This facility will boast a remarkable storage capacity of 2,800 MWh of electricity.

The agreement concluded with our contractors, including Sweco, to be GIGA Storage Belgium’s partner for the design of the Green Turtle battery park comprises an important milestone. This is a flagship project for us in Belgium and an important project in realising the energy transition in Europe, where access to large-scale electricity storage plays a vital role. Sweco has been selected as our partner for the integral design because of their solid expertise in battery energy storage systems (BESS).

The park will play a crucial role in the energy grid by supplying stored renewable energy during times when solar and wind production is low, thereby decreasing Belgium’s dependence on gas power plants. Sweco will be responsible for designing the civil and electrical engineering aspects of the battery energy storage system (BESS). Construction is scheduled to commence in the summer of 2025, with the new battery park expected to be completed by 2028.

The planned Green Turtle battery park will have a capacity of 700 megawatts, which translates to a storage capacity of 2,800 megawatt-hours, enough to meet the average annual energy needs of 385,000 households.

By taking on the responsibility for the integral design of the Green Turtle battery park, Sweco will support GIGA Storage in laying the foundation for a resilient and sustainable energy system. In Belgium and across Europe, Sweco’s experts are heavily involved in the expansion of renewable energy and in the adaptation of power systems and electricity grids, to support clients in meeting new capacity requirements as electrification intensifies.

Located in Dilsen-Stokkem, the battery park will capture excess wind or solar energy as it is generated, making renewable energy available on the grid during peak demand periods. This approach enhances the efficiency of renewable energy usage and helps to prevent wind turbines and large solar panel installations from being turned off to ease grid pressure.
