Gelec Energy - Powered for life


To continue to move forward in the development of high performance generators, to develop systems that meet the energy needs of our time, to stretch the boundaries of hybridization, to coordinate and manage various energy sources, and to design Off-Grid micro-networks for extreme conditions, these are the challenges that GELEC faces each day.

GELEC Energy takes a different view of the solutions that are currently available for energy production by combining traditional techniques with new technologies, fossil energy with renewable energy.

GELEC Energy concentrates on the energy market: one of the largest and fastest growing markets in the world. GELEC wants to introduce efficient alternative energy solutions to a market that is traditionally supplied by Diesel electric generators.

GELEC designs, manufactures, constructs and assembles electricity production solutions, Diesel or biofuel thermal electric generators and hybrid micro power stations.

Its investment in Research & Development lets GELEC create new solutions for state of the art energy production: The electric generator that operates using oil also the development of PV-diesel electric power stations.

Our research department designs and monitors the manufacture of very powerful containerized units or responds to specific integration problems.

So far, GELEC Energy has equipped over than 2,000 sites with generators, HPOD or PV / Diesel power stations on all sectors: events, agriculture, fisheries, industry, offices, …

In France and abroad. 35% of turnover is realized from exports.


GELEC has, first of all, designed a range of simple electric generators that are reliable and meet the essential needs of the most frequent users, offering them contained investment costs and maintenance.

All of the production is constructed under ISO 9001 procedures and is marketed under three lines of industrial electrical generators, from 8 to 2,000 kVA, Diesel and soundproof, monophase or triphase, sharing a maximum of common normalized elements which keeps the sales price down and ensures facilitated maintenance.

GELEC Energy wanted to quickly be at the forefront of alternative energy solutions that use biofuels and energy storage to produce hybrid products that have a lower environmental footprint and that were also cost conscious.

GELEC Energy has joined the 2AST group

In July 2016, GELEC Energy joined forces with the 2AST group, which took a stake in the company, before buying it outright in 2018.

GELEC Energy thus becomes a subsidiary of the 2AST Group and enables its customers to benefit from the expertise and proximity of a national network (10 agencies spread throughout the country), for the installation and maintenance of its generating sets.

The 2AST Group has over 40 years of experience in the distribution, installation and maintenance of generators of all powers. Its prestigious references make it a key player in the sector.

The engineers in the design office located in Vernouillet, design and carry out customised grouping of large powers (up to 3000 kVA) as well as specific installations that meet the requirements of the most complex specifications.

The 2AST Group performs in various fields:

  • The study of your needs and your specifications;
  • Design and manufacture of specific equipment in our workshops in Plérin (GELEC Energy) and Vernouillet (ADV Altarès);
  • The sale and installation of new and second-hand equipment;
  • Rental of generator sets from 2.5 to 2500 kVA;
  • Maintenance and servicing.

To this day, the 2AST Group has over 100 employees.
