A planning application for a 22 turbine onshore wind farm in North Mayo has been submitted to An Bord Pleanála.
Developers SSE Renewables and FuturEnergy Ireland claim the Glenora facility could generate 158MW or enough energy to power 115,000 homes a year when operational.
The construction of the project would also result in up to 120 jobs being supported.
The development is a 50:50 joint venture between the companies.
"The Mayo region and the north-west is home to immense renewable energy resources which could play a significant role in delivering Ireland's climate targets ahead of 2030," Tom Coleman, Development Project Manager for SSE Renewables.
"However, for projects like Glenora Wind Farm to deliver to their potential, investment in grid infrastructure in the north-west is critical."
"We look forward to working with Government and EirGrid to address grid challenges in the region and unlock the potential of the north-west."
An application to An Bord Pleanála to connect Glenora Wind Farm to the national grid is expected to be submitted in the second half of 2024.
The decision to submit the planning application follows a period of consultation with local resident and neighbouring communities.
"Extensive community consultation and in-depth environmental studies have helped to inform the design of Glenora Wind Farm," said Emmet McLaughlin, Project Manager at FuturEnergy Ireland.
"We are pleased to incorporate this feedback and submit the planning application for this project, which comes at a time when Ireland is in urgent need of renewable energy."
