Winter energy bills: Avoid a shock

With colder weather comes an increase in electricity and gas use. The AEC has published analysis of average electricity and gas costs by region using the latest energy consumption data. It shows seasonal breakdowns of energy use for each major network, as well as state by state average gas and electricity costs. It also offers simple tips on how people can save on their bills.

Hydrogen for generation

Hydrogen is currently enjoying extraordinary political and business momentum, with the number of policies, national plans and projects growing. With its lack of carbon emissions, there is momentum for its use in generation - but some challenges still remain.

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.

Coal vs 100% renewables: The wrong debate?

A new report released this week tackles the question of “what next?” following the retirement of the National Electricity Market’s existing coal-fired power stations. And it has a simple message: those arguing for a continuation of coal-fired generation are wrong and those mounting the case for 100 per cent renewables are also wrong.

The retail regulatory framework: Still fit for purpose?

During the height of COVID-19, Australian retailers were concerned that the impacts of government interventions might unintentionally impact the ability of retailers to meet their upstream obligations. The impacts on retailers of providing additional protections – on top of the already notable consumer protections in place - and the longer-term debt implications for customers remained a concern.

A changing of the guard: Gas generation projections

The focus around AEMO’s latest assessment of gas supplies for eastern Australia was on its improved outlook. One change in its expectations for gas demand flows from the potential of gas-fired generation in the National Electricity Market. AEMO expects gas-fired generation demand to become more “peaky” and to switch to peaking in winter instead of summer.

Every step counts: China’s marathon journey to become net-zero

In 1971, when asked to assess the influence of the French Revolution, Chinese Premier Zhou Enlai famously remarked that it is ‘too early to say’. So it is not surprising that after President Xi announced China’s aim to be net-zero by 2060, some commentators framed it as ‘the start of a marathon, not a sprint’. But is this assessment fair?

New US modelling points to solar

New modelling is behind an assessment that finds renewable generation is likely to account for as much as 60 per cent of new capacity in the US grid in coming decades.

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?

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

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.

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.

FMG chases green dream

Disruption is one of the cornerstones of the success of Fortescue Metals Group. FMG’s ability to get things done in the face of seemingly insurmountable barriers can be illustrated no more vividly than when BHP and Rio Tinto sought to prevent the then start up iron ore miner from accessing its rail lines in the Pilbara. FMG built its own and outdid its rivals by extending those lines to Perth. Now FMG wants to apply the same zeal to energy and green steel.

The best little blackout in Texas

They say everything’s bigger in Texas. The major power outages from which it is just emerging, were triggered by a polar vortex and impacted around 4.5 million customers. There's been plenty of finger pointing with intermittent renewables being blamed, questions raised about Texas’s go-it-alone attitude and claims of poor preparations stemming from a deregulated energy market.

Big battery bonanza?

The way 2021 has started, you could be forgiven for thinking it is the year of the big battery.
