Officials get tour of Rensselaer power plant project

France Nuclear Power Outages threaten the grid as EDF reactors undergo stress corrosion inspections, maintenance delays, and staff shortages, driving electricity imports, peak-demand curtailment plans, and potential rolling blackouts during a cold snap across Europe.

Key Points

EDF maintenance and stress corrosion cut reactor output, forcing imports and blackouts as cold weather lifts demand.

✅ EDF inspects stress corrosion cracks in reactor piping

✅ Maintenance backlogs and skilled labor shortages slow repairs

✅ Government plans demand cuts, imports, and rolling blackouts

France is bracing for possible power outages in the coming days as falling temperatures push up demand while state-controlled nuclear group EDF struggles to bring more production on line.

WHY CAN'T FRANCE MEET DEMAND?
France is one of the most nuclear-powered countries in the world, with a significant role of nuclear power in its energy mix, typically producing over 70% of its electricity with its fleet of 56 reactors and providing about 15% of Europe's total power through exports.

However, EDF (EDF.PA) has had to take a record number of its ageing reactors offline for maintenance this year just as Europe is struggling to cope with cuts in Russian natural gas supplies used for generating electricity, with electricity prices surging across the continent this year.

That has left France's nuclear output at a 30-year low, and mirrors how Europe is losing nuclear power more broadly, forcing France to import electricity and prepare plans for possible blackouts as a cold snap fuels demand for heating.

WHAT ARE EDF'S MAINTENANCE PROBLEMS?
While EDF normally has a number of its reactors offline for maintenance, it has had far more than usual this year due to what is known as stress corrosion on pipes in some reactors, and during heatwaves river temperature limits have constrained output further.

At the request of France's nuclear safety watchdog, EDF is in the process of inspecting and making repairs across its fleet since detecting cracks in the welding connecting pipes in one reactor at the end of last year.

Years of under-investment in the nuclear sector mean that there is precious little spare capacity to meet demand while reactors are offline for maintenance, and environmental constraints such as limits on energy output during high river temperatures reduce flexibility.

France also lacks specialised welders and other workers in sufficient numbers to be able to make repairs fast enough to get reactors back online.

WHAT IS BEING DONE?
In the very short term, after a summer when power markets hit records as plants buckled in heat, there is little that can be done to get more reactors online faster, leaving the government to plan for voluntary cuts at peak demand periods and limited forced blackouts.

In the very short term, there is little that can be done to get more reactors online faster, leaving the government to plan for voluntary cuts at peak demand periods and limited forced blackouts.

Meanwhile, EDF and others in the French nuclear industry are on a recruitment drive for the next generation of welders, pipe-fitters and boiler makers, going so far as to set up a new school to train them.

President Emmanuel Macron wants a new push in nuclear energy, even as a nuclear power dispute with Germany persists, and has committed to building six new reactors at a cost his government estimates at nearly 52 billion euros ($55 billion).

As a first step, the government is in the process of buying out EDF's minority shareholders and fully nationalising the debt-laden group, which it says is necessary to make the long-term investments in new reactors.

Hydro One Rate Hike reflects Ontario Energy Board approval for higher delivery charges, impacting seasonal customers more than residential classes, funding infrastructure upgrades like wood pole and transformer replacements across Ontario's medium-density service areas.

Key Points

The Hydro One rate hike is an OEB-approved delivery charge increase to fund upgrades, with impacts on seasonal users.

✅ OEB-approved delivery rate increases retroactive to 2018

✅ Seasonal customers see larger monthly bill impacts than residential

✅ Funds pole, transformer replacements and tree trimming work

Hydro One seasonal customers will face bigger increases in their bills than the utility's residential customers as a result of an Ontario Energy Board approval of a rate hike, a topic drawing attention from a utilities watchdog in other provinces as well.

Hydro One received permission to increase its delivery charge, as large projects like the Meaford hydro generation proposal are considered across Ontario, retroactive to last year.

It says it needs the money to maintain and upgrade its infrastructure, including efforts to adapt to climate change, much of which was installed in the 1950s.

The utility is notifying customers that new statements reflect higher delivery rates which were not charged in 2018 and the first half of this year, due to delay in receiving the OEB's permission, similar to delays that can follow an energy board recommendation in other jurisdictions.

The amount that customers' bills will increase by depends not only on how much electricity they use, but also on which rate class they belong to, as well as policy decisions affecting remote connections such as the First Nations electricity line in northern Ontario.

For seasonal customers such as summer cottage owners, the impact on a typical user's bill will be 2.9 per cent more per month for 2018, and 1.7 per cent per month for 2019.

There will be further increases of 1.0 per cent, 1.4 per cent and 1.1 per cent per month in 2020, 2021 and 2022 respectively. 

Typical residential customers will experience smaller increases or rate freezes over the same period.

In the residential medium density class, the rate changes are a 2.0 per cent increase for last year, a decrease of 0.5 per cent this year, and an increase of 0.5 per cent in 2021. There will be no increases in 2020 and 2022.

Seasonal Rate Class — Estimated bill impact per month

2018 - 2.9 %

2019 - 1.7%

2020 - 1.0%

2021 - 1.4%

2022 - 1.1%

Residential Medium Density Rate Class — Estimated bill impact per month

2018 - 2.0%

2019 - -0.5% decrease

2020 - 0.0%

2021 - 0.5%

2022 - 0.0%

A Hydro One spokesperson told tbnewswatch.com that over the next three years, the utility's upgrading plan includes reliability investments such as replacing more than 24,000 wood poles across the province as well as numerous transformers.

In the Thunder Bay area, the spokesperson said, some of the revenue generated by the higher delivery rates will cover the cost of replacing more than 180 poles and trimming hazardous trees around 3,200 kilometres of overhead power lines while sharing electrical safety tips with customers.

Muskrat Falls rate mitigation offsets Newfoundland Power's rate stabilization decrease as NL Hydro begins cost recovery; Public Utilities Board approval enables collections while Labrador-Island Link nears commissioning, stabilizing electricity rates despite megaproject delays, overruns.

Key Points

Muskrat Falls rate mitigation is NL Hydro's cost recovery via power rates to stabilize bills as commissioning nears.

✅ Offsets 6.4% decrease with a 6.1% rate increase

✅ About 6% now funds NL Hydro's rate mitigation

✅ Collections begin as Labrador-Island Link nears commissioning

With their July electricity bill, Newfoundland Power customers have begun paying for Muskrat Falls, though a lump-sum credit was also announced to offset costs and bills haven't significantly increased — yet.

In a July newsletter, Newfoundland Power said electricity bills were set to decrease by 6.4 per cent as part of the annual rate stabilization adjustment, which reflects the cost of electricity generation.

Instead, that decrease has been offset by a 6.1 increase in electricity rates so Newfoundland and Labrador Hydro can begin recovering the cost of Muskrat Falls, with a $5.2-billion federal package also underpinning the project, the $13-billion hydroelectric megaproject that is billions over budget and years behind schedule.

That means for residential customers, electricity rates will decrease to 12.346 cents per kilowatt, though the basic customer charge will go up slightly from $15.81 to $15.83. According to an N.L. Hydro spokesperson, about six per cent of electricity bills will now go toward what it calls a "rate mitigation fund." 

N.L. Hydro claims victory in Muskrat Falls arbitration dispute with Astaldi
Software troubles blamed for $260M Muskrat Falls cost increase, with N.L. power rates stable for now
The spokesperson said N.L. Hydro is expecting the rate increase to result in $43 million this year, according to a recent financial update from the energy corporation — a tiny fraction of the project's cost. 

N.L. Hydro asked the Public Utilities Board to approve the rate increase, a process similar to Nova Scotia's recent 14% approval by its regulator, in May. In a letter, Energy, Industry and Technology Minister Andrew Parsons supported the increase, though he asked N.L. Hydro to keep electricity rates "as close to current levels as possible. 

Province modifies order in council
Muskrat Falls is not yet fully online — largely due to software problems with the Labrador-Island Link transmission line — and an order in council dictated that ratepayers on the island of Newfoundland would not begin paying for the project until the project was fully commissioned. 

The provincial government modified that order in council so N.L. Hydro can begin collecting costs associated with Muskrat Falls once the project is "nearing" commissioning.

In June, N.L. Hydro said the project was expected to finally be completed by the end of the year.

In an interview with CBC News, Progressive Conservative interim leader David Brazil said the decision to begin recovering the cost of Muskrat Falls from consumers should have been delayed.

"There was an opportunity here for people to get some reprieve when it came to their electricity bills and this administration chose not to do that, not to help the people while they're struggling," he said.

In a statement, Parsons said reducing the rate was not an option, and would have resulted in increased borrowing costs for Muskrat Falls.

"Reducing the rate for one year to have it increase significantly the following year is not consistent with rate mitigation and also places an increased financial burden on taxpayers one year from now," Parsons said.

Decision 'reasonable': Consumer advocate
Brazil said his party didn't know the payments from Muskrat Falls would start in July, and criticized the government for not being more transparent.

Newfoundland and Labrador consumer advocate Dennis Browne said the decision to begin collecting costs from consumers was "reasonable."

"We're into a financial hole due to Muskrat Falls, and what has happened is in order to stabilize rates, we have gone into rate stabilization efforts," he said.

In February, the provincial and federal governments signed a complex agreement to shield ratepayers aimed at softening the worst of the financial impact from Muskrat Falls. Browne noted even with the agreement, the provincial government will have to pay hundreds of millions in order to stabilize electricity rates.

"Muskrat Falls would cost us $0.23 a kilowatt, and that is out of the range of affordability for most people, and that's why we're into rate mitigation," he said. "This was part of a rate mitigation effort, and I accepted it as part of that."

Canada 100% Renewable Power by 2035 envisions a decentralized grid built on wind, solar, energy storage, and efficiency, delivering zero-emission, resilient, low-cost electricity while phasing out nuclear and gas to meet net-zero targets.

Key Points

Zero-emission, decentralized grid using wind, solar, and storage, plus efficiency, to retire fossil and nuclear by 2035.

✅ Scale wind and solar 18x with storage for reliability.

✅ Phase out nuclear and gas; no CCS or offsets needed.

✅ Modernize grids and codes; boost efficiency, jobs, and affordability.

A powerful derecho that left nearly a million people without power in Ontario and Quebec on May 21 was a reminder of the critical importance of electricity in our daily lives.

Canada’s electrical infrastructure could be more resilient to such events, while being carbon-emission free and provide low-cost electricity with a decentralized grid powered by 100 per cent renewable energy, according to a new study from the David Suzuki Foundation (DSF), a vision of an electric, connected and clean future if the country chooses.

This could be accomplished by 2035 by building a lot more solar and wind, despite indications that demand for solar electricity has lagged in Canada, adding energy storage, while increasing the energy efficiency in buildings, and modernizing provincial energy grids. As this happens, nuclear energy and gas power would be phased out. There would also be no need for carbon capture and storage nor carbon offsets, the modeling study concluded.

“Solar and wind are the cheapest sources of electricity generation in history,” said study co-author Stephen Thomas, a mechanical engineer and climate solutions policy analyst at the DSF.

“There are no technical barriers to reaching 100 per cent zero-emission electricity by 2035 nationwide,” Thomas told The Weather Network (TWN). However, there are considerable institutional and political barriers to be overcome, he said.

Other countries face similar barriers and many have found ways to reduce their emissions; for example, the U.S. grid's slow path to 100% renewables illustrates these challenges. There are enormous benefits including improved air quality and health, up to 75,000 new jobs annually, and lower electricity costs. Carbon emissions would be reduced by 200 million tons a year by 2050, just over one quarter of the reductions needed for Canada to meet its overall net zero target, the study stated.

Building a net-zero carbon electricity system by 2035 is a key part of Canada’s 2030 Emissions Reduction Plan. Currently over 80 per cent of the nation’s electricity comes from non-carbon sources including a 15 per cent contribution from nuclear, with solar capacity nearing a 5 GW milestone nationally. How the final 20 per cent will be emission-free is currently under discussion.

The Shifting Power study envisions an 18-fold increase in wind and solar energy, with the Prairie provinces expected to lead growth, along with a big increase in Canada’s electrical generation capacity to bridge the 20 per cent gap as well as replacing existing nuclear power.

The report does not see a future role for nuclear power due to the high costs of refurbishing existing plants, including the challenges with disposal of radioactive wastes and decommissioning plants at their end of life. As for the oft-proposed small modular nuclear reactors, their costs will likely “be much more costly than renewables,” according to the report.

There are no technical barriers to building a bigger, cleaner, and smarter electricity system, agrees Caroline Lee, co-author of the Canadian Climate Institute’s study on net-zero electricity, “The Big Switch” released in May. However, as Lee previously told TWN, there are substantial institutional and political barriers.

In many respects, the Shifting Power study is similar to Lee’s study except it phases out nuclear power, forecasts a reduction in hydro power generation, and does not require any carbon capture and storage, she told TWN. Those are replaced with a lot more wind generation and more storage capacity.

“There are strengths and weaknesses to both approaches. We can do either but need a wide debate on what kind of electricity system we want,” Lee said.

That debate has to happen immediately because there is an enormous amount of work to do. When it comes to energy infrastructure, nearly everything “we put in the ground has to be wind, solar, or storage” to meet the 2035 deadline, she said.

There is no path to net zero by 2050 without a zero-emissions electricity system well before that date. Here are some of the necessary steps the report provided:

Create a range of skills training programs for renewable energy construction and installation as well as building retrofits.

Prioritize energy efficiency and conservation across all sectors through regulations such as building codes.

Ensure communities and individuals are fully informed and can decide if they wish to benefit from hosting energy generation infrastructure.

Create a national energy poverty strategy to ensure affordable access.

Strong and clear federal and provincial rules for utilities that mandate zero-emission electricity by 2035.

For Indigenous communities, make sure ownership opportunities are available along with decision-making power.

Canada should move as fast as possible to 100 per cent renewable energy to gain the benefits of lower energy costs, less pollution, and reduced carbon emissions, says Stanford University engineer and energy expert Mark Jacobson.

“Canada has so many clean, renewable energy resources that it is one of the easier countries [that can] transition away from fossil fuels,” Jacobson told TWN.

For the past decade, Jacobson has been producing studies and technical reports on 100 per cent renewable energy, including a new one for Canada, even as Canada is often seen as a solar power laggard today. The Stanford report, A Solution to Global Warming, Air Pollution, and Energy Insecurity for Canada, says a 100 per cent transition by 2035 timeline is ideal. Where it differs from DSF’s Shifting Power report is that it envisions offshore wind and rooftop solar panels which the latter did not.

“Our report is very conservative. Much more is possible,” agrees Thomas.

“We’re lagging behind. Canadians really want to get going on building solutions and getting the benefits of a zero emissions electricity system.”

UK Net Zero Policy Delay shifts EV sales ban to 2035, eases boiler phase-outs, keeps ZEV mandate, backs North Sea oil and gas, accelerates onshore wind and grid upgrades while targeting 2050 emissions goals.

Key Points

Delay moves EV and heating targets to 2035, tweaks mandates, and shifts energy policy, keeping the 2050 net zero goal.

✅ EV sales ban shifts to 2035; ZEV mandate trajectory unchanged

✅ Heat pump grants rise to £7,500; boiler phase-out eased

✅ North Sea oil, onshore wind, grid and nuclear plans advance

British Prime Minister Rishi Sunak has said he would delay targets for changing cars and domestic heating to maintain the consent of the British people in the switch to net zero as part of the global energy transition under way.

Sunak said Britain was still committed to achieving net zero emissions by 2050, similar to Canada's race to net zero goals, and denied watering down its climate targets.

Here are some of the current emissions targets for Britain's top polluting sectors and how the announcement impacts them.

TRANSPORTATION
Transport accounts for more than a third (34%) of Britain's total carbon dioxide (CO2) emissions, the most of any sector.

Sunak announced a delay to introducing a ban on new petrol and diesel cars and vans. It will now come into force in 2035 rather than in 2030.

There were more than 1.1 million electric cars in use on UK roads as of April - up by more than half from the previous year to account for roughly one in every 32 cars, according to the country's auto industry trade body.

The current 2030 target was introduced in November 2020 as a central part of then-Prime Minister Boris Johnson's plans for a "green revolution". As recently as Monday, transport minister Mark Harper restated government support for the policy.

Britain’s independent climate advisers, the Climate Change Committee, estimated a 2030 phase out of petrol, diesel and hybrid vehicles could save up to 110 million tons of carbon dioxide equivalent emissions compared with a 2035 phase out.

ohnson's policy already allowed for the continued sale of hybrid cars and vans that can drive long stretches without emitting carbon until 2035.

The transition is governed by a zero-emission vehicle (ZEV) mandate, a shift echoed by New Zealand's electricity transition debates, which means manufacturers must ensure an increasing proportion of the vehicles they sell in the UK are electric.

The current proposal is for 22% of a car manufacturer's sales to be electric in 2024, rising incrementally each year to 100% in 2035.

The government said on Wednesday that all sales of new cars from 2035 would still be zero emission.

Sunak said that proposals that would govern how many passengers people should have in a car, or proposals for new taxes to discourage flying, would be scrapped.

RESIDENTIAL
Residential emissions, the bulk of which come from heating, make up around 17% of the country's CO2 emissions.

The government has a target to reduce Britain's energy consumption from buildings and industry by 15% by 2030, and had set a target to phase out installing new and replacement gas boilers from 2035, as the UK moves towards heat pumps, amid an IEA report on Canada's power needs noting more electricity will be required.

Sunak said people would have more time to transition, and the government said that off-gas-grid homes could continue to install oil and liquefied petroleum gas boilers until 2035, rather than being phased out from 2026.

However, his announcements that the government would not force anyone to rip out an existing boiler and that people would only have to make the switch when replacing one from 2035 restated existing policy.

He also said there would be an exemption so some households would never have to switch, but the government would increase an upgrade scheme that gives people cash to replace their boilers by 50% to 7,500 pounds ($9,296.25).

Currently almost 80% of British homes are heated by gas boilers. In 2022, 72,000 heat pumps were installed. The government had set a target of 600,000 heat pump installations per year by 2028.

A study for Scottish Power and WWF UK in June found that 6 million homes would need to be better insulated by 2030 to meet the government's target to reduce household energy consumption, but current policies are only expected to deliver 1.1 million.

The study, conducted by Frontier Economics, added that 1.5 million new homes would still need heat pumps installed by 2030.

Sunak said that the government would subsidise people who wanted to make their homes energy efficient but never force a household to do it.

The government also said it was scrapping policies that would force landlords to upgrade the energy efficiency of their properties.

ENERGY
The energy sector itself is a big emitter of greenhouse gases, contributing around a quarter of Britain's emissions, though the UK carbon tax on coal has driven substantial cuts in coal-fired electricity in recent years.

In July, Britain committed to granting hundreds of licences for North Sea oil and gas extraction as part of efforts to become more energy independent.

Sunak said he would not ban new oil and gas in the North Sea, and that future carbon budgets for governments would have to be considered alongside the plans to meet them.

He said the government would shortly bring forward new plans for energy infrastructure to improve Britain's grid, including the UK energy plan, while speeding up planning.

Offshore wind power developers warned earlier this month that Britain's climate goals could be at risk, even as efforts like cleaning up Canada's electricity highlight the importance of power-sector decarbonization, after a subsidy auction for new renewable energy projects did not attract any investment in those planned off British coasts.

Britain is aiming to develop 50 gigawatts (GW) of offshore wind capacity by 2030, up from around 14 GW now.

Sunak highlighted that Britain is lifting a ban on onshore wind, investing in carbon capture and building new nuclear power stations.

TEP Undergrounding Policy prioritizes selective underground power lines to manage wildfire risk, engineering costs, and ratepayer impacts, balancing transmission and distribution reliability with right-of-way, safety, and vegetation management per Arizona regulators.

Key Points

A selective TEP approach to bury lines where safety, engineering, and cost justify undergrounding.

✅ Selective undergrounding for feeders near substations

✅ Balances wildfire mitigation, reliability, and ratepayer costs

✅ Follows ACC rules, BLM and USFS vegetation management

Though wildfires in California caused by power lines have prompted calls for more underground lines, Tucson Electric Power Co. plans to keep to its policy of burying lines selectively for safety.

Like many other utilities, TEP typically doesn’t install its long-range, high-voltage transmission lines, such as the TransWest Express project, and distribution equipment underground because of higher costs that would be passed on to ratepayers, TEP spokesman Joe Barrios said.

But the company will sometimes bury lower-voltage lines and equipment where it is cost-effective or needed for safety as utilities adapt to climate change across North America, or if customers or developers are willing to pay the higher installation costs

Underground installations generally include additional engineering expenses, right-of-way acquisition for projects like the New England Clean Power Link in other regions, and added labor and materials, Barrios said.

“This practice avoids passing along unnecessary costs to customers through their rates, so that all customers are not asked to subsidize a discretionary expenditure that primarily benefits residents or property owners in one small area of our service territory,” he said, adding that the Arizona Corporation Commission has supported the company’s policy.

Even so, TEP will place equipment underground in some circumstances if engineering or safety concerns, including electrical safety tips that utilities promote during storm season, justify the additional cost of underground installation, Barrios said.

In fact, lower-voltage “feeder” lines emerging from distribution substations are typically installed underground until the lines reach a point where they can be safely brought above ground, he added.

While in California PG&E has shut off power during windy weather to avoid wildfires in forested areas traversed by its power lines after events like the Drum Fire last June, TEP doesn’t face the same kind of wildfire risk, Barrios said.

Most of TEP’s 5,000 miles of transmission and distribution lines aren’t located in heavily forested areas that would raise fire concerns, though large urban systems have seen outages after station fires in Los Angeles, he said.

However, TEP has an active program of monitoring transmission lines and trimming vegetation to maintain a fire-safety buffer zone and address risks from vandalism such as copper theft where applicable, in compliance with federal regulations and in cooperation with the U.S. Bureau of Land Management and the U.S. Forest Service.
