Győr

The system of Győr, commenced today, with full capacity is able to decrease the emission and so the quantity of the greenhouse gases – primarily carbon-dioxide, nitrogen-oxides – by approximately 67 000 tonnes on a yearly basis.

Geothermal Project of Győr in numbers:

The project – comprising three production wells and two reinjection wells, the Bőny Heat Centre and a 17-kilometre geothermal heat transmission pipeline, with a total cost of over HUF 10 billion – was implemented with the assistance of two 2 billion non-repayable EU grants, in addition to the investor’s own funds and a project loan.

The system of Győr, commenced today, with full capacity is able to decrease the emission and so the quantity of the greenhouse gases – primarily carbon-dioxide, nitrogen-oxides – by approximately 67 000 tonnes on a yearly basis. Furthermore, geothermal energy decreases the use of natural gas, with full capacity, by 35 million m3 on an annual basis, therefore contributing to the achievement of the goals set by the National Energy Strategy.

We have been harnessing geothermal energy for the benefit of household and industrial consumers for the last 10 years. Dénes Gyimóthy

Q4 2015.

The geothermal system begins operations.

October 2018.

October 2018 The Győr Geothermal System is transformed into a three production wells system – making it unique in Hungary –, as the BON-PE-03 well is successfully expanded as part of the concession project.

Parameters of the wells

  • BON-PE-01 productive aquifer: 2 450-2 470 m, fluid temperature 99,8 Celsius degree, yield: 285 m3/h
  • BON-PE-02 productive aquifer: 2 430-2 450 m, fluid temperature 98,8 Celsius degree, yield: 210 m3/h
  • BON-PE-03 productive aquifer: 2 500-2 580 m, fluid temperature 101,4 Celsius degree, yield: 800 m3/h
  • PER-PE-01 reinjection well depth: 2 296 m, capacity: 609 m3/h
  • PER-PE-02 reinjection well depth: 2324 m, capacity: 541 m3/h

Through a long term heat supply contract concluded between the PannErgy Group and Győr-Szol Zrt., geothermal energy provides approximately 40 percent of the total heat requirement of nearly 24 thousand homes and more than a thousand other customers in the Győr district heating system. In addition, the energy output of the Bőny heat centre provides at least 80 percent of the heating energy used by Audi Hungaria Zrt’s factory complex in Győr.
