Progress Energy has once again delayed restarting its Crystal River nuclear power plant north of Tampa Bay after discovering new cracks in the reactor building.

The good news is the company says the cracks are not a threat to public safety, despite the unfortunate timing of announcing the need for more repairs amid growing international concern over Japan's nuclear power plant crisis.

The bad news is Progress Energy has announced plans several times over the past 18 months to restart the Crystal River plant, located in Citrus County. But the company has been forced to postpone those startups due to concerns over the integrity of the 42-inch concrete wall surrounding the nuclear reactor. The price tag in extra costs due to the long delay is approaching half a billion dollars.

The facility, Progress Energy's sole nuclear power plant in Florida, was taken offline in September 2009 for refueling and maintenance. A crack or "delamination" discovered in the concrete wall surrounding the reactor was repaired. The plant was expected to begin operation next month once steel tension bands or "tendons" in the wall were carefully tightened to provide added strength to the containment building.

The containment building houses the plant's nuclear reactor, steam generators and other pumps and valves. The electrical generators are in another building. The structure is engineered to contain the rapid buildup of heat and pressure that would take place if a large pipe broke.

Signs of new cracks were found as a result of that retensioning process. No new startup date has been set.

"There are indications of additional delamination or separation resulting from the repair work," Progress Energy stated. "Engineers are evaluating the situation and will conduct a thorough assessment of repair options and the impact to the plant's restart plans."

"This has been a first-of-a-kind repair, and we will continue to move forward cautiously and deliberately," Progress Energy Florida CEO Vincent Dolan said in a statement.

The Crystal River nuclear plant began operating in 1977. Progress Energy wants to extend its operation another 20 years beyond 2016, the original lifespan of the plant's 40-year license.

Broken down, Progress Energy spent $150 million for repairs as of December and another $290 million to buy the electricity that otherwise would have been generated by the plant.

Part of those costs are covered by Progress Energy's insurance company, Nuclear Electric Insurance Limited. As of December, it had paid out $181 million to the utility. Of that, $117 million went toward buying replacement power and $64 million for repairs. Ongoing costs will raise the final price tag.

Progress continues to submit claims to its insurance company. The amount the insurance company doesn't pay will be passed on to its 1.6 million Florida customers.

Electric vehicles are a hot topic in southern Alberta

Canada Electric Vehicle Adoption is accelerating as EV range doubles, fast-charging networks expand along the Trans-Canada Highway, and drivers shift from internal combustion to clean transportation to cut emissions and support climate goals.

 

Key Points

Canada Electric Vehicle Adoption reflects rising EV uptake, longer range, and expanding fast-charging infrastructure.

✅ Average EV range in Canada has nearly doubled in six years.

✅ Fast chargers expanding along Trans-Canada and major corridors.

✅ Gasoline and diesel demand projected to fall sharply by 2040.

 

As green technology for vehicles continues to grow in popularity, with a recent EV event in Regina drawing strong interest, attendance at a seminar in southern Alberta Wednesday showed plenty people want to switch to electric.

FreeU, a series of informal education sessions about electric power and climate change, including electricity vs hydrogen considerations, helped participants to learn more about the world-changing technology.

Also included at the talks was a special electric vehicle meet up, where people interested in the technology could learn about it, first hand, from drivers who've already gone gasless despite EV shortages and wait times in many regions.

"That's kind of a warning or a caution or whatever you want to call it. You get addicted to these things and that's a good example."

James Byrne, a professor of geography at the University of Lethbridge says people are much more willing these days to look to alternatives for their driving needs, though cost remains a key barrier for many.

"The internal combustion engine is on its way out. It served us well, but electric vehicles are much cleaner, aligning with Canada's EV goals set by policymakers today."

According to the Canada Energy Regulator, the average range of electric vehicles in Canada have almost doubled in the past six years.

The agency also predicts a massive decrease in gasoline and diesel use (359 petajoules and 92 petajoules respectively) in Canada by 2040. In that same timeframe, electricity use, even though fossil-fuel share remains, is expected to increase by 118 petajoules.

The country is also developing its network of fast charging stations, so running out of juice will be less of a worry for prospective buyers, even as 2035 EV mandate debate continues among analysts.

"They have just about Interstate in the U.S. covered," Marshall said. "In Canada, they're building out the [Trans-Canada Highway] right now."

US NRC streamlines licensing for advanced reactors

NRC Advanced Reactor Licensing streamlines a risk-informed, performance-based, technology-inclusive pathway for advanced non-light water reactors, aligning with NEIMA to enable predictable regulatory reviews, inherent safety, clean energy deployment, and industrial heat, hydrogen, and desalination applications.

 

Key Points

A risk-informed, performance-based NRC pathway streamlining licensing for advanced non-light water reactors.

✅ Aligned with NEIMA: risk-informed, performance-based, tech-inclusive

✅ Predictable licensing for advanced non-light water reactor designs

✅ Enables clean heat, hydrogen, desalination beyond electricity

 

The US Nuclear Regulatory Commission (NRC) voted 4-0 to approve the implementation of a more streamlined and predictable licensing pathway for advanced non-light water reactors, aligning with nuclear innovation priorities identified by industry advocates, the Nuclear Energy Institute (NEI) announced, and amid regional reliability measures such as New England emergency fuel stock plans that have drawn cost scrutiny.

This approach is consistent with the Nuclear Energy Innovation and Modernisation Act (NEIMA), a nuclear innovation act passed in 2019 by the US Congress calling for the development of a risk-informed, performance-based and technology inclusive licensing process for advanced reactor developers.

NEI Chief Nuclear Officer Doug True said: “A modernised regulatory framework is a key enabler of next-generation nuclear technologies that, amid ACORE’s challenge to DOE subsidy proposals in energy market proceedings, can help us meet our energy needs while protecting the climate. The Commission’s unanimous approval of a risk-informed and performance-based licensing framework paves the way for regulatory reviews to be aligned with the inherent safety characteristics, smaller reactor cores and simplified designs of advanced reactors.”

Over the last several years the industry’s Licensing Modernisation Project, sponsored by US Department of Energy, led by Southern Nuclear, and supported by NEI’s Advanced Reactor Regulatory Task Force, and influenced by a presidential order to bolster uranium and nuclear energy, developed the guidance for this new framework. Amid shifts in the fuel supply chain, including the U.S. ban on Russian uranium, this approach will inform the development of a new rule for licensing advanced reactors, which NEIMA requires.

“A well-defined licensing path will benefit the next generation of nuclear plants, especially as regions consider New England market overhaul efforts, which could meet a wide range of applications beyond generating electricity such as producing heat for industry, desalinating water, and making hydrogen – all without carbon emissions,” True noted.

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.

Electricity Regulation With Equity & Justice For All

Energy equity in utility regulation prioritizes fair rates, clean energy access, and DERs, addressing fixed charges and energy burdens on low-income households through stakeholder engagement and public utility commission reforms.

 

Key Points

Fairly allocates clean energy benefits and rate burdens, ensuring access and protections for low-income households.

✅ Reduces fixed charges that burden low-income households

✅ Funds community participation in utility proceedings

✅ Prioritizes DERs, energy efficiency, and solar in impacted areas

 

By Kiran Julin

Pouring over the line items on your monthly electricity bill may not sound like an enticing way to spend an afternoon, but the way electricity bills are structured has a significant impact on equitable energy access and distribution. For example, fixed fees can have a disproportionate impact on low-income households. And combined with other factors, low-income households and households of color are far more likely to report losing home heating service, with evidence from pandemic power shut-offs highlighting these disparities, according to recent federal data.

Advancing Equity in Utility Regulation, a new report published by the U.S. Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory (Berkeley Lab), makes a unifying case that utilities, regulators, and stakeholders need to prioritize energy equity in the deployment of clean energy technologies and resources, aligning with a people-and-planet electricity future envisioned by advocacy groups. Equity in this context is the fair distribution of the benefits and burdens of energy production and consumption. The report outlines systemic changes needed to advance equity in electric utility regulation by providing perspectives from four organizations — Portland General Electric, a utility company; the National Consumer Law Center, a consumer advocacy organization; and the Partnership for Southern Equity and the Center for Biological Diversity, social justice and environmental organizations.
 
“While government and ratepayer-funded energy efficiency programs have made strides towards equity by enabling low-income households to access energy-efficiency measures, that has not yet extended in a major way to other clean-energy technologies,” said Lisa Schwartz, a manager and strategic advisor at Berkeley Lab and technical editor of the report. “States and utilities can take the lead to make sure the clean-energy transition does not leave behind low-income households and communities of color. Decarbonization and energy equity goals are not mutually exclusive, and in fact, they need to go hand-in-hand.”

Energy bills and electricity rates are governed by state laws and utility regulators, whose mission is to ensure that utility services are reliable, safe, and fairly priced. Public utility commissions also are increasingly recognizing equity as an important goal, tool, and metric, and some customers face major changes to electric bills as reforms advance. While states can use existing authorities to advance equity in their decision-making, several, including Illinois, Maine, Oregon, and Washington, have enacted legislation over the last couple of years to more explicitly require utility regulators to consider equity.

“The infrastructure investments that utility companies make today, and regulator decisions about what goes into electricity bills, including new rate design steps that shape customer costs, will have significant impacts for decades to come,” Schwartz said.

Solutions recommended in the report include considering energy justice goals when determining the “public interest” in regulatory decisions, allocating funding for energy justice organizations to participate in utility proceedings, supporting utility programs that increase deployment of energy efficiency and solar for low-income households, and accounting for energy inequities and access in designing electricity rates, while examining future utility revenue models as technologies evolve.

The report is part of the Future of Electric Utility Regulation series that started in 2015, led by Berkeley Lab and funded by DOE, to encourage informed discussion and debate on utility trends and tackling the toughest issues related to state electric utility regulation. An advisory group of utilities, public utility commissioners, consumer advocates, environmental and social justice organizations, and other experts provides guidance.

 

Taking stock of past and current energy inequities

One focus of the report is electricity bills. In addition to charges based on usage, electricity bills usually also have a fixed basic customer charge, which is the minimum amount a household has to pay every month to access electricity. The fixed charge varies widely, from $5 to more than $20. In recent years, utility companies have sought sizable increases in this charge to cover more costs, amid rising electricity prices in some markets.

This fixed charge means that no matter what a household does to use energy more efficiently or to conserve energy, there is always a minimum cost. Moreover, low-income households often live in older, poorly insulated housing. Current levels of public and utility funding for energy-efficiency programs fall far short of the need. The combined result is that the energy burden – or percent of income needed to keep the lights on and their homes at a healthy temperature – is far greater for lower-income households.

“While all households require basic lighting, heating, cooling, and refrigeration, low-income households must devote a greater proportion of income to maintain basic service,” explained John Howat and Jenifer Bosco from the National Consumer Law Center and co-authors of Berkeley Lab’s report. Their analysis of data from the most recent U.S. Energy Information Administration’s Residential Energy Consumption Survey shows households with income less than $20,000 reported losing home heating service at a pace more than five times higher than households with income over $80,000. Households of color were far more likely than those with a white householder to report loss of heating service. In addition, low-income households and households of color are more likely to have to choose between paying their energy bill or paying for other necessities, such as healthcare or food.

Based on the most recent data (2015) from the U.S. Energy Information Administration (EIA), households with income less than $20,000 reported losing home heating service at a rate more than five times higher than households with income over $80,000. Households of color were far more likely than those with a white householder to report loss of heating service. Click on chart for larger view.

Moreover, while many of the infrastructure investment decisions that utilities make, such as whether and where to build a new power plant, often have long-term environmental and health consequences, impacted communities often are not at the table. “Despite bearing an inequitable proportion of the negative impacts of environmental injustices related to fossil fuel-based energy production and climate change, marginalized communities remain virtually unrepresented in the energy planning and decision-making processes that drive energy production, distribution, and regulation,” wrote Chandra Farley, CEO of ReSolve and a co-author of the report.


Engaging impacted communities
Each of the perspectives in the report identify a need for meaningful engagement of underrepresented and disadvantaged communities in energy planning and utility decision-making. “Connecting the dots between energy, racial injustice, economic disinvestment, health disparities, and other associated equity challenges becomes a clarion call for communities that are being completely left out of the clean energy economy,” wrote Farley, who previously served as the Just Energy Director at Partnership for Southern Equity. “We must prioritize the voices and lived experiences of residents if we are to have more equity in utility regulation and equitably transform the energy sector.”

In another essay in the report, Nidhi Thaker and Jake Wise from Portland General Electric identify the importance of collaborating directly with the communities they serve. In 2021, the Oregon Legislature passed Oregon HB 2475, which allows the Oregon Public Utility Commission to allocate ratepayer funding for organizations representing people most affected by a high energy burden, enabling them to participate in utility regulatory processes.

The report explains why energy equity requires correcting inequities resulting from past and present failures as well as rethinking how we achieve future energy and decarbonization goals. “Equity in energy requires adopting an expansive definition of the ‘public interest’ that encompasses energy, climate, and environmental justice. Energy equity also means prioritizing the deployment of distributed energy resources and clean energy technologies in areas that have been hit first and worst by the existing fossil fuel economy,” wrote Jean Su, energy justice director and senior attorney at the Center for Biological Diversity.

This report was supported by DOE’s Grid Modernization Laboratory Consortium, with funding from the Office of Energy Efficiency and Renewable Energy and the Office of Electricity.

N.B. Power hits pause on large new electricity customers during crypto review

N.B. Power Crypto Mining Moratorium underscores electricity demand risks from bitcoin mining, straining the energy grid and industrial load capacity in New Brunswick, as a cabinet order prioritizes grid reliability, utility planning, and allocation.

 

Key Points

Official pause on new large-scale crypto mining to protect N.B. Power grid capacity, stability, and reliable supply.

✅ Cabinet order halts new large-scale crypto load requests

✅ Review targets grid reliability, planning, and capacity

✅ Non-crypto industrial customers exempt from prolonged pause

 

N.B. Power says a freeze on servicing new, large-scale industrial customers in the province remains in place over concerns that the cryptocurrency sector's heavy electricity use could be more than the utility can handle.

The Higgs government quietly endorsed the moratorium in a cabinet order in March 2022 and ordered a review of how the sector might affect the reliable electricity supply and broader electricity future planning in the province.

The cabinet order, filed with the Energy and Utilities Board, said N.B. Power had "policy, technical and operational concerns about [its] capacity to service the anticipated additional load demand" from energy-intensive customers such as crypto mines.

It said the utility had received "several new large-scale, short-notice service requests" to supply electricity to crypto mining companies that could put "significant pressure" on the existing electricity supply.

The order, signed by Premier Blaine Higgs, said non-crypto companies shouldn't be subject to the pause for any longer than required for the review, amid shifts in regional plans like the Atlantic Loop that are altering timelines. Ws.

The freeze was ordered months after Taal Distributed Information Technologies Inc. announced plans to establish a 50-megawatt bitcoin mining operation and transaction processing facility in Grand Falls.

A town official said this week that the deal never went ahead.

24 hours a day
The Taal facility would have joined a 70-megawatt bitcoin mine in Grand Falls operated by Hive Blockchain Technologies.

Hive's Bitcoin mine comprises four large warehouses containing thousands of computers running 24 hours a day to earn cryptocurrency units.

The combined annual electricity consumption of the two mines would exceed what could be produced by the small modular nuclear reactor being designed by ARC Clean Energy Canada of Saint John, even as Nova Scotia advances efforts to harness the Bay of Fundy's powerful tides for clean power.

Put another way, the two mines would gobble up more than three months' electricity from N.B. Power's coal-fired Belledune generating station under current operations.

Growing pot sucks up electricity and pumps out an astounding amount of carbon dioxide — it doesn't have to

Sustainable Cannabis Cultivation leverages greenhouse design, renewable energy, automation, and water recapture to cut electricity use, emissions, and pesticides, delivering premium yields with natural light, smart sensors, and efficient HVAC and irrigation control.

 

Key Points

A data-driven, low-impact method that cuts energy, water, and chemicals while preserving premium yields.

✅ 70-90% less electricity vs. conventional indoor grows

✅ Natural light, solar, and rainwater recapture reduce footprint

✅ Automation, sensors, and HVAC stabilize microclimates

 

In the seven months since the Trudeau government legalized recreational marijuana use, licensed producers across the country have been locked in a frenetic race to grow mass quantities of cannabis for the new market.

But amid the rush for scale, questions of sustainability have often taken a back seat, and in Canada, solar adoption has lagged in key sectors.

According to EQ Research LLC, a U.S.-based clean-energy consulting firm, cannabis facilities can need up to 150 kilowatt-hours of electricity per year per square foot. Such input is on par with data centres, which are themselves 50 to 200 times more energy-intensive than a typical office building, and achieving zero-emission electricity by 2035 would help mitigate the associated footprint.

At the Lawrence Berkley National Laboratory in California, a senior scientist estimated that one per cent of U.S. electricity use came from grow ops. The same research — published in 2012 — also found that the procedures for refining a kilogram of weed emit around 4,600 kilograms of carbon dioxide to the atmosphere, equivalent to operating three million cars for a year, though a shift to zero-emissions electricity by 2035 could substantially cut those emissions.

“All factors considered, a very large expenditure of energy and consequent ‘environmental imprint’ is associated with the indoor cultivation of marijuana,” wrote Ernie Small, a principal research scientist for Agriculture and Agri-Food Canada, in the 2018 edition of the Biodiversity Journal.

Those issues have left some turning to technology to try to reduce the industry’s footprint — and the economic costs that come with it — even as more energy sources make better projects for forward-looking developers.

“The core drawback of most greenhouse environments is that you’re just getting large rooms, which are harder to control,” says Dan Sutton, the chief executive officer of Tantalus Labs., a B.C.-based cannabis producer. “What we did was build a system specifically for cannabis.”

Sutton is referring to SunLab, the culmination of four years of construction, and at present the main site where his company nurtures rows of the flowering plant. The 120,000-square foot structure was engineered for one purpose: to prove the merits of a sustainable approach.

“We’re actually taking time-series data on 30 different environmental parameters — really simple ones like temperature and humidity — all the way down to pH of the soil and water flow,” says Sutton. “So if the temperature gets a little too cold, the system recognizes that and kicks on heaters, and if the system senses that the environment is too hot in the summertime, then it automatically vents.”

A lot is achieved without requiring much human intervention, he adds. Unlike conventional indoor operations, SunLab demands up to 90 per cent less electricity, avoids using pesticides, and draws from natural light and recaptured rainwater to feed its crops.

The liquid passes through a triple-filtration process before it is pumped into drip irrigation tubing. “That allows us to deliver a purity of water input that is cleaner than bottled water,” says Sutton.

As transpiration occurs, a state-of-the-art, high-capacity airflow suspended below the ceiling cycles air at seven-minute intervals, repeatedly cooling the air and preventing outbreaks of mould, while genetically modified “guardian” insects swoop in to eliminate predatory pests.

“When we first started, people never believed we would cultivate premium quality cannabis or cannabis that belongs on the top shelf, shoulder to shoulder with the best in the world and the best of indoor,” says Sutton.

Challenges still exist, but they pale in comparison to the obstacles that American companies with an interest in adopting greener solutions persistently face, and in provinces like Alberta, an Alberta renewable energy surge is reshaping the opportunity set.

Although cannabis is legal in a number of states, it remains illegal federally, which means access to capital and regulatory clarity south of the border can be difficult to come by.

“Right now getting a new project built is expensive to do because you can’t get traditional bank loans,” says Canndescent CEO Adrian Sedlin, speaking by phone from California.

In retrofitting the company’s farm to accommodate a sizeable solar field, he struggled to secure investors, even as a solar-powered cannabis facility in Edmonton showcased similar potential.

“We spent over a year and a half trying to get it financed,” says Sedlin. “Finding someone was the hard part.”

Decriminalizing the drug would ultimately increase the supply of capital and lower the costs for innovative designs, something Sedlin says would help incentivize producers to switch to more effective and ecologically sound techniques.

Some analysts argue that selling renewable energy in Alberta could become a major growth avenue that benefits energy-intensive industries like cannabis cultivation.

Canndescent, however, is already there.

“We’re now harnessing the sun to reduce our reliance on fossil fuels and going to sustainable, or replenishable, energy sources, while leveraging the best and most efficient water practices,” says Sedlin. “It’s the right thing to do.”
