Four French groups are the main tenderers in the great majority of cases: Dalkia (Veolia Group), Elyo (Suez), Cofathec
(GDF) and Soccram (Thion-Ne Varietur Group).
Gaz de France also proposes withdrawing from heating network activities in France, currently conducted through its Cofathec
subsidiary - without, however, abandoning its close ties with Soccam, France's 4th largest heating networks operator.
The European Commission has approved the acquisition by French heating, ventilation and air conditioning systems company Cofathec
of a 50% stake in Climespace, another French firm currently solely-owned by Elyo.
