Greenwashing: Don’t get taken to the cleaners

Greenwashing: Don’t get taken to the cleaners

As the world transitions to a cleaner energy future, many high-profile companies have pledged to reduce their emissions and align themselves with a net-zero future. Making a pledge is not the same as meeting a pledge, and this can give rise to claims of greenwashing. What does the law say about greenwashing? And what does it mean for the energy transition?

Putting some momentum in inertia

Putting some momentum in inertia

The AEC has published a new report by MarketWise Solutions on the introduction of an Inertia Market into the NEM. For some time industry has been aware of the need for a mechanism to recruit inertia to support the NEM as it transitions. We look at what it is, it’s challenges, and four different approaches on how this missing market could be filled.

A minimum requirement: Managing the demand drop

A minimum requirement: Managing the demand drop

The challenge posed by falling minimum demand was again in the spotlight with the release of AEMO's latest supply assessment. The 2021 Electricity Statement of Opportunities highlights the major impact the increasing amount of distributed PV is having on managing the grid.

Paying for Primary Frequency Response: Detailed work underway

Paying for Primary Frequency Response: Detailed work underway

Work is underway to study the pricing of frequency deviation in the NEM and the use of a double-sided causer pays mechanism to manage and encourage Primary Frequency Response services, which are currently mandated from scheduled and semi-scheduled generators and batteries.

Is degasification plausible?

Is degasification plausible?

As energy consumers, we are always looking at more efficient and cost-effective ways of heating and cooling our homes and workplaces. In the southern parts of the country, gas remains a mainstay of heating as many still think it is cheaper than electricity, which is often not the case. But is degasification plausible?

Four pathways to decarbonisation

Four pathways to decarbonisation

The release of the latest UN IPCC report has reignited debate about how quickly Australia should decarbonise and a federal commitment to net zero emissions by 2050. The CSIRO, in conjunction with ClimateWorks Australia, has undertaken an assessment of decarbonisation scenarios for Australia.

Future governance of the NEM: Where to from here?

Future governance of the NEM: Where to from here?

Now that the Energy Security Board has delivered its final advice on the proposed redesign of the National Electricity Market, it's timely to consider what governance structures might be required to support the effective delivery of a Post 2025 NEM. We look at the history and future governance of the NEM.

100% renewable grid: A journey through uncharted territory

100% renewable grid: A journey through uncharted territory

AEMO received headlines with its goal of delivering capability for the grid to manage 100 per cent renewables at any moment by 2025. The announcement was generally well-received but, unfortunately, misreported as targeting the running of the NEM entirely on renewables. Industry participants may ask why AEMO would be indicating a 100 per cent renewables capability by 2025, which is not to say that progress towards a lower emissions market isn’t welcome.

Gas and hydro: Back-up in action

Gas and hydro: Back-up in action

The first quarter of 2021 for the NEM's spot market was notable for its lack of notability. But in a measure of the how the NEM can turn, the Q2 Queensland average price to date is $135.83/MWh, versus $42.64/MWh over Q1. We look at how the market almost always successfully responds to the NEM’s variations, and its reliance on hydro and gas-fired generation to keep the lights on.

Texan energy crisis: Lessons for Australian electricity markets

Texan energy crisis: Lessons for Australian electricity markets

In February Texas endured a winter storm that dragged temperatures well below freezing. Electricity generation plant and gas infrastructure proved unprepared for these temperatures and around a third of the state’s effective capacity went offline for some or all of this period, just as demand was spiking to a new winter record.

Customer benefits don’t necessarily benefit the customer

Customer benefits don’t necessarily benefit the customer

A perennial discussion in energy market policy is the contest between what we are ultimately trying to achieve: “customer benefits” or “market benefits”. When making market rules, or building monopoly assets, rules require that we assess “net market” benefits. A number of recent government policies have been justified on customer benefit assessments alone.

How do we deal with emerging excess supply?

How do we deal with emerging excess supply?

The economics of traditional plants are well understood, but since their construction, the way they need to operate has changed substantially. This has been driven by a combination of the age of the plants as well as the large influx of renewables, which is changing the supply and demand patterns of the grid.

End of era with Yallourn closure

End of era with Yallourn closure

Yallourn has been home to a coal-fired power station for 100 years, but it was recently announced that this would come to an end in 2028 with the closure of the current four unit Yallourn W power station. In providing seven years notice of closure, EnergyAustralia has given the market, policy makers and government time to adjust and avoid shocks. We take a look at the announcement and some history of the power station.

 NEM “fixes” look more like fissures

NEM “fixes” look more like fissures

The National Electricity Market has held up well under the pressure of the COVID-19 pandemic. Workforces and supply have remained safe and retailers have gone to even greater lengths to support customers who are doing it tough.

NSW Generation: What impact intervention?

NSW Generation: What impact intervention?

This week the Federal Government announced it would be prepared to step in to have 1000MW of dispatchable capacity built to replace the retiring 1680MW Liddell power station in NSW if the private sector does not “step up”.

Rewiring the nation or rewinding the nation?

On 8 October the Leader of the Opposition, the Hon Anthony Albanese MP, made his reply to the Federal Budget. In it the ALP proposed a $20 billion policy entitled “Rewiring the Nation”. Is this a good idea? We take a look.

Smoke on the solar: The impact on generation

The extreme weather conditions that led to massive bushfires occurring on both Australia’s south east coast last summer and across California more recently has had a dramatic and far reaching impact on people and communities.
