Overall gas demand in Ireland increased by 5 per cent in July compared with June, according to the latest figures from Gas Networks Ireland.
July was the second hottest July since records began and one of the sunniest on record. The warm and sunny weather was accompanied by periods of low wind conditions, which meant a lower supply of wind energy.
Against this backdrop, demand for gas for the electricity generation sector increased by 10 per cent month-on-month, while gas demand from almost all other industry sectors fell during the month.
Gas accounted for 43 per cent of Ireland’s electricity generation in July, up from 40 per cent in June. Gas generation peaked at 70 per cent during the month and never fell below 21 per cent.
Wind accounted for 22 per cent of electricity generation, down from 30 per cent in June, while solar accounted for 9 per cent.
Gas Networks Ireland’s Director of Regulation and Strategy, Edwina Nyhan said:
“July’s figures demonstrate the important role gas continues to play in Ireland’s energy system. While it was an exceptionally warm, dry and sunny month, there were periods of lower wind generation, and gas remained a dependable source of electricity generation when it was needed.
As Ireland continues to diversify its electricity generation and increase the contribution from weather-dependent renewable sources, flexible gas generation will play an increasingly important role in maintaining a secure and reliable electricity supply. Gas-fired peaking plants can ramp up quickly when wind and solar generation dip and reduce their output again as renewable generation increases.”
