The online retail giant plans to build a 115MW wind farm in Ardderroo to help offset the energy consumption of its data centres in the country.
The wind farm project joins two others in Cork, which will come online in September 2020 and Donegal, to follow in early 2022.
These three wind farms will add 229MW of renewable energy to the Irish grid each year.
They are also forecast to reduce carbon dioxide emissions by 366,000 tonnes every year and producing enough renewable energy to power 185,000 Irish homes.
In an announcement, Amazon said: “We have committed to offtake 100% of the power from these projects without relying on public funding. As a result, we were the first organisation in Ireland to sign unsubsidised Corporate Power Purchase Agreements (CPPAs).
“We started this with our two existing wind projects, in Cork and Donegal, in 2019, and continue today with our third and largest CPPA to date with the new project in Galway.
“These three Amazon renewable projects help Irish energy consumers avoid an estimated €229M Public Service Obligation (PSO) subsidy cost on their energy bills.
