Proud to be Ireland’s largest provider of wind power

Our energy sources

At SSE Airtricity, we’re proud to supply Irish businesses with 100% green energy*.

In 2020, all of the electricity we supplied to our home and business customers was from renewable energy sourced by SSE Airtricity, abating over 131,000 tonnes of harmful CO2 emissions every month.^^

As well as supplying 100% green energy to more Irish homes and businesses than any other supplier, we’re also proud to be the largest generator of wind power in Ireland. SSE’s operational portfolio of 28 onshore wind farms has a combined generation capacity of over 700MW, making SSE the largest generator and provider of renewable energy in the all-island Single Electricity Market. This portfolio includes the 174MW Galway Wind Park, Ireland’s largest wind farm which is co-owned with Greencoat Renewables.

In addition to the renewable energy offtake from SSE plc’s fleet of wind farms, SSE Airtricity also has Power Purchase Agreements in place with third party renewable energy generators for over 300MW of wind and solar-sourced power on the island. Together, we can power the change to a greener Ireland.
