This report investigates the potential future need for and role of two of the main dispatchable renewable power sources available in Europe – CSP equipped with thermal storage and dispatchable hydropower (dam and pumped hydro). The generated data – which will subsequently be fed into two different modelling frameworks in the MUSTEC and SCCER JA IDEA consortia – describe the policy pathways of a set of European countries. These policy pathways consist of all (actual or possible) near- to mid-term policy decisions that affect the need for power system flexibility, either by increasing it (e.g. more fluctuating renewables) or reducing it by providing flexibility (e.g. dispatchable sources, storage, interconnections). Each pathway is centred around a certain logic – a worldview, or belief about the type of policies that are (to its proponents) acceptable and beneficial, leading to a distinct type of electricity future.
