Providing cleaner, renewable energy† for your business

Our energy sources

SSE Airtricity has been harnessing our greatest natural resource for the past 25 years, providing cleaner, renewable energy† for homes and businesses across the country.

Between 2017 and 2021, all the electricity we supplied to the grid for homes and business customers was from renewable energy^ sourced by SSE Airtricit y, abating over 10.3 million tonnes^^ of harmful CO2 emissions.

SSE Airtricity is the largest provider of wind power in Ireland, with an operational portfolio of 29 onshore windfarms totalling a combined generation capacity of over 800MW. This makes SSE the largest generator and provider of renewable energy in the all-island Single Electricity Market. 

The 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.
