New NEM records set

New NEM records set

New records for negative and zero price periods in the NEM continue to be set. AEMO’s most recent Quarterly Energy Dynamics report shows records were set in all regions, with negative and zero prices across the NEM occurring 16 per cent of the time - more than double the previous record set in the last quarter of 2020.

Is it time for a full review of WA’s Reserve Capacity Mechanism?

Is it time for a full review of WA’s Reserve Capacity Mechanism?

Reform has been a constant in WA's Wholesale Electricity Market in recent years. The Energy Transformation Strategy was established in 2019 to ensure power system reliability and security. Fast forward, and the same issues that led to that work have amplified, and we now have Stage 2. We look at what it means for the Reserve Capacity Mechanism and generators in the SWIS.

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.

Increases in negative prices: Is it a positive?

Increases in negative prices: Is it a positive?

If there's one thing the Australian Energy Regulator’s State of the Energy Market report has reminded us, it’s that the National Electricity Market can be a wild ride at times. After the NEM achieved the lowest first quarter for wholesale prices since 2012, the last few months have seen an increase in price volatility.

Is minimum demand causing a major headache?

Is minimum demand causing a major headache?

AEMO’s Wholesale Electricity Market ESOO offers insight into the future of the WEM and its potential challenges. It presents a confident picture of generation meeting demand over the forecast period, while on the flipside it singles out the massive uptake of rooftop solar PV for causing a significant near-term issue.

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.

Queensland blackout: Should we let the market run?

Queensland blackout: Should we let the market run?

Following a fire at Callide C Power station on Tuesday 25 May, a series of events resulted in multiple generators disconnecting and 2,300MW of demand being interrupted. This was the most severe event in the NEM since SA's black system of 2016. Like all serious power system incidents, there was a complex chain of issues that will take some time to unpick.

South Australia: Famine one day, feast the next (but one)

South Australia: Famine one day, feast the next (but one)

South Australia could borrow a slogan from another state based on recent vagaries and challenges thrown up by its energy grid. One day it experienced spot prices exceeding $5000/MWh six times between 6pm and midnight and two days later it was reporting near-record minimum demand, which required the step of curtailing rooftop solar to ensure grid stability.

Will network operator batteries hurt competition?

Will network operator batteries hurt competition?

Australia is grappling with the rapid change in how and when electricity is generated and consumed. In Western Australia, recent changes to the Electricity Networks Access Code allow expansion of the role of the network operator. Oakley Greenwood has considered what the amendments mean for competition in the Wholesale Electricity Market.

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.

Capacity markets: The answer to extreme weather?

Capacity markets: The answer to extreme weather?

The fallout from the Texas blackouts has continued with the question of system reliability front and centre and, along with it, whether a mechanism like a capacity market could have led to a different outcome. We take a look at the US experience along with some of the issues it raises.

Dropping demand and plunging prices: Can you have too much of a good thing?

Dropping demand and plunging prices: Can you have too much of a good thing?

The fourth quarter of 2020 saw the NEM reach lowest average demand since Q4 2001 – with SA and Victoria’s spot prices hitting record lows. Are customers benefiting from the price suppression effects of renewable energy generation? Or is the market telling us a different story?

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.

Getting hydrogen on your own supply

Getting hydrogen on your own supply

If you Google “technology roadmap”, in the ‘People also ask’ section there’s a question, “What is the purpose of a technology roadmap?” That seems a good place to start.

Power station upgrades in the time of COVID-19

Power station upgrades in the time of COVID-19

COVID-19 has thrown up a range of challenges – some well understood, others still emerging. For the energy sector, the safety of its workforce and contractors is paramount, so minimising the risk of COVID-19 spread has been a daily focus since the pandemic began. At the same time, with energy an essential service, the industry has ensured this intense focus on workforce safety has not resulted in interruption to energy supply.
