An efficient cross-border investment and well-designed markets and regulatory instruments are crucial prerequisites to the creation of a fully functional European internal electricity market. One of the prominent regulatory measures taken to speed up the creation of the internal market was to abolish tariff pancaking by replacing cross-border tariffs with an Inter-Transmission System Operators Compensation (ITC) mechanism through which transmission system operators (TSOs) can compensate each other. In this study, the implication of introducing such mechanism on the cross-border investment outcome is explored. The results indicate that the current ITC mechanism is loosely linked to the cross-border investment decisions of TSOs. In addition, the study concludes that factors such as the ITC fund size and the number of participating TSOs can influence the investment outcome.
Traditional analysis of distribution network tariff design assumes a lack of alternatives to grid connection for the fulfilment of consumers' electricity needs. This is radically changing with breakthroughs in two technologies: (1) Photovoltaics (PV) enable domestic and commercial consumers to self-produce energy; (2) Batteries allow consumers and self-producers to gain control over their grid energy and capacity parameters. Contributing to the state of the art, the grid cost recovery problem for the Distribution System Operator (DSO) is modelled as a non-cooperative game between consumers. In this game, the availability and costs of the two named technologies strategically interact with tariff structures. Four states of the world for user's access to technologies are distinguished and three tariff structures are evaluated. The assessed distribution network tariff structures are: energy volumetric charges with net-metering, energy volumetric charges for both injection and withdrawal, and capacity-based charges. Results show that in a state of the world with new technology choices for grid users both efficiency and equity issues can arise when distribution network charges are ill-designed.
Nowadays, the European electricity systems are evolving towards a generation mix that is more decentralised, less predictable and less flexible to operate. In this context, additional flexibility is expected to be provided by the demand side. Thus, how to engage consumers to participate in demand response is becoming a pressing issue. In this paper, we provide an analytical framework to assess consumers' potential and willingness to participate in active demand response from a contract perspective. On that basis, we present policy recommendations to empower and protect consumers in their shift to active demand response participants.
