The TTC received the first shipment of its new generation of energy-smart buses in December. The buses are diesel-electric hybrids, using energy captured during braking to power part of their ride.

Although BC Transit, Edmonton and Ottawa have committed for some units, the TTC believes it's the first transit company in Canada undertaking to create hybrids in its fleet. As the second-generation hybrids reach the streets, the TTC will retire its aging GM diesel buses. They are now up to 25 years old; a special maintenance program has kept them rolling well beyond the usual 15-year lifespan.

Cost: $734,000 for a hybrid, compared with $500,000 for diesel buses.

Specs: 12 metres long; 2.6 metres wide; 3.4 metres high; 15,000 kg. Weight

Environmental benefits:

37% less greenhouse gas emissions

30-50% less emissions of harmful particulates

30-50% less nitrous oxide emissions

40 tonnes less carbon dioxide output, per bus each year

3-5 decibel reduction in noise levels

20-30% less fuel use (TTC now buys 75 million litres annually)

Where to ride: More than 100 are already on duty, mostly running out of the TTC's Arrow Rd. garage, west of Highway 400 and south of Finch Ave.

What's different: They look a lot like their first-generation cousins. But the manufacturer, Daimler-owned Orion Bus, has redesigned the hybrid mounting on the bus roof for a sleeker look.

All hybrids are low-floor, which means riders board at curb height. A ramp is still needed to provide wheelchair access at curbside. Hybrids come with air conditioning and bike racks. Their interior features peripheral seating; there are fewer seats at the back, but riders have an easier time reaching the back to stand there.

Seating and capacity: The buses have 36 seats, with a "crushload" capacity of 53 people.

GO's bus fleet takes high road

GO Transit has ordered 22 double-deckers from Alexander Dennis Ltd. in Edinburgh, Scotland. The city of Ottawa has committed to buying three and might order as many as 100 more.

When:

GO will receive 12 buses this year, including four next month. They'll go into service in April. The GO board recently exercised its option to buy 10 more double-deckers, to be delivered next year.

Efficiencies:

GO would need 17 regular coaches to seat the same number of riders as 12 double-deckers. The bigger buses mean GO needs fewer drivers and spends less on Highway 407 tolls. "On a per-seat basis, this bus is cost-effective," said Allan Robinson, GO's director of equipment development.

Cost:

$10.8 million for the first 12; a more pricey $9.7 million for the second order of 10

Specs:

13 metres long; 2.5 metres wide and 4.3 metres high; will be equipped with bike racks eventually.

Where:

Will travel Highways 403 and 407 on routes from Oakville to Unionville. York University will be their main hub, with stops at Square One and Bramalea. Double-deckers are limited to select routes because they're too tall to fit through many city underpasses. GO's 407 Express service is the fastest growing segment of its ridership, increasing 13 per cent last year while carrying nearly 2.4 million riders.

Seating:

78 seats, 46 on the upper deck, 32 on the lower level, compared with 57 seats in a GO regular coach.

Covid-19 puts brake on Turkey’s solar sector

Turkey Net Metering Suspension freezes regulator reviews, stalling rooftop solar permits and grid interconnections amid COVID-19, pausing licensing workflows, EPC pipelines, and electricity bill credits that drive commercial and household prosumer adoption.

 

Key Points

A pause on technical reviews freezing net metering applications and slowing rooftop solar deployment in Turkey.

✅ Monthly technical committee meetings suspended indefinitely

✅ Rooftop solar permits and grid interconnections on hold

✅ EPC firms urge remote evaluations for transparency

 

The decision by the Turkish Energy Market Regulatory Authority to halt part of the system of processing net metering applications risks bringing the only vibrant segment of the nation’s solar industry to a grinding halt, a risk amplified as global renewables face Covid-19 disruptions across markets.

The regulator has suspended monthly meetings of the committee which makes technical evaluations of net metering applications, citing concerns about the spread of Covid-19, which has already seen U.S. utility-scale solar face delays this year.

The availability of electricity bill credits for net-metering-approved households which inject surplus power into the grid, similar to how British households can sell power back to energy firms, has seen the rooftop projects the scheme is typically associated with remain the only source of new solar generation capacity in Turkey of late.

However the energy regulator’s decision to suspend technical evaluation committee meetings until further notice has seen the largely online licensing process for new solar systems practically cease; by contrast, Berlin is being urged to remove PV barriers to keep projects moving.

The Turkish solar industry has claimed the move is unnecessary, with solar engineering, procurement and construction services businesses pointing out the committee could meet to evaluate projects remotely. It has been argued such a move would streamline the application process and make it more transparent, regardless of the current public health crisis.

 

Net metering 

Turkey introduced net metering for rooftop installations last May and pv magazine has reported the specifics of the scheme, amid debates like New England's grid upgrade costs over who pays.

National grid operator Teias confirmed recently the country added 109 MW of new solar capacity in the first quarter, most of it net-metered rooftop systems, even as Australian distributors warn excess solar can strain local networks.

Net metering has been particularly attractive to commercial electricity users because the owners of small and medium-sized businesses pay more for power, as solar reshapes electricity prices in Northern Europe, than either households or large scale industrial consumers.

Until the recent technical committee decision by the regulator, the chief obstacle to net metering adoption had been the nation’s economic travails. The Turkish lira has lost 14% of its value since January and around 36% over the last two years. The central bank has been using its foreign reserves to support state lenders and the lira but the national currency slipped near an all-time low on Friday and foreign analysts predict the central bank reserves could run dry in July.

The level of exports shipped last month was down 41% on April last year and imports fell 28% by the same comparison, further depressing the willingness of companies to make capital investments such as rooftop solar.

NRC Begins Special Inspection at River Bend Nuclear Power Plant

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

 

Key Points

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

✅ Evaluates failures of portable emergency diesel generators

✅ Reviews causal analyses and adequacy of corrective actions

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

 

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

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

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

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

U.S. power demand seen sliding 1% in 2023 on milder weather

EIA U.S. Power Outlook 2023-2024 forecasts lower electricity demand, softer wholesale prices, and faster renewable growth from solar and wind, with steady natural gas, reduced coal generation, slight nuclear gains, and ERCOT market moderation.

 

Key Points

An EIA forecast of a 2023 demand dip, 2024 rebound, lower prices, and a higher renewable share in the U.S. power mix.

✅ Demand dips to 4,000 billion kWh in 2023; rebounds in 2024.

✅ ERCOT on-peak prices average about $35/MWh versus $80/MWh in 2022.

✅ Renewables grow to 24% share; coal falls to 17%; nuclear edges up.

 

U.S. power consumption is expected to slip about 1% in 2023 from the previous year as milder weather slows usage from the record high hit in 2022, consistent with recent U.S. consumption trends observed over the past several years, the U.S. Energy Information Administration (EIA) said in its Short-Term Energy Outlook (STEO).

EIA projected that electricity demand is on track to slide to 4,000 billion kilowatt-hours (kWh) in 2023 from a historic high of 4,048 billion kilowatt-hours (kWh) in 2022, reflecting patterns seen during COVID-19 demand shifts in prior years, before rising to 4,062 billion kWh in 2024 as economic growth ramps up.

Less demand coupled with more electricity generation from cheap renewable power sources and lower natural gas prices is forecast to slash wholesale power prices this year, the EIA said.

The on-peak wholesale price at the North hub in Texas’ ERCOT power market is expected to average about $35 per megawatt-hour (MWh) in 2023 compared with an average of nearly $80/MWh in 2022 after the 2022 price surge in power markets.

As capacity for renewables like solar and wind ramp up and as natural gas prices ease amid the broader energy crisis pressures, the EIA said it expects coal-fired power generation to be 17% less in the spring of 2023 than in the spring of 2022.

Coal will provide an average of 17% of total U.S. generation this year, down from 20% last year, as utilities shift investments toward electricity delivery and away from new power production, the EIA said.

The share of total generation supplied by natural gas is seen remaining at about the same this year at 39%. The nuclear share of generation is seen rising slightly to 20% this year from 19% in 2022. Generation from renewable energy sources grows the most in the forecast, increasing to 24% this year from a share of 22% last year, even as residential electricity bills rose in 2022 across the U.S.

Ontario Extends Off-Peak Electricity Rates to Provide Relief for Families, Small Businesses and Farms

Ontario Off-Peak Electricity Rate Relief extends 8.5 cents/kWh pricing 24/7 for residential, small business, and farm customers, covering Time-Of-Use and tiered plans to stabilize utility bills during COVID-19 Stay-at-Home measures across Ontario.

 

Key Points

A province-wide 8.5 cents/kWh price applied 24/7 until Feb 22, 2021 for TOU and tiered users to reduce electricity bills

✅ 8.5 cents/kWh, applied 24/7 through Feb 22, 2021

✅ Available to TOU and tiered OEB-regulated customers

✅ Automatic on bills for homes, small businesses, farms

 

The Ontario government is once again extending electricity rate relief for families, small businesses and farms to support those spending more time at home while the province maintains the Stay-at-Home Order in the majority of public health regions. The government will continue to hold electricity prices to the off-peak rate of 8.5 cents per kilowatt-hour, compared with higher peak rates elsewhere in the day, until February 22, 2021. This lower rate is available 24 hours per day, seven days a week for Time-Of-Use and tiered customers.

"We know staying at home means using more electricity during the day when electricity prices are higher, that's why we are once again extending the off-peak electricity rate to provide households, small businesses and farms with stable and predictable electricity bills when they need it most," said Greg Rickford, Minister of Energy, Northern Development and Mines, Minister of Indigenous Affairs. "We thank Ontarians for continuing to follow regional Stay-at-Home orders to help stop the spread of COVID-19."

The off-peak rate came into effect January 1, 2021, providing families, farms and small businesses with immediate electricity rate relief, and for industrial and commercial companies, stable pricing initiatives have provided additional certainty. The off-peak rate will now be extended until the end of day February 22, 2021, for a total of 53 days of emergency rate relief. During this period, and alongside temporary disconnect moratoriums for residential customers, the off-peak price will continue to be automatically applied to electricity bills of all residential, small business, and farm customers who pay regulated rates set by the Ontario Energy Board and get a bill from a utility.

"We extend our thanks to the Ontario Energy Board and local distribution companies across the province, including Hydro One, for implementing this extended emergency rate relief and supporting Ontarians as they continue to work and learn from home," said Bill Walker, Associate Minister of Energy.

Quebec Hit by Widespread Power Outages Following Severe Windstorm

Quebec Windstorm 2025 disrupted Montreal and surrounding regions, triggering power outages, Hydro-Québec repairs, fallen trees, infrastructure damage, and transport delays, while emergency response and community resilience accelerated restoration and recovery efforts across the province.

 

Key Points

A severe April 29 windstorm with 100 km/h gusts caused outages, damage, and emergency recovery across Quebec.

✅ Gusts exceeded 100 km/h across Montreal and nearby regions

✅ Hydro-Québec restored power; crews cleared debris and lines

✅ Communities shared resources, shelters, and volunteer support

 

A powerful windstorm swept across Quebec on April 29, 2025, leaving tens of thousands of residents without electricity and causing significant damage to infrastructure. The storm's intensity disrupted daily life, leading to widespread outages across the province, fallen trees, and transportation delays.

Storm's Impact

The windstorm, characterized by gusts exceeding 100 km/h, struck various regions of Quebec, including Montreal and its surrounding areas. Hydro-Québec reported extensive power outages affecting numerous customers. The storm's ferocity led to the uprooting of trees, downing of power lines, and significant damage to buildings and vehicles.

Response and Recovery Efforts

In the aftermath, emergency services and utility companies mobilized to restore power and clear debris. Hydro-Québec crews worked tirelessly, much like Sudbury Hydro teams did in Ontario, to repair damaged infrastructure, while municipal authorities coordinated efforts to ensure public safety and facilitate the restoration process. Despite these efforts, some areas experienced prolonged outages, highlighting the storm's severity.

Community Resilience

Residents demonstrated remarkable resilience during the crisis. Many communities came together to support one another, as seen when Toronto neighborhoods rallied during lingering outages, sharing resources and providing assistance to those in need. Local shelters were set up to offer warmth and supplies to displaced individuals, and volunteers played a crucial role in the recovery process.

Lessons Learned

The storm underscored the importance of preparedness and infrastructure resilience, including vulnerabilities highlighted by a recent manhole fire affecting Hydro-Québec customers. In response, discussions have been initiated regarding the strengthening of power grids and the implementation of more robust emergency response strategies to mitigate the impact of future natural disasters.

As Quebec continues to recover, the collective efforts of its residents and emergency services serve as a testament to the province's strength and unity, even as similar strong-wind outages affect other regions, in the face of adversity.

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.
