Company History

In 2010, M.O.E. was accredited according to DIN EN 45011 by the national accreditation body (DAkks) as the first company in the field of grid integration of renewable energies. In the same year, M.O.E. received a final authorization from the VDE (FNN) and the FGW. In the year 2010, M.O.E. could already confirm a successful refitting of more than 3 GW wind power carried out by inspections and system certificates. Thereby, we significantly contributed to a stable supply of power through renewable energies. We occupy the chairman’s seat of the most relevant committees and tightly collaborate with the leading manufacturers from the renewable energy industry.
