Excerpt from the Annual Renewable Energy Constraint and Curtailment Report 2018 by Eirgrid
"EirGrid and SONI are the Transmission System Operators in Ireland and Northern Ireland respectively. We have prepared this report on the dispatch-down of renewable energy in 2018, as required under European and national legislation. In Ireland and Northern Ireland renewable energy is predominantly sourced from wind. Other sources include hydroelectricity, solar photovoltaic, biomass and waste. These latter sources of energy are generally maximised in dispatch and due to their small overall contribution to renewable energy,they are excluded from the report.
Dispatch-down of wind energy refers to the amount of wind energy that is available but cannot be produced. Dispatch-down due to overall power system limitations is referred to as curtailment. Dispatch-down due to a local network limitation is referred to as a constraint.
Wind Dispatch-Down in 2018
In 2018, the total wind energy generated in Ireland and Northern Ireland was 11,076 GWh, while 707 GWh of wind energy was dispatched-down. This represents 6% of the total available wind energy in 2018, and is an increase of about 321 GWh on the 2017 figure In Ireland, the dispatch-down energy from wind resources was 457 GWh; this is equivalent to 5% of the total available wind energy. In Northern Ireland, the dispatch-down energy from wind resources was 250 GWh; this is equivalent to 9.4% of the total available wind energy."
This is what RED WoLF is trying to target.
The presenation "Managing Curtailment in 2030" by Paul Blount & Rory Mullan from October 2019 will give a deeper insight. We are very thankful that Paul Blount and Rory Mullan agreed to make their presentatation available to the public.
