Statement of significance:

These stations have now been demolished except for one remaing stack . Although the stations are seen as historically and socially significant, they had little aesthetic or scientific significance. The stations were regarded as having little significance under the criteria of representativeness due to being of relatively common type. Much of the significance is due to the stacks. These are significant under the criteria of rarity, but also maintain the historic and social significance of the site by providing a visual focus and stimulus for evoking the local community's close historical and cultural association with the station.

Historical notes: Prior to 1950, the electricity supply industry in NSW consited of a number of State Government, Local Government and privately owned corporations, each responsible for power generation. The Electricity Commission of NSW was set up by act of parliment in May 1950. The Commission was set up to take over the generation and main transmission functions of electricity industry. In 1953 Wallerawang Power Station, which was planned by the Railways department, was transferred during construction phase to the Commission. Wallerawang A station began operation in April 1957 and was decommissioned in May 1986. This station consited of four 30MW units. The fourth unit being completed in 1959. All have now been demolished. Wallerawang B station began operation in January 1961 and consited of two 60MW units. The installation of the second unit in November 1961. B station was decommissioned in 1990. It has since been demolished. One A station stack remains due to its rarity of construction and social significance.

Assessment of significance

SHR Criteria a)
[Historical significance]
Wallerawang Power Station (including A & B Stations) is significant because of its role in the extension of the NSW integrated transmission system to the western coal fields. The station is alos significant as a major part of the rich tradition of industrial activity in the Lithgow region.
SHR Criteria c)
[Aesthetic significance]
Wallerawang A & B Stations originally contained several items which were significant because of their innovative industrial design, within the context of power generation technology. These were the precipitators and the coal weighers which were of an innovative, lightweight design. As these are no longer present in the Station, it does not retain the integrity of these attributes.
SHR Criteria d)
[Social significance]
Wallerawang Power Station is significant as a major regional employer, drawing employees from the western Blue Mountains to Bathurst. It also continues to provide indirect employment through supplying local industries and business with contracts, and supporting local coal fields with contracts for coal. Thirdly, the Station played a pioneering role in some areas of mid-20th century industrial reform and employee relations within the electricity supply industry. It can therefore be said to have social significance for a large group of past and present employees at alocal and regional level. Wallerawang Station, especially the stacks, can be said to have significance as a visually dominant element of the cultural landscape. The fact that it is a prominent lamdmark on the skyline for some distance, provides a visual focus and stimulus for evoking the local community's close historical and cultural association with the station.
SHR Criteria e)
[Research potential]
A full assessment of the equipment of Wallerawang A and B stations was not possible, as this study didnot commence until after the salvage contract for the machinery had been let. Some parts of the station were inaccessible due to asbestos removal in progress. Because of this no comprehensive statement of the scientific significance or research potential can be made. Because the station has a low significance assessment under the criterion of rarity, the potential of research on Wallerawang A & B stations, based on either documentary or physical evidence, to contribute to a major or important research questions is likely to be low.
SHR Criteria f)
The Stacks from A & B station are considered significant under this criterion. Wallerawang was the first station to utilise concrete, faceted stacks. At later stations, this type was replaced by more modern smooth, tapered stacks.
SHR Criteria g)
The station has a moderate significance under this criterion. Individual items of plant which represent well- preserved examples of their type are the compressor house and the control room panels, including baily meters.
Integrity/Intactness: One A station stack remains intact.
Assessment criteria: Items are assessed against the PDF State Heritage Register (SHR) Criteria to determine the level of significance. Refer to the Listings below for the level of statutory protection.

Recommended management:

A maintenance strategy of inspection and repair is undertaken on the remaining stack.
