RES and VBB Celebrate Construction Progress of 10 MW Storage Project

Three months after start of construction, the topping-out ceremony for the 10 MW battery storage facility in Bordesholm, Germany, was celebrated on September 12th. The collaboration of Renewable Energy Systems and the utility VBB has reached an important project milestone. The battery storage system will provide grid stabilization and back-up power from 100 percent renewable energy when there is grid disruption or upstream grid failure.

During the traditional topping-out ceremony Frank Günther, Managing Director of VBB said, "My thanks to all those who have worked on this construction. With this battery project, we will give an insight into the future of a digital and innovative energy world, which ensures an efficient and stable power supply with renewable energy alone."

Thanks to innovative and intelligent controls developed in-house at RES, battery storage is much more efficient than traditional system services using conventional coal or nuclear energy. The battery can respond within milliseconds to ensure the balance between production and consumption.

"For the widespread use of renewable energy, the energy market and energy-intensive companies need a reliable technology that guarantees the security of supply and provides flexibility at the same time. Therefore, energy storage units will play a major role in our electricity network," emphasized Matthias Leuthold, Head of Energy Storage for RES in Germany.

To date, the foundations, the solid construction, the carpentry and roof of the 450 m² building have been erected. The electrical installation for the lithium-ion storage facility, with a capacity of 15 MWh will now follow. For this purpose, a total of more than one kilometre of 20kV medium-voltage cable, as well as over three kilometres of 1kV cable will be laid. Another highlight of the construction phase is the installation of the 180 battery racks with a weight of 750 kg each - this is the heart of the entire battery storage system and the commissioning is planned for the beginning of next year.

The Bordesholm project is funded by the EU and the state of Schleswig-Holstein, which is promoting the development of storage technologies.
