International Geothermal Workshop, RENEXPO, May 6 2011 Driving Forces behind the Acceleration • Reasons related to the natural gas – High dependency – High price – Ukrainian-Russian gas dispute • Availability of financial support • Geothermal projects may fulfil the requirements for the support The basic formula High gas price Geothermal Projects Support New direct heat geothermal systems in Hungary - Gábor Szita, president of Hungarian Geothermal Association
International Geothermal Workshop, RENEXPO, May 6 2011 Support Programme Environment and Energy Operative Programme Main conditions: – Support only for the investment costs – The share of the support depends on • • • the region the applicant (local authorities are preferred) the size of the project the (extra) revenues provided by the project the profitability of the project 10% < SUPPORT < 85% New direct heat geothermal systems in Hungary - Gábor Szita, president of Hungarian Geothermal Association
International Geothermal Workshop, RENEXPO, May 6 2011 Support Programme Environment and Energy Operative Programme Other important conditions: – Not available for agricultural entities – Strict scoring system – easy to loose, hard to collect points – IRR must be > 0 (for 15 years) – High quality feasibility study is required New direct heat geothermal systems in Hungary - Gábor Szita, president of Hungarian Geothermal Association
International Geothermal Workshop, RENEXPO, May 6 2011 Geothermal Boom in the Horticulture • • A support programme appeared in April, 2008 Many applicants and winners Very slow process Gardeners started to drill geothermal wells on their own finance.
