To help manage energy demand for one of Australia’s fastest growing communities in Western Sydney, we provided program management services and high-level technical advice.

Integral Energy was the second largest state-owned energy corporation in New South Wales (NSW). In 2011, the NSW Government sold Integral’s retail division to Origin Energy and Integral’s network division was renamed Endeavour Energy, which currently spans over 24,500 km2 over the Greater Western Sydney, the Illawarra, and the Southern Highlands districts of NSW.


Its distribution network serves more than 2.1 million people and includes approximately 28,000 substations, connected by 315,000 power poles and 33,000 kilometres of lines and cables.



Integral Energy commissioned WSP to provide program management services and high-level technical advice for multiple Demand-Side Management (DSM) programs within its network division.


We improved demand and energy efficiencies at the Wetherill Park Industrial Area, with a reduction of 260 tonnes of CO2 and the deferral of a new zone substation for three years.


Powering Growing Communities

Integral Energy, now renamed Endeavour Energy, continues to safely deliver power to some of Australia’s fastest growing communities, including Western Sydney.
