Who is Mega Energie and what are its activities in France?

Mega Energie is an energy supplier (electricity and natural gas) created in 2013 by a group of Belgian entrepreneurs. The company obviously operates in Belgium, France (since 2018) but also in the Netherlands.

In France, the head office is located in Montpellier. The company employs more than 20 people and only collaborates with local partners. Mega Energie is fully committed to supporting the local economy, as it does in Belgium through its parent company.

Mega Energie offers green electricity, resulting from the Guarantees of Origin mechanism, but also natural gas offers to individuals and professionals.

The company has more than 700,000 customers delivered in France and Belgium.

Electricity supply offers dedicated to professionals

A unique offer is proposed in the Méga Energie catalog in terms of supplying electricity to businesses:
