The much-heralded nuclear "renaissance" appears to have stalled this summer, at least temporarily — not because of unsettled questions over the disposal of radioactive waste, or fear of nuclear accidents, but because the costs of building new reactors is proving prohibitive.

That, at least, was Premier Dalton McGuinty's explanation for his government's recent decision not to proceed with two new reactors for Ontario's Darlington facility. They were expected to cost $6 billion; the final tally from Atomic Energy of Canada Limited, the winning bidder, was rumoured to be closer to $26 billion.

Shortly after, Bruce Power, the private company that operates two nuclear facilities for the McGuinty government, announced that it was pulling the plug on new installations at Nanticoke on Lake Erie and Port Elgin on Lake Huron. It has decided to refurbish existing reactors rather than buy new ones.

Again, the concern was economic. Incredibly — given the brownouts of recent memory and apocalyptic talk of future energy shortages — Ontario is enjoying an electricity surplus. The recession, and cool weather this summer, have diminished demand and new gas-fired stations and wind farms have increased supply — but the trend predates this year.

Since 2006, power use has fallen in Ontario, with another four-per-cent decline predicted this year and surpluses predicted until 2015. In light of this reality, Bruce Power's decision makes perfect business sense.

A related problem for nuclear-power advocates is waning political and public support for AECL, flagship of Canada's state-supported nuclear industry. After its costly failures at Chalk River, the ongoing isotope crisis, and its difficulty finding buyers abroad for its advanced CANDU, the Harper government is contemplating breaking up AECL and selling off any marketable assets.

If Ontario decides not to buy an AECL reactor, the crown corporation's prospects in other countries — and Canada's foothold in the global industry — would be further imperiled. Aware of this, McGuinty is pressing Ottawa to subsidize AECL's bid, in effect, asking Canadian taxpayers to pay for Ontario's nuclear future. It doesn't seem likely, given Harper's disdain for an agency regarded in Tory circles as "a sinkhole."

Uncertainty over AECL's future could also threaten development of a proposed second reactor at New Brunswick's Point Lepreau, the province's energy minister, Jack Keir, said recently.

Elsewhere, while European governments move to embrace nuclear power and memories of Three Mile Island and Chernobyl fade, the nuclear revival is also running into practical roadblocks. Finland's attempt to create a new reactor is three years behind schedule and 50 per cent over budget. Plans to build two reactors in Texas have been postponed. An accident at a German reactor days has revived apprehensions.

But the immediate brake on nuclear expansion is the recession, which has also stalled oil sands development and other environmentally damaging activities. It is expected to be temporary; the industry still has ambitious post-recession plans, including new reactors in Alberta and Saskatchewan, and many political allies. To succeed, however, it will have to come up with the low-cost designs it has long promised.

Meanwhile, there is a window opening for renewables and less controversial alternatives — especially if some of the millions invested in nuclear power were to be re-directed to green options, energy efficiency and conservation. It will take 10 years to build a new reactor (if one is ever approved) and the aging Pickering plant is supposed to reach the end of its useful life by 2014. That means one of two things: a sudden and serious shortage of electricity in coming years, or a concerted effort to find alternatives to expensive nuclear power.

The strongest argument in favour of continued use of nuclear power has always been that it supplies 50 per cent of Ontario's electricity — wind farms, solar, gas-fired electricity plants and other alternatives can't begin to fill that gap. Add to that McGuinty's promise to phase out polluting coal-fired electricity generation by 2014, which puts further strain on supply.

But Amir Shalaby, vice-president of Ontario Power Authority, a provincial oversight agency, doesn't sound pessimistic. In a recent interview, he said the province can order more renewables, import hydro power from Quebec, and find other ways of filling the void left as aging reactors begin to shut down.

Years of fitful efforts at promoting conservation and efficiency might also be paying off — finally. Another stopgap could be running existing nuclear facilities only in high-demand periods in summer, thereby extending their lives. (Although the older the technology, the greater the risk of breakdown.)

While nuclear power still figures prominently in Ontario's plans, the 2007 panic over energy supply appears to have subsided, creating breathing room for provincial energy authorities and opportunities for green alternatives. Emissions-free but still problematic nuclear power will play a role in future supply, but with luck, a diminishing one.

Ottawa sets out to protect its hydro heritage

Ottawa Hydro Substation Heritage Designation highlights Hydro Ottawa's 1920s architecture, Art Deco facades, and municipal utility history, protecting key voltage-reduction sites in Glebe, Carling-Merivale, Holland, King Edward, and Old Ottawa South.

 

Key Points

A city plan to protect Hydro Ottawa's 1920s substations for architecture, utility role, and civic electrical heritage.

✅ Protects five operating voltage-reduction sites citywide

✅ Recognizes Art Deco and early 20th century utility architecture

✅ Allows emergency demolition to ensure grid safety

 

The city of Ottawa is looking to designate five hydro substations built nearly a century ago as heritage structures, a move intended to protect the architectural history of Ottawa's earliest forays into the electricity business, even as Ottawa electricity consumption has shifted in recent years.

All five buildings are still used by Hydro Ottawa to reduce the voltage coming from transmission lines before the electricity is transmitted to homes and businesses, and when severe weather causes outages, Sudbury Hydro crews work to reconnect service across communities.

Electricity came to Ottawa in 1882 when two carbon lamps were installed on LeBreton Flats, heritage planner Anne Fitzpatrick told the city's built heritage subcommittee on Tuesday. It became a lucrative business, and soon a privately owned monopoly that drew public scrutiny similar to debates over retroactive charges in neighboring jurisdictions.

In 1905, city council held a special meeting to buy the electrical company, which led to a dramatic drop in electricity rates for residents, a contrast with recent discussions about peak hydro rates for self-isolating customers.

The substations are now owned by Hydro Ottawa, which agreed to the heritage designations on the condition it not be prevented from emergency demolitions if it needs to address incidents such as damaging storms in Ontario while it works to "preserve public safety and the continuity of critical hydro electrical services."

Built in 1922, the substation at the intersection of Glebe and Bronson avenues was the first to be built by the new municipal electrical department, long before modern battery storage projects became commonplace on Ontario's grid.

The largest of the substations being protected dates back to 1929 and is found at the corner of Carling Avenue and Merivale Road. It was built to accommodate a growing population in areas west of downtown including Hintonburg and Mechanicsville.

The substation on Holland Avenue near the Queensway is different from the others because it was built in 1924 to serve the Ottawa Electric Railway Company. The streetcar company operated from 1891 to 1959, and urban electrical infrastructure can face failures such as the Hydro-Québec manhole fire that left thousands without power.

This substation on King Edward Avenue was built in 1931 and designed by architect William Beattie, who also designed York Street Public School in Lowertown and the substation on Carling Avenue. 

The last substation to be built in a 'bold and decorative style' is at 39 Riverdale Ave. in Old Ottawa South, according to city staff. It was designed in an Art Deco style by prominent architect J. Albert Ewart, who was also behind the Civic Hospital and nearby Southminster Church on Bank Street.

NRC Begins Special Inspection at River Bend Nuclear Power Plant

NRC Special Inspection at River Bend reviews failures of portable emergency diesel generators, nuclear safety measures, and Entergy Operations actions after Fukushima; off-site power loss readiness, remote COVID-19 oversight, and corrective action plans are assessed.

 

Key Points

An NRC review of generator test failures at River Bend, assessing nuclear safety, root causes, and corrective actions.

✅ Evaluates failures of portable emergency diesel generators

✅ Reviews causal analyses and adequacy of corrective actions

✅ Remote COVID-19 oversight; public report expected within 45 days

 

The Nuclear Regulatory Commission has begun a special inspection at the River Bend nuclear power plant, part of broader oversight that includes the Turkey Point renewal application, to review circumstances related to the failure of five portable emergency diesel generators during testing. The plant, operated by Entergy Operations, is located in St. Francisville, La., as nations like France outage risks continue to highlight broader reliability concerns.

The generators are used to supply power to plant systems in the event of a prolonged loss of off-site electrical power coupled with a failure of the permanently installed emergency generators, a concern underscored by incidents such as the SC nuclear plant leak that shut down production for weeks. These portable generators were acquired as part of the facility's safety enhancements mandated by the NRC following the 2011 accident at the Fukushima Dai-ichi facility in Japan, and amid constraints like France limiting output from warm rivers, the emphasis on resilience remains.

The three-member NRC team will develop a chronology of the test failures and evaluate the licensee's causal analyses and the adequacy of corrective actions, informed by lessons from cases like Davis-Besse closure stakes that underscore risk management.

Due to the COVID-19 pandemic, they will complete most of their work remotely, while other regions address constraints such as high river temperatures limiting output for nuclear stations. An inspection report documenting the team's findings, released as global nuclear project milestones continue across the sector, will be publicly available within 45 days of the end of the inspection.

"Knowledge Gap" Is Contributing To On-the-job Electrical Injuries

BC Hydro Trades Electrical Safety addresses electric contact incidents among trade workers, emphasizing power line hazards, overhead lines clearance, the 3 m rule, jobsite planning, and safety training to prevent injuries during spring and summer.

 

Key Points

BC Hydro Trades Electrical Safety is guidance and training to reduce power-line contact risks for trade workers.

✅ Stay at least 3 m from overhead power lines and equipment

✅ Plan worksites and spot hazards before starting tasks

✅ Use BC Hydro electrical awareness training near electricity

 

A BC Hydro report finds serious electrical contact incidents are more common among trades workers, and research shows this is partly due to a knowledge gap in the electricity sector in Canada.

Trade workers were involved in more than 60 per cent of electric contact incidents that led to serious injuries over the last three years, according to BC Hydro.

One-in-five trade workers have also either made contact or had a close call with electric equipment.

A recent worksite electrocution case underscores the consequences of contact.

“New research finds many have had a close call with electricity on the job or have witnessed unsafe work near overhead lines or electrical equipment,” BC Hydro staff said in the report.

“A gap in electrical safety knowledge is a contributing factor in most of these incidents.”

Most electrical contact incidents take place in the spring and summer, when trade workers are working outdoors and are working in close proximity to power lines.

BC Hydro offered tips for trades workers who may work closely to possible electrical contact points:

  • Look up and down – Observe the site beforehand and plan work so you can avoid contact with power lines
  • Stay back – You and your tools should stay at least 3 m away from an overhead power line
  • Call for help – If you come across a fallen power line, or a tree branch or object contacts a line—stay back 10 metres and call 911. Never try and move it yourself. If you must work closer than 3 m to a power line at your worksite, call BC Hydro before you begin.
  • Learn about the risks – BC Hydro offers in-person and online electrical awareness training, such as arc flash training, for anyone who works near electricity.

The report found that 38 per cent of trades workers who participated in the report said they only feel “somewhat informed” about safety measures around working near electricity and 71 per cent were unable to identify the correct distance they should be away from active power lines or electrical equipment.

BC Hydro said trade workers should participate in its electrical awareness training courses, including arc flash training, to make sure all safety measures are taken.

Trump's Pledge to Scrap Offshore Wind Projects

Trump Offshore Wind Pledge signals a push for deregulation over renewable energy, challenging climate policy, green jobs, and coastal development while citing marine ecosystems, navigation, and energy independence amid state-federal permitting and legal hurdles.

 

Key Points

Trump's vow to cancel offshore wind projects favors deregulation and fossil fuels, impacting climate policy and jobs.

✅ Day-one plan to scrap offshore wind leases and permits

✅ Risks to renewable targets, grid mix, and coastal supply chains

✅ Likely court fights and state-federal regulatory conflicts

 

During his tenure as President of the United States, Donald Trump made numerous promises and policy proposals, many of which sparked controversy and debate. One such pledge was his vow to scrap offshore wind projects on "day one" of his presidency. This bold statement, while appealing to certain interests, raised concerns about its potential impact on U.S. offshore wind growth and environmental conservation efforts.

Trump's opposition to offshore wind projects stemmed from various factors, including his skepticism towards renewable energy, even as forecasts point to a $1 trillion offshore wind market in coming years, concerns about aesthetics and property values, and his focus on promoting traditional energy sources like coal and oil. Throughout his presidency, Trump prioritized deregulation and sought to roll back environmental policies introduced by previous administrations, arguing that they stifled economic growth and hindered American energy independence.

The prospect of scrapping offshore wind projects drew mixed reactions from different stakeholders. Supporters of Trump's proposal pointed to potential benefits such as preserving scenic coastal landscapes, protecting marine ecosystems, and addressing concerns about navigational safety and national security. Critics, however, raised valid concerns about the implications of such a decision on the renewable energy sector, including progress toward getting 1 GW on the grid nationwide, climate change mitigation efforts, and job creation in the burgeoning green economy.

Offshore wind energy has emerged as a promising source of clean, renewable power with the potential to reduce greenhouse gas emissions and diversify the energy mix. Countries like Denmark, the United Kingdom, and Germany have made significant investments in offshore wind in Europe, demonstrating its viability as a sustainable energy solution. In the United States, offshore wind projects have gained traction in states like Massachusetts, New York, and New Jersey, where coastal conditions are conducive to wind energy generation.

Trump's pledge to scrap offshore wind projects on "day one" of his presidency raised questions about the feasibility and legality of such a move. While the president has authority over certain aspects of energy policy and regulatory oversight, the development of offshore wind projects often involves multiple stakeholders, including state governments, local communities, private developers, and federal agencies, and actions such as Interior's move on Vineyard Wind illustrate federal leverage in permitting. Any attempt to halt or reverse ongoing projects would likely face legal challenges and regulatory hurdles, potentially delaying or derailing implementation.

Moreover, Trump's stance on offshore wind projects reflected broader debates about the future of energy policy, environmental protection, and economic development. While some argued for prioritizing fossil fuel extraction and traditional energy infrastructure, others advocated for a transition towards clean, renewable energy sources, drawing on lessons from the U.K. about wind deployment, to mitigate climate change and promote sustainable development. The Biden administration, which succeeded the Trump presidency, has signaled a shift towards a more climate-conscious agenda, including support for renewable energy initiatives and commitments to rejoin international agreements like the Paris Climate Accord.

In hindsight, Trump's pledge to scrap offshore wind projects on "day one" of his presidency underscores the complexities of energy policy and the importance of balancing competing interests and priorities. While concerns about aesthetics, property values, and environmental impact are valid, addressing the urgent challenge of climate change requires bold action and innovation in the energy sector. Offshore wind energy presents an opportunity, as seen in the country's biggest offshore wind farm approved in New York, to harness the power of nature in a way that is both environmentally responsible and economically beneficial. As the United States navigates its energy future, finding common ground and forging partnerships will be essential to ensure a sustainable and prosperous tomorrow.

How waves could power a clean energy future

Wave Energy Converters can deliver marine power to the grid, with DOE-backed PacWave enabling offshore testing, robust designs, and renewable electricity from oscillating waves to decarbonize coastal communities and replace diesel in remote regions.

 

Key Points

Wave energy converters are devices that transform waves' oscillatory motion into electricity for the grid or loads.

✅ DOE's PacWave enables full-scale, grid-connected offshore testing.

✅ Multiple designs convert oscillating motion into torque and power.

✅ Ideal for islands, microgrids, and replacing diesel generation.

 

Waves off the coast of the U.S. could generate 2.64 trillion kilowatt hours of electricity per year — that’s about 64% of last year’s total utility-scale electricity generation in the U.S. We won’t need that much, but one day experts do hope that wave energy will comprise about 10-20% of our electricity mix, alongside other marine energy technologies under development today.

“Wave power is really the last missing piece to help us to transition to 100% renewables, ” said Marcus Lehmann, co-founder and CEO of CalWave Power Technologies, one of a number of promising startups focused on building wave energy converters.

But while scientists have long understood the power of waves, it’s proven difficult to build machines that can harness that energy, due to the violent movement and corrosive nature of the ocean, combined with the complex motion of waves themselves, even as a recent wave and tidal market analysis highlights steady advances.

″Winds and currents, they go in one direction. It’s very easy to spin a turbine or a windmill when you’ve got linear movement. The waves really aren’t linear. They’re oscillating. And so we have to be able to turn this oscillatory energy into some sort of catchable form,” said Burke Hales, professor of cceanography at Oregon State University and chief scientist at PacWave, a Department of Energy-funded wave energy test site off the Oregon Coast. Currently under construction, PacWave is set to become the nation’s first full-scale, grid-connected test facility for these technologies, a milestone that parallels U.K. wind power lessons on scaling new industries, when it comes online in the next few years.

“PacWave really represents for us an opportunity to address one of the most critical barriers to enabling wave energy, and that’s getting devices into the open ocean,” said Jennifer Garson, Director of the Water Power Technologies Office at the U.S. Department of Energy.

At the beginning of the year, the DOE announced $25 million in funding for eight wave energy projects to test their technology at PacWave, as offshore wind forecasts underscore the growing investor interest in ocean-based energy. We spoke with a number of these companies, which all have different approaches to turning the oscillatory motion of the waves into electrical power.

Different approaches
Of the eight projects, Bay Area-based CalWave received the largest amount, $7.5 million. 

″The device we’re testing at PacWave will be a larger version of this,” said Lehmann. The x800, our megawatt-class system, produces enough power to power about 3,000 households.”

CalWave’s device operates completely below the surface of the water, and as waves rise and fall, surge forward and backward, and the water moves in a circular motion, the device moves too. Dampers inside the device slow down that motion and convert it into torque, which drives a generator to produce electricity, a principle mirrored in some wind energy kite systems as they harvest aerodynamic forces.

“And so the waves move the system up and down. And every time it moves down, we can generate power, and then the waves bring it back up. And so that oscillating motion, we can turn into electricity just like a wind turbine,” said Lehmann.

Another approach is being piloted by Seattle-based Oscilla Power, which was awarded $1.8 million from the DOE, and is getting ready to deploy its wave energy converter off the coast of Hawaii, at the U.S. Navy Wave Energy Test site.

Oscilla Power’s device is composed of two parts. One part floats on the surface and moves with the waves in all directions — up and down, side to side and rotationally. This float is connected to a large, ring-shaped structure which hangs below the surface, and is designed to stay relatively steady, much like how underwater kites leverage a stable reference to generate power. The difference in motion between the float and the ring generates force on the connecting lines, which is used to rotate a gearbox to drive a generator.

″The system that we’re deploying in Hawaii is what we call the Triton-C. This is a community-scale system,” said Balky Nair, CEO of Oscilla Power. “It’s about a third of the size of our flagship product. It’s designed to be 100 kilowatt rated, and it’s designed for islands and small communities.”

Nair is excited by wave energy’s potential to generate electricity in remote regions, which currently rely on expensive and polluting diesel imports to meet their energy needs when other renewables aren’t available, and similar tidal energy for remote communities efforts in Canada point to viable models. Before wave energy is adopted at-scale, many believe we’ll see wave energy replacing diesel generators in off-the-grid communities.

A third company, C-Power, based in Charlottesville, Virginia, was awarded more than $4 million to test its grid-scale wave energy converter at PacWave. But first, the company wants to commercialize its smaller scale system, the SeaRAY, which is designed for lower-power applications. 

″Think about sensors in the ocean, research, metocean data gathering, maybe it’s monitoring or inspection,” said C-Power CEO Reenst Lesemann on the initial applications of his device.

The SeaRAY consists of two floats and a central body, the nacelle, which contains the drivetrain. As waves pass by, the floats bob up and down, rotating about the nacelle and turning their own respective gearboxes which power the electric generators.

Eventually, C-Power plans to scale up its SeaRAY so that it’s capable of satellite communications and deep water deployments, before building a larger system, called the StingRAY, for terrestrial electricity generation.

Meanwhile, one Swedish company, Eco Wave Power, is taking another approach completely, eschewing offshore technologies in favor of simpler wave power devices that can be installed on breakwaters, piers, and jetties.

“All the expensive conversion machinery, instead of being inside the floaters like in the competing technologies, is on land just like a regular power station. So basically this enables a very low installation, operation, and maintenance cost,” explained CEO Inna Braverman.

Britain Goes Full Week Without Coal Power

Britain Coal-Free Week signals a historic shift to clean energy, with zero coal power, increased natural gas and renewables, lower greenhouse gas emissions, and ambitious UK energy policy targeting a 2025 coal phase-out and decarbonization.

 

Key Points

A seven-day period with no coal power in the UK, signaling cleaner energy and progress on emission reductions.

✅ Seven days of zero coal generation in the UK

✅ Natural gas and renewables dominated the electricity mix

✅ Coal phase-out targeted by 2025; emissions cuts planned

 

For the first time in a century, Britain weaned itself off of coal consumption for an entire week, a coal-free power record for the country.

Reuters reported that Britain went seven days without relying on any power generated by coal-powered stations as the share of coal in the grid continued to hit record lows.

The accomplishment is symbolic of a shift to more clean energy sources, with wind surpassing coal in 2016 and the UK leading the G20 in wind share as of recent years; Britain was home to the first coal-powered plant back in the 1880s.

Today, Britain has some aggressive plans in place to completely eliminate its coal power generation permanently by 2025, with a plan to end coal power underway. In addition, Britain aims to cut its total greenhouse gas emissions by 80 percent from 1990 levels within the next 30 years.

Natural gas was the largest source of power for Britain in 2018, providing 39 percent of the nation's total electricity, as the Great Britain generation dashboard shows. Coal contributed only about 5 percent, though low-carbon generation stalled in 2019 according to reports. Burning natural gas also produces greenhouse gases, but it is much more efficient and greener than coal.

In the U.S., 63.5 percent of electricity generated in 2018 came from fossil fuels. About 35.1 percent was produced from natural gas and 27.4 percent came from coal. In addition, 19.3 percent of electricity came from nuclear power and 17.1 percent came from renewable energy sources, according to the U.S. Energy Information Administration.
