GIGA Storage Belgium. This facility will have a storage capacity of 2,800MWh of electricity. The park will make a significant contribution to the energy grid by providing stored renewable energy during periods of low solar and wind energy production — thereby reducing Belgium’s reliance on gas power plants.
Sweco will deliver the design of the civil engineering and electrical engineering works of the battery energy storage system (BESS). Construction is set to begin in the summer of 2025 with completion of the new battery park expected by 2028. The planned Green Turtle battery park will have a capacity of 700MW, resulting in a storage capacity of 2,800MWh, which is equivalent to the average annual energy consumption of 385,000 households.
Joeri Siborgs, general manager of GIGA Storage Belgium, said: “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 its solid expertise in battery energy storage systems (BESS).”
The battery park to be built in Dilsen-Stokkem will store surplus wind or solar energy as it is produced to make that renewable energy available on the grid during peak times. In this way, the battery park makes more efficient use of renewable energy and prevents wind turbines and large-scale solar panel parks from being switched off to relieve the grid.
Erwin Malcorps, business area president of Sweco in Belgium, said: “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.”
