HumeLink Transmission Line Achieves Considered Project Status

Strategic Insights -

The new 500 kV HumeLink transmission line, a significant project aimed at unlocking an additional 3,000 MW of renewable energy into the grid, has reached considered project status under the National Electricity Rules (NER). Once completed, the project will facilitate the connection of the Snowy Hydro Scheme expansion project, Snowy 2.0, which will provide 2,200 MW of on-demand energy into the grid, sufficient to power three million homes for a week. HumeLink will also enable the direct connection of solar and wind generators, as well as battery and pumped-hydro energy storage facilities to the NSW transmission network, promoting a more reliable and sustainable national electricity grid.

Key Takeaways:

  • The HumeLink transmission line, anticipated to unlock 3,000 MW of renewable energy, has achieved considered project status under the National Electricity Rules (NER).
  • Upon completion, the project will facilitate the connection of the Snowy Hydro Scheme expansion project, Snowy 2.0, providing 2,200 MW of on-demand energy into the grid.
  • HumeLink will enable the direct connection of 365 kilometers of new transmission lines and new or upgraded infrastructure at four substation locations.
  • The project is expected to deliver more than $1 billion (USD 650 million) in net benefits for consumers by providing access to more sustainable and affordable energy to homes and businesses.
  • Transgrid is committed to supporting customers to achieve connection to HumeLink as quickly and efficiently as possible, helping meet renewable generation and emissions reduction targets.
  • Renewable energy generators and energy storage facility proponents are encouraged to start discussions with Transgrid to enable direct connection to HumeLink and support electricity generation growth and reliability.

Statistics:

  • 3,000 MW of renewable energy to be unlocked into the grid through the HumeLink transmission line.
  • 2,200 MW of on-demand energy to be provided by Snowy 2.0, sufficient to power three million homes for a week.
  • $1 billion (USD 650 million) in net benefits expected to be delivered to consumers through the project.
  • 365 kilometers of new transmission lines to be constructed as part of the project.
  • Four substation locations to be upgraded or equipped with new infrastructure.
