulatory Agency (HERA) 13 2 types of Renewable Quotas for Public tender for incentives for Text Here power market geothermal premium award renewables energy Legal regulation The law envisages 2 possibilities, Regulation on quotas Conducted by Croatian Energy within defined quota: Market Operator (HROTE) by Law on Renewable Energy for stimulating the Sources and High-Efficiency 1) Incentive premium for production of electricity TENDER STEPS: Cogeneration and its by-laws projects greater than 500 kW from renewable energy 1) "Reference price of electricity" is defined for each of installed capacity sources and high-efficiency each type of renewables 2) Feed-in tariff system for cogeneration covers the 2) A public tender is held for the award of a the projects bellow 500kW period from 2020 to 2022 – premium within a defined quota (protecting small investors ie. quotas for geothermal 3) The most favorable bidder (with the lowest households) energy is 20 MW* production price) have to acquire the status of an eligible electricity producer and CROATIAN conclude a power purchase agreement with HROTE on the payment of a premium for 12 years ENERGY 4) Electricity producers enter a contract for the sale of electricity on the market with LEGISLATION authorized market participants (suppliers, stock exchange and others) 14 CONCLUSION There is a lot of undiscovered geothermal potential with estimation of more than 800 MW, thus since the end of 2018, Croatian Hydrocarbon Agency has launched activities related with issuing new exploration licenses The actual achieved results • First geothermal plant Velika 1 in Velika Ciglena – 10 MWe (brutto 16,5 MWe) • The one of kind geothermal power plant in Croatia and European Union In Law on Exploration and Production of Hydrocarbons (OG, No. 52/18, 52/19) and its by- laws all procedure of tender and issuing licence for exploration and exploitation geothermal waters for energy purpose is explained in detail Ministry of Economy and Sustainable Development and Croatian Hydrocabon Agency, as state institutions, together with the Government of the Republic of Croatia, support the investors in investing in projects related to geothermal energy, as well as solving all possible uncertainties 15 VELIKA CIGLENA Successful story Velika 1 -
