Szczecin geothermal project launches. One step closer to drilling another well

• Multiconsult Polska from Warsaw will act as geological supervisor and supervisor for work related to a geothermal drilling project at Dąbska Street in Szczecin.
• It will also influence the specifications necessary to select the contractor for the geothermal well itself, and the procedure aimed at selecting the drilling contractor will be the next stage of the investment.
• For the work to enter the main phase, it is necessary to select a contractor for the geothermal well.

The Waste Disposal Plant acts as a substitute investor for the city of Szczecin in the implementation of the project entitled "Drilling the exploration and appraisal well for thermal waters Szczecin GT-2 in the city of Szczecin".

For the first test well, Szczecin received funding from the National Fund for Environmental Protection and Water Management under the "Sharing Thermal Waters in Poland" program. The agreement signed with the National Fund for Environmental Protection and Water Management in December 2024 amounts to PLN 12.9 million to cover investment costs related to the well.

Two companies from Warsaw submitted their applications for the tender for the task entitled "Performing the function of geological supervision and supervision during the implementation of the investment entitled: Drilling the exploration and appraisal well for thermal waters Szczecin GT-2 in Szczecin." Multiconsult Polska and Geotermia Polska sp. z o. o. submitted their applications. The offer submitted by Multiconsult Polska was selected as the most advantageous and the contract was concluded with this company.

For work to enter its main phase, a contractor for the geothermal well must be selected. Preparation of the documentation for this selection will be conducted in close collaboration with the entity responsible for geological supervision and oversight. We will announce the announcement of this process in a separate announcement.

- says Anna Folkman, spokeswoman for ZUO.

Once the contract is signed, the drilling contractor will have 10 months to complete the project. Another 6 months will be devoted to developing hydrogeological documentation.

The planned well is located on plot no. 6/2, district 4084, at Dąbska Street in Szczecin. The total area of ​​the investment plot is approximately 1.42 ha, and work will be carried out within the designated drilling area, which covers an area of ​​approximately 1 ha. Currently, this area is partly used as a coal yard for the Dąbska Heating Plant, and the remainder is undeveloped. The immediate surroundings of the plot on which the planned investment is planned include: wooded and shrub land to the north and northeast, class VI agricultural land to the west and south, and industrial development areas to the east.

According to Anna Folkman, Szczecin is located in an area with good geothermal conditions, the temperature of underground water (at smaller depths characterized by significant salinity) is 60-80 degrees Celsius.

According to available data, the heat flux in the Szczecin area is approximately 90-100 mW/m², which is one of the highest values ​​of this parameter in Poland. However, only a test well will allow for the assessment of the actual water parameters, as well as the final costs of the entire investment and its profitability.

- we read in the press release.

The project involves drilling the Szczecin GT-2 vertical well to a depth of approximately 1,950 meters, reaching approximately 30 meters of Upper Triassic formations. Based on the analyzed materials and hydrogeological survey results, it is assumed that the Szczecin GT-2 well will produce thermal water with a flow rate of 200 m³/h, a temperature of approximately 70-75 degrees Celsius, and a total mineralization of 120-130 g/l.

"Utilizing geothermal resources is one way to reduce CO2 emissions and other pollutants in the atmosphere by eliminating environmentally damaging fumes from burning conventional fuels. Investing in geothermal energy is one of the elements of decarbonizing Szczecin's heating system and increasing the energy self-sufficiency of the Szczecin Municipality," the press release continued.
