Alaska Coal-Fired CHP Plant opens near Usibelli mine, supplying electricity and district heat to UAF; remote location without gas pipelines, low wind and solar potential, and high heating demand shaped fuel choice.

Key Points

A 17 MW coal CHP at UAF producing power and campus heat, chosen for remoteness and lack of gas pipelines.

✅ 17 MW generator supplying electricity and district heat

✅ Near Usibelli mine; limited pipeline access shapes fuel

✅ Alternative options like LNG, wind, solar not cost-effective

One way to boost coal in the US: Find a spot near a mine with no access to oil or natural gas pipelines, where it’s not particularly windy and it’s dark much of the year.

That’s how the first coal-fired plant to open in the U.S. since 2015 bucked the trend in an industry that’s seen scores of facilities close in recent years. A 17-megawatt generator, built for $245 million, is set to open in April at the University of Alaska Fairbanks, just 100 miles from the state’s only coal mine.

“Geography really drove what options are available to us,” said Kari Burrell, the university’s vice chancellor for administrative services, in an interview. “We are not saying this is ideal by any means.”

The new plant is arriving as coal fuels about 25 percent of electrical generation in the U.S., down from 45 percent a decade earlier, even as some forecasts point to a near-term increase in coal-fired generation in 2021. A near-record 18 coal plants closed in 2018, and 14 more are expected to follow this year, according to BloombergNEF.

The biggest bright spot for U.S. coal miners recently has been exports to overseas power plants. At home, one of the few growth areas has been in pizza ovens.

There are a handful of other U.S. coal power projects that have been proposed, including plans to build an 850 megawatt facility in Georgia and an 895 megawatt plant in Kansas, even as a Minnesota utility reports declining coal returns across parts of its portfolio. But Ashley Burke, a spokeswoman for the National Mining Association, said she’s unaware of any U.S. plants actively under development besides the one in Alaska.

Future of power

“The future of power in the U.S. does not include coal,” Tessie Petion, an analyst for HSBC Holdings Plc, said in a research note, a view echoed by regions such as Alberta retiring coal power early in their transition.

Fairbanks sits on the banks of the Chena River, amid the vast subarctic forests in the heart of Alaska. The oil and gas fields of the state’s North slope are 500 miles north. The nearest major port is in Anchorage, 350 miles south.

The university’s new plant is a combined heat and power generator, which will create steam both to generate electricity and heat campus buildings. Before opting for coal, the school looked into using liquid natural gas, wind and solar, bio-mass and a host of other options, as new projects in Southeast Alaska seek lower electricity costs across the region. None of them penciled out, said Mike Ruckhaus, a senior project manager at the university.

The project, financed with university and state-municipal bonds, replaces a coal plant that went into service in 1964. University spokeswoman Marmian Grimes said it’s worth noting that the new plant will emit fewer emissions.

The coal will come from Usibelli Coal Mine Inc., a family-owned business that produces between 1.2 and 2 million tons per year from a mine along the Alaska railroad, according to the company’s website.

While any new plant is good news for coal miners, Clarksons Platou Securities Inc. analyst Jeremy Sussman said this one is "an isolated situation."

“We think the best producers can hope for domestically is a slow down in plant closures,” he said, even as jurisdictions like Alberta close their last coal plant entirely.

India Power Sector Payment Crisis strains utilities with electricity theft, discom arrears, coal dues, and subsidy burdens, triggering outages, load-shedding, and tariff stress as record heatwave demand tests grid reliability, billing compliance, and infrastructure upgrades.

Key Points

Linked payment shortfalls, theft, and subsidies driving arrears, outages, and planning gaps across Indias power grid.

✅ Discom arrears surpass Rs 1 lakh crore, straining cash flow

✅ Coal India unpaid, fuel risk rises and tariffs face pressure

✅ Outages and load-shedding worsen amid heatwave demand spike

India is among the world leaders in losing money to electricity theft. The country’s power sector also has a peculiar pattern of entities selling without getting the money on time, or nothing at all, while Manitoba Hydro debt highlights similar strains elsewhere. Coal India is owed about Rs 12,300 crore by power generation companies, which themselves have not been paid over Rs 1 lakh crore by distribution companies. The figures of losses suffered by discoms are much higher, even as UK network profits have drawn criticism, underscoring divergent market outcomes. The circuit does get completed somehow, but the uneven transaction, which defies business sense, introduces a disruptive strand that limits the scope for any future planning. Regular and unannounced shutdowns become the norm as the power supply falls short of demand, which this time is expected to touch record highs of 215-220 gigawatts amid the scorching heatwave, and cases like deferred BC Hydro costs illustrate how financial pressures accumulate.

In debt-ridden Punjab, the power subsidy bill is over Rs 10,000 crore, a large portion of which serves farmers. The AAP government plans to provide free electricity up to 300 units for every household from July 1, even as power bill cuts in Thailand show alternative approaches to affordability. The generous giveaways cannot camouflage the state of affairs. Thirty-three government departments had outstanding electricity bills of Rs 62 crore as on March 31, the end of the last financial year. With arrears of Rs 22.48 crore, the biggest defaulter was the Water and Sanitation Department. According to the Punjab State Power Corporation Limited, around 40 police stations and posts have been found to be stealing power or failing to clear the bills, while utility impersonation scams target consumers elsewhere. Customary warnings have been issued of snapping supply if the dues are not paid, even as utility penalties for disconnection delays underscore enforcement challenges, but ‘public interest’ and ‘essential services’ will ensure that such an eventuality does not arise.

The substantial fine imposed on a dera stealing power in Tarn Taran, along with the registration of an FIR, is exemplary action that needs to be carried forward. Change is tough, but a new way of working begins with those in positions of power leading by example, be it fixing the payment mechanism, upgrading infrastructure with smart grid initiatives in mind, minimising the use of electricity or a gradual switch to alternative energy sources.

Ontario Peak Perks Program boosts energy efficiency with smart thermostats, demand response, and incentives, reducing peak demand, electricity costs, and emissions while supporting grid reliability and Save on Energy initiatives across Ontario businesses and homes.

Key Points

A demand response initiative offering incentives via smart thermostats to cut peak electricity use and lower costs

✅ $75 sign-up, $20 yearly enrollment incentive

✅ Up to 10 summer temperature events; opt-out anytime

✅ Expanded retrofits, greenhouse support, grid savings

The Ontario government is launching the new Peak Perks program to help families save money by conserving energy, building on bill support during COVID-19 initiatives as part of the government’s $342 million expansion of Ontario’s energy-efficiency programs that will reduce demands on the provincial grid. The government is also launching three new and enhanced programs for businesses, municipalities, and other institutions, including targeted support for greenhouse growers in Southwest Ontario.

“Our government is giving families more ways to lower their energy bills with new energy-efficiency programs like Peak Perks and ultra-low overnight rates available to consumers, which will provide families a $75 financial incentive this year in exchange for lowering their energy use at peak times during the summer,” said Todd Smith, Minister of Energy. “The new programs launched today will also help meet the province’s emerging electricity system needs by providing annual electricity savings equivalent to powering approximately 130,000 homes every year and, alongside electricity cost allocation discussions, reduce costs for consumers by over $650 million by 2025.”

The new Peak Perks program provides a financial incentive for residential customers who are willing to conserve energy and reduce their air conditioning at peak times and have an eligible smart thermostat connected to a central air conditioning system or heat pump unit. Participants will receive $75 for enrolling this year, as well as $20 for each year they stay enrolled in the program starting in 2024.

Residential customers can participate in Peak Perks by enrolling and giving their thermostat manufacturer secure access to their thermostat. Participants will be notified when one of the maximum 10 annual temperature change events occurs directly by their thermostat manufacturer on their mobile app and on their thermostat. Peak Perks has been designed to ensure participants are always in control and customers can opt-out of any temperature change event without impacting their incentive.

The Peak Perks program will be available starting in June. Interested customers can visit SaveOnEnergy.ca/PeakPerks today to sign-up for the program waitlist and receive an email notice with information on how to enroll.

In addition to the financial incentive provided by Peak Perks, reducing electricity use during peak demand hours in the summer months helps customers to lower their monthly electricity bills, and measures such as a temporary off-peak rate freeze have complemented these efforts, as these periods tend to be associated with the highest costs for power. Lowering demand during peak periods also allows the province to reduce electricity sector emissions, by reducing the need for electricity generation facilities that only run at times of peak demand such as natural gas.

Ontario has also launched three new and enhanced programs, including an expanded custom Retrofit program for business, municipalities and other institutions, and industrial electricity rate relief initiatives, targeted support for greenhouse growers in Southwest Ontario, as well enhancements to the existing Local Initiatives Program. The expanded Retrofit program alone will feature over $200 million in dedicated funding to support the new custom energy-efficiency retrofit project stream, that will cover up to 50 percent of the cost of approved projects.

These new and expanded energy-efficiency programs are expected to have a strong impact in Southwest Ontario, with regional peak demand savings of 225 megawatts (MW). This, together with the Ontario-Quebec energy swap agreement, will provide additional capacity for the region and support growing economic development. The overall savings from this energy-efficiency programming will result in an estimated three million tonnes of greenhouse gas emission reductions over its lifetime - the equivalent to taking more than 600,000 vehicles off the road for one year.

“Thanks to energy efficiency efforts over the past 15 years, demand for electricity is today about 12 per cent lower than it otherwise would be,” said Lesley Gallinger, President and CEO, of the Independent Electricity System Operator, Ontario’s grid operator and provider of Save on Energy programs to home and business consumers. “Conservation is a valuable and cost-effective resource that supports system reliability and helps drive economic development as we strive towards compliance with clean electricity regulations for a decarbonized electricity grid.”

Middle Tennessee Power Outages disrupt 100,000+ customers as severe thunderstorms, straight-line winds, downed trees, and debris challenge Nashville crews, slow restoration amid COVID-19, and threaten more hail, flash flooding, and damaging gusts.

Key Points

Blackouts across Nashville after severe storms and winds, leaving customers without power and facing restoration delays.

✅ Straight-line winds 60-80 mph toppled trees and power lines

✅ 130,000+ customers impacted; some outages may last 1-2 weeks

✅ Restoration slowed by debris, COVID-19 protocols, and new storms

Some middle Tennessee residents could be without electricity for up to two weeks after strong thunderstorms swept through the area Sunday, knocking out power for more than 100,000 customers, a scale comparable to Los Angeles outages after a station fire.

"Straight line winds as high as 60-80 miles per hour knocked down trees, power lines and power polls, interrupting power to 130,000 of our 400,000+ customers," Nashville Electric said in a statement Monday. The utility said the outage was one of the largest on record, though Carolina power outages recently left a quarter-million without power as well.

"Restoration times will depend on individual circumstances. In some cases, power could be out for a week or two" as challenges related to coronavirus and the need for utilities adapt to climate change complicated crews' responses and more storms were expected, the statement said. "This is unfortunate timing on the heels of a tornado and as we deal with battling COVID-19."

Metropolitan Nashville and Davidson County Mayor John Cooper also noted that the power outages were especially inconvenient, a challenge similar to Hong Kong families without power during Typhoon Mangkhut, as people were largely staying home to slow the spread of coronavirus. He also pointed out that the storms came on the two month anniversary of the Nashville tornado that left at least two dozen people dead.

"Crews are working diligently to restore power and clear any debris in neighborhoods," Cooper said.

He said that no fatalities were reported in the county but sent condolences to Spring Hill, whose police department reported that firefighter Mitchell Earwood died during the storm due to "a tragic weather-related incident" while at his home and off duty. He had served with the fire department for 10 years.

The Metro Nashville Department of Public Works said it received reports of more than 80 downed trees in Davidson County.

Officials also warn that copper theft can be deadly when electrical infrastructure is damaged after storms.

The National Weather Service Nashville said a 72 mph wind gust was measured at Nashville International Airport — the fifth fastest on record.

The weather service warned that strong storms with winds of up to 75 mph, large hail, record-long lightning bolt potential seen in the U.S., and isolated flash flooding could hit middle Tennessee again Monday afternoon and night.

"Treat Severe Thunderstorm Warnings the same way you would Tornado Warnings and review storm safety tips before you JUST TAKE SHELTER," the NWS instructs. "70 mph is 70 mph whether it's spinning around in a circle or blowing in a straight line."

Norway Electricity Export Limits weigh hydro reservoirs, energy security, EU-UK interconnectors, and record power prices amid Russia gas cuts; Statnett grid constraints and subsidies debate intensify as reservoir levels fall, threatening winter supply.

Key Points

Rules to curb Norway's power exports when reservoirs are very low, protecting supply security and easing extreme prices.

✅ Triggered by low hydro levels and record day-ahead prices

✅ Considers EU/UK cables, Statnett operations, seasonal thresholds

✅ Aims to secure winter supply and expand subsidies

Norway, one of Europe’s biggest electricity exporters, is considering measures to limit power shipments to prevent domestic shortages amid surging prices, according to local media reports.

The government may propose a rule to limit exports if the water level for Norway’s hydro reservoirs drops to “very low” levels, to ensure security of supply, said Energy Minister Terje Aasland, according NTB newswire. The limit would take account of seasonality and would differ across the about 1,800 hydro reservoirs, he said. 

Russia’s gas supply cuts in retaliation for European sanctions over the war in Ukraine have triggered the continent’s worst energy crisis in decades, with demand surging for cheap Norwegian hydro electricity. Yet the government faces increasing calls from the public and opposition to limit flows abroad. Prices are near record levels in some parts of the Nordic nation as hydro-reservoir levels have plunged in the south after a drier-than-normal spring. 

The government has been under pressure to do something about exports since before April. Flows on the cables are regulated by deals with both the European Union and the UK energy market and Norway can’t simply cut flows. It’s the latest test of European solidarity and a wake-up call for Europe when it comes to energy supplies. Hungary is trying to ban energy exports after it declared an energy emergency.

Back in May, grid operator Statnett SF warned that Norway could face a strained power situation after less snowfall than usual during the winter. At the end of last week, the level of filling in Norwegian hydro reservoirs was 66.5%, compared with a median 74.9% for the corresponding time in 2002-2021, regulator NVE said. Day-ahead electricity prices in southwest Norway soared to a record 423 euros per megawatt-hour late last month, partly due to bottlenecks in the grid limiting supply from the northern regions.

The grid operator has been asked to present by Oct. 1 possible measures that need to be taken to secure supply and infrastructure security ahead of the winter. Statnett operates cables to the UK and Germany aimed at selling surplus electricity and would likely take a financial hit if curbs were introduced. “Operations of these will always follow current laws and regulations,” Irene Meldal, a company spokeswoman, said Friday by email. 

Premier Jonas Gahr Store signaled his minority government will file proposals that also include more subsidies to families and companies and align with Europe’s emergency price measures during August, according to an interview with TV2 on Thursday. Meanwhile, opposition politicians plan to hold an extraordinary parliament meeting to discuss boosting the subsidies.

Aasland will summon the parties’ representatives to a meeting on Monday on the electricity crisis, the Aftenposten newspaper reported on Friday, without citing anyone. He intends to inform the parties about the ongoing work and aims to “avoid rushed decisions” by the parliamentary majority.

Norway Faces Pressure to Curb Power Exports as Prices Surge (1)

The nation gets almost all of its electricity from its vast hydro resources. Historically, it has been able to export a hefty surplus and still have among the lowest prices in Europe.

Bitcoin Energy Consumption drives debate on blockchain mining, proof-of-work, carbon footprint, and emissions, with CCAF estimates in terawatt hours highlighting electricity demand, fossil fuel reliance, and sustainability concerns for data centers and cryptocurrency networks.

Key Points

Electricity used by Bitcoin proof-of-work mining, often fossil-fueled, estimated by CCAF in terawatt hours.

✅ CCAF: 40-445 TWh, central estimate ~130 TWh

✅ ~66% of mining electricity sourced from fossil fuels

✅ Proof-of-work increases hash rate, energy, and emissions

The University of Cambridge Centre for Alternative Finance (CCAF) studies the burgeoning business of cryptocurrencies.

It calculates that Bitcoin's total energy consumption is somewhere between 40 and 445 annualised terawatt hours (TWh), with a central estimate of about 130 terawatt hours.

The UK's electricity consumption is a little over 300 TWh a year, while Argentina uses around the same amount of power as the CCAF's best guess for Bitcoin, as countries like New Zealand's electricity future are debated to balance demand.

And the electricity the Bitcoin miners use overwhelmingly comes from polluting sources, with the U.S. grid not 100% renewable underscoring broader energy mix challenges worldwide.

The CCAF team surveys the people who manage the Bitcoin network around the world on their energy use and found that about two-thirds of it is from fossil fuels, and some regions are weighing curbs like Russia's proposed mining ban amid electricity deficits.

Huge computing power - and therefore energy use - is built into the way the blockchain technology that underpins the cryptocurrency has been designed.

It relies on a vast decentralised network of computers.

These are the so-called Bitcoin "miners" who enable new Bitcoins to be created, but also independently verify and record every transaction made in the currency.

In fact, the Bitcoins are the reward miners get for maintaining this record accurately.

It works like a lottery that runs every 10 minutes, explains Gina Pieters, an economics professor at the University of Chicago and a research fellow with the CCAF team.

Data processing centres around the world, including hotspots such as Iceland's mining strain, race to compile and submit this record of transactions in a way that is acceptable to the system.

They also have to guess a random number.

The first to submit the record and the correct number wins the prize - this becomes the next block in the blockchain.

Estimates for bitcoin's electricity consumption
At the moment, they are rewarded with six-and-a-quarter Bitcoins, valued at about $50,000 each.

As soon as one lottery is over, a new number is generated, and the whole process starts again.

The higher the price, says Prof Pieters, the more miners want to get into the game, and utilities like BC Hydro suspending new crypto connections highlight grid pressures.

"They want to get that revenue," she tells me, "and that's what's going to encourage them to introduce more and more powerful machines in order to guess this random number, and therefore you will see an increase in energy consumption," she says.

And there is another factor that drives Bitcoin's increasing energy consumption.

The software ensures it always takes 10 minutes for the puzzle to be solved, so if the number of miners is increasing, the puzzle gets harder and the more computing power needs to be thrown at it.

Bitcoin is therefore actually designed to encourage increased computing effort.

The idea is that the more computers that compete to maintain the blockchain, the safer it becomes, because anyone who might want to try and undermine the currency must control and operate at least as much computing power as the rest of the miners put together.

What this means is that, as Bitcoin gets more valuable, the computing effort expended on creating and maintaining it - and therefore the energy consumed - inevitably increases.

We can track how much effort miners are making to create the currency.

They are currently reckoned to be making 160 quintillion calculations every second - that's 160,000,000,000,000,000,000, in case you were wondering.

And this vast computational effort is the cryptocurrency's Achilles heel, says Alex de Vries, the founder of the Digiconomist website and an expert on Bitcoin.

All the millions of trillions of calculations it takes to keep the system running aren't really doing any useful work.

"They're computations that serve no other purpose," says de Vries, "they're just immediately discarded again. Right now we're using a whole lot of energy to produce those calculations, but also the majority of that is sourced from fossil energy, and clean energy's 'dirty secret' complicates substitution."

The vast effort it requires also makes Bitcoin inherently difficult to scale, he argues.

"If Bitcoin were to be adopted as a global reserve currency," he speculates, "the Bitcoin price will probably be in the millions, and those miners will have more money than the entire [US] Federal budget to spend on electricity."

"We'd have to double our global energy production," he says with a laugh, even as some argue cheap abundant electricity is getting closer to reality today. "For Bitcoin."

He says it also limits the number of transactions the system can process to about five per second.

This doesn't make for a useful currency, he argues.

And that view is echoed by many eminent figures in finance and economics.

The two essential features of a successful currency are that it is an effective form of exchange and a stable store of value, says Ken Rogoff, a professor of economics at Harvard University in Cambridge, Massachusetts, and a former chief economist at the International Monetary Fund (IMF).

He says Bitcoin is neither.

"The fact is, it's not really used much in the legal economy now. Yes, one rich person sells it to another, but that's not a final use. And without that it really doesn't have a long-term future."

What he is saying is that Bitcoin exists almost exclusively as a vehicle for speculation.

So, I want to know: is the bubble about to burst?

"That's my guess," says Prof Rogoff and pauses.

"But I really couldn't tell you when."
