Ottovale coke works was a large industrial complex situated at Blaydon Burn, near Blaydon-on-Tyne, Gateshead, North East England.

[1] The heat was piped from the coke ovens to under four land-type Babcock & Wilcox boilers, each with 500 HP capacity.

The boilers supplied steam for two 275 kilowatt (kW) Parsons three phase turbo alternators.

[3] The station's boiler house and turbine hall were of a steel framed construction, with corrugated iron cladding.

The advantage of this type of construction is that if the coke ovens were to be abandoned, the station could be deconstructed and re-erected somewhere else at a minimal cost.

[6][7] In 1919 the station was further modified, becoming the first station in the world to use an enclosed ventilating circuit for the alternator with a gilled-tube cooler for extracting the heat from the ventilating air, which overcame problems caused by dust and moisture getting into the windings.
