The irish “All Island Grid study” - Methodological approach and outcomes

This paper details the methodological approach and outcomes of the all island grid study, which aims to show the impacts of high penetrations of renewable energy in the Irish electricity system. Renewable generation portfolios with a share of up to 59 % of renewable energy were examined from the plant dispatch and network perspective as a 2020 snapshot study. The dispatch analysis of various scenarios of conventional generation revealed only minimal restrictions posed by the expected future conventional generation. The examination of network restrictions resulted in a feasible energy penetration of 42 %.
