Coal Power Closure Extensions Stir Government-Energy Sector Tension

The proposed system allowing state governments to request temporary extensions for power station closures has triggered a response from the energy industry, alleging that it could dampen incentives for renewable energy investment. Despite coal's historical dominance in Australia's energy landscape, its usage is declining rapidly, with projections from the Australian Energy Market Operator indicating that traditional generators will exit the system within the next 15 years.
However, Australia faces challenges in replacing coal-fired power stations, as developers encounter difficulties in securing transmission access, face cost overruns, and encounter opposition from local communities. These challenges have sparked concerns that coal plants could shutter before adequate alternatives are available.
The profitability of coal generators is diminishing, particularly with the surge in solar generation, causing many generators to incur losses. Nonetheless, profits soar during peak demand periods when solar generation declines. However, the rise of battery storage poses a threat to the profitability of coal generators, as batteries offer cheaper running costs and reduce evening demand.
The absence of sufficient replacements could result in unreliable electricity supplies and significant price hikes, with New South Wales (NSW) facing a particularly urgent situation. Negotiations between the NSW Labor government and Origin Energy to extend the lifespan of the Eraring coal power station, slated for closure in 2025, underscore the pressing need for action.
To address potential issues, state and federal governments are contemplating the implementation of an Orderly Exit Management (OEM) Framework. This framework would empower participants to adjust closure dates, providing them with special powers to navigate the transition. Currently, coal power station owners and operators must adhere to a three-and-a-half-year notice period before closure.
However, the Australian Energy Council, representing electricity and gas companies, has called for a reevaluation of the OEM scheme, citing concerns that it could undermine signals for renewable energy investment. The framework introduces significant uncertainty and risk into the equation, potentially deterring investment in renewable energy projects at a critical juncture in the energy transition. Moreover, the potential for generators to delay activating the framework and the lack of transparency regarding the commercial terms shielding thermal generators from market price signals could exacerbate long-term uncertainty for renewable energy investors.
The discourse surrounding the OEM framework reflects the complexities of Australia's energy transition. While the federal government has set ambitious targets for renewable energy generation, the nation risks facing blackouts and price hikes if new renewable energy sources are not developed expeditiously. Extending the lifespan of coal power stations presents a political challenge, given coal's unpopularity among voters, particularly in urban areas.
The NSW government's decision to pursue an extension for the Eraring power station has encountered opposition from environmental groups. To mitigate criticism, the government has opted to keep negotiations out of the public spotlight, navigating the delicate balance between energy security, environmental concerns, and political considerations.
