As the battery energy storage systems can be charged with power from renewable sources, such as solar and wind, they play an essential role in supporting the shift to clean energy. They additionally help to stabilize the frequency in the grid in the short term when more solar and wind energy are being produced.
“BESS can store energy generated by wind turbines or solar panels, which means we can store clean energy and use it when electricity is expensive or when demand is high,” says Steffen Hagmann, Project Leader at Eltel. “The systems can also help to partially backup the national grid by meeting some of the electricity demand in the event of the power going down.
Eltel’s BESS solutions are modular and scalable, which provides flexibility for future needs. Hagmann likens the solution to Lego blocks.
“If a customer needs more capacity, we can simply add more battery containers, just like building with Lego,” explains Hagmann. “It’s a flexible system that can grow as demand increases.”
There is great potential to deliver similar projects to a variety of customers – not only in Denmark, but throughout the Nordics.
“One of our biggest clients, Copenhagen Airport, is looking to replace its old diesel generators with BESS systems,” says Hagmann. “If airports, which have significant environmental impacts, can reduce their greenhouse gas emissions through solutions like this, it will open up more opportunities for more sustainable operations.”
