What’s the True Cost of Wind Power?

Newsweek OPINION

By Randy Simmons 4/11/15 at 5:22 PM

As consumers, we pay for electricity twice: once through our monthly electricity bill and a second time through taxes that finance massive subsidies for inefficient wind and other energy producers.

Most cost estimates for wind power disregard the heavy burden of these subsidies on U.S. taxpayers. But if Americans realized the full cost of generating energy from wind power, they would be less willing to foot the bill—because it’s more than most people think.

Over the past 35 years, wind energy—which supplies just 2 percent of U.S. electricity—has received $30 billion in federal subsidies and grants. These subsidies shield people from the uncomfortable truth of just how much wind power actually costs and transfer money from average taxpayers to wealthy wind farm owners, many of which are units of foreign companies.

Proponents tend to claim it costs as little as $59 to generate a megawatt-hour of electricity from wind. In reality, the true price tag is more than two and a half times that.

This represents a waste of resources that could be better spent by taxpayers themselves. Even the supposed environmental gains of relying more on wind power are dubious because of its unreliability—it doesn’t always blow—meaning a stable backup power source must always be online to take over during periods of calm.

But at the same time, the subsidies make the U.S. energy infrastructure more tenuous because the artificially cheap electricity prices push more reliable producers—including those needed as backup—out of the market. As we rely more on wind for our power and its inherent unreliability, the risk of blackouts grows. If that happens, the costs will really soar.

Financial Post, 2015

Parker Gallant, the former banker who several years ago launched FP Comment’s prophetic Ontario’s Power Trip campaign against the province’s expensive and pointless electricity industry reforms, has some new advice for the government. As the price of electricity soars, Ontario industries and consumers are being hammered by rate increases that seem never-ending. In an open letter today to Energy Minister Bob Chiarelli, Mr. Gallant lists a few easy initiatives the government could undertake to stop some of the madness and save consumers billions of dollars.  Terence Corcoran

LETTER FROM PARKER GALLANT

April 1, 2015

The Honourable Bob Chiarelli, Minister of Energy,

Legislative Building, Queen’s Park, Toronto ON, M7A 1A1

Dear Minister Chiarelli:

Re: Dropping Ontario’s Price for Electricity

I have noted the difficulty you have experienced over the past several months trying to convince the media and the general population of Ontario they should simply bite the bullet and accept the fact that electricity prices will continue their above inflation climb. Having studied the situation I believe I have come up with some suggestions that would allow you to move things in the opposite direction.

First I suspect that Premier Wynne and Finance Minister Sousa exerted considerable pressure on you to come up with a scheme to help out the 500,000 to 700,000 “low-income” households in the province experiencing what is generally referred to as “energy poverty.” While the plan recommended came from the Ontario Energy Board and was altered somewhat by yourself I believe I have a better plan.

More on that later in this letter.

I also suspect that the Premier and Finance Minister told you unequivocally the OCEB was finished at the end of the year as they wish to wave better deficit numbers in front of those pesky credit rating agencies. The $1.2 billion that went to keep electricity rates down, a little bit, would no longer be available and they made that clear to you.

While you did your best to dance around the issue associated with the upcoming big jump in our electricity bills I could see the criticism was troublesome for you. As a result I believe my suggestions on what you should do will put some spring back in your step.

Here they are:

Recommendations to reduce future ratepayer bills

Conservation spending for the period 2015 to 2020 is forecast and budgeted at $1,835 million so drop it and that will provide close to $400 million annually that can go to reduce electricity prices.

Next, cancel the acquisition of the 500 MW of renewable wind and solar that you instructed IESO to acquire. That will save an estimated $200 million annually in future costs that would increase our rates.

I note there are 510 MW of wind generation contracts awarded that have not yet obtained their REA from the MoE and I recommend you also cancel those. I estimate that would provide relief from future increases of another $200 million per annum. I would suspect the costs of exiting these will be nominal.

Needless to say the cancellation of the above 1,010 MW of renewable energy will reduce future power surpluses meaning the HOEP might show some upward movement. That would allow all the dispatched wind and solar, spilled hydro, steamed off nuclear and idled gas to be sold via the market place to our neighbours. I estimate we could sell anywhere from 10/15 TWh annually at a price of somewhere around $40 million per TWh which would earn revenue of $400/600 million annually.

I would also cancel the new OESP plan which is estimated to cost $200 million (including a new administrative bureaucracy costing $20 million) annually.

Now if you do the math on the above the amount of money your portfolio would save in the future and also generate new income it totals $1.7 billion.

You could than use some of that $1.7 billion to both decrease electricity prices and provide relief for those suffering from “energy poverty.”

My recommendations on those two issues follow:

Recommendations to relieve “energy poverty”

First you should instruct the OEB that the .12% allocated to the LEAP program be increased immediately (providing you have completed the other recommendations) to 1% which will immediately make over $30 million available to the social agencies for relief purposes. You should also increase the maximums per household to $1,000 and instruct the OEB that the Return on Equity and/or Return on Assets for the LDC are to reflect a reduction to accommodate this.

Second you should drop the TOU off-peak rate from 7.7 cents per kWh to 5 cents per kWh. The cost of this would be about $350 million. It would also benefit many of those “low-income” households meaning they would no longer suffer from “energy poverty.” The other benefit is that the ratio of offpeak to on-peak would be much closer to the 3 : 1 ratio that the Auditor General suggested it should be and get more people to shift their use. It would also benefit our business community.

The cost of the two above recommendations are less than $400 million meaning ratepayers will be better off by avoiding future rate hikes and seeing some relief on existing rates. At the same time the TOU pricing will provide a clear signal that usage should shift preserving the “conservation” theme.

I certainly hope you will give my suggestions some serious thought and I do look forward to your response.

Yours truly,

Parker Gallant

Wind farm areas forced “industrial zones,” says scientist

A “boutique solution to a mega-mall problem”

This is from this week’s edition of Inside Ottawa Valley, in the Kemptville Advance,written by retired scientist David G. Stephenson. Part 2 appears next week.

An excerpt pertaining to wind power generation follows:

Across the province advancing wind turbines are changing the wind swept countryside into a scene from H.G Well’s “War of the Worlds”. Wind power is clean and cost competitive, but the turbines are very large, unsightly, noisy industrial installations. A wind turbine will immediately zone everywhere within eyeshot as industrial, and people prefer not to live or conduct their recreational pursuits in an industrial zone. Consequently large wind farms are now being built over water.

A wind farm filling all of this country’s portion of the great lakes might just, when the wind was blowing, generate enough power to replace our use of fossil fuels.

But the output of wind farms is unpredictable and only available a quarter of the time. Wind power, like geothermal and tidal power is a boutique solution to a Mega-mall sized problem. Their contributions can only be useful supplements to a robust anchoring source of non-polluting energy.

Wind farm “monsters bad for Ontario: Realtors shoot back at property value study

Looks like a great place to live!!
Looks like a great place to live!!

Jennifer Paterson, Canadian Real Estate Wealth, December 18, 2014

A recent study by the University of Guelph, which found wind turbines do not have an impact on nearby property values, might have earned a big sigh of relief from investors – but the study’s results have been strongly criticized by members of the real estate industry.

“I have had several deals fall apart in this area because, in the appraisal report, it has been mentioned that there are windmills visible or adjacent to the property and, once a lender gets wind of that (forgive the pun), they will not fund a mortgage,” said Angela Jenkins, a mortgage agent at Dominion Lending Centres, who lives and works in the Melancthon region, where the study was conducted.

“If a person cannot get financing due to windmills, then how can this be a positive thing?”

The study, which was published this month in the Canadian Journal of Agricultural Economics, analyzed more than 7,000 home and farm sales in the area, and found that at least 1,000 of these were sold more than once, some several times.*

John Leonard Goodwin, who has been a real estate broker for more than 10 years in the Grand Bend, Ont. market, asserted that wind turbines absolutely do affect property values. “Turbines complicate your property enjoyment, period,” he said. “That alone spells depreciated value(s).

“Turbines should be in remote, unpopulated locations. To all the folks who have turbines on their property: Enjoy your $18,000 per turbine per year, because you will be giving most of the lease payments back (in much lower property value) when you sell.

“These monsters are very bad for Ontario,” he continued. “We all pay to subsidize the electricity they produce and they will also cause a significant loss of real estate value.”

Lynn Stein, a sales representative at Hartford and Stein Real Estate, lives and sells real estate in Prince Edward County, where a large-scale wind turbine project is slated to begin.

“The turbines that are proposed here are quite large,” she said. “The majority of the population here very clearly doesn’t want them.

“Put simply, if you were to buy your future home, given the choice, would you buy where you would have noise, shadow flicker, an industrial view, potential health issues caused by the turbines, and the possibility of a very difficult resale, or would you spend your money elsewhere?”

*Wind Concerns Ontario Editor’s note– The writer is incorrect: Vyn had a data set of 5,414 residences but very few, 124, were within 5 km of a turbine. Several were as far as 50 km from a turbine. This is a tactic designed to “dilute” any actual effect. Author Richard Vyn himself said that the limitations of this study (sponsored by MPAC, perhaps to buttress their own disastrous study on this issue earlier this year) were significant and should not be overlooked. Toward the end of his paper he admits, “…while the results indicate a general lack of significantly negative effects across properties examined in this study, this does not preclude any negative effects occurring on individual properties.”

The Realtors and financing professionals contacted for this article also did not note that Vyn failed to include expired listings, i.e., properties that were listed for sale, but never sold.

Turbines near Ridgetown: environmental review tribunals ignore evidence of adverse health effects

Big money on one side, families on the other

Jonathan Sher, London Free Press, November 20, 2014

A judicial fight over the future of wind turbines in Ontario wrapped up Thursday with the fate of the province’s green energy law in the hands of judges.

On one side is big money, wind energy giants like Samsung and a Liberal government intent on becoming a world leader in creating green energy.

On the other are four families in Huron and Bruce counties whose homes are close to dozens of proposed turbines.

But while it seems a David and Goliath affair, the underdogs have enlisted a legal pugilist who Thursday seemed to dance circles around the arguments of his adversaries, wrapping up a four-day hearing in London with an emotionally-loaded challenge to three Superior Court justices.

“The system has utterly broken down,” said Julian Falconer. “You have been tasked with keeping these people safe.”

Falconer was the most dynamic of lawyers representing four families in Southwestern Ontario battling the building of wind farms.

It’s not the first time lawyers have challenged the Green Energy Act in court. Three years ago, wind opponents lost in court fighting a decision by an environmental review tribunal to allow a wind farm. But the 2011 effort had a handicap this one does not — it was a judicial review, in which judges must give deference to the tribunal.

This time, Falconer wants the three-judge panel to:

  • Halt, by issuing what’s called a stay, wind farms that are expected to be tested in January.
  • Rule the environmental tribunal violated the constitutional rights of wind opponents when it refused to allow new evidence from a Health Canada study.
  • Allow wind opponents to stop wind farms by showing they might be seriously harmed rather than proving they had been harmed.

The judges expect to issue a decision on the stay soon, and while they didn’t specify a date, it’s likely they’ll act by January.

Environmental review tribunals shield their eyes to contrary evidence, Falconer said.

“They keep the blinders on. They’re not interested in new information. They’re interested in getting the turbines up,” he said.

But lawyers for the government and wind companies disagreed, one arguing the Health Canada study only showed a link between turbines and annoyance and the early results hadn’t yet been peer-reviewed.

“It’s a work in progress,” said Darryl Cruz, who represents St. Columban Energy.

The decision by the environmental tribunal was correct and wind companies should be allowed to complete their wind farms, he said.

That’s a position one Niagara wind opponent has been fighting for about four years, moving from her Welland home to keep away from planned turbines.

“It’s just wrong,” Catherine Mitchell said.

Wind opponents say turbines cause dizziness, headaches, heart palpitations and other illness.

The government says that’s wrong and that neighbours are protected because turbines are placed at least 550 metres from homes.

Ontario has more than 6,000 wind turbines built, planned or proposed, mostly in the southwest. Turbines account for about 4% of Ontario’s power.

In Queen’s Park this week, MPP Jim Wilson asked the Premier and the Minister of the Environment whether it was true the government was about to approve a wind power project next to the Collingwood airport, despite concerns for aviation safety.

The government side of the Legislature is seen to be laughing at the question, so inappropriately that the Speaker has to admonish them saying, “That’s enough.”

In response, the Environment Minister said, “there are environmental assessments for these things,” and then said that the federal Minister of Transport refuses to return calls from provincial ministers. He concluded by saying that airport safety is a matter of federal jurisdiction and that Ontario is looking to the federal government for leadership.

(He then went on to claim that he flies in and out of the Island Airport in Toronto all the time, which is flanked by office towers, and has no problems.)

Wind farms expensive, unreliable, inefficient: UK science research

Wolfe Island: destruction of a pretty place and for what?

Wolfe Island: destruction of a pretty place and for what?

Donna Rachel Edmunds, Breitbart News, October 27, 2014

Wind power is too variable and too unpredictable to provide a serious alternative to fossil fuels, a new study by the Scientific Alliance and the Adam Smith Institute has confirmed. The researchers concluded that, although it is true that the wind is always blowing somewhere, the base line is only around 2 percent of capacity, assuming a network capacity of 10GW.

The majority of the time, wind will only deliver 8 percent of total capacity in the system, whilst the chances of the wind network running at full capacity is “vanishingly small”. As a consequence, fossil fuel plants capable of delivering the same amount of energy will always be required as backup.

The report was undertaken by the Scientific Alliance and the Adam Smith Institute. Using data on wind speed and direction gathered hourly from 22 sites around the UK over the last nine years, the researchers were able to build a comprehensive picture of how much the wind blows in the UK, where it blows, and how variable it is.

They found that, contrary to popular opinion, variability was a significant factor as “swings of around 10 percent are normal” across the whole system within 30 – 90 minute timeframes. “This observation contradicts the claim that a widespread wind fleet installation will smooth variability,” the authors write.

Likewise, and again contrary to popular assumptions, wind does not follow daily or even seasonal outputs. There were long periods in which the wind was not blowing even in winter, making it difficult to match generation of wind power to demand. The report concludes that covering these low periods would either need 15 storage plants the size of Dinorwig (a pumped storage hydroelectric power station in Wales with a 1.7GW capacity), or preserving and renewing our fossil plants as a reserve.

Most significantly, it found that the system would be only running at 90 percent of capacity or higher for 17 hours a year, and at 80 percent or higher for less than one week a year; conversely, total output was at less than 20 percent of capacity for 20 weeks of the year, and below 10 percent during nine weeks a year. “The most common power output of this 10GW model wind fleet is approximately 800MW. The probability that the wind fleet will produce full output is vanishingly small,” the authors note. The consequence is that many more wind turbines will have to be built than is often assumed, as the capacity of the fleet can’t be assumed to be synonymous with actual output.

The findings will deliver a body blow to governmental claims that their current target of generating 27 percent of energy from renewable sources – mostly wind and solar – by 2030 is credible.

“If there were no arbitrary renewable energy target, governments would be free to focus on what most voters expect: providing a framework in which a secure and affordable energy supply can be delivered,” commented Martin Livermore, director of the Scientific Alliance.

“If emissions are also to be reduced, the most effective measures currently would be a move from coal to gas and a programme of nuclear new build. In the meantime, the renewables industry continues to grow on a diet of subsidies, and we all pick up the tab. Getting out of this hole is not going to be easy, but it’s time the government started the process rather than continuing to dig deeper.”

According to the 2013 Renewable Energy Roadmap (the most recent to date), offshore wind capacity reached 3.5GW by June 2013, and onshore capacity reached 7GW in the same month. Governmental modelling suggests that offshore wind capacity will hit 16GW by 2020, and 39GW by 2030.

In the introduction to the Roadmap, the ministerial team headed by Ed Davey, secretary of state for energy and climate change wrote “The Government’s commitment to cost effective renewable energy as part of a diverse, low-carbon and secure energy mix, is as strong as ever. Alongside gas and low-carbon transport fuels, nuclear power and carbon capture and storage, renewable energy provides energy security, helps us meet our decarbonisation objectives and brings green growth to all parts of the UK.”

Ontario’s expensive electricity week: what could $44M have bought?

What the lost $44 million could have bought: 293 family docs, 580 nurse practitioners

Blowing Ontario’s ratepayer dollars

Money lost in just one week could have paid for 580 nurses

So far this October, Ontario’s electricity sector has been blowing our money away at an awesome pace.

Scott Luft, whom I admire for his ability to assimilate comprehensible data, posted on Tumblr some disturbing information about the first 10 days of electricity production (and curtailed production) in Ontario.  Because the fall means low demand for electricity, our current surplus energy supply (principally, wind, solar and gas) was curtailed to the extent that it cost ratepayers $20 million, while the HOEP (hourly Ontario energy price) generated only $8.2 million.  That $20 million of curtailment cost will find its way to the Global Adjustment (GA) pot and onto ratepayers’ bills.

I took a different route and looked at the cost of Ontario’s exports for the week of October 3rd to October 9th —those numbers are also disturbing.  During those seven days, Ontario exported 399,048 MWh (megawatt hours) which was 15.7% of total Ontario demand.   Wind turbines generated and delivered 184,204 MWh, which was surplus to our needs and probably exported.  The money generated via the HOEP from all of the export sales was $56,300 or 14 cents a MWh.  Wind turbines produced just $15,164 and we sold that production for just 8 cents a MWh.

To put this in perspective, the exported production’s cost all-in (contract value per MWh + regulatory + transmission + debt retirement charge) averaged $110/MWh, according to the latest monthly IESO Market Summary August 2014 report’s findings.  Using $110/MWh the 399,000 MWh exported in those seven days hit Ontario’s ratepayers with about $44 million (less the $56,300) via allocation to the GA—that will show up on the electricity line on our bills.

Wind generation alone at the contracted rate of $135/MWh cost ratepayers $24,900,000 plus another $5 to $6 million for their curtailed production, according to Scott Luft.  That $30 to $31 million plus the cost of steaming off Bruce Nuclear, paying idling gas plants, etc., and the additional cost of solar generation, would confirm the $44 million is a reasonable estimate.

What has Ontario missed out on by having ratepayers subsidizing those exports by $44 million for those seven days?

  •  the annual salary of 293 family physicians, or
  • 580 nurse practitioners, or
  • repairing all the Toronto District School Board’s school roofs, or
  • one and a half days of interest on Ontario’s public debt, or
  •  all of Ontario’s 301 MPP salaries for a full year, or
  • 40 MRI machines, or
  • 100 months of mortgage payments on the empty MaRS Phase 2 building, or
  • increasing funding for autistic children by 30% over current levels.

Just a few examples of how the wasted subsidy money that cost each Ontario ratepayer $10 for just one week could have been used!

Wind’s dirty little secret: fossil fuel back up essential

JOHN MINER | QMI AGENCY

October 13, 2014

LONDON, Ont. — I’m green, you’re not.The battle to be embraced as the best environmental choice for Ontario’s power supply is getting down and dirty.

Fed up with the wind-farm sector enjoying what it considers an undeserved reputation as a pristine energy supplier, Canada’s nuclear industry — it generates the lion’s share of electricity in Ontario — has launched a public relations assault against wind.

Both nuclear and wind are major players in the power mix of Southwestern Ontario, home to one of the world’s largest nuclear plants — Bruce Power, near Kincardine — and many of Ontario’s biggest wind farms.

“Wind power isn’t as clean as its supporters have claimed. It performs unreliably and needs backup from gas, which emits far more greenhouse gas than either wind or nuclear power,” said Dr. John Barrett, president and chief executive of the Canadian Nuclear Association, in an e-mail to QMI Agency.

The Canadian Nuclear Association hired Toronto-based Hatch Ltd., a global consulting and engineering firm, to compare wind farm and nuclear energy.

Hatch reviewed 246 studies, mostly from North America and Europe. Its 91-page report concludes wind energy over the lifetime of an installation produces slightly less greenhouse gas — implicated in climate change — than nuclear and both produce a lot less than gas-fired generating plants.

But Hatch says it’s an entirely different picture when wind energy’s reliance on other generating sources is considered.

The engineering firm calculates wind turbines only generate 20% of their electrical capacity because of down time when no wind blows.

When gas-fired generating stations are added into the equation to pick up the slack, nuclear produces much less greenhouse gases, the Hatch study concludes.

Its analysis is that for every kilowatt-hour of electricity produced, nuclear power emits 18.5 grams of greenhouse gases. Wind backed by natural gas produces more than 20 times more — 385 grams per kilowatt hour.

The nuclear industry attack on wind might not be a welcome message for the Ontario Liberal government that has justified its multibillion-dollar investment in Southwestern Ontario wind farms on the basis it’s providing green energy.

But its a position that resonates with Ontario’s anti-wind farm movement.

“We share their concerns on this issue and have been speaking about this for years. We have taken advice from engineers in the power industry, who say that wind power cannot fulfill any of the environmental benefit promises made for it, because it needs fossil-fuel backup.,” said Jane Wilson, president of Wind Concerns Ontario.

On the other side of the debate, the Canadian Wind Energy Association said it has had an opportunity to review the Hatch study.

It said there’s no surprise that when wind and natural gas generation are paired that the mix creates more greenhouse gases than nuclear. But when wind is paired with other potential electricity suppliers, the results are different.

“Unfortunately, by choosing to focus on only one scenario, the study failed to consider a broad range of equally or more plausible scenarios for the evolution of Canada’s electricity grid,” the Canadian Wind Energy Association said.
WHERE ONTARIO’S POWER COMES FROM

For the year 2013:
Nuclear: 59.2%
Hydro: 23.4%
Gas: 11.1%
Wind: 3.4%
Coal: 2.1%
Other: 0.8%

For one minute in time:
(Oct. 13, 2014, 8 a.m.)
Nuclear: 65.8%
Hydro: 24.6%
Wind: 5.9%
Gas: 2.7%”
