Storage systems with SMA battery inverters enable stable power supply using renewable energies

“The disconnection, the island grid operation, and the re-synchronization with the utility grid went without a hitch,” said SMA system development engineer Paul Robert Stankat, who was on site at the trial. “The storage system supplied the town’s entire electricity demand which could thus be supplied exclusively from renewable energies.”

In addition to a grid formation function, the SMA battery inverters are also equipped with an optional “black start” function, which 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.

Bordesholm is a pioneer in energy security – also from exclusively renewable sources
“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.”

Background
In Bordesholm in Schleswig-Holstein, Germany a 10-megawatt storage system with a capacity of 15 megawatt hours and provided by project developer Renewable Energy Systems (RES) entered service in early 2019. Its main job is to deliver a primary operating reserve, supplies electricity for direct marketing and it is also designed to safeguard the power supply in the event of a grid failure. 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.
