Its role EPC
Ardelec Energie is a French company specializing in high-voltage (HTA) and low-voltage (BT) electrical distribution solutions. Established in 1999 in Herlies, Hauts-de-France, it offers custom-designed equipment, installation, maintenance, rental, and sales of transformer stations, switchgear cells, transformers, and related infrastructure components.
The company operates throughout France, with regional agencies supporting projects in renewables, public distribution, and industrial sectors. It serves clients including utilities such as Enedis, renewable energy producers, construction firms, and various industries, providing services like grid connections and equipment revalorization.
In November 2025, Ardelec Energie was acquired by Entreprise Redonnaise d'Électricité (ERE), creating a combined group with annual revenues exceeding €60 million and nationwide coverage in the HTA-BT sector. The entity is jointly managed by Julien Pau of Ardelec and Ludovic Bianchi of ERE, with backing from investors including LBO France Gestion.
Ardelec Energie has been involved in major infrastructure projects, including advancing electrical installations at ProLogium's Dunkirk gigafactory site as of 2026. It positions itself as a reactive specialist with strong stock holdings and comprehensive service offerings in France's energy infrastructure market.
