Evoenergy is continually planning for the future and securing the ACT and region's energy supplies.
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.
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.
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.
Civic Zone Substation, Firth Rd to Edinburgh Avenue, Acton
Evenergy is commencing capital works for the construction of a new 11 kV cable feeder from Civic Zone Substation, Firth Rd Acton to Edinburgh Avenue, Acton to supply new residential and commercial developments in the Canberra CBD. The project will be delivered in two stages. The first stage from the Zone Substation to Clunies Ross Street is proposed to be completed by June 2019 and the second stage from Clunies Ross St to Edinburgh Avenue Nishi building is proposed to be completed by September 2019.
Stage one is expected to have minimal impact on road and pedestrian traffic in the area. Stage two may cause some disruption to traffic along Parkes Way, but Evoenergy will work to minimise such impact.
