The amber alert issued today on the country's electricity system has been lifted.
The alert had been issued earlier today due to low levels of wind power being generated in the electricity system.
An amber alert acts as an early warning when there is the possibility that supply may not match demand.
EirGrid, which runs the national grid, also blamed low solar energy, and outages at a number of generators.
This was the first amber alert this year and came as new figures from the CSO showed a significant increase in the power consumed by data centres.
Data centres increased their power consumption by 31% in 2022 and now account for 18% of electricity used. In 2015, data centres consumed 5% of electricity used. The increase in electricity used was 400%.
This compares to a 20% overall increase in electricity consumption over the seven-year period.
Households reduced their consumption of electricity last year by 9%.
The median, or mid-point residential consumption of electricity fell by 12% last year compared to 2021.
Urban and rural residential users of electricity accounted for 28% of consumption while non-residential users made up 71%.
Large users, which include IT and cement manufacturers as well as bigger data centres, accounted for 27% of consumption last year, an increase of 20%.
Households cut electricity use, consumption by data centres up
