The three Siemens Gamesa SWT-3.4-101 turbines at the site in the south-west of the country are now operating and the project is in the final commissioning stages.
Innogy has also opened a new office in Kilkenny City in south-east Ireland, from where eight staff will explore opportunities for renewable projects in the country.
Innogy said it aims to acquire existing wind farms and develop new projects. It already has an office in Dublin on the east coast.
Cathal Hennessy, managing director of Innogy Renewables Ireland, said the company was "encouraged" by government support for auctions.
He added: "Innogy has considerable experience in competing in such support schemes and has seen significant successes in wind auctions in recent years in Europe. We aim to replicate this in Ireland."
In July, the Irish government approved a switch to an auction regime from 2019.
It added that it would need to procure the equivalent of 4.5GW of onshore wind to meet its target of sourcing 55% of its electricity from renewables by 2030.
