History & Development

The Stargard geothermal is not slowing down. Our ambition is to fully exploit the potential that lies beneath our feet. We continue to develop infrastructure, aiming to further increase the share of green energy in the district heating system. For us, each new well is a step towards complete energy independence of the city and proof that Stargard sets European standards in the field of renewable energy sources.

With a thermal capacity of about 42 MW, Stargard geothermal energy is one of the industry leaders in Poland. With energy production at the level of more than 400 thousand. GJ annually, the installation meets around 60% of the city's heat needs. The applied modernization and implementation of a collector system unique on a national scale ensured optimal operating conditions of the entire system, making it one of the most innovative geothermal installations in Poland.

The high temperature and high brine output from the GT-6 and GT-7 wells meant that the existing GT-2 mine hole was converted into a pushing hole in 2022. Thanks to this treatment, a much greater efficiency of the entire heating system was achieved. Since then, the plant began to operate on the basis of a system of seven holes (2 extraction and 5 pushing), which guarantees maximum stability and high efficiency of operation of the deposit.

An important milestone in the development of the company was the commissioning in 2020 of two modern reinjection holes: Stargard GT-4 and Stargard GT-5. This investment, realized with significant support from European Union funds, significantly increased the stability of the system and the efficiency of returning chilled water to the reservoir. The inclusion of the Stargard GT-6 and GT-7 boreholes was also crucial, making Stargard Geothermal the only one in the country to operate in a unique collector system of seven wells (3 extraction and 4 pushing), which ensured maximum efficiency and safety of the deposit. This allowed the company to consolidate its position as a leader in ecological heating in the region and to increase the city's energy security.

Since 2017, with the commissioning of the GT-3 hole made a year earlier, Stargard geothermal has started to move away from traditional doublets in favor of a collector system unique in the country. This investment not only significantly increased the thermal capacity of the plant, but thanks to the possibility of freely directing the brine between the holes, it provided even greater control over the extraction and compaction process.

In February 2012, after a major overhaul, the system was restarted. Since then, the installation has continuously powered PEC Stargard, maintaining very high operational parameters.

In 2011, the company's assets were acquired by G-Term Energy Sp. z o.o. The new owner carried out a number of key investments and repair work on the existing Stargard GT-1 and Stargard GT-2 vents, restoring the plant to full operation.

The first extraction of hot thermal waters in Stargard began in 2005. The obtained heat went to the city network, providing residents with hot water and — in cooperation with Przedsiębiorstwo Energetyki Cieplnej (PEC) Stargard — energy for heating buildings.

The company was established in 1999 under the name Przedsiębiorstwo Usługi Ciepłowniczych GEOTERMIA Stargard Sp. z o.o. It was a joint venture between DIFCO ENERGI (Denmark), SCANDINAVIAN ENERGY GROUP (Denmark) and “EKO-INWEST” S.A. (Poland).
