How did we get here?

• Electricity supply has been tightening as existing, fully depreciated coal

fired power stations close

• Policy uncertainty holding back new investment
• This has resulted in higher-cost, gas-fired generation setting the price

more often

System security and reliability: How did we get here?

• Renewables were pushed into

the system without:

• a focus on where they were

located

• a plan to replace inertia and

frequency response lost as coal closed

• a plan to deal with intermittency
• Investment uncertainty outside
• f renewables
• Lack of planning and sufficient

notice of major closures

Finkel Review

• Commissioned on 7 October 2016, through the COAG Energy Council,

after the state-wide blackout in South Australia

• 392 submissions
• 50 recommendations covering
• Increased security
• Future reliability
• More affordable power
• Greater gas supply
• Stronger governance with new Energy Security Board

15

“Australia hasn’t a moment to lose now that we have a comprehensive, independent blueprint to restore the security, reliability and affordability of

• ur electricity system”

Stakeholder views

Stakeholder views

“This is not a plan to make our power sector cleaner or our climate safer. It’s a short term political fix to deal with the fact that the people who are apparently responsible for running the country have an ideological attachment to dirty fuels.”

Finkel package – Increased security & reliability

• Generator Security Obligation
• All new generators will be required to contribute fast frequency response and

system strength

• Generator Reliability Obligation
• All new intermittent generator will be required to put in place storage and

backup, at a level to be determined by AEMO and AEMC.

• Three Years Notice
• All major generators will be required to give three years notice of closure.

18

• Wind generates around 40% of the time and solar generates 20-30% of the time
• Finkel recommends mandatory storage and backup for new intermittent renewables
• This levels the playing field – renewables now required to pay for intermittency

19

* Illustrative: Storage costs are based on 4 hour storage at 25% capacity.

Range Average

Finkel package - Three year notice period

• The last five closures were Hazelwood, Northern, Anglesea, Redbank and

Energy Brix. They provided an average of five months notice before closing

• Finkel recommends all large generators (coal, gas, wind, solar, hydro) be

required to provide three years notice ahead of closure, which could be written into the National Electricity Rules as part of their licence to operate.

Clean Energy Target - First proposed by John Howard

• Howard Government proposed a Clean Energy Target in the 2007

election campaign:

• required 30,000 GWh each year from low emissions sources by 2020
• low emission sources were technologies emitting less than 200kg CO2e/MWh

i.e. renewables and fossil fuels with carbon capture and storage

• intended to replace existing and proposed state and territory schemes with a

single national scheme

21

Finkel package - Clean Energy Target

• Why Finkel concludes an investment mechanism needed?
• Investment freeze outside of renewables as energy market is operating with a

risk premium for policy uncertainty

• Market needs certainty to invest in fossil fuel generation (existing and new)
• Investment uncertainty is affecting system reliability and security and causing

higher prices

• Current mechanism (RET) is not technology neutral

22

Finkel package - Clean Energy Target

• Generators that produce power below a baseline of CO2-e/MWh

would create a certificate

• Finkel leaves setting the baseline to government
• The size of the certificate would be proportionate to the amount their

emissions are below the baseline

• Retailers would need to buy certificates from generators and the price

would be determined by the market

23

Difference between CET and an EIS

• A CET only has incentives, no penalties on existing coal. No prohibitions or penalties on new coal being built
• Unlike CET, an EIS penalises new and existing coal

24

Clean Energy Target lowers prices
