Connecting Offaly to the national grid

Electricity in the county before ESB

Offaly had electricity before the establishment of ESB in 1927. ESB’s annual reports record 6 local electricity suppliers in the county — that means 6 individuals or companies who had permits to commercially supply electricity to 3 or more homes and businesses in their local area. The reports do not record when each local supplier was first established, merely the number of consumers they supplied, as well as the year the supplier was acquired by ESB.
