Abstract: This paper deals with the probabilistic evaluation of the long-term resource adequacy of an interconnected power system. An integrated software tool that solves the long-term scheduling problem using a sophisticated unit commitment model is employed, while both traditional capacity and flexibility adequacy concepts are addressed. A novel methodology to assess the flexibility adequacy using the operational power system schedule is presented. Multi-year simulations of the Greek interconnected power system on an hour-by-hour basis for the forthcoming 10-year study horizon (period 2018–2027) under a set of scenarios regarding the future operating conditions have been performed, providing the key operational data for the calculation of all probabilistic indicators. Test results indicate that the existence of all currently available thermal generating units as well as the timely realization of all scheduled construction plans is of utmost importance for the long-term secure and reliable operation of the Greek interconnected power system. In a more generalized framework, the ambitious EU goals regarding decarbonization and increasing RES shares in electricity generation should be accompanied by detailed studies in order to ensure that no resource adequacy problems will arise in the near future due to the massive withdrawal of conventional base-load and, possibly, flexible generating units.
