Insider 26: How will the Hazelwood closure impact the NEM?

This edition of IES Insiders investigates the impact of the 1,600 MW Hazelwood Power Station withdrawing from the National Electricity Market (NEM).

Insider 26: How will the Hazelwood closure impact the NEM?

This edition of IES Insiders investigates the impact of the 1,600 MW Hazelwood Power Station withdrawing from the National Electricity Market (NEM). We assessed the market changes in terms of dispatched electricity, greenhouse gas emissions, power flows across interstate transmission lines, and the revenue impacts to each main type of generator. We also examined the changes to regional wholesale spot prices and how this will affect household electricity costs.

Presentation to the EUAA’s South Australian Energy Forum on 19 October

On 19 October 2016 our CEO, Hugh Bannister, presented to the EUAA’s South Australian Energy Forum event in Adelaide with title: What’s Happening with Wholesale Electricity Prices in South Australia?

Presentation to the EUAA’s South Australian Energy Forum on 19 October

Events in recent months in South Australia have focused government and industry attention on how the cost and security of electricity supply are being affected by the push to renewables.

Our CEO, Hugh Bannister, joined with the South Australian Energy Minister and other senior industry people to review these issues during this forum in Adelaide on 19 October.  Hugh’s presentation concluded with some policy options that could improve outcomes in future.  While there are solutions to the problems that have been highlighted in South Australia in recent months, they do require a focused policy response.

Insider 25: Can Energy Storage Provide Dispatchable Renewables?

This edition of Insiders investigates whether it would be economically viable for large lithium-ion batteries to store electricity generated from wind and large PV sources.

Insider 25: Can Energy Storage Provide Dispatchable Renewables?

This edition of Insiders investigates whether it would be economically viable for large lithium-ion batteries to store electricity generated from wind and large PV sources. A number of projects using this type of application are currently proposed in the National Electricity Market (NEM). If they are viable, it will mean that renewable energy can improve market efficiency and the overall reliability of the electricity system.

Presentation to the EUAA Victorian Energy Forum on 24 August

On 24 August our CEO, Hugh Bannister, presented to the EUAA’s Victorian Energy Forum. Using a sequence of NEO charts covering the period of market volatility in South Australia in June and July, 2016, his presentation takes a forensic look at the factors that drove those events.

Presentation to the EUAA Victorian Energy Forum on 24 August

On 24 August our CEO, Hugh Bannister, presented to the EUAA’s Victorian Energy Forum.  Using a sequence of NEO charts covering the period of market volatility in South Australia in June and July, 2016, his presentation takes a forensic look at the factors that drove those events.

Hugh demonstrated the relative importance of a period of high load due to a cold snap, low wind output, gas plant withdrawal from the market and interconnector outage as key factors driving the market volatility.  Overlaying this was tightness in the gas supply and the closure of Northern Power station, although this closure can be attributed more to the rising cost of mining Leigh Creek coal than to the high penetration on wind in South Australia.

Hugh concluded his presentation with some suggestions for policy responses. His presentation along with those of other presenters at the Forum can be found at http://euaa.com.au/victorian-energy-forum-2016

Insider 24: Can the National Electricity Market achieve 50% renewables?

In this edition of IES Insider, we assess how a 50% renewable energy target by 2030 would impact the National Electricity Market (NEM). We carried out wholesale market modelling to project changes to the mix of generation sources and future wholesale prices, as well as the impacts on consumers.

Insider 24: Can the National Electricity Market achieve 50% renewables?

In this edition of IES Insider, we assess how a 50% renewable energy target by 2030 would impact the National Electricity Market (NEM). We carried out wholesale market modelling to project changes to the mix of generation sources and future wholesale prices, as well as the impacts on consumers.

Our modelled target is introduced in 2017 and increases to 50% by 2030. The target applies to all generated energy (including rooftop PV) in the NEM and not separately to each state. While we haven’t modelled the Queensland and Victorian schemes individually, we provide the results of the renewables take up for these regions if a 50% scheme were to be applied across the NEM.

Insider 23: What’s Happening with Wholesale Electricity Prices in South Australia?

Are recent market outcomes in South Australia the result of too much wind power, high gas prices and constraints, an interconnector outage, exercise of market power, inadequacies in the market rules and industry structure, or perhaps some in combination?

Insider 23: What’s Happening with Wholesale Electricity Prices in South Australia?

The press has been running hot in recent weeks about the state of the wholesale electricity market in South Australia.  In this Insider, we examine market data in detail to understand what is happening.  While many commentators argue that too much wind power in South Australia is driving extreme prices, the data points to a more  complex reality.

The article examines possible factors driving prices including wind power and thermal plant retirement, high gas prices and constraints, an interconnector outage, exercise of market power and possible inadequacies in the market rules and industry structure.  Policy prescriptions will depend on the outcome of such analysis.

Insider 22: Re-engineering the NEM within the Half Hour

In this Insider, we look at a current AEMC rule change proposal to introduce optional 5 minute settlement into the NEM.

Insider 22: Re-engineering the NEM within the Half Hour

The AEMC is currently considering a rule change proposal from Sun Metals to introduce optional 5 minute settlement into the NEM.  The aim of the rule change is to remove the distorted incentives in the current half hourly settlements and to give market participants clearer and sharper opportunities to respond to market needs. 

In this Insider, Hugh Bannister reviews the history of the issue and the current proposal from the point of view of how a control system might be designed and implemented.  He specifically addresses some of the concerns that might inhibit the introduction of such a change including its impact on metering, on contracting and on AEMO and participant systems generally. 

The article concludes that the proposal, with some small but significant adjustments, could be implemented relatively easily and quickly.  It also highlights the fact that Frequency Control Ancillary Services (FCAS) could also evolve to  smooth operations within the half hour and within the 5 minutes as fast response technologies such as batteries become more significant.
