Germany - Construction of geothermal power plants

Description

Stadtwerke Neuruppin GmbH has a district heating network that is currently supplied exclusively by boilers and CHP units. For decarbonization purposes, a geothermal energy center is to be built at the Heinrich-Rau-Straße site. The permit field to be used for this purpose has an area of approx. 13,448,600 m² and is located in the Ostprignitz-Ruppin district. Due to numerous boreholes in the immediate vicinity of the planned borehole location, which represent an exceptionally good data situation, the Aalen sandstone aquifer at a vertical depth of approx. 1,700 m was selected as the preferred target within the framework of the geological knowledge analysis. Based on the productivity index of PI = 135 m³/h / MPa, a production of 200 m³/h geothermal brine with a production temperature of approx. 70.5 °C can be realized.Based on the consumption characteristics of the entire heating network of the Neuruppin city center, an energetic balancing was carried out. As a result, approx. 76,000 MWh of geothermal heat can be fed into the district heating network with the use of high-temperature heat pumps.
In lot 11, all services and materials for the creation and treatment of drilling fluid in the two deep geothermal wells Gt Neuruppin 3 and 4 are requested. The services include the personnel, equipment and materials, as well as the mud programs. Drilling fluids for all sections in both wells are to be offered.
