(180Mw)used a Central Unit Control system with the Turbine/Hydrogen cooled Alternators manufactured by GEC ,again No3 Alternator was a prototype direct water cooled.The coolant water being fed via Glass tubes on the 3 phase connections.Each unit had boilers manufactured by John Thompson of Wolverhampton, each using 2 Suction Ball Mills each with 2 Exhausters, these feeding to 12 front wall pulverized Fuel burners .The boilers fed steam at 900psi/900 deg F directly to each Turbine/Alternators of GEC manufacture

This was the largest Generating Station in the NW region at the time of completion in the 1958 to 1960 period .
