Abstract: 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. JEL: D47, L51, Q48

This paper summarises the findings of work package 5.3 of the SECURE project, with regard to the role of carbon capture, transport and storage (CCTS) for the future European supply security of coal. The real issue in European supply security with respect to coal is the absence of an economically and politically sustainable use of coal for electricity, liquefaction, gasification, etc. Whereas earlier papers delivered for work package 5.3 on the coal sector indicated that there are few risks to the European energy supply of (steam) coal, there is an implicit supply security threat, i.e. that coal will no longer be an essential element of European energy supply because the CCTS rollout will be delayed or not be carried out at all. This thesis is substantiated in this subsequent paper, with more technical details and some case study evidence.This Working Document is a follow-up to the SECURE project, financed by the European Commission to study the "Security of Energy Considering its Uncertainties, Risks and Economic Implications".
