In this article we describe the strategic interplay of actors involved
in a tripartite relationship (supplier-distributor-end user), which a
im at maintaining or modifying each actor's position relative to the o
ther actors in the relationship and in the surrounding network, using
both direct and indirect action. In the case of energy distribution in
France (electricity and gas), certain specificities have to be taken
into account: the electricity supplier's monopolistic position and its
obligation to supply the service and the distribution centers' mixed
vocation (they propose two kinds of energy, gas from Gaz de France and
electricity from Electricite de France) and their obligation to distr
ibute both kinds of energy. On the basis of an analysis of ten relatio
nships between the Electricity Production and Transportation Division
and Energy Distribution Centers, we show the actor's search for an opt
imal distance between the supplier and the intermediary. According to
its own resources, the intermediary tries to deal with its own end-use
r market in an autonomous way or to use resources represented by the s
upplier and other actors in the connected network. Some managerial imp
lications concerning the management of supplier compulsory relationshi
ps with a differentiated approach are suggested.
