Approach

TEC-C was selected by Transgrid to deliver the complete design and construction scope for the Glenellen 300MVA 132/33kV solar farm substation, including the associated 132kV overhead connection works to integrate the project into Transgrid’s network.

TEC-C was also requested to accelerate delivery timelines to align with the client’s commercial commitments, which we achieved by being flexible and optimising workpackage delivery. The delivery required disciplined stakeholder management and careful interface planning, including working around existing distribution infrastructure, with the 132kV overhead line designed and constructed within the corridor of an existing 22kV Essential Energy overhead line.

Construction execution was driven by detailed planning and safe workface coordination across multiple parties, including coordination with third parties undertaking 33kV solar farm cabling works. Temporary power arrangements were implemented where required to protect warranties on fixed plant, and site-specific controls were implemented to manage dust impacts from adjacent works.

Outcome: The Glenellen substation was commissioned to the local Transgrid network, supported by an acceleration plan and programme discipline to minimise rework and maintain schedule certainty.
