The roots of Danish Management Group go back to 1986, when Mr. Frantz Longhi founded Dansk Energi Management, which started implementing major energy projects in Denmark. The company focused primarily on designing, planning and implementing Renewable Energy and Energy Efficiency projects in Denmark, where successful energy projects for approximately EUR 75 million were implemented in the first couple of years.

Since Dansk Energi Management gradually became more involved in international energy projects, the company name was changed to Danish Energy Management.

In the beginning of the nineties, the company conducted feasibility studies, assessments and energy action plans and supervised several Energy Project Management Units on behalf of the European Commission in several Central and Eastern European countries. Since then, the company has expanded its scope of operations as well as the geographical boundaries.
