Engie has started construction on a large-scale battery storage facility in Kallo, Belgium, as part of its strategy to enhance grid flexibility and support renewable energy integration. The site will feature 110 battery modules with a total storage capacity of 400 megawatt-hours (MWh), capable of delivering 100 megawatts (MW) of power for up to four hours.
The project is being delivered by NHOA Energy under a supply contract and long-term service agreement. The battery park is expected to be operational by spring 2027.
At full capacity, the system will be able to supply electricity to more than 48,000 households, helping to balance fluctuations in energy supply and demand, especially from intermittent renewable sources such as wind and solar.
“It is with great pride that we are launching today, in the presence of Energy Minister Mathieu Bihet, the construction of this battery park in Kallo, Engie’s second major park in Belgium,” said Vincent Verbeke, chief executive of Engie Belgium. “With this large-scale project, we are strengthening Belgium’s strategic position at the heart of the European energy market.”
Battery storage is becoming a central component of Engie’s Belgian energy strategy, complementing its renewable energy generation portfolio. The company emphasised the importance of flexibility in energy production and consumption to optimise the use of green power.
“Through our focus on flexible energy production and consumption, we want to get the most out of renewable sources and make energy more sustainable, reliable and affordable for our customers,” Verbeke added.
The Kallo facility will be Engie’s second major battery park in Belgium, as the country continues to invest in technologies that enhance grid resilience and energy transition goals.
