Following the breakthrough production of 10 billion kilowatt-hours (kWh) in July 2008, power output of the Three Gorges Power Station, the largest hydropower station in the world, reached 11.3 billion kWh, a new record high, in August 2008.

This is equivalent to about 3.3% of the total power output in China during the period, China Three Gorges Project Corporation announced on September 5.

Runoff in the Yangtze River during this year's flood season has not been as severe as in previous years. So far, the maximum inlet flow of the Three Gorges Reservoir has been 41,000 cubic meters per second, which is 10,000 cubic meters per second less than the maximum flow of the same period last year.

The flow in the upstream of the Yangtze River was 25% less than the annual average in July this year. In August, the accumulated duration with a discharge of over 35,000 cubic meters per second was only six days.

Through optimal reservoir and power dispatching, water resources were fully utilized without any waste of water in peaking regulation. In July, power output of the project reached 10.3 billion kWh.

In August, all units of the project were basically kept on full load operation, the maximum daily and monthly power output reached 389 million kWh and 11.3 billion kWh, respectively, creating a record high since the first unit of the project began operation in July 2003.

As of September 5, the total installed operational capacity of the Three Gorges Power Station reached 17,600 megawatts. Twenty-five of the 26 units proposed in the preliminary design have been put into operation. The last unit is currently under general assembly and is expected to begin operation at the end of October or the beginning of November this year.

Opinion: The dilemma over electricity rates and innovation

Canadian Electricity Innovation drives a customer-centric, data-driven grid, integrating renewable energy, EVs, storage, and responsive loads to boost reliability, resilience, affordability, and sustainability while aligning regulators, utilities, and policy for decarbonization.

 

Key Points

A plan to modernize the grid, aligning utilities, regulators, and tech to deliver clean, reliable, affordable power.

✅ Smart grid supports EVs, storage, solar, and responsive loads.

✅ Innovation funding and regulatory alignment cut long-term costs.

✅ Resilience rises against extreme weather and outage risks.

 

For more than 100 years, Canadian electricity companies had a very simple mandate: provide reliable, safe power to all. Keep the lights on, as some would say. And they did just that.

Today, however, they are expected to also provide a broad range of energy services through a data-driven, customer-centric system operations platform that can manage, among other things, responsive loads, electric vehicles, storage devices and solar generation. All the while meeting environmental and social sustainability — and delivering on affordability.

Not an easy task, especially amid a looming electrical supply crunch that complicates planning.

That’s why this new mandate requires an ironclad commitment to innovation excellence. Not simply replacing “like with like,” or to make incremental progress, but to fundamentally reimagine our electricity system and how Canadians relate to it.

Our innovators in the electricity sector are stepping up to the plate and coming up with ingenious ideas, thanks to an annual investment of some $20 billion.

#google#

But they are presented with a dilemma.

Although Canada enjoys among the cleanest, most reliable electricity in the world, we have seen a sharp spike in its politicization. Electricity rates have become the rage and a top-of-mind issue for many Canadians, as highlighted by the Ontario hydro debate over rate plans. Ontario’s election reflects that passion.

This heightened attention places greater pressure on provincial governments, who regulate prices, and in jurisdictions like the Alberta electricity market questions about competition further influence those decisions. In turn, they delegate down to the actual regulators where, at their public hearings, the overwhelming and almost exclusive objective becomes: Keeping costs down.

Consequently, innovation pilot applications by Canadian electricity companies are routinely rejected by regulators, all in the name of cost constraints.

Clearly, electricity companies must be frugal and keep rates as low as possible.

No one likes paying more for their electricity. Homeowners don’t like it and neither do businesses.

Ironically, our rates are actually among the lowest in the world. But the mission of our political leaders should not be a race to the basement suite of prices. Nor should cheap gimmicks masquerade as serious policy solutions. Not if we are to be responsible to future generations.

We must therefore avoid, at all costs, building on the cheap.

Without constant innovation, reliability will suffer, especially as we battle more extreme weather events. In addition, we will not meet the future climate and clean energy targets such as the Clean Electricity Regulations for 2050 that all governments have set and continuously talk about. It is therefore incumbent upon our governments to spur a dynamic culture of innovation. And they must sync this with their regulators.

This year’s federal budget failed to build on the 2017 investments. One-time public-sector funding mechanisms are not enough. Investments must be sustained for the long haul.

To help promote and celebrate what happens when innovation is empowered by utilities, the Canadian Electricity Association has launched Canada’s first Centre of Excellence on electricity. The centre showcases cutting-edge development in how electricity is produced, delivered and consumed. Moreover, it highlights the economic, social and environmental benefits for Canadians.

One of the innovations celebrated by the centre was developed by Nova Scotia’s own NS Power. The company has been recognized for its groundbreaking Intelligent Feeder Project that generates power through a combination of a wind farm, a substation, and nearly a dozen Tesla batteries, reflecting broader clean grid and battery trends across Canada.

Political leaders must, of course, respond to the emotions and needs of their electors. But they must also lead.

That’s why ongoing long-term investments must be embedded in the policies of federal, provincial and territorial governments, and their respective regulatory systems. And Canada’s private sector cannot just point the finger to governments. They, too, must deliver, by incorporating meaningful innovation strategies into their corporate cultures and vision.

That’s the straightforward innovation challenge, as it is for the debate over rates.

But it also represents a generational opportunity, because if we get innovation right we will build that better, greener future that Canadians aspire to.

Sergio Marchi is president and CEO of the Canadian Electricity Association. He is a former Member of Parliament, cabinet minister, and Canadian Ambassador to the World Trade Organization and United Nations in Geneva.

Clocks are running slow across Europe because of an argument over who pays the electricity bill

European Grid Frequency Clock Slowdown has made appliance clocks run minutes behind as AC frequency drifts on the 50 Hz electricity grid, driven by a Kosovo-Serbia billing dispute and ENTSO-E monitored supply-demand imbalance.

 

Key Points

An EU-wide timing error where 50 Hz AC deviations slow appliance clocks due to Kosovo-Serbia grid imbalances.

✅ Clocks drifted up to six minutes across interconnected Europe

✅ Cause: unpaid power in N. Kosovo, contested by Serbia

✅ ENTSO-E reported 50 Hz deviations from supply-demand mismatch

 

Over the past couple of months, Europeans have noticed time slipping away from them. It’s not just their imaginations: all across the continent, clocks built into home appliances like ovens, microwaves, and coffee makers have been running up to six minutes slow. The unlikely cause? A dispute between Kosovo and Serbia over who pays the electricity bill.

To make sense of all this, you need to know that the clocks in many household devices use the frequency of electricity to keep time. Electric power is delivered to our homes in the form of an alternating current, where the direction of the flow of electricity switches back and forth many times a second. (How this system came to be established is complex, but the advantage is that it allows electricity to be transmitted efficiently.) In Europe, this frequency is 50 Hertz — meaning a current alternating of 50 times a second. In America, it’s 60 Hz, and during peak summer demand utilities often prepare for blackouts as heat drives loads higher.

Since the 1930s, manufacturers have taken advantage of this feature to keep time. Each clock needs a metronome — something with a consistent rhythm that helps space out each second — and an alternating current provides one, saving the cost of extra components. Customers simply set the time on their oven or microwave once, and the frequency keeps it precise.

At least, that’s the theory. But because this timekeeping method is reliant on electrical frequency, when the frequency changes, so do the clocks. That is what has been happening in Europe.

The news was announced this week by ENTSO-E, the agency that oversees the single, huge electricity grid connecting 25 European countries and which recently synchronized with Ukraine to bolster regional resilience. It said that variations in the frequency of the AC caused by imbalances between supply and demand on the grid have been messing with the clocks. The imbalance is itself caused by a political argument between Serbia and Kosovo. “This is a very sensitive dispute that materializes in the energy issues,” Susanne Nies, a spokesperson for ENTSO-E, told The Verge.

Essentially, after Kosovo declared independence from Serbia in 2008, there were long negotiations over custody of utilities like telecoms and electricity infrastructure. As part of the ongoing agreements (Serbia still does not recognize Kosovo as a sovereign state), four Serb-majority districts in the north of Kosovo stopped paying for electricity. Kosovo initially covered this by charging the rest of the country more, but last December, it decided it had had enough and stopped paying. This led to an imbalance: the Kosovan districts were still using electricity, but no one was paying to put it on the grid.

This might sound weird, but it’s because electricity grids work on a system of supply and demand, where surging consumption has even triggered a Nordic grid blockade in response to constrained flows. As Stewart Larque of the UK’s National Grid explains, you want to keep the same amount of electricity going onto the grid from power stations as the amount being taken off by homes and businesses. “Think of it like driving a car up a hill at a constant speed,” Larque told The Verge. “You need to carefully balance acceleration with gravity.” (The UK itself has not been affected by these variations because it runs its own grid.)

 

“THEY ARE FREE-RIDING ON THE SYSTEM.”

This balancing act is hugely complex and requires constant monitoring of supply and demand and communication between electricity companies across Europe, and growing cyber risks have spurred a renewed focus on protecting the U.S. power grid among operators worldwide. The dispute between Kosovo and Serbia, though, has put this system out of whack, as the two governments have been refusing to acknowledge what the other is doing.

“The Serbians [in Kosovo] have, according to our sources, not been paying for their electricity. So they are free-riding on the system,” says Nies.

The dispute came to a temporary resolution on Tuesday, when the Kosovan government stepped up to the plate and agreed to pay a fee of €1 million for the electricity used by the Serb-majority municipalities. “It is a temporary decision but as such saves our network functionality,” said Kosovo’s prime minister Ramush Haradinaj. In the longer term, though, a new agreement will need to be reached.

There have been rumors that the increase in demand from northern Kosovo was caused by cryptocurrency miners moving into the area to take advantage of the free electricity. But according to ENTSO-E, this is not the case. “It is absolutely unrelated to cryptocurrency,” Nies told The Verge. “There’s a lot of speculation about this, and it’s absolutely unrelated.” Representatives of Serbia’s power operator, EMS, refused to answer questions on this.

For now, “Kosovo is in balance again,” says Nies. “They are producing enough [electricity] to supply the population. The next step is to take the system back to normal, which will take several weeks.” In other words, time will return to normal for Europeans — if they remember to change their clocks, even as the U.S. power grid sees more blackouts than other developed nations.

Alberta set to retire coal power by 2023, ahead of 2030 provincial deadline

Alberta coal phaseout accelerates as utilities convert to natural gas, cutting emissions under TIER regulations and deploying hydrogen-ready, carbon capture capable plants, alongside new solar projects in a competitive, deregulated electricity market.

 

Key Points

A provincewide shift from coal to natural gas and renewables, cutting power emissions years ahead of the 2030 target.

✅ Capital Power, TransAlta converting coal units to gas

✅ TIER pricing drives efficiency, carbon capture readiness

✅ Hydrogen-ready turbines, solar projects boost renewables

 

Alberta is set to meet its goal to eliminate coal-fired electricity production years earlier than its 2030 target, amid a broader shift to cleaner energy in the province, thanks to recently announced utility conversion projects.

Capital Power Corp.’s plan to spend nearly $1 billion to switch two coal-fired power units west of Edmonton to natural gas, and stop using coal entirely by 2023, was welcomed by both the province and the Pembina Institute environmental think-tank.

In 2014, 55 per cent of Alberta’s electricity was produced from 18 coal-fired generators. The Alberta government announced in 2015 it would eliminate emissions from coal-fired electricity generation by 2030.

Dale Nally, associate minister of Natural Gas and Electricity, said Friday that decisions by Capital Power and other utilities to abandon coal will be good for the environment and demonstrates investor confidence in Alberta’s deregulated electricity market, where the power price cap has come under scrutiny.

He credited the government’s Technology Innovation and Emissions Reduction (TIER) regulations, which put a price on industrial greenhouse gas emissions, as a key factor in motivating the conversions.

“Capital Power’s transition to gas is a great example of how private industry is responding effectively to TIER, as it transitions these facilities to become carbon capture and hydrogen ready, which will drive future emissions reductions,” Nally said in an email.

Capital Power said direct carbon dioxide emissions at its Genesee power facility near Edmonton will be about 3.4 million tonnes per year lower than 2019 emission levels when the project is complete.

It says the natural gas combined cycle units it’s installing will be the most efficient in Canada, adding they will be capable of running on 30 per cent hydrogen initially, with the option to run on 95 per cent hydrogen in future with minor investments.

In November, Calgary-based TransAlta Corp. said it will end operations at its Highvale thermal coal mine west of Edmonton by the end of 2021 as it switches to natural gas at all of its operated coal-fired plants in Canada four years earlier than previously planned.

The Highvale surface coal mine is the largest in Canada, and has been in operation on the south shore of Wabamun Lake in Parkland County since 1970.

The moves by the two utilities and rival Atco Ltd., which announced three years ago it would convert to gas at all of its plants by this year, mean significant emissions reduction and better health for Albertans, said Binnu Jeyakumar, director of clean energy for Pembina.

“Alberta’s early coal phaseout is also a great lesson in good policy-making done in collaboration with industry and civil society,” she said.

“As we continue with this transformation of our electricity sector, it is paramount that efforts to support impacted workers and communities are undertaken.”

She added the growing cost-competitiveness of renewable energy, such as wind power, makes coal plant retirements possible, applauding Capital Power’s plans to increase its investments in solar power.

In Ontario, clean power policy remains a focus as the province evaluates its energy mix.

The company announced it would go ahead with its 75-megawatt Enchant Solar power project in southern Alberta, investing between $90 million and $100 million, and that it has signed a 25-year power purchase agreement with a Canadian company for its 40.5-MW Strathmore Solar project now under construction east of Calgary.

Garbage Truck Crash Knocks Down Power Poles in Little Haiti

Little Haiti Garbage Truck Power Outage in Miami after mechanical arms snagged power lines, snapping power poles; FPL crews, police, and businesses faced traffic delays, safety risks, and rapid restoration efforts across the neighborhood.

 

Key Points

A Miami incident where a garbage truck snagged power lines, toppling poles and causing outages and traffic delays.

✅ Mechanical arms caught overhead lines; three power poles snapped

✅ FPL dispatched, police directed traffic; restoration prioritized

✅ Dozens of businesses affected; afternoon rush hour congestion

 

On January 16, 2025, a significant incident unfolded in Miami's Little Haiti neighborhood when a garbage truck collided with power lines, causing three power poles to collapse and resulting in widespread power outages and traffic disruptions.

Incident Details

Around 1:30 p.m., a garbage truck traveling west on Northeast 82nd Street toward Interstate 95 became entangled with overhead power lines. The truck's mechanical arms caught the lines, leading to the snapping of three power poles and plunging the area into darkness, a scenario echoed by urban incidents like a manhole fire that left thousands without power. Witnesses reported a loud boom followed by an immediate power outage. One local business owner described the event, stating, "There was a loud boom, and suddenly the power went out."

Impact on the Community

The incident caused significant disruptions in the Little Haiti area. At least a dozen businesses were affected by the power outage, and in wider Florida events restoration can take weeks depending on damage, leading to operational halts and potential financial losses. The timing of the crash, during the afternoon rush hour, exacerbated traffic congestion as commuters were forced to navigate through the area, and similar disruptions occur when strong winds knock out power, further complicating the situation.

Response and Recovery Efforts

In response to the incident, Miami police directed traffic to alleviate congestion and ensure public safety. Florida Power & Light (FPL) crews, known for their major outage response, were promptly dispatched to the scene to assess the damage and begin restoration efforts. The priority was to safely remove the damaged power poles and restore electricity to the affected area. FPL's swift action was crucial in minimizing the duration of the power outage and restoring normalcy to the community.

Safety Considerations

This incident underscores the importance of safety protocols for vehicles operating in areas with overhead power lines. Garbage trucks, due to their design and operational mechanisms, are particularly susceptible to such accidents, and in broader disasters some regions require a power grid rebuild to recover, highlighting the stakes. It is imperative for operators to be vigilant and adhere to safety guidelines to prevent similar occurrences.

Community Resilience

Despite the challenges posed by the incident, the Little Haiti community demonstrated resilience. Local businesses and residents cooperated with authorities, while utilities elsewhere have restored power to thousands after major events, and the prompt response from emergency services highlighted the community's strength in the face of adversity.

Electricity Payouts on Biggest U.S. Grid Fall 64 Per Cent in Auction

PJM Capacity Auction Price Drop signals PJM Interconnection capacity market shifts, with $50/MW-day clearing, higher renewables and nuclear participation, declining coal, natural gas pressure, and zone impacts in ComEd and EMAAC, amid 21% reserve margins.

 

Key Points

A decline to $50 per MW-day in PJM capacity prices, shifting resource mix, zonal rates, and reserve margins.

✅ Clearing price fell to $50/MW-day from $140 in 2018

✅ Renewables and nuclear up; coal units down across PJM

✅ Zonal prices: ComEd $68.96, EMAAC $97.86; 21% reserves

 

Power-plant owners serving the biggest U.S. grid will be paid 64% less next year for being on standby to keep the lights on from New Jersey to Illinois.

Suppliers to PJM Interconnection LLC’s grid, which serves more than 65 million people, will get $50 a megawatt-day to provide capacity for the the year starting June 2022, according to the results of an auction released Wednesday. That’s down sharply from $140 in the previous auction, held in 2018. Analysts had expected the price would fall to about $85.

“Renewables, nuclear and new natural gas generators saw the greatest increases in cleared capacity, while coal units saw the largest decrease,” PJM said in a statement.

The PJM auction is the single most important event for power generators across the eastern U.S., including Calpine Corp., NRG Energy Inc. and Exelon Corp., because it dictates a big chunk of their future revenue. It also plays a pivotal role in shaping the region’s electricity mix, determining how much the region is willing to stick with coal and natural gas plants or replace them with wind and solar even as the aging grid complicates progress nationwide.

The results showed that the capacity price for the Chicago-area zone, known as ComEd, was $68.96 compared with $195.55 in the last auction. The price for the Pennsylvania and New Jersey zone, known as EMAAC, fell to $97.86 percent, from $165.73. All told, 144,477 megawatts cleared, representing a reserve margin of 21%.

Exelon shares fell 0.4% after the results were released. Vistra fell 1.5%. NRG was unchanged.

Blackouts triggered by extreme weather in Texas and California over the last year have reignited a debate over whether other regions should institute capacity systems similar to the one used by PJM, and whether to adopt measures like emergency fuel stock programs in New England as well. The market, which pays generators to be on standby in case extra power is needed, has long been a source of controversy. While it makes the grid more reliable, the system drives up costs for consumers. In the area around Chicago, for instance, these charges total more than $1.7 billion per year, accounting for 20% of customer bills, according to the Illinois Clean Jobs Coalition.

In the 2018 auction, PJM contracted supplies that were about 22% in excess of the peak demand projection at the time. This year, the grid is projected to start summer with a reserve margin of about 26%, as COVID-19 demand shifts persist, according to the market monitor -- far higher than the 16% most engineers say is needed to prevent major outages.

“This certainly doesn’t seem fair to ratepayers,” said Ari Peskoe, director of Harvard Law School’s Electricity Law Initiative.

Fossil-Fuel Advantage
Heading into the auction, analysts expected coal and gas plants to have the advantage. Nuclear reactors and renewables, they said, were poised to struggle amid coal and nuclear disruptions nationwide.

That’s because this is the first PJM auction run under a major pricing change imposed by federal regulators during the Trump administration. The new structure creates a price floor for some bidders, effectively hobbling nuclear and renewables that receive state subsidies while making it easier for fossil fuels to compete.

Those rules triggered contentious wrangling between power providers, PJM and federal regulators, delaying the auction for two years. The new system, however, may be short lived. The Biden administration is moving to overhaul the rules in time for the next auction in December.

Dominion Energy Inc., one of the biggest U.S. utility owners, pulled out of the market over the rules. The Virginia-based company, which has a goal to have net-zero carbon emissions by 2050, said the new PJM format will “make renewables more expensive” than delivering clean energy through alternative markets.

Illinois, New Jersey and Maryland have also threatened to leave the capacity market unless the new price floor is eliminated, and Connecticut is leading a market overhaul in New England as well. PJM has already launched a process to do it.

PJM is already one of the most fossil-fuel intensive grids, with 60% of its electricity coming from coal and gas. Power plants that bid into the auction rely on it for the bulk of their revenue. That means plants that win contracts have an incentive to continue operating for as long as they can, even amid a supply-chain crisis this summer.

Ontario Provides Stable Electricity Pricing for Industrial and Commercial Companies

Ontario ICI Electricity Pricing Freeze helps Industrial Conservation Initiative (ICI) participants by stabilizing Global Adjustment charges, suspending peak hours curtailment, and reducing COVID-19-related electricity cost volatility to support large employers returning operations to full capacity.

 

Key Points

A two-year policy stabilizing GA costs and pausing peak-hour cuts to aid industrial and commercial recovery.

✅ GA cost share frozen for two years

✅ No peak-hour curtailment obligations

✅ Supports industrial and commercial restart

 

The Ontario government is helping large industrial and commercial companies return to full levels of operation without the fear of electricity costs spiking by providing more stable electricity pricing for two years. Effective immediately, companies that participate in the Industrial Conservation Initiative (ICI) will not be required to reduce their electricity usage during peak hours or shift some load to ultra-low overnight pricing where applicable, as their proportion of Global Adjustment (GA) charges for these companies will be frozen.

"Ontario's industrial and commercial electricity consumers continue to experience unprecedented economic challenges during COVID-19, with electricity relief for households and small businesses introduced to help," said Greg Rickford, Minister of Energy, Northern Development and Mines. "Today's announcement will allow large industrial employers to focus on getting their operations up and running and employees back to work, instead of adjusting operations in response to peak electricity demand hours."

Due to COVID-19, electricity consumption in Ontario has been below average as fall in demand as people stayed home across the province, and the province is forecast to have a reliable supply of electricity, supported by the system operator's staffing contingency plans during the pandemic, to accommodate increased usage. Peak hours generally occur during the summer when the weather is hot and electricity demand from cooling systems is high.

"Today's action will reduce the burden of anticipating and responding to peak hours for more than 1,300 ICI participants with 2,000 primarily industrial facilities in Ontario," said Bill Walker, Associate Minister of Energy. "Now these large employers can focus on getting their operations back up and running at full tilt and explore new energy-efficiency programs to manage costs."

The government previously announced it was providing temporary relief for industrial and commercial electricity consumers that do not participate in the Regulated Price Plan (RPP) by deferring a portion of GA charges for April, May and June 2020 and by extending off-peak rates for many customers, as well as a disconnect moratorium extension for residential electricity users.
