NEW YORK —
U.S. Homeland Security Secretary Tom Ridge recently urged private industry to do its part to secure the Internet infrastructure that has become critical to national and economic security.
Speaking before a gathering of executives at the National Cyber Security Summit in Santa Clara, Calif., Ridge warned the United States' reliance on computers has made cyber targets attractive to terrorists, and that they are well aware that "a few lines of code could ultimately wreak as much havoc as a handful of bombs."
"Everything from electricity grids to banking transactions to telecommunications depends on secure, reliable cyber networks," Ridge said. "The continued success of protecting our cyberspace depends on the investment and commitment of each of you and the businesses you represent."
The private sector owns 85 per cent of the country's critical infrastructure, including the computer networks that underlie them, security department officials said. As such, the agency's cyber security division has sought to build a public-private sector alliance that will drive improvements in security practices in both the private and public sectors as well as among average computer users, while co-ordinating efforts to respond to cyber crises.
The agency's efforts are guided by the Bush administration's February "National Strategy to Secure Cyberspace," which set goals for government and industry, but rejected the idea of new government regulations.
Several members of Congress have since floated proposals to mandate minimum security requirements, including one by Congressman Adam Putnam that would require public companies to undergo third-party cyber-security audits and report results to the U.S. Securities and Exchange Commission.
Assistant secretary Robert Liscouski, also speaking at the summit, promised to advocate for industry against regulation, but warned that if the private sector fails to step up to the responsibility, legislation will naturally follow.
"If that's what you want, I promise that's what you will get," he said.
In October, the department staged a cyber-war game that simulated an attack on computers, banks and utilities. The event showed communication was not smooth enough between the agencies, Ridge said.
The department is looking to improve crisis response, while studying how critical infrastructures are dependent on cyberspace, U.S. Cyber Security director Amit Yoran said.
Duke Energy Net Metering Proposal updates rooftop solar compensation with time-of-use rates, lower grid credits, and a minimum charge, aligning payments with electricity demand in North Carolina pending regulators' approval.
Key Points
A plan to swap flat credits for time-of-use rates and a minimum charge for rooftop solar customers in North Carolina.
✅ Time-of-use credits vary by grid demand
✅ $10 minimum use charge plus $14 basic fee
✅ Aims to align solar payouts with actual electricity value
Duke Energy has proposed new rules for how owners of rooftop solar panels are paid for electricity they send to the electric grid. It could mean more complexity and lower payments, but the utility says rates would be fairer.
State legislators have called for changes in the payment rules — known as "net metering" policies that allow households to sell power back to energy firms.
Right now, solar panel owners who produce more electricity than they need get credits on their bills, equal to whatever they pay for electricity. Under the proposed changes, the credit would be lower and would vary according to electricity demand, said Duke spokesperson Randy Wheeless.
"So in a cold winter morning, like now, you would get more, but maybe in a mild spring day, you would get less," Wheeless said Tuesday. "So, it better reflects what the price of electricity is."
Besides setting rates by time of use, solar owners also would have to pay a minimum of $10 a month for electricity, even if they don't use any from the grid. That's on top of Duke's $14 basic charge. Duke said it needs the extra revenue to pay for grid infrastructure to serve solar customers.
The proposal is the result of an agreement between Duke and solar industry groups — the North Carolina Sustainable Energy Association; the Southern Environmental Law Center, which represented Vote Solar and the Southern Alliance for Clean Energy; solar panel maker Sunrun Inc.; and the Solar Energy Industries Association.
The deal is similar to one approved by regulators in South Carolina last year, while in Nova Scotia a solar charge was delayed after controversy.
Daniel Brookshire of the North Carolina Sustainable Energy Association said he hopes the agreement will help the solar industry.
"We reached an agreement here that we think will provide certainty over the next decade, at least, for those interested in pursuing solar for their homes, and for our members who are solar installers," Brookshire said.
But other environmental and consumer groups oppose the changes, amid debates over who pays for grid upgrades elsewhere. Jim Warren with NC WARN said the rules would slow the expansion of rooftop solar in North Carolina.
"It would make it even harder for ordinary people to go solar," Warren said. "This would make it more complicated and more expensive, even for wealthier homeowners."
State regulators still must approve the proposal, even as courts weigh aspects of the electricity monopoly in related solar cases. If state regulators approve it, rates for new net metering customers would take effect Jan. 1, 2023.
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.
EU Electricity Market Reform advances two-way CfDs, PPAs, and fixed-price tariffs to cut volatility, support renewables and nuclear, stabilize investor revenues, and protect consumers from price spikes across wholesale power markets.
Key Points
An EU plan expanding two-way CfDs, PPAs, and fixed-price contracts to curb price swings and support low-carbon power.
✅ Two-way CfDs return excess revenues to consumers
The European Union wants to expand the use of contracts that pay power plants a fixed price for electricity, a draft proposal showed, as part of an electricity market revamp to shield European consumers from big price swings.
The European Commission pledged last year to reform the EU's electricity market rules, after record-high gas prices, caused by cuts to Russian flows, sent power prices soaring, prompting debates over gas price cap strategies in response.
A draft of the EU executive's proposal, seen by Reuters on Tuesday and due to be published on Mar. 16, steered clear of the deep redesign of the electricity market that some member states have called for, even as nine EU countries opposed sweeping reforms as a fix earlier in the crisis, suggesting instead limited changes to nudge countries towards more predictable, fixed-price power contracts.
If EU countries want to support new investments in wind, solar, geothermal, hydropower and nuclear electricity, for example - a point over which France and Germany have wrestled - they should use a two-way contract for difference (CfD) or an equivalent contract, the draft said.
The aim is to provide a stable revenue stream to investors, and help make consumers' energy bills less volatile, even though rolling back electricity prices is tougher than it appears. Restricting this support to renewable and low-carbon electricity also aims to speed up Europe's shift away from fossil fuels.
Two-way CfDs offer generators a fixed "strike price" for their electricity, regardless of the price in short-term energy markets. If the market price is above the CfD strike price, then the extra revenue the generator receives should be handed out to final electricity consumers, the draft EU document said.
Countries should also make it easier for power buyers to sign power purchase agreements (PPA) - another type of long-term contract to directly buy electricity from a generator.
Governments should also make sure consumers have access to fixed-price electricity contracts - echoing France's new electricity pricing scheme to reassure Brussels - giving them the option to avoid a contract that would expose them to volatile prices swings in energy markets, the draft said.
If European energy prices were to spike to extreme levels again, the Commission suggested allowing national governments to temporarily intervene to fix prices while weighing emergency measures to limit prices where needed, and offer consumers and small businesses a share of their electricity at a lower price.
B.C. EV Electrification 2055 projects grid capacity needs doubling to 37 GW, driven by electric vehicles, renewable energy expansion, wind and solar generation, limited natural gas, and policy mandates for zero-emission transportation.
Key Points
A projection that electrifying all B.C. road transport by 2055 would more than double grid demand to 37 GW.
✅ Site C adds 1.1 GW; rest from wind, solar, limited natural gas.
✅ Electricity price per kWh rises 9%, but fuel savings offset.
✅ Significant GHG cuts with 93% renewable grid under Clean Energy Act.
Researchers at the University of Victoria say that if B.C. were to shift to electric power for all road vehicles by 2055, the province would require more than double the electricity now being generated.
The findings are included in a study to be published in the November issue of the Applied Energy journal.
According to co-author and UVic professor Curran Crawford, the team at the university's Pacific Institute for Climate Solutions took B.C.'s 2015 electrical capacity of 15.6 gigawatts as a baseline, and added projected demands from population and economic growth, then added the increase that shifting to electric vehicles would require, while acknowledging power supply challenges that could arise.
They calculated the demand in 2055 would amount to 37 gigawatts, more than double 15.6 gigawatts used in 2015 as a baseline, and utilities warn of a potential EV charging bottleneck if demand ramps up faster than infrastructure.
"We wanted to understand what the electricity requirements are if you want to do that," he said. "It's possible — it would take some policy direction."
B.C. announces $4M in rebates for home and work EV charging stations across the province
The team took the planned Site C dam project into account, but that would only add 1.1 gigawatts of power. So assuming no other hydroelectric dams are planned, the remainder would likely have to come from wind and solar projects and some natural gas.
"Geothermal and biomass were also in the model," said Crawford, adding that they are more expensive electricity sources. "The model we were using, essentially, we're looking for the cheapest options."

The electricity bill, per kilowatt hour, would increase by nine per cent, according to the team's research, but Crawford said getting rid of the gasoline and diesel now used to fuel vehicles could amount to an overall cost saving, especially when combined with zero-emission vehicle incentives available to consumers.
The province introduced a law this year requiring that all new light-duty vehicles sold in B.C. be zero emission by 2040, while the federal 2035 EV mandate adds another policy signal, so the researchers figured 2055 was a reasonable date to imagine all vehicles on the road to be electric.
Crawford said hydrogen-powered vehicles weren't considered in the study, as the model used was already complicated enough, but hydrogen fuel would actually require more electricity for the electrolysis, when compared to energy stored in batteries.
Electric vehicles are approaching a tipping point as faster charging becomes more available — here's why
The study also found that shifting to all-electric ground transportation in B.C. would also mean a significant decrease in greenhouse gas emissions, assuming the Clean Energy Act remains in place, which mandates that 93 per cent of grid electricity must come from renewable resources, whereas nationally, about 18 per cent of electricity still comes from fossil fuels, according to 2019 data.
"Doing the electrification makes some sense — If you're thinking of spending some money to reduce carbon emissions, this is a pretty cost effective way of doing that," said Crawford.
European Green Deal Electrification accelerates decarbonization via renewables, electric vehicles, heat pumps, and clean industry, backed by sustainable finance, EIB green lending, just transition funds, and energy taxation reform to phase out fossil fuels.
Key Points
An EU plan to replace fossil fuels with renewable electricity in transport, buildings, and industry, supported by green finance.
✅ Doubles electricity's share to cut CO2 and phase out fossil fuels.
✅ Drives EVs, heat pumps, and electrified industry via renewables.
✅ Funded by EIB lending, EU budget, and just transition support.
The European Union is preparing an ambitious plan to completely decarbonize by 2050. Increasing the share of electricity in Europe’s energy system – electricity that will increasingly come from renewable sources - will be at the center of this strategy, aligning with the broader global energy transition under way, the new head of the European Commission’s energy department said yesterday.
This will mean more electric cars, electric heating and electric industry. The idea is that fossil fuels should no longer be a primary energy source, heating homes, warming food or powering cars. In the medium term they should only be used to generate electricity, a shift mirrored by New Zealand's electricity shift efforts, which then powers these things, resulting in less CO2 emissions.
“First assessments show we need to double the share of electricity in energy consumption by 2050,” Ditte Juul-Jørgensen said at an event in Brussels this week, a goal echoed by recent calls to double investment in power systems from world leaders. “We’ve already seen an increase in the last decade, but we need to go further”.
Juul-Jørgensen, who started in her job as director-general of the commission’s energy department in August, has come to the role at a pivotal time for energy. The 2050 decarbonization proposal from the Commission, the EU’s executive branch, is expected to be approved next month by EU national leaders. A veto from Poland that has blocked adoption until now is likely to be overcome if Poland and other Eastern European countries are offered financial assistance from a “just transition fund”, according to EU sources.
Ursula von der Leyen, the incoming President of the Commission, has promised to unveil a “European Green Deal” in her first 100 days in office designed to get the EU to its 2050 goal. Juul-Jørgensen will be working with the incoming EU Energy Commissioner, Kadri Simson, on designing this complex strategy. The overall aim will be to phase out fossil fuels, and increase the use of electricity from green sources, amid trends like oil majors pivoting to electric across Europe today.
“This will be about how do we best make use of electricity to feed into other sectors,” Juul-Jørgensen said. “We need to think about transforming it into other sources, and how to best transport it.”
“But the biggest challenge from what I see today is that of investment and finance - the changes we have to make are very significant.”
Financing problems
The Commission is going to try to tackle the challenges of financing the energy transition with two tools: dedicated climate funding in the EU budget, and dedicated climate lending from the European Investment Bank.
“The EIB will play an increasing role in future. We hope to see agreement [with the EIB board] on that in the coming months so there’s a clear operator in the EIB to support the green transition. We’re looking at something around €400 billion a year.”
The Commission’s proposed dedicated climate spending in the next seven-year budget must still be approved by the 28 EU national governments. Juul-Jørgensen said there is unanimous agreement on the amount: 25% of the budget. But there is disagreement about how to determine what is green spending.
“A lot of work has been ongoing to ensure that when it comes to counting it reflects the reality of the investments,” she said. “We’re working on the taxonomy on sustainable finance - internally identifying sectors contributing to overall climate objectives.”
Electricity pact
Juul-Jørgensen was speaking at an event organized by the the Electrification Alliance, a pact between nine industry organizations to lobby for electricity to be put at the heart of the European green deal. They signed a declaration at the event calling for a variety of measures to be included in the green deal, reflecting debates over a fully renewable grid by 2030 in other jurisdictions, including a change to the EU’s energy taxation regime which incentivizes a switch from fossil fuel to electricity consumption.
“Electrification is the most important solution to turn the vision of a fossil-free Europe into reality,” said Laurence Tubiana, CEO of the European Climate Foundation, one of the signatories, and co-architect of the Paris Agreement.
“We are determined to deliver, but we must be mindful of the different starting points and secure sufficient financing to ensure a fair transition”, said Magnus Hall, President of electricity industry association Eurelectric, another signatory.
The energy taxation issue has been particularly tricky for the EU, since any change in taxation rules requires the unanimous consent of all 28 EU countries. But experts say that current taxation structures are subsidizing fossil fuels and punishing electricity, as recent UK net zero policy changes illustrate, and unless this is changed the European Green Deal can have little effect.
“Yes this issue will be addressed in the incoming commission once it takes up its function,” Juul-Jørgensen said in response to an audience question. “We all know the challenge - the unanimity requirement in the Council - and so I hope that member states will agree to the direction of work and the need to address energy taxation systems to make sure they’re consistent with the targets we’ve set ourselves.”
But some are concerned that the transformation envisioned by the green deal will have negative impacts on some of the most vulnerable members of society, including those who work in the fossil fuel sector.
This week the Centre on Regulation in Europe sent an open letter to Frans Timmermans, the Commission Vice President in charge of climate, warning that they need to be mindful of distributional effects. These worries have been heightened by the yellow vest protests in France, which were sparked by French President Emmanuel Macron’s attempt to increase fuel taxes for non-electric cars.
“The effectiveness of climate action and sustainability policies will be challenged by increasing social and political pressures,” wrote Máximo Miccinilli, the center’s director for energy. “If not properly addressed, those will enhance further populist movements that undermine trust in governance and in the public institutions.”
Miccinilli suggests that more research be done into identifying, quantifying and addressing distributional effects before new policies are put in place to phase out fossil fuels. He proposes launching a new European Observatory for Distributional Effects of the Energy Transition to deal with this.
EU national leaders are expected to vote on the 2050 decarbonization target, building on member-state plans such as Spain's 100% renewable electricity goal by mid-century, at a summit in Brussels on December 12, and Von der Leyen will likely unveil her European Green Deal in March.
BC Hydro 2021 Peak Load Records highlight record-breaking electricity demand, peak load spikes, heat dome impacts, extreme cold, and shifting work-from-home patterns managed by a flexible hydroelectric system and climate-driven load trends.
Key Points
Record-breaking electricity demand peaks from extreme heat and cold that reshaped daily load patterns across BC in 2021.
✅ Heat dome and deep freeze drove sustained peak electricity demand
✅ Peak load built gradually, reflecting work-from-home behavior
✅ Flexible hydroelectric system adapts quickly to demand spikes
From June’s heat dome to December’s extreme cold, 2021 was a record-setting year, according to BC Hydro, and similar spikes were noted as Calgary's electricity use surged in frigid weather.
On Friday, the energy company released a new report on electricity demand, and how extreme temperatures over extended periods of time, along with growing scrutiny of crypto mining electricity use, led to record peak loads.
“We use peak loads to describe the electricity demand in the province during the highest load hour of each day,” Kyle Donaldson, BC Hydro spokesperson, said in a media release.
“With the heat dome in the summer and the sustained cold temperatures in December, we saw more record-breaking hours on more days last year than any other single year.”
According to BC Hydro, during summer, the Crown corporation recorded 19 of its top 25 all-time summer daily peak records — including breaking its all-time summer peak hourly demand record.
In December, which saw extremely cold temperatures and heavy snowfall, BC Hydro said its system experienced the highest and longest sustained load levels ever, as it activated its winter payment plan to assist customers.
Overall, BC Hydro says it has experienced 11 of its top 25 all-time daily peak records this winter, adding that Dec. 27 broke its all-time high peak hourly demand record.
“BC Hydro’s hydroelectric system is directly impacted by variations in weather, including drought conditions that require adaptation, and in 2021 more electricity demand records were broken than any other year prior, largely because of the back-to-back extreme temperatures lasting for days and weeks on end,” reads the report.
The energy company expects this trend to continue, noting that it has broken the peak record five times in the past five years, and other jurisdictions such as Quebec consumption record have also shattered consumption records.
It also noted that peak demand patterns have also changed since the first year of the COVID-19 pandemic, with trends seen during Earth Hour usage offering context.
“When the previous peak hourly load record was broken in January 2020, load displayed sharper increases and decreases throughout the day, suggesting more typical weather and behaviour,” said the report.
“In contrast, the 2021 peak load built up more gradually throughout the day, suggesting more British Columbians were likely working from home, or home for the holidays – waking up later and home earlier in the evening – as well as colder weather than average.”
BC Hydro also said “current climate models suggest a warming trend continuing in years to come which could increase demand year-round,” but noted that its flexible hydroelectric system can meet changes in demand quickly.
