People living in the shadow of a group of wind turbines in Summerside, P.E.I., are complaining about the flickering light caused by the energy producers.

Emmett Curley has enjoyed living in the area for 15 years, but says things have become unbearable since the wind turbines arrived a year ago.

"Last summer when it started, I left my house. I just couldn't stand it. I've had friends over that left during the situation, saying, 'I'm starting to get a headache,'" Curley said.

The problem comes when the sun sets and its light passes through the turbines, creating a flickering effect of shadow and light. It lasts for about an hour.

"I'm lined up with two turbines that give me a double flicker. You can't watch TV, you can't read a book, a newspaper, you can't work on a computer because your eyes are constantly adjusting to light and dark," he said. "Green energy is a great thing, but when it interferes with life, health — no, something has to be done."

Other neighbours also said they were annoyed by the flickering. One told CBC News that her daughter feels sick to her stomach when it happens and the family has to spend part of their summer evenings in the basement.

Most want the city to shut the turbines off for the hour at sunset when the flicker happens, but the city said that is unlikely.

Greg Gaudet of Summerside Municipal Services said the city could provide options such as shutters or awnings for area residents.

He said shutting down the turbines for an hour each day would cost about $100,000 in lost energy over the course of a year.

"Obviously the city doesn't want to invest a large amount of money to create renewable energy, which is good for the environment, and then have to reduce those energies," he said.

"Obviously that's one of the last solutions the city would look at."

America’s Electricity is Safe From the Coronavirus—for Now

US Grid Pandemic Response coordinates control rooms, grid operators, and critical infrastructure, leveraging hydroelectric plants, backup control centers, mutual assistance networks, and deep cleaning protocols to maintain reliability amid reduced demand and COVID-19 risks.

 

Key Points

US Grid Pandemic Response encompasses measures by utilities and operators to safeguard power reliability during COVID-19

✅ Control rooms staffed on-site; operators split across backup centers

✅ Health screenings, deep cleaning, and isolation protocols mitigate contagion

✅ Reduced demand and mutual assistance improve grid resilience

 

Control rooms are the brains of NYPA’s power plants, which are mostly hydroelectric and supply about a quarter of all the electricity in New York state. They’re also a bit like human petri dishes. The control rooms are small, covered with frequently touched switches and surfaces, and occupied for hours on end by a half-dozen employees. Since social distancing and telecommuting isn’t an option in this context, NYPA has instituted regular health screenings and deep cleanings to keep the coronavirus out.

The problem is that each power plant relies on only a handful of control room operators. Since they have a specialized skill set, they can’t be easily replaced if they get sick. “They are very, very critical,” says Gil Quiniones, NYPA president and CEO. If the pandemic worsens, Quiniones says that NYPA may require control room operators to live on-site at power plants to reduce the chance of the virus making it in from the outside world. It sounds drastic, but Quiniones says NYPA has done it before during emergencies—once during the massive 2003 blackout, and again during Hurricane Sandy.

Meanwhile, PJM is one of North America’s nine regional grid operators and manages the transmission lines that move electricity from power plants to millions of customers in 13 states on the Eastern seaboard, including Washington, DC. PJM has had a pandemic response plan on the books for 15 years, but Mike Bryson, senior vice president of operations, says that this is the first time it’s gone into full effect. As of last week, about 80 percent of PJM’s 750 full-time employees have been working from home. But PJM also requires a skeleton crew of essential workers to be on-site at all times in its control centers. As part of its emergency planning, PJM built a backup control center years ago, and now it is splitting control center operators between the two to limit contact.

Past experience with large-scale disasters has helped the energy sector keep the lights on and ventilators running during the pandemic. Energy is one of 16 sectors that the US government has designated as “critical infrastructure,” which also includes the communications industry, transportation sector, and food and water systems. Each is seen as vital to the country and therefore has a duty to maintain operations during national emergencies.

“We need to be treated as first responders,” says Scott Aaronson, the vice president of security and preparedness at the Edison Electric Institute, a trade group representing private utilities. “Everybody's goal right now is to keep the public healthy, and to keep society functioning as best we can. A lack of electricity will certainly create a challenge for those goals.”

America’s electricity grid is a patchwork of regional grid operators connecting private and state-owned utilities. This means simply figuring out who’s in charge and coordinating among the various organizations is one of the biggest challenges to keeping the electricity flowing during a national emergency, according to Aaronson.

Generally, a lot of this responsibility falls on formal energy organizations like the nonprofit North American Electric Reliability Corporation and the Federal Energy Regulatory Commission. But during the coronavirus outbreak, an obscure organization run by the CEOs of electric utilities called the Electricity Subsector Coordinating Council has also served as a primary liaison between the federal government and the thousands of utility companies around the US. Aaronson says the organization has been meeting twice a week for the past three weeks to ensure that utilities are implementing best practices in their response to the coronavirus, as well as to inform the government of material needs to keep the energy sector running smoothly.

This tight-knit coordination will be especially important if the pandemic gets worse, as many forecasts suggest it will. Most utilities belong to at least one mutual assistance group, an informal network of electricity suppliers that help each other out during a catastrophe. These mutual assistance networks are usually called upon following major storms that threaten prolonged outages. But they could, in principle, be used to help during the coronavirus pandemic too. For example, if a utility finds itself without enough operators to manage a power plant, it could conceivably borrow trained operators from another company to make sure the power plant stays online.

So far, utilities and grid operators have managed to make it work on their own. There have been a handful of coronavirus cases reported at power plants, but they haven’t yet affected these plants’ ability to deliver energy. The challenges of running a power plant with a skeleton crew is partially offset by the reduced power demand as businesses shut down and more people work from home, says Robert Hebner, the director of the Center for Electromechanics at the University of Texas. “The reduced demand for power gives utilities a little breathing room,” says Hebner.

A recent study by the University of Chicago’s Energy Policy Institute found that electricity demand in Italy has plunged by 18 percent following the severe increase in coronavirus cases in the country. Energy demand in China also plummeted as a result of the pandemic. Bryson, at PJM, says the grid operator has seen about a 6 percent decrease in electricity demand in recent weeks, but expects an even greater drop if the pandemic gets worse.

Generally speaking, problems delivering electricity in the US occur when the grid is overloaded or physically damaged, such as during California wildfires or a hurricane.

An open question among coronavirus researchers is whether there will be a second wave of the pandemic later this year. During the Spanish flu pandemic in the early 20th century, the second wave turned out to be deadlier than the first. If the coronavirus remerges later this year, it could be a serious threat to reliable electricity in the US, says John MacWilliams, a former associate deputy secretary of the Department of Energy and a senior fellow at Columbia University’s Center on Global Energy Policy.

“If this crisis extends into the fall, we're going to hit hurricane season along the coasts,” MacWilliams says. “Utilities are doing a very good job right now, but if we get unlucky and have an active hurricane season, they're going to get very stressed because the number of workers that are available to repair damage and restore power will become more limited.”

This was a sentiment echoed by Bryson at PJM. “Any one disaster is manageable, but when you start layering them on top of each other, it gets much more challenging,” he adds. The US electricity grid struggles to handle major storms as it is, and these challenges will be heightened if too many workers are home sick. In this sense, the energy sector’s ability to deliver the electricity needed to keep manufacturing medical supplies or keep ventilators running depends to a large extent on our ability to flatten the curve today. The coronavirus is bad enough without having to worry about the lights going out.

COVID-19 closures: It's as if Ottawa has fallen off the electricity grid

Ontario Electricity Demand Drop During COVID-19 reflects a 1,000-2,000 MW decline as IESO balances the grid, shifts peak demand later, throttles generators and baseload nuclear, and manages exports amid changing load curves.

 

Key Points

An about 10% reduction in Ontario's load, shifting peaks and requiring IESO grid balancing measures.

✅ Demand down 1,000-2,000 MW; roughly 10% below normal.

✅ Peak shifts later in morning as home use rises.

✅ IESO throttles generators; baseload nuclear stays online.

 

It’s as if the COVID-19 epidemic had tripped a circuit breaker, shutting off all power to a city the size of Ottawa.

Virus-induced restrictions that have shut down large swaths of normal commercial life across Canada has led to a noticeable drop in demand for power in Ontario and reflect a global demand dip according to reports, insiders said on Friday.

Terry Young, vice-president with the Independent Electricity System Operator, said planning was underway for further declines in usage and for whether Ontario will embrace more clean power in the long term, given the delicate balance that needs to be maintained between supply and demand.

“We’re now seeing demand that is running about 1,000 to 2,000 megawatts less than we would normally see,” Young said. “You’re essentially seeing a city the size of Ottawa drop off demand during the day.”

At the high end, a 2,000 megawatt reduction would be close to the equivalent peak demand of Ottawa and London, Ont., combined.

The decline, in the order of 10 per cent from the 17,000 to 18,000 megawatts of usage that might normally be expected and similar to the UK’s 10% drop reported during lockdowns, began last week, Young said. The downward trend became more noticeable as governments and health authorities ordered non-essential businesses to close and people to stay home. However, residential and hospital usage has climbed.

Experts say frequent hand-washing and staying away from others is the most effective way to curb the spread of the highly contagious coronavirus, which poses a special risk to older people and those with underlying health conditions. As a result, factories and other big users have reduced production or closed entirely.

Because electricity cannot be stored, generators need to throttle back their output as domestic demand shrinks and exports to places such as the United States, including New York City, which is also being hit hard by the coronavirus, fall.

“We’re watching this carefully,” Young said. “We’re able to manage this drop, but it’s something we obviously have to keep watching…and making sure we’re not over-generating electricity.”

Turning off generation, especially for nuclear plants, is an intensive process, as are restarts and would likely happen only if the downward demand trend intensifies significantly, amid concerns over Ontario’s electricity getting dirtier if baseload is displaced. However, one of North America’s largest generators, Bruce Power near Kincardine, Ont., said it had a large degree of flexibility to scale down or up.

“We have the ability to provide one-third of our output as a dynamic response, which is unique to our facility,” said James Scongack, an executive vice-president with Bruce Power. “We developed this coming out of the 2008 downturn and it’s been a critical system asset for the last decade.”

“We don’t see there being a scenario where our baseload will not be needed,” he said, even as some warn Ontario may be short of electricity in the coming years.

The province’s publicly owned Ontario Power Generation said it was also in conversations with the system operator, which provides direction to generators, and is often cited in the Ontario election discussion.

One clear shift in normal work-day usage with so many people staying at home has been the change in demand patterns. Typically, Young said, there’s a peak from about 7 a.m. to 8 a.m. as people wake and get ready to go to work or school. The peak is now occurring later in the morning, Young said.

US Electricity Market Reforms could save Consumers $7bn

PJM and MISO Electricity-Market Reforms promise consumer savings by enabling renewables, wind, solar, and storage participation in wholesale markets, enhancing grid flexibility, reliability services, and real-time pricing across the Midwest, Great Lakes, and Mid-Atlantic.

 

Key Points

Market rule updates enabling renewables and storage, improving reliability and lowering consumer costs.

✅ Removes barriers to renewables, storage, demand response

✅ Improves intermarket links and real-time price signals

✅ Rewards flexible resources and reliability services

 

Electricity-market reforms to enable more renewables generation and storage in the Midwest, Great Lakes, and Mid-Atlantic could save consumers in the US and Canada more than $6.9 billion a year, according to a new report.

The findings may have major implications for consumer groups, large industrial companies, businesses, and homeowners in those regions, said the Wind-Solar Alliance, (WSA), which commissioned the Customer Focused and Clean report.

The WSA is a non-profit organisation supporting the growth of renewables. American Wind Energy Association CEO Tom Kiernan is listed as WSA secretary, amid ongoing debates about the US wind market today.

"Consumers are looking for clean energy, affordable and reliable energy that will keep their monthly electricity bills low," said Kristin Munsch, president of the Board of the Consumer Advocates of the PJM States, which represents over 65 million consumers in 13 states.

"There is great potential to achieve those goals with the cost-effective integration of wind, solar and battery storage plants into our wholesale power markets."

The report found the average residential customer in the PJM and Midcontinent Independent System Operator (MISO) regions, covering 29 US states and the Canadian province of Manitoba, could each save up to $48 a year as lower wholesale electricity prices materialize with significantly more wind, solar and storage on the grid.

The average annual home electricity, for example in New Jersey, in the PJM region, was just over $106 in 2018, according to the US Energy Information Administration.

The latest report quantifies the findings of a previous one for the WSA, published in November 2018, which found that outdated wholesale market rules in the US were preventing full participation by renewable energy, including wind power.

 

Outdated rules

"The existing wholesale power market rules were largely developed for slower-to-react conventional generators, such as coal and nuclear plants," said Michael Milligan, president of Milligan Grid Solutions and co-author of the new report.

"This report demonstrates the benefits of updating the rules to better accommodate the characteristics and potential contributions of wind and solar and other newer sources of low-cost generation."

With more renewables generation on the grid, customers would benefit the most from increasing power-system flexibility through market structures, the new report concluded. It called for the removal of artificial barriers preventing renewables, storage and demand response from participating in markets.

The report also advocated improving the connections between markets, thereby lowering transaction costs of imports and exports between neighbouring systems.

"There are currently artificial barriers that are preventing the full participation of renewables, storage and other new technologies in the PJM and MISO markets," said Michael Goggin, vice president of Grid Strategies and co-author of the report.

"Providing consumers with a real-time price signal that allows them to adjust their demand, rewarding flexible resources for their capabilities through improved market design, and allowing renewable and storage resources to participate in reliability-services markets would yield the greatest consumer benefits," he said.

PJM and MISO, which incorporate some of the windiest areas of the country, are currently reviewing their market designs as part of a broader grid overhaul underway.

Toronto Power Outages Persist for Hundreds After Spring Storm

Toronto Hydro Storm Outages continue after strong winds and heavy rain, with crews restoring power, clearing debris and downed lines. Safety alerts and real-time updates guide affected neighborhoods via website and social media.

 

Key Points

Toronto Hydro Storm Outages are weather-related power cuts; crews restore service safely and share public updates.

✅ Crews prioritize areas with severe damage and limited access

✅ Report downed power lines; keep a safe distance

✅ Check website and social media for restoration updates

 

In the aftermath of a powerful spring storm that swept through Toronto on Tuesday, approximately 400 customers remain without power as of Sunday. The storm, which brought strong winds and heavy rain that caused severe flooding in some areas, led to significant damage across the city, including downed trees and power lines. Toronto Hydro crews have been working tirelessly to restore service, similar to efforts by Sudbury Hydro crews in Northern Ontario, focusing on areas with the most severe damage. While many customers have had their power restored, the remaining outages are concentrated in neighborhoods where access is challenging due to debris and fallen infrastructure.

Toronto Hydro has assured residents that restoration efforts are ongoing and that they are prioritizing safety and efficiency, in step with recovery from damaging storms in Ontario across the province. The utility company has urged residents to report any downed power lines and to avoid approaching them, as they may still be live and dangerous, and notes that utilities sometimes rely on mutual aid deployments to speed restoration in large-scale events. Additionally, Toronto Hydro has been providing updates through their website and social media channels, keeping the public informed about the status of power restoration in affected areas.

The storm's impact has also led to disruptions in other services, and power outages in London disrupted morning routines for thousands earlier in the week. Some public transportation routes experienced delays due to debris on tracks, and several schools in the affected areas were temporarily closed. City officials are coordinating with various agencies to address these issues and ensure that services return to normal as quickly as possible, even as Quebec contends with widespread power outages after severe windstorms.

Residents are advised to stay updated on the situation through official channels and to exercise caution when traveling in storm-affected areas. Toronto Hydro continues to work diligently to restore power to all customers and appreciates the public's patience during this challenging time, a challenge echoed when Texas utilities struggled to restore power during Hurricane Harvey.

Ukraine Leans on Imports to Keep the Lights On

Ukraine Electricity Imports surge to record levels as EU neighbors bolster grid stability amid Russian strikes, supporting energy security, preventing blackouts, and straining cross-border transmission capacity while Ukraine rebuilds damaged infrastructure and diversifies with renewables.

 

Key Points

Emergency EU power purchases stabilizing Ukraine’s grid after war damage.

✅ Record 19,000 MWh per day from EU interconnectors

✅ Supports grid stability and blackout prevention

✅ Cost and transmission upgrades challenge sustainability

 

Russia's ongoing war in Ukraine has extended far beyond the battlefield, with critical infrastructure becoming a target. Ukraine's once-robust energy system has sustained significant damage amid energy ceasefire violations and Russian missile and drone strikes. To cope with these disruptions and maintain power supplies for Ukrainian citizens, the country is turning to record-breaking electricity imports from neighboring European nations.

Prior to the war, Ukraine enjoyed a self-sufficient energy sector, even exporting electricity to neighboring countries. However, targeted attacks on power plants and transmission lines have crippled generation capacity. The situation is particularly dire in eastern and southern Ukraine, where ongoing fighting has caused extensive damage.

Faced with this energy crisis, Ukraine is looking to Europe for a lifeline. The country's energy ministry has announced plans to import a staggering amount of electricity – exceeding 19,000 megawatt-hours (MWh) per day – to prepare for winter and stabilize supplies. This surpasses the previous record set in March 2024 and represents a significant increase in Ukraine's reliance on external power sources.

Several European nations are stepping up to support Ukraine. Countries like Poland, Slovakia, Romania, Hungary, which maintains quiet energy ties with Russia today, and Moldova have agreed to provide emergency electricity supplies. These imports will help stabilize Ukraine's power grid and prevent widespread blackouts, especially during peak consumption hours.

The reliance on imports, however, presents its own set of challenges. Firstly, the sheer volume of electricity needed puts a strain on the capacity of neighboring grids. Upgrading and expanding transmission infrastructure will be crucial to ensure a smooth flow of electricity. Secondly, the cost of imported electricity can be higher than domestically generated power amid price hikes and instability globally, placing additional pressure on Ukraine's already strained finances.

Beyond these immediate concerns, the long-term implications of relying on external energy sources need to be considered. Ukraine's long-term goal is to rebuild its own energy infrastructure and regain energy independence. International assistance, including energy security support measures, will be crucial in this endeavor. Financial aid and technical expertise can help Ukraine repair damaged power plants, diversify its energy mix through further investment in renewables, and develop more resilient grid infrastructure.

The war in Ukraine has underscored the importance of energy security. A nation's dependence on a single source of energy, be it domestic or foreign, leaves it vulnerable to disruption, as others consider national security and fossil fuels in their own policies. For Ukraine, diversification and building a more resilient energy infrastructure are key takeaways from this crisis.

The international community also has a role to play. Supporting Ukraine's energy sector not only helps the nation weather the current crisis but also strengthens European energy security as a whole, where concerns over Europe's energy nightmare remain pronounced. A stable and independent Ukraine, less reliant on Russian energy, contributes to a more secure and prosperous Europe.

As the war in Ukraine continues, the battle for energy security rages on. While the immediate focus is on keeping the lights on through imports, the long-term goal for Ukraine is to rebuild a stronger, more resilient energy sector that can power the nation's future. The international community's support will be crucial in helping Ukraine achieve this goal.

National Grid warns of short supply of electricity over next few days

National Grid power supply warning highlights electricity shortage risks amid low wind output, generator outages, and cold weather, reducing capacity margins and grid stability; considering demand response and reserve power to avoid blackout risk.

 

Key Points

An alert that reduced capacity from low wind and outages requires actions to maintain UK grid stability.

✅ Low wind output and generator outages reduce capacity margins

✅ ESO exploring demand response and reserve generation options

✅ Aim: maintain grid stability and avoid blackout risk

 

National Grid has warned that Britain’s electricity will be in short supply over the next few days after a string of unplanned power plant outages and unusually low wind speeds this week, as cheap wind power wanes across the system.

The electricity system operator said it will take action to “make sure there is enough generation” during the cold weather spell, including virtual power plants and other demand-side measures, to prevent a second major blackout in as many years.

“Unusually low wind output coinciding with a number of generator outages means the cushion of spare capacity we operate the system with has been reduced,” the company told its Twitter followers.

“We’re exploring measures and actions to make sure there is enough generation available to increase our buffer of capacity.”

A spokeswoman for National Grid said the latest electricity supply squeeze was not expected to be as severe as recorded last month, following reports that the government’s emergency energy plan was not going ahead, and added that the company did not expect to issue an official warning in the next 24 hours.

“We’re monitoring how the situation develops,” she said.

The warning is the second from the electricity system operator in recent weeks. In mid-September the company issued an official warning to the electricity market as peak power prices climbed, that its ‘buffer’ of power reserves had fallen below 500MW and it may need to call on more power plants to help prevent a blackout. The notice was later withdrawn.

Concerns over National Grid’s electricity supplies have been relatively rare in recent years. It was forced in November 2015 to ask businesses to cut their demand as a “last resort” measure to keep the lights on after a string of coal plant breakdowns.

But since then, National Grid’s greater challenge has been an oversupply of electricity, partly due to record wind generation, which has threatened to overwhelm the grid during times of low electricity demand.

National Grid has already spent almost £1bn on extra measures to prevent blackouts over the first half of the year by paying generators to produce less electricity during the coronavirus lockdown, as daily demand fell.

The company paid wind farms to turn off, and EDF Energy to halve the nuclear generation from its Sizewell B nuclear plant, to avoid overwhelming the grid when demand for electricity fell by almost a quarter from last year.

The electricity supply squeeze comes a little over a year after National Grid left large parts of England and Wales without electricity after the biggest blackout in a decade left a million homes in the dark. National Grid blamed a lightning strike for the widespread power failure.

Similar supply strains have recently caused power cuts in China, underscoring how weather and generation mix can trigger blackouts.
