A $6.2-billion deal has been reached to develop power from the proposed Lower Churchill hydroelectric project in Labrador, Emera Inc. announced.
Emera says under the agreement, Newfoundland and LabradorÂ’s Crown utility, Nalcor Energy, would spend $2.9 billion to build a power generating facility at Muskrat Falls.
A transmission link from Labrador to Newfoundland would cost $2.1 billion, $600 million of which would be provided by Emera.
A link between Newfoundland to Nova Scotia would cost $1.2 billion, all funded by Emera, which owns Nova Scotia Power.
In a statement issued by Emera, Premiers Danny Williams and Darrell Dexter touted the agreement as one that would provide cleaner, affordable electricity and boost Atlantic CanadaÂ’s economy.
“This is an extremely exciting and proud day for our province as we move forward with plans to develop the Lower Churchill project — the most attractive clean, renewable energy project in North America,” Williams said in a statement.
“This is an historic day for Nova Scotia and all of Atlantic Canada,” added Dexter. “It lifts the idea of Atlantic co-operation off the page and turns it into fundamental action, building a more prosperous nation.”
The agreement is subject to approval by regulators in Nova Scotia and Newfoundland and Labrador. Under the agreement, Nova Scotia would receive 20 per cent of the power generated at Muskrat Falls for 35 years.
Emera has been in negotiations to develop Lower Churchill power since a memorandum of understanding was signed in January 2008.
Nalcor officials have said it would take about five years to get energy flowing to Nova Scotia once a deal is signed.
Last month, Williams announced he was pursuing the Lower Churchill project in two phases. He said his plan was to build a generating station at Muskrat Falls, followed by a larger facility upriver at Gull Island.
The multibillion-dollar project has been on the drawing board in one form or another for decades. In 1980, it passed an environmental assessment but was set aside due to concerns over market access and financing.
Concerns over the loss of habitat that would result from the development of the project have also stalled its progress. But Nalcor has promised to develop a compensation plan to make up for that.
The desire to build more power plants on the Churchill River in central Labrador can be traced back to 1972, when the Churchill Falls hydroelectric dam was finished with QuebecÂ’s help.
Under that deal, which doesnÂ’t expire until 2041 and is often criticized by Williams, Quebec has reaped more than $19 billion in profits while Newfoundland has pocketed only $1 billion, according to the Newfoundland and Labrador government.
As a result of that deal, Newfoundland and Labrador has sought an alternate route for Lower Churchill power that bypasses Quebec.
Switch-On Project Electric Trucks accelerate California freight decarbonization, deploying Volvo VNR Electric rigs with high-capacity charging infrastructure, zero-emissions operations, and connected safety features to cut greenhouse gases and improve urban air quality.
Key Points
A California program deploying Volvo VNR Electric trucks and charging to decarbonize freight and improve air quality.
✅ 70 Volvo VNR Electric trucks for regional logistics
✅ Strategic high-capacity charging for heavy-duty fleets
✅ Lower TCO via fuel savings and reduced maintenance
In a significant step toward sustainable transportation, the Switch-On project is bringing 70 Volvo VNR Electric trucks to California. This initiative aims to bolster the state's efforts to reduce emissions and transition to greener logistics solutions. The arrival of these electric vehicles marks an important milestone in California's commitment to combating climate change and improving air quality.
The Switch-On Project: Overview and Goals
The Switch-On project is a collaborative effort designed to enhance electric truck adoption in California. It focuses on developing the necessary infrastructure and technology to support electric vehicles (EVs) in the freight and logistics sectors, building on recent nonprofit investments at California ports. The project not only seeks to increase the availability of electric trucks but also aims to demonstrate their effectiveness in real-world applications.
California has set ambitious goals for reducing greenhouse gas emissions, particularly from the transportation sector, which is one of the largest contributors to air pollution. By introducing electric trucks into freight operations, the state aims to significantly cut emissions, improve public health, and pave the way for a more sustainable future.
The Volvo VNR Electric Trucks
The Volvo VNR Electric trucks are specifically designed for regional distribution and urban transport, aligning with Volvo's broader electric lineup as the company expands offerings, making them ideal for the needs of California’s freight industry. With a range of approximately 250 miles on a single charge, these trucks can efficiently handle most regional routes. Equipped with advanced technology, including regenerative braking and connectivity features, the VNR Electric models enhance operational efficiency and safety.
These trucks not only provide a cleaner alternative to traditional diesel vehicles but also promise lower operational costs over time. With reduced fuel expenses and lower maintenance needs, and emerging vehicle-to-grid pilots that can create new value streams, businesses can benefit from significant savings while contributing to environmental sustainability.
Infrastructure Development
A crucial aspect of the Switch-On project is the development of charging infrastructure to support the new fleet of electric trucks. The project partners are working on installing high-capacity charging stations strategically located throughout California while addressing utility planning challenges that large fleets will pose to the power system. This infrastructure is essential to ensure that electric trucks can be charged efficiently, minimizing downtime and maximizing productivity.
The charging stations are designed to accommodate the specific needs of heavy-duty vehicles, and corridor models like BC's Electric Highway provide useful precedents for network design, allowing for rapid charging that aligns with operational schedules. This development not only supports the new fleet but also encourages other logistics companies to consider electric trucks as a viable option for their operations.
Benefits to California
The introduction of 70 Volvo VNR Electric trucks will have several positive impacts on California. Firstly, it will significantly reduce greenhouse gas emissions from the freight sector, contributing to the state’s ambitious climate goals even as grid expansion will be needed to support widespread electrification across sectors. The transition to electric trucks is expected to improve air quality, particularly in urban areas that struggle with high pollution levels.
Moreover, the project serves as a model for other regions considering similar initiatives. By showcasing the practicality and benefits of electric trucks, California hopes to inspire widespread adoption across the nation. As the market for electric vehicles continues to grow, this project can play a pivotal role in accelerating the transition to sustainable transportation solutions.
Industry and Community Reactions
The arrival of the Volvo VNR Electric trucks has been met with enthusiasm from both industry stakeholders and community members. Logistics companies are excited about the opportunity to reduce their carbon footprints and operational costs. Meanwhile, environmental advocates applaud the project as a crucial step toward cleaner air and healthier communities.
California’s commitment to sustainable transportation has positioned it as a leader in the shift to electric vehicles amid an ongoing biofuels vs. EVs debate over the best path forward, setting an example for other states and countries.
Conclusion
The Switch-On project represents a major advancement in California's efforts to transition to electric transportation. With the deployment of 70 Volvo VNR Electric trucks, the state is not only taking a significant step toward reducing emissions but also demonstrating the feasibility of electric logistics solutions.
As infrastructure develops and more electric trucks hit the roads, California is paving the way for a greener, more sustainable future in transportation. The success of this project could have far-reaching implications, influencing policies and practices in the broader freight industry and beyond.
Alberta-BC Pipeline Dispute centers on Trans Mountain expansion, diluted bitumen shipments, federal approval, spill response capacity, and electricity trade, as Alberta suspends power talks and Ottawa insists the Kinder Morgan project proceeds in national interest.
Key Points
Dispute over Trans Mountain expansion, bitumen limits, and jurisdiction between Alberta, B.C., and Canada.
✅ Alberta suspends BC electricity talks as leverage
✅ Ottawa affirms federal approval and spill response
✅ BC plans advisory panel on diluted bitumen risks
Alberta Premier Rachel Notley says her government is suspending talks with British Columbia on the purchase of electricity from the western province.
It’s the first step in Alberta’s fight against the B.C. government’s proposal to obstruct the Kinder Morgan oil pipeline expansion project by banning increased shipments of diluted bitumen to the province’s coast.
Up to $500 million annually for B.C.’s coffers from electricity exports hangs in the balance, Notley said.
“We’re prepared to do what it takes to get this pipeline built — whatever it takes,” she told a news conference Thursday after speaking with Prime Minister Justin Trudeau on the phone.
Notley said she told Trudeau, who’s in Edmonton for a town-hall meeting, that the federal government needs to act decisively to end the dispute.
Speaking on Edmonton talk radio station CHED earlier in the day, Trudeau said the pipeline expansion is in the national interest and will go ahead, even as the federal government undertakes a study on electrification across sectors.
“That pipeline is going to get built,” Trudeau said. “We will stand by our decision. We will ensure that the Kinder Morgan pipeline gets built.”
B.C.’s environment minister has said his minority government plans to ban increased shipments until it can determine that shippers are prepared and able to properly clean up a spill, and, separately, has implemented an electricity rate freeze affecting consumers. He said he will establish an independent scientific advisory panel to study the issue.
The move infuriated Notley, who has accused B.C. of trying to change the rules after the federal government gave the project the green light. B.C. has the right to regulate how any spills would be cleaned up, but can’t dictate what flows through pipelines, she said.
Trudeau said Canada needs to get Alberta’s oil safely to markets other than the U.S. energy market today. He said the federal government did the research and has spent billions on spill response.
“The Kinder Morgan pipeline is not a danger to the B.C. coast,” he said.
Notley said she thanked Trudeau for his assurance that the project will go ahead, but the federal government has to do more to ensure the pipeline’s expansion.
“This is not an Alberta-B.C. issue. This is a Canada-B.C. issue,” she said. “This kind of uncertainty is bad for investment and bad for working people
“Enough is enough. We need to get these things built.”
B.C. Premier John Horgan said his government consulted Alberta and Ottawa about his province’s intentions, noting that Columbia River Treaty talks also shape regional electricity policy.
“I don’t see what the problem is,” Horgan said Thursday at a school opening north of Kelowna, B.C. “It’s within our jurisdiction to put in place regulations to protect the public interest.
“That’s what we are doing.”
He downplayed any possibility of court action or sanctions by Alberta.
“There’s nothing to take to court,” Horgan said. “We are consulting with the people of B.C. It’s way too premature to talk about those sorts of issues.
“Sabre-rattling doesn’t get you very far.”
Speaking in Ottawa, Natural Resources Minister Jim Carr wouldn’t say what Canada might do if British Columbia implements its regulation.
“That’s speculative,” said Carr.
He noted at this point, B.C. has just pledged to consult. He said the federal government heard from thousands of people before the pipeline was approved.
“That’s what they have announced — an intention to consult. We have already consulted.”
B.C.’s proposal creates more uncertainty for Kinder Morgan’s already-delayed Trans Mountain expansion project that would nearly triple the capacity of its pipeline system to 890,000 barrels a day.
EU Nuclear Reactor Life Extension focuses on energy security, carbon-free electricity, and safety as ageing reactors face gas shortages, high power prices, and regulatory approvals across the UK and EU amid winter supply risks.
Key Points
EU Nuclear Reactor Life Extension is the policy to keep ageing reactors safely generating affordable, low-carbon power.
✅ Extends reactor operation via inspections and component upgrades
✅ Addresses gas shortages, price volatility, and winter supply risks
✅ Requires national regulator approval and cost-benefit analysis
Shaken by the loss of Russian natural gas since the invasion of Ukraine, European countries are questioning whether they can extend the lives of their ageing nuclear reactors to maintain the supply of affordable, carbon-free electricity needed for net-zero across the bloc — but national regulators, companies and governments disagree on how long the atomic plants can be safely kept running.
Europe avoided large-scale blackouts last winter despite losing its largest supplier of natural gas, and as Germany temporarily extended nuclear operations to bolster stability, but industry is still grappling with high electricity prices and concerns about supply.
Given warnings from the International Energy Agency that the coming winters will be particularly at risk from a global gas shortage, governments have turned their attention to another major energy source — even as some officials argue nuclear would do little to solve the gas issue in the near term — that would exacerbate the problem if it too is disrupted: Europe’s ageing fleet of nuclear power plants.
Nuclear accounts for nearly 10% of energy consumed in the European Union, with transport, industry, heating and cooling traditionally relying on coal, oil and natural gas.
Historically nuclear has provided about a quarter of EU electricity and 15% of British power, even as Germany shut down its last three nuclear plants recently, underscoring diverging national paths.
Taken together, the UK and EU have 109 nuclear reactors running, even as Europe is losing nuclear power in several markets, most of which were built in the 1970s and 1980s and were commissioned to last about 30 years.
That means 95 of those reactors — nearly 90% of the fleet — have passed or are nearing the end of their original lifespan, igniting debates over how long they can safely continue to be granted operating extensions, with some arguing it remains a needed nuclear option for climate goals despite age-related concerns.
Regulations differ across borders, with some countries such as Germany turning its back on nuclear despite an ongoing energy crisis, but life extension discussions are usually a once-a-decade affair involving physical inspections, cost/benefit estimates for replacing major worn-out parts, legislative amendments, and approval from the national nuclear safety authority.
Africa Energy Access Funding faces disbursement bottlenecks as SDG 7 goals demand investment in decentralized solar, minigrids, and rural electrification; COVID-19 pressures donors, requiring faster approvals, standardized documentation, and stronger project preparation and due diligence.
Key Points
Financing to expand Africa's electrification, advancing SDG 7 via disbursement to decentralized solar and minigrids.
✅ Accelerates investment for SDG 7 and rural electrification
✅ Prioritizes decentralized solar, minigrids, and utilities
✅ Speeds approvals, standard docs, and project preparation
The time frame from final funding approval to disbursement can be the most painful part of any financing process, and the access-to-electricity sector is not spared.
Amid the global spread of the coronavirus over the last few weeks, there have been several funding pledges to promote access to electricity in Africa. In March, the African Development Bank and other partners committed $160 million for the Facility for Energy Inclusion to boost electricity connectivity in Africa through small-scale solar systems and minigrids. Similarly, the Export-Import Bank of the United States allocated $91.5 million for rural electrification in Senegal.
Rockefeller chief wants to redefine 'energy poverty'
Rajiv Shah, president of The Rockefeller Foundation, believes that SDG 7 on energy access lacks ambition. He hopes to drive an effort to redefine it.
Currently, funding is not being adequately deployed to help achieve universal access to energy. The International Energy Agency’s “Africa Energy Outlook 2019” report estimated that an almost fourfold increase in current annual access-to-electricity investments — approximately $120 billion a year over the next 20 years — is required to provide universal access to electricity for the 530 million people in Africa that still lack it.
While decentralized renewable energy across communities, particularly solar, has been instrumental in serving the hardest-to-reach populations, tracking done by Sustainable Energy for All — in the 20 countries with about 80% of those living without access to sustainable energy — suggests that decentralized solar received only 1.2% of the total electricity funding.
The spread of COVID-19 is contributing significantly to Africa’s electricity challenges across the region, creating a surge in the demand for energy from the very important health facilities, an exponential increase in daytime demand as a result of most people staying and working indoors, and a rise from some food processing companies that have scaled up their business operations to help safeguard food security, among others. Thankfully — and rightly so — access-to-electricity providers are increasingly being recognized as “essential service” providers amid the lockdowns across cities.
To start tackling Africa’s electricity challenges more effectively, “funding-ready” energy providers must be able to access and fulfill the required conditions to draw down on the already pledged funding. What qualifies as “funding readiness” is open to argument, but having a clear, commercially viable business and revenue model that is suitable for the target market is imperative.
Developing the skills required to navigate the due-diligence process and put together relevant project documents is critical and sometimes challenging for companies without prior experience. Typically, the final form of all project-related agreements is a prerequisite for the final funding approval.
In addition, having the right internal structures in place — for example, controls to prevent revenue leakage, an experienced management team, a credible board of directors, and meeting relevant regulatory requirements such as obtaining permits and licenses — are also important indicators of funding readiness.
1. Support for project preparation. Programs — such as the Private Financing Advisory Network and GET.invest’s COVID-19 window — that provide business coaching to energy project developers are key to helping surmount these hurdles and to increasing the chances of these projects securing funding or investment. Donor funding and technical-assistance facilities should target such programs.
2. Project development funds. Equity for project development is crucial but difficult to attract. Special funds to meet this need are essential, such as the $760,000 for the development of small-scale renewable energy projects across sub-Saharan Africa recently approved by the African Development Bank-managed Sustainable Energy Fund for Africa.
3. Standardized investment documentation. Even when funding-ready energy project developers have secured investors, delays in fulfilling the typical preconditions to draw down funds have been a major concern. This is a good time for investors to strengthen their technical assistance by supporting the standardization of approval documents and funding agreements across the energy sector to fast-track the disbursement of funds.
4. Bundled investment approvals and more frequent approval sessions. While we implement mechanisms to hasten the drawdown of already pledged funding, there is no better time to accelerate decision-making for new access-to-electricity funding to ensure we are better prepared to weather the next storm. Donors and investors should review their processes to be more flexible and allow for more frequent meetings of investment committees and boards to approve transactions. Transaction reviews and approvals can also be conducted for bundled projects to reduce transaction costs.
5. Strengthened local capacity. African countries must also commit to strengthening the local manufacturing and technical capacity for access-to-electricity components through fiscal incentives such as extended tax holidays, value-added-tax exemptions, accelerated capital allowances, and increased investment allowances.
The ongoing pandemic and resulting impacts due to lack of electricity have further shown the need to increase the pace of implementation of access-to-electricity projects. We know that some of the required capital exists, and much more is needed to achieve Sustainable Development Goal 7 — about access to affordable and clean energy for all — by 2030.
It is time to accelerate our support for access-to-electricity companies and equip them to draw down on pledged funding, while calling on donors and investors to speed up their funding processes to ensure the electricity gets to those most in need.
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.
Germany's Economic Downturn reflects an energy crisis, deindustrialization risks, export weakness, and manufacturing stress, amid Russia gas loss, IMF and EU recession forecasts, and debates over electricity price caps and green transition.
Key Points
An economic contraction from energy price shocks, export weakness, and bottlenecks in manufacturing and digitization.
✅ Energy shock after loss of cheap Russian gas
✅ Exports slump amid China slowdown and weak demand
✅ Policy gridlock on power price cap and permits
Germany went from envy of the world to the worst-performing major developed economy. What happened?
For most of this century, Germany racked up one economic success after another, dominating global markets for high-end products like luxury cars and industrial machinery, selling so much to the rest of the world that half the economy ran on exports.
Jobs were plentiful, the government’s financial coffers grew as other European countries drowned in debt, and books were written about what other countries could learn from Germany.
No longer. Now, Germany is the world’s worst-performing major developed economy, with both the International Monetary Fund and European Union expecting it to shrink this year.
It follows Russia’s invasion of Ukraine and the loss of Moscow’s cheap Russian gas that underpinned industry — an unprecedented shock to Germany’s energy-intensive industries, long the manufacturing powerhouse of Europe.
The sudden underperformance by Europe’s largest economy has set off a wave of criticism, handwringing and debate about the way forward.
Germany risks “deindustrialization” as high energy costs and government inaction on other chronic problems threaten to send new factories and high-paying jobs elsewhere, said Christian Kullmann, CEO of major German chemical company Evonik Industries AG.
From his 21st-floor office in the west German town of Essen, Kullmann points out the symbols of earlier success across the historic Ruhr Valley industrial region: smokestacks from metal plants, giant heaps of waste from now-shuttered coal mines, a massive BP oil refinery and Evonik’s sprawling chemical production facility.
These days, the former mining region, where coal dust once blackened hanging laundry, is a symbol of the energy transition, as the power sector’s balancing act continues with wind turbines and green space.
The loss of cheap Russian natural gas needed to power factories “painfully damaged the business model of the German economy,” Kullmann told The Associated Press. “We’re in a situation where we’re being strongly affected — damaged — by external factors.”
After Russia cut off most of its gas to the European Union, spurring an energy crisis in the 27-nation bloc that had sourced 40% of the fuel from Moscow, the German government asked Evonik to turn to coal by keeping its 1960s coal-fired power plant running a few months longer.
The company is shifting away from the plant — whose 40-story smokestack fuels production of plastics and other goods — to two gas-fired generators that can later run on hydrogen amid plans to become carbon neutral by 2030 and following the nuclear phase-out of recent years.
One hotly debated solution: a government-funded cap on industrial electricity prices to get the economy through the renewable energy transition, amid an energy crisis that even saw a temporary nuclear extension to stabilize supply.
