“We need to be honest”: Building Renewables is Expensive

From Watts Up With That?

Essay by Eric Worrall

Establishment energy players wriggling on the hook of their own flawed green energy narratives.

Your power bills are going up, according to one energy boss. Here’s why

By national regional affairs reporter Jane Norman

You came here for truths and straight talk, so, here’s a doozy.”

Standing on stage at the National Press Club — being beamed live into offices and lounge rooms across the country — one of Australia’s top energy bosses was preparing to say what few in the industry will acknowledge publicly.

Jeff Dimery — CEO of Alinta Energy — looked up from his notes on the lectern and delivered the promised doozy to the audience.

“Australians will have to pay more for energy in future,” he says.

We need to be honest about that.

Yes, renewables are the “lowest cost, new form of generation”.

But building the wind and solar farms at the scale required to replace coal, together with the batteries needed to store the power, and the new network of transmission lines to distribute that power to consumers will involve tens of billions of dollars’ worth of investment.

The Australian Energy Market Operator’s own figures suggest the transition will cost around $383 billion between now and 2050.

When asked who pays, Dimery replied: “it all comes from consumers, whether through the bill directly or through the tax base.

This is a big change from previous claims that renewables would bring down near term prices.

Electricity prices predicted to fall as renewable supply increases, gas price falls

Posted Mon 21 Dec 2020 at 5:32am

Key points:

  • Electricity prices are expected to fall by 9 per cent over the next three years
  • More renewable energy production is behind the fall
  • Power prices in Canberra are predicted to buck the trend

Household electricity bills are expected to fall by 9 per cent over the next three years as more renewable generation joins the grid.

A new report by the Australian Energy Market Commission (AEMC) predicts all states in the National Electricity Market — NSW, Victoria, Queensland, South Australia and Tasmania — will have lower energy prices in 2023.

The residential electricity price trends report 2020, published by the advisory body today, projects the ACT will have a slight rise in electricity prices over the next three years.

The report says the main reason for the drop is lower gas prices and the introduction of new sources of energy generation like solar and wind.

It also says network costs and environmental costs are falling, too, although they contribute less to the overall reduction.

It is not just the ABC. The AEMO, the industry body tasked with regulating the East Coast Australian energy grid, has also frequently added to the confusion about the true cost of renewables;

Renewables push NEM electricity prices down to historical levels

23/10/2023

AEMO’s latest Quarterly Energy Dynamics report shows that wholesale electricity prices averaged $63 per megawatt hour (MWh) in the September quarter, down 41% from the June quarter ($108/MWh) and 71% ($216/MWh) from Q3 2022.

By region, South Australia recorded the highest average quarterly price at $92/MWh, followed by New South Wales ($81/MWh), Queensland ($65/MWh), Victoria ($49/MWh) and Tasmania ($29/MWh).

Total electricity supply by fuel type saw renewables (wind, grid-scale and rooftop solar, hydro and other sources) contribute 38.9% of total supply, up 4.6%, while black coal’s share fell 3.4%, primarily due to the Liddell Power station closure, and gas fell 2.3%. Brown coal’s market share increased 1%, mainly due to fewer unplanned outages.

AEMO Executive General Manager Reform Delivery, Violette Mouchaileh, said that the growing influence of renewables in the NEM was apparent in the warmer September quarter as prices returned to historical levels.

Record renewable generation output helped push down average wholesale electricity prices by more than two-thirds, double the occurrence of zero or negative wholesale prices (19%) and reduce total emissions by 11% compared to the previous September quarter,” Ms Mouchaileh said.

“Renewables also supplied a record 70% of total energy used over a half-hour period, with rooftop solar contributing 39%, again highlighting the likely benefit from coordinating rooftop solar and home batteries.

There is no excuse for this confusing messaging about prices. Renewables were always going to be expensive. It was up to the industry oversight body to keep people informed. Does leaving out the bit about how much renewables cost seem like a reasonable effort to keep people informed?

According to the AEMO “Who we are” page“… AEMO provides the detailed, independent planning, forecasting and modelling information and advice that drives effective and strategic decision-making, regulatory changes and investment. …”. Do articles like the fluff piece above, which somehow fails to mention that any renewable driven cost reduction is temporary, that someone has to pay for all the green infrastructure, does any of this seem like the AEMO is adequately discharging its duty to provide independent advice?

$383 billion is just under $15,000 for every man, woman and child in Australia, or $39,000 for every working person in Australia, just to pay for initial construction. All those extra transmission lines and renewable systems will have to be maintained, at a cost of billions of dollars every year in addition to the cost of maintaining existing infrastructure.

Australia’s peak demand was 31GW in 2023-24, serviced by a capacity of 55GW. According to Wikipedia, the capital cost of building new coal capacity is US $4,074 / Kw to around $1,201 / Kw for gas.

Isn’t climate change supposed to create superstorms and violent weather? If say a big hail storm comes along and wrecks a vast acreage of solar panelsas happened last year in Nebraska, well that will have to be paid for as well.

What are the alternatives to renewables?

Underinvestment in Australia’s energy infrastructure has left most of it in a decrepit state. Lets assume for a moment we have to replace it all.

55GW x 1000000 (convert to Kw) x $4074 = US $224 billion to completely replace all of Australia’s coal capacity with coal. Multiply by 1.54 to get Australian dollars, and you have $345 billion – well short of the $383 billion Energy CEO Jeff Dimery estimated for renewables. If the coal plants use brown coal, which has zero value except as fuel to be shovelled into an adjacent generator, that is a saving of $38 billion in capital costs, + the system does not incur higher transmission line maintenance charges, and a massive cost every time. We save at least $38 billion, and since coal is dispatchable, we wouldn’t have to panic every time the wind dies.

And of course there is the very real risk the $383 billion costing is a massive underestimate. A lot of rather arbitrary assumptions go into calculating such numbers, such as the battery capacity required to accomodate renewable intermittency. Extreme excursions from normal weather conditions such as season long wind droughts over large geographical regions occur often enough to be a problem.

Even when the power doesn’t completely fail, economically damaging spikes in electricity prices can devastate the finances of energy intensive businesses. No energy intensive business can afford $5000 / MWh on a regular basis.

Hands up who still thinks renewable energy sounds cheap? How many people who voted for this train wreck of a left wing green government fell for their dubious claim that renewables would bring down prices? How many voters knew the true cost of green energy, before they cast their vote?

Green energy is a bottomless money pit, always was, always will be. It is time for politicians to be honest with voters, and put a stop this colossal waste of taxpayer resources, before they burn even more money for no benefit.
