Representatives from electricity grid operator TransGrid visited Tumut on Thursday as part of a new round of community consultation on the proposed Humelink 500-kilovolt transmission line.

Transgrid head of corporate affairs Graeme Wedderburn said Wagga would sit between Humelink, running to Snowy Valleys, and the new Project EnergyConnect line to South Australia.

"If EnergyConnect and Humelink are approved by the regulator to be built, it will centre two of the grid's most important transmission lines in Wagga, basically," he said.

"And so Wagga becomes in a sense the centre of the national electricity market.

"Humelink is considered essential because of the need to get more of the electricity out of the southern shared network, and that includes the expansion of the Snowy 2.0 project...it's needed to transfer electricity to customers all over the state, including at Wagga and Tumut and Adelong."

TransGrid will hold "face-to-face" community meetings this month at Wagga, Tumut, Yass, Gundagai and Goulburn over Humelink's proposal to link substations in Wagga, Bannaby and Maragle.

The potential routes, which would see new transmission towers up to 65 metres tall, run on both sides of Batlow between Tumbarumba and Tumut.

Mr Wedderburn said Thursday's meeting at Tumut was about setting the agenda for future community consultations.

"We're here to listen to the community, to hear their views and their ideas and their issues in connection with project Humelink," he said.

"The purpose is not to focus on any particular issues..it's really to listen to local people about a range of issues.

"This is the first opportunity we have had to meet face-to-face because of COVID."

Mr Wedderburn said TransGrid had planned to hold community consultations earlier in the year but delayed them because of the Dunns Road Bushfire.

Wagga MP Joe McGirr told NSW Parliament earlier this month that he had been contacted by residents from Yaven Creek, Kyeamba Valley, Adjungbilly and Batlow over an "absence of face-to-face consultation" that was not justified by pandemic restrictions.

Dr McGirr said on Thursday that he was meeting with "affected landowners and TransGrid representatives" and would "be in a better position to comment after that meeting".
