With the rising focus on integrating high shares of renewable energy into energy supply systems, the need to meet the viability of these renewable sources becomes pressing. Apart from storing electricity in electrochemical storage units, the concept of sector coupling could promise to provide the needed flexibility and storage capacities. A strong metric is needed to determine the viability and economic feasibility of different sector-coupled energy systems. This conference study presents an empirical method to develop a list of key performance indicators (KPIs), as a direct adaption of the KPI of the energy system with a single energy vector is not always possible. The list was developed based on a stakeholder workshop within the H2020 research project E-Land. The authors proposed the introduction of three new indicators for the evaluation of sector-coupled energy systems, namely degree of autonomy, levelised cost of energy and degree of sector coupling. A sector-coupled case study is evaluated to validate the performance of such new indicators while proving their utility to better assist decision-making.

Despite large amounts of readily available renewable energy (RE), island states in the Caribbean are still heavily dependent on mostly imported fossil fuels for their energy production. Making use of empirical analyses, this paper explores the barriers to the development of RE for power generation in the Caribbean, and outlines a strategy of how to overcome these barriers. Semi-structured interviews with three "super-experts" serve to supplement the findings of a preceding literature review. Approximately 30 experts are consulted to confirm and rank the identified barriers to RE according to their importance. The end-product of this study is a ranking matrix that will serve as a strategy instrument for decision-maker, who are then able to prioritize barriers and initiate their removal.

The concept of sector coupling promises to provide flexibility for rising renewable shares. A strong metric is needed to determine the viability and economic feasibility of different sector coupled energy systems. A direct translation of key performance indicators (KPI) commonly used for single vector systems is not always possible. The KPI proposed have been developed based on a stakeholder workshop within the H2020 research project E Land.
