SemperPower starts construction of a 68MWH EOS

SemperPower is proud to announce that it is entering the realization phase of its third large-scale energy storage project; Project Pollux. This battery system, with a capacity of 30 megawatts and a capacity of 68 megawatt hours, when commissioned in the fall of 2023, will be the largest operating battery project in the Netherlands, and thus also one of the largest in Northwest Europe.

Together with our project partners, we are entering the realization phase followed by the operation phase later this year. Essent will use the 30 MW/68 MWh battery system on a long-term basis to overcome the volatility of its renewable energy portfolio. This will again contribute to faster integration of renewable energy in the Dutch electricity market. As a supply and installation partner, Alfen will build the system on the North Sea Port site in the middle of the energy hub in Vlissingen-Oost, right next to twin sister Castor. The system will be connected directly to the Stedin network. The project is made possible with Triodos Bank, a.s.r. and sustainable investment fund manager Meewind as financing partners.

Dennis Schiricke (CEO, SemperPower): "We are proud to announce our third large-scale battery project in the near future. It once again underlines SemperPower's development capabilities and the leading role within the energy transition that the company is taking on with its project partners. Together we continue to accelerate the energy transition! In addition, the timing following the successful 'Power-The-Future' event and the accompanying launch of our new website and corporate identity is optimal."
