High retail prices, a state-wide blackout, and a shift away from coal-fired power – In the wake of these challenges to the security and reliability of energy supply in Australia, COAG Energy Ministers commissioned an independent review of the National Electricity Market led by Chief Scientist, Dr Alan Finkel AO. The final report leaves open some key issues that will potentially impact investors’ capital investment decisions.
Australia is in the process of transitioning to a lower emissions economy, but this shift comes with challenges for energy security and reliability. The Independent Review into the Future Security of the National Electricity Market (the Finkel Review) was commissioned by the Council of Australian Governments (COAG) to address these challenges and provide recommendations for overcoming them. A preliminary report was released in December 2016 and was followed by a consultation period, during which submissions were made. The final Finkel Review was released to COAG today.
The preliminary report did not contain recommendations, but highlighted key issues that needed to be addressed to ensure the future security of the National Electricity Market (NEM), including:
- The ‘energy trilemma’ of balancing security and reliability, affordability and reduction of emissions.
- Integration of new technologies that could improve reliability and security of supply.
- Transition to a low emissions economy and the achievement of Australia’s commitments to the emissions reduction targets under the Paris Agreement.
- Enhanced integration of variable renewable electricity generation and the provision of frequency control services as traditional sources of generation decline.
- Rising costs, in particular rising domestic gas prices that have rendered some gas-fired generators uneconomical.
- A market design that incentivises investment while maintaining security and reliability.
As readers will be aware, climate change has been a policy area that is fraught with danger in Australian politics. Just prior to the release of the preliminary report in December, the Federal Environment Minister Josh Frydenberg announced that the Government would consider an emissions intensity scheme (EIS) for the electricity sector. The Minister was then forced to revoke his comments within 36 hours due to internal party pressures.
Since the release of the preliminary report, the Government has maintained its position against an EIS. Attention has instead been focussed on a low emissions target (LET) scheme. The Labor Party and the weight of the business community supported an EIS, but have expressed a willingness to back a LET as a “second-best” option in the interests of Australia taking some positive action to tackle climate change.
Labor has said it will support a LET because it is easily “scalable”, meaning the scheme variables could be adjusted in the future (ie. under a Labor Government) to accelerate the emissions outcome and to meet further international targets.
The Finkel Review is principally about energy security and is wide-ranging in its scope and recommendations. However, the issue that has been attracting the most attention prior to the release of the Finkel Review has been the possibility of introducing a LET. This client alert focuses on the recommended LET component of the Finkel Review and its potential impact on the electricity generation sector.
The key aspects of the Finkel Review on how to achieve a “low emissions future” for Australia are set out below:
- The Finkel Review concluded that a Clean Energy Target (CET), in essence a LET mechanism, will provide the lowest impact on power prices to consumers while achieving the modelled emissions reductions, and was therefore the preferred policy approach.
- A CET would operate in a similar way to the existing RET certificate regime. Eligible low emissions generators will receive certificates for electricity produced, and electricity retailers will then purchase these certificates in order to meet their compliance obligations under the CET.
- A CET is ultimately preferred over an EIS due to ease of implementation, as it can readily be built on the model of the existing Renewable Energy Target (RET). It is also because the current high cost of domestic gas makes gas-fired generation an expensive alternative to coal for baseload and intermediate generation. A CET will provide a more gradual exit of coal-fired generation that under an EIS.
- A CET will set a target for the electricity generation sector to reduce carbon emissions by 2030. The Finkel Review noted a reduction of 26 to 28 per cent by 2030 (assessed against 2005 levels) as a minimum. This would be consistent with Australia’s general commitments under the Paris Agreement, but many commentators had expected the electricity sector to bear a much larger brunt of Australia’s obligations. Ultimately the reductions target is left for the Government to determine.
- A CET will be technology neutral, unlike the RET which applies only to generation from renewable sources. Instead, eligibility will be determined by an emissions intensity threshold. The threshold will be a measure of carbon intensity for electricity generation, measured as kgs of carbon per MWh of generation.
- Where the threshold is set will determine what generation technologies qualify as low emissions technologies. A baseline of 700kg/MWh will exclude all current coal-fired generators, but may potentially include them in the future if carbon capture and storage was to become viable. Most gas-fired generators are likely to be eligible. However, the Finkel Review does not recommend a specific emissions intensity threshold. Instead, that decision is left to the Government.
- CET will have an additional dimension to the RET (which allows one certificate to be created for each MWh of eligible generation). The lower the emissions intensity of the generator, the more CET certificates the generator will be entitled to receive.
- Unlike an EIS, generators who are above the emissions intensity threshold will not face a compliance cost. However, they will not be eligible to receive low emissions certificates (and earn the related revenue stream). This will impact the competitiveness of the respective generation technologies in the NEM.
- A CET should continue indefinitely, but there may be a limit on the number of years for which an individual generator is eligible to receive CET credits (the Finkel Review modelled 15 years).
- New generators will also be subject to reliability standards that may require wind and solar plants to install battery storage or arrange the installation of new back up generation (this support cannot be contracted from existing installed capacity). This will increase the cost of developing renewables. Different reliability standards may be set for different NEM regions.
- Large generators will be required to provide 3 years’ advance notice of closure, to mitigate security shocks from the exit of large generation capacity.
