Glenorchy Landfill Gas Power Plant
Grid-connected, renewable, distributed generation
Location: Glenorchy, TAS
The site
AGL has undergone development of a build-own-operate landfill gas extraction and power generation facility at Glenorchy’s Jackson Street Landfill, Tasmania. Methane-rich gas is produced from decomposing municipal waste within the landfill. The landfill gas is extracted and combusted to generate electricity.
Technology
The gas is extracted from the landfill through an array of wells interconnected by a network of buried pipes. A blower is used to actively draw the landfill gas into the extraction system. Adjustments made to the blower and the individual wells facilitate the efficient operation of the extraction and combustion system.
Energy purchase and supply
At full capacity the plant is expected to produce approximately 14 GWh of electricity a year. The generator operates 24 hours, seven days a week and is accredited under the Mandatory Renewable Energy Target (MRET) Scheme, Green Power Scheme and is currently seeking approval to be an accredited generating system under the NSW Greenhouse Gas Benchmark Scheme. The generation facility is connected to Aurora Energy’s Distribution Network at 11 kV. AGL has the rights to the gas extracted from the landfill, and power generated from the project is sold to Aurora Energy under a long-term agreement.
Environmental impact
The project is expected to save about 50,000 tonnes of greenhouse gas emissions per annum (the equivalent of removing about 11,600 cars from the road) by utilising landfill gas that would otherwise escape into the atmosphere and by offsetting fossil fuel-fired electricity generation.
“As a member of the Cities for Climate Protection program (CCP), Glenorchy City Council is committed to achieving environmental excellence and has surpassed our corporate goal to reduce greenhouse gas emissions by 70 per cent on 1997 levels by 2010. The joint venture with AGL Energy Services has been a great success at the Jackson Street Landfill to provide gas power generation to achieve the Five Milestones of the CCP program. We have reduced the impact of our landfill on the environment by enhancing an excellent biosustainable product in the form of electricity.”
