NSW Planning Commission Approves Controversial Coal Mine Extension
The New South Wales Independent Planning Commission has granted Delta Electricity a two-year extension for its Chain Valley colliery operations in the Lake Macquarie region, despite explicit warnings from climate experts that such expansions jeopardize the state's legislated emissions reduction targets.
First Major Test of New Climate Legislation
This decision represents the first coalmine development considered by the planning commission since the Minns government took office and the first assessment conducted under the state's new climate change legislation. The Climate Change Act enshrines specific emissions reduction targets into law, including a 50% reduction by 2030, 70% by 2035, and net zero by 2050.
The commission justified its approval by arguing the extension is necessary to support reliable baseload electricity during NSW's transition to renewable energy sources. In its published statement of reasons, the commission stated the two-year extension "represents the outer limit of what can reasonably be justified in NSW's policy context of working towards decarbonisation."
Climate Experts Raise Serious Concerns
The NSW Net Zero Commission had previously warned the Minns government that continued coalmine expansions or extensions were fundamentally incompatible with the state's climate legislation. Despite this clear warning, the planning commission proceeded with approval, arguing that because the Delta project would cease by December 31, 2029—just before the 2030 emissions reduction targets take effect—the project "will not be required to meet those targets."
NSW Greens climate spokesperson Sue Higginson strongly criticized this interpretation, calling it "a narrow and possibly erroneous interpretation of our state's targets and obligations to reduce emissions." She emphasized that "we are currently overshooting our 2030 emissions reduction target" and warned that "the idea that we can run blindfolded to 2030 and all of a sudden stop and somehow be in compliance with our emissions reduction target and obligations is erroneous."
Potential Legal Challenges and Precedent Setting
Higginson further warned that environmental defenders are likely considering legal challenges, stating that "the state's top legal minds are clear that any new coal is inconsistent with the current law, it is therefore highly likely that if tested this coal approval would be declared unlawful."
The commission's decision includes a significant restriction: it explicitly prohibits transport of the coal for export or any other domestic use beyond supplying coal exclusively to the Vales Point power station. Activist organization Lock the Gate Alliance noted this potentially sets an important precedent for other forthcoming mine assessments, including three major projects scheduled for commission review this year.
Lock the Gate NSW coordinator Nic Clyde stated, "For the first time the NSW Independent Planning Commission has placed an explicit ban on export coal sales from a project. This is an important step and reflects the growing pressure on decision makers to take the climate impacts from coalmining seriously."
Company Response and Economic Justifications
Delta Electricity welcomed the decision, emphasizing it would support "hundreds of local mining jobs" while "ensuring a continued, secure local coal supply to Vales Point Power Station." The company noted that the mine supplies approximately 50% of the power station's coal needs and "plays an important role in supporting reliable electricity generation and system stability in NSW during the energy transition."
A company spokesperson added that the mine was "committed to a range of measures to mitigate emissions associated with the extraction and production of coal" and argued that domestic coal supply helps "mitigate coal supply risks associated with international price shocks and logistical constraints, supporting a stable, reliable and affordable energy transition in NSW."
Balancing Multiple Considerations
The commission stated it had "considered issues raised in community submissions and expert materials, including concerns about air quality, traffic, subsidence, biodiversity, water quality, energy security, economic impacts and the contribution of greenhouse gas emissions from the project to climate change."
Ultimately, the commission determined that the time-limited nature of the approval was "consistent with NSW's decarbonisation strategy and the state's 2030 emissions reduction targets," creating a contentious decision that highlights the ongoing tension between energy security needs and climate commitments during the renewable energy transition period.
