First of its kind: combination of wind energy and storage 01-06-2017

Grid stability

Giessenwind is one of the highest wind farms in the Netherlands. The three turbines have a height of 108 meters and jointly provide about 5,000 households with energy. The intermittent character of renewable energy sources such as wind increasingly requires new measures to stabilize the grid.

C-Wind is a consortium of Scholt Energy Services and wind farm Giessenwind. Wim Meerkerk, owner of Giessenwind: "Battery storage systems are necessary to integrate our ambitions with renewable energy in the Dutch electricity grid."

 

End-to-end solution

Alfen, a provider of a large range of products and services for the electricity grid, has delivered an end-to-end solution for this project, including the energy storage system of approximately 1 MWh, a transformer substation and the grid connection. Andreas Plenk, responsible for global sales of energy storage systems at Alfen: "Building on Alfen’s eighty-year experience at the high voltage we can deliver a turnkey end-to-end solution for our customers. Currently we are working on various projects that connect our energy storage system, called TheBattery, directly to renewable energy sources. TheBattery balances energy supply and demand and as such prevents significant grid infrastructure investments. The pressure on the grid is reduced, and at the same time, the generated energy can be sold at the most profitable moments."

 

 

Energy trading

Scholt is an energy supplier to businesses in Belgium, the Netherlands and Germany, and will initially use the storage system for energy trading. Sander Drissen, Business Development Manager at Scholt Energy Services: "This installation provides a sustainable basis for the future and can easily be expanded when necessary. We are also looking at other locations and applications such as local grid stability. "

The system was commissioned in May 2017 and currently generates the first results for C-Wind. Plenk: "With systems like this we are preparing the Netherlands for the electricity grid of the future: sustainable and reliable."
