IKEA has made a global commitment to reduce the emission of greenhouse gases associated with its use of electricity and energy in their business. In support of this commitment, IKEA Canada has been hard at work to reduce their carbon footprint.
By the end of April 2009 the company will have reduced its energy consumption in its stores by 25% through implementing new practices and technologies. To mark this accomplishment and to show support for their valued global partner, all IKEA stores in Canada will participate in World Wildlife Fund's (WWF) Earth Hour.
WWF's Earth Hour is a global event created to mobilize people around the world to turn their lights off for one hour at 8:30p.m. on Saturday, March 28, to show support for action on climate change.
"IKEA believes that climate change is a major threat to both the environment and people, and CO2 emissions need to be reduced rapidly to prevent real dramatic effects on our climate system." Says Kerri Molinaro, President, IKEA Canada. "We want to be a good example of effective environmental actions and initiatives across our business to help create a better environment for everyone. We call this The IKEA Way."
The IKEA Way is not a new approach for the retailer; IKEA has been committed to the environment for several decades. Whether it is flat-packing products to reduce packaging and reduce transportation emissions, working with Global Charitable partners like WWF, using environmentally responsible materials in its products or having a store format that draws on a larger trade area (instead of more stores), the company has practiced responsible retailing for decades.
Globally, IKEA is cooperating with WWF on several projects to reduce the negative impact on the climate. The aim is to cut carbon dioxide emissions from IKEA suppliers and from passenger traffic to and from the stores.
"WWF and IKEA are both committed to promoting the responsible and sustainable use of natural resources for present and future needs", says Hadley Archer, Director of Business Engagement at WWF-Canada. "We are working together globally to promote responsible forestry and better cotton production, and to address climate change. Working together, more can be achieved."
"At IKEA, we are constantly striving to have a positive impact on the environment in our business. A critical element of our success is to engage our coworkers." says Molinaro.
"We are encouraging all our coworkers to participate in WWF's Earth Hour 2009, both at work and at home. Every one of our 4,000 co-workers in Canada have received an IKEA candle as a symbol of our commitment to responsible environmental practices."
Sulphur Hexafluoride (SF6) Emissions drive rising greenhouse gas impacts in electrical switchgear, power grids, and renewables, with extreme global warming potential, long atmospheric lifetime, and leakage risks challenging climate targets and grid decarbonization.
Key Points
SF6 emissions are leaks from electrical switchgear and grids, a high-GWP gas with ~1,000-year lifetime.
✅ 23,500x CO2 global warming potential (GWP)
✅ Leaks from switchgear, breakers, gas-insulated substations
✅ Clean air and vacuum alternatives emerging for MV/HV
Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents.
But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road.
Levels are rising as an unintended consequence of the green energy boom and the broader global energy transition worldwide.
Cheap and non-flammable, SF6 is a colourless, odourless, synthetic gas. It makes a hugely effective insulating material for medium and high-voltage electrical installations.
It is widely used across the industry, from large power stations to wind turbines to electrical sub-stations in towns and cities.
It prevents electrical accidents and fires.
However, the significant downside to using the gas is that it has the highest global warming potential of any known substance. It is 23,500 times more warming than carbon dioxide (CO2).
Just one kilogram of SF6 warms the Earth to the same extent as 24 people flying London to New York return.
It also persists in the atmosphere for a long time, warming the Earth for at least 1,000 years.
So why are we using more of this powerful warming gas?
The way we make electricity around the world is changing rapidly, with New Zealand's push to electrify in its energy system.
Where once large coal-fired power stations brought energy to millions, the drive to combat climate change and to move away from coal means they are now being replaced by mixed sources of power including wind, solar and gas.
This has resulted in many more connections to the electricity grid, and with EU electricity use could double by 2050, a rise in the number of electrical switches and circuit breakers that are needed to prevent serious accidents.
Collectively, these safety devices are called switchgear. The vast majority use SF6 gas to quench arcs and stop short circuits.
"As renewable projects are getting bigger and bigger, we have had to use it within wind turbines specifically," said Costa Pirgousis, an engineer with Scottish Power Renewables on its new East Anglia wind farm, which doesn't use SF6 in turbines.
"As we are putting in more and more turbines, we need more and more switchgear and, as a result, more SF6 is being introduced into big turbines off shore.
"It's been proven for years and we know how it works, and as a result it is very reliable and very low maintenance for us offshore."
How do we know that SF6 is increasing?
Across the entire UK network of power lines and substations, there are around one million kilograms of SF6 installed.
A study from the University of Cardiff found that across all transmission and distribution networks, the amount used was increasing by 30-40 tonnes per year.
This rise was also reflected across Europe with total emissions from the 28 member states in 2017 equivalent to 6.73 million tonnes of CO2. That's the same as the emissions from 1.3 million extra cars on the road for a year.
Researchers at the University of Bristol who monitor concentrations of warming gases in the atmosphere say they have seen significant rises in the last 20 years.
"We make measurements of SF6 in the background atmosphere," said Dr Matt Rigby, reader in atmospheric chemistry at Bristol.
"What we've seen is that the levels have increased substantially, and we've seen almost a doubling of the atmospheric concentration in the last two decades."
How does SF6 get into the atmosphere?
The most important means by which SF6 gets into the atmosphere is from leaks in the electricity industry.
Electrical company Eaton, which manufactures switchgear without SF6, says its research indicates that for the full life-cycle of the product, leaks could be as high as 15% - much higher than many other estimates.
Louis Schaeffer, electrical business manager at Eaton, said: "The newer gear has very low leak rates but the key question is do you have newer gear?
"We looked at all equipment and looked at the average of all those leak rates, and we didn't see people taking into account the filling of the gas. Plus, we looked at how you recycle it and return it and also included the catastrophic leaks."
How damaging to the climate is this gas?
Concentrations in the atmosphere are very small right now, just a fraction of the amount of CO2 in the air.
However, the global installed base of SF6 is expected to grow by 75% by 2030, as data-driven electricity demand surges worldwide.
Another concern is that SF6 is a synthetic gas and isn't absorbed or destroyed naturally. It will all have to be replaced and destroyed to limit the impact on the climate.
Developed countries are expected to report every year to the UN on how much SF6 they use, but developing countries do not face any restrictions on use.
Right now, scientists are detecting concentrations in the atmosphere that are 10 times the amount declared by countries in their reports. Scientists say this is not all coming from countries like India, China and South Korea.
One study found that the methods used to calculate emissions in richer countries "severely under-reported" emissions over the past two decades.
Why hasn't this been banned?
SF6 comes under a group of human-produced substances known as F-gases. The European Commission tried to prohibit a number of these environmentally harmful substances, including gases in refrigeration and air conditioning, back in 2014.
But they faced strong opposition from industries across Europe.
"In the end, the electrical industry lobby was too strong and we had to give in to them," said Dutch Green MEP Bas Eickhout, who was responsible for the attempt to regulate F-gases.
"The electric sector was very strong in arguing that if you want an energy transition, and you have to shift more to electricity, you will need more electric devices. And then you also will need more SF6.
"They used the argument that otherwise the energy transition would be slowed down."
What do regulator and electrical companies say about the gas?
Everyone is trying to reduce their dependence on the gas, and US control efforts suggest targeted policies can drive declines, as it is universally recognised as harmful to the climate.
In the UK, energy regulator Ofgem says it is working with utilities to try to limit leaks of the gas.
"We are using a range of tools to make sure that companies limit their use of SF6, a potent greenhouse gas, where this is in the interest of energy consumers," an Ofgem spokesperson told BBC News.
"This includes funding innovation trials and rewarding companies to research and find alternatives, setting emissions targets, rewarding companies that beat those targets, and penalising those that miss them."
Are there alternatives - and are they very expensive?
The question of alternatives to SF6 has been contentious over recent years.
For high-voltage applications, experts say there are very few solutions that have been rigorously tested.
"There is no real alternative that is proven," said Prof Manu Haddad from the school of engineering at Cardiff University.
"There are some that are being proposed now but to prove their operation over a long period of time is a risk that many companies don't want to take."
Medium voltage operations there are several tried-and-tested materials. Some in the industry say that the conservative nature of the electrical industry is the key reason that few want to change to a less harmful alternative.
"I will tell you, everyone in this industry knows you can do this; there is not a technical reason not to do it," said Louis Schaffer from Eaton.
"It's not really economic; it's more a question that change takes effort and if you don't have to, you won't do it."
Some companies are feeling the winds of change
Sitting in the North Sea some 43km from the Suffolk coast, Scottish Power Renewables has installed one of world's biggest wind farms, in line with a sustainable electric planet vision, where the turbines will be free of SF6 gas.
East Anglia One will see 102 of these towering generators erected, with the capacity to produce up to 714MW (megawatts) of power by 2020, enough to supply half a million homes.
Previously, an installation like this would have used switchgear supplied with SF6, to prevent the electrical accidents that can lead to fires.
Each turbine would normally have contained around 5kg of SF6, which, if it leaked into the atmosphere, would add the equivalent of around 117 tonnes of carbon dioxide. This is roughly the same as the annual emissions from 25 cars.
"In this case we are using a combination of clean air and vacuum technology within the turbine. It allows us to still have a very efficient, reliable, high-voltage network but to also be environmentally friendly," said Costa Pirgousis from Scottish Power Renewables.
"Once there are viable alternatives on the market, there is no reason not to use them. In this case, we've got a viable alternative and that's why we are using it."
But even for companies that are trying to limit the use of SF6, there are still limitations. At the heart of East Anglia One sits a giant offshore substation to which all 102 turbines will connect. It still uses significant quantities of the highly warming gas.
What happens next ?
The EU will review the use of SF6 next year and will examine whether alternatives are available. However, even the most optimistic experts don't think that any ban is likely to be put in place before 2025.
Yukon Renewable Energy Funding backs wind turbines, grid-scale battery storage, and transmission line upgrades, cutting diesel dependence, lowering greenhouse gas emissions, and strengthening Yukon Energy's isolated grid for remote communities, local jobs, and future growth.
Key Points
Federal support for Yukon projects adding wind, battery storage, and grid upgrades to cut diesel use and emissions.
✅ Three 100 kW wind turbines will power Destruction Bay.
✅ 8 MW battery storage smooths peaks and reduces diesel.
✅ Mayo-McQuesten 138 kV line upgrade boosts reliability.
Kluane First Nation in Yukon will receive a total of $3.1 million in funding from the federal government to install and operate wind turbines that will help reduce the community’s diesel reliance.
According to a release, the community will integrate three 100-kilowatt turbines in Destruction Bay, Yukon, providing a renewable energy source for their local power grid that will reduce greenhouse gas emissions and create local jobs in the community.
A $2-million investment from Natural Resources Canada came from the Clean Energy for Rural and Remote Communities Program, part of the Government of Canada’s Investing in Canada infrastructure plan, which supports green energy solutions across jurisdictions. Crown-Indigenous Relations’ and Northern Affairs Canada also contributed a $1.1-million investment from the Northern REACHE Program.
Also, the Government of Canada announced more than $39.2 million in funding for two Yukon Energy projects that will increase the reliability of Yukon’s electrical grid, including exploration of a potential connection to the B.C. grid to bolster resiliency, and help build the robust energy system needed to support future growth. The investment comes from the government’s Green Infrastructure Stream (GIS) of the Investing in Canada infrastructure plan.
Project 1: Grid-scale battery storage
The federal government is investing $16.5 million in Yukon Energy’s construction of a new battery storage system in Yukon. Once completed, the 8 MW battery will be the largest grid-connected battery in the North, and one of the largest in Canada, alongside major Ontario battery projects underway.
The new battery is a critical investment in Yukon Energy’s ability to meet growing demands for power and securing Yukon’s energy future. As an isolated grid, one of the largest challenges Yukon Energy faces is meeting peak demands for power during winter months, as electrification grows with EV adoption in the N.W.T. and beyond.
When complete, the new system will store excess electricity generated during off-peak periods, complementing emerging vehicle-to-grid integration approaches, and provide Yukoners with access to more power during peak periods. This new energy storage system will create a more reliable power supply and help reduce the territory’s reliance on diesel fuel. Over the 20-year life of project, the new battery is expected to reduce carbon emissions in Yukon by more than 20,000 tonnes.
A location for the new battery energy storage system has not been identified. Yukon Energy will begin permitting of the project in 2020 with construction targeted to be complete by mid-2023.
Project 2: Replacing and upgrading the Mayo to McQuesten Transmission Line
Yukon Energy has received $22.7 million in federal funding to proceed with Stage 1 of the Stewart to Keno City Transmission Project – replacing and upgrading the 65 year-old transmission line between Mayo and McQuesten. The project also includes the addition of system protection equipment at the Stewart Crossing South substation. The Yukon government, through the Yukon Development Corporation, has already provided $3.5 million towards planning for the project.
Replacing the Mayo to McQuesten transmission line is critical to Yukon Energy’s ability to deliver safe and reliable electricity to customers in the Mayo and Keno regions, mirroring broader regional transmission initiatives that enhance grid resilience, and to support economic growth in Yukon. The transmission line has reached end-of-life and become increasingly unreliable for customers in the area.
The First Nation of Na-Cho Nyak Dun has expressed their support of this project. The project has also been approved by the Yukon Environmental and Socio-Economic Assessment Board.
Yukon Energy will begin replacing and upgrading the 31 km transmission line between Mayo and McQuesten in 2020. Construction is expected to be complete in late 2020. When finished, the new 138 kV transmission line will provide more reliable electricity to customers in the Mayo and Keno regions and be equipped to support industrial growth and development in the area, including the Victoria Gold Mine, with renewable power from the Yukon grid.
Planning work for the remainder of the Stewart to Keno City Transmission Project has been completed. Yukon Energy continues to explore funding opportunities that are needed to proceed with other stages of the project.
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.
Manitoba Crypto Mining Electricity Pause signals a moratorium to manage grid strain, Manitoba Hydro capacity, infrastructure costs, and electricity rates, while policymakers evaluate sustainable energy demand, and planning for data centers and blockchain operations.
Key Points
A temporary halt on mining power hookups in Manitoba to assess grid impacts, protect rates, and plan sustainable use.
✅ Applies only to new service requests; existing sites unaffected
✅ Enables review with Manitoba Hydro for sustainable policy
The Manitoba government has temporarily suspended approving new electricity service connections for cryptocurrency mining operations, a step similar to BC Hydro's suspension seen in a neighboring province.
The Original Pause
The pause was initially imposed in November 2022 due to concerns that the rapid influx of cryptocurrency mining operations could place significant strain on the province's electrical grid. Manitoba Hydro, the province's primary electric utility, which has also faced legal scrutiny in the Sycamore Energy lawsuit, warned that unregulated expansion of the industry could necessitate billions of dollars in infrastructure investments, potentially driving up electricity rates for Manitobans.
The Extended Pause Offers Time for Review
The extension of the pause is meant to provide the government and Manitoba Hydro with more time to assess the situation thoroughly and develop a long-term solution addressing the challenges and opportunities presented by cryptocurrency mining, including evaluating emerging options such as modular nuclear reactors that other jurisdictions are studying. The government has stated its commitment to ensuring that the long-term impacts of the industry are understood and don't unintentionally harm other electricity customers.
What Does the Pause Mean?
The pause does not affect existing cryptocurrency operations but prevents the establishment of new ones. It applies specifically to requests for electricity service that haven't yet resulted in agreements to construct infrastructure or supply electricity, and it comes amid regional policy shifts like Alberta ending its renewable moratorium that also affect grid planning.
Concerns About Energy Demands
Cryptocurrency mining involves running high-powered computers around the clock to solve complex mathematical problems. This process is incredibly energy-intensive. Globally, the energy consumption of cryptocurrency networks has drawn scrutiny for its environmental impact, with examples such as Iceland's mining power use illustrating the scale. In Manitoba, concern focuses on potentially straining the electrical grid and making it difficult for Manitoba Hydro to plan for future growth.
Other Jurisdictions Taking Similar Steps
Manitoba is not alone in its cautionary approach to cryptocurrency mining. Several other regions and utilities have implemented restrictions or are exploring limitations on how cryptocurrency miners can access electricity, including moves by Russia to ban mining amid power deficits. This reflects a growing awareness among policymakers about the potentially destabilizing impact this industry could have on power grids and electricity markets.
Finding a Sustainable Path Forward
Manitoba Hydro has stated that it is open to working with cryptocurrency operations but emphasizes the need to do so in a way that protects existing ratepayers and ensures a stable and reliable electricity system for all Manitobans, while recognizing market uncertainties highlighted by Alberta wind project challenges in a neighboring province. The government's extension of the pause signifies its intention to find a responsible path forward, balancing the potential for economic development with the necessity of safeguarding the province's power supply.
IRENA Climate Investment Platform accelerates renewable energy financing through de-risking, bankable projects, and public-private partnerships, advancing Paris Agreement goals via grid integration, microgrids, and decarbonization while expanding access, jobs, and sustainable economic growth.
Key Points
A global platform linking bankable renewable projects with finance, derisking and partners to scale decarbonization.
✅ Connects developers with banks, funds, and insurers
✅ Promotes de-risking via policy, PPAs, and legal frameworks
✅ Targets Paris goals with grid, microgrids, and off-grid access
The heads-of-state and energy ministers from more than 120 nations just met in Abu Dhabi and they had one thing in common: a passion to increase the use of renewable energy to reduce the threat from global warming — one that will also boost economic output and spread prosperity. Access to finance, though, is critical to this goal.
Indeed, the central message to emerge from the conference hosted by the International Renewable Energy Agency (IRENA) this week in the United Arab Emirates is that a global energy transition is underway that has the potential to revitalize economies and to lift people out of poverty. But such a conversion requires international cooperation and a common desire to address the climate cause.
“The renewable energy sector created jobs employing 11 million people in 2019 and provided off-grid solutions, having helped bring the number of people with no access to electricity to under 1 billion,” the current president of the UN General Assembly Tiijani Muhammad-Bande of Nigeria told the audience.
Today In: Business While renewables are improving energy access and reducing inequities, they also have the potential to curb CO2 emissions globally. The goal is to shrink them by 45% by 2030 and 90% by 2050, with Canada's net-zero race highlighting the role of renewable energy in achieving those targets. Getting there, though, requires progressive government policies that will help to attract financing.
According to IRENA, investment in the clean energy sector is now at $330 billion a year. But if the 2050 goals are to be reached, those levels must nearly double to $750 billion annually. The green energy sector does not want to compete with the oil and gas sectors but rather, it is seeking to diversify fuel sources — a strategy that could help make electricity systems more resilient to climate risks. To hit the Paris agreement’s targets, it says that renewable energy deployment must increase by a factor of six.
To that end, IRENA is forming a “climate investment platform” that will bring ideas to the table and then introduce prospective parties. It will focus on those projects that it believes are “bankable.”
It’s about helping project developers find banks, private companies and pension funds to finance their worthy projects, IRENA Director General Francesco La Camera said in response to this reporter’s question. Moreover, he said that the platform would work to ensure there is a sound legal structure and that there is legislative support to “de-risk” the investments.
“Overcoming investment needs for energy transformation infrastructure is one of the most notable barriers to the achievement of national goals,” La Camera says. “Therefore, the provision of capital to support the adoption of renewable energy is key to low-carbon sustainable economic development and plays a central role in bringing about positive social outcomes.”
If the monies are to flow into new projects, governments have to create an environment where innovation is to be rewarded: tax incentives for renewables along with the design and implementation of transition plans. The aim is to scale up which in turn, leads to new jobs and greater economic productivity — a payback of three-to-seven times the initial investment.
The path of least resistance, for now, is off-grid green energy solutions, or providing electricity to rural areas by installing solar panels that may connect to localized microgrids. Africa, which has a half-billion people without reliable electricity, would benefit. However, “If you want to go to scale and have bankable projects, you have to be connected to the grid,” Moira Wahba, with the UN Development Program, told this writer. “That requires large capital and private enterprise.”
Public policy must thus work to create the knowledge base and the advocacy to help de-risk the investments. Government’s role is to reassure investors that they will not be subject to arbitrary laws or the crony allocation of contracts. Risk takers know there are no guarantees. But they want to compete on a level playing.
Analyzing Risk Profiles

[+]ABU DHABI SUSTAINABILITY WEEK How do foreign investors square the role of utilities that are considered safe and sound with their potential expansion into new fields such as investing in carbon-free electricity and in new places? The elimination of risk is not possible, says Mohamed Jameel Al Ramahi, chief executive officer of UAE-based Masdar. But the need to decarbonize is paramount. The head of the renewable energy company says that every jurisdiction has its own risk profile but that each one must be fully transparent while also properly structuring their policies and regulations. And there needs to be insurance for political risks.
The United States and China, for example, are already “de-risked,” because they are deploying “gigawatts of renewables,” he told this writer. “When we talk about doubling the amount of needed investment, we have to take into account the risk profile of the whole world. If it is a high-risk jurisdiction, it will be difficult to bring in foreign capital.”
The most compelling factor that will drive investment is whether the global community can comply with the Paris agreement, says Dr. Thani Ahmed Al Zeyoudi, Minister of the Ministry of Climate Change and the Environment for the United Arab Emirates. The goal is to limit increases to 2 degrees Celsius by mid-century, with the understanding that the UN’s latest climate report emphasizes that positive results are urgently needed.
One of the most effective mechanisms is the public-private model. Governments, for example, are signing long-term power purchase agreements, giving project developers the necessary income they need to operate, and in the EU plans to double electricity use by 2050 are reinforcing these commitments. They can also provide grants and bring in international partners such as the World Bank.
“We are seeing the impact of climate change with the various extreme events: the Australian fires, the cyclones and the droughts,” the minister told reporters. “We can no longer pass this to future generations to deal with.”
The United Arab Emirates is not just talking about it, adds Sultan Al Jabber, chief executive of Abu Dhabi’s national oil company, Adnoc, who is also the former head of subsidiary Masdar. It is acting now, and across Europe Big Oil is turning electric as traditional players pivot too. His comments came during Abu Dhabi’s Sustainability Week at the World Future Energy Summit. The country is “walking the walk” by investing in renewable projects around the globe and it is growing its own green energy portfolio. Addressing climate change is “right” while it is also making “perfect economic sense.”
The green energy transition has taken root in advanced economies while it is making inroads in the developing world — a movement that has the twin effect of addressing climate change and creating economic opportunities, and one that aligns with calls to transform into a sustainable electric planet for long-term prosperity. But private investment must double, which requires proactive governments to limit unnecessary risks and to craft the incentives to attract risk-takers.
E.ON Digital Transformer Stations modernize distribution grids with smart grid monitoring, voltage control, and remote switching, enabling bidirectional power flow, renewables integration, and rapid fault isolation from centralized grid control centres.
✅ Real-time voltage and current data along feeders and laterals
✅ Remote switching cuts outage duration and truck rolls
✅ Supports renewables and bidirectional power flows
E.ON plans to commission 2500 digital transformer stations in the service areas of its four German distribution grid operators - Avacon, Bayernwerk, E.DIS and Hansewerk - by the end of 2019. Starting this year, E.ON will solely install digital transformer stations in Germany, aligning with 2019 grid edge trends seen across the sector. This way, the digital grid is quite naturally being integrated into E.ON's distribution grids.
With these transformer stations as the centrepiece of the smart grid, it is possible to monitor and control using synchrophasors in the power grid from the grid control centre. This helps to maintain a more balanced utilisation of the grid and, with increasing complexity, ensures continued security of supply.
Until now, the current and voltage parameters required for safe grid operation could usually only be determined at the beginning of a power line, where there is usually a grid substation in place. Controlling current flow and voltage in the downstream system was physically impossible.
In the future, grids will have to function in both directions: they will bring electricity to the customer while at the same time collecting and transmitting more and more green electricity via HVDC technology where appropriate. This requires physical data to be made available along the entire route. To ensure security of supply, voltage fluctuations must be kept within narrowly defined limits and the current flow must not exceed the specified value, while reducing line losses with superconducting cables remains an important consideration. To manage this challenge, it is necessary to install digital technology.
The possibility of remotely controlling grids also reduces downtimes in the event of faults and supports a smarter electricity infrastructure approach. With the new technology, our grid operators can quickly and easily access the stations of the affected line. The grid control centres can thus limit and eliminate faults on individual line sections within a very short space of time.
