Schalast advised KMW on joint venture with Green Mountain for the construction of a new data centre

Frankfurt am Main, March 31, 2023

On March 30, 2023, the energy producer Kraftwerke Mainz Wiesbaden Aktiengesellschaft ("KMW") and the Norwegian data center company Green Mountain signed a joint venture agreement for the construction of a data center on the Ingelheimer Aue. KMW was advised on the establishment of the joint venture with Green Mountain in almost all legal aspects by Schalast's team led by Corporate Partner Kristof Schnitzler, in particular in the areas of corporate law, real estate law and energy law.

The two companies each have a 50 percent share in the new data centre company Green Mountain KMW Data Center GmbH.

The state capital of Mainz has already approved the building application. Three buildings with a total IT capacity of 54 MW are to be built successively on the Ingelheimer Aue on a site area of 25,000 square metres, which corresponds to about three and a half football pitches . Construction of the first building is expected to begin in autumn 2023.

Kristof Schnitzler, Corporate Partner at Schalast, explains: "The establishment of this joint venture is of particular importance for our client, Kraftwerke Mainz Wiesbaden, as it is at the same time the conclusion of a lengthy process and the starting shot of an extremely exciting project. It is precisely the combination of secure, emission-free power supply, sustainable heat utilization and efficient cooling that makes the data center unique, even considering its size. We were very pleased that Schalast was able to accompany Kraftwerke Mainz Wiesbaden in this project with a team from different practice groups."


Sustainable partnership

KMW is using synergies at the site to sustainably supply the buildings and is responsible for their subsequent maintenance. The company will provide specialist personnel for this purpose

"It was important for us to find a partner with sufficient experience in the construction and operation of data centres as well as in the area of customer acquisition. Green Mountain complements us perfectly," explains Dr Oliver Malerius, CEO of KMW.

Green Mountain operates highly secure and sustainable data centres in Norway and England. The Norwegian company will market the data centre space and bring customers to the Ingelheimer Aue.

"Green Mountain has a vision to set the green standard in the data centre industry. That's why we particularly liked KMW's environmentally friendly approach to data centre operations," reasons Svein Atle Hagaseth, CEO of Green Mountain.
