FAQ

You can think of a battery park as a scaled-up version of rechargeable home batteries, designed to store energy for later use. But instead of powering one device, it has the capacity to supply entire neighbourhoods or businesses, exactly when the need is greatest.

Battery parks are an important asset to offset the highly variable input and output of renewable energy sources like wind and solar farms. In our country, the sun is not a regular visitor and wind power also varies day to day. Battery parks allow us to respond swiftly to fluctuations in supply and demand, which greatly helps to keep our electricity networks flexible and stable as we phase out fossil and nuclear power plants. They make it increasingly easy to integrate renewable but variable energy sources into our energy grid. Another major plus when it comes to battery parks, is the reduction of energy waste by storing excess energy for later use. Energy security also improves when we can rely on battery parks during breakdowns, grid overloads or times of reduced power production.

The main challenges are high investment and installation costs, reduced storage capacity over the years and the environmental impact of battery production and disposal. Thankfully, the rise in use of energy storage systems also ensures further improvements. Construction costs are lowering and the number of recycling technologies for battery systems is increasing.

After about 20 years, battery units are written off, but remain perfectly usable for further applications. After reaching the 'end-of-life' phase, there is a take-back obligation so that the battery supplier can recycle them responsibly.

On average, it takes one to two years for the construction and completion of a single battery park.
