Largest geothermal project in Hungary
Pannergy Plc. with Miskolc Municipality implemented the largest Hungarian geothermal district
heating project. The technical goal of the investment was to feed geothermal energy to the heating
system of Miskolc’s Avas district situated the nearest to the facilities in order to supply heat to the
prefabricated buildings of the local housing estates. Two producing wells provide the thermal water.
The heat output of the thermal wells are transmitted to the heat consumers via pipelines and heat
exchangers, while after cooling down the fluid is reinjected by three reinjection wells. The
technology ensures the operations of the largest geothermal heating plant of Central Europe.
Utilisation of three different renewable energy sources
In Miskolc 51.19% of the consumers (~32,000 houses and ~1,000 other
consumers) have been supplied with renewable energy for heating in 2014 –
2015 heating season, resulting in triggering 20,810,681 m3 natural gas and the
reduction of CO2 emission by 39,496 tons.
