The United States' reliance on coal to generate almost half of its electricity, costs the economy about $345 billion a year in hidden expenses not borne by miners or utilities, including health problems in mining communities and pollution around power plants, a study found.

Those costs would effectively triple the price of electricity produced by coal-fired plants, which are prevalent in part due to the their low cost of operation, the study led by a Harvard University researcher found.

"This is not borne by the coal industry, this is borne by us, in our taxes," said Paul Epstein, a Harvard Medical School instructor and the associate director of its Center for Health and the Global Environment, the study's lead author.

"The public cost is far greater than the cost of the coal itself. The impacts of this industry go way beyond just lighting our lights."

Coal-fired plants currently supply about 45 percent of the nation's electricity, according to U.S. Energy Department data. Accounting for all the ancillary costs associated with burning coal would add about 18 cents per kilowatt hour to the cost of electricity from coal-fired plants, shifting it from one of the cheapest sources of electricity to one of the most expensive.

In the year that ended in November, the average retail price of electricity in the United States was about 10 cents per kilowatt hour, according to the Energy Department.

Advocates of coal power have argued that it is among the cheapest of fuel sources available in the United States, allowing for lower-cost power than that provided by the developing wind and solar industries.

"The Epstein article ignores the substantial benefits of coal in maintaining lower energy prices for American families and businesses," said Lisa Camooso Miller, a spokeswoman for the American Coalition for Clean Coal Electricity, an industry group. "Lower energy prices are linked to a higher standard of living and better health."

The estimate of hidden costs takes into account a variety of side effects of coal production and use. Among them are the cost of treading elevated rates of cancer and other illnesses in coal-mining areas, environmental damage and lost tourism opportunities in coal regions where mountaintop removal is practiced and climate change resulting from elevated emissions of carbon dioxide from burning the coal.

Coal releases more carbon dioxide when burned than does natural gas or oil.

The $345 billion annual cost figure was the study's best estimate of the costs associated with burning coal. The study said the costs could be as low as $175 billion or as high as $523 billion.

"This is effectively a subsidy borne by asthmatic children and rain-polluted lakes and the climate is another way of looking at it," said Kert Davies, research director with the environmental activist group Greenpeace. "It's a tax by the industry on us that we are not seeing in our bills but we are bearing the costs."

The estimates came in the paper "Full cost accounting for the life cycle of coal," to be published in the Annals of the New York Academy of Sciences. Epstein discussed his findings on the Arctic Sunrise, a 164-foot-long 50 meter long icebreaker operated by Greenpeace, and moored in Boston Harbor.

Leading users of coal in the United States include utilities American Electric Power Co Inc and Duke Energy Corp. The top producers include miners Arch Coal Inc, Consol Energy Inc, Peabody Energy Corp and Alpha Natural Resources.

Canadian Manufacturers and Exporters Congratulates the Ontario Government for Taking Steps to Reduce Electricity Prices

Ontario Global Adjustment Deferral offers COVID-19 electricity bill relief to industrial and commercial consumers not on the RPP, aligning GA to March levels for Class A and Class B manufacturers to improve cash flow.

 

Key Points

A temporary GA deferral easing electricity costs for Ontario industrial and commercial users not on the RPP.

✅ Sets Class B GA at $115/MWh; Class A gets equal percentage cut.

✅ Applies April-June 2020; automatic bill adjustments and credits.

✅ Deferred charges repaid over 12 months starting January 2021.

 

Manufacturers welcome the Government of Ontario's decision to defer a portion of Global Adjustment (GA) charges as part of support for industrial and commercial electricity consumers that do not participate in the Regulated Price Plan.

"Manufacturers are pleased the government listened to Canadian Manufacturers & Exporters (CME) member recommendations and is taking action to reduce Ontario electricity bills immediately," said Dennis Darby, President & CEO of CME.

"The majority of manufacturers have identified cash flow as their top concern during the crisis, "added Darby. "The GA system would have caused a nearly $2 billion cost surge to Ontario manufacturers this year. This new initiative by the government is on top of the billions in support already provided to help manufacturers weather this unprecedented storm, while other provinces accelerate British Columbia's clean energy shift to drive long-term competitiveness. All these measures are a great start in helping businesses of all sizes stay afloat during the crisis and, keeping Ontarians employed."

"We call on the Ontario government to continue to consider the impact of electricity costs on the manufacturing sector, even after the COVID-19 crisis is resolved," stated Darby. "High prices are putting Ontario manufacturers at a significant competitive disadvantage and, discourages investments." A recent report from London Economics International (LEI) found that when compared to jurisdictions with similar manufacturing industries, Ontario's electricity prices can be up to 75% more expensive, underscoring the importance of planning for Toronto's growing electricity needs to maintain affordability.

To provide companies with temporary immediate relief on their electricity bills, the Ontario government is deferring a portion of Global Adjustment (GA) charges for industrial and commercial electricity consumers that do not participate in the Regulated Price Plan (RPP), starting from April 2020, as some regions saw reduced electricity demand from widespread remote work during the pandemic. The GA rate for smaller industrial and commercial consumers (i.e., Class B) has been set at $115 per megawatt-hour, which is roughly in line with the March 2020 value. Large industrial and commercial consumers (i.e., Class A) will receive the same percentage reduction in GA charges as Class B consumers.

The Ontario government intends to keep this relief in place through the end of June 2020, alongside investments like smart grid technology in Sault Ste. Marie to support reliability, subject to necessary extensions and approvals to implement this initiative.

Industrial and commercial electricity consumers will automatically see this relief reflected on their bills. Consumers who have already received their April bill should see an adjustment on a future bill.

Related initiatives include developing cyber standards for electricity sector IoT devices to strengthen system security.

The government intends to bring forward subsequent amendments that would, if approved, recover the deferred GA charges (excluding interest) from industrial and commercial electricity consumers, as Toronto prepares for a surge in electricity demand amid continued growth, over a 12-month period beginning in January 2021.

Alberta ratepayers on the hook for unpaid gas and electricity bills from utility deferral program

Alberta Utility Rate Rider will add a modest fee to electricity bills and natural gas charges as the AUC recovers outstanding debt from the COVID-19 deferral program via AESO and the Balancing Pool.

 

Key Points

A temporary surcharge on Alberta power and gas bills to recover unpaid COVID-19 deferral debt, administered by the AUC.

✅ Applies per kWh and per GJ based on consumption

✅ Recovers unpaid balances from 2020-21 bill deferrals

✅ Collected via AESO and the Balancing Pool under AUC oversight

 

The province says Alberta ratepayers should expect to see an extra fee on their utility bills in the coming months.

That fee is meant to recover the outstanding debt owed to gas and electricity providers resulting from last year's three-month utility deferral program offered to struggling Albertans during the pandemic.

The provincial government announced the utility deferral program in March 2020 then formalized it with legislation, alongside a consumer price cap on power bills that shaped later policy decisions.

The program allowed residential, farm and small commercial customers who used less than 250,000 kilowatt hours of electricity per year — or consumed less than 2,500 gigajoules per year — to postpone their bills amid the COVID-19 pandemic.

According to the province, 350,000 customers, or approximately 13 per cent of the natural gas and electricity consumer base, took advantage of the program.

Customers had a year to repay providers what they owed. That deadline ended June 18, 2021.

The Alberta Utilities Commission (AUC), which regulates the utilities sector and natural gas and electricity markets and oversees a rate of last resort framework, said the vast majority of consumers have squared up.

But for those who didn't, provincial legislation dictates that Alberta ratepayers must cover any unpaid debt. The legislation exempts Medicine Hat utility customers for electricity and gas co-operative customers for gas.

"When the program was announced, it was very clear that it was a deferral program and that the monies would need to be paid back," said Geoff Scotton, a spokesperson with the Alberta Utilities Commission.

"Now we're in the situation where the providers, in good faith, who enabled those payment deferrals, need to be made whole. That's really the goal here."

Amount to be determined
Margeaux Maron, a spokesperson for Associate Minister of Natural Gas and Electricity Dale Nally, said based on early estimates, $13 to $16 million of $92 million in deferred payments remain outstanding.

As a result, the province expects the average Albertan will end up paying, unlike jurisdictions offering a lump-sum credit, a fraction of a dollar extra per monthly gas and electricity bill over a handful of months.

Scotton said at this point, there are too many unknown factors to know the exact size of the rate rider. However, he said he expects it to be modest.

Scotton said affected parties first have until the end of this week to notify the AUC exactly how much they are still owed.

Those parties include the Alberta Electric System Operator and the Balancing Pool, who essentially acted as bankers with respect to the distribution and transmission of the utilities to customers who deferred their payments.

Regulated service providers may also seek reimbursement on administrative and carrying costs, even as issues like a BC Hydro fund surplus spark debate elsewhere.

Then, Scotton said, once the outstanding amounts are known, the AUC will hold a public proceeding, similar to a Nova Scotia rate case, to determine the amount and the duration of the rate rider to be applied to each natural gas and electricity bill.

The amount will be based on consumption: per kilowatt hour for electricity and per gigajoule for natural gas.

That means larger businesses will end up paying more than the average Albertan.

Scotton said the AUC will expedite the hearing process and it expects to have a decision by the end of the summer.

Rate rider a 'surprise'
Joel MacDonald with Energyrates.ca — an organization which compares energy rates across the country — said it's not the amount of the rate rider that bothers him, but the fact that the repayment process wasn't made clear at the onset of the program.

"It came to us as a bit of a surprise," MacDonald said.

He said what was sold as a deferral program seems more like an electricity rebate program, or an "ability to pay" program.

"As opposed to the retailers looking into collection methods, anything that wasn't paid is basically just being forced upon all Alberta consumers," MacDonald said.

The expectation set out in the deferral legislation and regulations state utility providers such as Enmax and Epcor are expected to use reasonable efforts to try to collect the unpaid balances. It must then detail those reasonable efforts to the AUC.

A spokesperson for Enmax said it first works with its customers to find manageable payment arrangements and connects them with support services if they are unable to pay.

Then, if payment can't be arranged, it said it will work with a collection agency, which may even result in disconnection of service.

The spokesperson said only after all efforts have failed would Enmax seek reimbursement through this program.

Use tax revenues?
MacDonald also questioned why a government program isn't being paid for through general tax revenues.

He compared the utility deferral program to a mortgage subsidy program.

"Imagine that [Canada Mortgage And Housing Corporation] said, 'Hey, we had to give mortgage deferrals and some of these people never paid back their deferrals, so we're going to add an extra $300 to everyone's mortgage,'" he said.

"You'd expect that to come off of some sort of general taxation — not being assigned to other people's mortgages, right?"

In response, Maron said due to the current fiscal challenges facing the government — and the expected minimal costs to consumers, and even as a consumer price cap on electricity remains in place — it was determined that a rate rider would be an appropriate mechanism to repay bad debt associated with the program.

Scotton said rate riders aren't unusual — they're used to fine-tune rates for a set period of time.

He said under normal circumstances, regulated service providers can apply to the AUC to impose a rate rider to recover unexpected costs. And in some instances, they can provide a credit.

But in this situation, he said the debt is aggregated and, in turn, being collected more broadly.

CALIFORNIA: Why your electricity prices are soaring

California Electricity Prices are surging across PG&E, SCE, and SDG&E territories, driven by fixed grid costs, wildfire mitigation, CARE subsidies, and Net Energy Metering, burdening low-income renters and increasing statewide utility debt, CPUC reports show.

 

Key Points

High rates driven by fixed grid costs and policies, burdening low-income customers across PG&E, SCE, and SDG&E.

✅ Fixed costs: transmission, distribution, wildfire mitigation

✅ Solar NEM shifts grid costs onto remaining ratepayers

✅ CPUC, CARE, LIHEAP aim to relieve rising utility debt

 

California's electricity prices are among the highest in the country, new research says, and those costs are falling disproportionately on a customer base that's already struggling to pay their bills.

PG&E customers pay about 80 percent more per kilowatt-hour than the national average, according to a study by the energy institute at UC Berkeley's Haas Business School with the nonprofit think tank Next 10. The study analyzed the rates of the state's three largest investor-owned utilities and found that Southern California Edison charged 45 percent more than the national average, while San Diego Gas & Electric charged double. Even low-income residents enrolled in the California Alternate Rates for Energy program paid more than the average American.

"California's retail prices are out of line with utilities across the country," said UC Berkeley assistant professor and study co-author Meredith Fowlie, citing Hawaii and some New England states among the outliers with even higher rates. "And they're increasing, as regulators face calls for action across the state."


So why are prices so high?
One reason is that California's size and geography inflate the "fixed" costs of operating its electric system, even as the state considers revamping electricity rates to clean the grid in parallel, which include maintenance, generation, transmission, and distribution as well as public programs like CARE and wildfire mitigation, according to the study. Those costs don't change based on how much electricity residents consume, yet between 66 and 77 percent of Californians' electricity bills are used to offset the costs of those programs, the study found.

These are legitimate expenses, Fowlie said. However, because lower-income residents use only moderately less electricity than higher income households, they end up with a disproportionate share of the burden, according to the study. And while the bills of older, wealthier Californians continue to decrease as they adopt cost-efficient alternatives like the state's Net Energy Metering solar program and the resulting solar power cost shift dynamic, costs will keep rising for a shrinking customer base composed mostly of low- and middle-income renters who still use electricity as their main energy source.

"When households adopt solar, they're not paying their fair share," Fowlie said. While solar users generate power that decreases their bills, they still rely on the state's electric grid for much of their power consumption - without paying for its fixed costs like others do.

"As this continues it's going to make electricity even more unaffordable," said F. Noel Perry, founder of Next 10, which funds nonpartisan research on the economy and environment.

PG&E this month raised its electricity rates 3.7 percent, amounting to a $5.01 a month increase for the average residential customer, who now pays $138.85 a month for electricity. It was the second increase this year, as regulators consider major changes to electric bills statewide, said Mark Toney, executive director of The Utility Reform Network, who noted that higher rates are particularly difficult for those who have lost their jobs in the pandemic. The California Public Utilities Commission last year approved a PG&E plan for more incremental increases through Dec. 31, 2022.

PG&E spokesperson Kristi Jourdan said in an email statement that the company was committed to keeping prices as low as possible as the state weighs income-based flat-fee utility bills proposals, and that although some programs are meant to be subsidized through rates, "in other cases, given that some customers have greater access to energy alternatives, the remaining customers - often those with limited means - are left paying unintended subsidies."

The costs quickly became overwhelming for Fretea Sylver, who rents a small house in Castro Valley and lost much of her work as the owner of a small woodwork business early in the pandemic. "They're little tiny changes but they accumulate. You turn around and you're like wait a second, why is my bill $20 more?," Sylver said. "And you have to pay it, no matter what."

Many more are unable to pay. Between February and December of last year, Californians accumulated more than $650 million in late payments from their utility providers, according to an analysis by the CPUC. In 2019, utility debt fell $71,646,869 from the prior year.

Sylver, who was on unemployment for 10 months last year, accumulated over $600 in unpaid PG&E bills. "We sort of went into a bit of debt, having to use credit cards and loans to sustain what we had to pay for. We're trying to catch up," Sylver said. The family received some help from the federal Low-Income Home Energy Assistance Program, which provides up to $1,000 to those who are late on their utility bills.

The study identified improvements to make California's power grid more equitable, such as income-based fixed electricity charges for the grid's cost that are based on income. Republican state senators this week called on the state to use federal relief money to forgive the billions Californians owe in utility debt, even as some lawmakers move to overturn income-based utility charges amid ongoing debate. Californians are currently protected by a statewide moratorium on disconnection for nonpayment of electricity bills through June 30. The CPUC this month began taking public input on the issue of how to grant some relief to those who have fallen behind on their utility bills.

3 Reasons Why Cheap Abundant Electricity Is Getting Closer To Reality

Renewable Energy Breakthroughs drive quantum dots solar efficiency, Air-gen protein nanowires harvesting humidity, and cellulose membranes for flow batteries, enabling printable photovoltaics, 24/7 clean power, and low-cost grid storage at commercial scale.

 

Key Points

Advances like quantum dot solar, Air-gen, and cellulose flow battery membranes that improve clean power and storage.

✅ Quantum dots raise solar conversion efficiency, are printable

✅ Air-gen harvests electricity from humidity with protein nanowires

✅ Cellulose membranes cut flow battery costs, aid grid storage

 

Science never sleeps. The quest to find new and better ways to do things continues in thousands of laboratories around the world. Today, the global economy is based on the use of electricity, and one analysis shows wind and solar potential could meet 80% of US demand, underscoring what is possible. If there was a way to harness all the energy from the sun that falls on the Earth every day, there would be enough of electricity available to meet the needs of every man, woman, and child on the planet with plenty left over. That day is getting closer all the time. Here are three reasons why.

Quantum Dots Make Better Solar Panels
According to Science Daily, researchers at the University of Queensland have set a new world record for the conversion of solar energy to electricity using quantum dots — which pass electrons between one another and generate electrical current when exposed to solar energy in a solar cell device. The solar devices they developed have beaten the existing solar conversion record by 25%.

“Conventional solar technologies use rigid, expensive materials. The new class of quantum dots the university has developed are flexible and printable,” says professor Lianzhou Wang, who leads the research team. “This opens up a huge range of potential applications, including the possibility to use it as a transparent skin to power cars, planes, homes and wearable technology. Eventually it could play a major part in meeting the United Nations’ goal to increase the share of renewable energy in the global energy mix.”

“This new generation of quantum dots is compatible with more affordable and large-scale printable technologies,” he adds. “The near 25% improvement in efficiency we have achieved over the previous world record is important. It is effectively the difference between quantum dot solar cell technology being an exciting prospect and being commercially viable.” The research was published on January 20 in the journal Nature Energy.

Electricity From Thin Air
Science Daily also reports that researchers at UMass Amherst also have interesting news. They claim they created a device called an Air-gen, short for air powered generator. (Note: recently we reported on other research that makes electricity from rainwater.) The device uses protein nanowires created by a microbe called Geobacter. Those nanowires can generate electricity from thin air by tapping the water vapor present naturally in the atmosphere. “We are literally making electricity out of thin air. The Air-gen generates clean energy 24/7. It’s the most amazing and exciting application of protein nanowires yet,” researchers Jun Yao and Derek Lovely say. There work was published February 17 in the journal Nature.

The new technology developed in Yao’s lab is non-polluting, renewable, and low-cost. It can generate power even in areas with extremely low humidity such as the Sahara Desert. It has significant advantages over other forms of renewable energy including solar and wind, Lovley says, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind, and “it even works indoors,” a point underscored by ongoing grid challenges that slow full renewable adoption.

Yao says, “The ultimate goal is to make large-scale systems. For example, the technology might be incorporated into wall paint that could help power your home. Or, we may develop stand-alone air-powered generators that supply electricity off the grid, and in parallel others are advancing bio-inspired fuel cells that could complement such devices. Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production. This is just the beginning of a new era of protein based electronic devices.”

Improved Membranes For Flow Batteries From Cellulose
Storing energy is almost as important to decarbonizing the environment as making it in the first place, with the rise of affordable solar batteries improving integration.  There are dozens if not hundreds of ways to store electricity and they all work to one degree or another. The difference between which ones are commercially viable and ones that are not often comes down to money.

Flow batteries — one approach among many, including fuel cells for renewable storage — use two liquid electrolytes — one positively charged and one negatively charged — separated by a membrane that allows electrons to pass back and forth between them. The problem is, the liquids are highly corrosive. The membranes used today are expensive — more than $1,300 per square meter.

Phys.org reports that Hongli Zhu, an assistant professor of mechanical and industrial engineering at Northeastern University, has successfully created a membrane for use in flow batteries that is made from cellulose and costs just $147.68 per square meter. Reducing the cost of something by 90% is the kind of news that gets people knocking on your door.

The membrane uses nanocrystals derived from cellulose in combination with a polymer known as polyvinylidene fluoride-hexafluoropropylene.  The naturally derived membrane is especially efficient because its cellular structure contains thousands of hydroxyl groups, which involve bonds of hydrogen and oxygen that make it easy for water to be transported in plants and trees.

In flow batteries, that molecular makeup speeds the transport of protons as they flow through the membrane. “For these materials, one of the challenges is that it is difficult to find a polymer that is proton conductive and that is also a material that is very stable in the flowing acid,” Zhu says.

Cellulose can be extracted from natural sources including algae, solid waste, and bacteria. “A lot of material in nature is a composite, and if we disintegrate its components, we can use it to extract cellulose,” Zhu says. “Like waste from our yard, and a lot of solid waste that we don’t always know what to do with.”

Flow batteries can store large amounts of electricity over long periods of time — provided the membrane between the storage tanks doesn’t break down. To store more electricity, simply make the tanks larger, which makes them ideal for grid storage applications where there is often plenty of room to install them. Slashing the cost of the membrane will make them much more attractive to renewable energy developers and help move the clean energy revolution forward.

The Takeaway
The fossil fuel crazies won’t give up easily. They have too much to lose and couldn’t care less if life on Earth ceases to exist for a few million years, just so long as they get to profit from their investments. But they are experiencing a death of a thousand cuts. None of the breakthroughs discussed above will end thermal power generation all by itself, but all of them, together with hundreds more just like them happening every day, every week, and every month, even as we confront clean energy's hidden costs across supply chains, are slowly writing the epitaph for fossil fuels.

And here’s a further note. A person of Chinese ancestry is the leader of all three research efforts reported on above. These are precisely the people being targeted by the United States government at the moment as it ratchets up its war on immigrants and anybody who cannot trace their ancestry to northern Europe. Imagine for a moment what will happen to America when researchers like them depart for countries where they are welcome instead of despised.

London's Newest Electricity Tunnel Goes Live

London Electricity Tunnel strengthens grid modernization with high-voltage cabling from major substations, increasing redundancy, efficiency, and resilience while enabling renewable integration, optimized power distribution, and a stable, low-loss electricity supply across the capital.

 

Key Points

A high-voltage tunnel upgrading London's grid, with capacity, redundancy, and renewable integration for reliable power.

✅ High-voltage cabling from key substations boosts capacity

✅ Redundancy improves reliability during grid faults

✅ Enables renewable integration and lower transmission losses

 

London’s energy infrastructure has recently taken a significant leap forward with the commissioning of its newest electricity tunnel, and related upgrades like the 2GW substation that bolster transmission capacity, a project that promises to enhance the reliability and efficiency of the city's power distribution. This cutting-edge tunnel is a key component in London’s ongoing efforts to modernize its energy infrastructure, support its growing energy demands, and contribute to its long-term sustainability goals.

The newly activated tunnel is part of a broader initiative to upgrade London's aging power grid, which has faced increasing pressure from the city’s expanding population and its evolving energy needs, paralleling Toronto's electricity planning to accommodate growth. The tunnel is designed to carry high-voltage electricity from major substations to various parts of the city, improving the distribution network's capacity and reliability.

The construction of the tunnel was a major engineering feat, involving the excavation of a vast underground passage that stretches several kilometers beneath the city. The tunnel is equipped with advanced technology and materials to ensure its resilience and efficiency, and is informed by advances such as HVDC technology being explored across Europe for stronger grids. It features state-of-the-art cabling and insulation to handle high-voltage electricity safely and efficiently, minimizing energy losses and improving overall grid performance.

One of the key benefits of the new tunnel is its ability to enhance the reliability of London’s power supply. As the city continues to grow and demand for electricity increases, maintaining a stable and uninterrupted power supply is critical. The tunnel helps address this need by providing additional capacity and creating redundancy in the power distribution network, aligning with national efforts to fast-track grid connections that unlock capacity across the UK.

The tunnel also supports London’s sustainability goals by facilitating the integration of renewable energy sources into the grid. With the increasing use of solar, wind, and other clean energy technologies, including the Scotland-to-England subsea link that will carry renewable power, the power grid needs to be able to accommodate and distribute this energy effectively. The new tunnel is designed to handle the variable nature of renewable energy, allowing for a more flexible and adaptive grid that can better manage fluctuations in supply and demand.

In addition to its technical benefits, the tunnel represents a significant investment in London’s future energy infrastructure, echoing calls to invest in smarter electricity infrastructure across North America and beyond. The project has created jobs and stimulated economic activity during its construction phase, and it will continue to provide long-term benefits by supporting a more efficient and resilient power system. The upgrade is part of a broader strategy to modernize the city’s infrastructure and prepare it for future energy challenges.

The completion of the tunnel also reflects a commitment to addressing the challenges of urban infrastructure development. Building such a major piece of infrastructure in a densely populated city like London requires careful planning and coordination to minimize disruption and ensure safety. The project team worked closely with local communities and businesses to manage the construction process and mitigate any potential impacts.

As London moves forward, the new electricity tunnel will play a crucial role in supporting the city’s energy needs. It will help ensure that power is delivered efficiently and reliably to homes, businesses, and essential services. The tunnel also sets a precedent for future infrastructure projects, demonstrating how advanced engineering and technology can address the demands of modern urban environments.

The successful activation of the tunnel marks a significant milestone in London’s efforts to build a more sustainable and resilient energy system. It represents a forward-thinking approach to managing the city’s energy infrastructure and addressing the challenges posed by population growth, increasing energy demands, and the need for cleaner energy sources.

Looking ahead, London will continue to invest in and upgrade its energy infrastructure to support its ambitious climate goals and ensure a reliable power supply for its residents, a trend mirrored by Toronto's preparations for surging demand as that city continues to grow.
