Vales Point was originally equipped with three turbo-alternators of 200 MW supplied by
English Electric (unit nos. 1 to 3) and one of 275 MW supplied by
Associated Electrical Industries (unit no. 4), for a total of 875 MW. The first two units were completed in 1963, and the third in 1964. Unit no. 4 was brought into use in 1966. In order to supply coal to the station, three mines were opened; Chain Valley Colliery, Newvale No.1 Colliery and Wyee State Mine. These four units were known as 'A' Station, its capacity of 875 MW being the highest in New South Wales at the time. Vales Point 'A' Station was decommissioned in 1989. The turbines were removed in 1997; the boilers and buildings were demolished between 2011 and 2014. ==B station==
