Three Buildings Planned

Three buildings are planned at the 25,000 sqm site named FRA1-Mainz, and situated in an already existing industrial area adjacent to KMW’s power plants. Local authorities have approved the building application, and construction will start in Q3 2023. This location has the ability to accommodate both multi-tenant agreements and dedicated facilities for larger client installations.

According to the statement by the company, the FRA1-Mainz site has all the necessary conditions in place to establish itself as one of the most environmentally-friendly data centers in the world.

  1. KMW’s renewable energy portfolio covers the power supply.
  2. It will be cooled by the adjacent Rhine River, making it very energy efficient with a PUE below 1.3.
  3. The KMW gas plant will supply the backup power, making diesel generators for emergency power redundant.
  4. Strong connectivity is secured with a location close to the Frankfurt DE-CIX hub.
  5. Up to 60 MW of waste heat will be fed into the Mainz district heating system, making sure the precious energy resources are used optimally. This district heating grid supplies up to 1000 properties in the city.
