New provisional data from EirGrid shows that 48% of electricity came from renewable sources in October, up from 43% in September and 45% the same time last year.
Eirgrid said that a significant amount of October’s renewable electricity was generated by windfarms, accounting for 40% of the electricity used in Ireland last month.
Total generation from wind energy amounted to 1237 gigawatt hours (GWh) compared to 1015 GWh in September.
Today’s figures show that grid scale solar made up around 4% of the fuel mix, with gas generation accounting for 38% and 13% imported via interconnection.
The overall electricity system demand stood at 3101 GWh, up from 2857 GWh in September.
Up to 75% of electricity can be generated from renewables at any one time, with plans to increase this to 95%.
Diarmaid Gillespie, Director of System Operations at EirGrid, said today’s figures mark another positive indicator of the progress the country is making towards a more sustainable electricity grid.
“As we would expect at this time of year, we also saw an increase in demand for electricity as we head into the colder months and darker evenings. We have recently released our Winter Outlook which shows that the risk of insufficient generation being available to meet demand is now notably lower than it has been in recent years,” he stated.
“As demand for electricity continues to grow and generation sources are increasingly from renewable sources, we remain focused on both operating the grid of today and preparing for the grid of tomorrow,” he added.
