The career awareness program TradeUp for Success, promoting trades in the electricity sector to youth in Ontario, will now go national as the Electricity Sector Council takes over the Ontario program initiated by the Power Workers' Union, Hydro One, Bruce Power and Ontario Power Generation.
Building on the TradeUp for Success model created by the Power Workers' Union, these industry partners collaborated on the development, production and distribution of an educational package to help convey the very important message that careers in the trades in the electricity and renewable energy sector are rewarding, highly technical, cool choices for the youth of the future.
"The Power Workers' Union is proud to grant the Electricity Sector Council the license to expand TradeUp for Success to a national scope," said Don MacKinnon, President, Power Workers' Union. "To date we have shared our message with more than 500,000 parents, teachers, guidance councilors, government officials and students all over Ontario. We wish the Electricity Sector Council every success in expanding TradeUp for Success, and the PWU will continue to support the program in the future."
"The Electricity Sector Council is honoured to take over TradeUp for Success and build on the strong foundation of success achieved by its founders," said Tom Goldie, Chair, Board of Directors, Electricity Sector Council and Senior Vice-President, Corporate, Hydro One. "Canada is facing a potential crisis, a shortage in skilled labour - TradeUp for Success will raise awareness in youth across the country of the many different, challenging and rewarding career options the electricity sector has to offer."
"TradeUp has been a success because it involves industry volunteers, who are tradespeople currently working in the electricity sector," said Debra Carey, Communications Officer, Power Workers' Union. "They share their work experiences in a face to face forum speaking directly to students and teachers by attending career days and job fairs in high schools across Ontario."
TradeUp for Success rolled out on April 19th, 2002. The TradeUp education package (launched in 2006) is a comprehensive resource for students, teachers and parents. The materials in the package were designed for use in the schools, and in particular to complement the Grade 10 Career studies curriculum.
"As the Electricity Sector Council takes ownership of TradeUp, we will be looking to industry and provincial partnerships to help implement the program nationally," said Catherine Cottingham, Executive Director & CEO, Electricity Sector Council. "We are grateful for the industry's tremendous demonstration of support by granting the Electricity Sector Council responsibility for the continuation of TradeUp, and we look forward to future opportunities to collaborate."
The Electricity Sector Council (ESC) is the hub for research into human resources trends and sector-specific solutions to Canada's skilled-labour shortage. The ESC was founded in 2005 as a not-for-profit partnership between business, labour, education and government. Its mandate is to address the need-demonstrated in an exhaustive report commissioned in 2004 by the Canadian Electricity Association and Human Resources and Skills Development Canada (HRSDC)-for sector-wide recruitment and retention strategies.
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.
France Negative Electricity Prices highlight surplus renewables as solar and wind output exceeds demand, driving grid flexibility, demand response, and storage signals while reshaping energy markets, lowering emissions, and improving economic efficiency and energy security.
Key Points
They occur when surplus solar and wind push wholesale power prices below zero, signaling flexible, low-carbon grids.
✅ Surplus solar and wind outpace demand, flipping price signals
✅ Incentivizes demand response, storage, and flexible loads

In a remarkable feat for renewable energy, France has recently experienced negative electricity prices due to an abundant supply of solar and wind power. This development highlights the country's progress towards sustainable energy solutions and underscores the potential of renewables to reshape global energy markets.
The Surge in Renewable Energy Supply
France's electricity grid benefited from a surplus of renewable energy generated by solar panels and wind turbines. During periods of peak production, such as sunny and windy days, the supply of electricity exceeded demand, leading to negative prices and reflecting how solar is reshaping price dynamics in Northern Europe.
Implications for Energy Markets
The occurrence of negative electricity prices reflects a shift towards a more flexible and responsive energy system. It demonstrates the capability of renewables to meet substantial portions of electricity demand reliably and economically, with evidence of falling wholesale prices in many markets, challenging traditional notions of energy supply and pricing dynamics.
Technological Advancements and Policy Support
Technological advancements in renewable energy infrastructure, coupled with supportive government policies and incentives, have played pivotal roles in France's achievement. Investments in solar farms, wind farms, and grid modernization, including the launch of France's largest battery storage platform by TagEnergy, have enhanced the efficiency and reliability of renewable energy integration into the national grid.
Economic and Environmental Benefits
The adoption of renewable energy sources not only reduces greenhouse gas emissions but also fosters economic growth and energy independence. By harnessing abundant solar and wind resources, France strengthens its energy security and reduces reliance on fossil fuels, contributing to long-term sustainability goals and reflecting a continental shift as renewable power has surpassed fossil fuels for the first time.
Challenges and Future Outlook
While France celebrates the success of negative electricity prices, challenges remain in scaling renewable energy deployment and optimizing grid management. Balancing supply and demand, integrating intermittent renewables, and investing in energy storage technologies are critical for ensuring grid stability and maximizing the benefits of renewable energy, particularly in addressing clean energy's curtailment challenge across modern grids.
Global Implications
France's experience with negative electricity prices serves as a model for other countries striving to transition to clean energy economies. It underscores the potential of renewables to drive economic prosperity, mitigate climate change impacts, and reshape global energy markets towards sustainability, as seen in Germany where solar-plus-storage is now cheaper than conventional power in several contexts.
Conclusion
France's achievement of negative electricity prices driven by renewable energy surplus marks a significant milestone in the global energy transition. By leveraging solar and wind power effectively, France demonstrates the feasibility and economic viability of renewable energy integration at scale. As countries worldwide seek to reduce carbon emissions and enhance energy resilience, France's example provides valuable insights and inspiration for advancing renewable energy agendas and accelerating towards a sustainable energy future.
Advanced Nuclear Reactors drive U.S. clean energy with small modular reactors, a new test facility at Idaho National Laboratory, and public-private partnerships accelerating nuclear innovation, safety, and cost reductions through DOE-backed programs and university simulators.
Key Points
Advanced nuclear reactors are next-gen designs, including SMRs, offering safer, cheaper, low-carbon power.
✅ DOE test facility at Idaho National Laboratory
✅ Small modular reactors with passive safety systems
✅ University simulators train next-gen nuclear operators
Energy Secretary Rick Perry is advancing plans to shift the United States towards next-gen nuclear power reactors.
The Energy Department announced this week it has launched a new test facility at the Idaho National Laboratory where private companies can work on advanced nuclear technologies, as the first new U.S. reactor in nearly seven years starts up, to avoid the high costs and waste and safety concerns facing traditional nuclear power plants.
“[The National Reactor Innovation Center] will enable the demonstration and deployment of advanced reactors that will define the future of nuclear energy,” Perry said.
With climate change concerns growing and net-zero emissions targets emerging, some Republicans and Democrats are arguing for the need for more nuclear reactors to feed the nation’s electricity demand. But despite nuclear plants’ absence of carbon emissions, the high cost of construction, questions around what to do with the spent nuclear rods and the possibility of meltdown have stymied efforts.
A new generation of firms, including Microsoft founder Bill Gates’ Terra Power venture, are working on developing smaller, less expensive reactors that do not carry a risk of meltdown.
“The U.S. is on the verge of commercializing groundbreaking nuclear innovation, and we must keep advancing the public-private partnerships needed to traverse the dreaded valley of death that all too often stifles progress,” said Rich Powell, executive director of ClearPath, a non-profit advocating for clean energy and green industrial strategies worldwide.
The new Idaho facility is budgeted at $5 million under next year’s federal budget, even as the cost of U.S. nuclear generation has fallen to a ten-year low, which remains under negotiation in Congress.
On Thursday another advanced nuclear developer working on small modular systems, Oregon-based NuScale Power, announced it was building three virtual nuclear control rooms at Texas A&M University, Oregon State University and the University of Idaho, with funding from the Energy Department.
The simulators will be open to researchers and students, to train on the operation of smaller, modular reactors, as well as the general public.
NuScale CEO John Hopkins said the simulators would “help ensure that we educate future generations about the important role nuclear power and small modular reactor technology will play in attaining a safe, clean and secure energy future for our country.”
Maritime Electric Hurricane Irma Response details utility crews aiding Turks and Caicos with power restoration, storm recovery, debris removal, and essential services, coordinated with Fortis Inc., despite limited equipment, heat, and over 1,000 downed poles.
Key Points
A utility mission restoring power and essential services in Turks and Caicos after Irma, led by Maritime Electric.
✅ Over 1,000 poles down; crews climbing without bucket trucks
✅ Restoring hospitals, water, and communications first
✅ Fortis Inc. coordination; 2-3 week deployment with follow-on crews
Maritime Electric has sent a crew to help in the clean up and power restoration of Turks and Caicos after the Caribbean island was hit by Hurricane Irma, a storm that also saw FPL's massive response across Florida.
They arrived earlier this week and are working on removing debris and equipment so when supplies arrive, power can be brought back online, and similar mutual aid deployments, including Canadian crews to Florida, have been underway as well.
Fortis Inc., the parent company for Maritime Electric operates a utility in Turks and Caicos.
Kim Griffin, spokesperson for Maritime Electric, said there are over 1000 poles that were brought down by the storm, mirroring Florida restoration timelines reported elsewhere.
"It's really an intense storm recovery," she said. 'Good spirits'
The crew is working with less heavy equipment than they are used to, climbing poles instead of using bucket trucks, in hot and humid weather.
Griffin said their focus is getting essential services restored as quckly as possible, similar to progress in Puerto Rico's restoration efforts following recent hurricanes.
The crew will be there for two or three weeks and Griffin said Maritime Electric may send another group, as seen with Ontario's deployment to Florida, to continue the job.
She said the team has been well received and is in "good spirits."
"The people around them have been very positive that they're there," she said.
"They've said it's just been overwhelming how kind and generous the people have been to them."

Puerto Rico Earthquakes continue as a seismic swarm with aftershocks, landslides near Pe f1uelas, damage in Ponce and Guayanilla, grid outages from Costa Sur Plant, PREPA recovery, vulnerable buildings post-Hurricane Maria raising safety concerns.
Key Points
Recurring seismic events impacting Puerto Rico, causing damage, aftershocks, outages, and displacement.
✅ Seismic swarm with 6.4 and 5.9 magnitude quakes and ongoing aftershocks
✅ Costa Sur Plant offline; PREPA urges conservation amid grid repairs
✅ Older, code-deficient buildings and landslides raise safety risks
Some in Puerto Rico are beginning to fear the ground will never stop shaking. The island has been pummeled by hundreds of earthquakes in recent weeks, including the recent 5.9 magnitude temblor, where there were reports of landslides in the town of Peñuelas along the southern coast, rattling residents already on edge from the massive 6.4 magnitude quake, and raising wider concerns about climate risks to the grid in disaster-prone regions.
That was the largest to strike the island in more than a century causing hundreds of structures to crumble, forcing thousands from their homes and leaving millions without power, a scenario echoed by Texas power outages during winter storms too. One person was killed and several others injured.
Utility says 99% of customers have electricity
Puerto Rico's public utility, PREPA, tweeted some welcome news Monday: that nearly all of the homes and businesses it serves have had electric power restored. Still it is urging customers to conserve energy amid utility supply-chain shortages that can slow critical repairs.
Reporting from the port city of Ponce, NPR's Adrian Florido said the Costa Sur Plant, which produces more than 40% of Puerto Rico's electricity, was badly damaged in last week's quake. It remains offline indefinitely, even as grid operators elsewhere have faced California blackout warnings during extreme heat.
He also reports many residents are still reeling from the devastation caused by Hurricane Maria, a deadly Category 4 storm that battered the island in September 2017. The storm exposed the fact that buildings across the island were not up to code, similar to how aging systems have contributed to PG&E power line fires in California. The series of earthquakes are only amplifying fears that structures have been further weakened.
"People aren't coping terribly well," Florido said on NPR's Morning Edition Monday, noting that households elsewhere have endured pandemic power shutoffs and burdensome bills.
Many earthquake victims sleeping outdoors
Florido spoke to one displaced resident, Leticia Espada, who said more than 50 homes in her town of Guayanilla, about an hour drive east of the port city of Ponce, had collapsed.
After sleeping outside for days on her patio following Tuesday's quake, she eventually came to her town's baseball stadium where she's been sleeping on one of hundreds of government-issued cots.
She's like so many others sleeping in open-air shelters, many unwilling to go back to their homes until they've been deemed safe, while even far from disaster zones, brief events like a Northeast D.C. outage show how fragile service can be.
"Thousands of people across several towns sleeping in tents or under tarps, or out in the open, protected by nothing but the shade of a tree with no sense of when these quakes are going to stop," Florido reports.
