NSW - Queensland Interconnectors

Works will include replacements to existing transmission towers and poles and the rolling out of new transmission lines. Much of the work will occur in the New England region of New South Wales, which has been earmarked as a future Renewable Energy Zone by the state government.

TransGrid will also upgrade the substations at Tamworth, Dumaresq, Armidale and Muswellbrook, which will manage the expanded electricity transfers while providing further improvements to reliability.

TransGrid expects to ramp up construction works for the upgrades shortly, with the expanded network capacity coming online in the second half of 2021.
