摘要：The horizontal integration of the energy market and the organization of transmission services remain two open
issues in the restructured European electricity sector. The coupling of the French, Belgian and Dutch electricity
markets (the trilateral market) in November 2006 was a real success that the inclusion of Germany to the
trilateral market should soon prolong. But the extension of market coupling whether in Central Western Europe
or in other European regions encounters several difficulties and the future remains far from clear. The highly
meshed grid of continental Europe complicates things and it is now sometimes recognized that the penetration
of wind will further exacerbate these difficulties. The nodal system could go a long way towards solving these
problems, but its implementation is not yet foreseen in the EU.
This paper analyzes versions of market coupling that differ by the organization of counter- trading. While
underplayed in current discussions, counter-trading will become a key element of market coupling as its
geographic coverage expands and wind penetration develops. We consider a stylized six node example found in
the literature and simulate market coupling for different assumptions of zonal decomposition and coordination
of TSOs. We show that these assumptions matter: market coupling can be quite vulnerable to the particular
situation on hand; counter-trading can work well or completely fail depending on the case and it is not clear
beforehand what will prevail. Our analysis relies on standard economic notions such as social welfare, Nash
and Generalized Nash equilibrium. But the use of these notions is probably novel. We also simplify matters by
assuming away strategic behaviour. The nodal organization is the reference first best scenario: different zonal
decompositions and degrees of coordinations are then studied with respect to this first best solution.
