A panel studying a deadly power plant explosion wants state regulators to consider stronger licensing and training rules on a common industrial pipe-cleaning practice used nationwide.

If adopted, the regulations would make Connecticut the first state to add extra oversight to the "gas blow" procedure, in which high-pressure natural gas is blown through pipes in some power plants and factories to clear debris.

Five workers were killed instantly and a sixth man died later of injuries from the February 7 blast at the under-construction Kleen Energy Systems plant in Middletown.

The plant exploded when something ignited the 400,000 cubic feet of gas and air that had accumulated in tight quarters during the gas blow procedure. The ignition source is still under investigation.

Retired U.S. District Court Judge Alan Nevas, chairman of the Connecticut panel that issued its recommendations Thursday, said government agency leaders in the group found that permits were in place for all of the regulated procedures at the plant.

But they also discovered that state law doesn't require special training, licensing or oversight for employees performing the gas blow — and their research found no such special regulations in other states, he said.

"This is a process that appears, to me at least, to have fallen between the cracks," Nevas said. "We live in a very highly regulated society, and to find that this was not regulated was surprising."

The law doesn't require companies to notify regulators and nearby residents before performing a gas blow.

It also doesn't address whether materials used have to meet certain standards, whether it should be prohibited during certain weather conditions that could affect how the gas disperses, and whether workers' hours should be limited so they aren't fatigued when they start the procedure.

State reviews of work records from contractors at the Kleen Energy plant found a majority of workers were on the job for more than 40 hours a week, and that some worked as many as 90 hours per week.

Linda Agnew, acting commissioner of the state Department of Labor, said there are no laws limiting work hours at private workplaces. She said their review found minor violations in record-keeping, but nothing suggesting those violations could be blamed for the long work hours or blast.

Gov. M. Jodi Rell created the panel to review the explosion and make recommendations to a second commission, which now receives the report that was just finalized. The second commission will report to Connecticut legislators in time for possible action in the 2011 legislative session, which starts in January.

Kleen Energy's permit for its Middletown plant construction expires November 30 of this year, so no new laws would be in place before it applies for renewal or an extension.

The panel advised the Connecticut Siting Council, which handles those permits, to include its recommendations as mandatory conditions if it renews the Kleen Energy permits.

Middletown detectives and state police are investigating whether any people or businesses should face criminal charges in connection with the explosion and deaths.

Robert Reardon, one of four attorneys representing 10 injured and deceased workers in civil lawsuits, said there is "no question in our minds" that the blast could have been avoided if the general contractor had faced the kind of stricter regulations that the commission advised.

"I think that the commission is on the right track. Unfortunately, sometimes industry has to be regulated by the state and federal government when they fail to regulate themselves properly, and this is one of these instances," Reardon said.

The U.S. Chemical Safety Board, which criticizes gas blows as inherently unsafe, also is investigating and plans to hold a June 28 public hearing in Portland, Conn., about dangers and alternatives to the procedure.

Several other industrial accidents involving natural gas have occurred in recent years, including one that killed four people last year at the ConAgra Foods Inc. plant in Garner, North Carolina, and another in 1999 at a Ford Motor Co. power plant in Dearborn, Michigan, that killed six.

Egypt Plans Power Link to Saudis in $1.6 Billion Project

Egypt-Saudi Electricity Interconnection enables cross-border power trading, 3,000 MW capacity, and peak-demand balancing across the Middle East, boosting grid stability, reliability, and energy security through an advanced electricity network, interconnector infrastructure, and GCC grid integration.

 

Key Points

A 3,000 MW grid link letting Egypt and Saudi Arabia trade power, balance peak demand, and boost regional reliability.

✅ $1.6B project; Egypt invests ~$600M; 2-year construction timeline

✅ 3,000 MW capacity; peak-load shifting; cross-border reliability

✅ Links GCC grid; complements Jordan and Libya interconnectors

 

Egypt will connect its electricity network to Saudi Arabia, joining a system in the Middle East that has allowed neighbors to share power, similar to the Scotland-England subsea project that will bring renewable power south.

The link will cost about $1.6 billion, with Egypt paying about $600 million, Egypt’s Electricity Minister Mohamed Shaker said Monday at a conference in Cairo, as the country pursues a smart grid transformation to modernize its network. Contracts to build the network will be signed in March or April, and construction is expected to take about two years, he said. In times of surplus, Egypt can export electricity and then import power during shortages.

"It will enable us to benefit from the difference in peak consumption,” Shaker said. “The reliability of the network will also increase.”

Transmissions of electricity across borders in the Gulf became possible in 2009, when a power grid connected Qatar, Kuwait, Saudi Arabia and Bahrain, a dynamic also seen when Ukraine joined Europe's grid under emergency conditions. The aim of the grid is to ensure that member countries of the Gulf Cooperation Council can import power in an emergency. Egypt, which is not in the GCC, may have been able to avert an electricity shortage it suffered in 2014 if the link with Saudi Arabia existed at the time, Shaker said.

The link with Saudi Arabia should have a capacity of 3,000 megawatts, he said. Egypt has a 450-megawatt link with Jordan and one with Libya at 200 megawatts, the minister said. Egypt will seek to use its strategic location to connect power grids in Asia, where the Philippines power grid efforts are raising standards, and elsewhere in Africa, he said.

In 2009, a power grid linked Qatar, Kuwait, Saudi Arabia and Bahrain, allowing the GCC states to transmit electricity across borders, much like proposals for a western Canadian grid that aim to improve regional reliability.

The Need for Electricity During the COVID-19 Pandemic

US utilities COVID-19 resilience shows electric utilities maintaining demand stability, reaffirming earnings guidance, and accessing the bond market for low-cost financing, as Dominion, NextEra, and Con Edison manage recession risks.

 

Key Points

It is the sector's capacity to sustain demand, financing access, and guidance despite pandemic recession pressures.

✅ Bond market access locks in low-cost, long-term debt

✅ Stable residential load offsets industrial weakness

✅ Guidance largely reaffirmed by major utilities

 

Dominion Energy (D) expects "incremental residential load" gains, consistent with COVID-19 electricity demand patterns, as a result of COVID-19 fallout. Southern Company CEO Tom Fanning says his company is "nowhere near" a need to review earnings guidance because of a potential recession, in a region where efficiency and demand response can help level electricity demand for years.

Sempra Energy (SRE) has reaffirmed earnings per share guidance for 2020 and 2021, as well timing for the sale of assets in Chile and Peru, and peers such as Duke Energy's renewables plan have reaffirmed capital investments to deliver cleaner energy and economic growth. And Xcel Energy (XEL) says it still "hasn’t seen material impact on its business."

Several electric utilities have demonstrated ability to tap the bond market, in line with utility sector trends in recent years, to lock in low-cost financing, as America moves toward broader electrification, despite ongoing turmoil. Their ranks include Dominion Energy, renewable energy leader NextEra Energy (NEE) and Consolidated Edison (ED), which last week sold $1 billion of 30-year bonds at a coupon rate of just 3.95 percent.

It’s still early days for US COVID-19 fallout. And most electric companies have yet to issue guidance. That’s understandable, since so much is still unknown about the virus and the damage it will ultimately do to human health and the global economy. But so far, the US power industry is showing typical resilience in tough times, as it coordinates closely with federal partners to maintain reliability.

Will it last? We won’t know for certain until there’s a lot more data. NextEra is usually first to report its Q1 earnings reports and detailed guidance. But that’s not expected until April 23. And companies may delay financials further, should the virus and efforts to control it impede collection and analysis of data, and as they address electricity shut-off risks affecting customers.

Ontario Teachers Pension Plan agrees to acquire a 25% stake in SSEN Transmission

Ontario Teachers SSEN Transmission Investment advances UK renewable energy, with a 25% minority stake in SSE plc's electricity transmission network, backing offshore wind, grid expansion, and Net Zero 2050 goals across Scotland and UK.

 

Key Points

A 25% stake by Ontario Teachers in SSE's SSEN Transmission to fund UK grid upgrades and accelerate renewables.

✅ £1,465m cash for 25% minority stake in SSEN Transmission

✅ Supports offshore wind, grid expansion, and Net Zero targets

✅ Partnering SSE plc to deliver clean, affordable power in the UK

 

Ontario Teachers’ Pension Plan Board (‘Ontario Teachers’) has reached an agreement with Scotland-based energy provider SSE plc (‘SSE’) to acquire a 25% minority stake in its electricity transmission network business, SSEN Transmission, to provide clean, affordable renewable energy to millions of homes and businesses across the UK, reflecting how clean-energy generation powers both the economy and the environment.

The transaction is based on an effective economic date of 31 March 2022, and total cash proceeds of £1,465m for the 25% stake are expected at completion. The transaction is expected to complete shortly.

Measures such as Ontario's 2021 electricity rate reductions have aimed to ease costs for businesses, informing broader discussions on affordability.

SSEN Transmission, which operates under its licenced entity, Scottish Hydro Electric Transmission plc, transports electricity generated from renewable resources – including onshore and offshore wind and hydro – from the north of Scotland across more than a quarter of the UK land mass amid scrutiny of UK electricity and gas networks profits under the regulatory regime. The investment by Ontario Teachers’ will help support the UK Government’s Net Zero 2050 targets, including the delivery of 50GW of offshore wind capacity by 2030.

Charles Thomazi, Senior Managing Director, Head of EMEA Infrastructure & Natural Resources, from Ontario Teachers’ said, noting that in Canada decisions like the OEB decision on Hydro One's T&D rates guide utility planning:

“SSEN Transmission is one of Europe’s fastest growing transmission networks. Its network stretches across some of the most challenging terrain in Scotland – from the North Sea and across the Highlands – to deliver safe, reliable, renewable energy to demand centres across the UK.

We’re delighted to partner again with SSE and are committed to supporting the growth of its network and the vital role it plays in the UK’s green energy revolution.”

Investor views on regulated utilities can diverge, as illustrated by analyses of Hydro One's investment outlook that weigh uncertainties and risk factors.

Rob McDonald, Managing Director of SSEN Transmission, said:

“With the north of Scotland home to the UK’s greatest resources of renewable electricity we have a critical role to play in helping deliver the UK and Scottish Governments net zero commitments.  Our investments will also be key to securing the UK’s future energy independence through enabling the deployment of homegrown, affordable, low carbon power.

“With significant growth forecast in transmission, bringing in Ontario Teachers’ as a minority stake partner will help fund our ambitious investment plans as we continue to deliver a network for net zero emissions across the north of Scotland.” 

Ontario Teachers’ Infrastructure & Natural Resources group invests in electricity infrastructure worldwide to accelerate the energy transition with current investments including Caruna, Finland’s largest electricity distributor, Evoltz, a leading electricity transmission platform in Brazil, and Spark Infrastructure, which invests in essential energy infrastructure in Australia to serve over 5 million homes and businesses.

In Ontario, distribution consolidation has included the sale of Peterborough Distribution to Hydro One for $105 million, illustrating ongoing sector realignment.

UK Emergency energy plan not going ahead

National Grid Demand Flexibility Service helps stabilise the UK grid during tight supply, offering discounts for smart meter users who shift peak-time electricity use, reducing power cut risks amid low wind and import constraints.

 

Key Points

A National Grid scheme paying smart homes to cut peak-time use, easing supply pressure and avoiding power cuts.

✅ Pays volunteers with smart meters to reduce peak demand.

✅ Credits discounts for shifting use to off-peak windows.

✅ Manages tight margins and helps avert UK power cuts.

 

National Grid has decided not to activate a scheme on Tuesday to help the UK avoid power cuts after being poised to do so.

It would have seen some households offered discounts on their electricity bills if they cut peak-time use.

National Grid had been ready to trigger the scheme following a warning that Britain's energy supplies were looking tighter than usual this week.

However, it decided that the measure was not required.

Alerts are sent out automatically when expected supplies drop below a certain level. But they do not mean that blackouts are likely, or that the situation is critical.

National Grid said it was "confident" it would be able to manage margins and "demand is not at risk".

Discounts
Earlier on Monday, the grid operator said it was considering whether to pay households across Britain to reduce their energy use to help out on Tuesday evening.

Under the Demand Flexibility Service (DFS), announced earlier this month, customers that have signed up could get discounts on their bills if they use less electricity in a given window of time.

That could mean delaying the use of a tumble-dryer or washing machine, or cooking dinner in the microwave rather than the oven.

Major suppliers such as Octopus and British Gas are taking part, but only customers that have an electricity smart meter and that have volunteered are eligible. About 14 million UK homes have an electricity smart meter.

The DFS has already been tested twice but has not yet run live.

Octopus, the supplier with the most customers signed up, said that some households had earned more than £4 during the hour-long tests, while the average saving was "well over £1".

It came after forecasts projected a large drop in the amount of power that Britain will be able to import from French nuclear power stations on Monday and Tuesday evenings.

The lack of strong winds to power turbines has also affected how much power can be generated within the UK, and efforts to fast-track grid connections aim to ease constraints.

Such warnings are not unusual - around 12 have been issued and cancelled without issue in the last six years, and other regions such as Canada are seeing grids strained by harsh weather as well.

However, they have become more common this year due to the energy crisis, and the most recent notice was sent out last week.

The situation means that the UK will have to import electricity from other sources on Monday and Tuesday evening.

Supplies are also expected be tight in France, forecasters say.

France has been facing months of problems with its nuclear power plants, which generate around three-quarters of the country's electricity.

More than half of the nuclear reactors run by state energy company EDF have closed due to maintenance problems and technical issues.

It has added to a massive energy crisis in Europe which is facing a winter without gas supplies from Russia.

More people are climbing dangerous hydro dams and towers in search of 'social media glory,' utility says

BC Hydro Trespassing Surge highlights risky social media stunts at dams and power stations, with restricted areas breached for selfies, electrocution hazards ignored, and safety signage violated across Buntzen Lake, Jones Lake, and Jordan River.

 

Key Points

A spike in illegal entries at BC Hydro sites for social media, increasing electrocution and drowning risks.

✅ 200% rise in trespassing over five years

✅ Risks: electrocution, drowning, deadly falls

✅ Obey signage; avoid restricted dam and substation areas

 

More and more daredevils are climbing onto dangerous dams and power stations to gain likes and social media followers, according to a new report from BC Hydro.

The power provider says it's seen a 200 per cent uptick in trespassing into restricted areas over the past five years, with many of the incidents posted onto sites like YouTube, Facebook and Instagram.

"It's concerning for us because our infrastructure has risk with it," said David Conway, a community relations manager for BC Hydro.

"There's a risk of electrocution in regards to our transmission towers and our substations ... and people can be severely injured, as seen in serious injuries cases, or killed," he said.

The company released a report Tuesday, noting specific incidents of users trespassing onto sites at Buntzen Lake in Anmore, Jones Lake in the Fraser Valley and Jordan River near Victoria; it has also been issuing Site C updates during the pandemic. The incidents ranged from climbing transmission towers to swimming in restricted areas at dam sites.

In a separate matter, an external investigation at Manitoba Hydro has examined alleged assaults by workers.

Conway says annual incidents climbed from a handful to about one dozen, but BC Hydro expects the figures to be even higher. He says many more events likely go unreported.

The report ties the increase in incidents to the pursuit of "social media glory." Between 2011 and 2017, at least 259 people were killed worldwide in selfie-related incidents, according to the Journal of Family Medicine and Primary Care, and a knowledge gap in electrical safety remains a factor. Many of the incidents involved water, electrical equipment or dangerous heights.

In 2018, three social media personalities died after falling off a cliff at Shannon Falls near Squamish, B.C.

North Shore Rescue attributes about 30 per cent of its calls to outdoor users attempting to capture content for social media.

Survey results highlighted in the BC Hydro report show that 15 per cent of British Columbians admit to putting themselves in a dangerous position "to achieve the 'perfect' shot."

Awareness also influences careers, as many young Canadians say they would work in electricity if they knew more.

The survey was conducted online by 800 B.C. residents. For comparison purposes, a probability sample of the same size would yield a margin of error of plus or minus 3.5 per cent, 19 times out of 20.

During the pandemic, the U.S. grid overseer issued a coronavirus warning to highlight operational risks.

Risky activities include standing at the edge of a cliff, knowingly disobeying safety signage or trespassing, or taking a selfie from a dangerous height.

Two per cent of British Columbians admit to injuring themselves in the name of a selfie.

"We want people to stay safe. We want to remind the public to stay a safe distance away from our infrastructure, and follow safety guidance near downed lines, as electricity and generating facilities can be dangerous," said Conway.

BC Hydro is urging all visitors to obey signage, steer clear of power-generating equipment and to stay on designated trails.

A new approach finds materials that can turn waste heat into electricity

Thermoelectric Materials convert waste heat into electricity via the Seebeck effect; quantum computations and semiconductors accelerate discovery, enabling clean energy, higher efficiency, and scalable heat-to-power conversion from abundant, non-toxic, cost-effective compounds.

 

Key Points

Thermoelectric materials turn waste heat into electricity via the Seebeck effect, improving energy efficiency.

✅ Convert waste heat to electricity via the Seebeck effect

✅ Quantum computations rapidly identify high-performance candidates

✅ Target efficient, low-thermal-conductivity, non-toxic, abundant compounds

 

The need to transition to clean energy is apparent, urgent and inescapable. We must limit Earth’s rising temperature to within 1.5 C to avoid the worst effects of climate change — an especially daunting challenge in the face of the steadily increasing global demand for energy and the need for reliable clean power, with concepts that can generate electricity at night now being explored worldwide.

Part of the answer is using energy more efficiently. More than 72 per cent of all energy produced worldwide is lost in the form of heat, and advances in turning thermal energy into electricity could recover some of it. For example, the engine in a car uses only about 30 per cent of the gasoline it burns to move the car. The remainder is dissipated as heat.

Recovering even a tiny fraction of that lost energy would have a tremendous impact on climate change. Thermoelectric materials, which convert wasted heat into useful electricity, can help, especially as researchers pursue low-cost heat-to-electricity materials for scalable deployment.

Until recently, the identification of these materials had been slow. My colleagues and I have used quantum computations — a computer-based modelling approach to predict materials’ properties — to speed up that process and identify more than 500 thermoelectric materials that could convert excess heat to electricity, and help improve energy efficiency.


Making great strides towards broad applications
The transformation of heat into electrical energy by thermoelectric materials is based on the “Seebeck effect.” In 1826, German physicist Thomas Johann Seebeck observed that exposing the ends of joined pieces of dissimilar metals to different temperatures generated a magnetic field, which was later recognized to be caused by an electric current.

Shortly after his discovery, metallic thermoelectric generators were fabricated to convert heat from gas burners into an electric current. But, as it turned out, metals exhibit only a low Seebeck effect — they are not very efficient at converting heat into electricity.

In 1929, the Russian scientist Abraham Ioffe revolutionized the field of thermoelectricity. He observed that semiconductors — materials whose ability to conduct electricity falls between that of metals (like copper) and insulators (like glass) — exhibit a significantly higher Seebeck effect than metals, boosting thermoelectric efficiency 40-fold, from 0.1 per cent to four per cent.

This discovery led to the development of the first widely used thermoelectric generator, the Russian lamp — a kerosene lamp that heated a thermoelectric material to power a radio.


Are we there yet?
Today, thermoelectric applications range from energy generation in space probes to cooling devices in portable refrigerators, and include emerging thin-film waste-heat harvesters for electronics as well. For example, space explorations are powered by radioisotope thermoelectric generators, converting the heat from naturally decaying plutonium into electricity. In the movie The Martian, for example, a box of plutonium saved the life of the character played by Matt Damon, by keeping him warm on Mars.

In the 2015 film, The Martian, astronaut Mark Watney (Matt Damon) digs up a buried thermoelectric generator to use the power source as a heater.

Despite this vast diversity of applications, wide-scale commercialization of thermoelectric materials is still limited by their low efficiency.

What’s holding them back? Two key factors must be considered: the conductive properties of the materials, and their ability to maintain a temperature difference, as seen in nighttime electricity from cold concepts, which makes it possible to generate electricity.

The best thermoelectric material would have the electronic properties of semiconductors and the poor heat conduction of glass. But this unique combination of properties is not found in naturally occurring materials. We have to engineer them, drawing on advances such as carbon nanotube energy harvesters to guide design choices.

Searching for a needle in a haystack
In the past decade, new strategies to engineer thermoelectric materials have emerged due to an enhanced understanding of their underlying physics. In a recent study in Nature Materials, researchers from Seoul National University, Aachen University and Northwestern University reported they had engineered a material called tin selenide with the highest thermoelectric performance to date, nearly twice that of 20 years ago. But it took them nearly a decade to optimize it.

To speed up the discovery process, my colleagues and I have used quantum calculations to search for new thermoelectric candidates with high efficiencies. We searched a database containing thousands of materials to look for those that would have high electronic qualities and low levels of heat conduction, based on their chemical and physical properties. These insights helped us find the best materials to synthesize and test, and calculate their thermoelectric efficiency.

We are almost at the point where thermoelectric materials can be widely applied, but first we need to develop much more efficient materials. With so many possibilities and variables, finding the way forward is like searching for a tiny needle in an enormous haystack.

Just as a metal detector can zero in on a needle in a haystack, quantum computations can accelerate the discovery of efficient thermoelectric materials. Such calculations can accurately predict electron and heat conduction (including the Seebeck effect) for thousands of materials and unveil the previously hidden and highly complex interactions between those properties, which can influence a material’s efficiency.

Large-scale applications will require themoelectric materials that are inexpensive, non-toxic and abundant. Lead and tellurium are found in today’s thermoelectric materials, but their cost and negative environmental impact make them good targets for replacement.

Quantum calculations can be applied in a way to search for specific sets of materials using parameters such as scarcity, cost and efficiency, and insights can even inform exploratory devices that generate electricity out of thin air in parallel fields. Although those calculations can reveal optimum thermoelectric materials, synthesizing the materials with the desired properties remains a challenge.

A multi-institutional effort involving government-run laboratories and universities in the United States, Canada and Europe has revealed more than 500 previously unexplored materials with high predicted thermoelectric efficiency. My colleagues and I are currently investigating the thermoelectric performance of those materials in experiments, and have already discovered new sources of high thermoelectric efficiency.

Those initial results strongly suggest that further quantum computations can pinpoint the most efficient combinations of materials to make clean energy from wasted heat and the avert the catastrophe that looms over our planet.
