The report presents the methodology and major results of the second phase of the FLEXNET project. This phase is focussed on identifying and analysing the options to meet the flexibility needs of a sustainable and reliable power system in the Netherlands up to 2050. More specifically, following the first phase report of the FLEXNET project (which focussed on identifying and analysing the demand for flexibility of the Dutch power system), the current report identifies and analyses the supply options to meet three different sources (‘causes’) of flexibility demand, i.e. flexibility needs due to (i) the variability of the residual load (defined as total power demand minus VRE generation), (ii) the uncertainty of the residual load (notably the lower predictability of VRE power output), and (iii) the congestion of the grid (in particular at the Liander distribution network level). A major conclusion of the analysis at the national level is that up to 2050 (hourly changes) in cross-border power trade is the most important option to meet the demand for flexibility due to the variability of the residual load in the Dutch power system (although the size of this option depends on the assumed interconnection capacity across European countries). At the Liander regional network level, a major conclusion is that the potential of flexibility options to avoid network congestion – and, hence, to avoid network expansion – is generally limited (although in specific cases the deployment of flexibility options may be an important tool to reduce the need for network expansion, either temporarily or structurally).
