7,500 Inhabitants Supplied with Renewable Energy from 10 MW Storage System for One Hour in Power Outage Test Scenario

Bordesholm, a town with 7,500 inhabitants in the north of Germany, was disconnected from the utility grid and supplied exclusively with renewable energy for one hour, before being reconnected to the transmission line. A 10 MW storage system and battery inverters by SMA Solar Technology enabled the supply.

Designed and installed for reliable power supply in the event of grid failure, a 10 MW storage system with a capacity of 15 MWh provided by project developer Renewable Energy Systems (RES) entered service in early 2019. SMA supplied a coordinated system solution for the project comprising Sunny Central Storage battery inverters and an SMA Hybrid Controller XL equipped with stand-alone mode, black start and synchronization functions. The “black start” function allows the entire electricity supply to be restarted after a power outage. If the trial had been unsuccessful, the residents of Bordesholm would have had their power restored within just a few minutes.

“This successful trial is an important milestone in the energy transition,” said Boris Wolff, Executive Vice President Business Unit Large-Scale and Storage Solutions at SMA. “It demonstrated that renewable energies can supply power without impacting system stability. In fact, our Sunny Central Storage battery inverters and SMA Hybrid Controller supply the island grid with even greater stability and power quality than the utility grid.”

“The trial was an impressive demonstration of how it is already possible and economically profitable to systematically expand renewables along with the required storage capacities without endangering supply reliability whatsoever,” said Frank Günther, managing director of the Bordesholm utilities company. “We have been pushing this nationwide pioneering project forward for many years. Now we have proven that a 100% renewable energy supply is both reliable and economically efficient. This makes our municipality a pioneer throughout Europe for energy reliability. We have been able to show that system stability can also be achieved with renewables only.”
