A gas pipeline through Merriwa and Denman is being proposed by Eastern Star Gas.
The company has already held one-on-one consultations about property access with some landowners in those areas.
Community information sessions will be held at the end of the month to explain the proposal.
Eastern Star hopes to get state and federal government approval by the middle of next year for a pipeline from Narrabri to a proposed liquid natural gas facility in Newcastle.
The company expects to lodge their completed environmental studies within three months.
The pipeline would be just over half a metre in diameter and 286 kilometres long.
One section would pass near Merriwa and to the east of the Goulburn River National Park, cross the Hunter River 1.5 kilometres east of Denman, continue south of Lake Liddell near the Bayswater and Liddell power stations and on through Derring, Mitchells Flat, Elderslie and Stanhope.
At a proposed liquefied natural gas terminal at Newcastle’s Kooragong Island, the gas would be frozen to shrink it for transport to Asia.
The gas would also be available to be used by gas-powered stations built near the pipeline.
A gas pipeline could reignite moves toward another base-load power station between Singleton and Muswellbrook, The Singleton Argus reported last week.
“Macquarie Generation has one of the most promising opportunities for gas-fired power generation in NSW and Eastern Star is geographically well placed if the project was to proceed,” Eastern Star spokesman Peter Fox told The Singleton Argus.
Macquarie Generation has state government “concept approval” for a new coal- or gas-powered Bayswater B station in addition to the existing two stations, Liddell and Bayswater.
