Once installed, they are set to be the largest capacity turbines onshore in Ireland, according to Windpower Intelligence, the research and data division of Windpower Monthly.
Construction of the 10.2MW site is set to start this month, with commissioning expected in H2 2018.
The award of the contract marks the first time Innogy and SGRE have worked together on an onshore project in more than a decade, the companies said.
Innogy announced it planned to expand its renewables portfolio and enter new energy markets when it was floated on the Frankfurt Stock Exchange in November 2016. It opened an office in Dublin in January.
Innogy Renewables Ireland managing director, Cathal Hennessy, said: "We plan to grow our onshore wind business to include greenfield developments and consented sites right through to the acquisition of operational wind farms."
