Want Rocketing Power Prices? Just Add Intermittent Wind & Solar – South Australia Did

There’s something uncanny about the relationship between rocketing power prices and renewable energy: ask a German, Dane or South Australian.

Despite some recent propaganda efforts suggesting that South Australians are currently enjoying 1970s power prices, Australia’s renewable energy capital still pays the world’s highest power prices – thanks to its ludicrous 50% Renewable Energy Target.

The subsidies for large-scale wind and solar under the Federal government’s Large-Scale RET will total more than $60 billion over the life of that scheme: the Renewable Energy Certificates issued under the LRET have already added more than $15 billion to power bills, so far.

And then there’s the billions in taxpayer’s money ladled out by the Clean Energy Finance Corporation in soft loans to wind and solar power outfits, as well as billion dollar gifts and grants from the ARENA fund, eagerly lapped up by renewables rent seekers.

Australia’s renewable energy debacle has left more than 42,000 families either without power or facing a daily struggle to pay for it: Australia’s Renewables ‘Transition’ Leaves 42,000 Families in Abject Energy Poverty

But, none of the above is common knowledge, thanks to the useful idiots that occupy the mainstream media.

Australia so-called ‘National Broadcaster’, the ABC was hijacked by neo-Marxists in the 1970s. These days it operates as the official propaganda wing for the climate industrial complex – running puff pieces claiming that Australia is well on its way to an all wind and sun powered future. As JoNova details below, for the ABC, when it comes to Australia’s self-inflicted power pricing and supply calamity, it’s a case of never letting the facts get in the way of a ‘good’ story.

New Report: Renewables indirectly make electricity MORE expensive, so ABC tells Australia the opposite

One big government agency quietly admits renewables make electricity more expensive, and another big gov media agency hides it.

The new AMEC report tells us renewables will make electricity prices go down a tiny 2% in the short run but make electricity more expensive in the long run due to forcing out cheap baseload players. What matters most to Australians — that we can expect our electricity costs to be 2% less than “obscene” for the next couple of years, or that the artificial transition we are forcing on the grid will indirectly make electricity more expensive?

Which message does the ABC headline? Say hello to Trivia!

Renewables set to drive down power prices, new AEMC analysis shows
A flood of new renewable energy projects is likely to drive down household electricity bills
, according to new analysis by government policy adviser the Australian Energy Market Commission (AEMC).

On a national basis, household bills are set to fall by 2.1 per cent — but price falls in the eastern states and South Australia are offset by increases in Western Australia, the Northern Territory and the ACT.

We pay the ABC three million dollars a day so they can parrot press releases.

Unpaid bloggers only had to read to paragraph 24 to find the report says that the renewable subsidy may lead to higher wholesale prices (page V, summary, para 24). The qualification “may” applies to the renewable schemes that don’t “incentivize investment in firming technology”.

In other words the “may” might as well be a “must” in Australia. There are no cheap options for “firming technology” that the RET is not actively forcing out of the market.

There’s always a way to blame coal:
The price reductions will go some way to reversing big power bill hikes driven by increased cost and market volatility driven by the retirement of two brown coal power stations — Northern at Port Augusta in SA, and Hazelwood in Victoria’s Latrobe Valley.

AMEC graph, electricity prices, 2018.


Look what happens when renewables increase and coal decreases…

The big picture is all a bit complicated for big-welfare-journalists. See the graph above. The carbon tax increased the price. The closure of coal plants increased the price. Renewables have increased through the whole duration of this graph and so has the price. What will make electricity cheaper … ABC says “renewables”. Sure.

In the long run, renewables increase the cost of electricity three different ways:
Firstly the subsidy itself costs money, secondly it indirectly it drives out reliable, cheap supply, then thirdly, it adds an unreliable supply that makes the other generators on the grid less efficient and higher in cost too:

The direct costs of the large-scale renewable energy target (LRET) are included in the environmental component of the cost stack. However it is important to also recognise the indirect impact of this policy. The LRET provides incentives for increased quantities of renewable generation to enter the market, even when demand is flat or falling. This is because the revenue that these intermittent generators receive from the scheme is additional to that available.

Over time, to the extent to which the LRET contributes to the exit of thermal generation but does not incentivise investment in firming technologies, it may result in a tighter supply-demand balance and lead to higher wholesale prices from the wholesale market and the LGC penalty price is higher than the expected long-run cost of investing in new intermittent generation.

The overall impact of the LRET has therefore been to drive down wholesale prices in the short term but, in the absence of policies and incentives to encourage investment in replacement generation and firming technologies, it contributes to periods of more volatile and potentially higher wholesale prices. (page 44).

The AMEC committee has been saying the same thing about the LRET since 2015. (2.2 p 31 and 2.2.5 p38).

More solar rooftop PV means higher wholesale prices, not lower:
While the ABC tells Australians that renewables make electricity cheaper, the AMEC report makes it clear that more rooftop panels make electricity generation more expensive for the reliable generators on the grid.

In the WEM in Western Australia, wholesale costs are estimated to increase throughout the reporting period. This is due to increasing gas and coal prices. Changes in the residential demand shape related to increased penetration of rooftop PV also contribute to an increase in wholesale costs. See fig 6.1

In the WEM, wholesale costs were estimated based on a Long Run Marginal Costs (LRMC) approach for the electricity system.

The LRMC approach estimated that wholesale costs are expected to increase in the WEM from 2017-18 to 2020-21 due to:

  • a slight increase in peak demand and a change in residential demand shape related to the increased penetration of rooftop PV systems. This reduces the energy demand met per fixed capital cost of generation, such that the long-run marginal costs of generation increase.
  • increasing gas and coal prices.

The direct costs of renewable energy targets
The direct costs of the Renewable Energy Target are between $50 – $250 a year and rising. But the real costs are the indirect costs. The price of wholesale electricity has tripled in the last three years. Bear in mind, these are averaged costs. Those with solar panels have much smaller electricity bills and therefore pay a lot less RET.

AMEC’s tricky message — prices and volatility are going up
But AMEC gets too clever in graphing the effect of renewables. Here they do a graphic that makes it appear the upside and downside of renewables is kind of similar, when we know, and from all around the world that nations with more renewables have a lot more expensive electricity.

Wholesale costs make up 30 – 60% of your electricity bill:

Wholesale market costs account for 33 to 57 per cent of a consumer’s annual bill in 2017-18, depending on the jurisdiction. Decreasing wholesale costs are the primary driver of retail prices and bills in most jurisdictions over the reporting period. The exceptions are Western Australia and the Northern Territory.

Strap yourself in: 9 Gigawatts of unreliable energy is coming to Australia
From the report itself:

Trends in national residential electricity prices and bills

On a national basis, residential electricity prices and bills are expected to decrease in the period from 2017-18 to 2020-21. This trend is primarily driven by wholesale costs reducing in South East Queensland, Victoria, South Australia and Tasmania. The reduction is driven by the estimated entry of 9,732 MW of accredited, committed or expected new generation and battery storage.

… The wholesale cost reductions are larger than the expected slight increase in network costs and higher environmental costs that are driven by increasing costs associated with the Small-scale Renewable Energy Scheme (SRES).

The 9,732 MW of new generation and battery storage that is expected to enter the NEM over the analysis period is comprised of:

• 8,961 MW of new large-scale intermittent generation.
• 566 MW of new thermal generation and upgraded capacity of existing generators
• 205 MW of battery storage, supported by jurisdictional programs.

What about the new solar PV? That’s not counted in the 9GW?

Australia is adding renewables at an astonishing rate:
How about a 350% increase in the growth of renewables in just one year: We added 1,042 MW of renewable generation in 2018 but will put in an amazing 3,663 MW in the 2019 financial year. We added 30 MW of battery storage in the last year then 75MW is coming this financial year. (see 2.2 p8) This reduced the cost of wholesale electricity from bleeding point to “slightly less”. It’s a temporary blip down from a volatile spike. But the long term trend is up, up, up.

Environmental costs are going up primarily due to the Rooftop Solar PV (Called the SRES)
Of all the renewables going onto the grid, the cost burden that is rising the fastest is rooftop solar, not wind or solar thermal even though they are being added at record levels.

Environmental policy costs directly account for 3 to 14 per cent of a representative customer’s annual bill, depending on the jurisdiction in 2017-18. Environmental policy costs are increasing in most jurisdictions over the reporting period, primarily due to the continued growth in solar penetration and the consequent increase in costs for the Small Scale Renewable Energy Scheme (SRES). (Summary, paragraph 14-15)

In Queensland, not only is half the cost of the panel paid through the SRES scheme (which means it comes from other consumers) but the other half of the cost is paid as a no-interest loan from the Queensland government. (Section B4, p68). This plan which will make electricity more expensive is called the Queensland Affordable Energy Plan. Naturally.

As if that wasn’t enough, the Queensland government pays a $50 rebate, and has a Solar Future Program as well:

The aim of the program is to have 1 million rooftops or 3,000 megawatts of solar PV in Queensland by 2020. The program’s initiatives include reforming feed-in tariffs, statutory voltage limits and Solar 150 (large-scale solar investment).

Subsidies pile on subsidies. How many ways can the government help the ailing, uncompetitive, pointless renewables industry?

For Australia: we’ve got two more years of increasing the unreliable, unnecessary, expensive parts of our grid:

Wholesale costs, wholesale price volatility and the wholesale contract market continue to be affected by environmental policy, with increased levels of intermittent generation, incentivised by the large-scale renewable energy target (LRET). As the LRET target for 2020 is expected to be met through the large volume of new renewable investments in the coming years, and the price of large-scale generation certificates (LGC) is expected to fall significantly as a result, the LRET is not expected to drive additional investment in new renewable projects after 2020.

  1. George Mears says:

    In the US, the propaganda starts with the US Energy Information Agency generating false cost projections for nondispatchable new renewable energy sources by using documentable false assumptions that 1) the operational lives of fossil fuel, nuclear, and new renewable energy sources are all 30 years. The recent report on over 3,000 British offshore wind turbines that experienced an average lifespan of less than half that assumption helps spread the huge costs of wind turbines over many more years than their actual usable lives. The EIA also uses false actual electricity generation and capacity factors. Where the turbines only achieve an average of just over 20% of the turbine motor faceplate value, the EIA assumes average 35% values pretending that much more electricity production was achieved. The EIA estimates never include the mandatory fossil or nuclear backup facility costs that will operate both inefficiently (being turned off and on as unreliable wind snd solar availability fluctuates during the day and may not produce any power at all during significant periods of time that fluctuate on both a daily and seasonal basis. Nor do the EIA costs include the added costs of transmission lines which–for both wind turbines and solar farms may be hundreds of miles longer than for fossil fuel plants. Nor do the EIA estimates include the government subsidies and long term energy buyback contracts without which no renewable facilities would ever be economically viable to build in the first place.
