What’s the frequency Kenneth? Rapid Eirgrid Management (REM) on a high wind system

Last week saw the Irish Wind Energy Association’s (IWEA) spring conference, and far from being the end of the world as we know it, the sector feels fine.

On 14 March, the sector set yet another record with 55% of that day’s electricity coming from wind generation. The overall possible instantaneous penetration of non-synchronous generation, Non-Synchronous System Penetration (SNSP), now stands at 60%. As Eirgrid noted at the conference and other similar forums, they are managing a relatively isolated system with the world-leading proportion of wind generation. Meanwhile the Generation Capacity Statement (GCS), government policy and industry forecasts all point to continued growth in variable renewable generation.

This week’s blog compares wind output against system demand, interconnector flows and overall generation on three dates.
