Nov 24, 2025 10:25 AM ET
  • Hydro Tasmania seeks up to 1,500 GWh/year from large-scale wind and solar via long-term offtakes, diversifying hydro, meeting rising demand, and securing bankable, affordable low-emissions power for Tasmania's grid.

Hydro Tasmania, the state-owned utility, launched a solicitation for up to 1,500 GWh a year of renewable generation via a commercial offtake agreement. The company is seeking supply from large-scale wind or solar projects, aiming to lock in additional output to cover rising electricity needs across Tasmania.

The planned offtake would diversify Hydro Tasmania’s predominantly hydro portfolio and provide long-term revenue certainty for new projects. The move signals accelerating demand on the island’s grid and a push to secure affordable, low-emissions power. Further details on contracting terms and timelines were not disclosed. The tender seeks bankable, long-term supply contracts.
