SPIE Belgium to integrate 304 MWh battery park in Auvelais
- Site capacity ~304 MWh able to inject up to 76 MVA into the 150 kV grid for 4 hours.
- Park will include 82 Megapack-type battery containers and an 82 MVA power transformer.
- System can supply 30,000–40,000 households for 4 hours or fully recharge 4,000–5,000 electric vehicles.
- Civil works to run until summer 2026, with contractual commissioning scheduled for end of January 2027; ~14,000 hours of work and up to twenty technicians at peak.
Purpose
The Auvelais battery park will store electricity, notably of renewable origin, produced during surplus periods and return it during consumption peaks to support grid flexibility and integration of intermittent generation.
Capacity and equipment
The site will have a capacity of approximately 304 MWh and can inject up to 76 MVA into the high-voltage grid (150 kV) for four hours. The installation comprises 82 Megapack-type battery containers associated with an 82 MVA power transformer, representing the ability to supply 30,000–40,000 households for four hours or to fully recharge 4,000–5,000 electric vehicles.
SPIE Belgium scope
SPIE Belgium is responsible for the electrotechnical integration: construction of the 150 kV substation, installation and connection of the storage systems, and implementation of all equipment necessary for injecting energy into the grid.
Schedule and workforce
Civil engineering works have begun and will continue until summer 2026, with installation and connection to follow and contractual commissioning scheduled for the end of January 2027. The site represents approximately 14,000 hours of work and will mobilise up to twenty technicians on site at peak activity.
