Energy Solutions Group Secures Financing for 75 MW Battery Storage Project in Harmignies energy storage

Energy Solutions Group (ESG) has successfully secured project financing for its innovative 75 MW / 300 MWh energy storage project in Harmignies, near Mons, Belgium.

The project, under construction and set to be operational by autumn 2025, aims to address the growing demand for flexible energy solutions and contribute to the sustainable energy transition. ESG has partnered with KBC Bank and Wallonie Entreprendre to secure the necessary financial backing.

The Harmignies battery storage system, which will consist of 82 Tesla Megapacks 2XL, will deliver 75 MW of power for 4 hours. It is located on an industrial site next to an ELIA high-voltage substation, a key site for integrating renewable energy into the Belgian grid. This project marks ESG's second and largest BESS (Battery Energy Storage System) in its portfolio, reinforcing its commitment to energy transition efforts in Belgium.

Frederik Jansen, ESG’s CTO, emphasized the collaborative efforts of partners Spie, Yuso, Sweco, House of Projects, and Tesla in delivering this pioneering project. The milestone of reaching financial close was celebrated as a significant step towards energizing the green transition in Belgium.

Olivier Bouchat of Wallonie Entreprendre highlighted the importance of battery storage parks in stabilizing Belgium's energy grid, especially with the increasing reliance on decarbonized energy sources. Wallonie Entreprendre's investment supports the region’s transition to a more sustainable and circular energy future.
