At the recent NG Utilities Summit Australia discussions centered around the role the Smart Grid will play in transforming energy delivery in Australia.

One hundred movers and shakers from the Australian Utilities sector met recently at the Surfers Paradise Marriott Resort and Spa, Gold Coast in a closed door environment to discuss the major changes that are reshaping the traditional roles of utilities, creating opportunities for new technologies, and how it is redefining the scope and character of the sectors interface with customers and communities.

Amongst the standout discussions of the three days were the keynotes delivered by Terry Effeney – CEO, Energex , Queensland’s largest electricity provider and that of Peter Birk – CTO, EnergyAustralia.

“The utilities sector is experiencing an unprecedented paradigm shift that holds promise of opportunity, but knowledge of significant risk,” said Terry Effeney during his keynote address, adding that “during the next two decades the industry will see a gradual shift away from the traditional centrally focused ‘generation-transmission-distribution’ paradigm to a more customer driven distributed energy resource DER model.”

He also pointed to significant innovation playing a major role in the delivery of energy to customers in efforts to better align their economic requirements and the community's needs for improved environment stewardship.

“The strategies for the future that Energex spoke to were based around utilizing the existing infrastructure but needing to manage the assets, energy flows and work processes with 21st century technology which will provide, not only improved asset management and customer service, but provide a platform on which additional new technologies could be implemented.”

Peter Birk spoke candidly about the extensive smart grid program run by EnergyAustralia being at the forefront of innovation internationally.

“The program looks to the development and implementation of a range of grid and customer side solutions to make organizations more productive, improve their network reliability and to create innovative customer solutions.

“In light of EnergyAustralia’s recent award in receiving the federal government's $100 million Smart Grid, Smart City grant it was fascinating to learn the detail to how EnergyAustralia will leverage its existing program to deliver the Smart Grid, Smart City. Stating that a key success factor for the delivery of Smart Grid, Smart City will be engagement with other industry participants and the dissemination of information with the broader industry, to ensure results from the demonstration are largely appropriate Australia wide.”

These comments from Mr. Birk were well received by the utilities sector.

Tunisia moves ahead with smart electricity grid

Tunisia Smart Grid Project advances with an AFD loan as STEG deploys smart meters in Sfax, upgrades grid infrastructure, boosts energy efficiency, curbs losses, and integrates renewable energy through digitalization and advanced communication systems.

 

Key Points

A national program funded by an AFD $131.7M loan to modernize STEG, deploy smart meters, and integrate renewable energy.

✅ 430,000 smart meters in Sfax during phase one

✅ 20-year AFD loan with 7-year grace period

✅ Cuts losses, improves efficiency, enables renewables

 

The Tunisian parliament has approved taking a $131.7 million loan from the French Development Agency for the implementation of a smart grid project.

Parliament passed legislation regarding the 400 million dinar ($131.7 million) loan plus a grant of $1.1 million.

The loan, to be repaid over 20 years with a grace period of up to 7 years, is part of the Tunisian government’s efforts to establish a strategy of energy switching aimed at reducing costs and enhancing operational efficiency.

The move to the smart grid had been postponed after the Tunisian Company of Electricity and Gas (STEG) announced in March 2017 that implementation of the first phase of the project would begin in early 2018 and cover the entire country by 2023.

STEG was to have received funding some time ago. Last year at the Africa Smart Grid Summit in Tunis, the company said it would initiate an international tender during the first quarter of 2019 to start the project.

The French funding is to be allocated to implementation of the first phase only, which will involve development of control and communication stations and the improvement of infrastructure, where regulatory outcomes such as the Hydro One T&D rates decision can influence investment planning in comparable markets.

It includes installation of 430,000 “intelligent” metres over three years in Sfax governorate in southern Tunisia. The second phase of the project is planned to extend the programme to the rest of the country.

Smart metres to be installed in homes and businesses in Sfax account for about 10% of the total number of metres to be deployed in Tunisia.

At the beginning of 2017, the Industrial Company of Metallic Articles (SIAM), a Tunisian industrial electrical equipment and machinery company, signed an agreement with Huawei for the Chinese company to supply smart electricity metres. The value of the deal was not disclosed.

The smart grid is designed to reduce power waste, reduce the number of unpaid bills, prevent consumer fraud such as power theft in India across distribution networks, improve the ecosystem and increase competitiveness in the electricity sector.

Experts said the main difference between the traditional and smart grids is the adoption of advanced infrastructure for measuring electricity consumption and for communication between the power plant and consumers. The data exchange allows power plants to coordinate electricity production with actual demand.

STEG previously indicated that it had implemented measures to ensure the transition to the smart grid, especially since digitalisation is playing an important role in the energy sector.

The project, which translates Tunisia’s energy plans in the form of a partnership between the public and private sectors, aims at reaching 30% of the country’s electricity need from renewable sources by 2025, even as entities like the TVA face climate goals scrutiny that can affect electricity rates in other markets.

The development of the smart grid will allow STEG to monitor consumption patterns, detect abuses and remotely monitor the grid’s power supply, at a time when regulators have questioned UK network profits to spur efficiency, underscoring the value of transparency.

“The smart grid will change the face of the energy system towards the use of renewable energies,” said Tunisian Industry Minister Slim Feriani. At the forum on alternative energies, he pointed out that energy sector digitisation requires investments in technology and a change in the consumption mentality, as new entrants consider roles like Tesla electricity retailer plans in advanced markets.

Official data indicate that Tunisia’s energy deficit accounts for one-third of the country’s annual trade deficit, which reached record levels of more than $6 billion last year.

STEG, whose debts have reached $329 million over the past eight years, a situation resembling Manitoba Hydro debt pressures in Canada, has not disclosed when and how funding would be secured for the completion of the second phase. The company insists it is working to prevent further losses and to collect its unpaid bills.

STEG CEO Moncef Harrabi, earlier this year, said: “The current situation of the company has forced us to take immediate action to reduce the worsening of the crisis and stop the financial bleeding caused by losses.”

He said the company had repeatedly asked the government to pay subsidy instalments due to the company and to enact binding decisions to force government institutions and departments to pay electricity bills, while elsewhere measures like Thailand power bill cuts have been used to support consumers.

The Tunisian government has yet to disburse the subsidy instalments due STEG for 2018 and 2019, which amount to $658 million. STEG also imports natural gas from Algeria for its power plants at a cost of $1.1 billion a year.

Sunrun and Tesla Unveil Texas Power Plant

Sunrun-Tesla Virtual Power Plant Texas leverages residential solar, Tesla Powerwall battery storage, and ERCOT demand response to enhance grid resilience, cut emissions, and supply backup power via a coordinated distributed energy resources network.

 

Key Points

A Texas VPP using residential solar and Tesla Powerwall to aid ERCOT with grid services resilience, and less emissions.

✅ Aggregates Powerwall storage for ERCOT demand response.

✅ Enhances grid reliability with distributed energy resources.

✅ Cuts emissions by shifting solar to peak and outage periods.

 

In a significant development for renewable energy and grid resilience, Sunrun and Tesla have announced a groundbreaking partnership to establish a distributed power plant in Texas. This collaboration represents a major step forward in harnessing solar energy and battery storage, with advances in affordable solar batteries helping to create a more reliable and sustainable power system. The initiative aims to address the growing demand for clean energy solutions while enhancing grid stability and resilience in one of the largest and most energy-dependent states in the U.S.

The new distributed power plant, a joint venture between Sunrun, a leading residential solar provider, and Tesla, renowned for its advanced battery technology and electric vehicles, will leverage the strengths of both companies to transform how energy is generated and used. The project will deploy Tesla's Powerwall battery systems alongside Sunrun's solar panels to create a network of interconnected residential energy storage units. This network will function as a virtual power plant, aligned with emerging peer-to-peer energy sharing models that are capable of providing electricity back to the grid during periods of high demand or outages.

Texas, with its vast and growing population, has faced significant energy challenges in recent years. The state’s power grid, managed by the Electric Reliability Council of Texas (ERCOT), has experienced strain during extreme weather events and high demand periods, and instances of Texas wind curtailment during grid stress, leading to concerns about reliability and stability. The partnership between Sunrun and Tesla seeks to address these concerns by introducing a more flexible and resilient energy solution.

The distributed power plant will consist of thousands of residential solar installations, each equipped with Tesla Powerwall batteries, reflecting the broader trend of pairing storage with solar across the U.S. as it scales. These batteries store excess solar energy generated during the day and release it when needed, such as during peak demand times or power outages. By connecting these systems through advanced software, the project will create a coordinated network of distributed energy resources that can respond dynamically to fluctuations in energy supply and demand.

One of the key benefits of this distributed approach is its ability to enhance grid reliability. Traditional power plants are centralized and can be vulnerable to disruptions, whether from extreme weather, technical failures, or other issues. In contrast, a distributed power plant spreads the generation and storage capacity across numerous locations, a principle echoed by renewable power developers pursuing multi-resource projects today, reducing the risk of widespread outages and increasing the overall resilience of the power grid.

Additionally, the project will contribute to the reduction of greenhouse gas emissions. By increasing the use of solar energy and reducing reliance on fossil fuels, and amid ongoing work to improve solar and wind technologies, the distributed power plant supports Texas’s climate goals and contributes to broader efforts to combat climate change. The integration of renewable energy sources into the grid helps to decrease carbon emissions and promote a cleaner, more sustainable energy system.

The partnership between Sunrun and Tesla also underscores the growing role of technology in transforming the energy landscape. Tesla's Powerwall battery systems represent some of the most advanced energy storage technology available, and amid record solar and storage growth nationwide this decade they showcase the capability to store and manage energy efficiently. Sunrun’s expertise in residential solar installations complements this technology, creating a powerful combination that leverages the latest advancements in clean energy.

The project is expected to deliver several benefits to both individual homeowners and the broader community. Homeowners who participate in the program will have access to solar energy and battery storage at reduced costs, thanks to the economies of scale and innovative financing options provided by Sunrun and Tesla. Additionally, they will have the added security of backup power during outages, contributing to greater energy independence and resilience.

For the broader community, the distributed power plant offers a more reliable and sustainable energy system. The ability to generate and store energy at the residential level reduces the strain on traditional power plants and enhances the overall stability of the grid. Furthermore, the project will contribute to local job creation, as the installation and maintenance of solar panels and battery systems require skilled workers.

As the project moves forward, Sunrun and Tesla will work closely with local stakeholders, regulators, and utility providers to ensure the successful implementation and integration of the distributed power plant. Collaboration with these parties will be essential to addressing any regulatory, technical, or logistical challenges and ensuring that the project delivers its intended benefits.

In conclusion, the partnership between Sunrun and Tesla to create a distributed power plant in Texas represents a significant advancement in clean energy technology and grid resilience. By combining solar power with advanced battery storage, the project aims to enhance grid stability, reduce emissions, and provide reliable energy solutions for homeowners. As Texas continues to face energy challenges, this innovative initiative offers a promising model for the future of distributed energy and highlights the potential for technology-driven solutions to address pressing environmental and infrastructure issues.

Canada in top 10 for hydropower jobs, but doesn't rank on other renewables

Canada Renewable Energy Jobs rank top 10 in hydropower, says IRENA, but trail in solar PV, wind power, and liquid biofuels; clean tech growth, EV manufacturing, and Canada Infrastructure Bank funding signal broader carbon-neutral opportunities.

 

Key Points

Canada counts 61,130 clean energy roles, top 10 in hydropower, with potential in solar, wind, biofuels, and EV manufacturing.

✅ 61,130 clean energy jobs in Canada per IRENA

✅ Top 10 share in hydropower employment

✅ Growth expected in solar, wind, biofuels, and EVs

 

Canada has made the top 10 list of countries for the number of jobs in hydropower, but didn’t rank in three other key renewable energy technologies, according to new international figures.

Although Canada has only two per cent of the global workforce, it had one of the 10 largest slices of the world’s jobs in hydropower in 2019, says the Abu Dhabi-based International Renewable Energy Agency (IRENA)

Canada didn’t make IRENA’s other top-10 employment lists, for solar photovoltaic (PV) technology, where solar power lags by international standards, liquid biofuels or wind power, released Sept. 30. Figures from the agency show the whole sector represents 61,130 jobs across Canada, or 0.5 per cent of the world’s 11.5 million jobs in renewables.

The numbers show Canada needs to move faster to minimize the climate crisis, including by joining trade blocs that put tariffs on high-carbon goods, argued the Victoria-based BC Sustainable Energy Association after reviewing IRENA’s report. The Canadian Renewable Energy Association also said it showed the country has untapped job creation potential, even as growth projections were scaled back after Ontario scrapped a clean energy program.

But other clean tech advocates say there’s more to the story. When tallying clean energy jobs, it's worth a broader look, Clean Energy Canada argued, pointing to the recent Ford-Unifor deal that includes a $1.8-billion commitment to produce electric vehicles in Oakville, Ont.

Natural Resources Minister Seamus O'Regan’s office also pointed out the renewables employment figures from IRENA are proportional to global population. “While Canada's share of the global clean energy job market is in line with our population size, we produce almost 2.7 per cent of the world’s total primary renewable energy supply. As only 0.5 per cent of the global population, we punch above our weight,” said O'Regan's press secretary, Ian Cameron.

Canada joined IRENA in January 2019 and the country has been described by the association as an “important market” for renewables over the long term.

On Thursday, Prime Minister Justin Trudeau announced a new $10-billion “Growth Plan” to be run by the Canada Infrastructure Bank that would include “$2.5 billion for clean power to support renewable generation and storage and to transmit clean electricity between provinces, territories, and regions, including to northern and Indigenous communities.” The infrastructure bank's plan is expected to create 60,000 jobs, the government said, and in Alberta an Alberta renewables surge could power 4,500 jobs as projects scale up.

World ‘building the renewable energy revolution now’

A powerful renewables sector is not just about job creation. It is also imperative if we are to meet global climate objectives, according to the Intergovernmental Panel on Climate Change. Renewable energy sources have to make up at least a 63 per cent share of the global electricity market by mid-century to battle the more extreme effects of climate change, it said.

“The IRENA report shows that people all over of the world are building the renewable energy revolution now,” said Tom Hackney, policy adviser for the BC Sustainable Energy Association.

“Many people in Canada are doing so, too. But we need to move faster to minimize climate change. For example, at the level of trade policy, a great idea would be to develop low-carbon trading blocs that put tariffs on goods with high embodied carbon emissions.”

Canadian Renewable Energy Association president and CEO Robert Hornung said the IRENA jobs review highlights “significant job creation potential” in Canada. As governments explore how to stimulate economic recovery from the impact of the COVID-19 pandemic, said Hornung, it's important to “capitalize on Canada's untapped renewable energy resources.”

In Canada, 82 per cent of the electricity grid is already non-emitting, noted Sarah Petrevan, policy director for Clean Energy Canada.

With the federal government committing to a 90 per cent non-emitting grid by 2030, said Petrevan, more wind and solar deployment can be expected, even though solar demand has lagged in recent years, especially in the Prairies where renewables are needed to help with Canada’s coal-fired power plant phase out.

One example of renewables in the Prairies, where the provinces are poised to lead growth, is the Travers Solar project, which is expected to be constructed in Alberta through 2021, and is being touted as “Canada's largest solar farm.”

But renewables are only “one part of the broader clean energy sector,” said Petrevan. Clean Energy Canada has outlined how Canada could be electric and clean with the right choices, and has calculated clean tech supports around 300,000 jobs, projected to grow to half a million by 2030.

“We’re talking about a transition of our energy system in every sense — not just in the power we produce. So while the IRENA figures provide global context, they reflect only a portion of both our current reality and the opportunity for Canada,” she said.

The organization’s research has shown that manufacturing of electric vehicles would be one of the fastest-growing job creators over the next decade. Putting a punctuation mark on that is a recent $1.8-billion deal with Ford Motor Company of Canada to produce five models of electric vehicles in Oakville, Ont.

China ‘remains the clear leader’ in renewables jobs

With 4.3 million renewable energy jobs in 2019, or 38 per cent of all renewables jobs, China “remains the clear leader in renewable energy employment worldwide,” the IRENA report states. China has the world's largest population and the second-largest GDP.

The country is also by far the world’s largest emitter of carbon pollution, at 28 per cent of global greenhouse gas emissions, and has significant fossil fuel interests. Chinese President Xi Jinping called for a “green revolution” last month, and pledged to “achieve carbon neutrality before 2060.”

China holds the largest proportion of jobs in hydropower, with 29 per cent of all jobs, followed by India at 19 per cent, Brazil at 11 per cent and Pakistan at five per cent, said IRENA.

Canada, with 32,359 jobs in the industry, and Turkey and Colombia hold two per cent each of the world’s hydropower jobs, while Myanmar and Russia hold three per cent each and Vietnam has four per cent.

China also dominates the global solar PV workforce, with 59 per cent of all jobs, followed by Japan, the United States, India, Bangladesh, Vietnam, Malaysia, Brazil, Germany and the Philippines. There are 4,261 jobs in solar PV in Canada, IRENA calculated, and the country is set to hit a 5 GW solar milestone as capacity expands, out of a global workforce of 3.8 million jobs.

In wind power, China again leads, with 44 per cent of all jobs. Germany, the United States and India come after, with the United Kingdom, Denmark, Mexico, Spain, the Philippines and Brazil following suit. Canada has 6,527 jobs in wind power out of 1.17 million worldwide.

As for liquid biofuels, Brazil leads that industry, with 34 per cent of all jobs. Indonesia, the United States, Colombia, Thailand, Malaysia, China, Poland, Romania and the Philippines fill out the top 10. There are 17,691 jobs in Canada in liquid biofuels.

N.S. senior suspects smart meter to blame for shocking $666 power bill

Nova Scotia Power smart meter billing raises concerns amid estimated billing, catch-up bills, and COVID-19 meter reading delays, after seniors report doubled electricity usage and higher utility charges despite consistent consumption and on-time payments.

 

Key Points

Smart meter billing uses digital reads, limits estimates, and may trigger catch-up charges after reading suspensions.

✅ COVID-19 reading pause led to estimated bills and later catch-ups

✅ Smart meters reduce reliance on estimated billing errors

✅ Customers can seek payment plans and bill reviews

 

A Nova Scotia senior says she couldn't believe her eyes when she opened her most recent power bill. 

Gloria Chu was billed $666 -- more than double what she normally pays, and similar spikes such as rising electricity bills in Calgary have drawn attention.

As someone who always pays her bi-monthly Nova Scotia Power bill in full and on time, Chu couldn't believe it.

According to her bill, her electricity usage almost tripled during the month of May, compared to last year, and is even more than it was last winter, and with some utilities exploring seasonal power rates customers may see confusing swings.

She insists she and her husband aren't doing anything differently -- but one thing has changed.

"I have had a problem since they put the smart meter in," said Chu, who lives in Upper Gulf Shore, N.S.

Chu got a big bill right after the meter was installed in January, too. That one was more than $530.

She paid it, but couldn't understand why it was so high.

As for this bill, she says she just can't afford it, especially amid a recently approved 14% rate hike in Nova Scotia.

"That's all of my CPP," Chu said. "Actually, it's more than my CPP."

Chu says a neighbor up the road who also has a smart meter had her bill double, too. In nearby Pugwash, she says some residents have seen an increase of about $20-$30.

Nova Scotia Power had put a pause on installing smart meters because of the COVID-19 pandemic, but it has resumed as of June 1, with the goal of upgrading 500,000 meters by 2021, even as in other provinces customers have faced fees for refusing smart meters during similar rollouts.

In this case, the utility says it's not the meter that's the problem, and notes that in New Brunswick some old meters gave away free electricity even as the pandemic forced Nova Scotia Power to suspend meter readings for two months.

"As a result, every one of our customers in Nova Scotia received an estimated bill," said Jennifer parker, Nova Scotia Power's director of customer care.

The utility estimated Chu's bill at $182 -- less than she normally pays -- so her latest bill is considered a catch-up bill after meter readings resumed last month.

Parker admits how estimates are calculated isn't perfect.

"There would be a lot of customers who probably had a more accurate bill because of the way that we estimate, and that's actually one of things that smart meters will get rid of, is that we won't need to do estimated billing," Parker said.

Chu isn't quite convinced.

"It is pretty smart for the power company, but it's not smart for us," she said with a laugh.

Nova Scotia Power has put a hold on her bill and says it will work with Chu on an affordable solution, though the province cannot order the utility to lower rates which limits what can be offered.

She just hopes to never see a big bill like this again, while elsewhere in Newfoundland and Labrador a lump-sum electricity credit is being provided to help customers.

Is this the start of an aviation revolution?

Harbour Air Electric Seaplanes pioneer sustainable aviation with battery-electric propulsion, zero-emission operations, and retrofitted de Havilland Beavers using magniX motors for regional commuter routes, cutting fuel burn, maintenance, and carbon footprints across British Columbia.

 

Key Points

Retrofitted floatplanes using magniX battery-electric motors to provide zero-emission, short-haul regional flights.

✅ Battery-electric magniX motors retrofit de Havilland DHC-2 Beavers

✅ Zero-emission, low-noise operations on short regional routes

✅ Lower maintenance and operating costs vs combustion engines

 

Aviation is one of the fastest rising sources of carbon emissions from transport, but can a small Canadian airline show the industry a way of flying that is better for the planet?

As air journeys go, it was just a short hop into the early morning sky before the de Havilland seaplane splashed back down on the Fraser River in Richmond, British Columbia. Four minutes earlier it had taken off from the same patch of water. But despite its brief duration, the flight may have marked the start of an aviation revolution.

Those keen of hearing at the riverside on that cold December morning might have been able to pick up something different amid the rumble of the propellers and whoosh of water as the six-passenger de Havilland DHC-2 Beaver took off and landed. What was missing was the throaty growl of the aircraft’s nine-cylinder radial engine.

In its place was an all-electric propulsion engine built by the technology firm magniX that had been installed in the aircraft over the course of several months. The four-minute test flight (the plane was restricted to flying in clear skies, so with fog and rain closing in the team opted for a short trip) was the first time an all-electric commercial passenger aircraft had taken to the skies.

“It was the first shot of the electric aviation revolution,” says Roei Ganzarski, chief executive of magniX, which worked with Canadian airline Harbour Air Seaplanes to convert one of the aircraft in their fleet of seaplanes so it could run on battery power rather than fossil fuels.

For Greg McDougall, founder of Harbour Air and pilot during the test flight, it marked the culmination of years of trying to put the environment at the forefront of its operations, backed by research investment across the program.

Harbour Air, which has a fleet of some 40 commuter floatplanes serving the coastal regions around Vancouver, Victoria and Seattle, was the first airline in North America to become carbon-neutral through offsets in 2007. A one-acre green roof on their new Victoria airline terminal followed. Then in 2017, 50 solar panels and four beehives housing 10,000 honeybees were added, but for McDougall, a Tesla owner with an interest in disruptive technology, the big goal was to electrify the fleet, with 2023 electric passenger flights as an early target for service.

McDougall searched for alternative motor options for a couple of years and had put the plan on the backburner when Ganzarski first approached him in February 2019. “He said, ‘We’ve got a motor we want to get certified and we want to fly it before the end of the year,’” McDougall recalls.

The two companies found their environmental values and teams were a good match and quickly formed a partnership. Eleven months later, the modest Canadian airline got what McDougall refers to as their “e-plane” off the ground, pulling ahead of other electric flight projects, including those by big-name companies Airbus, Boeing and Rolls-Royce, and startups such as Eviation that later stumbled.

The project came together in record time considering how risk-adverse the aviation industry is, says McDougall. “Someone had to take the lead,” he says. “The reason I live in British Columbia is because of the outdoors: protecting it is in our DNA. When it came to getting the benefits from electric flight it made sense for us to step in and pioneer the next step.”

As the threat posed by the climate crisis deepens, there has been renewed interest in developing electric passenger aircraft as a way of reducing emissions
Electric flight has been around since the 1970s, but it’s remained limited to light-weight experimental planes flying short distances and solar-powered aircraft with enormous wingspans yet incapable of carrying passengers. But as the threat posed by the climate crisis deepens, there has been renewed interest in developing electric passenger aircraft as a way of reducing emissions and airline operating costs, aligning with broader Canada-U.S. collaboration on electrification across transport.

Currently there are about 170 electric aircraft projects underway internationally –up by 50% since April 2018, according to the consulting firm Roland Berger. Many of the projects are futuristic designs aimed at developing urban air taxis, private planes or aircraft for package delivery. But major firms such as Airbus have also announced plans to electrify their own aircraft. It plans to send its E-Fan X hybrid prototype of a commercial passenger jet on its maiden flight by 2021. But only one of the aircraft’s four jet engines will be replaced with a 2MW electric motor powered by an onboard battery.

This makes Harbour Air something of an outlier. As a coastal commuter airline, it operates smaller floatplanes that tend to make short trips up and down the coastline of British Columbia and Washington State, which means its aircraft can regularly recharge their batteries after a point-to-point electric flight along these routes. The company sees itself in a position to retrofit its entire fleet of floatplanes and make air travel in the region as green as possible.

This could bring some advantages. The efficiency of a typical combustion engine for a plane like this is fairly low – a large proportion of the energy from the fuel is lost as waste heat as it turns the propeller that drives the aircraft forward. Electrical motors have fewer moving parts, meaning there’s less maintenance and less maintenance cost, and comparable benefits are emerging for electric ships operating on the B.C. coast as well.

Electrical motors have fewer moving parts, meaning there’s less maintenance and less maintenance cost
Erika Holtz, Harbour Air’s engineering and quality manager, sees the move to electric as the next major aviation advancement, but warns that one stumbling block has been the perception of safety. “Mechanical systems are much better known and trusted,” she says. In contrast people see electrical systems as a bit unknown – think of your home computer. “Turning it off and on again isn’t an option in aviation,” she adds.

But it’s the possibility of spurring lasting change in aviation that’s made working on the Harbour Air/magniX project so exciting for Holtz. Aviation technology has stagnated over the past decades, she says. “Although there have been incremental improvements in certain technologies, there hasn't been a major development change in aviation in 50 years.”

Britain's National Grid Drops China-Based Supplier Over Cybersecurity Fears

National Grid Cybersecurity Component Removal signals NCSC and GCHQ oversight of critical infrastructure, replacing NR Electric and Nari Technology grid control systems to mitigate supply chain risk, cyber threats, and blackout risk.

 

Key Points

A UK move to remove China-linked grid components after NCSC/GCHQ advice, reducing cyber and blackout risks.

✅ NCSC advice to remove NR Electric components

✅ GCHQ-linked review flags critical infrastructure risks

✅ Aims to cut blackout risk and supply chain exposure

 

Britain's National Grid has started removing components supplied by a unit of China-backed Nari Technology's from the electricity transmission network over cybersecurity fears, reflecting a wider push on protecting the power grid across critical sectors.

The decision came in April after the utility sought advice from the National Cyber Security Center (NCSC), a branch of the nation's signals intelligence agency, Government Communications Headquarters (GCHQ), amid campaigns like the Dragonfly campaign documented by Symantec, the newspaper quoted a Whitehall official as saying.

National Grid declined to comment citing "confidential contractual matters." "We take the security of our infrastructure very seriously and have effective controls in place to protect our employees and critical assets, while preparing for an independent operator transition in Great Britain, to ensure we can continue to reliably, safely and securely transmit electricity," it said in a statement.

The report said an employee at the Nari subsidiary, NR Electric Company-U.K., had said the company no longer had access to sites where the components were installed, at a time when utilities worldwide have faced control-room intrusions by state-linked hackers, and that National Grid did not disclose a reason for terminating the contracts.

It quoted another person it did not name as saying the decision was based on NR Electric Company-U.K.'s components that help control and balance the grid, respond to work-from-home demand shifts, and minimize the risk of blackouts.

It was unclear whether the components remained in the electricity transmission network, the report said, amid reports of U.S. power plant breaches that have heightened vigilance.

NR Electric Company-U.K., GCHQ and the Chinese Embassy in London did not immediately respond to requests for comment outside of business hours.

Britain's Department for Energy Security and Net Zero said that it did not comment on the individual business decisions taken by private organizations. "As a government department we work closely with the private sector to safeguard our national security, and to support efforts to fast-track grid connections across the network," it said in a statement.
