Gas emergency

Evoenergy is continually planning for the future and securing the ACT and region's energy supplies.

Gold Creek Substation

In late November 2017 we began a project to install a new 11 kV underground cable feeder from Gold Creek Zone Substation Mirrabei Drive to Hamer Street Gungahlin. This work is essential to ensure Evoenergy meets the power demand of the growing Gungahlin Town Centre East.

The new 11 kV feeder will provide an additional 5.5 MVA of capacity to meet the needs of developments in the Gungahlin Town Centre East area including the new light rail network. The works include open trenching and directional drilling to enable the new cable feeder to be installed.

During the works we found damaged conduits that need repairing. This extra work has caused delay and the project will now be completed in May.
Along with our Civil Works Contractor, Shepherd Electrical, we are working to repair the damaged conduits along Anthony Rolfe Avenue.

The project team is taking all necessary precautions to mitigate risks with the work site and to preserve safety to pedestrians along Anthony Rolfe Avenue.

Stage 2 - August 2018

We’re installing a new feeder to supply residents with electricity and meet demand in the Gungahlin area. Our Civil Contractor, Utilstra, will be completing work by drilling and trenching along Hamer Street to the corner of Flemington Road. This work is expected to last four weeks. Traffic management will be in place to provide support in this area over the next month. We thank everyone for their patience while we work to keep the network reliable for the northern suburbs.

Lawson South Stage 2

Following a number of changes to the ACT Government Land Development Agency’s (LDA) development strategy for Lawson South Stage 2, Evoenergy is commencing detailed design work for the requisite undergrounding of both 132kV transmission lines and 11kV distribution lines around the Belconnen zone substation. Noting the variation to previously agreed works, we will continue to work with the LDA to support their new approach to market.

Molonglo zone substation

At Evoenergy, we understand the ongoing energy needs of the community. That’s why we intend to construct a new 132/11kV zone substation in Molonglo, so we’re ready to meet the electricity needs of the Molonglo Valley, in the future.

The substation will provide an additional 55MVA capacity, enough to supply more than 20,000 homes with electricity.

Molonglo Stage 1 - land acquisition and development application (DA) approval is underway, with completion of the Stage 1 construction in the next four to five years.

Optical Fibre replacement project

Evoenergy is installing optical fibre communications between our zone substations to improve system reliability and security standards. Five optical fibre wires have been installed, with one further cable still to be completed. This project involves replacing existing wires with new aluminium ones that contain optical fibre cores through the middle of the conductors on top of the towers.

As our network grows and customer base expands these security upgrades will allow us to get more out of existing assets, reduce costs and provide opportunities to diversify the grid. The works will also ensure we continue to meet reliability and security standards as set by the Australian Energy Market Operator (AEMO). The second stage is in progress, with remaining stages due for completion by the middle of 2018.

Renewable gas projects in the ACT

Hydrogen - Evoenergy is working with the Australian National University on a research initiative around three elements: producing hydrogen from excess renewable energy; hydrogen usage as a storage medium; and a renewable energy source that can be used directly or injected into the ACT gas distribution network. Evoenergy is also actively working with the industry bodies and ACT Government on a number of trials to facilitate introduction of Hydrogen in gas network and path to convert ACT gas distribution network to meet ACT Government’s net zero emission targets.

Biogas - Evoenergy is working on a business case for a pilot scheme to convert organic waste to biogas in an anaerobic digestor, to inject the renewable gas into the ACT’s gas distribution network, to capture C02 for reuse and to generate soil enrichment fertiliser as part of the contribution to a closed cycle carbon neutral economy.

Secondary electricity supply for the ACT

Having a second point of electricity supply into the ACT will supplement the existing major electricity supply point in northern Canberra and is an important part of ensuring a reliable and secure electricity supply to the ACT.

The first stage of the second point of supply to the ACT project involved the construction by TransGrid in 2013 of the 330/132 kV Williamsdale Substation in the south of the ACT. This substation has been connected to Evoenergy's network via two new 132 kV transmission lines to Evoenergy's Theodore and Gilmore substations.

To complete the second point of supply to the ACT project, the following works are proposed and will be completed by 2020:

Construction of a new 330/132 kV substation by TransGrid at Stockdill Drive, West Belconnen.
Construction by TransGrid of a new 330 kV transmission line from Stockdill Substation to Canberra Substation.
Reconnection by TransGrid of its 330 kV Upper Tumut - Canberra transmission line to Upper Tumut - Stockdill.
Reconnection by TransGrid of its 330 kV Canberra - Williamsdale transmission line to Stockdill - Williamsdale.
Construction by Evoenergy of a new 132 kV transmission line from Stockdill Substation to connect to its Canberra - Woden transmission line.

Subject to environmental approval, construction work will commence in the second half of 2018. Further information on this project can be found here or on the TransGrid website.

Transmission Network Service Provider TNSP

To accurately record network losses, and in compliance with regulatory requirements on metering, Evoenergy is adding metering at each zone substation.
