IEEFA Australia: Afraid of the dark and clutching at coal, ESB still beating the capacity mechanism drum

Energy Security Board claims Dunkelflaute is a key reason for a capacity mechanism – where is the evidence?

The Energy Security Board (ESB) has cited periods of scarce wind and solar resources as a key reason to implement the contested capacity mechanism, which will see payments from energy consumers to primarily conventional power generators for their capacity to generate electricity, rather than for actually generating electricity. The ESB has claimed the market is […]

IEEFA Australia: ‘Race to replace’ – We need to tie new energy capacity with the exit of old generators

There are many options to manage the energy transition that don’t involve capacity payments

Uncertainty in the national electricity market is driving investment risk, due to high levels of uncertainty around coal exits, short term market contracting, early mover disadvantage in power technologies subject to deflation, and unpredictable government intervention, among other things. The Energy Security Board’s capacity mechanism has been proposed as a solution to these challenges. It […]

IEEFA Australia: There’s a better way to manage coal closures than paying to delay them

Energy Ministers and the energy industry should reject the ESB capacity mechanism proposal

21 September 2021 (IEEFA Australia): The Energy Security Board’s (ESB) proposal for consumers to pay conventional generators such as coal and gas an extra fee for their capacity, not just the actual power they produce, should be rejected by Energy Ministers at a forthcoming meeting this Friday argues a new report prepared by energy market […]

IEEFA Australia: The Energy Security Board’s dubious modelling

The capacity payment modelling doesn’t actually model a capacity payment

Australia’s Energy Minister Angus Taylor has been keenly promoting to media outlets that consumers will save $1.3 billion dollars from a proposal that will require those consumers to pay conventional power generators not just for the actual electricity they produce, but also an extra fee for the size of their power plants’ generating capacity, irrespective […]

IEEFA Australia: Hit to power bills from coal bail-out plan

Energy Security Board’s unnecessary $2.9 - $6.9 billion payment for power station capacity will come at a high cost to consumers

20 August 2021 (IEEFA Australia): Households may soon face a new charge on their power bills – potentially double that from the carbon price – if Energy Ministers agree to a proposal for a new capacity payment to power companies, according to a new report prepared by the Institute for Energy Economics and Financial Analysis […]

IEEFA Australia: ESB reform of electricity system needs to plan for a zero-emissions future

IEEFA's submission to the ESB post 2025 electricity market design options

Australia has a huge opportunity to become one of the first countries to fully transition to a zero-emissions electricity system. The nation stands to benefit financially by exporting technologies and know-how developed through the transition. The Energy Security Board (ESB) post 2025 market design process seeks to reform how the electricity system operates to integrate […]

IEEFA: Zero to 60% in 14 years – South Australia’s success in transitioning to renewables

Seven important lessons for energy planners around the globe in transitioning grids from fossil fuels to renewables

3 June 2021 (IEEFA Australia): South Australia offers vital lessons for other jurisdictions transitioning from a fossil fuel-based electricity grid to a low emissions, high renewables grid, finds a new report by the Institute for Energy Economics and Financial Analysis (IEEFA). “The proportion of South Australia’s electricity demand met by large scale and small scale variable […]

IEEFA Australia: Coal plant closures imminent as renewable energy surges

Several coal power plants in the National Electricity Market likely to be financially unviable by 2025

24 February 2020 (IEEFA Australia): Several of the 16 coal power plants in the National Electricity Market (NEM) will be financially unviable and at least one is likely to face closure several years sooner than planned due to coal plants’ poor flexibility and inability to adapt to a rapid influx of renewable energy, finds a new […]

IEEFA Australia: Energy Security Board reforms need to be ambitious to secure a low emissions future

ESB reform direction updated to incorporate stakeholder feedback and state government renewables investment schemes

The national electricity market (NEM) is in a state of flux. According to the Australian government’s Energy Security Board (ESB), over 60% of existing thermal generating resources (mainly coal) in the NEM are likely to exit over the next two decades as Australia transitions towards renewable generation (mainly wind and solar) and storage. This transition […]

IEEFA: Australia should be a net-zero emissions leader

Setting a target of net-zero emissions by 2050 would maximise employment, investment and export opportunities

11 December 2020 (IEEFA Australia): Australia must align itself with the global push to go carbon-neutral to maintain strong trade in a net zero emissions world, the Institute for Energy Economics and Financial Analysis (IEEFA) notes in its submission in support of a new climate change bill before the Australian parliament. The bill, introduced by Zali Steggall, […]
