For the second time since Dominion purchased Millstone Power Station in 2001, the company is considering boosting power at the Unit 3 reactor.

"We are investigating the feasibility of an uprate at Unit 3," Ken Holt, a Dominion spokesman, said. "We have not made a definitive decision. We are in the study phase right now."

Two years ago, the Nuclear Regulatory Commission approved a 7-percent "stretch power uprate" at Unit 3, the newer of the two operating reactors there. The uprate increased the amount of electricity generated at Unit 3 by 80 megawatts, bumping up overall output from approximately 1,150 to 1,227 megawatts, enough to power about 60,000 additional homes.

An uprate is an increase in the maximum power level at which a commercial nuclear power plant may operate, according to the NRC website. The reactor owner is only allowed to adjust that output if it demonstrates to the NRC that the plant can continue to operate safely with the uprate in place.

Today, Units 2 and Unit 3, combined, produce 2,111 megawatts of electricity, enough to power about 1 million homes.

Dominion started its latest uprate analysis about a year ago, and doesn't believe it will be done with the assessment "anytime soon," Holt said. Dominion will finish the study and make a decision "when we are satisfied our reviews are complete and we have done a thorough job evaluating it," he said.

The company also went to ISO New England, the manager of the region's electric grid, late last year to find out if there is any availability on the grid to take more electricity from Millstone, he added.

An ISO New England spokeswoman said she cannot confirm the status of any request or proposal from any specific party.

Holt said he could not discuss the amount of any possible increase in megawatts from a second uprate unless and until the company actually applied for it.

The Unit 2 reactor generates about 884 megawatts, according to recent filings with the Connecticut Siting Council, which is in the process of writing its annual forecast on electric loads and resources.

A third reactor at Millstone, Unit 1, is closed.

Report call for major changes to operation of Nova Scotia's power grid

Nova Scotia Energy Modernization Act proposes an independent system operator, focused energy regulation, coal phase-out by 2030, renewable integration, transmission upgrades, and competitive market access to boost consumer trust and grid reliability across the province.

 

Key Points

Legislation to create an independent system operator and energy regulator, enabling coal phase-out and renewable integration.

✅ Transfers grid control from Nova Scotia Power to an ISO

✅ Establishes a focused energy regulator for multi-sector oversight

✅ Accelerates coal retirement, renewables build-out, and grid upgrades

 

Nova Scotia is poised for a significant overhaul in how its electricity grid operates, with the electricity market headed for a reshuffle as the province vows changes, following a government announcement that will strip the current electric utility of its grid access control. This move is part of a broader initiative to help the province achieve its ambitious energy objectives, including the cessation of coal usage by 2030.

The announcement came from Tory Rushton, the Minister of Natural Resources, who highlighted the recommendations from the Clean Electricity Task Force's report to make the electricity system more accountable to Nova Scotians according to the authors. The report suggests the creation of two distinct entities: an autonomous system operator for energy system planning and an independent body for energy regulation.

Minister Rushton expressed the government's agreement with these recommendations, while the premier had earlier urged regulators to reject a 14% rate hike to protect customers, stating plans to introduce a new Energy Modernization Act in the next legislative session.

Under the proposed changes, Nova Scotia Power, a privately-owned entity, will retain its operational role but will relinquish control over the electricity grid. This responsibility will shift to an independent system operator, aiming to foster competitive practices essential for phasing out coal—currently a major source of the province’s electricity.

Additionally, the existing Utility and Review Board, which recently approved a 14% rate increase despite political opposition, will undergo rebranding to become the Nova Scotia Regulatory and Appeals Board, reflecting a broader mandate beyond energy. Its electricity-related duties will be transferred to the newly proposed Nova Scotia Energy Board, which will oversee various energy sectors including electricity, natural gas, and retail gasoline.

The task force, led by Alison Scott, a former deputy energy minister, and John MacIsaac, an ex-executive of Nalcor Energy, was established by the province in April 2023 to determine the needs of the electrical system in meeting Nova Scotia's environmental goals.

Minister Rushton praised the report for providing a clear direction towards achieving the province's 2030 environmental targets and beyond. He estimated that establishing the recommended bodies would take 18 months to two years, and noted the government cannot order the utility to cut rates under current law, promising job security for current employees of Nova Scotia Power and the Utility and Review Board throughout the transition.

The report advocates for the new system operator to improve consumer trust by distancing electricity system decisions from Nova Scotia Power's corporate interests. It also critiques the current breadth of the Utility and Review Board's mandate as overly extensive for addressing the energy transition's long-term requirements.

Nova Scotia Power's president, Peter Gregg, welcomed the recommendations, emphasizing their role in the province's shift towards renewable energy, as neighboring jurisdictions like P.E.I. explore community generation to build resilience, he highlighted the importance of a focused energy regulator and a dedicated system operator in advancing essential projects for reliable customer service.

The task force's 12 recommendations also include the requirement for Nova Scotia Power to submit an annual asset management plan for regulatory approval and to produce reports on vegetation and wood pole management. It suggests the government assess Ontario's hydro policies for potential adaptation in Nova Scotia and calls for upgrades to the transmission grid infrastructure, with projected costs detailed by Stantec.

Alison Scott remarked on the comparative expense of coal power against renewable sources like wind, suggesting that investments in the grid to support renewables would be economically beneficial in the long run.

Experiment Shows We Can Actually Generate Electricity From The Night Sky

Nighttime thermoradiative power converts outgoing infrared radiation into electricity using semiconductor photodiodes, leveraging negative illumination and sky cooling to harvest renewable energy from Earth-to-space heat flow when solar panels rest, regardless of weather.

 

Key Points

Nighttime thermoradiative power converts Earth's outgoing infrared heat into electricity using semiconductor diodes.

✅ Uses negative illumination to tap Earth-to-space heat flow

✅ Infrared semiconductor photodiodes generate small nighttime current

✅ Theoretical output ~4 W/m^2; lab demo reached 64 nW/m^2

 

There's a stark contrast between the freezing temperatures of space and the relatively balmy atmosphere of Earth, and that contrast could help generate electricity, scientists say – and alongside concepts such as space-based solar power, utilizing the same optoelectronic physics used in solar panels. The obvious difference this would have compared with solar energy is that it would work during the night time, a potential source of renewable power that could keep on going round the clock and regardless of weather conditions.

Solar panels are basically large-scale photodiodes - devices made out of a semiconducting material that converts the photons (light particles) coming from the Sun into electricity by exciting electrons in a material such as silicon, while concepts like space solar beaming could complement them during adverse weather.

In this experiment, the photodiodes work 'backwards': as photons in the form of infrared radiation - also known as heat radiation - leave the system, a small amount of energy is produced, similar to how raindrop electricity harvesting taps ambient fluxes in other experiments.

This way, the experimental system takes advantage of what researchers call the "negative illumination effect" – that is, the flow of outgoing radiation as heat escapes from Earth back into space. The setup explained in the new study uses an infrared semiconductor facing into the sky to convert this flow into electrical current.

"The vastness of the Universe is a thermodynamic resource," says one of the researchers, Shanhui Fan from Stanford University in California.

"In terms of optoelectronic physics, there is really this very beautiful symmetry between harvesting incoming radiation and harvesting outgoing radiation."

It's an interesting follow-up to a research project Fan participated in last year: a solar panel that can capture sunlight while also allowing excess heat in the form of infrared radiation to escape into space.

In the new study, this "energy harvesting from the sky" process can produce a measurable amount of electricity, the researchers have shown – though for the time being it's a long way from being efficient enough to contribute to our power grids, but advances in peer-to-peer energy sharing could still make niche deployments valuable.

In the team's experiments they were able to produce 64 nanowatts per square metre (10.8 square feet) of power – only a trickle, but an amazing proof of concept nevertheless. In theory, the right materials and conditions could produce a million times more than that, and analyses of cheap abundant electricity show how rapidly such advances compound, reaching about 4 watts per square metre.

"The amount of power that we can generate with this experiment, at the moment, is far below what the theoretical limit is," says one of the team, Masashi Ono from Stanford.

When you consider today's solar panels are able to generate up to 100-200 watts per square metre, and in China solar is cheaper than grid power across every city, this is obviously a long way behind. Even in its earliest form, though, it could be helpful for keeping low-power devices and machines running at night: not every renewable energy device needs to power up a city.

Now that the researchers have proved this can work, the challenge is to improve the performance of the experimental device. If it continues to show promise, the same idea could be applied to capture energy from waste heat given off by machinery, and results in humidity-powered generation suggest ambient sources are plentiful.

"Such a demonstration of direct power generation of a diode facing the sky has not been previously reported," explain the researchers in their published paper.

"Our results point to a pathway for energy harvesting during the night time directly using the coldness of outer space."

The research has been published in Applied Physics Letters.

B.C. politicians must focus more on phasing out fossil fuels, report says

BC Fossil Fuel Phase-Out outlines a just transition to a green economy, meeting climate targets by mid-century through carbon budgets, ending subsidies for fracking, capping production, and investing in renewable energy, remediation, and resilient infrastructure.

 

Key Points

A strategic plan to wind down oil and gas, end subsidies, and achieve climate targets with a just transition in BC.

✅ End new leases, phase out subsidies, cap fossil production

✅ Carbon budgets and timelines to meet mid-century climate targets

✅ Just transition: income supports, retraining, site remediation jobs

 

Politicians in British Columbia aren't focused enough on phasing out fossil fuel industries, a new report says.

The report, authored by the left-leaning Canadian Centre for Policy Alternatives, says the province must move away from fossil fuel industries by mid-century in order to meet its climate targets, with B.C. projected to fall short of 2050 targets according to recent analysis, but adds that the B.C. government is ill prepared to transition to a green economy.

"We are totally moving in the wrong direction," said economist Marc Lee, one of the authors of the report, on The Early Edition Wednesday. 

He said most of the emphasis of B.C. government policy has been on slowing reductions in emissions from transportation or emissions from buildings, even though Canada will need more electricity to hit net-zero according to the IEA, while still subsidizing fossil fuel extraction, such as fracking projects, that Lee said should be phased out.

"What we are putting on the table is politically unthinkable right now," said Lee, adding that last month's provincial budget called for a 26 per cent increased gas production over the next three years, even though electrified LNG facilities could boost demand for clean power.

B.C.'s $830M in fossil fuel subsidies undermines efforts to fight climate crisis, report says
He said B.C. needs to start thinking instead about how its going to wind down its dependence on fossil fuel industries.

 

'Greener' job transition needed
The report said the provincial government's continued interest in expanding production and exporting fossil fuels, even as Canada's race to net-zero intensifies across the energy sector, suggests little political will to think about a plan to move away from them.

It suggests the threat of major job losses in those industries is contributing to the political inaction, but cited several examples of ways governments can help move workers into greener jobs, as many fossil-fuel workers are ready to support the transition according to recent commentary. 

Lee said early retirement provisions or income replacement for transitioning workers are options to consider.

"We actually have seen a lot of real-world policy around transition starting to happen, including in Alberta, which brought in a whole transition package for coal workers producing coal for electricity generation, and regional cooperation like bridging the electricity gap between Alberta and B.C. could further support reliability," Lee said.

Give cities the power to move more quickly on the environment, say Metro Van politicians
Make it easier for small businesses to go green, B.C. Chamber of Commerce urges government
Lee also said well-paying jobs could be created by, for example, remediating old coal mines and gas wells and building green infrastructure and renewable electricity projects in affected areas.

The report also calls for a moratorium on new fossil fuel leases and ending fossil fuel subsidies, as well as creating carbon budgets and fossil fuel production limits.

"Change is coming," said Lee. "We need to get out ahead of it."

Power customers in British Columbia, Quebec have faced fees for refusing the installation of smart meters

NB Power Smart Meter Opt-Out Fees reflect cost causation principles set before the Energy and Utilities Board, covering meter reading charges, transmitter-disable options, rollout targets, and education plans across New Brunswick's smart metering program.

 

Key Points

Fees NB Power may apply to customers opting out of smart meters, reflecting cost causation and meter-reading costs.

✅ Based on cost causation and meter reading expenses

✅ BC and Quebec charge monthly opt-out surcharges

✅ Policy finalized during rollout after EUB review

 

NB Power customers who do not want a smart meter installed on their home could be facing a stiff fee for that decision, but so far the utility is not saying how much it might be.  

"It will be based on the principles of cost causation, but we have not gotten into the detail of what that fee would be at this point," said NB Power Senior Vice President of Operations Lori Clark at Energy and Utilities Board hearings on Friday.

In other jurisdictions that have already adopted smart meters, customers not wanting to participate have faced hundreds of dollars in extra charges, while Texas utilities' pullback from smart-home networks shows approaches can differ.

In British Columbia, power customers are charged a meter reading fee of $32.40 per month if they refuse a smart meter, or $20 per month if they accept a smart meter but insist its radio transmitter be turned off. That's a cost of between $240 and $388.80 per year for customers to opt out.

In Quebec, smart meters were installed beginning in 2012. Customers who refused the devices were initially charged $98 to opt out plus a meter reading fee of $17 per month. That was eventually cut by Quebec's energy board in 2014 to a $15 refusal fee and a $5 per month meter reading surcharge.

NB Power said it may be a year or more before it settles on its own fee.

"The opt out policy will be developed and implemented as part of the roll out.  It will be one of the last things we do," said Clark.

 

Customers need to be on board

NB Power is in front of the New Brunswick Energy and Utilities Board seeking permission to spend $122.7 million to install 350,000 smart meters province wide, as neighboring markets grapple with major rate increases that heighten affordability concerns.  

The meters are capable of transmitting consumption data of customers back to NB Power in real time, which the utility said will allow for a number of innovations in pricing and service, and help address old meter inaccuracies that affected some households.

The meters require near universal adoption by customers to maximize their financial benefit — like eliminating more than $20 million a year NB Power currently spends to read meters manually. The utility has said the switch will not succeed if too many customers opt out.

"We certainly wouldn't be looking at making an investment of this size without having the customer with us," said Clark.

On Thursday, Kent County resident Daniel LeBlanc, who along with Roger Richard, is opposing the introduction of smart meters for health reasons, predicted a cool reception for the technology in many parts of the province, given concerns that include health effects and billing disputes in Nova Scotia reported elsewhere.

"If one were to ask most of the people in the rural areas, I'm not sure you would get a lot of takers for this infrastructure," said LeBlanc, who is concerned with the long-term effect microwave frequencies used by the meters to transmit data may have on human health.

That issue is before the EUB next week.

 

Haven't tested the waters

NB Power acknowledged it has not measured public opinion on adopting smart meters but is confident it can convince customers it is a good idea for them and the utility, even as seasonal rate proposals in New Brunswick have prompted consumer backlash.

"People don't understand what the smart meter is," said Clark. "We need to educate our customers first to allow them to make an informed decision so that will be part of the roll out plan."

Clark noted that smart meters, helped by stiff opting out penalties, were eventually accepted by 98 per cent of customers in British Columbia and by 97.4 per cent of customers in Quebec.

"We will check and adjust along the way if there are issues with customer uptake," said Clark.

 

"This is very similar to what has been done in other jurisdictions and they haven't had those challenges."

Surging electricity demand is putting power systems under strain around the world

Global Electricity Demand Surge strains power markets, fuels price volatility, and boosts coal and gas generation as renewables lag, driving emissions, according to the IEA, with grids and clean energy investment crucial through 2024.

 

Key Points

A surge in power use that strained supply, raised prices, and drove power-sector CO2 emissions to record highs.

✅ 6% demand growth in 2021; largest absolute rise ever

✅ Coal up 9%; gas +2%; renewables +6% could not meet demand

✅ Prices doubled vs 2020; volatility hit EU, China, India

 

Global electricity demand surged above pre-pandemic levels in 2021, creating strains in major markets, pushing prices to unprecedented levels and driving the power sector’s emissions to a record high. Electricity is central to modern life and clean electricity is pivotal to energy transitions, but in the absence of faster structural change in the sector, rising demand over the next three years could result in additional market volatility and continued high emissions, according an IEA report released today.

Driven by the rapid economic rebound, and more extreme weather conditions than in 2020, including a colder than average winter, last year’s 6% rise in global electricity demand was the largest in percentage terms since 2010 when the world was recovering from the global financial crisis. In absolute terms, last year’s increase of over 1 500 terawatt-hours was the largest ever, according to the January 2022 edition of the IEA’s semi-annual Electricity Market Report.

The steep increase in demand outstripped the ability of sources of electricity supply to keep pace in some major markets, with shortages of natural gas and coal leading to volatile prices, demand destruction and negative effects on power generators, retailers and end users, notably in China, Europe and India. Around half of last year’s global growth in electricity demand took place in China, where demand grew by an estimated 10%, highlighting that Asia is set to use half of global electricity by 2025 according to the IEA. China and India suffered from power cuts at certain points in the second half of the year because of coal shortages.

“Sharp spikes in electricity prices in recent times have been causing hardship for many households and businesses around the world and risk becoming a driver of social and political tensions,” said IEA Executive Director Fatih Birol. “Policy makers should be taking action now to soften the impacts on the most vulnerable and to address the underlying causes. Higher investment in low-carbon energy technologies including renewables, energy efficiency and nuclear power – alongside an expansion of robust and smart electricity grids – can help us get out of today’s difficulties.”

The IEA’s price index for major wholesale electricity markets almost doubled compared with 2020 and was up 64% from the 2016-2020 average. In Europe, average wholesale electricity prices in the fourth quarter of 2021 were more than four times their 2015-2020 average, and wind and solar generated more electricity than gas in the EU during the year.  Besides Europe, there were also sharp price increases in Japan and India, while they were more moderate in the United States where gas supplies were less perturbed.

Electricity produced from renewable sources grew by 6% in 2021, but it was not enough to keep up with galloping demand. Coal-fired generation grew by 9%, with soaring electricity and coal use serving more than half of the increase in demand and reaching a new all-time peak as high natural gas prices led to gas-to-coal switching. Gas-fired generation grew by 2%, while nuclear increased by 3.5%, almost reaching its 2019 levels. In total, carbon dioxide (CO2) emissions from power generation rose by 7%, also reaching a record high, after having declined the two previous years.

“Emissions from electricity need to decline by 55% by 2030 to meet our Net Zero Emissions by 2050 Scenario, but in the absence of major policy action from governments, those emissions are set to remain around the same level for the next three years,” said Dr Birol. “Not only does this highlight how far off track we currently are from a pathway to net zero emissions by 2050, but it also underscores the massive changes needed for the electricity sector to fulfil its critical role in decarbonising the broader energy system.”

For 2022-2024, the report anticipates electricity demand growing 2.7% a year on average, although the Covid-19 pandemic and high energy prices bring some uncertainty to this outlook. Renewables are set to grow by 8% per year on average, and low-emissions sources are expected to serve more than 90% of net demand growth during this period. We expect nuclear-based generation to grow by 1% annually during the same period.

As a consequence of slowing electricity demand growth and significant renewables additions, fossil fuel-based generation is expected to stagnate in the coming years, and renewables are set to surpass coal by 2025 with coal-fired generation falling slightly as phase-outs and declining competitiveness in the United States and Europe are balanced by growth in markets like China, where electricity demand trends remain a puzzle in recent analyses, and India. Gas-fired generation is seen growing by around 1% a year.
