Utility worker suffers burns from power line

Ottawa Electricity Consumption Drop reflects COVID-19 impacts, with Hydro Ottawa and IESO reporting 10-12% lower demand, delayed morning peaks, and shifted weekend peak to 4 p.m., alongside provincial time-of-use rate relief.

Key Points

A 10-12% decline in Ottawa's electricity demand during COVID-19, with later morning peaks and weekend peak at 4 p.m.

✅ Weekday demand down 11%; weekends down 10% vs April 2019.

✅ Morning peak delayed about 4 hours; 6 a.m. usage down 17%.

✅ Weekend peak moved from 7 p.m. to 4 p.m.; rate relief ongoing.

Ottawa residents may be spending more time at home, with residential electricity use up even as the city’s overall energy use has dropped during the COVID-19 pandemic.

Hydro Ottawa says there was a 10-to-11 per cent drop in electricity consumption in April, with the biggest decline in electricity usage happening early in the morning, a pattern echoed by BC Hydro findings in its province.

Statistics provided to CTV News Ottawa show average hourly energy consumption in the City of Ottawa dropped 11 per cent during weekdays, mirroring Manitoba Hydro trends reported during the pandemic, and a 10 per cent decline in electricity consumption on weekends.

The drop in energy consumption came as many businesses in Ottawa closed their doors due to the COVID-19 measures and physical distancing guidelines.

“Based on our internal analysis, when comparing April 2020 to April 2019, Hydro Ottawa observed a lower, flatter rise in energy use in the morning, with peak demand delayed by approximately four hours.” Hydro Ottawa said in a statement to CTV News Ottawa.

“Morning routines appear to have the largest difference in energy consumption, most likely as a result of a collective slower pace to start the day as people are staying home.”

Hydro Ottawa says overall, there was an 11 per cent average hourly reduction in energy use on weekdays in April 2020, compared to April 2019. The biggest difference was the 6 a.m. hour, with a 17 per cent decrease.

On weekends, the average electricity usage dropped 10 per cent in April, compared to April 2019. The biggest difference was between 7 a.m. and 8 a.m., with a 13 per cent drop in hydro usage.

Hydro Ottawa says weekday peak continues to be at 4 p.m., while on weekends the peak has shifted from 7 p.m. before the pandemic to 4 p.m. now, though Hydro One has not cut peak rates for self-isolating customers.

The Independent Electricity System Operator says across Ontario, there has been a 10 to 12 per cent drop in energy consumption during the pandemic, a trend reflected in province-wide demand data that is the equivalent to half the demand of Toronto.

The Ontario Government has provided emergency electricity rate relief during the COVID-19 pandemic. Residential and small business consumers on time-of-use pricing, and later ultra-low overnight options, will continue to pay one price no matter what time of day the electricity is consumed until the end of May.

Nuclear decarbonization leverages low-carbon electricity, process heat, and hydrogen from advanced reactors and SMRs to electrify industry, buildings, and transport, supporting net-zero strategies and grid flexibility alongside renewables with dispatchable baseload capacity.

Key Points

Nuclear decarbonization uses reactors to supply low-carbon power, heat, and hydrogen, cutting emissions across industry.

✅ Advanced reactors and SMRs enable high-temperature process heat

✅ Nuclear-powered electrolysis and HTSE produce low-carbon hydrogen

✅ District heating from reactors reduces pollution and coal use

By Dr Henri Paillere, Head of the Planning and Economics Studies Section of the IAEA

Decarbonising the power sector will not be sufficient to achieving net-zero emissions, with assessments indicating nuclear may be essential across sectors. We also need to decarbonise the non-power sectors - transport, buildings and industry - which represent 60% of emissions from the energy sector today. The way to do that is: electrification with low-carbon electricity as much as possible; using low-carbon heat sources; and using low-carbon fuels, including hydrogen, produced from clean electricity.
The International Energy Agency (IEA) says that: 'Almost half of the emissions reductions needed to reach net zero by 2050 will need to come from technologies that have not reached the market today.' So there is a need to innovate and push the research, development and deployment of technologies. That includes nuclear beyond electricity.

Today, most of the scenario projections see nuclear's role ONLY in the power sector, despite ongoing debates over whether nuclear power is in decline globally, but increased electrification will require more low-carbon electricity, so potentially more nuclear. Nuclear energy is also a source of low-carbon heat, and could also be used to produce low-carbon fuels such as hydrogen. This is a virtually untapped potential.

There is an opportunity for the nuclear energy sector - from advanced reactors, next-gen nuclear small modular reactors, and non-power applications - but it requires a level playing field, not only in terms of financing today's technologies, but also in terms of promoting innovation and supporting research up to market deployment. And of course technology readiness and economics will be key to their success.

On process heat and district heating, I would draw attention to the fact there have been decades of experience in nuclear district heating. Not well spread, but experience nonetheless, in Russia, Hungary and Switzerland. Last year, we had two new projects. One floating nuclear power plant in Russia (Akademik Lomonosov), which provides not only electricity but district heating to the region of Pevek where it is connected. And in China, the Haiyang nuclear power plant (AP1000 technology) has started delivering commercial district heating. In China, there is an additional motivation to reducing emissions, namely to cut air pollution because in northern China a lot of the heating in winter is provided by coal-fired boilers. By going nuclear with district heating they are therefore cutting down on this pollution and helping with reducing carbon emissions as well. And Poland is looking at high-temperature reactors to replace its fleet of coal-fired boilers and so that's a technology that could also be a game-changer on the industry side.

There have also been decades of research into the production of hydrogen using nuclear energy, but no real deployment. Now, from a climate point of view, there is a clear drive to find substitute fuels for the hydrocarbon fuels that we use today, and multiple new nuclear stations are seen by industry leaders as necessary to meet net-zero targets. In the near term, we will be able to produce hydrogen with electrolysis using low-carbon electricity, from renewables and nuclear. But the cheapest source of low-carbon power is from the long-term operation of existing nuclear power plants which, combined with their high capacity factors, can give the cheapest low-carbon hydrogen of all.

In the mid to long term, there is research on-going with processes that are more efficient than low-temperature electrolysis, which is high temperature steam electrolysis or thermal splitting of water. These may offer higher efficiencies and effectiveness but they also require advanced reactors that are still under development. Demonstration projects are being considered in several countries and we at the IAEA are developing a publication that looks into the business opportunities for nuclear production of hydrogen from existing reactors. In some countries, there is a need to boost the economics of the existing fleet, especially in the electricity systems where you have low or even negative market prices for electricity. So, we are looking at other products that have higher values to improve the competitiveness of existing nuclear power plants.

The future means not only looking at electricity, but also at industry and transport, and so integrated energy systems. Electricity will be the main workhorse of our global decarbonisation effort, but through heat and hydrogen. How you model this is the object of a lot of research work being done by different institutes and we at the IAEA are developing some modelling capabilities with the objective of optimising low-carbon emissions and overall costs.

This is just a picture of what the future might look like: a low-carbon power system with nuclear lightwater reactors (large reactors, small modular reactors and fast reactors) drawing on the green industrial revolution reactor waves in planning; solar, wind, anything that produces low-carbon electricity that can be used to electrify industry, transport, and the heating and cooling of buildings. But we know there is a need for high-temperature process steam that electricity cannot bring but which can be delivered directly by high-temperature reactors. And there are a number of ways of producing low-carbon hydrogen. The beauty of hydrogen is that it can be stored and it could possibly be injected into gas networks that could be run in the future on 100% hydrogen, and this could be converted back into electricity.

So, for decarbonising power, there are many options - nuclear, hydro, variable renewables, with renewables poised to surpass coal in global generation, and fossil with carbon capture and storage - and it's up to countries and industries to invest in the ones they prefer. We find that nuclear can actually reduce the overall cost of systems due to its dispatchability and the fact that variable renewables have a cost because of their intermittency. There is a need for appropriate market designs and the role of governments to encourage investments in nuclear.

Decarbonising other sectors will be as important as decarbonising electricity, from ways to produce low-carbon heat and low-carbon hydrogen. It's not so obvious who will be the clear winners, but I would say that since nuclear can produce all three low-carbon vectors - electricity, heat and hydrogen - it should have the advantage.
We at the IAEA will be organising a webinar next month with the IEA looking at long-term nuclear projections in a net-zero world, building on IAEA analysis on COVID-19 and low-carbon electricity insights. That will be our contribution from the point of view of nuclear to the IEA's special report on roadmaps to net zero that it will publish in May.

US SF6 Emissions Decline as NOAA analysis and EPA mitigation show progress, with atmospheric measurements and Greenhouse Gas Reporting verifying reductions from the electric power grid; sulfur hexafluoride's extreme global warming potential underscores inventory improvements.

Key Points

A documented drop in US sulfur hexafluoride emissions, confirmed by NOAA atmospheric data and EPA reporting reforms.

✅ NOAA towers and aircraft show 2007-2018 decline

✅ EPA reporting and utility mitigation narrowed inventory gaps

✅ Winter leaks and servicing signal further reduction options

A new NOAA analysis shows U.S. emissions of the super-potent greenhouse gas sulfur hexafluoride (SF6) have declined between 2007-2018, likely due to successful mitigation efforts by the Environmental Protection Agency (EPA) and the electric power industry, with attention to SF6 in the power industry across global markets. 

At the same time, significant disparities that existed previously between NOAA’s estimates, which are based on atmospheric measurements, and EPA’s estimates, which are based on a combination of reported emissions and industrial activity, have narrowed following the establishment of the EPA's Greenhouse Gas Reporting Program. The findings, published in the journal Atmospheric Chemistry and Physics, also suggest how additional emissions reductions might be achieved. 

SF6 is most commonly used as an electrical insulator in high-voltage equipment that transmits and distributes electricity, and its emissions have been increasing worldwide as electric power systems expand, even as regions hit milestones like California clean energy surpluses in recent years. Smaller amounts of SF6 are used in semiconductor manufacturing and in magnesium production. 

SF6 traps 25,000 times more heat than carbon dioxide over a 100-year time scale for equal amounts of emissions, and while CO2 emissions flatlined in 2019 globally, that comparison underscores the potency of SF6. That means a relatively small amount of the gas can have a significant impact on climate warming. Because of its extremely large global warming potential and long atmospheric lifetime, SF6 emissions will influence Earth’s climate for thousands of years.

In this study, researchers from NOAA’s Global Monitoring Laboratory, as record greenhouse gas concentrations drive demand for better data, working with colleagues at EPA, CIRES, and the University of Maryland, estimated U.S. SF6 emissions for the first time from atmospheric measurements collected at a network of tall towers and aircraft in NOAA’s Global Greenhouse Gas Reference Network. The researchers provided an estimate of SF6 emissions independent from the EPA’s estimate, which is based on reported SF6 emissions for some industrial facilities and on estimated SF6 emissions for others.

“We observed differences between our atmospheric estimates and the EPA’s activity-based estimates,” said study lead author Lei Hu, a Global Monitoring Laboratory researcher who was a CIRES scientist at the time of the study. “But by closely collaborating with the EPA, we were able to identify processes potentially responsible for a significant portion of this difference, highlighting ways to improve emission inventories and suggesting additional emission mitigation opportunities, such as forthcoming EPA carbon capture rules for power plants, in the future.” 

In the 1990s, the EPA launched voluntary partnerships with the electric power, where power-sector carbon emissions are falling as generation shifts, magnesium, and semiconductor industries to reduce SF6 emissions after the United States recognized that its emissions were significant. In 2011, large SF6 -emitting facilities were required to begin tracking and reporting their emissions under the EPA Greenhouse Gas Reporting Program. 

Hu and her colleagues documented a decline of about 60 percent in U.S. SF6 emissions between 2007-2018, amid global declines in coal-fired power in some years—equivalent to a reduction of between 6 and 20 million metric tons of CO2 emissions during that time period—likely due in part to the voluntary emission reduction partnerships and the EPA reporting requirement. A more modest declining trend has also been reported in the EPA’s national inventories submitted annually under the United Nations Framework Convention on Climate Change. 

Examining the differences between the NOAA and EPA independent estimates, the researchers found that the EPA’s past inventory analyses likely underestimated SF6 emissions from electrical power transmission and distribution facilities, and from a single SF6 production plant in Illinois. According to Hu, the research collaboration has likely improved the accuracy of the EPA inventories. The 2023 draft of the EPA’s U.S. Greenhouse Gas Emissions and Sinks: 1990-2021 used the results of this study to support revisions to its estimates of SF6 emissions from electrical transmission and distribution. 

The collaboration may also lead to improvements in the atmosphere-based estimates, helping NOAA identify how to expand or rework its network to better capture emitting industries or areas with significant emissions, according to Steve Montzka, senior scientist at GML and one of the paper’s authors.

Hu and her colleagues also found a seasonal variation in SF6 emissions from the atmosphere-based analysis, with higher emissions in winter than in summer. Industry representatives identified increased servicing of electrical power equipment in the southern states and leakage from aging brittle sealing materials in the equipment in northern states during winter as likely explanations for the enhanced wintertime emissions—findings that suggest opportunities for further emissions reductions.

“This is a great example of the future of greenhouse gas emission tracking, where inventory compilers and atmospheric scientists work together to better understand emissions and shed light on ways to further reduce them,” said Montzka.

California Blackouts expose grid reliability risks as PG&E deenergizes lines during high winds. Mandated solar and wind displace dispatchable natural gas, straining ISO load balancing, transmission maintenance, and battery storage planning amid escalating wildfire liability.

Key Points

California grid shutoffs stem from wildfire risk, renewables, and deferred transmission maintenance under mandates.

✅ PG&E deenergizes lines to reduce wildfire ignition during high winds.

✅ Mandated solar and wind displace dispatchable gas, raising balancing costs.

✅ Storage, reliability pricing, and grid upgrades are needed to stabilize supply.

California is again facing widespread blackouts this season. Politicians are scrambling to assign blame to Pacific Gas & Electric (PG&E) a heavily regulated utility that can only do what the politically appointed regulators say it can do. In recent years this has meant building a bunch of solar and wind projects, while decommissioning reliable sources of power and scrimping on power line maintenance and upgrades.

The blackouts are connected with the legal liability from old and improperly maintained power lines being blamed for sparking fires—in hopes that deenergizing the grid during high winds reduces the likelihood of fires. 

How did the land of Silicon Valley and Hollywood come to have developing world electricity?

California’s Democratic majority, from Gov. Gavin Newsom to the solidly progressive legislature, to the regulators they appoint, have demanded huge increases in renewable energy. Renewable electricity targets have been pushed up, and policymakers are weighing a revamp of electricity rates to clean the grid, with the state expected to reach a goal of 33% of its power from renewable sources, mostly solar and wind, by next year, and 60% of its electricity from renewables by 2030.

In 2018, 31% of the electricity Californians purchased at the retail level came from approved renewables. But when rooftop solar is added to the mix, about 34% of California’s electricity came from renewables in 2018. Solar photovoltaic (PV) systems installed “behind-the-meter” (BTM) displace utility-supplied generation, but still affect the grid at large, as electricity must be generated at the moment it is consumed. PV installations in California grew 20% from 2017 to 2018, benefiting from the state’s Self-Generation Incentive Program that offers hefty rebates through 2025, as well as a 30% federal tax credit.

Increasingly large amounts of periodic, renewable power comes at a price—the more there is, the more difficult it is to keep the power grid stable and energized. Since electricity must be consumed the instant it is generated, and because wind and solar produce what they will whenever they do, the rest of the grid’s power producers—mostly natural gas plants—have to make up any differences between supply and immediate demand. This load balancing is vital, because without it, the grid will crash and widespread blackouts will ensue.

California often produces a surplus of mandated solar and wind power, generated for 5 to 8 cents per kilowatt hour. This power displaces dispatchable power from natural gas, coal and nuclear plants, resulting in reliable power plants spending less time online and driving up electricity prices as the plants operate for fewer hours of the day. Subsidized and mandated solar power, along with a law passed in California in 2006 (SB 1638) that bans the renewal of coal-fired power contracts, has placed enormous economic pressure on the Western region’s coal power plants—among them, the nation’s largest, Navajo Generating Station. As these plants go off line, the Western power grid will become increasingly unstable. Eventually, the states that share their electric power in the Western Interconnect may have to act to either subsidize dispatchable power or place a value on reliability—something that was taken for granted in the growth of the America’s electrical system and its regulatory scheme.

California law regarding electricity explicitly states that “a violation of the Public Utilities Act is a crime” and that it is “…the intent of the Legislature to provide for the evolution of the ISO (California’s Independent System Operator—the entity that manages California’s grid) into a regional organization to promote the development of regional electricity transmission markets in the western states.” In other words, California expects to dictate how the Western grid operates.

One last note as to what drives much of California’s energy policy: politics. California State Senator Kevin de León (the author served with him in the State Assembly) drafted SB 350, the Clean Energy and Pollution Reduction Act. It became law in 2015. Sen. de León followed up with SB 100 in 2018, signed into law weeks before the 2018 election. SB 100 increased California’s renewable portfolio standard to 60% by 2030 and further requires all the state’s electricity to come from carbon-free sources by 2045, a capstone of the state’s climate policies that factor into the blackout debate.  

Sen. de León used his environmental credentials to burnish his run for the U.S. Senate against Sen. Dianne Feinstein, eventually capturing the endorsements of the California Democratic Party and billionaire environmentalist Tom Steyer, now running for president. Feinstein and de León advanced to the general in California’s jungle primary, where Feinstein won reelection 54.2% to 45.8%.

De León may have lost his race for the U.S. Senate, but his legacy will live on in increasingly unaffordable electricity and blackouts, not only in California, but in the rest of the Western United States—unless federal or state regulators begin to place a value on reliability. This could be done by requiring utility scale renewable power providers to guarantee dispatchable power, as policymakers try to avert a looming shortage of firm capacity, either through purchase agreements with thermal power plants or through the installation of giant and costly battery farms or other energy storage means.

Sycamore Energy Manitoba Hydro Lawsuit centers on alleged mismanagement of the solar rebate incentive program, project delays, inspection backlogs, and alleged customer interference, impacting renewable energy installations, contractors, and clean power investment across Manitoba.

Key Points

Claim alleging mismanagement of Manitoba's solar rebate, delays, and inducing customers to switch installers.

✅ Lawsuit alleges mismanaged solar rebate incentive program

✅ Delays in inspections left hundreds of projects incomplete

✅ Claims Hydro urged customers to switch installers for rebates

Sycamore Energy filed a statement of claim Monday in Manitoba Court of Queens Bench against Manitoba Hydro saying it badly mismanaged its Solar Energy Program, a dispute that comes as Canada's solar progress faces criticism nationwide.

The claim also noted the crown corporation caused significant financial and reputational damage to Sycamore Energy, echoing disputes like Ontario wind cancellation costs seen elsewhere.

The statement of claim says Manitoba Hydro was telling customers to find other companies to complete solar panel installations, even as Nova Scotia's solar charge debate has unfolded.

'I'm still waiting': dozens of Manitoba solar system installations in the queue under expired incentive program
This all comes after a pilot project was launched in the province in April 2016, which would allow people to apply for a rebate under the incentive program, while Saskatchewan adjusted solar credits in parallel, and the project would cover about 25 per cent of the installation costs.

The project ended in April 2018, but hundreds of approved projects had yet to be finished.

According to Manitoba Hydro, in November there were 252 approved projects awaiting completion by more than one contractor, and Sycamore Energy said it had about 100 of those projects, a dynamic seen as New England's solar growth strains grid upgrades in other regions.

At the time Sycamore Energy COO, Alex Stuart, blamed Manitoba Hydro for the delays, stating it took too long to get inspections after solar systems were installed.

Scott Powell, Manitoba Hydro’s director of corporate communications, said in November he disagreed with Sycamore Energy’s comments, even as Ontario moves to reintroduce renewables elsewhere.

In a news release, the company said it sold more installations under Manitoba Hydro’s Solar Energy Program compared to other companies and it was instrumental in helping set up standards for the program.

“Manitoba Hydro mismanaged the solar rebate program from the beginning. In the end, they targeted our company unfairly and unlawfully by inducing our customers to break their contracts with us. Manitoba Hydro told our customers they could get an extension to their rebate but only if they switched to different installers,” said Justin Phillips, CEO of Sycamore Energy in a news release.

“We would much rather be installing clean, effective solar power projects for our customers right now. The last thing we want to do is to be suing Manitoba Hydro, but we feel we have no choice. Their actions have cost us millions in lost business. They’ve also cost the province jobs, millions in private investment and a positive way forward to help combat climate change.”

Manitoba Hydro now has 20 days to respond to the action, and a recent Cornwall wind-farm ruling underscores the stakes.

When asked for a response from CTV News, a spokesperson for the Crown corporation said it hadn’t yet been made aware of the suit.

“If a statement of claim is filed and served, we’ll file a statement of defence in due course. As this matter is now apparently before the courts, we have no further comment,” the spokesperson said.

None of these allegations have been proven in court.
