摘要：Cross-border trade remains a contentious issue in the restructuring of the European electricity market.
Difficulties stem from the lack of a common market design, the separation between energy and
transmission markets and the insufficient coordination between Transmission System Operators (TSOs).
This paper analyzes the cross-border trade problem through a set of models that represent different degrees
of coordination both between the energy and transmission markets and among national TSOs.
We first present the optimal organisation, not implemented in Europe, where energy and transmission are
integrated according to the nodal price paradigm and Power Exchanges (PXs) and TSOs are integrated.
This is our reference case. We then move to a more realistic representation of the European electricity
market based on the so-called market-coupling design where energy and transmission are operated
separately by PXs and TSOs. When considering different degrees of coordination of the national TSOs’
activities, we unexpectedly find that some arrangements are more efficient than the lack of coordination
might suggest. Specifically we find that even without a formal coordination of the TSOs’ counter-trading
operations, non discriminatory access to common counter-trading resources for all TSOs may lead to a
partial implicit coordination of these TSOs. In other words, an internal market of counter-trading resources
partially substitutes the lack of integration of the TSOs. While a full access to counter-trading resources is a
weaker requirement than the horizontal integration of the TSO, it is still quite demanding. We show that
quantitative limitations to the access of these resources decrease the efficiency of counter-trading. The
paper supposes price taking agents and hence leaves aside the incentive to game the system induced by
zonal systems.
