O’Connor was the last commercial miller to operate in Cushendall and realised that small mills were no longer sustainable, so he decided to change his business from milling to generating electricity. In association with the D.S. Electric Company in Belfast, he formed the Cushendall Electric, Light & Power Company and placed six lights between St Mary’s Roman Catholic Church and the start of Mill Street, one on High Street, four along Shore Street, one at the Cushendall Hotel on Bridge Street and three along the road to Waterfoot. Water from the mill race at Mill Street powered a 15 BHP water turbine that was directly connected to a 10kW generator. The new lighting scheme placed Cushendall firmly in the 20th century, ahead of towns like Bangor, which only lit their streets in 1930.
