Following significant debate about the provision of electricity undertakings across the Central Coast, including over the split between Erina Shire and Gosford, on 16 October 1942 Gosford Municipality combined with the Shires of Erina and Woy Woy to form the Brisbane Water County Council to provide electricity to the combined area of the three councils. The County Council operated as an electricity and gas supplier and retailer and was managed by representatives of the three councils. The County Council operated until its amalgamation with the Sydney County Council from 1 January 1980.
