The site will span a 600-acres near Rochfortbridge.
Plans are due to be lodged with Westmeath County Council for a €1 billion data centre campus and solar farm.
The project by Red Admiral DC Ltd and owned by Offaly businessman Nigel Reams, will span a 600-acre site near Rochfortbridge.
It includes a six-unit data centre and a decentralised energy resource, using advanced solid-oxide fuel cells.
A 410-acre solar farm is also part of the proposal, with the firm seeking a 10-year planning window for the development.
The application follows a ruling in May by An Coimisiún Pleanála that the project is not classified as Strategic Infrastructure Development, placing the decision with the local authority.
Paul Collins, Operations Director at Lumcloon Energy says this development would attract 'home grown talent' from the midlands:
