The nuclear failure

Lawrence Solomon
National Post
December 6, 2003

For four decades, in three provinces, under Liberal, Conservative and NDP governments alike, nuclear power has brought Canadians nothing but grief.

In New Brunswick, nuclear power has all but bankrupted NB Power. The utility now has negative net worth and an insecure supply of power, all because its big gamble in building its one nuclear plant – which accounts for 30% of that small province’s production when operating – didn’t pay off.

In Quebec, nuclear power was less of a disaster, but only because the province recognized its error and pulled the plug early on. One of the two plants built in Quebec was mothballed as soon as it was built; the other produces expensive power. Hydro Quebec remains solvent only because of the huge hydro-electric reserves to which it has access.

In Ontario, nuclear power effectively bankrupted Crown-owned Ontario Hydro in 1997, leading to its breakup and reorganization. Of the 21 nuclear plants built in Ontario, only 14 are operating today. The province’s vast supplies of hydro-electric power from Niagara Falls and other water plants, though they produce inexpensive power, cannot counteract the huge costs the power system must bear from its nuclear system. Even the nuclear plants that do work are financial albatrosses. Darlington, Hydro’s last nuclear plant, came in at $14.4-billion, almost three times its initial estimate and 10 years late. It produces the most expensive power in Canada, raising rates for all and encouraging industries to locate elsewhere. This week’s news, that refurbishing the Pickering reactors is now estimated at $4-billion, or more than five times its initial estimate, is true to form.

Federal taxpayers have likewise been hit: Atomic Energy of Canada Limited, a federal Crown corporation, has bled red ink from the get-go and needs annual transfusions in federal support – the tab to date: more than $20-billion.

Neither are Canadians alone in being disappointed by nuclear power. In the late 1980s, the United Kingdom decided to shut down much of its nuclear fleet, and cancel its nuclear expansion program, when the privatization of its power sector revealed that the country’s Crown-owned utility had been providing parliament with wildly fraudulent financial accounts. The balance of the U.K.’s nuclear fleet, privatized as British Energy in the 1990s, went bankrupt earlier this year, despite generous subsidies designed to keep it afloat.

The story is little different in Germany, Sweden, the United States and every other Western nation, with the possible exception of Finland. Elsewhere, nuclear power remains popular only in nations such as China, Iran, India, Pakistan and North Korea – countries with nuclear weapons programs.

Nuclear power can only survive in a monopoly system, where governments can force society to subsidize its operations. When countries turn to competitive markets to meet their power needs – as has happened in the U.K., New Zealand, and parts of Australia, Canada and the United States – no private sector player has ever built a nuclear power plant.

The U.K. was the first country to turn to competition, at the same time that it privatized its non-nuclear plants in 1989. Almost immediately, the private companies that now had access to the marketplace went on a building spree – the largest the country had ever seen. They soon flooded the U.K. with a vast new supply of inexpensive and clean power, most of it from the modern, high-efficiency natural gas generating plants that the private sector always preferred, but also from some wind power and renewable energy. Rates dropped for residential and small business consumers first, then for big business. The U.K.’s power prices are now a remarkable 30% lower than they were prior to privatization.

In the United States, competition came more slowly, and state by state. Some states, like California, badly botched their attempt at opening up their market, and paid dearly as a result. But most states deregulated sensibly, leading to a flood of inexpensive power in the United States, too. In some U.S. states, power companies have the ability to generate almost twice as much power as they will need on the coldest and hottest days of the year. Since 1999 alone, deregulation has increased the U.S. power supply by 24%, creating an immense surplus. Ontario now depends on this surplus from the United States to get by, and New Brunswick may soon, too.

Ontario, Quebec and New Brunswick are now all reassessing their power systems, wondering whether to pour more good money after bad in an attempt to refurbish their ailing nuclear reactors. If they do, they can count on more of the same – cost overruns, followed by high-priced power if the plants work and no power if the plants don’t.

If they decide to stop their nuclear bailouts, they have a ready alternative in open markets. Small power producers – once they become confident that governments won’t change the rules of the game on them after they had invested millions – will soon flood Canadian power markets with inexpensive and clean power. Power shortages will give way to power surpluses. After four decades of careening from one crisis to another, politicians can move on to other fields.

Execs fired as reactor refit costs soar

Lee Greenberg
CanWest News Service, with files from news services
December 5, 2003

Toronto: Rebuilding four ageing reactors at the Pickering nuclear generating station will cost as much as $3-billion more than originally expected and take five years longer than planned, a report released yesterday states.

“This is an affront to the people of Ontario,” said Dwight Duncan, the provincial energy minister. “It’s a horrible mess.”

He accepted the resignations of three top executives from Ontario Power Generation (OPG), the public utility responsible for the Pickering A restart. The men will collect about $3-million in severance payouts, sources said.

The delays at Pickering left Ontario starved for electricity when consumption peaked, and exacerbated a week-long shortage after the big blackout in August.

Mr. Duncan said it was too early to speculate on the future of nuclear power in Ontario, which supplies about 35% to 40% of the province’s electricity, but industry observers said there is no point in trying to bring the Pickering reactor back on-line.

“The answer now is to terminate the project,” said Tom Adams, executive director of Energy Probe. “We need power plants that work and that cost a reasonable amount of money.”

Without Pickering A’s 2,060 megawatts of power, or about 7% of Ontario’s total capacity, the province has been importing electricity from Quebec and the United States at market rates that have exceeded its own generating costs by 500 times in hours of peak demand.

Premier Dalton McGuinty was quick to blame the previous Conservative government for the cost overruns.

“Not only were the Tories fiscally irresponsible and managerially incompetent, but they failed to exercise their responsibilities,” Mr. McGuinty said yesterday in Charlottetown, where he is meeting with other premiers. “They were negligent when it came to overseeing, on behalf of the people of Ontario, the affairs that were taking place at OPG.”

Mr. McGuinty conceded that purging the top OPG executives will cost millions.

“I don’t think there’s any doubts that there are some people in there with very expensive packages, but the fact of the matter is many have not been doing their job properly. The people of Ontario are paying the price and we’re going to have to move on this.”

The report, authored by former federal energy minister Jake Epp, highlights an “alarming” litany of mismanagement and waste at Pickering.

Mr. Epp blames OPG’s management and board, as well as the company’s sole shareholder – the Ontario government – for failing to take control of the project while costs spiralled.

“There are people in management who accepted sliding deadlines” and other unacceptable excuses, he said. “It is that type of culture, which does not take responsibility and is not accountable, which I believe needs to be changed.”

OPG chairman Bill Farlinger, a key advisor to former premier Mike Harris, and two other long-time Tories – chief executive Ron Osborne and chief operating officer Graham Brown – resigned from the multi-billion-dollar utility yesterday morning.

Mr. Duncan indicated he would have more to say on the Pickering A restart next week. Work on three of the four generators continues at a cost of $25-million a month.

In 1997, four units at Pickering A were taken off-line for safety reasons. Work to get them running again began in 1999.

The Pickering A restart project was originally approved by Ontario Hydro’s board in August, 1999. The estimated cost to refurbish one of the 30-year-old unit’s reactors, Unit 4, was $457-million.

That reactor came back into service on Sept. 23, 2003, more than two years behind schedule and, at $1.25-billion, nearly triple the cost estimates.

Since that time, cost estimates on the project were changed 11 times and completion dates changed 13 times.

Mr. Epp, who served as Conservative MP for the Manitoba riding of Provencher from 1972 to 1993, said bad decisions were endemic to the project.

“What we have concluded was that this project began under a set of flawed assumptions that underestimated the size and complexity of the project from the outset,” Mr. Epp said. “There were people then in charge who believed the restarts would be relatively simple . . . [that] this was a ‘low-hanging fruit.'”

Management deemed it unnecessary to prepare a report on the work and costs involved in refurbishing the nuclear reactor, as is common industry practice.

That lack of structure led to confusion among contractors, who were forced to prioritize projects without any knowledge of overall goals. The result was a “fundamentally flawed” project, the report says.

For example, final engineering packages for Unit 4 – precise instruction booklets given to mechanics and technicians who performed the job – were delivered over 24 months later than originally scheduled.

The construction workforce began to mobilize 18 months before their final work instructions were completed.

“There were often not enough tasks to keep workers fully occupied, and some work had to be redone based on subsequently completed engineering,” the report states. “Of the 43,000 tasks generated for Unit 4, 15,000 were eventually cancelled during replanning.”

A short-sighted decision to keep nuclear fuel in the reactors forced workers to wear cumbersome radiation protection suits, which slowed them considerably.

Workers were operating at about 20% efficiency, Mr. Epp said.

“Even such fundamental things as access to the plant, badges, clearances, authority to enter what area – that’s pretty straightforward stuff. And we found examples of where people stood in line for up to three hours to get into the plant. Then by the time they were suited, by the time they went into an area that was quite congested . . . somebody else from another company was already in the area. So the whole sequencing is put in jeopardy.”

NDP member Marilyn Churley called for a criminal investigation into the project to find out if “something’s gone very, very wrong here,” she said. “I don’t want these three stooges walking away with their big, fat bonuses and leaving a mess for the taxpayers to clean up.

“I want to find out what happened to those billions of dollars and I want to be darn sure that there was no misappropriation of funds.”

Former Tory energy minister John Baird, who commissioned the report, said his government should have kept a closer eye on the project.

“I think the whole issue of oversight could have been stronger, should have been stronger. And I accept that.”

Ontario Energy Board strategy consultation

Energy Probe

December 1, 2003

Submissions from Energy Probe Research Foundation
(Energy Probe)

INTRODUCTION

In Energy Probe’s view, the starting point for consideration of the OEB’s priorities is the mandate of the Board as expressed in the purposes section of the OEB Act. Energy Probe strongly supports the purposes set out in the Act. Balance and fairness are necessities in addressing the public’s interests in regulated energy services.

Energy Probe warns against regulatory hubris

Not all energy problems are best solved through regulation. Regulation is a necessary but limited instrument in dealing with problems in the energy sector. Competitive markets, not regulation, are in the long run more likely to efficiently guide resource allocation and protect consumers. In considering regulatory priorities for the future, the Board should remain mindful of the major lesson of Ontario’s experience with monopoly energy services.

Ontario’s gas sector is a considerable success:

  • Over $7 billion in private capital is currently serving customers of Union and Enbridge, and the structure of the market led to the recent acquisition of Union Gas’ parent corporation for a significant premium over the book value of the assets.
     
  • Far from a burden on taxpayers, these firms actually pay substantial taxes.  
  • Gas issues are rarely a major public concern.
     
  • Distribution rates are reasonable by interjurisdictional comparison.
     
  • The utilities serving customers are reasonably responsive to consumer concerns. Customers are actively represented in regulatory and other fora by a variety of groups who have demonstrable expertise.
     
  • Demand and supply of the commodity are efficiently linked through price. By contrast, Ontario’s electricity sector is a major and growing public policy problem. Political intervention freezing rates and financing capital spending by OPG and Hydro One, has shifted cost from rates to the netherworld of undiscovered taxes. Municipal utilities have been unable to recover transition costs and regulatory assets, leaving many to large balance sheet risks. Some have even suffered negative cash flow. Until recently, there was not even a clear prospect for recovery. Most consumers lack even the most basic information to guide efficient consumption decisions.

    One of the most significant distinguishing features separating the gas and electricity markets is regulation. Ontario’s gas sector is accountable to an independent regulator. Historically, Ontario’s electricity sector was self-regulated. Non-binding public reviews by the OEB of near term rate proposals where introduced in the early 1970s. Consideration of capital spending was declared by all successive Ontario governments from 1974 – 1994 to be beyond the scope of these reviews. It was not until 1992 that Ontario Hydro became subject to directive power from government. Starting in 1998, experiments began with public regulation of electricity monoplies but the independence of that process has been variable.

    Ontario’s lesson is that good regulation can contribute to better governance

    Critics of gas industry regulation sometimes suggest that hearings are too long, there are too many intervenors, and that regulatory costs are unreasonable. The Board itself lists “streamlining the hearing process” as a key project. Energy Probe suggests that the Board should take a wide enough view to appreciate the lesson that good regulation can contribute to better governance. Validation of gas utility rates through public regulation that is based on due process, administered by an independent regulator works well. While the gas regulation can be improved, the model is fundamentally strong and should be preserved.

    The following sections respond to the questions contained in the OEB’s invitation for submissions, published 2003 October 17. In addition, we have provided additional comments on particular areas of concern to Energy Probe.

     

    1. What are the key challenges for the electricity and gas sectors in the short and long term? Ontario’s electricity system is burdened with obsolete, environmentally challenged nuclear, coal, and simple cycle oil/gas-fired generators, many of which are incapable of providing predictable output:

     

  • In the annual period May 2002 until April 2003, these generators supplied 70.7% of the domestically produced power supplied to the IMO’s market. The units providing this output number 37 – 33 of which are passed middle age. Several, like the four Lakeview units, are very close to their point of expiry.
     
  • At least half Ontario’s electricity demand lacks demand-responsive prices due both to administered prices and obsolete metering.
     
  • Taxpayer-backed electricity stranded liabilities are rising.
     
  • Many LDCs are suffering unsustainable financial pressures.
     
  • The power system is vulnerable to acute disruptions, due to potential supply/import shortfalls or transmission problems.
     
  • In addition, all major governmental electricity institutions, both industrial and regulatory face governance challenges. By contrast, Ontario’s gas market is an oasis of efficiency, solvency and customer service. However,

     

  • The market does suffer from some illiquidity.
     
  • Consumers are currently challenged in dealing with volatile and historically high commodity prices.
     
  • Ontario customers are currently burdened by supporting excess transmission capacity into the province.  

    2. What should the OEB do to respond to these challenges?Electricity

    The OEB should encourage LDCs to facilitate customer adoption of interval metering where it is likely to be cost effective in future. There may be efficiencies to be gained through metering and meter data management services being facilitated or managed competitively.

    Energy Probe believes that the 2003 blackout demonstrates the need for utility regulators to pay attention to reliability:

     

  • First Energy, the U.S. utility at the center of the blackout investigation, is regulated by the Ohio Public Utility Commission. Energy Probe notes that the Ohio Public Utility Commission is not mentioned in the interim report of the US-Canada Power System Outage Task Force “Causes of the August 14th Blackout in the United States and Canada”, although, the report does highlight a significant number of First Energy’s deficiencies.
     
  • Energy Probe supports the National Energy Board’s recent initiative to review international transmission system reliability issues. Energy Probe urges other regulators, such as the Ontario Energy Board, to participate actively in grid reliability issues.
     
  • At a minimum, the OEB should require standardized reporting and publication of distribution utility delivery-related reliability and power quality data. Gas

     

  • The OEB should develop gas transmission and storage access rules. Unbundling system contracting for transmission capacity should be considered. Absence of such rules goes some of the way to explaining why gas in Ontario is relatively illiquid.
     
  • The OEB should provide strategic direction encouraging the development of a more competitively oriented storage sector while fairly allocating historic value as appropriate to shareholders and ratepayers.
     
  • The OEB should provide seasonally relevant advice to consumers on gas price trends, bill expectations, and conservation options.
     
  • The OEB might consider inviting the gas utilities to propose a common weather normalization method for forecasting and analytic purposes.  

    3. Are there existing activities in which the OEB is engaged that should be given greater or lesser priority? Implementing Electronic Regulatory Filing appears to have dropped off the OEB’s list of priorities but now should be reattached. ERF would promote public access and should also provide an avenue for efficiency improvements.

     

    4. What new initiatives should the OEB undertake and what priority should they be given? The OEB should work with the IMO to develop a workable program of locational marginal prices (LMP) for electricity that flows through to the retail electricity market. Wholesale LMP was strongly recommended by the Ontario Market Design Committee (Second Interim Report, Recommendation 3 – 4 Nodal Prices). Energy Probe believes that demonstrating progress on LMP would improve the efficiency of Ontario’s overall electricity market and help to restore investment confidence.

    The OEB should consider establishing the capability to undertake economic research on regulatory questions. For example:

     

  • The Board should be analyzing the benefits of separating electricity transmission and distribution.
     
  • There is a prima facie case that Ontario’s rate of efficiency enhancement for household gas usage is less than the rate of efficiency improvements in jurisdictions without utility subsidized conservation programs, not withstanding Ontario’s record of about 10 years of utility subsidized gas DSM. Is OEB-approved gas DSM impairing conservation? There is a widespread belief among some electricity policy professionals in Ontario that reducing the number of LDCs would enhance distribution efficiency. The largest consolidation of LDCs since 1998 was Hydro One’s MEU buying spree – a business strategy that appears to have significantly reduced Hydro One’s financial flexibility and does not appear to have enhanced shareholder value or reduce costs for consumers. Aside from Hydro One, the next largest LDC in Ontario is Toronto Hydro, which has among the highest distribution rates of any large urban utility in Ontario. Neither of these experiences suggests that size is an important determinant of efficiency. What are the factors that drive distribution utility efficiency?

    The Memorandum of Understanding between the OEB chair and the government should be published as it is updated.

    The OEB should not set up an ombudsman office to replace the role of public interest intervenors.

    5. What do you think our first priority should be?

    Energy Probe believes that the Board’s top priority should be to contribute to Ontario’s exit from Bill 210 and the host of problems it has exacerbated or created:

     

  • Developing a workable PBR formula for electric LDCs should be included in the scope of a Bill 210 exit strategy.  
  • Energy Probe suggests that a generic hearing be convened to consider formulaic approaches to LDC ratemaking.  
  • Energy Probe further suggests that, since the benefits associated with Bill 210 were not evenly spread among consumers, that the Board should propose appropriate guidelines to ensure that costs associated with Bill 210 are recovered from the customers associated with those costs, if the government deems it appropriate for Bill 210 related costs to be recovered from electricity consumers. Future of System Gas

    In addition to the questions identified by the Board, Energy Probe suggests that the Board consider providing guidance to the market place on its views about the future of system gas.

    In October, Enbridge circulated a paper among interested parties discussing the future of system gas (“The Need for System Gas” October 2003). The paper observes that system gas is a mechanism for providing valuable load balancing and backstopping services. Energy Probe supports this observation. Energy Probe also believes that system gas can facilitate customer mobility to, from and between marketers. Many customers prefer to use a non-contract service, perhaps because they prefer dealing with a recognized supplier, or because they anticipate that the short commodity market will outperform long markets over the long term, or because they would prefer to address themselves to other matters.

    Energy Probe does not necessarily agree with Enbridge’s assumption that it must continue to take long-term positions in pipeline capacity but that problem is not an immediate concern in any event. Except for potential future issues around pipeline contracting, Energy Probe supports continued utility provision of system gas.

    Energy Probe’s preference is that system gas be priced in a way that is as market-based as possible, with minimum risk to the utility. Energy Probe’s preferred model for system gas is one that is purely spot price pass-through, like the system recommended by the MDC for pricing default electricity service. However, whether system gas is hedged as Ontario’s major gas LDCs currently do, or not hedged as Energy Probe would prefer, system gas provides a valuable service to consumers and should be allowed to continue.

    Promoting Public Participation in OEB Consultations

    Energy Probe suggests that the Board consider developing a funding process to facilitate professional representation for customer groups and public interest intervenors in Board-initiated consultation processes. This will assist the Board in widening the response to its initiatives beyond those stakeholders with a concentrated commercial interest.

    Thank you.

Re: Going nuclear

Tom Adams
Letter to the Editor
November 10, 2003


The Calgary Herald
Re: “Going nuclear,” November 6, 2003, and “Good night’s sleep,” November 12, 2003

The author of your editorial promoting nuclear power for Alberta should have checked the market evidence on nuclear economics before stating that “economics alone suggest that Alberta should not be ruling out the nuclear option.”

In the U.K., nuclear power and natural gas compete directly. British Energy, a privatized nuclear business, was given 15 reactors almost free, enjoyed very good management, and demonstrated significant productivity improvements. All of these advantages were not enough. British Energy is teetering on the edge of complete bankruptcy as the European Union investigates the government subsidies that are now keeping the nuclear plants running. The Bush administration in the US is trying to get billions in subsidies to stimulate new nuclear construction.

Your editorial bases its support for nuclear on studies done by the self-proclaimed “independent” think tank, Canadian Energy Research Institute. CERI’s advocacy of nuclear power is in fact funded by the Canadian Nuclear Association, which in turn gets much of its funding from Atomic Energy of Canada Limited, a federal crown corporation. AECL has already pumped many billions out of federal taxpayers and is using CERI’s “studies” as part of its lobbying campaign for further billions. Nuclear’s failed economics is proven by its reliance on taxpayer dollars.

On Wednesday Nov. 12, you published a letter from Jaro Franta urging people to not “lose any sleep over nuclear waste.” Mr. Franta did not disclose in that letter that he has been a long time employee of AECL, is currently working on a nuclear reactor in Quebec, and has been on the executive of the Canadian Nuclear Society. Stealth commentaries, apparently penned by members of the public but actually authored by paid nuclear industry insiders, is a strategy that industry has long employed in an effort to sway public opinion.

Power supply problems continue

John Spears
Toronto Star
October 31, 2003

Are Ontario consumers ready to pay more for power?

If the August blackout taught Ontarians anything, it’s that the province’s electricity system isn’t as secure as they’d thought.

While a consumer revolt over rising electricity prices stampeded the former Tory government into freezing the energy component of the hydro bill, the blackout showed that having a secure supply is also vital.

A low price is useless if there’s no power in the system.

Perhaps that’s why the freshly minted Liberal government has broken its first promise by telling consumers it won’t keep the price frozen until 2006, as the party’s campaign platform had pledged.

The government is now facing up to the prospect of trying to build a power system that, first of all, has enough juice to keep everyone’s lights on.

At the moment, that’s not the case, and the math doesn’t look good for the future.

On a very hot or very cold day in Ontario, demand for power soars to about 25,000 megawatts – and up to 15 per cent, or close to 4,000 megawatts, has to be imported from our neighbours.

While imports aren’t necessarily evil, the blackout underscored the risk of overdependence.

But if the Liberals keep their promise to shut down every coal-fired generating station in the province by 2007, the supply could get even tighter.

Nanticoke and Lambton, the province’s two biggest coal plants, by themselves can churn out more than 20 per cent of the province’s power on a day of maximum consumption.

Replacing those plants won’t be easy.

The obvious answer: build more generating stations. But there are no simple ways of boosting generating capacity.

The Pickering A nuclear station, with about 2,000 megawatts of capacity, is supposed to be back in service at some point, but its future is uncertain due to mammoth cost overruns and delays.

The Liberals say there’s potential for nearly 4,800 megawatts of new gas-fired plants, but natural gas supplies are tight and natural gas plants may become increasingly expensive to operate.

A new transmission line that would carry 1.25 megawatts of power from Quebec is bogged down on the Quebec side of the border. There’s no certainty it will ever be built.

The province says there’s capacity to construct 6,000 megawatts of wind-powered generators in Ontario, but giant wind farms tend to attract opposition from local communities.

And because the wind blows fitfully, a windmill may deliver power less than 25 per cent of the time.

Conservation is another route to energy security, but the price freeze destroyed any financial incentive for householders and small businesses to cut back.

Lifting the freeze before its scheduled expiry in 2006 sends a better signal to consumers that they’ll have to pay for the privilege of being energy hogs.

The Liberal pledge to keep the freeze in place until 2006 is “one of the promises they never should have made in the first place,” said Tom Adams, executive director of Energy Probe.

“From a conservation and energy reliability point of view, the best thing to do is simply go back to the market price right away.”

Ending the freeze sends the right signal to potential private sector investors, says Julie Girvan, an independent consultant who often works for the Consumers Association of Canada.

“We need to stimulate in the power sector in Ontario,” she said.

“Removing the price freeze, or at least increasing the price, will hopefully do something to stimulate new power development.”

Liquefied natural gas (LNG) risks

Tom Adams

October 24, 2003

Liquefied natural gas (LNG) is rapidly gaining in policy popularity and commercial interest in North America. Energy Probe believes that the potential for catastrophic explosions and the substantial financial risks associated with LNG need to be fully considered before making any decisions to expand our dependence on LNG.

Marine LNG off-loading terminals are proposed for sites near Saint John, New Brunswick and the Strait of Canso, Nova Scotia. Ontario has a small LNG facility, owned and operated by Union Gas east of Sudbury near the town of Hagar. (Almost all natural gas storage in Ontario uses underground storage in sealed natural cavities, a technology that has proven to be extremely safe.)

LNG and other liquefied flammable agents that are gaseous at normal atmospheric pressures and temperatures, such as propane, liquefied petroleum gas (LPG), and hydrogen, are capable of what are known as Boiling Liquid Expanding Vapor Explosions (BLEVEs).

An LNG release on water is particularly dangerous. If LNG contacts water, the LNG boils rapidly, sometimes called rapid phase transition (RPT). The result is that natural gas is released. The resulting gas expansion powers the dispersion of a “cloud” of liquid and gaseous natural gas. This cloud achieves a “super-fluid” effect similar to pyroclastic flows seen in some volcanic eruptions, where the rapid motion of the cloud is powered by the expansion of bubbles within it. Flammable vapor clouds can form if a spill does not ignite immediately.

LNG explosions have been relatively infrequent in Canada and the United States. In 1944, an LNG tank in Cleveland, Ohio exploded killing 135 people. In 1979, the failure of an electrical seal on an LNG pump permitted natural gas (not LNG) to enter an enclosed building. A spark of indeterminate origin caused the building to explode. As a result of this incident, the electrical code has been revised for the design of electrical seals used with all flammable fluids under pressure.

Japan relies heavily on LNG and has so far demonstrated a good safety record.

LNG spilled on or within the hull of a ship can cause brittle fracture of some common types of steel. There have been marine accidents where hull damage due to brittle fractures was incurred after LNG was spilled. Fortunately, LNG explosions did not occur in these instances.

Many proposed LNG terminals have been turned down over the years for reasons that often involve the combined effects of high cost and high risk. Examples include an LNG terminal on the Thames River in London, three LNG terminals that were proposed for California in the 1970s but cancelled, and a land-based LNG storage facility once proposed for Eastern Ontario by the former Consumers Gas Company (now Enbridge Gas Distribution).

LNG is usually thought to be cost effective only where natural gas prices average more than US$3.50 to US$4.00 per thousand cubic feet. Measured at the producer level, North American prices have only exceeded this level for two sustained periods over the last 20 years; however both periods of high prices occurred since June 2000.

Nuclear power can only survive with state aid

Tom Adams
National Post
October 17, 2003

Tom Adams’ response to “Think tank predicts need for nuclear plants necessary to meet growing demand,” published by The Globe and Mail, October 17, 2003. The Globe and Mail article discussed a study conducted by the Canadian Energy Research Institute posted on the Canadian Nuclear Association’s Web site at: www.cna.ca/english/files/study/CNAStudySept16-03.pdf

Letter to the Editor
The Globe and Mail
(This response has not yet been published)

The Canadian nuclear industry’s latest lobby effort to secure government subsidies has arrived in the form of a report purporting to examine “the key economic dimensions of the nuclear industry.”

Like previous nuclear lobbying studies, the new study confuses costs with benefits. For example, nuclear power’s labour intensiveness relative to power sources like natural gas-fired generators, is reported as a benefit. The study ignores the most important issues in nuclear economics – investment risk, government handouts, cost overruns, production declines, and the perverse incentives flowing from federal legislation limiting nuclear liability in the event of accidents.

Reducing subsidies reveals that the costs of nuclear power outweigh its benefits. The clearest case is in the UK where power privatization and competition have revealed nuclear power to be a money pit. The private nuclear company, British Energy, cherry picked the best 15 reactors from a fleet of over 30 and paid only half the cost of construction of the 15th reactor. The government also extended to British Energy its legal shield protecting government nuclear operations from liability in the event of accidents. Despite these advantages, British Energy still failed to pay its bills and is now being renationalized.

As The Times of London noted earlier this month, nuclear power can only survive with “state aid – on a grand scale”.

British Energy’s restructuring deal

Tom Adams

October 14, 2003

Under the deal, taxpayers take on responsibility for the company’s decommissioning liabilities. According to one report, this avoids the UK government from having to include the nuclear stockpile of debt in the public finances, an amount that might sum to £4 billion (British Energy nuclear stations could go for £1 each, By Michael Harrison, The Independent). (Government keeps its options open as nuclear is kept private By Jeremy Warner) A report in the Times (Business Editor’s Commentary: State aid — on a grand scale, By Patience Wheatcroft) suggests that the government’s reporting treatment for the liabilities it has acquired have not yet been determined.

The structure of the state aid is, in part, that taxpayers will be faced with a bill of up to £200 million a year for a decade, and then an unspecified amount after that. Lossmaking, state-owned British Nuclear Fuels will accept a lower price for reprocessing fuel for BE. In addition, the government has also agreed to take over BE¹s multi-billion pound clean-up liabilities – another hit to the taxpayer. (Scrutineer: Light at the end of the tunnel for BE – if Brussels agrees by Martin Flanagan, City Editor) In return, the government requires BE to surrender 65 per cent of its annual post-tax cash flow to the government’s new Nuclear Liabilities Fund. (Financial Times, LEADER: Tough bargaining on British Energy)

After the deal was announced, British Energy’s bombed-out shares, once on the FTSE 100 index of the UK¹s biggest companies, edged up slightly to close at 5.38p last night, having closed on Tuesday at 5.35p. That puts a £33 million value on the company, which was worth £5 billion at its peak. (British Energy debt swap leaves shareholders fuming By Angela Jameson, Industrial Correspondent)

The Times points to the British Government’s muted response to the French state rescue of Alsthom and suggested that British Energy provides the explanation. The Times called the BE rescue deal “semi-renationalisation” and points out that the company suffer another operating loss, this time of £40 million in the five months to the end of August. (Business Editor’s Commentary: State aid — on a grand scale, By Patience Wheatcroft)

The European Commission launched an investigation into the Government’s aid to the company, which it believes could contravene state-aid regulations. The investigation, which started after British Energy received a £650m state loan last autumn, is due to be completed next summer. If it judges that British Energy was being unfairly supported, the company could yet be re-nationalised. The Government repealed the 1989 Electricity Act earlier this year in case it has to re-nationalise the company. (* Daily Telegraph * “DEAL KEEPS LIGHTS ON AT BRITISH ENERGY” by Edmund Conway)

Under the deal, the government also has the right buy any of BE¹s power stations for £1 if the company decides to begin decommissioning work before previously agreed dates. (British Energy still on uncertain ground, by Iain Dey, Deputy Business Editor)

In commenting on the bailout, groups as disparate as Friends of the Earth and the Financial Times called for the end of spent fuel reprocessing. The Financial Times noted, “(The BE saga) has raised the question of whether the storing of spent fuel at reactor sites rather than expensively reprocessing it might not make cost as well as environmental sense.” (Financial Times LEADER: Tough bargaining on British Energy)

Safety deficiencies caused reactor shutdown

Tom Adams

October 7, 2003

Ms. Wells,

I enjoyed your analysis of some of Ontario’s problems with its aging nuclear reactor fleet (Toronto Star, Nuclear Fallout, September 27, 2003).

One note about Pickering A (PA) that I believe is significant but has received virtually no recognition on the record relates to the reasons for PA’s closure in 1997. From a time that dates back to before the original in-service of the station in the early 1970s, the federal nuclear safety regulator had been aware of deficiencies in the design of the fast shut down safety system used in each of the four reactors. After dithering for decades over what to do about the deficiency, the regulator in the early 1990s imposed a license condition on Ontario Hydro related to PA. The regulator ordered that if the safety systems were not upgraded by the end of 1997 following specific design guidelines, the station would not be allowed to operate. Through the mid 1990s, Ontario Hydro failed to make the necessary upgrades. By August of 1997, it was obvious that the upgrades to all units except unit 4 units 1, 2, and 3 could not be completed in time. The safety deficiencies of the PA station were what directly caused the closure in December 1997.

The official version of Pickering A’s “layup” from the nuclear industry always claims that safety had nothing to do with the closure. Your report claims that “the predominate issue was not safety.” In fact, the IIPA report that triggered the 7-reactor shutdown shows repeated explicit references to revelations that (e.g.) “safety margins were compromised” in Ontario Hydro’s reactors. Ontario Hydro’s failure to upgrade the shutdown systems as required in the license was on top of these other problems. The actual history of the Pickering A station proves that safety deficiencies were the real drive

Leave energy waste in the dust

Ellen Roseman
Toronto Star
October 5, 2003

You did your best to conserve energy after the big blackout in August. But now the power is flowing again, you’re running your appliances at full speed.

Maybe it’s time to flip the switch back to energy conservation mode.

“Don’t assume your future bills will look anything like the present ones,” says Tom Adams, executive director of Energy Probe, a Toronto-based consumer group. “You should be thinking about how to save electricity in the future.”

We have a new Liberal government in Ontario, which needs money to fulfil its campaign promises and may scrap the cap on electricity before 2006. Freezing the price at 4.3 cents a kilowatt hour, when the average was closer to 5.9 cents, has already cost the provincial treasury about $1 billion.

And we’re going into a winter when natural gas for heating has risen substantially. Homeowners who signed fixed-price contracts at 10 to 15 cents a cubic metre are renewing them today at 29 to 32 cents.

Retrofitting your home for energy efficiency costs money and the payback doesn’t arrive for many years. That’s why homeowners wait for government incentives before going ahead.

But you can save energy without spending money on a new furnace, front-loading washing machine or double-paned windows.

The secret is to pay attention to dust buildup in three crucial areas of your home, says Adams (also known as Mr. Dusty).

1) The refrigerator. Pull it out from the wall – make sure to disconnect it first – and use your vacuum cleaner to remove the dust that has collected on the coils.

These coils get rid of the heat that has accumulated in the refrigerator. The heat acts as a magnet that attracts kitchen dust and grime, making the whole system work less efficiently.

“You want your attic insulated, not the coils on the back of your fridge,” says Adams.

To make the job easier, you can buy special appliance casters if your refrigerator doesn’t have wheels.

The refrigerator is the biggest energy user of all the appliances in your home, surpassed only by the furnace and hot water heater.

2) The furnace air filter. It should be cleaned or replaced every month to six weeks, especially if you have central air conditioning running all summer or pets that shed hair.

Dust collects here too and makes the furnace run less efficiently. Turn off the power to the furnace first before checking the filter.

“This is a safety issue,” says Adams. “You don’t want your heat exchanger heating up too much because of the fire hazard.”

3) The clothes dryer. You may be conscientious about cleaning the lint filter inside the machine before every load. But that’s not enough.

Check the connector, a rigid or flexible plastic pipe between the dryer and the outside vent. Take it apart and clean it periodically, Adams advises, or replace it if necessary.

Again, it’s a safety issue. Fires can flare in the dryer vent if the pipe isn’t cleaned often, particularly if you’re using a natural gas-powered machine.

Another area where big savings are possible is your water heater, which consumes about 20 per cent of your home’s energy costs. Check the thermostat setting, which most people keep at 160 degrees Fahrenheit.

You can turn down the temperature and still get hot showers and clean dishes. A lower temperature also poses less of a scalding hazard to young children or elderly residents, who can’t get away in time if the water is too hot.

Turn down the thermostat to 130 degrees, Adams suggests, or 140 degrees if your household uses lots of hot water.

Also, lower the temperature on the water heater when you go away for a weekend or longer vacation. This should be as automatic as locking the doors and turning down the themostat for your space heating.

You can insulate the pipes coming out of the water heater, at least the first couple of feet that are easily accessible. Hardware stores sell tubes that fit easily over the pipes.

Here are a few other tips on saving energy when operating appliances from Natural Resources Canada’s office of energy efficiency:

  • Turn off the dishwasher during the dry cycle. Air drying works just as well. 
  • Preheating your oven isn’t required unless you’re baking. Don’t preheat for more than 10 minutes. Also, turn off the oven before the food is completely cooked and let the built-up heat finish the job. 
  • Wash and rinse your clothes in cold water. Modern detergents will get them just as clean as if you’d used hot water. The next person using the shower will thank you, because one or two loads using a hot water wash and warm water rinse will come close to draining the hot water tank.Regular maintenance helps keep your heating appliances at peak efficiency. You can locate a contractor who’s a member of the Heating, Refrigeration and Air Conditioning Contractors of Canada by calling toll-free at 1-877-411-4722, seven days a week, 24 hours a day. (It pays to keep this number handy if there’s an emergency and you need something fixed in the middle of the night.)

    Next week, we look at how to choose an Internet service provider. This will be the last column in a series on cutting household costs that began last May. On Oct. 19, we launch a new series on student finances aimed both at post-secondary students and their parents.
