Winds of change: Analysing SEM wind forecast accuracy - tmrw. test

Winds of change: Analysing SEM wind forecast accuracy

Following the publication of the Tomorrow’s Energy Scenarios (TES) 2019, we can expect to see greater penetration of wind generation in the coming 20 years, with installed capacity forecast between 6.0GW to 8.2GW by 2040. As the growth in wind generation continues, forecasting wind accurately will become increasingly important in order to balance demand and supply in the SEM. In this week’s blog, we analyse EirGrid’s wind forecast against actual generation over the past two years.

All-Island wind dispatch-down rises year-on-year

On 17 September, EirGrid published its Annual Renewable Energy Constraint and Curtailment Report 2019 which sets out the amount of wind and, for the first time, solar energy, that is available but cannot be used by the system (i.e. the dispatch-down of energy). Overall, the dispatch-down of energy from wind in Ireland...
