Gas starts flowing from AGIG’s 440 km Tanami pipeline

Australian Gas Infrastructure Group (AGIG) says it has commissioned Australia’s newest major natural gas pipeline project ahead of schedule.

The 440 km Tanami Natural Gas Pipeline was recently given the final signoff to start operating by the Northern Territory Government. It will fuel the power stations at Newmont Mining’s Tanami gold mine in the Northern Territory.

AGIG’s Chief Customer Officer, Andrew Staniford, said: “We have now commissioned the pipeline and gas is already flowing into Newmont’s Tanami mine site.”

Staniford said the final go-ahead for the pipeline to move into full operational mode followed the introduction of gas and extensive commissioning and testing of the pipe and the facilities at the pressure under which the pipeline will operate. Operations were initially expected to start up in the March quarter.

“These tests were successfully undertaken by AGIG and independently verified, thereby enabling the final approval to be given,” he said.

AGIG was, last year, awarded the contract by Newmont to build, own and operate the new 440 km pipeline, which transports gas to the Newmont mine site, about 540 km northwest of Alice Springs, in the Northern Territory.

Staniford said: “To deliver the project safely and ahead of schedule for Newmont and its operating gold mine is a feather in the caps of all involved and has further cemented AGIG’s proud position as a leading provider and operator of key energy infrastructure throughout Australia.”

The new NT pipeline follows the alignment of Tanami Road and passes through a mix of pastoral land, Aboriginal freehold land and Crown land.

Newmont’s Tanami underground gold mine produced 419,000 oz of gold (attributable to Newmont) in 2017.

South32 powers up Cannington solar PV farm

The new 7,200-panel solar farm at South32’s Cannington silver-lead mine in northwest Queensland, Australia, is up and running, the mining company confirmed.

The 6 ha, 3 MW installation is the company’s first solar installation and will help to deliver reduced greenhouse gas emissions by offsetting gas consumption with solar. Construction commenced in May.

“Electricity generated from the farm will be used to supply the operation’s accommodation village and airport with surplus power used to support mining and processing operations,” South32 said.

The project – which contributes to the objectives of the company’s Climate Change Strategy – is the second largest solar installation in a remote, off-grid mining operation in Australia and the first to be integrated into a gas-fired power station, according to the company.

Earlier this year, EDL Energy signed a 14-year extension of its contract to supply electricity for Cannington, which included partnering with SunSHIFT, a wholly-owned subsidiary of engineering and construction firm Laing O’Rourke, to ‘hybridise’ the existing 34 MW gas plant at the site, with this 3 MW solar photovoltaic installation.

It is anticipated the new solar farm will prevent between 4,000-6,000 t/y of greenhouse gas emissions.

Rob Jackson, Vice President Operations at Cannington, said the operation was committed to identifying energy efficiency initiatives. “Reducing greenhouse gas emissions is a big part of that so I’m delighted that our Cannington operation’s solar installation is leading the way,” he said.

The cost to install and operate the solar farm will be offset by lower fuel costs, according to South32. This makes it an economically viable solution for the operation.
