SoDa story

The SoDa Service originates from a European project funded by the European Commission in 1999. The SoDa project was led by Mines ParisTech.

SoDa is implemented in 2003 by Mines ParisTech and managed since 2013 by the research center O.I.E. of Mines ParisTech (Center Observation, Impact, Energy) which put every effort on the assessment and analysis of spatial and temporal aspects of renewable energies resources and the environmental impacts of energy systems.

The research center O.I.E. is a common laboratory (or structure) of MINES ParisTech and ARMINES. ARMINES, a structure created in 1967, is based on the concept of research-orientated towards the industry. With more than 600 employees at ARMINES (teaching scientists, research engineers, doctoral candidates, postgraduates, technicians, administrative personnel), they support research together with their colleagues from the schools in joint research centres from ARMINES/ Schools.

Since Apr. 2009, TRANSVALOR S.A., a French SME founded in 1984, is in charge of the commercialization and exploitation of SoDa, and participates to innovative research projects.

SoDa products are co-developed by the Research Center O.I.E. and Transvalor S.A.
