Renewables provided close to 40% of electricity in January
Electricity from renewable sources provided for close to 40% of total demand in January, according to provisional data from the transmission system operator EirGrid.
The majority of renewable electricity1 generated last month came from windfarms, which accounted for over 32.9% of all electricity used in Ireland. Total generation from wind energy amounted to 1,075 GWh (Gigawatt hours) over the month.
Overall, renewables provided 39% of electricity in January when other sources including grid-scale solar2 and hydropower are included.
Overall electricity system demand3 stood at 3,262 GWh for January.
Meanwhile, gas generation accounted for 45.1% of all electricity used, with 10.4% being imported via interconnection, 4.3% coming from coal, and the remaining 1.2% from other sources4.
About the data
1Average Fuel Mix is a representation of the System Generation fuel mix and net imports across the power system. The “Renewables” category includes wind, solar, hydro and biomass sources. It excludes some non-centrally monitored generation (e.g. small scale combined heat and power and microgeneration).
2Not including rooftop (embedded) solar.
3System demand represents the electricity production required to meet national electricity consumption, including system losses, but net of generators' requirements.
4The “Other” category includes Peat, Distillate, Combined Heat and Power (CHP), Aggregated Generating Units (AGUs) and Demand Side Units (DSUs). Waste is split 50% between the “Other” and “Renewable” categories.
