WIND PARK HELLEGATSPLEIN TO BECOME A SUSTAINABLE RENEWABLE POWER PLANT

Energy supplier Greenchoice and Greener Power Solutions have opened a charging hub for mobile battery containers at the Hellegatsplein wind farm. The flex charging hub is equipped to accommodate ten mobile batteries, which are linked to the national electricity grid and are charged directly from the four existing windmills. Spectral has developed the software that ensures correct control of the batteries so services can be provided to help balance the national electricity grid. Thus making the wind farm a hybrid sustainable energy + battery storage plant. The ultimate goal: to make fossil fuel power plants obsolete!

Challenge
In 2019, Greenchoice already installed a stationary 10 megawatt-hour battery at the Hartel II wind farm to contribute to a stable and sustainable energy system in the Netherlands. This wind farm has a yearly production capacity of 68 GWh and generates sufficient energy for 27,500 households in the Netherlands. The Hellegatsplein wind farm represents an annual production capacity of 41.5 GWh of sustainable energy – the equivalent of 16,500 household’s annual energy consumption. The Hellegatsplein wind farm consists of four Alstom Power 110 wind turbines, with a total capacity of 12MW. The ten Greener Power Solutions mobile batteries each have an energy storage capacity of 336 KWh. The Greener mobile batteries must be installed and removed when necessary based on the requirements of the Hellegatsplein wind farm.

Approach

The charging zone at Hellegatsplein will accommodate ten Greener mobile batteries, which can store 336kWh each. The batteries will be charged directly from the wind turbines, and the integration with the Spectral Smart Energy Control System will control, automate and optimize various events, making operation more sustainable, and achieving flexibility on the Dutch national electricity grid. As the batteries are completely mobile, they can be relocated and (re)installed based on site requirements, ensuring a new level of flexibility.

Outcome

Spectral’s Smart Energy Control System, which when integrated with Greener batteries, will provide realtime insights into battery performance, automate distribution FCR capacity, and automate messaging to Tennet. Spectral then steers battery and wind farm production with energy market requirements, keeping levels within set points, supports imbalance trading, and automate grid connection import/export contractual compliance.

“There is increasing supply and demand for green energy from the sun and wind in the Netherlands. To keep this in balance at any time of the day, the need for flexibility in the electricity grid is growing. We want to meet this need with sustainable solutions so that the use of fossil fuels – with which the electricity grid is now mainly kept in balance – can be phased out. This hybrid sustainable power plant at Hellegatsplein is therefore a crucial step towards a fossil-free future.”
