The initial plant installed at the power station consisted of two Brown Boveri 5 MW turbo alternators with two Babock & Wilcox cross type marine water tube boilers.

The power station building was constructed of brick except for one end wall which was clad in galvanised sheeting to allow for future expansion.

This boiler was also built by Babcock & Wilcox and was a bi-drum radiant type water tube boiler and ran at a steam pressure of 415 pounds per square inch (2,860 kPa) with a capacity of 50,000 pounds (23,000 kg) of steam per hour and was fed by a single Babcock "Detroit" Rotograte stocker.

At its peak the power station had a capacity of 13.222 MW and provided electricity to 17 mines and to Teralba, Barnsley, Estelville, Wakefield, West Wallsend, Killingworth and Cessnock.

Soon afterwards a connection with the J & A Brown Richmond Main to Hexham transmission line was made to interconnect the output of the two power stations.
