The New South Wales Independent Planning Commission has granted a two-year extension for Delta Electricity's Chain Valley colliery operations in the Lake Macquarie region, allowing coal extraction until December 2029. This decision comes despite warnings from the NSW Net Zero Commission, which stated that continued coalmine expansions are incompatible with the state's emissions reduction targets of 50% by 2030, 70% by 2035, and net zero by 2050. The commission justified the extension by arguing it would provide reliable baseload electricity during the transition to renewable energy sources. However, it explicitly prohibited the transport of coal for export or other domestic uses beyond supplying the Vales Point power station. The Greens climate spokesperson, Sue Higginson, criticized the approval as a narrow interpretation of emissions obligations, suggesting it could be challenged in court. Activist group Lock the Gate Alliance noted the decision sets a significant precedent for future mine assessments, as it is the first time the commission has banned coal exports from a project. Delta Electricity defended the decision, emphasizing its role in supporting local jobs and energy stability during the transition.
