The Glenamoy and Darthogue solar farms have planning permission for 32MW and have the potential for future expansion to 220MW.
Energia will develop the projects, which are the first solar acquisitions under the group's five-year €3bn ‘Positive Energy’ renewables investment programme announced earlier this year.
Energia head of corporate development Garrett Donnellan (pictured, right) said: “This is a very important agreement for Energia as it marks our first large-scale solar generation project.
“Earlier this year we announced our ‘Positive Energy’ investment strategy and commitment to help Ireland meeting its climate change and carbon reduction objectives.
“This announcement is part of that programme and an illustration of our intent.
“We have invested in these projects as they are in-line with our strategic objectives as a green energy provider and they offer the potential for future growth that will deliver for our customers, the communities we serve and broader corporate commitments.”
