I worked with EirGrid during 2002-2004 when discussions were underway about changes impacting grid operations based on the increased penetration of intermittent resources. Now Ireland and EirGrid are leading the way in showing how to operate a wholesale electricity market and keep the grid reliable through the use of Grid Services as the supply side resource mix evolves and greater precision in forecasting and the timely planning for grid services are critical survival skills for grid reliability.Â
