This model-based analysis complemented the narrative scenarios describing plausible visions of EU electricity markets and networks in the period up to 2050. Scenarios were derived using TU Wien’s Green-X model, a specialised energy system model with a sound incorporation of various RES policy approaches, closely linked to the open-source energy system model Balmorel, allowing to shed further light on the interplay between supply, demand and storage thanks to a high temporal resolution.
