Our History

Since our founding in the United States in 1981, AES has driven energy sector growth and pioneered advances in many markets. Today we stand as a global energy industry leader in innovation and operational excellence with generation and distribution businesses across four continents.

AES first invested outside the United States with the acquisition of Kilroot Power Station in Carrickfergus, Northern Ireland, in 1992. AES expanded its presence in Northern Ireland in 2010 by acquiring Ballylumford Power Station on Islandmagee. We are the largest electricity generator in Northern Ireland, meeting 9.86% of energy demand across the All-Island electricity system in 2015.

​This Northern Ireland presence in complemented by a Great Britain based business development team focused on growing the business across the UK & Ireland, building on AES' global and local track record in energy storage, renewables, and thermal generation.

Today AES UK & Ireland, led by President Carla Tully, is committed to improving lives through the essential services we provide and the development of innovative solutions for this market, based on AES’ global experience.
