Close to half of NI electricity demand over the past year was supplied by renewable sources, according to figures from the Department for the Economy.

For the 12-month period from October 2021 to September 2022, 49.3% of NI’s total electricity consumption was supplied by local renewable sources. This is a significant increase on the 42.1% for the previous 12-month period, although it is still slightly behind the highest proportion ever recorded in the 12-months to September 2020.

In February 2022, over 76% of electricity consumption was generated from renewable sources, which is the highest monthly proportion on record.


Wind energy remains the dominant source of renewables in NI, accounting for nearly 85% of renewable generation. Around 6% came from biogas, 4% from biomass and 3% from solar PV.

Under NI’s path to net zero energy strategy, 70% of electricity consumption must come from a diverse mix of renewable sources by 2030.
