Presentation of the company Gelec Energy

Performance, innovation and environment

Founded in 2013, GELEC Energy designs and assembles industrial diesel generator sets that meet the most demanding requirements for controlled investment and maintenance costs.

Continuous, emergency or safety power generation requires reliability and seamless adaptation to the needs of your installation. We have therefore designed a range of high-performance, durable professional diesel generators with great resistance to load impacts to suit different environments and sectors of activity: agricultural, industrial, construction, ephad and retirement homes, campsites, logistics platforms, mass distribution, events, etc.

From 10 to 2000 kVA, our industrial diesel generators are available in single or three-phase versions, enclosed (standard), open (without enclosure) or in containers.

The development of sustainable solutions has always been at the heart of the company’s strategy, as it is sensitive to environmental concerns. We therefore also offer a range of generator sets running on biofuel (B100) as well as new solutions for the future, which are currently under development.

At the end of 2021, we have just launched a new range: lighting masts that integrate a generator set, thus enabling the autonomous production of light.

GELEC Energy wants to go beyond the mere development of a high-performance generator by designing systems that meet today’s energy and ecological requirements. These are the challenges we try to meet every day!


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.
