The Power Supply Upgrade Program is designed to ensure Sydney's rail network is able to meet expected power requirements to support future timetables and air-conditioned fleet. The program involves upgrades to substations, section huts, overhead wiring and feeders as well the construction of new infrastrucutre across the network.

The overhead wiring works consists of:
* Upgrade of 29 1500V DC electrical sections with 300 metres (minimum) auxiliary feeder
* Upgrade of 9 1500V DC electrical sections with 500 metres (minimum) auxiliary feeder
* Upgrade of 7 1500V DC electrical sections with 600 metres (minimum) auxiliary feeder
* Upgrade of 7 1500V DC electrical sections to a higher capacity system (eg existing System 9 to System 12) with allowance for up to 25% structural replacement

It is proposed that this work will be undertaken as a Design and Construct tender with Early Contractor Involvement. It is anticipated that a document will be issued to the market in September or October 2016.
