New Generation: Building a clean European electricity system by 2035

This study explores the least-cost pathways to a clean power system in Europe, compatible with the Paris Agreement climate goals (1.5C). Detailed, country-by-country, hour-by-hour power system modelling confirms the feasibility of almost completely decarbonising Europe's power sector by 2035, while expanding the electricity supply. Key metrics are quantified in order to benchmark progress, while accounting for a range of uncertainties. Crucially, the costs of competing routes are assessed, including the costs of developing the power system according to current plans. This report summarises the results of three modelled pathways for the European power sector. The Stated Policy pathway is aligned with stated national policies until 2035. The other two pathways -- Technology Driven and System Change -- are computed to minimise cost while remaining within a carbon budget compatible with the Paris Agreement climate goals. The latter two pathways expand clean electrification, but differ in their assumptions about available technologies and the levels of energy savings resulting from societal change
