Jean Charest inaugurated Hydro-Québec's newest generating station, the $1.5-billion Péribonka IV project in the Saguenay, with the same boast Quebec premiers have been using on their subjects for nearly half a century.

"When we speak of energy, we speak of ourselves. We speak of our ancestors. It's part of our DNA, of who we are politically," Mr. Charest said at the 385-megawatt station's opening in December.

It's true that hydroelectricity has been the uninterrupted current of Quebec politics since the Quiet Revolution. But that doesn't mean it's always been the matter of manifest destiny Mr. Charest would like us to think it is.

How else could Hydro-Québec find itself on the hook for about $150-million to Calgary-based TransCanada Corp. without a kilowatt to show for it? That is how much the massive publicly owned utility will pay TransCanada this year to mothball its spanking new co-generation power plant at Bécancour, Que., near Trois-Rivières.

Was it a simple, but embarrassing, forecasting error on Hydro-Québec's part that led it to inaccurately project supply and demand in 2008 and beyond?

Or is the TransCanada payout another example of the cost to taxpayers of the empire-building mentality that the utility has harboured since the province nationalized its hydro assets in 1962?

Transparency has never been Hydro-Québec's strong suit. So, trying to figure out the internal politics at the utility, which generates enough juice to power almost two Ontarios, is an energy-intensive endeavour.

In the fall of 2003, the utility unveiled a five-year plan that sent shivers through Quebeckers, who had long taken their province's electricity self-sufficiency for granted. Hydro-Québec warned of looming shortages unless the new power plants were green-lighted pronto.

It was in that context that Mr. Charest's government approved Hydro-Québec's construction of its own 900-MW gas-fired station west of Montreal, in a region known as Suroît, in addition to a proposal by TransCanada to build a $500-million, 500-MW co-generation facility at Bécancour.

Within months of that, the Charest government unveiled Quebec's most ambitious energy development agenda in a generation - all of which was music to the ears of the empire builders at Hydro-Québec. Under the Charest government's plan, about 9,000 MW in new hydroelectric and wind power capacity will come on stream by 2015.

The fiasco at Bécancour should lead any thinking person to question the wisdom of that plan.

More history: The Suroît station was never built. It became the focus of massive protest by environmental groups, rightly concerned that it would mar Quebec's image as a leader in clean energy. But the TransCanada project went up without as much as a peep from the protesters - or more precisely, the kind of peep that gets media attention.

The bright side is that no climate-warming vapours from Bécancour have been entering the atmosphere since January 1. TransCanada has agreed to shut down the station - which has been open barely a year - for all of 2008, and possibly longer.

In 2003, Hydro-Québec signed a 20-year contract to purchase the electricity produced at Bécancour at a rate tied to the price of natural gas. If it was a dubious deal for Quebec taxpayers then, it's a literally lousy one now.

Warmer winters, the recent closing of Norsk Hydro's magnesium refinery, and the slated shutdown of Abitibi-Bowater's Belgo paper mill are just a few developments that have left Hydro-Québec sitting on huge surpluses of power at least until 2010.

Not long ago, Hydro-Québec would have touted this as a boon to the bottom line. Surpluses could be exported to energy-starved utilities in Ontario or nearby U.S. states at prices higher than those charged to industrial consumers in Quebec.

Now, though, Hydro-Québec frets that if it were forced to buy power it no longer needs from TransCanada, it would have to sell it at below-cost rates on the North American spot market. It's cheaper to pay TransCanada to shut down Bécancour. The Alberta-based producer will get $54-million this year from Hydro-Québec not to produce any electricity, and another fixed fee of about $95-million that it must pay TransCanada whether Bécancour generates electricity or not.

So, if not hype, what are we to make of Hydro-Québec's plans? Not a single long-term export contract with Ontario or any U.S. state has been signed in years, raising doubts about whether any of the 9,000 MW worth of projects in the pipeline are needed or cost effective - especially if Hydro-Québec's talk of promoting conservation is at all serious.

Quebec's capacity to export power to Ontario will double by 2010, to about 2,500 MW, but the Ontario Power Authority's recent proposal for long-term development makes only passing reference to imports. Ontario is aiming to meet its requirements internally.

As usual, the big winners in all of this will be Quebec's aluminum smelters. With Hydro-Québec's big surpluses, their bargaining power to procure yet more cheap electricity has been re-energized. What a waste.

National Grid and SSE to use electrical transformers to heat homes

Grid Transformer Waste Heat Recovery turns substations into neighborhood boilers, supplying district heating via heat networks, helping National Grid and SSE cut emissions, boost energy efficiency, and advance low carbon, net zero decarbonization.

 

Key Points

Grid Transformer Waste Heat Recovery captures substation heat for district heating, cutting emissions and gas use.

✅ Captures waste heat from National Grid transformers

✅ Feeds SSE district heat networks for nearby homes

✅ Cuts carbon, improves efficiency, aligns with net zero

 

Thousands of homes could soon be warmed by the heat from giant electricity grid transformers for the first time as part of new plans to harness “waste heat” and cut carbon emissions from home heating.

Trials are due to begin on how to capture the heat generated by transmission network transformers, owned by National Grid, to provide home heating for households connected to district heating networks operated by SSE.

Currently, hot air is vented from the giant substations to help cool the transformers that help to control the electricity running through National Grid’s high-voltage transmission lines.

However, if the trial succeeds, about 1,300 National Grid substations could soon act as neighbourhood “boilers”, piping water heated by the substations into nearby heating networks, and on into the thousands of homes that use SSE’s services.

“Electric power transformers generate huge amounts of heat as a byproduct when electricity flows through them. At the moment, this heat is just vented directly into the atmosphere and wasted,” said Nathan Sanders, the managing director of SSE Energy Solutions.

“This groundbreaking project aims to capture that waste heat and effectively turn transformers into community ‘boilers’ that serve local heat networks with a low- or even zero-carbon alternative to fossil-fuel-powered heat sources such as gas boilers, a shift akin to a gas-for-electricity swap in heating markets,” Sanders added.

Alexander Yanushkevich, National Grid’s innovation manager, said the scheme was “essential to achieve net zero” and a “great example of how, taking a whole-system approach, including power-to-gas in Europe precedents, the UK can lead the way in helping accelerate decarbonisation”.

The energy companies believe the scheme could initially reduce heat network carbon emissions by more than 40% compared with fossil gas systems. Once the UK’s electricity system is zero carbon, and with recent milestones where wind was the main source of UK electricity on the grid, the heating solution could play a big role in helping the UK meet its climate targets.

The first trials have begun at National Grid’s specially designed testing site at Deeside in Wales to establish how the waste heat could be used in district heating networks. Once complete, the intellectual property will be shared with smaller regional electricity network owners, which may choose to roll out schemes in their areas.

Tim O’Reilly, the head of strategy at National Grid, said: “We have 1,300 transmission transformers, but there’s no reason why you couldn’t apply this technology to smaller electricity network transformers, too, echoing moves to use more electricity for heat in colder regions.”

Once the trials are complete, National Grid and SSE will have a better idea of how many homes could be warmed using the heat generated by electricity network substations, O’Reilly said, and how the heat can be used in ways that complement virtual power plants for grid resilience.

“The heavier the [electricity] load, which typically reaches a peak at around teatime, the more heat energy the transformer will be able to produce, aligning with times when wind leads the power mix nationally. So it fits quite nicely to when people require heat in the evenings,” he added.

Other projects designed to capture waste heat to use in district heating schemes include trapping the heat generated on the Northern line of London’s tube network to warm homes in Islington, and harnessing the geothermal heat from disused mines for district heating networks in Durham.

Only between 2% and 3% of the UK is connected to a district heating network, but more networks are expected to emerge in the years ahead as the UK tries to reduce the carbon emissions from homes, alongside its nuclear power plans in the wider energy strategy.

Climate change poses high credit risks for nuclear power plants: Moody's

Nuclear Plant Climate Risks span flood risk, heat stress, and water scarcity, threatening operations, safety systems, and steam generation; resilience depends on mitigation investments, cooling-water management, and adaptive maintenance strategies.

 

Key Points

Climate-driven threats to nuclear plants: floods, heat, and water stress requiring resilience and mitigation.

✅ Flooding threats to safety and cooling systems

✅ Heat stress reduces thermal efficiency and output

✅ Water scarcity risks limit cooling capacity

 

 

Climate change can affect every aspect of nuclear plant operations like fuel handling, power and steam generation and the need for resilient power systems planning, maintenance, safety systems and waste processing, the credit rating agency said.

However, the ultimate credit impact will depend upon the ability of plant operators to invest in carbon-free electricity and other mitigating measures to manage these risks, it added.
Close proximity to large water bodies increase the risk of damage to plant equipment that helps ensure safe operation, the agency said in a note.

Moody’s noted that about 37 gigawatts (GW) of U.S. nuclear capacity is expected to have elevated exposure to flood risk and 48 GW elevated exposure to combined rising heat, extreme heat costs and water stress caused by climate change.

Parts of the Midwest and southern Florida face the highest levels of heat stress, while the Rocky Mountain region and California face the greatest reduction in the availability of future water supply, illustrating the need for adapting power generation to drought strategies, it said.

Nuclear plants seeking to extend their operations by 20, or even 40 years, beyond their existing 40-year licenses in support of sustaining U.S. nuclear power and decarbonization face this climate hazard and may require capital investment adjustments, Moody’s said, as companies such as Duke Energy climate report respond to investor pressure for climate transparency.

“Some of these investments will help prepare for the increasing severity and frequency of extreme weather events, highlighting that the US electric grid is not designed for climate impacts today.”

Shocking scam: fraudster pretending to be from BC Hydro attempts to extort business

BC Hydro Bitcoin Scam targets small businesses with utility impersonation, call spoofing, and disconnection threats, demanding prepaid cards, cash cards, or bitcoin. Learn payment policies and key warning signs to avoid costly power shutoffs.

 

Key Points

A phone fraud where impostors threaten power disconnection and demand immediate payment via bitcoin or prepaid cards.

✅ Demands bitcoin, cash cards, or prepaid credit within minutes

✅ Uses caller ID spoofing and utility impersonation tactics

✅ BC Hydro never takes bitcoin or prepaid cards for bills

 

'I've gotta give him very high marks for being a good scammer,' says almost-fooled business owner

It's an old scam with a new twist.

Fraudsters pretending to be BC Hydro representatives are threatening to disconnect small business owners' power, mirroring Toronto Hydro scam warnings recently, unless they send in cash cards, prepaid credit cards or even bitcoin right away.

Colin Mackintosh, owner of Trans National Art in Langley, B.C., said he almost was fooled by one such scammer.

It was just before quitting time on Thursday at his shop when he got an unpleasant phone call.

"The phone rings. My partner hands me the phone and this fellow says to me that he's outside, he works with BC Hydro and he has a disconnect notice," Mackintosh said.

The caller, Mackintosh said, claimed that if an immediate payment wasn't made they'd cut off the company's power.

'Very well done'

BC Hydro says the scam has been around for a while, and amid commercial power use during COVID-19 in B.C., demanding payment in bitcoin is a new wrinkle.

Fraudsters mostly target small businesses because losing their power for a day or two would be a huge financial hit, a spokesperson said.

Mackintosh said the scammer knew all about the business. His number even showed up as BC Hydro on the call display, and the utility has faced scrutiny in a regulator report unrelated to such scams.

"He had all the answers to every question I seemed to have for him.  Very professional. Very well done. I've gotta give him very high marks for being a good scammer," Mackintosh said.

The caller demanded Mackintosh make an immediate payment at the nearest BC Hydro kiosk. Mackintosh was directed to drive to a certain address to make the payment.

He was ready to pay hundreds of dollars but when he got to the address, there was no kiosk: just a tire shop and inside something that looked like a cash machine but was actually a bitcoin ATM.

"At the very top of it, in little letters, it said 'Bit Coin,'" Mackintosh said. "As soon as I saw those two words, I told him in two expressive words what I thought of him and I hung up the phone."

 

Scam increasing

BC Hydro spokesperson Mora Scott said fraudsters target small businesses because their livelihoods depend on power, and customers face pressures highlighted in a deferred costs report as well.

"Fraudsters will reach out to our customers pretending to be B.C. Hydro representatives," said Scott.

"They'll demand an immediate payment or they'll disconnect their power. This did start to surface around 2015 but we have seen an increase recently."

Scott said that BC Hydro will never ask for banking information over the phone and does not accept cash card, prepaid credit cards or bitcoin as payment, and customers can consult BC Hydro bill relief for legitimate assistance.

Tesla (TSLA) Wants to Become an Electricity Retailer

Tesla Energy Ventures Texas enters the deregulated market as a retail electricity provider, leveraging ERCOT, battery storage, solar, and grid software to enable virtual power plants and customer energy trading with Powerwall and Megapack assets.

 

Key Points

Tesla Energy Ventures Texas is Tesla's retail power unit selling grid and battery energy and enabling solar exports.

✅ ERCOT retail provider; sells grid and battery-stored power

✅ Uses Powerwall/Megapack; supports virtual power plants

✅ Targets Tesla owners; enables solar export and trading

 

Last week, Tesla Energy Ventures, a new subsidiary of electric car maker Tesla Inc. (TSLA), filed an application to become a retail electricity provider in the state of Texas. According to reports, the company plans to sell electricity drawn from the grid to customers and from its battery storage products. Its grid transaction software may also enable customers for its solar panels to sell excess electricity back to the smart grid in Texas.1

For those who have been following Tesla's fortunes in the electric car industry, the Palo Alto, California-based company's filing may seem baffling. But the move dovetails with Tesla's overall ambitions for its renewable energy business, as utilities face federal scrutiny of climate goals and electricity rates.

Why Does Tesla Want to Become an Electricity Provider?
The simple answer to that question is that Tesla already manufactures devices that produce and store power. Examples of such devices are its electric cars, which come equipped with lithium ion batteries, and its suite of battery storage products for homes and enterprises. Selling power generated from these devices to consumers or to the grid is a logical next step.


Tesla's move will benefit its operations. The filing states that it plans to build a massive battery storage plant near its manufacturing facility in Austin. The plant will provide the company with a ready and cheap source of power to make its cars.

Tesla's filing should also be analyzed in the context of the Texas grid. The state's electricity market is fully deregulated, unlike regions debating grid privatization approaches, and generated about a quarter of its overall power from wind and solar in 2020.2 The Biden administration's aggressive push toward clean energy is only expected to increase that share.

After a February fiasco in the state grid resulted in a shutdown of renewable energy sources and skyrocketing natural gas prices, Texas committed to boosting the role of battery storage in its grid. The Electricity Reliability Council of Texas (ERCOT), the state's grid operator, has said it plans to install 3,008 MW of battery storage by the end of 2022, a steep increase from the 225 MW generated at the end of 2020.3 ERCOT's proposed increase in installation represents a massive market for Tesla's battery unit.

Tesla already has considerable experience in this arena. It has built battery storage plants in California and Australia and is building a massive battery storage unit in Houston, according to a June Bloomberg report.4 The unit is expected to service wholesale power producers. Besides this, the company plans to "drum up" business among existing customers for its batteries through an app and a website that will allow them to buy and sell power among themselves, a model also being explored by Octopus Energy in international talks.

Tesla Energy Ventures: A Future Profit Center?
Tesla's foray into becoming a retail electricity provider could boost the top line for its energy services business, even as issues like power theft in India highlight retail market challenges. In its last reported quarter, the company stated that its energy generation and storage business brought in $810 million in revenues.

Analysts have forecast a positive future for its battery storage business. Alex Potter from research firm Piper Sandler wrote last year that battery storage could bring in more than $200 billion per year in revenue and grow up to a third of the company's overall business.5

Immediately after the news was released, Morningstar analyst Travis Miller wrote that Tesla does not represent an immediate threat to other major players in Texas's retail market, where providers face strict notice obligations illustrated when NT Power was penalized for delayed disconnection notices, such as NRG Energy, Inc. (NRG) and Vistra Corp. (VST). According to him, the company will initially target its own customers to "complement" its offerings in electric cars, battery, charging, and solar panels.6

Further down the line, however, Tesla's brand name and resources may work to its advantage. "Tesla's brand name recognition gives it an advantage in a hypercompetitive market," Miller wrote, adding that the car company's entry confirmed the firm's view that consumer technology or telecom companies will try to enter retail energy markets, where policy shifts like Ontario rate reductions can shape customer expectations.

Cheap material converts heat to electricity

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

 

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

 

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

Energy UK - Switching surge continues

UK Energy Switching Surge sees 600,000 customers change suppliers in October, driven by competition, the Energy Switch Guarantee, and better tariffs, with Electralink's DTN supporting customer switching and Ofgem oversight.

 

Key Points

A rise in UK customers switching electricity suppliers in October, driven by competition and the Energy Switch Guarantee.

✅ 600,000 switches recorded in October

✅ 32% moved to small and mid-tier suppliers

✅ Energy Switch Guarantee assures simple, safe transfers

 

More than 600,000 customers took steps to save on their energy bills this winter by switching electricity provider in October, as forecasts such as a 16% bill decrease in April offer further encouragement, the latest figures from Energy UK reveal.

A third (32 per cent) of those changing providers in October moved to small and mid-tier suppliers.

Regional markets have seen changes too, including Irish electricity price increases that highlight wider cost pressures.

With recent research showing that that nine in ten energy switchers were happy with the process of changing suppliers and with the reassurance provided by the Energy Switch Guarantee - a series of commitments ensuring switches are simple, speedy and safe - and amid MPs proposing price restrictions to protect consumers, more and more customers are now confident when looking to move.

Lawrence Slade, chief executive of Energy UK said: 'Switching continues to surge with over 600,000 customers changing supplier to find a better deal last month. Many more will have made savings by checking they are on the best deal with their current supplier. It only takes a few minutes to do this and with over 55 suppliers across the market, there's never been more competition or choice.'

Around 75 per cent of the market are signatories of the Guarantee. This includes: British Gas, Bulb Energy, E.ON, EDF Energy, First Utility, Flow Energy, npower, Octopus Energy, Pure Planet, Sainsbury's Energy, Scottish Power, So Energy and Tonik Energy.

The switching data is supplied by Electralink who provides a secure service to transfer data between the electricity market participants. The company operates the Data Transfer Network (DTN) which underpins customer switching, meter interoperability and other business processes critical to a competitive electricity market, where knowing where your electricity comes from can support informed choices.

The data referenced in these reports is since our collection of data only and is for electricity only.

These figures do not include internal electricity switching, and statistics on this from the larger suppliers and on Standard Variable Tariffs can be viewed on the Ofgem website, while ministers consider ending the gas-electricity price link to reduce bills.
