Hydro Ottawa has completed the purchase, first announced in June 2012, of three hydroelectric plants and a 38.3 percent interest in the Ring Dam and remaining water rights at Chaudière Falls from Domtar Corporation for $46 million.

"This presents a tremendous opportunity for Ontario to add 21 megawatts of renewable run-of-the river hydro power, with the potential to expand that to more than 40 megawatts as we explore additional opportunities at this site," said Hydro Ottawa President and CEO Bryce Conrad.

"The Chaudière Falls generating stations have powered Ottawa's industrial expansion for over a century," said Ottawa Mayor Jim Watson. "What many people don't know is that Canada's oldest surviving hydroelectric facility still operates right here in the nation's capital."

Prior to the purchase, Hydro Ottawa already had over 100 years of experience operating hydroelectric plants at Chaudière Falls, where it owns and operates three plants, with Generating Station #2 originally built in 1891 and Generating Station #4 built in 1900. Both stations have been refurbished.

With the closing of the purchase of the three hydroelectric stations from Domtar, Hydro Ottawa's hydroelectric generating capacity will more than double to 38 megawatts, enabling the company to generate renewable energy for roughly 28,000 households.

Hydro Ottawa Holding Inc. Hydro Ottawa owns and operates two subsidiary companies, Hydro Ottawa Limited and Energy Ottawa Inc. Hydro Ottawa Limited is the third-largest municipally-owned electrical utility in Ontario.

Ontario tables legislation to lower electricity rates

Ontario Clean Energy Adjustment lowers hydro bills by shifting global adjustment costs, cutting time-of-use rates, and using OPG debt financing; ratepayers get inflation-capped increases for four years, then repay costs over 20 years.

 

Key Points

A 20-year line item repaying debt used to lower rates for 10 years by shifting global adjustment costs off hydro bills.

✅ 17% average bill cut takes effect after royal assent

✅ OPG-managed entity assumes debt for 10 years

✅ 20-year surcharge repays up to $28B plus interest

 

Ontarians will see lowered hydro bills for the next 10 years, but will then pay higher costs for the following 20 years, under new legislation tabled Thursday.

Ten weeks after announcing its plan to lower hydro bills, the Liberal government introduced legislation to lower time-of-use rates, take the cost of low-income and rural support programs off bills, and introduce new social programs.

It will lower time-of-use rates by removing from bills a portion of the global adjustment, a charge consumers pay for above-market rates to power producers. For the next 10 years, a new entity overseen by Ontario Power Generation will take on debt to pay that difference.

Then, the cost of paying back that debt with interest -- which the government says will be up to $28 billion -- will go back onto ratepayers' bills for the next 20 years as a "Clean Energy Adjustment."

An average 17-per-cent cut to bills will take effect 15 days after the hydro legislation receives royal assent, even as a Nov. 1 rate increase was set by the Ontario Energy Board, but there are just eight sitting days left before the Ontario legislature breaks for the summer. Energy Minister Glenn Thibeault insisted that leaves the opposition "plenty" of time for review and debate.

Premier Kathleen Wynne promised to cut hydro bills and later defended a 25% rate cut after widespread anger over rising costs helped send her approval ratings to record lows.

Electricity bills in the province have roughly doubled in the last decade, due in part to green energy initiatives, and Thibeault said the goal of this plan is to better spread out those costs.

"Like the mortgage on your house, this regime will cost more as we refinance over a longer period of time, but this is a more equitable and fair approach when we consider the lifespan of the clean energy investments, and generating stations across our province," he said.

NDP critic Peter Tabuns called it a "get-through-the-election" next June plan.

"We're going to take on a huge debt so Kathleen Wynne can look good on the hustings in the next few months and for decades we're going to pay for it," he said.

The legislation also holds rate increases to inflation for the next four years. After that, they'll rise more quickly, as illustrated by a leaked cabinet document the Progressive Conservatives unveiled Thursday.

The Liberals dismissed the document as containing outdated projections, but confirmed that it went before cabinet at some point before the government decided to go ahead with the hydro plan.

From about 2027 onward -- when consumers would start paying off the debt associated with the hydro plan -- Ontario electricity consumers will be paying about 12 per cent more than they would without the Liberal government's plan to cut costs in the short term, even though a deal with Quebec was not expected to reduce hydro bills, the government document projected.

But that was just one of many projections, said Energy Minister Glenn Thibeault.

"We have been working on this plan for months, and as we worked on it the documents and calculations evolved," he said.

The government's long-term energy plan is set to be updated this spring, and Thibeault said it will provide a more accurate look at how the hydro plan will reduce rates, even as a recovery rate could lead to higher hydro bills in certain circumstances.

Progressive Conservative critic Todd Smith said the "Clean Energy Adjustment" is nothing more than a revamped debt retirement charge, which was on bills from 2002 to 2016 to pay down debt left over from the old Ontario Hydro, the province's giant electrical utility that was split into multiple agencies in 1999 under the previous Conservative government.

"The minister can call it whatever he wants but it's right there in the graph, that there is going to be a new charge on the line," Smith said. "It's the debt retirement charge on steroids."

Climate change poses high credit risks for nuclear power plants: Moody's

Nuclear Plant Climate Risks span flood risk, heat stress, and water scarcity, threatening operations, safety systems, and steam generation; resilience depends on mitigation investments, cooling-water management, and adaptive maintenance strategies.

 

Key Points

Climate-driven threats to nuclear plants: floods, heat, and water stress requiring resilience and mitigation.

✅ Flooding threats to safety and cooling systems

✅ Heat stress reduces thermal efficiency and output

✅ Water scarcity risks limit cooling capacity

 

 

Climate change can affect every aspect of nuclear plant operations like fuel handling, power and steam generation and the need for resilient power systems planning, maintenance, safety systems and waste processing, the credit rating agency said.

However, the ultimate credit impact will depend upon the ability of plant operators to invest in carbon-free electricity and other mitigating measures to manage these risks, it added.
Close proximity to large water bodies increase the risk of damage to plant equipment that helps ensure safe operation, the agency said in a note.

Moody’s noted that about 37 gigawatts (GW) of U.S. nuclear capacity is expected to have elevated exposure to flood risk and 48 GW elevated exposure to combined rising heat, extreme heat costs and water stress caused by climate change.

Parts of the Midwest and southern Florida face the highest levels of heat stress, while the Rocky Mountain region and California face the greatest reduction in the availability of future water supply, illustrating the need for adapting power generation to drought strategies, it said.

Nuclear plants seeking to extend their operations by 20, or even 40 years, beyond their existing 40-year licenses in support of sustaining U.S. nuclear power and decarbonization face this climate hazard and may require capital investment adjustments, Moody’s said, as companies such as Duke Energy climate report respond to investor pressure for climate transparency.

“Some of these investments will help prepare for the increasing severity and frequency of extreme weather events, highlighting that the US electric grid is not designed for climate impacts today.”

Portsmouth residents voice concerns over noise, flicker generated by turbine

Portsmouth Wind Turbine Complaints highlight noise, shadow flicker, resident impacts, Town Council hearings, and Green Development mitigation plans near Portsmouth High School, covering renewable energy output, PPAs, and community compliance.

 

Key Points

Resident reports of noise and shadow flicker near Portsmouth High School, prompting review and mitigation efforts.

✅ Noise exceeds ambient levels seasonally, residents report fatigue.

✅ Shadow flicker lasts up to 90 minutes on affected homes.

✅ Town tasks developer to meet neighbors and propose mitigation.

 

The combination of the noise and shadows generated by the town’s wind turbine has rankled some neighbors who voiced their frustration to the Town Council during its meeting Monday.

Mark DePasquale, the founder and chairman of the company that owns the turbine, tried to reassure them with promises to address the bothersome conditions.

David Souza, a lifelong town resident who lives on Lowell Drive, showed videos of the repeated, flashing shadows cast on his home by the three blades spinning.

“I am a firefighter. I need to get my sleep,” he said. “And now it’s starting to affect my job. I’m tired.”

Town Council President Keith Hamilton tasked DePasquale with meeting with the neighbors and returning with an update in a month. “What I do need you to do, Mr. DePasquale, is to follow through with all these people.”

DePasquale said he was unaware of the flurry of complaints lodged by the residents Monday. His company had only heard of one complaint. “If I knew there was an issue before tonight, we would have responded,” he said.

His company, Green Development LLC, formerly Wind Energy Development LLC, installed the 279-foot-tall turbine near Portsmouth High School that started running in August 2016, as offshore developers like Deepwater Wind in Massachusetts plan major construction nearby. It replaced another turbine installed by a separate company that broke down in 2012.

In November 2014, the town signed an agreement with Wind Energy Development to take down the existing turbine, pay off the remaining $1.45 million of the bond the town took out to install it and put up a new turbine, amid broader legal debates like the Cornwall wind farm ruling that can affect project timelines.

In exchange, Wind Energy Development sells a portion of the energy generated by the turbine to the town at a rate of 15.5 cents per kilowatt hour for 25 years. Some of the energy generated is sold to the town of Coventry.

“We took down (the old turbine) and paid off the debt,” DePasquale said, noting that cancellations can carry high costs as seen in Ontario wind project penalties for scrapping projects. “I have no problem doing whatever the council wants … There was an economic decision made to pay off the bond and build something better.”

The turbine was on pace to produce 4 million-plus kilowatt hours per year, Michelle Carpenter, the chief operating officer of Wind Energy Development, said last April. It generates enough energy to power all municipal and school buildings in town, she said, while places like Summerside’s wind power show similarly strong output.

The constant stream of shadows cast on certain homes in the area can last for as long as an hour-and-a-half, according to Souza. “We shouldn’t have to put up with this,” he said.

Sprague Street resident John Vegas said the turbine’s noise, especially in late August, is louder than the neighborhood’s ambient noise.

“Throughout the summer, there’s almost no flicker, but this time of year it’s very prominent,” Vegas added. “It can be every day.”

He mentioned neighbors needed to be better organized to get results.

“When the residents purchased our properties we did not have this wind turbine in our backyard,” Souza said in a memo. “Due to the wind turbine … our quality of life has suffered.”

After the discussion, the council unanimously voted to allow Green Development to sublease excess energy to the Rhode Island Convention Center Authority, a similar agreement to the one the company struck with Coventry, as regional New England solar growth adds pressure on grid upgrade planning.

“This has to be a sustainable solution,” DePasquale said. “We will work together with the town on a solution.”

Smaller, cheaper, safer: Next-gen nuclear power, explained

MARVEL microreactor debuts at Idaho National Laboratory as a 100 kW, liquid-metal-cooled, zero-emissions generator powering a nuclear microgrid, integrating wind and solar for firm, clean energy in advanced nuclear applications research.

 

Key Points

A 100 kW, liquid-metal-cooled INL reactor powering a nuclear microgrid and showcasing zero-emissions clean energy.

✅ 100 kW liquid-metal-cooled microreactor at INL

✅ Powers first nuclear microgrid for applications testing

✅ Integrates with wind and solar for firm clean power

 

Inside the Transient Reactor Test Facility, a towering, windowless gray block surrounded by barbed wire, researchers are about to embark on a mission to solve one of humanity’s greatest problems with a tiny device.

Next year, they will begin construction on the MARVEL reactor. MARVEL stands for Microreactor Applications Research Validation and EvaLuation. It’s a first-of-a-kind nuclear power generator with a mini-reactor design that is cooled with liquid metal and produces 100 kilowatts of energy. By 2024, researchers expect MARVEL to be the zero-emissions engine of the world’s first nuclear microgrid at Idaho National Laboratory (INL).

“Micro” and “tiny,” of course, are relative. MARVEL stands 15 feet tall, weighs 2,000 pounds, and can fit in a semi-truck trailer. But it's minuscule compared to conventional nuclear power plants, which span acres, produces gigawatts of electricity to power whole states, and can take more than a decade to build.

For INL, where scientists have tested dozens of reactors over the decades across an area three-quarters the size of Rhode Island, it’s a radical reimagining of the technology. This advanced reactor design could help overcome the biggest obstacles to nuclear energy: safety, efficiency, scale, cost, and competition. MARVEL is an experiment to see how all these pieces could fit together in the real world.

“It’s an applications test reactor where we’re going to try to figure out how we extract heat and energy from a nuclear reactor and apply it — and combine it with wind, solar, and other energy sources,” said Yasir Arafat, head of the MARVEL program.

The project, however, comes at a time when nuclear power is getting pulled in wildly different directions, from phase-outs to new strategies like the UK’s green industrial revolution that shapes upcoming reactors.

Germany just shut down its last nuclear reactors. The U.S. just started up its first new reactor in 30 years, underscoring a shift. France, the country with the largest share of nuclear energy on its grid, saw its atomic power output decline to its lowest since 1988 last year. Around the world, there are currently 60 nuclear reactors under construction, with 22 in China alone.

But the world is hungrier than ever for energy. Overall electricity demand is growing: Global electricity needs will increase nearly 70 percent by 2050 compared to today’s consumption, according to the Energy Information Administration. At the same time, the constraints are getting tighter. Most countries worldwide, including the U.S., have committed to net-zero goals by the middle of the century, even as demand rises.

To meet this energy demand without worsening climate change, the U.S. Energy Department’s report on advanced nuclear energy released in March said, “the U.S. will need ~550–770 [gigawatts] of additional clean, firm capacity to reach net-zero; nuclear power is one of the few proven options that could deliver this at scale.”

The U.S. government is now renewing its bets on nuclear power to produce steady electricity without emitting greenhouse gases. The Bipartisan Infrastructure Law included $6 billion to keep existing nuclear power plants running. In addition, the Inflation Reduction Act, the U.S. government’s largest investment in countering climate change, includes several provisions to benefit atomic power, including tax credits for zero-emissions energy.

“It’s a game changer,” said John Wagner, director of INL.

The tech sector is jumping in, too, as atomic energy heats up across startups and investors. In 2021, venture capital firms poured $3.4 billion into nuclear energy startups. They’re also pouring money into even more far-out ideas, like nuclear fusion power. Public opinion has also started moving. An April Gallup poll found that 55 percent of Americans favour and 44 percent oppose using atomic energy, the highest levels of support in 10 years.

Group to create Canadian cyber standards for electricity sector IoT devices

Canadian Industrial IoT Cybersecurity Standards aim to unify device security for utilities, smart grids, SCADA, and OT systems, aligning with NERC CIP, enabling certification, trust marks, compliance testing, and safer energy sector deployments.

 

Key Points

National standards to secure industrial IoT for utilities and grids, enabling certification and NERC CIP alignment.

✅ Aligns with NERC CIP and NIST frameworks for energy sector security

✅ Defines certification, testing tools, and a trusted device repository

✅ Enhances OT, SCADA, and smart grid resilience against cyber threats

 

The Canadian energy sector has been buying Internet-connected sensors for monitoring a range of activities in generating plants, distribution networks facing harsh weather risks and home smart meters for several years. However, so far industrial IoT device makers have been creating their own security standards for devices, leaving energy producers and utilities at their mercy.

The industry hopes to change that by creating national cybersecurity standards for industrial IoT devices, with the goal of improving its ability to predict, prevent, respond to and recover from cyber threats, such as emerging ransomware attacks across the grid.

To help, the federal government today announced an $818,000 grant support a CIO Strategy Council project oversee the setting of standards.

In an interview council executive director Keith Jansa said the money will help a three-year effort that will include holding a set of cross-country meetings with industry, government, academics and interest groups to create the standards, tools to be able to test devices against the standards and the development of product repository of IoT safe devices companies can consult before making purchases.

“The challenge is there are a number of these devices that will be coming online over the next few years,” Jansa said. “IoT devices are designed for convenience and not for security, so how do you ensure that a technology an electricity utility secures is in fact safeguarded against cyber threats? Currently, there is no associated trust mark or certification that gives confidence associated with these devices.”

He also said the council will work with the North American Electric Reliability Corporation (NERC), which sets North American-wide utility safety procedural standards and informs efforts on protecting the power grid across jurisdictions. The industrial IoT standards will be product standards.

According to Robert Wong, vice-president and CIO of Toronto Hydro, all the big provincial utilities are subject to adhering to NERC CIP standards which have requirements for both cyber and physical security. Ontario is different from most provinces in that it has local distribution companies — like Toronto Hydro — which buy electricity in bulk and resell it to customers.  These LDCs don’t own or operate critical infrastructure and therefore don’t have to follow the NERC CIP standards.

Regional reforms, such as regulatory changes in Atlantic Canada, aim to bring greener power options to the grid.

Electricity is considered around the world as one of a country’s critical national infrastructure. Threats to the grid can be used for ransom or by a country for political pressure. Ukraine had its power network knocked offline in 2015 and 2016 by what were believed to be Russian-linked attackers operating against utilities.

All the big provincial utilities operate “critical infrastructure” and are subject to adhering to NERC CIP (critical infrastructure protection) standards, which have requirements for both cyber and physical security, as similar compromises at U.S. electric utilities have highlighted recently.  There are audited on a regular basis for compliance and can face hefty fines if they fail to meet the requirements.  The LDCs in Ontario don’t own or operate “critical infrastructure” and therefore are not required to adopt NERC CIP standards (at least for now).

The CIO Strategy Council is a forum for chief information officers that is helping set standards in a number of areas. In January it announced a partnership with the Internet Society’s Canada Chapter to create standards of practice for IoT security for consumer devices. As part of the federal government’s updated national cybersecurity strategy it is also developing a national cybersecurity standard for small and medium-sized businesses. That strategy would allow SMBs to advertise to customers that they meet minimum security requirements.

“The security of Canadians and our critical infrastructure is paramount,” federal minister of natural resources Seamus O’Regan said in a statement with today’s announcement. “Cyber attacks are becoming more common and dangerous. That’s why we are supporting this innovative project to protect the Canadian electricity sector.”

The announcement was welcomed by Robert Wong, Toronto Hydro’s vice-president and CIO. “Any additional investment towards strengthening the safeguards against cyberattacks to Canada’s critical infrastructure is definitely good news.  From the perspective of the electricity sector, the convergence of IT and OT (operational technology) has been happening for some time now as the traditional electricity grid has been transforming into a Smart Grid with the introduction of smart meters, SCADA systems, electronic sensors and monitors, smart relays, intelligent automated switching capabilities, distributed energy resources, and storage technologies (batteries, flywheels, compressed air, etc.).

“In my experience, many OT device and system manufacturers and vendors are still lagging the traditional IT vendors in incorporating Security by Design philosophies and effective security features into their products.  This, in turn, creates greater risks and challenges for utilities to protecting their critical infrastructures and ensuring a reliable supply of electricity to its customers.”

The Ontario Energy Board, which regulates the industry in the province, has led an initiative for all utilities to adopt the National Institute of Standards and Technology (NIST) Cybersecurity Framework, along with the ES-C2M2 maturity and Privacy By Design models, he noted.  Toronto Hydro has been managing its cybersecurity practice in adherence to these standards, as the city addresses growing electricity needs as well, he said.

“Other jurisdictions, such as Israel, have invested heavily on a national level in developing its cybersecurity capabilities and are seen as global leaders.  I am confident that given the availability of talent, capabilities and resources in Canada (especially around the GTA) if we get strong support and leadership at a federal level we can also emerge as a leader in this area as well.”

COVID-19 Response: Electric Power Industry Closely Coordinating With Federal Partners

ESCC COVID-19 Response coordinates utilities, public power, and cooperatives to protect the energy grid and electricity reliability, aligning with DOE, DHS, CDC, FERC, and NERC on continuity of operations, mutual assistance, and supply chain resilience.

 

Key Points

An industry government effort ensuring reliability, operations continuity and supply chain stability during COVID-19.

✅ Twice weekly ESCC calls align DOE, DHS, HHS, CDC, FERC, NERC priorities.

✅ Focus on control centers, generation, quarantine access, mutual aid.

✅ Resource Guide supports localized decisions and supply chain resilience.

 

The nation’s investor-owned electric companies, public power utilities, and electric cooperatives are working together to protect the energy grid as the U.S. grid addresses COVID-19 challenges and ensure continued access to safe and reliable electricity during the COVID-19 global health crisis.

The electric power industry has been planning for years, including extensive disaster planning across utilities, for an emergency like the COVID-19 pandemic, as well as countless other types of emergencies, and the industry is coordinating closely with government partners through the Electricity Subsector Coordinating Council (ESCC) to ensure that organizations have the resources they need to keep the lights on.

The ESCC is holding high-level coordination calls twice a week with senior leadership from the Departments of Energy, Homeland Security, and Health and Human Services, the Centers for Disease Control and Prevention, the Federal Energy Regulatory Commission, and the North American Electric Reliability Corporation. These calls help ensure that industry and government work together to resolve any challenges that arise during this health emergency and that electricity remains safe for customers.

“Electricity and the energy grid are indispensable to our society, and one of our greatest strengths as an industry is our ability to convene and adapt quickly to changing circumstances and challenging events,” said Edison Electric Institute President Tom Kuhn. “Our industry plans for all types of contingencies, with examples such as local response planning, and strong industry-government coordination and cross-sector collaboration are critical to our planning and response. We appreciate the ongoing leadership and support of our government partners as we all respond to COVID-19 and power through this crisis together.”

The ESCC quickly mobilized and established strategic working groups dedicated to identifying and solving for short-, medium-, and long-term issues facing the industry during the COVID-19 pandemic, with utilities implementing necessary precautions to maintain service across regions.

The five current areas of focus are:

1. Continuity of operations at control centers, including on-site staff lockdowns when needed
2. Continuity of operations at generation facilities
3. Access to, and operations in, restricted or quarantined areas
4. Protocols for mutual assistance
5. Supply chain challenges

“The electric power industry has taken steps to prepare for the evolving coronavirus challenges, while maintaining our commitment to the communities we serve, including customer relief efforts announced by some providers,” said National Rural Electric Cooperative Association CEO Jim Matheson. “We have a strong track record of preparing for many kinds of emergencies that could impact the ability to generate and deliver electricity. While planning for this situation is unique from other business continuity planning, we are taking actions to prepare to operate with a smaller workforce, potential disruptions in the supply chain, and limited support services for an extended period of time.”

The ESCC has developed a COVID-19 Resource Guide linked here and available at electricitysubsector.org. This document was designed to support electric power industry leaders in making informed localized decisions in response to this evolving health crisis. The guide will evolve as additional recommended practices are identified and as more is learned about appropriate mitigation strategies.

“The American Public Power Association (APPA) continues to work with our communityowned public power members and our industry and government partners to gather and share upto-date information, best practices, and guidance to support them in safely maintaining operational integrity,” said APPA CEO Joy Ditto.
