Based on the Larzac plateau, in the heart of Aveyron, MJ2 Technologies is a major player in the small hydroelectricity market. Strongly linked to its territory, MJ2 displays a workshop of 2000m² and 200m² of offices.
Nowadays there are more than 100 VLH, 25 PMGA generators as well as a number of Kaplan + PMGA configurations in operation.
MJ2 Technologies thus appears as the major French player for the development and manufacturing of turbogenerator groups.
A French patent application has been filed for the VLH turbogenerator unit in 2003 as the outcome of many years of experience in the design of low-head turbines. This patent has been given an international extension in 2006. In April, 2004 MJ2 Technologies SARL was founded in order to develop the new concept, to find funding and manage the whole project from the scientific, R&D and industrial point of view with the aim of creating the first prototype.
In 2004 and 2005 preliminary studies had been completed. In 2006, laboratory tests on small scale models had a positive outcome thus confirming the technical performances, leading to the creation of the first demonstration site in Millau, in the south of France.
On March 19, 2007 the VLH group delivered its first kW to the public network on the Troussy site in Millau. This day marks the end of the first phase of R&D and thus the beginning of the VLH concept.
The VLH in Millau has now accumulated more than 35.000 hours of operation.
Since the commissioning, the Millau demonstration site has had more than 700 visits.
Experts from all European countries, as well as from North America, Latin America, and Asia have made a trip to Millau.
MJ2 has been delivering 35 VLHs by mid-2013 and should deliver other 7 turbines by the end of the year.
At the same time, MJ2’s international sales network displays representatives in Germany, Italy, Belgium, Spain, Holland, Poland, Canada and USA (foreign representatives). Agreements are being negotiated with other countries.New developments based on the experience feedback of the first VLHs have been integrated within the concept of next machineries to be built. The VLH concept is nowadays at its 4th version.
MJ2 Technologies is in its full industrialization phase. It should address new challenges: costs levels, reliability, multi-group site and island operation mode are among our next main goals.
On December 20 2012, the Italian group Sorgent.e, already present within the ownership of MJ2 from 2006, acquired 51% of the share capital. It is now the majority shareholder. This group is present in all of the renewable energies fields, both in Europe and abroad and it offers to MJ2 an important financial support within this stage of development as well as a number of commercial synergies, mostly in Latin and North America. Such smooth entrance has been executed respecting the existing team and guaranteeing sustainability and autonomy to MJ2.
In 2015, MJ2 Technologies acquired PMGA, a company founded in 2011 and French specialist in permanent magnet electric generators. With such new skills, MJ2 Technologies decided at the same time to develop its own blades profiles with the aim of being able to independently offer a range of Kaplan turbines. A new page in the history of MJ2 was written in 2016 with the manufacturing of 2 1800 kW pit turbines each associated to medium voltage permanent magnet generators.
Nowadays, new perspectives are arising with the development in new markets such as those of tidal applications…
