Chamber Hall Power Station, Bury

The original installation had three Clarke, Chapman and Co boilers and two 2.1 MW turbine alternators. The turbines were of the Zoelly type made by John Musgrave and Sons, and drove Siemens Brothers Dynamo Works alternators. There were also two 500 kW motor generators to supply DC power, made by GEC.
