Abstract
The resilience of an energy system and especially the national electricity supply is a complex and multidimensional concept, which is receiving growing attention at a European level. In particular, the increasing risks of extended electricity supply disruptions and/or severe electricity price fluctuations are stressing the need for an assessment of the European countries’ electricity supply resilience. This paper proposes an elaborative multicriteria decision support methodological framework, based on three major resilience dimensions, namely: “resist”, “restabilise” and “recover”. In total, 35 European countries are evaluated and ranked according to their performance on 17 interacting evaluation criteria. The overall evaluation of the countries is established based on a synergy of two complementary multicriteria decision aid (MCDA) methods. Specifically, the Choquet Integral is approached and assessed as an importance indicator to properly accommodate and incorporate the interacting criteria into the value system, negating therefore their arbitrary effects on the final benchmarking. Simultaneously, a procedure based on the Simos method supports the robust elicitation of the Choquet capacities. All preferential information required for the implementation of the MCDA framework has been elicited from an expert, highly knowledgeable of the European energy system. This research work aims to support energy policymakers in Europe and provide guidelines and areas for improvement at a country level.
Highlights
Energy resilience is a multidimensional concept, increasingly establishing a prominent role in national and international policymaking
The analysis proposed through this paper falls in the recently studied context of interacting criteria (Grabisch & Roubens, 2000), which receives growing attention from researchers and practitioners in the field of multicriteria decision aid (MCDA) (Figueira et al, 2009; Grabisch et al, 2008; Greco et al, 2014)
In terms of the criteria modeling procedure for the electricity supply resilience evaluation, this paper extends the work of Gasser et al (2020), building upon the 11 indices proposed in that study
Summary
Energy resilience is a multidimensional concept, increasingly establishing a prominent role in national and international policymaking. As such, it affects all dimensions of sustainability, namely the economy, the society, the environment and the governance, and assures the high quality of life and wellbeing of citizens (Gatto & Drago, 2020). Resilience benchmarks are used to assess the progress of a country over a period of time and compare its performance against its peers (Gasser et al, 2020) Such focused assessments can have significant practical impact and drive socio-economic and political progress, influencing and driving the development of relative initiatives, policies and technological research (Siskos et al, 2014). The results of benchmarks and studies in the broader area of energy policy, and those issued by international organizations (WEF, 2020; IEA, 2020; WEC, 2020; REA, 2019), attract the interest of a variety of observers, including governments, energy agencies and citizens associations
