• 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

Environment and Energy Operative ProgrammeMain 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

Environment and Energy Operative ProgrammeOther 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

• A support programme appeared in April, 2008• Many applicants and winners• Very slow process• Gardeners started to drill geothermal wells on
their own finance.

Preliminaries
New direct heat geothermal systems in Hungary - Gábor Szita, president of Hungarian Geothermal Association
• Target: Heat supply for all public facilities based on geothermal reservoir explored by the drilling in 1982
• Preparation steps:– Procurement of necessary permits (water management and
environmental)– Elaboration of a feasibility study– Applying for state subsidy– Waiting for considering the application– Signing the subsidy contract– Preparing the tender documentation
• Project owner: Municipality of Bóly

Project Preparation
New direct heat geothermal systems in Hungary - Gábor Szita, president of Hungarian Geothermal Association
• 2 new thermal wells (1500-m borehole depth expected)– 1 production well– 1 injection well
• Geothermal technology: submersible pump, tanks, supply and injection pumps, filters, etc.
• Total length of the transmission and distribution pipe-line: 7 km• Geothermal substations at 15 different places: heat exchangers,
control valves, measure and control gauges, etc.• Civil works: 2 small pump houses, manholes• Electric works: electric supply, switches, breakers, etc.• Automatic control and monitoring system, communication: hardware
and softwareConstruction start-up: July 2007Operation start-up: November 2008In

• Organisation of 6 workshops.
• Publishing a quaternary newsletter for the members.
• Successful negotiation with the Ministry of Environment and Water in 2005-2006.
• Giving opinion on new measures and programmes related to geothermal.
• Explaination for the original meaning of the word „THERMAL”, used in European languages in geothermal.
