What's the point of a nuclear regulator that can be bypassed when it proves inconvenient? Federal MPs unanimously voted to overrule Canada's nuclear watchdog last week. They said it was to protect the public. The real reason seems to be that they couldn't bear to break up their six-week Christmas holidays.
At issue is the federal Atomic Energy of Canada Ltd.'s Chalk River nuclear reactor. It uses weapons-grade uranium to produce medical isotopes. It's also 50 years old.
Only five plants in the world produce isotopes. Atomic Energy of Canada, or AECL, sells its output to MDS Nordion, a private company with a lock on the North American market.
So when AECL announced last month that it was shutting down its Chalk River reactor for safety reasons, there was some consternation in both the corporate and medical worlds.
The dispute between AECL and its regulator, the Canadian Nuclear Safety Commission, turns on the issue of backup power. The reactor is cooled by heavy water. The pumps circulating that water are run by electricity. As Brian McGee, AECL's chief nuclear officer, told MPs last week, if the pumps were to fail, the reactor could release radioactivity into the surroundings.
Last year, the regulator told AECL to connect backup power systems that could resist bombs or earthquakes. AECL agreed but didn't do it. When the regulatory commission found out, the jig was up.
Enter the politicians.
While isotope shortages are not a good thing, it has never been clear that the country faced a full-blown health crisis. There were scattered shortages. But as Health Minister Tony Clement conceded, they were not serious enough to cause the government to redirect the isotopes MDS Nordion was exporting abroad.
Indeed, the main casualty of the interruption was MDS Nordion, which saw its fourth quarter profits slashed by two-thirds.
Still, no politician wants to be implicated in a Yuletide health scandal.
Prime Minister Stephen Harper blamed the regulatory commission, which he suggested was a nest of Liberal hacks. (In fact the president of the commission, Linda Keen, is a career civil servant).
Meanwhile, AECL quietly fixed one of the reactor's two pumps. As McGee told MPs, it should take no more than 16 days of additional down time to fix the other.
And Keen said her commission would let AECL operate the reactor with just one pump connected, if the Crown corporation produced a plan to show it would be safe.
That process, she figured, would take about a week.
In short: no immediate health crisis; no need to rush. At most, it would have taken just over two weeks for AECL to meet the regulator's safety standards.
So why did MPs panic and pass a law letting AECL operate for 120 days without meeting safety standards?
I understand Harper's Conservatives. They suspect all regulators are Communists.
What I didn't understand, at first, were the opposition MPs. Why did they fall in line with Harper?
Vancouver NDP MP Libby Davies finally provided the answer. The Commons could wait a week and see if AECL managed to satisfy the regulator, she noted. But by then, MPs would be on holidays. If a real crisis did emerge, they'd have to come back to Ottawa.
Faced with that grisly option, all agreed that it was best to override safety. Anyway, what's the problem? As AECL's McGee noted, even if the reactor does rupture, workers and local residents will at worst be irradiated "within recognized guidelines."
Commercial Electric Tariffs explain utility rate structures, peak demand charges, kWh vs kW pricing, time-of-use periods, voltage, delivery, capacity ratchets, and riders, guiding facility managers in tariff analysis for accurate energy savings.
Key Points
Commercial electric tariffs define utility pricing for energy, demand, delivery, time-of-use periods, riders, and ratchet charges.
✅ Separate kWh charges from kW peak demand fees.
✅ Verify time-of-use windows and demand interval length.
✅ Review riders, capacity ratchets, and minimum demand clauses.
Especially during these tough economic times, as major changes to electric bills are debated in some states, facility executives who don’t understand how their power is priced have been disappointed when their energy projects failed to produce expected dollar savings. Here’s how not to be one of them.
Your electric rate is spelled out in a document called a “tariff” that can be downloaded from your utility’s web page. A tariff should clearly spell out the costs for each component that is part of your rate, reflecting cost allocation practices in your region. Don’t be surprised to learn that it contains a bunch of them. Unlike residential electric rates, commercial electric bills are not based solely on the quantity of kilowatt-hours (kWh) consumed in a billing period (in the United States, that’s a month). Instead, different rates may apply to how your power is supplied, how it is delivered via electricity delivery charges, when it was consumed, its voltage, how fast it was used (in kW), and other factors.
If a tariff’s lingo and word structure are too opaque, spend some time with a utility account rep to translate it. Many state utility commissions also have customer advocates that may assist as they explore new utility rate designs that affect customers. Alternatively, for a fee, facility managers can privately chat with an energy consultant.
Common mistakes
Many facility managers try to estimate savings based on an averaged electric rate, i.e., annual electric spend divided by annual kWh. However, in markets where electricity demand is flat, such a number may obscure the fastest rising cost component: monthly peak demand charges, measured in dollars per kW (or kilo-volt-amperes, kVA).
This charge is like a monthly speeding ticket, based solely on the highest speed you drove during that time. In some areas, peak demand charges now account for 30 to 60 percent of a facility’s annual electric spend. When projecting energy cost savings, failing to separately account for kW peak demand and kWh consumption may result in erroneous results, and a lot of questions from the C-suite.
How peak demand charges are calculated varies among utilities. Some base it on the highest average speed of use across one hour in a month, while others may use the highest average speed during a 15- or 30-minute period. Others may average several of the highest speeds within a defined time period (for example, 8 a.m. to 6 p.m. on weekdays). It is whatever your tariff says it is.
Because some power-consuming (or producing) devices, including those tied to smart home electricity networks, vary in their operation or abilities, they may save money on a few — but not all — of those rate components. If an equipment vendor calculates savings from its product by using an average electric rate, take pause. Tell the vendor to return after the proposal has been redone using tariff-based numbers.
When a vendor is the only person calculating potential savings from using a product, there’s also a built-in conflict of interest: The person profiting from an equipment sale should not also be the one calculating its expected financial return. Before signing any energy project contracts, it’s essential that someone independent of the deal reviews projected savings. That person (typically an energy or engineering consultant) should be quite familiar with your facility’s electric tariff, including any special provisions, riders, discounts, etc., that may pertain. When this doesn’t happen, savings often don’t occur as planned.
For example, some utilities add another form of demand charge, based on the highest kW in a year. It has various names: capacity, contract demand, or the generic term “ratchet charge.” Some utilities also have a minimum ratchet charge which may be based on a percent of a facility’s annual kW peak. It ensures collection of sufficient utility revenue to cover the cost of installed transmission and distribution even when a customer significantly cuts its peak demand.
California Rolling Blackouts expose grid reliability risks amid a heatwave, as CAISO curtails power while solar output fades at sunset, wind stalls, and scarce natural gas and nuclear capacity plus PG&E issues strain imports.
Key Points
Grid outages during heatwaves from low reserves, fading solar, weak wind, and limited firm capacity.
✅ Heatwave demand rose as solar output dropped at sunset
✅ Limited imports and gas, nuclear shortfalls cut reserves
✅ Policy, pricing, and maintenance gaps increased outage risk
Millions of Californians were denied electrical power and thus air conditioning during a heatwave, raising the risk of heatstroke and death, particularly among the elderly and sick.
The blackouts come at a time when people, particularly the elderly, are forced to remain indoors due to Covid-19, and as later heat waves would test the grid again statewide.
At first, the state’s electrical grid operator last night asked customers to voluntarily reduce electricity use. But after lapses in power supply pushed reserves to dangerous levels it declared a “Stage 3 emergency” cutting off power to people across the state at 6:30 pm.
The immediate reason for the black-outs was the failure of a 500-megawatt power plant and an out-of-service 750-megawatt unit not being available. “There is nothing nefarious going on here,” said a spokeswoman for California Independent System Operator (CAISO). “We are just trying to run the grid.”
But the underlying reasons that California is experiencing rolling black-outs for the second time in less than a year stem from the state’s climate policies, which California policymakers have justified as necessary to prevent deaths from heatwaves, and which it is increasingly exporting to Western states as a model.
In October, Pacific Gas and Electric cut off power to homes across California to avoid starting forest fires after reports that its power lines may have started fires in recent seasons. The utility and California’s leaders had over the previous decade diverted billions meant for grid maintenance to renewables.
And yesterday, California had to impose rolling blackouts because it had failed to maintain sufficient reliable power from natural gas and nuclear plants, or pay in advance for enough guaranteed electricity imports from other states.
It may be that California’s utilities and their regulator, the California Public Utilities Commission, which is also controlled by Gov. Newsom, didn’t want to spend the extra money to guarantee the additional electricity out of fears of raising California’s electricity prices even more than they had already raised them.
California saw its electricity prices rise six times more than the rest of the United States from 2011 to 2019, helping explain why electricity prices are soaring across the state, due to its huge expansion of renewables. Republicans in the U.S. Congress point to that massive increase to challenge justifications by Democrats to spend $2 trillion on renewables in the name of climate change.
Even though the cost of solar panels declined dramatically between 2011 and 2019, their unreliable and weather-dependent nature meant that they imposed large new costs in the form of storage and transmission to keep electricity as reliable. California’s solar panels and farms were all turning off as the blackouts began, with no help available from the states to the East already in nightfall.
Electricity from solar goes away at the very moment when the demand for electricity rises. “The peak demand was steady in late hours,” said the spokesperson for CAISO, which is controlled by Gov. Gavin Newsom, “and we had thousands of megawatts of solar reducing their output as the sunset.”
The two blackouts in less than a year are strong evidence that the tens of billions that Californians have spent on renewables come with high human, economic, and environmental costs.
Last December, a report by done for PG&E concluded that the utility’s customers could see blackouts double over the next 15 years and quadruple over the next 30.
California’s anti-nuclear policies also contributed to the blackouts. In 2013, Gov. Jerry Brown forced a nuclear power plant, San Onofre, in southern California to close.
Had San Onofre still been operating, there almost certainly would not have been blackouts on Friday as the reserve margin would have been significantly larger. The capacity of San Onofre was double that of the lost generation capacity that triggered the blackout.
California's current and former large nuclear plants are located on the coast, which allows for their electricity to travel shorter distances, and through less-constrained transmission lines than the state’s industrial solar farms, to get to the coastal cities where electricity is in highest demand.
There has been very little electricity from wind during the summer heatwave in California and the broader western U.S., further driving up demand. In fact, the same weather pattern, a stable high-pressure bubble, is the cause of heatwaves, since it brought very low wind for days on end along with very high temperatures.
Things won’t be any better, and may be worse, in the winter, with a looming shortage as it produces far less solar electricity than the summer. Solar plus storage, an expensive attempt to fix problems like what led to this blackout, cannot help through long winters of low output.
California’s electricity prices will continue to rise if it continues to add more renewables to its grid, and goes forward with plans to shut down its last nuclear plant, Diablo Canyon, in 2025.
Had California spent an estimated $100 billion on nuclear instead of on wind and solar, it would have had enough energy to replace all fossil fuels in its in-state electricity mix.
To manage the increasingly unreliable grid, California will either need to keep its nuclear plant operating, build more natural gas plants, underscoring its reliance on fossil fuels for reliability, or pay ever more money annually to reserve emergency electricity supplies from its neighbors.
After the blackouts last October, Gov. Newsom attacked PG&E Corp. for “greed and mismanagement” and named a top aide, Ana Matosantos, to be his “energy czar.”
“This is not the new normal, and this does not take 10 years to solve,” Newsom said. “The entire system needs to be reimagined.”
Boeing 787 More-Electric Architecture replaces pneumatics with bleedless pressurization, VFSG starter-generators, electric brakes, and heated wing anti-ice, leveraging APU, RAT, batteries, and airport ground power for efficient, redundant electrical power distribution.
Key Points
An integrated, bleedless electrical system powering start, pressurization, brakes, and anti-ice via VFSGs, APU and RAT.
✅ VFSGs start engines, then generate 235Vac variable-frequency power
✅ Bleedless pressurization, electric anti-ice improve fuel efficiency
✅ Electric brakes cut hydraulic weight and simplify maintenance
The 787 Dreamliner is different to most commercial aircraft flying the skies today. On the surface it may seem pretty similar to the likes of the 777 and A350, but get under the skin and it’s a whole different aircraft.
When Boeing designed the 787, in order to make it as fuel efficient as possible, it had to completely shake up the way some of the normal aircraft systems operated. Traditionally, systems such as the pressurization, engine start and wing anti-ice were powered by pneumatics. The wheel brakes were powered by the hydraulics. These essential systems required a lot of physical architecture and with that comes weight and maintenance. This got engineers thinking.
What if the brakes didn’t need the hydraulics? What if the engines could be started without the pneumatic system? What if the pressurisation system didn’t need bleed air from the engines? Imagine if all these systems could be powered electrically… so that’s what they did.
Power sources
The 787 uses a lot of electricity. Therefore, to keep up with the demand, it has a number of sources of power, much as grid operators track supply on the GB energy dashboard to balance loads. Depending on whether the aircraft is on the ground with its engines off or in the air with both engines running, different combinations of the power sources are used.
Engine starter/generators
The main source of power comes from four 235Vac variable frequency engine starter/generators (VFSGs). There are two of these in each engine. These function as electrically powered starter motors for the engine start, and once the engine is running, then act as engine driven generators.
The generators in the left engine are designated as L1 and L2, the two in the right engine are R1 and R2. They are connected to their respective engine gearbox to generate electrical power directly proportional to the engine speed. With the engines running, the generators provide electrical power to all the aircraft systems.
APU starter/generators
In the tail of most commercial aircraft sits a small engine, the Auxiliary Power Unit (APU). While this does not provide any power for aircraft propulsion, it does provide electrics for when the engines are not running.
The APU of the 787 has the same generators as each of the engines — two 235Vac VFSGs, designated L and R. They act as starter motors to get the APU going and once running, then act as generators. The power generated is once again directly proportional to the APU speed.
The APU not only provides power to the aircraft on the ground when the engines are switched off, but it can also provide power in flight should there be a problem with one of the engine generators.
Battery power
The aircraft has one main battery and one APU battery. The latter is quite basic, providing power to start the APU and for some of the external aircraft lighting.
The main battery is there to power the aircraft up when everything has been switched off and also in cases of extreme electrical failure in flight, and in the grid context, alternatives such as gravity power storage are being explored for long-duration resilience. It provides power to start the APU, acts as a back-up for the brakes and also feeds the captain’s flight instruments until the Ram Air Turbine deploys.
Ram air turbine (RAT) generator
When you need this, you’re really not having a great day. The RAT is a small propeller which automatically drops out of the underside of the aircraft in the event of a double engine failure (or when all three hydraulics system pressures are low). It can also be deployed manually by pressing a switch in the flight deck.
Once deployed into the airflow, the RAT spins up and turns the RAT generator. This provides enough electrical power to operate the captain’s flight instruments and other essentials items for communication, navigation and flight controls.
External power
Using the APU on the ground for electrics is fine, but they do tend to be quite noisy. Not great for airports wishing to keep their noise footprint down. To enable aircraft to be powered without the APU, most big airports will have a ground power system drawing from national grids, including output from facilities such as Barakah Unit 1 as part of the mix. Large cables from the airport power supply connect 115Vac to the aircraft and allow pilots to shut down the APU. This not only keeps the noise down but also saves on the fuel which the APU would use.
The 787 has three external power inputs — two at the front and one at the rear. The forward system is used to power systems required for ground operations such as lighting, cargo door operation and some cabin systems. If only one forward power source is connected, only very limited functions will be available.
The aft external power is only used when the ground power is required for engine start.
Circuit breakers
Most flight decks you visit will have the back wall covered in circuit breakers — CBs. If there is a problem with a system, the circuit breaker may “pop” to preserve the aircraft electrical system. If a particular system is not working, part of the engineers procedure may require them to pull and “collar” a CB — placing a small ring around the CB to stop it from being pushed back in. However, on the 787 there are no physical circuit breakers. You’ve guessed it, they’re electric.
Within the Multi Function Display screen is the Circuit Breaker Indication and Control (CBIC). From here, engineers and pilots are able to access all the “CBs” which would normally be on the back wall of the flight deck. If an operational procedure requires it, engineers are able to electrically pull and collar a CB giving the same result as a conventional CB.
Not only does this mean that the there are no physical CBs which may need replacing, it also creates space behind the flight deck which can be utilised for the galley area and cabin.
A normal flight
While it’s useful to have all these systems, they are never all used at the same time, and, as the power sector’s COVID-19 mitigation strategies showed, resilience planning matters across operations. Depending on the stage of the flight, different power sources will be used, sometimes in conjunction with others, to supply the required power.
On the ground
When we arrive at the aircraft, more often than not the aircraft is plugged into the external power with the APU off. Electricity is the blood of the 787 and it doesn’t like to be without a good supply constantly pumping through its system, and, as seen in NYC electric rhythms during COVID-19, demand patterns can shift quickly. Ground staff will connect two forward external power sources, as this enables us to operate the maximum number of systems as we prepare the aircraft for departure.
Whilst connected to the external source, there is not enough power to run the air conditioning system. As a result, whilst the APU is off, air conditioning is provided by Preconditioned Air (PCA) units on the ground. These connect to the aircraft by a pipe and pump cool air into the cabin to keep the temperature at a comfortable level.
APU start
As we near departure time, we need to start making some changes to the configuration of the electrical system. Before we can push back , the external power needs to be disconnected — the airports don’t take too kindly to us taking their cables with us — and since that supply ultimately comes from the grid, projects like the Bruce Power upgrade increase available capacity during peaks, but we need to generate our own power before we start the engines so to do this, we use the APU.
The APU, like any engine, takes a little time to start up, around 90 seconds or so. If you remember from before, the external power only supplies 115Vac whereas the two VFSGs in the APU each provide 235Vac. As a result, as soon as the APU is running, it automatically takes over the running of the electrical systems. The ground staff are then clear to disconnect the ground power.
If you read my article on how the 787 is pressurised, you’ll know that it’s powered by the electrical system. As soon as the APU is supplying the electricity, there is enough power to run the aircraft air conditioning. The PCA can then be removed.
Engine start
Once all doors and hatches are closed, external cables and pipes have been removed and the APU is running, we’re ready to push back from the gate and start our engines. Both engines are normally started at the same time, unless the outside air temperature is below 5°C.
On other aircraft types, the engines require high pressure air from the APU to turn the starter in the engine. This requires a lot of power from the APU and is also quite noisy. On the 787, the engine start is entirely electrical.
Power is drawn from the APU and feeds the VFSGs in the engines. If you remember from earlier, these fist act as starter motors. The starter motor starts the turn the turbines in the middle of the engine. These in turn start to turn the forward stages of the engine. Once there is enough airflow through the engine, and the fuel is igniting, there is enough energy to continue running itself.
After start
Once the engine is running, the VFSGs stop acting as starter motors and revert to acting as generators. As these generators are the preferred power source, they automatically take over the running of the electrical systems from the APU, which can then be switched off. The aircraft is now in the desired configuration for flight, with the 4 VFSGs in both engines providing all the power the aircraft needs.
As the aircraft moves away towards the runway, another electrically powered system is used — the brakes. On other aircraft types, the brakes are powered by the hydraulics system. This requires extra pipe work and the associated weight that goes with that. Hydraulically powered brake units can also be time consuming to replace.
By having electric brakes, the 787 is able to reduce the weight of the hydraulics system and it also makes it easier to change brake units. “Plug in and play” brakes are far quicker to change, keeping maintenance costs down and reducing flight delays.
In-flight
Another system which is powered electrically on the 787 is the anti-ice system. As aircraft fly though clouds in cold temperatures, ice can build up along the leading edge of the wing. As this reduces the efficiency of the the wing, we need to get rid of this.
Other aircraft types use hot air from the engines to melt it. On the 787, we have electrically powered pads along the leading edge which heat up to melt the ice.
Not only does this keep more power in the engines, but it also reduces the drag created as the hot air leaves the structure of the wing. A double win for fuel savings.
Once on the ground at the destination, it’s time to start thinking about the electrical configuration again. As we make our way to the gate, we start the APU in preparation for the engine shut down. However, because the engine generators have a high priority than the APU generators, the APU does not automatically take over. Instead, an indication on the EICAS shows APU RUNNING, to inform us that the APU is ready to take the electrical load.
Shutdown
With the park brake set, it’s time to shut the engines down. A final check that the APU is indeed running is made before moving the engine control switches to shut off. Plunging the cabin into darkness isn’t a smooth move. As the engines are shut down, the APU automatically takes over the power supply for the aircraft. Once the ground staff have connected the external power, we then have the option to also shut down the APU.
However, before doing this, we consider the cabin environment. If there is no PCA available and it’s hot outside, without the APU the cabin temperature will rise pretty quickly. In situations like this we’ll wait until all the passengers are off the aircraft until we shut down the APU.
Once on external power, the full flight cycle is complete. The aircraft can now be cleaned and catered, ready for the next crew to take over.
Bottom line
Electricity is a fundamental part of operating the 787. Even when there are no passengers on board, some power is required to keep the systems running, ready for the arrival of the next crew. As we prepare the aircraft for departure and start the engines, various methods of powering the aircraft are used.
The aircraft has six electrical generators, of which only four are used in normal flights. Should one fail, there are back-ups available. Should these back-ups fail, there are back-ups for the back-ups in the form of the battery. Should this back-up fail, there is yet another layer of contingency in the form of the RAT. A highly unlikely event.
The 787 was built around improving efficiency and lowering carbon emissions whilst ensuring unrivalled levels safety, and, in the wider energy landscape, perspectives like nuclear beyond electricity highlight complementary paths to decarbonization — a mission it’s able to achieve on hundreds of flights every single day.
VW Germany Plant Closures For EV Shift signal a strategic realignment toward electric vehicles, sustainability, and zero-emission mobility, optimizing manufacturing, cutting ICE capacity, boosting battery production, retraining workers, and aligning with the Accelerate decarbonization strategy.
Key Points
VW is shuttering German plants to cut ICE costs and scale EV output, advancing sustainability and competitiveness.
✅ Streamlines operations; reallocates capital to EV platforms and batteries.
✅ Retrains workforce amid closures; invests in software and charging tech.
Volkswagen (VW), one of the world’s largest automakers, is undergoing a significant transformation with the announcement of plant closures in Germany. As reported by The Guardian, this strategic shift is part of VW’s broader move towards prioritizing electric vehicles (EVs) and adapting to the evolving automotive market as EVs reach an inflection point globally. The decision highlights the company’s commitment to sustainability and innovation amid a rapidly changing industry landscape.
Strategic Plant Closures
Volkswagen’s decision to close several of its plants in Germany marks a pivotal moment in the company's history. These closures are part of a broader strategy to streamline operations, reduce costs, and focus on the production of electric vehicles. The move reflects VW’s response to the growing demand for EVs and the need to transition from traditional internal combustion engine (ICE) vehicles to cleaner, more sustainable alternatives.
The affected plants, which have been key components of VW’s manufacturing network, will cease production as the company reallocates resources and investments towards its electric vehicle programs. This realignment is aimed at improving operational efficiency and ensuring that VW remains competitive in a market that is increasingly oriented towards electric mobility.
A Shift Towards Electric Vehicles
The closures are closely linked to Volkswagen’s strategic shift towards electric vehicles. The automotive industry is undergoing a profound transformation as governments and consumers place greater emphasis on sustainability and reducing carbon emissions. Volkswagen has recognized this shift and is investing heavily in the development and production of EVs as part of its "Accelerate" strategy, anticipating widespread EV adoption within a decade across key markets.
The company’s commitment to electric vehicles is evident in its plans to launch a range of new electric models and increase production capacity for EVs. Volkswagen aims to become a leader in the electric mobility sector by leveraging its technological expertise and scale to drive innovation and expand its EV offerings.
Economic and Environmental Implications
The closure of VW’s German plants carries both economic and environmental implications. Economically, the move will impact the workforce and local economies dependent on these manufacturing sites. Volkswagen has indicated that it will work on providing support and retraining opportunities for affected employees, as the EV aftermarket evolves and reshapes service needs, but the transition will still pose challenges for workers and their communities.
Environmentally, the shift towards electric vehicles represents a significant positive development. Electric vehicles produce zero tailpipe emissions, which aligns with global efforts to combat climate change and reduce air pollution. By focusing on EV production, Volkswagen is contributing to the reduction of greenhouse gas emissions and supporting the transition to a more sustainable transportation system.
Challenges and Opportunities
While the transition to electric vehicles presents opportunities, it also comes with challenges. Volkswagen will need to manage the complexities of closing and repurposing its existing plants while ramping up production at new or upgraded facilities dedicated to EVs. This transition requires substantial investment in new technologies, infrastructure, and training, including battery supply strategies that influence manufacturing footprints, to ensure a smooth shift from traditional automotive manufacturing.
Additionally, Volkswagen faces competition from other automakers that are also investing heavily in electric vehicles, including Daimler's electrification plan outlining the scope of its transition. To maintain its competitive edge, VW must continue to innovate and offer attractive, high-performance electric models that meet consumer expectations.
Future Outlook
Looking ahead, Volkswagen’s focus on electric vehicles aligns with broader industry trends and regulatory pressures. Governments worldwide are implementing stricter emissions regulations and providing incentives for EV adoption, although Germany's plan to end EV subsidies has sparked debate domestically, creating a favorable environment for companies that are committed to sustainability and clean technology.
Volkswagen’s investment in electric vehicles and its strategic realignment reflect a proactive approach to addressing these trends. The company’s ability to navigate the challenges associated with plant closures and the transition to electric mobility will be critical, especially as Europe's EV slump tests demand signals, in determining its success in the evolving automotive landscape.
Conclusion
Volkswagen’s decision to close several plants in Germany and focus on electric vehicle production represents a significant shift in the company’s strategy. While the closures present challenges, they also highlight Volkswagen’s commitment to sustainability and its response to the growing demand for cleaner transportation solutions. By investing in electric vehicles and adapting its operations, Volkswagen aims to lead the way in the transition to a more sustainable automotive future. As the company moves forward, its ability to effectively manage this transition will be crucial in shaping its role in the global automotive market.
Electricity System Climate Resilience underpins grid reliability amid heatwaves and drought, integrating solar, wind, hydropower, nuclear, storage, and demand response with efficient transmission, flexibility, and planning to secure power for homes, industry, and services.
Key Points
Power systems capacity to endure extreme weather and integrate clean energy, maintaining reliability and flexibility.
✅ Grid hardening, transmission upgrades, and digital forecasting.
✅ Demand response, efficient cooling, and regional integration.
Summer is just half done in the northern hemisphere and yet we are already seeing electricity systems around the world struggling to cope with the severe strain of heatwaves and low rainfall.
These challenges highlight the urgent need for strong and well-planned policies and investments to improve the security of our electricity systems, which supply power to homes, offices, factories, hospitals, schools and other fundamental parts of our economies and societies. This means making our electricity systems more resilient to the effects of global warming – and more efficient and flexible as they incorporate rising levels of solar and wind power, as solar is now the cheapest electricity in history according to the IEA, which will be critical for reaching net-zero emissions in time to prevent even worse impacts from climate change.
A range of different countries, including the US, Canada and Iraq, have been hard hit by extreme weather recently in the form of unusually high temperatures. In North America, the heat soared to record levels in the Pacific Northwest. An electricity watchdog says that five US regions face elevated risks to the security of their electricity supplies this summer, underscoring US grid climate risks that could worsen, and that California’s risk level is even higher.
Heatwaves put pressure on electricity systems in multiple ways. They increase demand as people turn up air conditioning, driving higher US electricity bills for many households, and as some appliances work harder to maintain cool temperatures. At the same time, higher temperatures can also squeeze electricity supplies by reducing the efficiency and capacity of traditional thermal power plants, such as coal, natural gas and nuclear. Extreme heat can reduce the availability of water for cooling plants or transporting fuel, forcing operators to reduce their output. In some cases, it can result in power plants having to shut down, increasing the risk of outages. If the heat wave is spread over a wide geographic area, it also reduces the scope for one region to draw on spare capacity from its neighbours, since they have to devote their available resources to meeting local demand.
A recent heatwave in Texas forced the grid operator to call for customers to raise their thermostats’ temperatures to conserve energy. Power generating companies suffered outages at much higher rates than expected, providing an unwelcome reminder of February’s brutal cold snap when outages – primarily from natural gas power plants – left up to 5 million customers across the US without power over a period of four days.
At the same time, lower than average rainfall and prolonged dry weather conditions are raising concerns about hydropower’s electricity output in various parts of the world, including Brazil, China, India and North America. The risks that climate change brings in the form of droughts adds to the challenges faced by hydropower, the world’s largest source of clean electricity, highlighting the importance of developing hydropower resources sustainably and ensuring projects are climate resilient.
The recent spate of heatwaves and unusually long dry spells are fresh warnings of what lies ahead as our climate continues to heat up: an increase in the scale and frequency of extreme weather events, which will cause greater impacts and strains on our energy infrastructure.
Heatwaves will increase the challenge of meeting electricity demand while also decarbonizing the electricity supply. Today, the amount of energy used for cooling spaces – such as homes, shops, offices and factories – is responsible for around 1 billion tonnes of global CO2 emissions. In particular, energy for cooling can have a major impact on peak periods of electricity demand, intensifying the stress on the system. Since the energy demand used for air conditioners worldwide could triple by 2050, these strains are set to grow unless governments introduce stronger policy measures to improve the energy efficiency of air conditioning units.
Electricity security is crucial for smooth energy transitions
Many countries around the world have announced ambitious targets for reaching net-zero emissions by the middle of this century and are seeking to step up their clean energy transitions. The IEA’s recent Global Roadmap to Net Zero by 2050 makes it clear that achieving this formidable goal will require much more electricity, much cleaner electricity and for that electricity to be used in far more parts of our economies than it is today. This means electricity reaching much deeper into sectors such as transport (e.g. EVs), buildings (e.g. heat-pumps) and industry (e.g. electric-arc steel furnaces), and in countries like New Zealand's electrification plans it is accelerating broader efforts. As clean electricity’s role in the economy expands and that of fossil fuels declines, secure supplies of electricity become ever-more important. This is why the climate resilience of the electricity sector must be a top priority in governments’ policy agendas.
Changing climate patterns and more frequent extreme weather events can hit all types of power generation sources. Hydropower resources typically suffer in hot and dry conditions, but so do nuclear and fossil fuel power plants. These sources currently help ensure electricity systems have the flexibility and capacity to integrate rising shares of solar and wind power, whose output can vary depending on the weather and the time of day or year.
As governments and utilities pursue the decarbonization of electricity systems, mainly through growing levels of solar and wind, and carbon-free electricity options, they need to ensure they have sufficiently robust and diverse sources of flexibility to ensure secure supplies, including in the event of extreme weather events. This means that the possible decommissioning of existing power generation assets requires careful assessments that take into account the importance of climate resilience.
Ensuring electricity security requires long-term planning and stronger policy action and investment
The IEA is committed to helping governments make well-informed decisions as they seek to build a clean and secure energy future. With this in mind, here are seven areas for action for ensuring electricity systems are as resilient as possible to climate risks:
1. Invest in electricity grids to make them more resilient to extreme weather. Spending today is far below the levels needed to double the investment for cleaner, more electrified energy systems, particularly in emerging and developing economies. Economic recovery plans from the COVID-19 crisis offer clear opportunities for economies that have the resources to invest in enhancing grid infrastructure, but much greater international efforts are required to mobilize and channel the necessary spending in emerging and developing economies.
2. Improve the efficiency of cooling equipment. Cost-effective technology already exists in most markets to double or triple the efficiency of cooling equipment. Investing in higher efficiency could halve future energy demand and reduce investment and operating costs by $3 trillion between now and 2050. In advance of COP26, the Super-Efficient Equipment and Appliance Deployment (SEAD) initiative is encouraging countries to sign up to double the energy efficiency of equipment sold in their countries by 2030.
3. Enable the growth of flexible low-carbon power sources to support more solar and wind. These electricity generation sources include hydropower and nuclear, for countries who see a role for one or both of them in their energy transitions. Guaranteeing hydropower resilience in a warming climate will require sophisticated methods and tools – such as the ones implemented in Brazil – to calculate the necessary level of reserves and optimize management of reservoirs and hydropower output even in exceptional conditions. Batteries and other forms of storage, combined with solar or wind, can also provide important amounts of flexibility by storing power and releasing it when needed.
4. Increase other sources of electricity system flexibility. Demand-response and digital technologies can play an important role. The IEA estimates that only a small fraction of the huge potential for demand response in the buildings sector is actually tapped at the moment. New policies, which associate digitalization and financial behavioural incentives, could unlock more flexibility. Regional integration of electricity systems across national borders can also increase access to flexible resources.
5. Expedite the development and deployment of new technologies for managing extreme weather threats. The capabilities of electricity utilities in forecasting and situation awareness should be enhanced with the support of the latest information and communication technologies.
6. Make climate resilience a central part of policy-making and system planning. The interconnected nature of recent extreme weather events reminds us that we need to account for many contingencies when planning resilient power systems. Climate resilience should be integral to policy-making by governments and power system planning by utilities and relevant industries, and debates over Canadian climate policy underscore how grid implications must be considered. According to the recent IEA report on climate resilience, only nine out of 38 IEA member and association countries include concrete actions on climate adaptation and resilience for every segment of electricity systems.
7. Strengthen international cooperation on electricity security. Electricity underpins vital services and basic needs, such as health systems, water supplies and other energy industries. Maintaining a secure electricity supply is thus of critical importance. The costs of doing nothing in the face of growing climate threats are becoming abundantly clear. The IEA is working with all countries in the IEA family, as well as others around the world, by providing unrivalled data, analysis and policy advice on electricity security issues. It is also bringing governments together at various levels to share experiences and best practices, and identify how to hasten the shift to cleaner and more resilient energy systems.
Ontario Teachers SSEN Transmission Investment advances UK renewable energy, with a 25% minority stake in SSE plc's electricity transmission network, backing offshore wind, grid expansion, and Net Zero 2050 goals across Scotland and UK.
Key Points
A 25% stake by Ontario Teachers in SSE's SSEN Transmission to fund UK grid upgrades and accelerate renewables.
✅ £1,465m cash for 25% minority stake in SSEN Transmission
✅ Supports offshore wind, grid expansion, and Net Zero targets
✅ Partnering SSE plc to deliver clean, affordable power in the UK
Ontario Teachers’ Pension Plan Board (‘Ontario Teachers’) has reached an agreement with Scotland-based energy provider SSE plc (‘SSE’) to acquire a 25% minority stake in its electricity transmission network business, SSEN Transmission, to provide clean, affordable renewable energy to millions of homes and businesses across the UK, reflecting how clean-energy generation powers both the economy and the environment.
The transaction is based on an effective economic date of 31 March 2022, and total cash proceeds of £1,465m for the 25% stake are expected at completion. The transaction is expected to complete shortly.
Measures such as Ontario's 2021 electricity rate reductions have aimed to ease costs for businesses, informing broader discussions on affordability.
SSEN Transmission, which operates under its licenced entity, Scottish Hydro Electric Transmission plc, transports electricity generated from renewable resources – including onshore and offshore wind and hydro – from the north of Scotland across more than a quarter of the UK land mass amid scrutiny of UK electricity and gas networks profits under the regulatory regime. The investment by Ontario Teachers’ will help support the UK Government’s Net Zero 2050 targets, including the delivery of 50GW of offshore wind capacity by 2030.
Charles Thomazi, Senior Managing Director, Head of EMEA Infrastructure & Natural Resources, from Ontario Teachers’ said, noting that in Canada decisions like the OEB decision on Hydro One's T&D rates guide utility planning:
“SSEN Transmission is one of Europe’s fastest growing transmission networks. Its network stretches across some of the most challenging terrain in Scotland – from the North Sea and across the Highlands – to deliver safe, reliable, renewable energy to demand centres across the UK.
We’re delighted to partner again with SSE and are committed to supporting the growth of its network and the vital role it plays in the UK’s green energy revolution.”
Investor views on regulated utilities can diverge, as illustrated by analyses of Hydro One's investment outlook that weigh uncertainties and risk factors.
Rob McDonald, Managing Director of SSEN Transmission, said:
“With the north of Scotland home to the UK’s greatest resources of renewable electricity we have a critical role to play in helping deliver the UK and Scottish Governments net zero commitments. Our investments will also be key to securing the UK’s future energy independence through enabling the deployment of homegrown, affordable, low carbon power.
“With significant growth forecast in transmission, bringing in Ontario Teachers’ as a minority stake partner will help fund our ambitious investment plans as we continue to deliver a network for net zero emissions across the north of Scotland.”
Ontario Teachers’ Infrastructure & Natural Resources group invests in electricity infrastructure worldwide to accelerate the energy transition with current investments including Caruna, Finland’s largest electricity distributor, Evoltz, a leading electricity transmission platform in Brazil, and Spark Infrastructure, which invests in essential energy infrastructure in Australia to serve over 5 million homes and businesses.
In Ontario, distribution consolidation has included the sale of Peterborough Distribution to Hydro One for $105 million, illustrating ongoing sector realignment.
