Fast-response energy storage systems (ESS) are emerging as a viable alternative for the
electrification of island power systems, providing energy arbitrage and ancillary services that
reduce system cost and create room to accommodate additional renewable energy. Besides
the operational benefits attributed to the presence of storage, the contribution of the ESS to
the overall capacity adequacy of the system remains an issue open to investigation, that
becomes ever more important in view of the withdrawal of thermal generation in the way …
