Our journey to net zero

At Transgrid, we are leading the transition to a clean energy future. Our responsible delivery and maintenance of the NSW & ACT network is accelerating Australia’s energy transformation by creating more capacity for renewable energy generation and use.

Enabling Australia’s clean energy future is our biggest contribution to avoiding dangerous climate change. We also have a responsibility to deliver a fit for future electricity network that minimises climate impact in construction and operation.

Transgrid is building on its leadership in the energy transition by rolling out credible and ambitious long-term greenhouse gas emission (GHG) reduction targets.

These targets are science-based targets (SBT) aligned to the level of decarbonisation required to keep global temperature increases to 1.5 °C or well below 2°C compared to pre-industrial levels set by the Science Based Target Initiative (SBTi).

Cutting our direct emissions

The majority of our current direct emissions are produced from two sources, our petrol and diesel-powered vehicle fleets, and emissions of SF6, a greenhouse gas used in network equipment.

We plan to reduce our direct emissions by eliminating emissions from our passenger and commercial vehicle fleets by 2030, and supporting industry efforts to develop alternatives to SF6 use.

Cutting our indirect emissions

Most of Transgrid’s indirect emissions are from the additional electricity generation required when energy is lost during transmission as it moves along the network (‘transmission system losses’) which will decline as the grid decarbonises.

We are seeking to hasten this by accelerating the project program to enable Australia’s renewable energy transition. We are also developing metrics to better understand how our system security projects influence losses.

By 2025 we will purchase GreenPower accredited renewable energy for our offices and depots.

Cutting our value chain emissions

The major contributor to these emissions is our purchased goods and equipment, such as the steel and concrete that goes into our high-voltage transmission towers.

To drive efforts across our value chain we have committed that 50 per cent of our spend will be with suppliers that have Science-Based Targets by 2025.
