In a fluke moment SA and Vic have got cheap electricity (but only thanks to Black coal, and a screwed market)

Yesterdays free advertisement for the Renewables Industry comes from Peter Martin, ANU, and was swallowed whole by The Conversation, and then repeated by The ABC. (If only the ABC had three million dollars a day to spend on checking things before it published them, they might have warned the economist that he doesn’t understand much about the grid or even the energy market.) This kind of anti-coal PsyOps might work on teenagers: Electricity has become a jigsaw. Coal is unable to provide the missing pieces

Yallourn, in the Latrobe Valley, provides up to 20 per cent of Victoria’s power. It has been operating for 47 years. Since late 2017 at least one of its four units has broken down 50 times. Its workforce doubles for three to four months most years to deal with the breakdowns. It pumps out 3 per cent of Australia’s carbon emissions.

And here’s Macarthur Wind Power plant, Victoria’s largest at 420-never-attained-MW. It breaks down nearly every single day:

Texas was prepared for global warming but not the return of the cold

If only climate modelers had warned us that children would know what Frozen Fish Tanks were?

Instead Texas spent most of the last decade and billions of dollars trying to cool the world by changing its electricity grid.

Thanks to market-distorting policies that favor and subsidize wind and solar energy, Texas has added more than 20,000 megawatts (MW) of those intermittent resources since 2015 while barely adding any natural gas and retiring significant coal generation. — Jason Issac

Indeed Texas has the fifth largest windpower fleet in the world — bigger than everyone except China, the USA, Germany and India. But having that industrial fleet of free clean energy didn’t save Texas this week. What happened appears to have been a systemic wide failure on so many levels. But one of those levels surely, is the failure to winterize the grid. There are plenty of gas and wind plants in colder places like Canada and they run through winter just fine.

But the awful truth is, that it costs more to add these “heat and de-icing” features and with everyone planning for Global Warming, well, who needs ’em? It’s almost like ERCOT in Texas assumed the […]

Texas at -20C, five million without power as Wind Turbines freeze

Welcome to Woke World where states pretend to control the weather while the weather controls the state

An Arctic blast; an ice storm called Uri, has frozen up half the wind turbines in the hot southerly Big State of Texas.

Supplier Oncor is warning it may be hours before power is restored. People are livid, their pipes are freezing, some have had no electricity for 12 hours. Their website is down, their phone lines are out. People can’t even report outages.

UPDATE: NY Times is already blaming Climate Change for the frigid weather.

While the wind turbines have been working at only 3 – 10% capacity in Texas. Gas wellheads have frozen so there are gas shortages as well. Details at the end below.

Anchorage, Alaska is warmer than parts of Texas.

Wind Power failure: on average every 3 days, there is a 500MW fail

On average, every 3 days, wind farms generating as much as one coal fired unit, fail on the Australian grid

TonyfromOz exposes a failure rate so common it’s hidden in plain view. Wind “Farm” intermittency is even worse than we thought.

On average, every three days within a one hour period there’s a sudden failure of 500 MW of wind generation — equal to one industrial coal turbine. That’s four full wind farms or about 250 spinning turbines that stopped spinning.

Every time a coal plant trips out, it’s reported as a problem of relying on our “old coal fleet”. But when the same power output fails from wind, it’s the new clean green future at work (!) , and a sign we need to spend another $20 billion to “upgrade the grid” with interconnectors we don’t need, and Hydro schemes we don’t want.

A few wind farms are bad for the grid. More windfarms are worse.

100 times a year we get a 500MW outage

TonyfromOz (Anton Lang) laboriously finds and documents two different kinds of failure. The largest and longest outages are when wind farms are becalmed. But there are many more short sharp and very sudden failures […]

Victoria blows up cheapest electricity generator in the state

In 2017 in its last month of operation, the 53 year old Hazelwood coal plant was still operating reliably 24 hours a day at around $30/MWhr and producing 1360MW of electricity. Despite its age, it could peak at 86% of its original rated output.

After Hazelwood closed, wholesale prices jumped 85% in Victoria. And the annual average spot wholesale price in Victoria in the last year was $100/MWH.

So naturally Victoria wants to build more wind power, and blow up old reliable coal. Every single week in January, when electricity demand peaks in Australia, there were days when one old coal plant could have provided more electricity than all 57 new wind farms on the National Electricity Market could.

How much did it cost to build 57 not-there-when-you-need-it wind farms?

 

The output of all the wind farms in Australia still isn’t enough to reliably produce more than one 50 year old coal plant.

 

In its lifetime Hazelwood made $15 billion dollars worth of electricity (or 520TWH). It paid for itself many times over.

Wind Turbine crashes on carpark in NY

Wind turbines pose a threat not just to bats, birds and bedtime, but also Buicks, buildings and babies.

By some miracle luck, no one was killed. This wind turbine was installed two weeks ago…

Coming soon: insurance premiums to rise in car parks under turbines, and real estate values to fall. Children’s car seats to be reinforced with 6ft thick titanium shells.

Presumably Al Gore and the member for Warringah will dismiss the risk and plan to build one in their own backyards.

Repeat after me: Wind energy is free and there are no hidden costs from installing gigatons of infrastructure across the country to catch low-density random unreliable energy.

Unexpected UK EarthHour at peak time Friday — just after Wind Power hits new high?

Fragile grids

Over a million people customers lost power in the UK yesterday thanks to the sudden outage of a gas and a wind plant. Some of the country’s biggest railway stations were inoperable. Passengers were stuck on trains for up to seven hours. Others stayed in hotels, walked miles or paid “hundreds” for taxis. The outpatient sections of Ipswich Hospital were blacked out for 15 minutes when backup generators failed. “At the height of the Friday rush hour, all trains out of King’s Cross were suspended and remained so for most of the evening.” — BBC. Commuters resorted to using their phones as torches to get out of tunnels in the dark.

Urgent Investigation called for into “fiasco”

According to headlines, at this early stage before the investigation all we know for sure is that wind power is definitely not to blame, but Boris might be. (Seriously, it’s the no-deal Brexit that hasn’t happened).

Officially, people are saying in solemn knowing tones that it is “extremely rare” for two generators to go out at once. But the odd thing about this is how small the loss was. Barfield Gas power is only a 730 MW generator, and Hornsea Wind […]

Finally “world first” study on nine houses shows wind towers make pulsing noise for 3.5 km

Finally, a study looks at data on nine houses within ten kilometers of an old (probably small) wind turbine. What’s amazing about this research is not the result but that this study is so tiny, yet it’s still a “world first”.

There are already probably around 400,000 wind turbines installed around the world.* So you might think that there would have been scores of studies involving hundreds of people and followed up for a year or two. They would have looked at the effect of wind turbines upwind, downwind, side wind, in low wind, high wind, and at different times of day. They’d check for altered sleep patterns, lack of deep sleep, REM sleep, cognitive performance, blood pressure, cortisol levels, and school marks. Dream on. It’s like everything with climate change — who needs data?

Renewables are a $300 billion annual global industry. This work was done with a $1.4 million National Health and Medical Research Council grant. Where is the precautionary principle when we need it?

More renewables, more record prices

Once again, bad luck for renewables. The AEMO put out their report for the first quarter of 2019. Despite a massive growth in renewables, power prices are still not falling as predicted.

The report highlights that record high spot wholesale electricity prices were set in Victoria and South Australia, and nearly in everywhere else as well:

• Victoria and South Australia’s quarterly average spot wholesale electricity prices of $166/MWh and $163/MWh were their highest on record.

• Victoria and New South Wales recorded their highest underlying energy price on record, while Queensland, South Australia and Tasmania recorded their seconded highest energy prices on record.

These record highs were not just billion dollar price spikes, but the actual underlying energy prices as well.

Looks like a trend here:

Warning! Wind power warms local climate for next hundred years, needs 5 – 20 times as much land

It’s not often we see a report that turns things on their head quite like this.

Wind turbines may cause more local warming than global cooling in the next century.

Photo: Jo Nova

If the US were to install a lot of turbines, Wind power could warm the United States by 0.24 degrees Celsius instead of cooling it, because wind turbines “redistribute heat” in the atmosphere. They mix the surface layers. (0.24C would be equivalent to two decades of recent warming.) The largest effect is at night where wind plants can warm the local area by 1.5C.

At least 10 previous studies have now observed local warming caused by US wind farms. Keith and Miller compared their simulated warming to observations and found rough consistency between the data and model.

Nick Carne — Cosmos magazine

The new studies by Keith and Miller were published in Environmental Research Letters and Joule.

Major downer. The power density of wind energy is up to *100 times* less than predicted.

The new research suggests we can’t put too many turbines to close together or the whole group become far less efficient. That means we need 5 – […]
