7.30pm.

Pump trucks are on site and are removing thousands of litres of water from the zone substation on Little Collins Street.

We’ll continue to work through the evening to remove all the water and will begin damage assessments and any repairs immediately after the water is gone.

We have also made more progress restoring power for customers by switching them to other parts of the network.

As of 7.30pm there are 1149 customers off supply, down from 10,000 earlier this afternoon.

Our teams are working through the night to continue to restore power to more customers and repair damage to equipment as quickly and safely as possible.

We appreciate it’s difficult to be without power for any length of time and we thank all of our customers who may be affected by this outage for their patience.

5.30pm.

A burst water main has flooded a public car park at 32-60 Little Collins Street, with water entering a zone substation located in the basement of the facility.

For safety, we have turned off power from the site, which supplies about 10,000 customers in the south-eastern sections of Melbourne’s CBD.

We have been able to restore power to more than 4000 customers by redirecting power supply from other parts of the network. There are currently about 5,700 customers off supply in the area.

Our crews are on site and working to remove the water. This will allow safe access to the zone substation so any damage can be assessed.

We will keep customers updated by SMS and on our website on restoration times.
