A massive energy source in Canada is casting a long shadow over legislation in Maine to determine the future course of power transmission through the state.
The source is Hydro-Quebec, a utility owned by the provincial government, which is trying to obtain the generation capacity of its counterpart provincial utility in New Brunswick, New Brunswick Power.
Hydro-Quebec's purchase has lingered over discussion during legislative hearings on L.D. 1786, a bill that would steer energy transmission corridors to designated state-owned land, giving the state oversight to ensure how the projects would benefit Maine.
With access to New Brunswick's grid, Hydro-Quebec could be poised to build a corridor across the border into Maine and flood the state and regional U.S. markets with subsidized hydroelectric power, several lawmakers have said.
Hydro-Quebec now produces 41,000 megawatts of energy, even before considering the capacity of New Brunswick power, which produces 4,000 megawatts from nuclear, hydroelectric, coal, oil and diesel sources. This production dwarfs Maine's current energy demand of 2,200 megawatts and production capacity of about 3,400 megawatts.
By 2015, 4,000 megawatts of Hydro-Quebec's capacity will come from wind power. New Brunswick Power is also expanding its wind capacity.
During hearings on the corridor bill, Rep. Ken Fletcher, R-Winslow, raised concerns that Hydro-Quebec's current energy exports — which were only 8 percent of its production in 2008 — produced almost one-third of its profits that year.
"Isn't it reasonable for them to expect that they could send their 4,000 megawatts of wind and combine it with their hydro, and probably control the market?" said Fletcher, a member of the Legislature's Utilities and Energy Committee.
Some state officials, however, don't see Hydro-Quebec's growing capacity as a problem — they see it as a solution.
John Kerry, the director of the Office of Energy Independence and Security, said steady Canadian hydroelectric capacity could balance Maine's production of wind energy.
"I think we should work collaboratively with our Canadian neighbors," Kerry said in an interview. "I underscore that we should do it at arm's length and be prudent, but we should see it as an opportunity."
For its part, Hydro-Quebec said that its wind capacity, aside from about 150 megawatts for Massachusetts and Connecticut, is for Quebec consumption, and hydroelectric power like that in Hydro-Quebec's portfolio does not qualify for valuable renewable energy certificates, or RECs, traded in New England.
"The wind developers or the solar developers in New England should not fear the presence of Hydro-Quebec in the market, because we are not going after the REC market," said Christian Brosseau, president of Hydro-Quebec US.
Furthermore, Brosseau said, Hydro-Quebec would not undercut the electricity market in the northeastern U.S. with cheap hydroelectricity, because it would sell at the marginal wholesale rate.
The corridor bill being considered, however, would allow the company to tap into the Maine grid and potentially the larger, lucrative regional market if it entered into a long-term contract favorable to Maine ratepayers and industry.
"Anything that makes sense we'll look at seriously but there's no commitment that yes we will be building certainly in the next 10 years in Maine," Brosseau said. "But we will be looking at it."
Lawmakers are again scheduled to review the corridor legislation in a work session at Burton M. Cross building in Augusta, across from the State House.
Berkshire Hathaway Energy Wind Power drives cheap electricity rates in Iowa via utility-scale wind turbines, integrated transmission, battery storage, and grid management, delivering renewable energy, stable pricing, and long-term rate freezes through 2028.
Key Points
A vertically integrated wind utility lowering Iowa rates via owned generation, transmission, and advanced grid control.
✅ Owned wind assets meet Iowa residential demand
✅ Integrated transmission lowers costs and losses
✅ Rate freeze through 2028 sustains cheap power
In his latest letter to Berkshire Hathaway shareholders, Warren Buffett used the 20th anniversary of Berkshire Hathaway Energy to tout its cheap electricity bills for customers.
When Berkshire purchased the majority share of BHE in 2000, the cost of electricity for its residential customers in Iowa was 8.8 cents per kilowatt-hour (kWh) on average. Since then, these electricity rates have risen at a paltry <1% per year, with a freeze on rate hikes through 2028. As anyone who pays an electricity bill knows, that is an incredible deal.
As Buffett himself notes with alacrity, “Last year, the rates [BHE’s competitor in Iowa] charged its residential customers were 61% higher than BHE’s. Recently, that utility received a rate increase that will widen the gap to 70%.”
The Winning Strategy
So, what’s Buffett’s secret to cheap electricity? Wind power.
“The extraordinary differential between our rates and theirs is largely the result of our huge accomplishments in converting wind into electricity,” Buffett explains.
Wind turbines in Iowa that BHE owns and operates are expected to generate about 25.2 million megawatt-hours (MWh) of electricity for its customers, as projects like Building Energy operations begin to contribute. By Buffett’s estimations, that will be enough to power all of its residential customers’ electricity needs in Iowa.
The company has plans to increase its renewable energy generation in other regions as well. This year, BHE Canada is expected to start construction on a 117.6MW wind farm in Alberta, Canada with its partner, Renewable Energy Systems, that will provide electricity to 79,000 homes in Canada’s oil country.
But I would argue that the secret to BHE’s success perhaps goes deeper than transitioning to sources of renewable energy. There are plenty of other utility companies that have adopted wind and solar power as an energy source. In the U.S., where renewable electricity surpassed coal in 2022, at least 50% of electricity customers have the option to buy renewable electricity from their power supplier, according to the Department of Energy. And some states, such as New York, have gone so far as to allow customers to pick from providers who generate their electricity.
What differentiates BHE from a lot of the competition in the utility space is that it owns the means to generate, store, transmit and supply renewable power to its customers across the U.S., U.K. and Canada, with lessons from the U.K. about wind power informing policy.
In its financial filings for 2019, the company reported that it owns 33,600MW of generation capacity and has 33,400 miles of transmission lines, as well as a 50% interest in Electric Transmission Texas (ETT) that has approximately 1,200 miles of transmission lines. This scale and integration enables BHE to be efficient in the distribution and sale of electricity, including selling renewable energy across regions.
BHE is certainly not alone in building renewable-energy fueled electricity dominions. Its largest competitor, NextEra, built 15GW of wind capacity and has started to expand its utility-scale solar installations. Duke Energy owns and operates 2,900 MW of renewable energy, including wind and solar. Exelon operates 40 wind turbine sites across the U.S. that generate 1,500 MW.
Integrated Utilities Power Ahead
It’s easy to see why utility companies see wind as a competitive source of electricity compared to fossil fuels. As I explained in my previous post, Trump’s Wrong About Wind, the cost of building and generating wind energy have fallen significantly over the past decade. Meanwhile, improvements in battery storage and power management through new technological advancements have made it more reliable (Warren Buffett bet on that one too).
But what is also striking is that integrated power and transmission enables these utility companies to make those decisions; both in terms of sourcing power from renewable energy, as well as the pricing of the final product. Until wind and solar power are widespread, these utility companies are going to have an edge of the more fragmented ends of the industry who can’t make these purchasing or pricing decisions independently.
Warren Buffett very rarely misses a beat. He’s not the Oracle of Omaha for nothing. Berkshire Hathaway’s ownership of BHE has been immensely profitable for its shareholders. In the year ended December 31, 2019, BHE and its subsidiaries reported net income attributable to BHE shareholders of $2.95 billion.
There’s no question that renewable energy will transform the utility industry over the next decade. That change will be led by the likes of BHE, who have the power to invest, control and manage their own energy generation assets.
Alberta Hydropower Potential highlights renewable energy, dams, reservoirs, grid flexibility, contrasting wind and solar growth with limited investment, regulatory hurdles, river basin resources, and decarbonization pathways across Athabasca, Peace, and Slave River systems.
Key Points
It is the technical capacity for new hydro in Alberta's river basins to support a more reliable, lower carbon grid.
✅ 42,000 GWh per year developable hydro identified in studies.
✅ Major potential in Athabasca, Peace, and Slave River basins.
✅ Barriers include high capital costs, market design, water rights.
When you think about renewable energy sources on the Prairies, your mind may go to the wind farms in southern Alberta, or even the Travers Solar Project, southeast of Calgary.
Most of the conversation around renewable energy in the province is dominated by advancements in solar and wind power, amid Alberta's renewable energy surge that continues to attract attention.
But what about Canada's main source of electricity — hydro power?
More than half of Canada's electricity is generated from hydro sources, with 632.2 terawatt-hours produced as of 2019. That makes it the fourth largest installed capacity of hydropower in the world.
But in Alberta, it's a different story.
Currently, hydro power contributes between three and five per cent of Alberta's energy mix, while fossil fuels make up about 89 per cent.
According to Canada's Energy Future report from the Canada Energy Regulator, by 2050 it will make up two per cent of the province's electricity generation shares.
So why is it that a province so rich in mountains and rivers has so little hydro power?
Hydro's history in Alberta
Hydro power didn't always make up such a small sliver of Alberta's electricity generation. Hydro installations began in the early 20th century as the province's population exploded.
Grant Berg looks after engineering for hydro for TransAlta, Alberta's largest producer of hydro power with 17 facilities across the province.
"Our first plant was Horseshoe, which started in 1911 that we formed as Calgary Power," he said.
"It was really in response to the City of Calgary growing and having some power needs."
Berg said in 1913, TransAlta's second installation, the Kananaskis Plant, started as Calgary continued to grow.

Some bigger installations were built in the 1920s, including Ghost reservoir, but by mid-century population growth increased.
"Quite a large build out really, I think in response to the growth in Alberta following the war. So through the 1950s really quite a large build out of hydro from there."
By the 1950s, around half of the province's installed capacity was hydro power.
"Definitely Calgary power was all hydro until the 1950s," said Berg.
Hydro potential in the province
Despite the current low numbers in hydroelectricity, Alberta does have potential.
According to a 2010 study, there is approximately 42,000 gigawatt-hours per year of remaining developable hydroelectric energy potential at identified sites.
An average home in Alberta uses around 7,200 kilowatt-hours of electricity per year, meaning that the hydro potential could power 5.8 million homes each year.
"This volume of energy could be sufficient to serve a significant amount of Alberta's load and therefore play a meaningful role in the decarbonization of the province's electric system," the Alberta Electric System Operator said in its 2022 Pathways to Net-Zero Emissions report.
Much of that potential lies in northern Alberta, in the Athabasca, Peace and Slave River basins.
The AESO report says that despite the large resource potential, Alberta's energy-only market framework has attracted limited investment in hydroelectric generation.
Hydro power was once a big deal in Alberta, but investment in the industry has been in decline since the 1950s. Climate change reporter Christy Climenhaga explains why.
So why does Alberta leave out such a large resource potential on the path to net zero?
The government of Alberta responded to that question in a statement.
"Hydro facilities, particularly large scale ones involving dams, are associated with high costs and logistical demands," said the Ministry of Affordability and Utilities.
"Downstream water rights for other uses, such as irrigation, further complicate the development of hydro projects."
The ministry went on to say that wind and solar projects have increased far more rapidly because they can be developed at relatively lower cost and shorter timelines, and with fewer logistical demands.
"Sources from wind power and solar are increasingly more competitive," said Jean-Denis Charlebois, chief economist with the Canadian Energy Regulator.
Hydro on the path to net zero
Hydro power is incredibly important to Canada's grid, and will remain so, despite growth in wind and solar power across the province.
Charlebois said that across Canada, the energy make-up will depend on the province.
"Canadian provinces will generate electricity in very different ways from coast to coast. The major drivers are essentially geography," he said.
Charlebois says that in British Columbia, Manitoba, Quebec and Newfoundland and Labrador, hydropower generation will continue to make up the majority of the grid.
"In Alberta and Saskatchewan, we see a fair bit of potential for wind and solar expansion in the region, which is not necessarily the case on Canada's coastlines," he said.
And although hydro is renewable, it does bring its adverse effects to the environment — land use changes, changes in flow patterns, fish populations and ecosystems, which will have to be continually monitored.
"You want to be able to manage downstream effects; make sure that you're doing all the proper things for the environment," said Ryan Braden, director of mining and hydro at TransAlta.
Braden said hydro power still has a part to play in Alberta, even with its smaller contributions to the future grid.
"It's one of those things that, you know, the wind doesn't blow or the sun doesn't shine, this is here. The way we manage it, we can really support that supply and demand," he said.
BC Hydro Air Conditioning Efficiency Tips help cut energy bills as HVAC use rises. Avoid inefficient portable AC units, set thermostats near 25 C, use fans and window shading, and turn systems off when unoccupied.
Key Points
BC Hydro's guidelines to lower summer power bills by optimizing A/C settings, fans, shading, and usage habits at home.
✅ Set thermostats to 25 C; switch off A/C when away
✅ Prefer fans and window shading; close doors/windows in heat
BC Hydro is scolding British Columbians for their ineffective, wasteful and costly use of home air conditioners.
In what the electric utility calls “not-so-savvy” behaviour, it says many people are over-spending on air conditioning units that are poorly installed or used incorrectly.
"The majority of British Columbians will spend more time at home this summer because of the COVID-19 pandemic," BC Hydro says in a news release about an August survey of customers.
"With A/C use on the rise, there is evidence British Columbians are not cooling down efficiently, leading to higher summer electricity bills, as extreme heat boosts U.S. bills too this summer."
BC Hydro estimates some customers are shelling out $200 more on their summer energy bills than they need to during a record-breaking 2021 demand year for electricity.
The pandemic is compounding the demand for cool, comfortable air at home. Roughly two in five British Columbians between the ages of 25 and 50 are working from home five days a week.
However, it’s not just COVID-19 that is putting a strain on energy consumption and monthly bills, with drought affecting generation as well today.
About 90 per cent of people who use an air conditioner set it to a temperature below the recommended 25 Celsius, according to BC Hydro.
In fact, one in three people have set their A/C to the determinedly unseasonable temperature of 19 C.
Another 30 per cent are using more than one portable air conditioning unit, which the utility says is considered the most inefficient model on the market, and questions remain about crypto mining electricity use in B.C. today.
The use of air conditioners is steadily increasing in B.C. and has more than tripled since 2001, according to BC Hydro, with all-time high demand also reported in B.C. during recent heat waves. The demand for climate control is particularly high among condo-dwellers since apartments tend to trap heat and stay warmer.
This may explain why one in 10 residents of the Lower Mainland has three portable air conditioning units, and elsewhere Calgary's frigid February surge according to Enmax.
In addition, 30 per cent of people keep the air conditioning on for the sake of their pets while no one is home.
BC Hydro makes these recommendations to save energy and money on monthly bills while still keeping homes cooled during summer’s hottest days, and it also offers a winter payment plan to help manage costs:
Cool homes to 25 C in summer months when home; air conditioning should be turned off when homes are unoccupied.
In place of air conditioning, running a fan for nine hours a day over the summer costs $7.
Shading windows with drapes and blinds can help insulate a home by keeping out 65 per cent of the heat.
If the temperature outside a home is warmer than inside, keep doors and windows closed to keep cooler air inside.
Use a microwave, crockpot or toaster oven to avoid the extra heat produced by larger appliances, such as an oven, when cooking. Hang clothes to dry instead of using a dryer on hot days.
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 Power Market Overhaul targets soaring electricity prices by decoupling gas from power, boosting renewables, refining price caps, and stabilizing grids amid inflation, supply shocks, droughts, nuclear outages, and intermittent wind and solar.
Key Points
EU plan to redesign electricity pricing, curb gas-driven costs, boost renewables, and protect consumers from volatility.
✅ Decouples power prices from marginal gas generation
✅ Caps non-gas revenues to fund consumer relief
✅ Supports grid stability with storage, demand response, LNG
While energy prices are soaring around the world, Europe is in a particularly tight spot. Its heavy dependence on Russian gas -- on top of droughts, heat waves, an unreliable fleet of French nuclear reactors and a continent-wide shift to greener but more intermittent sources like solar and wind -- has been driving electricity bills up and feeding the highest inflation in decades. As Europe stands on the brink of a recession, and with the winter heating season approaching, officials are considering a major overhaul of the region’s power market to reflect the ongoing shift from fossil fuels to renewables.
1. How is electricity priced? Unlike oil or natural gas, there’s no efficient way to save lots of electricity to use in the future, though projects to store electricity in gas pipes are emerging. Commercial use of large-scale batteries is still years away. So power prices have been set by the availability at any given moment. When it’s really windy or sunny, for example, then more is produced relatively cheaply and prices are lower. If that supply shrinks, then prices rise because more generators are brought online to help meet demand -- fueled by more expensive sources. The way the market has long worked is that it is that final technology, or type of plant, needed to meet the last unit of consumption that sets the price for everyone. In Europe this year, that has usually meant natural gas.
2. What is the relationship between power and gas? Very close. Across western Europe, gas plants have been a vital part of the energy infrastructure for decades, with Irish price spikes highlighting dispatchable power risks, fed in large part by supplies piped in from Siberia. Gas-fired plants were relatively quick to build and the technology straightforward, at least compared with nuclear plants and burns cleaner than coal. About 18% of Europe’s electricity was generated at gas plants last year; in 2020 about 43% of the imported gas came from Russia. Even during the depths of the Cold War, there’d never been a serious supply problem -- until the relationship with Russia deteriorated this year after it invaded Ukraine. Diversifying away from Russia, such as by increasing imports of liquefied natural gas, requires new infrastructure that takes a lot of time and money.
3. Why does it work this way? In theory, the relationship isn’t different from that with coal, for example. But production hiccups and heatwave curbs on plants from nuclear in France to hydro in Spain and Norway significantly changed the generation picture this year, and power hit records as plants buckled in the heat. Since coal-fired and nuclear plants are generally running all the time anyway, gas plants were being called upon more often -- at times just to keep the lights on as summer temperatures hit records. And with the war in Ukraine resulting in record gas prices, that pushed up overall production costs. It’s that relationship that has made the surging gas price the driver for electricity prices. And since the continent is all connected, it has pushed up prices across the region. The value of the European power market jumped threefold last year, to a record 836 billion euros ($827 billion today).
4. What’s being considered? With large parts of European industry on its knees and households facing jumps in energy bills of several hundred percent, as record electricity prices ripple through markets, the pressure on governments and the European Union to intervene has never been higher. One major proposal is to impose a price cap on electricity from non-gas producers, with the difference between that and the market price channeled to relief for consumers. While it sounds simple, any such changes would rip up a market design that’s worked for decades and could threaten future investments because of unintended consequences.
5. How did this market evolve? The Nordic region and the British market were front-runners in the 1990s, then Germany followed and is now the largest by far. A trader can buy and sell electricity delivered later on same day in blocks of an hour or even down to 15-minute periods, to meet sudden demand or take advantage of price differentials. The price for these contracts is decided entirely by the supply and demand, how much the wind is blowing or which coal plants are operating, for example. Demand tends to surge early in the morning and late afternoon. This system was designed when fossil fuels provided the bulk of power. Now there are more renewables, which are less predictable, with wind and solar surpassing gas in EU generation last year, and the proposed changes reflect that shift.
6. What else have governments done? There are also traders who focus on longer-dated contracts covering periods several years ahead, where broader factors such as expected economic output and the extent to which renewables are crowding out gas help drive prices. This year’s wild price swings have prompted countries including Germany, Sweden and Finland to earmark billions of euros in emergency liquidity loans to backstop utilities hit with sudden margin calls on their trading.
BC Hydro COVID-19 Bill Relief offers pandemic support with bill credits, rate cuts, and deferred payments for residential, small business, and industrial customers across B.C., easing utilities costs during COVID-19 economic hardship.
Key Points
COVID-19 bill credits, a rate cut, and deferred payments for eligible B.C. homes, small businesses, and industrial customers.
✅ Non-repayable credits equal to 3 months of average bills.
✅ Small businesses closed can skip bills for three months.
✅ Large industry may defer 50% of electricity costs.
B.C. residents who have lost their jobs or had their wages cut will get a three-month break on BC Hydro bills, while small businesses, amid commercial consumption plummets during COVID-19, are also eligible to apply for similar relief.
Premier John Horgan said Wednesday the credit for residential customers will be three times a household’s average monthly bill over the past year and does not have to be repaid as part of the government’s support package during the COVID-19 pandemic, as BC Hydro demand down 10% highlights the wider market pressures.
He said small businesses that are closed will not have to pay their power bills for three months, and in Ontario an Ontario COVID-19 hydro rebate complemented similar relief, and large industrial customers, including those operating mines and pulp mills, can opt to have 50 per cent of their electricity costs deferred, though a deferred costs report warned of long-term liabilities.
BC Hydro rates will be cut for all customers by one per cent as of April 1, a move similar to Ontario 2021 rate reductions that manufacturers supported lower rates at the time, after the B.C. Utilities Commission provided interim approval of an application the utility submitted last August.
Eligible residential customers can apply for bill relief starting next week and small business applications will be accepted as of April 14, while staying alert to BC Hydro scam attempts during this period, with the deadline for both categories set at June 30.
