- 250 million kilowatt hours of climate-friendly heat for around 20,000 homes

- Eavor director Daniel Mölk: “A decisive step for the heating transition in Hanover.”“
Hanover. A new milestone for Hanover’s heating transition: Enercity and Eavor signed the heat supply contract for the geothermal project in Hanover today. As of 2026, up to 30 MW of renewable and baseload geothermal energy will be available annually for Hanover’s district heating network. Geothermal energy will thus play a central role in the climate-friendly heating supply of Hanover in the future. Geothermal energy can be used to generate heat regardless of weather conditions. The two companies use Eavor-Loop™ technology, which produces heat by circulating a fluid in a closed loop through many kilometers of drilled pipelines at a depth of around 3,000 meters.
Geothermal energy for 15 to 20 percent of Hanover’s district heating needs
Once the project is completed, 15 to 20 percent of Hanover’s annual district heating needs can be met in a climate-neutral manner using baseload geothermal energy. The energy from the Earth is used to reliably generate up to 250 million kilowatt hours of district heating, which covers annual heating needs of up to 20,000 homes of customers in the Enercity supply area.
Enercity uses a new process to supply a large city
“The heat from the depths will make an essential contribution to ensuring that one-third of Hanover’s residents can heat their homes with climate-neutral district heating by 2027,” says Dr. Susanna Zapreva, chair of the Enercity Board of Management. “The facility with the innovative geothermal energy extraction will be the first metropolitan application of its kind and will enable us to decommission the last coal-fired unit in
our generation portfolio.” The geothermal energy will start being fed into the Hanover district heating network when the first loop goes online in 2026.
Renewable and independent energy for Hanover
“We are looking forward to this project and to using our technology to help convert a significant portion of the baseload of the district heating supply in the city of Hanover to renewable and independent energy,” says Daniel Mölk, Managing Director of Eavor GmbH. Eavor already operates a facility of this kind in Geretsried, Bavaria. The long-term heat supply contract between the two companies is an important prerequisite for further steps in the project. This includes, for example, the awarding of mining permits for the project. Eavor’s actual drilling is scheduled to begin in 2025 As soon as the first well provides heat, Enercity will start construction of a new district heating pipeline to the site.
