Digital Realty is procuring hydroelectric power in Germany.

The colo firm this week announced it has signed a renewable energy agreement with the energy service provider Süwag Energie AG.

Under the agreement, Digital has secured Guarantees of Origin (GoOs) for 6,000MWh of hydropower – originating from the river Main – to start and run throughout 2024.

Digital Realty is purchasing GoOs from hydropower plants located close to its data centers in Frankfurt; Süwag's facilities in Griesheim and Eddersheim are reportedly located near the colo firm’s Digital Park Hattersheim.

"We’re delighted to announce the inclusion of 6,000MWh of hydropower in our renewable energy portfolio. The new project with Süwag not only reinforces our commitment to sustainability but also underscores how having a robust local partner in place is instrumental in achieving our local sustainability goals,” said Volker Ludwig, managing director, Digital Realty in Germany.

Ludwig continued: “This strategic deal represents a significant step forward in our global renewable energy strategy and exemplifies our commitment to reducing our impact on the environment.”

Mario Beck, managing director sales at Süwag Energie, added: "The Süwag Group is investing in increasing the efficiency and performance of its hydropower plants and is planning to further expand renewable energy plants, such as wind power and photovoltaics, in the region."

Digital operates more than 20 data centers across Frankfurt, totaling more than 826,000 sq ft (76,740 sqm) and 110MW of capacity.

Earlier this year Digital Realty signed a 10-year PPA in Germany with Engie for a 116MW share of a new 154MW solar project being developed in Brandenburg.
