Advising Green Mountain on agreement with KMW for establishing a new 54 MW data centre in Mainz

We have advised Norwegian data centre Green Mountain, owned by Azrieli Group Ltd., on an agreement with energy company KMW to establish a new 54 MW data centre site in Mainz. Both companies have a 50% stake in the new joint venture. The data centre will be supported by renewables from KMW’s portfolio and operated to high sustainability standards.

Three data centre buildings are planned for the new 25,000 sqm site situated in an already existing industrial area adjacent to KMW’s power plants. The Mainz authorities have approved the building application and construction will start in Q3 2023. The site can support both multi-tenant contracts as well as dedicated buildings for larger client installations.

Green Mountain designs, builds and operates highly secure, innovative and sustainable data centres in Norway and the UK. The data centres are powered by low-cost, 100% renewable power, and the use of free cooling in the Norwegian data centers ensures high energy efficiency.

The company currently operates the following data centre locations: SVG1-Rennesøy near Stavanger, RJU1-Rjukan in Telemark and OSL1-Enebakk about 20 km outside of Oslo. In addition, a data centre was recently established in London (LON1-East) through the acquisition of an existing company and it is located in one of the most important data centre hubs in the world.

Green Mountain's existing customers include large international companies within cloud, banking/finance, HPC, automotive sectors and more. Data centre security is of the highest level and the company holds multiple ISO certifications.

The team was led by Daniel Ajzensztejn (Lead Partner, Commercial Real Estate, Hamburg) with support from Nathan Krapivensky (Senior Counsel and Co-Head of the Israel Group).
