Electricity Price Increases

Queensland structures aren’t designed for tornadoes, but it is likely that those designed for cyclone regions may better withstand a tornado compared to a standard tower. It is also likely they would fail under extreme tornado events…and most likely have done in the past.

To design, engineer and construct structures to cater to any possible weather event or natural event (e.g. earthquakes, landslides, floods etc) would be cost prohibitive and would be engineering for risks that in most cases may never exist. The network is also designed for n-1 (loss one part of the network) for maintaining supply. The interconnectors may cope with loss of one circuit (n-1) under most conditions, but loss of two circuits (n-2), such as double circuit towers collapsing, under high load conditons these interconnecter weren’t designed for us a different matter.

States networks are becoming more reliant on these interconnectors to maintain supply under more and more operating conditions…which has been accelerated through generation closures…and there has been talk of multiple interstate interconnectors in the future to catch up with the changes in their operation roles…thus allowing higher reliance on interstate exports during normal operating conditions.

Australia has generally been free of major tornado risks. Rare events.

Do we now ask that all HV transmission lines in SE Australia need to be tornado rated! Sooty Morrison has said we need to build resilience and adapt as a response to the changes in the climate. Who will foot the bill?

I consulted another ‘Sooty’.

I’m still waiting for an answer but expect it may make more sense.

Yet more dramas with electricity generation and distribution in SE Australia.

Some intriguing pointers on future electricity prices:

An article claiming that electricity prices will decrease.

Looking at SE Qld and AGL and Origin it may already be on the way down compared to 12 months previous.

As an example:
Origin has reduced the daily supply and metering on its Solar Savers plan from $1.3099 daily to $1.2303. (8c pd rounded reduction). Consumption tariff 11 has dropped from 25.56c to 24.91c per unit. (0.65c or approx 2.5% saving). Solar feedin though has also dropped from 17c to 15c. There are other Origin products with lower daily and consumption/usage tariffs, but only 7c for Solar feedin.

For anyone with Solar plans with AGL the best feed in tariff offers have decreased from 20c to 17c. It’s a bit of a mix and match regardless of which retailer you go to. If you are a large net exporter the best retailer and plan offer is likely the one with the highest feedin tariff.

It would be great to pull all the alternate offers apart simply and conveniently. I’ve tried and just noted:
The Federal Govt Aust Energy Regulator - EnergyMadeEasy web calculator is next to useless as it does not factor in solar feedin credits.


Not here in the Deep North where consumers are stuck with Ergon’s monopoly rip-off rates.

Tarrif 11. 26.027 cents/kwh. FIT 0.7842 cents/kwh

We both know I’ve lived in the deep north too!

The catch here is between social equity where electricity is supplied at the same price whereever you live in Australia,
The user pays, which in a commercially driven market allows users in the more expensive to supply north to be charged more. Of course establishing the real cost of supply to the far north remains an elusive goal.

We also have national competition policy, imposed by the Federal Govt long ago, with one desire. To dismantle state run enterprise in favour of private ownership. Whether in the end the other stated outcome of lower costs to consumers delivered through privatisation has come about remains highly contentious. Except for those invested in the private ownership?

Observing how the not quite ready for sale NBN project has treated us all equally (NOT) and delivered or not cheaper internet, perhaps the Deep North may be better of as is with Ergon for electricity the time being.

The downward trend in solar feedin tariffs may see all equal in the near future. Although those in the larger markets around Sydney, Melb, Bris may in the future see competition for customers deliver them the best deals.


My calculations for the previous 10 months show that we paid over $250 more than the figures you quoted for SEQ.

And of cousre, Ergon owns the “poles and wires” whereas the SEQ resellers have to pay Energex for them.

As far as the NBN goes, we are receiving a much superior service at a lower cost than we were with ADSL2+, both with Internode.

So if our experience with the NBN is anything to go by, then bring on competition to Ergon tomorrow.

I’d offer up the current offers from AGL and others, all of which beat a origin for Solar. Another 25-50c pd lower costs on average usage with solar. Yes, there is a big gap for electricity charges between the North and South of Qld. State election in Nov if that is likely to make any difference. :thinking:


Actually 31.10.2020.

I won’t hold my breath.


A couple of articles that could readily have gone on the Climate Change thread. There will no doubt be impacts on electricity prices as well, so this is a better place:


Speculation of a more positive kind through increasing demands for charging of EV’s.

In the next few years the prospects of more grid connected storage may be tempered by a lack of return. The following considers the opportunity battery powered vehicles to take up low cost solar PV sourced energy from the grid during the day and feed it back in at peak times helping to flatten the power demand cycle. This could benefit both the transport and electrical power generation sectors for a single investment in more BEV’s.

The one caveat might be at what premium would the power be purchased back from the consumer? It would need to be at a premium to the value lost from the average expired life of the vehicle battery in each transaction. The battery cost estimates from the SolarQuotes website put a Powerwall 2 at 31c per kWh (lifetime cost). Hopefully a BEV battery is less expensive over time!

For a BEV charged from PV at home with an option to sell back from your BEV at night, it might need close to 40c/kWh as a minimum feedin tariff to cover the cost of the loss of battery life? Or you might expect equivalent savings in kind from your retailer. This high tariff may stack up for the retailers/generators against the cost of investing in more peak power capacity and operation on gas? Updated note to clarify intent.

(Tesla claims a minimum 1500 cycles from a Model 3 battery - 52kWh nominal standard battery. This would give approx 75,000KWh before any lifetime degradation losses.) Elon’s boast of a US$5,000-$7,000 for a replacement battery module seem too good to be true. That’s AU$7,500-$10,500. I guess any day soon the Powerwall will get an upgrade to 52kWh and still only cost AU$15,000 fully installed.


The current standard feed in tarrffs are significantly less than that…

State Current Rate Paid*
VIC 9.9 to 29c/kWh (depending on retailer)
SA 11 to 16.3c/kWh (depending on retailer)
ACT 6 to 12c/kWh (depending on retailer)
TAS 8.9c/kWh
NT Same as consumption rate / grid purchase rate
WA Varies*** e.g. 7.1c/kWh (Synergy)
QLD 6 to 12c/kWh (depending on retailer)
NSW 11.9 to 15.0 c/kWh (depending on retailer)


The feed in rates (excluding NT) are based on the energy component and does not include network costs or other charges. The NT system is a new based system were exports are in effect traded against/offset imports.

One of the reasons that state governments dropped the bonus rates to the energy only rates was because those without solar were subsidising through higher energy costs those with solar. The greatest impact being on low income earners and renters, which often can’t afford/absorb increases in essential products and services.

Obviously it is not just the feed-in tariffs, it is the game where high feed-in tariffs most often are associated with much higher, sometimes obscenely higher, charges for what is taken from the grid. Without the two being considered together it is a game rather than meaningful data.


True only for the ‘Everyday Home’ tariff (flat) - on the ‘Switch to Six’ (split) tariff the rate for export is the flat tariff rate, not either of the split rates.

NT hasn’t had prices like that in years?

My understanding is NT has a net feed in tariff - my meter registers only the export not what I use on site? thats how the figures work when I compare the meter readings to my inverter readings. No complaints here though, no power bills and $500 per year in credit :slight_smile:


I wouldn’t pay too much attention to what is on the EM pages these days, as I suspect none of it has been kept up to date for well over a year.


I’m in NSW, and am paid only 10.2c/kWh ( PowerShop )


Apologies, I wasn’t aware that EM is no longer maintained. Solar Quotes has links for quick reference…and may be better one to review…
