Intermittent renewable generation is increasingly displacing conventional generation units, i.e. traditional suppliers of balancing services, from the daily electricity dispatch. As a consequence, there is a growing need that renewable generators also contribute to electricity balancing so that system operational security is guaranteed at all times. Nevertheless, current European market designs limits the handling of renewable production intermittency through efficient intraday trading and, in several cases, prevent renewable power producers from participating in active and passive electricity balancing. In this respect, the European Commission, together with ACER and ENTSO-E, has developed guidelines for the harmonization of national electricity markets, aiming at eliminating cross-border barriers and facilitating the integration of massive amounts of renewable generation. Although these guidelines establish general principles for the future design of the European electricity market, there are several open issues regarding the most adequate arrangements leading to an efficient integration of renewable production in electricity markets. In this context, this thesis critically analyzes European market arrangements affecting electricity balancing, identifying relevant barriers and providing recommendations for the design of competitive and efficient intraday and balancing markets.
