Largest Dutch onshore wind farm to provide a quarter million Vattenfall customers with renewable energy

Vattenfall Dutch Wind Farm

Swedish state-owned power company, Vattenfall has signed a long-term purchasing agreement for renewable electricity from the new upgraded Zeewolde wind farm in the Netherlands.

The repowering work to exchange the existing wind turbines by more powerful turbines will be initiated on the farm by the year and is expected to last until the end of 2021. 220 existing wind turbines will be replaced by 91 larger and more powerful turbines which will produce more than 850 GWh every year. Making the Zeewolde, the largest onshore wind project in the country.

According to the agreement, Vattenfall will purchase power from 83 of the new turbines with an installed capacity of more than 300 MW.

“This is the largest purchasing contract that Vattenfall has ever concluded for renewable energy in the Netherlands. Zeewolde wind farm will supply sustainable electricity to 250,000 Vattenfall customers,” says Erik Suichies, head of Vattenfall’s European wholesale customer business.

The wind farm is owned by more than 200 farmers, residents, and entrepreneurs from the outskirts of Zeewolde. Together they form the largest farmers/ civil wind collective in Europe. “In Vattenfall, we have a solid partner in the first place, one with extensive experience in this area. I also find it positive to see that a local organisation such as ours and an internationally operating company like Vattenfall, know how to find each other,” said Managing Director Sjoerd Sieburgh Sjoerdsma at Windpark Zeewolde.

With the Windpark Zeewolde agreement, Vattenfall has now concluded purchase contracts in its various markets with a combined capacity of 6.5 GW.

Recently, we reported that Vattenfall, together with the Swedish company SaltX Technology, was testing how renewable wind and solar power can be stored in salt. The pilot plant at the Reuter thermal power plant in Spandau, Berlin, has a total storage capacity of 10 MWh and was recently commissioned. The patented technology developed by Swedish SaltX Technology is based on nano-coated salt. The technology enables this “salt battery” to be charged several thousand times and that the energy can be stored for weeks or months without losses.
