Multi-million dollar upgrade for local substation

Multi-million dollar upgrade for local substation

Essential Energy will be undertaking a multi-million dollar upgrade of the Tumut power supply beginning in the second half of this year.

Essential Energy Regional Manager Southern, Steven Ilitch, said the purpose of the works is to ensure the electricity supply stays functional well into the future.

“Later this year, Essential Energy will commence a major upgrade of the existing 66,000-volt zone substation in Tumut as part of its ongoing commitment to improving the long-term reliability of the local power supply,” he said.

Zone substations convert high voltage power to a level which can be distributed throughout the community for use in homes and businesses. Tumut’s power is supplied from an existing 66,000-volt zone substation on the Snowy Mountains Highway which receives electricity from a 132,000-volt transmission powerline between Wagga Wagga and Yass.

Mr Ilitch said Essential Energy would take steps to ensure the upgrade would have a minor effect on residents.

“Preliminary works are scheduled to commence in October. Local residents may notice an increase in vehicle activity around the zone substation site once work begins, however, all work will be planned to minimise the impact on customers,” he said.

“This project will help us to ensure that the network is in peak condition and enable delivery of a safer, more reliable service for customers.

“A new 11,000-volt switchboard building will be constructed and a new 11,000-volt switchboard installed. The existing frequency injection control system and two aged transformers will also be replaced.”

The project will take two years to complete, and will involve the construction of new buildings and refurbishment of ageing infrastructure and equipment within the zone substation.

This year’s state budget set aside $1.654 million for the upgrade, with an expected spend of $4.190 million in total.
