An electrical equipment failure knocked out power recently in a handful of skyscrapers in Canada's financial center, leaving as many as 100,000 without electricity.

The downtown Toronto buildings affected included the tower that houses the offices of the Toronto Stock Exchange as well as First Canadian Place and the RBC Center, a Toronto Hydro spokesperson said.

Carolyn Quick, a spokeswoman for TMX Group Inc., which operates the Toronto Stock Exchange and the junior Venture market, said trading was uninterrupted.

"The Toronto Stock Exchange and TSX Venture Exchange continued to operate during the power outage as they are on separate power systems, as well as there is fully redundant system in place."

A tidal project in Scottish waters just generated enough electricity to power nearly 4,000 homes

MeyGen Tidal Stream Project delivers record 13.8 GWh to Scotland's grid, showcasing renewable ocean energy. Simec Atlantis Energy's 6 MW array of tidal turbines advances EU power goals and plans an ocean-powered data center.

 

Key Points

A Scottish tidal energy array exporting record power, using four 1.5 MW turbines and driving renewable innovation.

✅ Delivered 13.8 GWh to the grid in 2019, a project record.

✅ Four 1.5 MW turbines in Phase 1A, 6 MW installed.

✅ Plans include an ocean-powered data center near site.

 

A tidal power project in waters off the north coast of Scotland, where Scotland’s wind farms also deliver significant output, sent more than 13.8 gigawatt hours (GWh) of electricity to the grid last year, according to an operational update issued Monday. This figure – a record – almost doubled the previous high of 7.4 GWh in 2018.

In total, the MeyGen tidal stream array has now exported more than 25.5 GWh of electricity to the grid since the start of 2017, according to owners Simec Atlantis Energy. Phase 1A of the project is made up of four 1.5 megawatt (MW) turbines.

The 13.8 GWh of electricity exported in 2019 equates to the average yearly electricity consumption of roughly 3,800 “typical” homes in the U.K., where wind power records have been set recently, according to the company, with revenue generation amounting to £3.9 million ($5.09 million).

Onshore maintenance is now set to be carried out on the AR1500 turbine used by the scheme, with Atlantis aiming to redeploy the technology in spring.

In addition to the production of electricity, Atlantis is also planning to develop an “ocean-powered data centre” near the MeyGen project.

The European Commission has described “ocean energy” as being both abundant and renewable, and milestones like the biggest offshore windfarm starting U.K. supply underscore wider momentum, too. It’s estimated that ocean energy could potentially contribute roughly 10% of the European Union’s power demand by the year 2050, according to the Commission.

While tidal power has been around for decades — EDF’s 240 MW La Rance Tidal Power Plant in France was built as far back as 1966, and the country’s first offshore wind turbine has begun producing electricity — recent years have seen a number of new projects take shape.

In December last year, Scottish tidal energy business Nova Innovation was issued with a permit to develop a project in Nova Scotia, Canada, aiming to harness the Bay of Fundy tides in the region further.

In an announcement at the time, the firm said a total of 15 tidal stream turbines would be installed by the year 2023. The project, according to the firm, will produce enough electricity to power 600 homes, as companies like Sustainable Marine begin delivering tidal energy to the Nova Scotia grid.

Elsewhere, a business called Orbital Marine Power is developing what it describes as the world’s most powerful tidal turbine, with grid-supplied output already demonstrated.

The company says the turbine will have a swept area of more than 600 square meters and be able to generate “over 2 MW from tidal stream resources.” It will use a 72-meter-long “floating superstructure” to support two 1 MW turbines.

Ontario Sets Electricity Rates at Off-Peak Price until February 7

Ontario Off-Peak Electricity Rate offers 8.2 cents per kWh for 24 hours, supporting Time-of-Use and Tiered Regulated Price Plan customers, including residential, small business, and farms, under Ontario Energy Board guidelines during temporary relief.

 

Key Points

A temporary 8.2 cents per kWh all-day price for RPP customers, covering TOU and Tiered users across Ontario.

✅ Applies 24 hours daily at 8.2 cents per kWh for 21 days

✅ Covers residential, small business, and farm RPP customers

✅ Valid for TOU and Tiered plans set by the Ontario Energy Board

 

 The Ontario government has announced electricity relief with electricity prices set at the off-peak price of 8.2 cents per kilowatt-hour, 24 hours per day for 21 days starting January 18, 2022, until the end of day February 7, 2022, for all Regulated Price Plan customers. The off-peak rate will apply automatically to residential, small businesses and farms who pay Time-of-Use or Tiered prices set by the Ontario Energy Board.

This rate relief includes extended off-peak rates to support small businesses, as well as workers and families spending more time at home while the province is in Modified Step Two of the Roadmap to Reopen.

As part of our mandate, we set the rates that your utility charges for the electricity you use in your home or small business. These rates appear on the Electricity line of your bill, and we administer protections such as disconnection moratoriums for residential customers. We also set the Delivery rates that cover the cost to deliver electricity to most residential and small business customers.

 

Types of electricity rates

For residential and small business customers that buy electricity from their utility, there are two different types of rates (also called prices here), and Ontario also provides stable electricity pricing for larger users. The Ontario Energy Board sets both once a year on November 1:

Time-of-Use (TOU)

With TOU prices, the price depends on when you use electricity, including options like ultra-low overnight pricing that encourage off-peak use.

There are three TOU price periods:

  • Off-peak, when demand for electricity is lowest and new offerings like the Ultra-Low Overnight plan can encourage shifting usage. Ontario households use most of their electricity – nearly two thirds of it – during off-peak hours.
  • Mid-peak, when demand for electricity is moderate. These periods are during the daytime, but not the busiest times of day, and utilities like BC Hydro are exploring similar TOU structures as well.
  • On-peak, when demand for electricity is generally higher. These are the busier times of day – generally when people are cooking, starting up their computers and running heaters or air conditioners.

How Ukraine Will Keep the Lights On This Winter

Ukraine Winter Energy Strategy strengthens the power grid through infrastructure repairs, electricity imports, renewable integration, nuclear output, and conservation to ensure reliable heating, blackout mitigation, and grid resilience with international aid, generators, and transmission lines.

 

Key Points

A wartime plan to stabilize Ukraine's grid via repairs, imports, renewables, and nuclear to deliver reliable electricity.

✅ Repairs, imports, and demand management stabilize the grid.

✅ Renewables and nuclear reduce outage risks in winter.

✅ International aid supplies transformers, generators, expertise.

 

As Ukraine braces for the winter months, the question of how the country will keep the lights on has become a pressing concern, as the country fights to keep the lights on amid ongoing strikes. The ongoing war with Russia has severely disrupted Ukraine's energy infrastructure, leading to widespread damage to power plants, transmission lines, and other critical energy facilities. Despite these challenges, Ukraine has been working tirelessly to maintain its energy supply during the cold winter months, which are essential not only for heating but also for the functioning of homes, businesses, hospitals, and schools. Here's a closer look at the steps Ukraine is taking to keep the lights on this winter and ensure that its people have access to reliable electricity.

1. Repairing Damaged Infrastructure

One of the most immediate concerns for Ukraine's energy sector is the extensive damage inflicted on its power infrastructure by Russian missile and drone attacks. Since the war began in 2022, Ukraine has faced repeated attacks targeting power plants, substations, and power lines, including strikes on western regions that caused widespread outages across communities. These attacks have left parts of the country with intermittent or no electricity, and repairing the damage has been a monumental task.

However, Ukraine has made significant progress in restoring its energy infrastructure. Government agencies and energy companies have been working around the clock to repair power plants and transmission networks. Teams of technicians and engineers have been deployed to restore power to areas that have been hardest hit by Russian attacks, often under difficult and dangerous conditions. While some areas may continue to face outages, efforts to rebuild the energy grid are ongoing, with the government prioritizing critical infrastructure to ensure that hospitals, military facilities, and essential services have access to power.

2. Energy Efficiency and Conservation Measures

To cope with reduced energy availability and avoid overloading the grid, Ukrainian authorities have been encouraging energy efficiency and conservation measures. These efforts are particularly important during the winter when demand for electricity and heating is at its peak.

The government has implemented energy-saving programs, urging citizens and businesses to reduce their consumption and adopt new energy solutions that can be deployed quickly. Measures include limiting electricity use during peak hours, setting thermostats lower in homes and businesses, and encouraging the use of energy-efficient appliances. Ukrainian officials have also been promoting public awareness campaigns to educate people about the importance of energy conservation, which is crucial to avoid grid overload and ensure the distribution of power across the country.

3. Importing Energy from Abroad

To supplement domestic energy production, Ukraine has been working to secure electricity imports from neighboring countries. Ukraine has long been interconnected with energy grids in countries such as Poland, Slovakia, and Hungary, which allows it to import electricity during times of shortage. In recent months, Ukraine has ramped up efforts to strengthen these connections, ensuring that it can import electricity when domestic production is insufficient to meet demand, and in a notable instance, helped Spain during blackouts through coordinated cross-border support.

While electricity imports from neighboring countries provide a temporary solution, this is not without its challenges. The cost of importing electricity can be high, and the country’s ability to import large amounts of power depends on the availability of energy in neighboring nations; officials say there are electricity reserves and no scheduled outages if strikes do not resume. Ukraine has been actively seeking new energy partnerships and working with international organizations to secure access to electricity, including exploring the potential for importing energy from the European Union.

4. Harnessing Renewable Energy Sources

Another key part of Ukraine's strategy to keep the lights on this winter is tapping into renewable energy sources, particularly wind and solar power. While Ukraine’s energy sector has historically been dependent on fossil fuels, the country has been making strides in integrating renewable energy into its grid. Solar and wind energy are particularly useful in supplementing the national grid, especially during the winter months when demand is high.

Renewable energy sources are less vulnerable to missile strikes compared to traditional power plants, making them an attractive option for Ukraine's energy strategy. Although renewable energy currently represents a smaller portion of Ukraine’s overall energy mix, its contribution is expected to increase as the country invests more in clean energy infrastructure. In addition to reducing dependence on fossil fuels, this shift is aligned with Ukraine’s broader environmental goals and will be important for the long-term sustainability of its energy sector.

5. International Aid and Support

International support has been crucial in helping Ukraine keep the lights on during the war. Western allies, including the European Union and the United States, have provided financial assistance, technical expertise, and equipment to help restore the energy infrastructure, though Washington recently ended some grid restoration support as priorities shifted. In addition to rebuilding power plants and transmission lines, Ukraine has received advanced energy technologies and materials to strengthen its energy security.

The U.S. has sent electrical transformers, backup generators, and other essential equipment to help Ukraine restore its energy grid. The European Union has also provided both financial and technical assistance, supporting Ukraine’s efforts to integrate more renewable energy into its grid and enhancing the country’s ability to import electricity from neighboring states.

6. The Role of Nuclear Energy

Ukraine’s nuclear energy plants play a critical role in the country’s electricity supply. Before the war, nuclear power accounted for around 50% of Ukraine’s total electricity generation, and for communities near the front line, electricity is civilization that depends on reliable baseload. Despite the ongoing conflict, Ukrainian nuclear plants have remained operational, though they face heightened security risks due to the proximity of active combat zones.

In the winter months, nuclear plants are expected to continue providing a significant portion of Ukraine's electricity, which is essential for meeting the country's heating and power needs. The government has made efforts to ensure the safety and security of these plants, which remain a vital part of the country's energy strategy.

Keeping the lights on in Ukraine during the winter of 2024 is no small feat, given the war-related damage to energy infrastructure, rising energy demands, and ongoing security risks. However, the Ukrainian government has taken proactive steps to address these challenges, including repairing critical infrastructure, importing energy from neighboring countries, promoting energy efficiency, and expanding renewable energy sources. International aid and the continued operation of nuclear plants also play a vital role in ensuring a reliable energy supply. While challenges remain, Ukraine’s resilience and determination to overcome its energy crisis are clear, and the country is doing everything it can to keep the lights on through this difficult winter.

APS asks customers to conserve energy after recent blackouts in California

Arizona Energy Conservation Alert urges APS and TEP customers to curb usage during a heatwave, preventing rolling blackouts, easing peak demand, and supporting grid reliability by raising thermostats, delaying appliances, and pausing pool pumps.

 

Key Points

A utility request during extreme heat to cut demand and protect grid reliability, helping prevent outages.

✅ Raise thermostats to 80 F or higher during peak hours

✅ Delay washers, dryers, dishwashers until after 8 p.m.

✅ Pause pool pumps; switch off nonessential lights and devices

 

After excessive heat forced rolling blackouts for thousands of people across California Friday and Saturday, Arizona Public Service Electric is asking customers to conserve energy this afternoon and evening.

“Given the extended heat wave in the western United States and climate-related grid risks that utilities are monitoring, APS is asking customers to conserve energy due to extreme energy demand that is driving usage higher throughout the region with today’s high temperatures,” APS said in a statement.

Tucson Electric Power has made a similar request of customers in its coverage area.


APS is asking customers to conserve energy in the following ways Tuesday until 8 p.m.:

  • Raise thermostat settings to no lower than 80 degrees.
  • Turn off extra lights and avoid use of discretionary major appliances such as clothes washers, dryers and dishwashers.
  • Avoid operation of pool pumps.

The request from APS also came just hours after Arizona Corporation Commission Chairman Bob Burns sent a letter to electric utilities under the commission's umbrella, like APS, to see if they are in good shape or anticipate any problems given looming shortages in California. He requested the companies respond by noon Friday.


"The whole plan is to take a look at the system early in the Summer," Burns said. "Early May we look at the system, make sure we're ready and able to serve the public throughout the entire heat cycle."

Burns told ABC15 the Summer Preparedness workshop with utilities took place in May and the regulated utilities reported they were well equipped to meet the anticipated peaks of the Summer, even as supply-chain pressures mount across the industry. Tuesday's letter to the electric companies seeks to see if they are still able to "adequately, safely and reliably" serve customers through the heatwave, or if what happened in California could take place here.

"With the activities that are occurring over in California, including tight grid conditions that have repeatedly tested operators, we just want to double check," Burns said.

An APS representative told ABC15 they have adequate supply and reserve and don't anticipate any problems.

However, the rolling blackouts in California also caught the attention of Commissioner Lea Marquez Peterson. She is calling on the chairman to hold an emergency meeting amid wildfire concerns across California and the region.

"The risk to Arizonans and the fact that energy could be interrupted, that we had some kind of rolling blackout like California would have, would be really a public health issue," Peterson said. "It could be life and death in some cases for vulnerable populations."

Sustaining U.S. Nuclear Power And Decarbonization

Existing Nuclear Reactor Lifetime Extension sustains carbon-free electricity, supports deep decarbonization, and advances net zero climate goals by preserving the US nuclear fleet, stabilizing the grid, and complementing advanced reactors.

 

Key Points

Extending licenses keeps carbon-free nuclear online, stabilizes grid, and accelerates decarbonization toward net zero.

✅ Preserves 24/7 carbon-free baseload to meet climate targets

✅ Avoids emissions and replacement costs from premature retirements

✅ Complements advanced reactors; reduces capital and material needs

 

Nuclear power is the single largest source of carbon-free energy in the United States and currently provides nearly 20 percent of the nation’s electrical demand. As a result, many analyses have investigated the potential of future nuclear energy contributions in addressing climate change and investing in carbon-free electricity across the sector. However, few assess the value of existing nuclear power reactors.

Research led by Pacific Northwest National Laboratory (PNNL) Earth scientist Son H. Kim, with the Joint Global Change Research Institute (JGCRI), a partnership between PNNL and the University of Maryland, has added insight to the scarce literature and is the first to evaluate nuclear energy for meeting deep decarbonization goals amid rising credit risks for nuclear power identified by Moody's. Kim sought to answer the question: How much do our existing nuclear reactors contribute to the mission of meeting the country’s climate goals, both now and if their operating licenses were extended?

As the world races to discover solutions for reaching net zero as part of the global energy transition now underway, Kim’s report quantifies the economic value of bringing the existing nuclear fleet into the year 2100. It outlines its significant contributions to limiting global warming.

Plants slated to close by 2050 could be among the most important players in a challenge requiring all available carbon-free technology solutions—emerging and existing—alongside renewable electricity in many regions, the report finds. New nuclear technology also has a part to play, and its contributions could be boosted by driving down construction costs.  

“Even modest reductions in capital costs could bring big climate benefits,” said Kim. “Significant effort has been incorporated into the design of advanced reactors to reduce the use of all materials in general, such as concrete and steel because that directly translates into reduced costs and carbon emissions.”

Nuclear power reactors face an uncertain future, and some utilities face investor pressure to release climate reports as well.
The nuclear power fleet in the United States consists of 93 operating reactors across 28 states. Most of these plants were constructed and deployed between 1970-1990. Half of the fleet has outlived its original operating license lifetime of 40 years. While most reactors have had their licenses renewed for an additional 20 years, and some for another 20, the total number of reactors that will receive a lifetime extension to operate a full 80 years from deployment is uncertain.

Other countries also rely on nuclear energy. In France, for example, nuclear energy provides 70 percent of the country’s power supply. They and other countries must also consider extending the lifetime, retiring, or building new, modern reactors while navigating Canadian climate policy implications for electricity grids. However, the U.S. faces the potential retirement of many reactors in a short period—this could have a far stronger impact than the staggered closures other countries may experience.

“Our existing nuclear power plants are aging, and with their current 60-year lifetimes, nearly all of them will be gone by 2050. It’s ironic. We have a net zero goal to reach by 2050, yet our single largest source of carbon-free electricity is at risk of closure, as seen in New Zealand's electricity transition debates,“ said Kim.

New EPA power plant rules will put carbon capture to the test

CCUS in the U.S. Power Sector drives investments as DOE grants, 45Q tax credits, and EPA carbon rules spur carbon capture, geologic storage, and utilization, while debates persist over costs, transparency, reliability, and emissions safeguards.

 

Key Points

CCUS captures CO2 from power plants for storage or use, backed by 45Q tax credits, DOE funding, and EPA carbon rules.

✅ DOE grants and 45Q credits aim to de-risk project economics.

✅ EPA rules may require capture rates to meet emissions limits.

✅ Transparency and MRV guard against tax credit abuse.

 

New public and private funding, including DOE $110M for CCUS announced recently, and expected strong federal power plant emissions reduction standards have accelerated electricity sector investments in carbon capture, utilization and storage,’ or CCUS, projects but some worry it is good money thrown after bad.

CCUS separates carbon from a fossil fuel-burning power plant’s exhaust through carbon capture methods for geologic storage or use in industrial and other applications, according to the Department of Energy. Fossil fuel industry giants like Calpine and Chevron are looking to take advantage of new federal tax credits and grant funding for CCUS to manage potentially high costs in meeting power plant performance requirements, amid growing investor pressure for climate reporting, including new rules, expected from EPA soon, on reducing greenhouse gas emissions from existing power plants.

Power companies have “ambitious plans” to add CCUS to power plants, estimated to cause 25% of U.S. CO2 emissions. As a result, the power sector “needs CCUS in its toolkit,” said DOE Office of Fossil Energy and Carbon Management Assistant Secretary Brad Crabtree. Successful pilots and demonstrations “will add to investor confidence and lead to more deployment” to provide dispatchable clean energy, including emerging CO2-to-electricity approaches for power system reliability after 2030,| he added.

But environmentalists and others insist potentially cost-prohibitive CCUS infrastructure, including CO2 storage hub initiatives, must still prove itself effective under rigorous and transparent federal oversight.

“The vast majority of long-term U.S. power sector needs can be met without fossil generation, and better options are being deployed and in development,” Sierra Club Senior Advisor, Strategic Research and Development, Jeremy Fisher, said, pointing to carbon-free electricity investments gaining momentum in the market. CCUS “may be needed, but without better guardrails, power sector abuses of federal funding could lead to increased emissions and stranded fossil assets,” he added.

New DOE CCUS project grants, an increased $85 per metric ton, or tonne, federal 45Q tax credit, and the forthcoming EPA power plant carbon rules and the federal coal plan will do for CCUS what similar policies did for renewables, advocates and opponents agreed. But controversial past CCUS performance and tax credit abuses must be avoided with transparent reporting requirements for CO2 capture, opponents added.
