Our story

Edison Energy and Patronale Life, who independently began their journey towards solar energy in 2009, came together in 2015 to unify their vision under the name Patronale Solar.

Patronale Life, an institutional player, sought long-term investments with a positive social impact. Edison Energy, on the other hand, started as a dynamic start-up, founded by a group of young professionals who met at one of Belgium’s largest traditional energy providers. Driven by their entrepreneurial spirit, they aimed not only to instigate change but also to leave a lasting imprint on the world.

Since the inception of this unique partnership, the founders of Edison Energy have assumed the management of Patronale Solar, which has been known as Energy Solutions Group since 2023. The company’s mission is clear: to promote the transition to sustainable energy in the Benelux region and surrounding countries. With this vision, the company strives to play a leading role in the world of sustainable energy.

The transition from Patronale Solar to Energy Solutions Group in 2023 reflects our development and the expansion of our focus. With Patronale Solar we worked on a solid foundation and uninterrupted growth. Since then, we have expanded our portfolio further with wind power, energy storage and fast charging solutions. Our diverse energy portfolio and partnership with committed, experienced partners are some of the factors that set Energy Solutions Group apart from other sustainable energy companies.

Thanks to our expanding expertise and performance in the field of green energy, we have grown to become one of the largest independent green energy producers in the Benelux. We manage over 350 energy production sites, resulting in an impressive and diverse energy portfolio.

As we look to the future, we are determined to continue playing a leading role in the sustainable energy sector and to pursue our ambitious growth path. Our vision for the future includes expanding to new markets and harnessing emerging technologies in order to make an even bigger impact on the transition to sustainable energy.
