A broken insulator at the Bedeque substation shut down one of the two cables that carries electricity to PEI from the mainland, leaving thousands without electricity.

The problem started at 6 p.m. and took about 3.5 hours for Maritime Electric to repair. At one point 23,000 households were without electricity.

While Maritime Electric has oil-fired generators on the Island, it is heavily reliant on the far less expensive power it can import via two cables under the Northumberland Strait. Those cables are close to capacity, and when one goes down, the electricity grid goes into a partial shutdown to protect the remaining cable.

"One of the things that can damage that type of equipment is overloading it," said Maritime Electric vice-president of corporate planning and energy supply John Gaudet.

"We want to make sure that we take care of them the best we can."

Maritime Electric was able to provide 30 MW of power from the Eastern Kings Wind Farm, saving it from firing up more generators.

"It just was good fortune that the wind was blowing," said Gaudet.

"It was a classic example of wind replacing oil."

The cables to the mainland were installed in 1977. At the time, either one could supply the entire province's needs, but that is no longer the case.

The province has been lobbying the federal government for funding for a new cable to the mainland, in part to export wind power produced on the Island.

Maritime Electric is continuing to investigate why the insulator at the Bedeque substation failed.

BC residents split on going nuclear for electricity generation: survey

BC Energy Debate: Nuclear Power and LNG divides British Columbia, as a new survey weighs zero-emission clean energy, hydroelectric capacity, the Site C dam, EV mandates, energy security, rising costs, and blackout risks.

 

Key Points

A BC-wide debate on power choices balancing nuclear, LNG, hydro, costs, climate goals, EVs, and grid reliability.

✅ Survey: 43% support nuclear, 40% oppose in BC

✅ 55% back LNG expansion, led by Southern BC

✅ Hydro at 90%; Site C adds 1,100 MW by 2025

 

There is a long-term need to produce more electricity to meet population and economic growth needs and, in particular, create new clean energy sources, with two new BC generating stations recently commissioned contributing to capacity.

Increasingly, in the worldwide discourse on climate change, nuclear power plants are being touted as a zero-emission clean energy source, with Ontario exploring large-scale nuclear to expand capacity, and a key solution towards meeting reduced emissions goals. New technological advancements could make nuclear power far safer than existing plant designs.

When queried on whether British Columbia should support nuclear power for electricity generation, respondents in a new province-wide survey by Research Co. were split, with 43% in favour and 40% against.

Levels of support reached 46% in Metro Vancouver, 41% in the Fraser Valley, 44% in Southern BC, 39% in Northern BC, and 36% on Vancouver Island.

The closest nuclear power plant to BC is the Columbia Generating Station, located in southern Washington State.

The safe use of nuclear power came to the forefront following the 2011 Fukushima nuclear disaster when the most powerful earthquake ever recorded in Japan triggered a large tsunami that damaged the plant’s emergency generators. Japan subsequently shut off many of its nuclear power plants and increased its reliance on fossil fuel imports, but in recent years there has been a policy reversal to restart shuttered nuclear plants to provide the nation with improved energy security.

Over the past decade, Germany has also been undergoing a transition away from nuclear power. But in an effort to replace Russian natural gas, Germany is now using more coal for power generation than ever before in decades, while Ontario’s electricity outlook suggests a shift to a dirtier mix, and it is looking to expand its use of liquefied natural gas (LNG).

Last summer, German chancellor Olaf Scholz told the CBC he wants Canada to increase its shipments of LNG gas to Europe. LNG, which is greener compared to coal and oil, is generally seen as a transitionary fuel source for parts of the world that currently depend on heavy polluting fuels for power generation.

When the Research Co. survey asked BC residents whether they support the further development of the province’s LNG industry, including LNG electricity demand that BC Hydro says justifies Site C, 55% of respondents were supportive, while 29% were opposed and 17% undecided.

Support for the expansion of the LNG is highest in Southern BC (67%), followed by the Fraser Valley (56%), Metro Vancouver (also 56%), Northern BC (55%), and Vancouver Island (41%).

A larger proportion of BC residents are against any idea of the provincial government moving to ban the use of natural gas for stoves and heating in new buildings, with 45% opposed and 39% in support.

Significant majorities of BC residents are concerned that energy costs could become too expensive, and a report on coal phase-outs underscores potential cost and effectiveness concerns, with 84% expressing concern for residents and 66% for businesses. As well, 70% are concerned that energy shortages could lead to measures such as rationing and rolling blackouts.

Currently, about 90% of BC’s electricity is produced by hydroelectric dams, but this fluctuates throughout the year — at times, BC imports coal- and gas-generated power from the United States when hydro output is low.

According to BC Hydro’s five-year electrification plan released in September 2021, it is estimated BC has a sufficient supply of clean electricity only by 2030, including the capacity of the Site C dam, which is slated to open in 2025. The $16 billion dam will have an output capacity of 1,100 megawatts or enough power for the equivalent of 450,000 homes.

The provincial government’s strategy for pushing vehicles towards becoming dependent on the electrical grid also necessitates a reliable supply of power, prompting BC Hydro’s first call for power in 15 years to prepare for electrification. Most BC residents support the provincial government’s requirement for all new car and passenger truck sales to be zero-emission by 2035, with 75% supporting the goal and 21% opposed.

Rolls-Royce signs MoU with Exelon for compact nuclear power stations

Rolls-Royce and Exelon UKSMR Partnership accelerates factory-built small modular reactors, nuclear power, clean energy, 440MW units, advanced manufacturing, fleet deployment, net zero goals, and resilient, low-cost baseload generation in the UK and globally.

 

Key Points

A partnership to deploy factory-built SMR stations, providing 440MW low-carbon baseload for the UK and export markets.

✅ 440MW factory-built SMR units with rapid modular assembly

✅ Exelon to operate and enhance high capacity factors

✅ Supports UK net zero, jobs, and export-led manufacturing

 

Rolls-Royce and Exelon Generation have signed a Memorandum of Understanding to pursue the potential for Exelon Generation to operate compact nuclear power stations both in the UK and internationally, including markets such as Canada where New Brunswick SMR questions are prompting public debate today.

Exelon Generation will be using their operational experience to assist Rolls Royce in the development and deployment of the UKSMR.

Rolls-Royce is leading a consortium that is designing a low-cost factory built nuclear power station, known as a small modular reactor (SMR), with UK mini-reactor approval anticipated as development progresses. Its standardised, factory-made components and advanced manufacturing processes push costs down, while the rapid assembly of the modules and components inside a weatherproof canopy on the power station site itself avoid costly schedule disruptions.

The consortium is working with its partners and UK Government to secure a commitment for a fleet of factory built nuclear power stations, each providing 440MW of electricity, to be operational within a decade, helping the UK meet its net zero obligations in line with the green industrial revolution policy set out by government. A fleet deployment in the UK will lead to the creation of new factories that will make the components and modules which will help the economy recover from the Covid-19 pandemic and pave the way for significant export opportunities as well.

The consortium members feature the best of nuclear engineering, construction and infrastructure expertise in Assystem, Atkins, BAM Nuttall, Jacobs, Laing O'Rourke, National Nuclear Laboratory, Nuclear Advanced Manufacturing Research Centre, Rolls-Royce and TWI. Exelon will add valuable operational experience to the team.

Tom Samson, interim Chief Executive Officer of the UKSMR consortium, said: 'Nuclear power is central to tackling climate change and economic recovery, but it must be affordable, reliable and investable and the way we manufacture and assemble our power station brings its cost down to be comparable with offshore wind.

'It's a compelling proposition that could draw new players into the UK's power generation landscape, improving choice for consumers and providing uninterrupted low carbon energy to homes and businesses.

'The opportunity to partner with Exelon is a very exciting prospect for our program, complementing our existing Consortium partnerships with one of the world's largest nuclear operator adds an important dimension to our growth ambitions, embodies the strength of the UK and USA alliance on nuclear matters and reflects wider international moves, such as a Canadian premiers' SMR initiative to accelerate technology development, and offers our future customers the ability to achieve the highest performance standards associated with Exelon's outstanding operational track record.'

The power stations will be built by the UKSMR consortium, before being handed over to be operated by power generation companies. Exelon Generation will work closely with the consortium during the pre-operation period. Exelon Nuclear operates 21 nuclear reactors in America, and U.S. regulators recently issued a final safety evaluation for a NuScale SMR that underscores momentum in the sector. The Exelon nuclear fleet is an integral part of the U.S. clean power mix; it produces more than 158 million megawatt-hours of clean electricity every year.

Bryan Hanson, EVP and COO of Exelon Generation said: 'We believe that SMRs are a crucial part of the world's clean energy mix, as projects like Darlington SMRs advance in Ontario. With our experience both in the US and internationally, Exelon is confident that we can help Rolls Royce ensure SMRs play a key role in the UK's energy future. We've had a very strong record of performance for 20 consecutive years, with a 2019 capacity factor of 95.7 percent. We will leverage this experience to achieve sustainably high capacity factors for the UKSMRs.'

Ralph Hunter, Managing Director of Exelon Nuclear Partners, who runs Exelon's international clean energy business, said: 'We have a strong track record of success to be the operator of choice for the UKSMR. We will help develop operational capability, training and human capacity development in the UK, as utilities such as Ontario Power Generation commit to SMRs abroad, ensuring localisation of skills and a strong culture of safety, performance and efficiency.'

By 2050 a full UK programme of a fleet of factory built nuclear power stations in the UK could create:

Up to 40,000 jobs GBP52BN of value to the UK economy GBP250BN of exports

The current phase of the programme has been jointly funded by all consortium members and UK Research and Innovation.

Vietnam Redefines Offshore Wind Power Regulations

Vietnam Offshore Wind Regulations expand coastal zones to six nautical miles, remove water depth limits, streamline permits, and boost investment, grid integration, and renewable energy capacity across deeper offshore wind resource areas.

 

Key Points

Policies extend sites to six nautical miles, scrap depth limits, and speed permits to scale offshore wind.

✅ Extends offshore zones to six nautical miles from shore

✅ Removes water depth limits to access stronger winds

✅ Streamlines permits, aiding grid integration and finance

 

Vietnam has recently redefined its regulations for offshore wind power projects, marking a significant development in the country's renewable energy ambitions. This strategic shift aims to streamline regulatory processes, enhance project feasibility, and accelerate the deployment of offshore wind energy in Vietnam's coastal regions, amid a trillion-dollar offshore wind market globally.

Regulatory Changes

The Vietnamese government has adjusted offshore wind power regulations by extending the allowable distance from shore for wind farms to six nautical miles (approximately 11 kilometers), a move that aligns with evolving global practices such as Canada's offshore wind plan announced recently by regulators. This expansion from previous limits aims to unlock new areas for development and maximize the utilization of Vietnam's vast offshore wind potential.

Scrapping Depth Restrictions

In addition to extending offshore boundaries, Vietnam has removed restrictions on water depth for offshore wind projects. This revision allows developers to explore deeper waters, where wind resources may be more abundant, thereby diversifying project opportunities and optimizing energy generation capacity.

Strategic Implications

The redefined regulations are expected to stimulate investment in Vietnam's renewable energy sector, attracting domestic and international stakeholders keen on capitalizing on the country's favorable wind resources, with World Bank support for wind underscoring the growing pipeline in developing markets. The move aligns with Vietnam's broader energy diversification goals and commitment to reducing reliance on fossil fuels.

Economic Opportunities

The expansion of offshore wind development zones creates economic opportunities across the value chain, from project planning and construction to operation and maintenance. The influx of investments is anticipated to spur job creation, technology transfer, and infrastructure development in coastal communities, as industry groups like Marine Renewables Canada shift toward offshore wind specialization.

Environmental and Energy Security Benefits

Harnessing offshore wind power contributes to Vietnam's efforts to mitigate greenhouse gas emissions and combat climate change. By integrating renewable energy sources into its energy mix, Vietnam enhances energy security, as seen in the UK offshore wind expansion, reduces dependency on imported fuels, and promotes sustainable economic growth.

Challenges and Considerations

Despite the promising outlook, offshore wind projects face challenges such as technical complexities, environmental impact assessments, and grid integration, as well as exposure to policy risk exemplified by U.S. opposition to offshore wind debates.

Future Outlook

Looking ahead, Vietnam's redefined offshore wind regulations position the country as a key player in the global renewable energy transition, a trend reinforced by progress in offshore wind in Europe elsewhere. Continued policy support, investment facilitation, and technological innovation will be critical in unlocking the full potential of offshore wind power and achieving Vietnam's renewable energy targets.

Conclusion

Vietnam's revision of offshore wind power regulations reflects a proactive approach to advancing renewable energy development and fostering a conducive investment environment. By expanding development zones and eliminating depth restrictions, Vietnam sets the stage for accelerated growth in offshore wind capacity, contributing to both economic prosperity and environmental stewardship. As stakeholders seize opportunities in this evolving landscape, collaboration and innovation will drive Vietnam towards a sustainable energy future powered by offshore wind.

US Grid Gets an Overhaul for Renewables

FERC Transmission Planning Overhaul streamlines interregional grid buildouts, enabling high-voltage lines, renewable integration, and grid reliability to scale, cutting fossil reliance while boosting decarbonization, climate resilience, and affordability across regions facing demand and extreme weather.

 

Key Points

Federal rule updating interregional grid planning to integrate renewables, share costs, and improve reliability.

✅ Accelerates high-voltage, interregional lines for renewable transfer

✅ Optimizes transmission planning and cost allocation frameworks

✅ Boosts grid reliability, resilience, and emissions reductions

 

The US took a significant step towards a cleaner energy future on May 13th, 2024. The Federal Energy Regulatory Commission (FERC) approved the first major update to the country's electric transmission policy in over a decade, while congressional Democrats continue to push for action on aggregated DERs within FERC's remit today. This overhaul aims to streamline the process of building new power lines, specifically those that connect different regions. This improved connectivity is crucial for integrating more renewable energy sources like wind and solar into the national grid.

The current system faces challenges in handling the influx of renewables, and the aging U.S. grid amplifies those hurdles today. Renewable energy sources are variable by nature – the sun doesn't always shine, and the wind doesn't always blow. Traditionally, power grids have relied on constantly running power plants, like coal or natural gas, to meet electricity demands. These plants can be easily adjusted to produce more or less power as needed. However, renewable energy sources require a different approach.

The new FERC policy focuses on building more interregional transmission lines. These high-voltage power lines would allow electricity generated in regions with abundant solar or wind power, and even enable imports of green power from Canada in certain corridors, to be transmitted to areas with lower renewable energy resources. For example, solar energy produced in sunny states like California could be delivered to meet peak demand on the East Coast during hot summer days.

This improved connectivity offers several advantages. Firstly, it allows for a more efficient use of renewable resources. Secondly, it reduces the need for fossil fuel-based power plants, leading to cleaner air and lower greenhouse gas emissions. Finally, a more robust grid is better equipped to handle extreme weather events, which are becoming increasingly common due to climate change, and while Biden's climate law shows mixed results on decarbonization, stronger transmission supports resilience.

The need for an upgrade is undeniable. The Biden administration has set ambitious goals for decarbonizing the power sector by 2035, including proposals for a clean electricity standard as a pathway to those targets. A study by the US Department of Energy estimates that achieving this target will require more than doubling the country's regional transmission capacity and increasing interregional capacity by more than fivefold. The aging US grid is already struggling to keep up with current demands, and without significant improvements, it could face reliability issues in the future.

The FERC's decision has been met with praise from environmental groups and renewable energy companies. They see it as a critical step towards achieving a clean energy future. However, some stakeholders, including investor-owned utilities, have expressed concerns about the potential costs associated with building new transmission lines, citing persistent barriers to development identified in recent Senate testimony. Finding the right balance between efficiency, affordability, and environmental responsibility will be key to the success of this initiative.

The road ahead won't be easy. Building new power lines is a complex process that can face opposition from local communities, and broader disputes over electricity pricing changes often complicate planning and approvals. However, the potential benefits of a modernized grid are significant. By investing in this overhaul, the US is taking a crucial step towards a more reliable, sustainable, and cleaner energy future.

We Energies refiles rate hike request driven by rising nuclear power costs

We Energies rate increase driven by nuclear energy costs at Point Beach, Wisconsin PSC filings, and rising utility rates, affecting electricity prices for residential, commercial, and industrial customers while supporting WEC carbon reduction goals.

 

Key Points

A 2021 utility rate hike to recover Point Beach nuclear costs, modestly raising Wisconsin electricity bills.

✅ Residential bills rise about $0.73 per month

✅ Driven by $55.82/MWh Point Beach contract price

✅ PSC review and consumer advocates assessing alternatives

 

Wisconsin's largest utility company is again asking regulators to raise rates to pay for the rising cost of nuclear energy.

We Energies says it needs to collect an additional $26.5 million next year, an increase of about 3.4%.

For residential customers, that would translate to about 73 cents more per month, or an increase of about 0.7%, while some nearby states face steeper winter rate hikes according to regulators. Commercial and industrial customers would see an increase of 1% to 1.5%, according to documents filed with the Public Service Commission.

If approved, it would be the second rate increase in as many years for about 1.1 million We Energies customers, who saw a roughly 0.7% increase in 2020 after four years of no change, while Manitoba Hydro rate increase has been scaled back for next year, highlighting regional contrasts.

We Energies' sister utility, Wisconsin Public Service Corp., has requested a 0.13% increase, which would add about 8 cents to the average monthly residential bill, which went up 1.6% this year.

We Energies said a rate increase is needed to cover the cost of electricity purchased from the Point Beach nuclear power plant, which according to filings with the Securities Exchange Commission will be $55.82 per megawatt-hour next year.

So far this year, the average wholesale price of electricity in the Midwestern market was a little more than $25.50 per megawatt-hour, and recent capacity market payouts on the largest U.S. grid have fallen sharply, reflecting broader market conditions.

Owned and operated by NextEra Energy Resources, the 1,200-megawatt Point Beach Nuclear Plant is Wisconsin's last operational reactor. We Energies sold the plant for $924 million in 2007 and entered into a contract to purchase its output for the next two decades.

Brendan Conway, a spokesman for WEC Energy Group, said customers have benefited from the sale of the plant, which will supply more than a third of We Energies' demand and is a key component in WEC's strategy to cut 80% of its carbon emissions by 2050, amid broader electrification trends nationwide.

"Without the Point Beach plant, carbon emissions in Wisconsin would be significantly higher," Conway said.

As part of negotiations on its last rate case, WEC agreed to work with consumer advocates and the PSC to review alternatives to the contracted price increases, which were structured to begin rising steeply in 2018.

Tom Content, executive director of the Citizens Utility Board, said the contract will be an issue for We Energies customers into the next decade

"It's a significant source (of energy) for the entire state," Content said. "But nuclear is not cheap."

WEC filed the rate requests Monday, one week after the withdrawing similar applications. Conway said the largely unchanged filings had "undergone additional review by senior management."

WEC last week raised its second quarter profit forecast to 67 to 69 cents per share, up from the previous range of 58 to 62 cents per share.

The company credited better than expected sales in April and May along with operational cost savings and higher authorized profit margin for American Transmission Company, of which WEC is the majority owner.

Wisconsin's other investor-owned utilities have reported lower than expected fuel costs for 2020 and 2021, even as emergency fuel stock programs in New England are expected to cost millions this year.

Alliant Energy has proposed using about $31 million in fuel savings to help freeze rates in 2021, aligning with its carbon-neutral electricity plans as it rolls out long-term strategy, while Xcel Energy is proposing to lower its rates by 0.8% next year and refund its customers about $9.7 million in fuel costs for this year.

Madison Gas and Electric is negotiating a two-year rate structure with consumer groups who are optimistic that fuel savings can help prevent or offset rate increases, though some utilities are exploring higher minimum charges for low-usage customers to recover fixed costs.

BC Hydro rates going up 3 per cent

BC Hydro Rate Freeze Rejection details the BCUC decision enabling a 3% rate increase, citing revenue requirements, debt, and capital costs, affecting electricity bills, with NDP government proposing lifeline rates and low-income relief.

 

Key Points

It is the BCUC ruling allowing a 3% BC Hydro rate hike, citing cost recovery, debt, and capital needs.

✅ BCUC rejects freeze; 3% increase proceeds April 1, 2018

✅ Rationale: cost recovery, debt, capital expenditures

✅ Relief: lifeline rate, $600 grants, winter payment plan

 

The B.C. Utilities Commission has rejected a request by the provincial government to freeze rates at BC Hydro for the coming year, meaning a pending rate increase of three percent will come into effect as higher BC Hydro rates on April 1, 2018.

BC Hydro had asked for the three per cent increase, aligning with a rate increase proposal that would add about $2 a month, but, last year, Energy Minister Michelle Mungall directed the Crown corporation to resubmit its request in order to meet an NDP election promise.

"After years of escalating electricity costs, British Columbians deserve a break on their bills," she said at the time.

However, the utilities commission found there was "insufficient regulatory justification to approve the zero per cent rate increase."

"Even these increases do not fully recover B.C. Hydro's forecast revenue requirement, which includes items such as operating costs, new capital expenditures and carrying costs on capital expenditures," the commission wrote in a news release.

Mungall said she was disappointed by the decision.

"We were always clear we were going to the BCUC. We need to respect the role the BCUC has here for the ratepayers and for the public. I'm very disappointed obviously with their decision."

Mungall blamed the previous government for leaving BC Hydro in a financial state where a rate freeze was ultimately not possible.

Last month, Moody's Investors Service calculated BC Hydro's total debt at $22 billion and said it was one of the province's two credit challenges going forward.

"There's quite a financial mess that is a B.C. Liberal legacy after 16 years of government. We have the responsibility as a new government to clean that up."

B.C. Liberal leader Andrew Wilkinson said it was an example of the new government not living up to its campaign promises.

"British Columbians, particularly those on fixed incomes, believed the B.C. NDP when they promised a freeze on hydro bills. They planned accordingly and are now left in the lurch and face higher expenses. This is a government that stumbles into messes that cost all of us because they put rhetoric ahead of planning," he said.

 

Help on the way?

With the freeze being rejected, Mungall said the government would be going forward on other initiatives to help low-income ratepayers, as advocates' call for change after a fund surplus, including:

Legislating a "lifeline rate" program, allowing people with "demonstrated need" to apply for a lower rate for electricity.

Starting in May, providing an emergency grant of $600 for customers who have an outstanding BC Hydro bill.

Hydro's annual winter payment plan also allows people the chance to spread the payment of bills from December to February out over six months, and, with a two-year rate increase on the horizon, a new pilot program to help people paying their bills begins in July.

Mungall couldn't say whether the government would apply for rate freezes in the future.

"I don't have a crystal ball, and can't predict what might happen in two or three years from now, but we need to act swiftly now," she said.

"I appreciate the [BCUC's] rationale, I understand it, and we'll be moving forward with other alternatives for making life more affordable."
