Third quarter of 2019 a big one for Irish wind industry.


Wind provided 29 per cent of our electricity in Q3 2019 as four new wind farms connect

The Irish Wind Energy Association, Ireland’s largest renewable energy organisation, today published its quarterly industry report for quarter three of 2019, covering July, August and September of this year. The figures show wind provided 29 per cent of Ireland’s electricity in quarter three. Four new wind farms, with a combined capacity of 181 MW were connected.

Dr David Connolly, CEO of the Irish Wind Energy Association, said: “The share of Ireland’s electricity powered by wind keeps rising and we’re on track for what could be one of our best year’s ever for completing new wind farms.

“Wind energy is an Irish success story. Every day it is driving down electricity costs for consumers, cutting CO2 emissions and guaranteeing this country real energy independence.”

New wind farms

Ireland’s wind fleet continues to grow with four new wind farms completed in this quarter, bring another 181 MW of renewable energy capacity online. The future pipeline is also growing and by the end of September five new wind farms with a combined capacity of 206.25 MW had got planning permission.

Dr Connolly continued: “If we are to hit our targets in the Climate Action Plan we need to be building and connecting wind farms at a record-breaking pace. We’re now confident we will break 4 GW of installed capacity by the end of the year but this leaves us only a decade to reach our 2030 objective of 8.2 GW.”

The 29 per cent share of electricity demand for quarter three amounted to almost 1.97 million MWh of electricity, compared to 1.57 million in the third quarter of 2018. The average Irish household uses approximately 4.2 MWh of electricity every year.

The total installed capacity of Ireland’s wind farms has now risen to 3,925 MW.

Key statistics

Wind energy’s share of electricity demand: 29% up from 23.4% in Q2 2018

Total amount of electricity generated by wind in Q3 2019: 1,973,000 MWhup from 1,569,000 MWh in Q3 2018.

Total installed wind energy capacity at end of Q3 2019: 3,925 MW.

Total new capacity installed: 181 MW.

Number of new wind farms built: 4.

Number of new wind farms to get planning permission in the first nine months of 2019: 5 with a total capacity of 206.25 MW.

Amount of wind energy dispatched down in Q3 2019: 157,793 MWh

Note to Editors

The figures in the IWEA Quarterly Report are based on data provided by EirGrid, ESB Networks, the SEAI and our own members. Some figures are provisional and may change as new data comes in.

A megawatt (MW) is a unit of power. A single megawatt is equivalent to around 1,000 kilowatts. Boiling a kettle, for example, takes around two kilowatts. 

A megawatt-hour (MWh) is a unit of energy. It is normally used to refer to the amount of electricity generated or consumed. A standard Irish household would use around 4.2 MWh every year.

Wind energy is ‘dispatched down’ when wind farms are instructed by EirGrid, as the system operator, to stop generating electricity.

This is typically done due to constraints on the electricity network – the transmission system is physically unable to carry more electricity from where it is being generated to where it is needed – or to ensure system stability.
