Downer completes Molonglo substation to support future ACT energy connections
Downer completed full turnkey design, construction and commissioning of Evoenergy’s new 132 kV Molonglo Valley zone substation. The work integrates IEC 61850 protection, control and communications. The substation adds network capacity for future customer connections, including BESS, but the announcement does not report a battery installation.

Reported scope and milestone
Downer completed full turnkey design, construction and commissioning of Evoenergy’s new 132 kV Molonglo Valley zone substation. The work integrates IEC 61850 protection, control and communications. The substation adds network capacity for future customer connections, including BESS, but the announcement does not report a battery installation.
Engineering interpretation
The completed asset is a grid substation that enables later connections, not a BESS project itself. Integration of IEC 61850 protection and communications is significant because future connection capacity depends on coordinated control and network interfaces at the 132 kV node.
Delivery responsibilities
An EPC reference defines a contracted combination of engineering, procurement and construction. Its boundaries still matter: field facilities, pipelines and utilities may be one package within a larger development. Construction affiliates and specialist subcontractors retain their stated roles. Quality records, pressure tests, pre-commissioning and handover need to match the actual facilities delivered. A historical project schedule does not become a publication date or establish today’s production. The reference documents the listed work rather than attributing all output, ownership or operation of the wider development to the contractor.
