Spurred by the economic crash in 2009 and facilitated by our EASA membership; Shermco Industries of Irving, Dallas Texas became the inspiration for our initial move into the Wind Generator Repair market. Subsequently, this led to changing our business to a more lean and digital approach.

In 2015, Campbell Electric Motors, Dublin was acquired by the Avonmore Group making Avonmore Electrical the exclusive distributor of ABB Low Voltage Motors in Ireland.


2018 marked our 60th year in business. The historic day – Tuesday, 22nd May 2018 – was 60 years since our founder Jerry Sheehan first opened the doors of Avonmore Electrical to the public.

To mark this tremendous achievement, we opened our doors to the public once more, this time in the form of our Reliability Engineering Showcase and Open Day. Coupling informative reliability themed seminars, presented by 9 of our expert global partners, with open house tours of our workshop, meant each of our 150+ engineering guests were treated to an afternoon of reliability engineering at its finest.
