A Coordinated Strategic Reserve to Safeguard the European Energy Transition

In Germany and beyond, various capacity mechanisms are currently being discussed with a view to improving the security of electricity supply. One of these mechanisms is a strategic reserve that retains generation capacity for use in times of critical supply shortage. We argue that strategic reserves have specific advantages compared to other capacity mechanisms in the context of the European energy transition. To date, however, the debate on capacity mechanisms has largely been restricted to national contexts. Against this background, we discuss the feasibility and potential benefits of coordinated cross-border strategic reserves to safeguard electricity supply and aid the energy transition in Germany and neighboring countries at large. Setting aside strategic reserve capacity which is deployed only in the event of extreme supply shortages could improve the security of electricity supply without distorting the EU’s internal electricity market. In addition, overall costs may decrease when reserve procurement and activation are coordinated among countries, particularly if combined with flow-based market coupling.

Flexible Short-Term Power Trading: Gathering Experience in EU Countries

Abstract EU power market design has been focused on facilitating trading between countries and for this has defined interfaces for market participants and TSOs between countries. The operation of power systems and markets within countries was not the focus of these developments. This may have contributed to difficulties of defining or implementing a common perspective in particular on intraday and balancing approaches. This motivated us to pursue an in depth reviewof six European power markets to contribute to a better understanding of the common elements, differences and the physical and institutional reasons for these. With this paper we aim to present the main insights emerging from the reviews and to identify where there is a need for alignment of operational aspects and short-term trading arrangements, taking into account system requirements individual member states face in operating their power system.

Power Market Design beyond 2020: Time to Revisit Key Elements?

We revisit key elements of European power market design with respect to both short term operation and longer-term investment and re-investment choices. For short term markets, the European policy debate focuses on the definition of common interfaces, like for example gate closure time. We argue that that this is insufficient if the market design is to accommodate for the different needs of renewable and conventional generation assets and different flexibility options. The market design needs to ensure resources are pooled over larger geographic areas, the full flexibility of different assets can be realized with complex bids and scarce network resources are efficiently used. For investment and re-investment choices we argue that different technology groups like wind and solar versus fossil fuel based generation may warrant different treatment – reflecting different level of publicly accessible information, requirements for grid infrastructure, types of strategic choices relevant for the sector and share of capital cost in overall generation costs. We discuss opportunities for such a differentiated treatment and implications for electricity consumers.

A new EU energy technology policy towards 2050 : which way to go?

Each semester the THINK project publishes two research reports based on topics proposed by the European Commission.

A strategic energy technology policy towards 2050: no-regret strategies for European technology push

As current policy frameworks are expiring in 2020, the EU is revisiting its energy technology policy for the post-2020 horizon. The main long-run objective for energy technology policy is to foster the achievement of ambitious EU goals for decarbonisation by 2050. Given this objective, we discuss how European energy technology policy towards 2050 can be effective despite i) uncertain carbon prices, ii) uncertain technological change and iii) uncertain or alternating policy paradigms shifting its focus from decarbonisation to competition or security of supplies. Public support to innovation in energy technologies is needed to correct for market failures and imperfections, as well as to fully exploit trade opportunities of such technologies on the world market. Benefits from EU intervention can be expected from the coordination of national policies. Effective European technology push should put strong emphasis on pushing consumption-oriented and enabling technologies, as these offer a no-regret strategy vis-a-vis any future context.
