The 1.5 million-ton-per-annum (TPA) biomass co-firing facility to be built at the Drax power station in Yorkshire, United Kingdom, will be one of the largest units of its type in the world.

The project, expected to be complete in 2011, will generate 400 megawatts (MW) of the 4,000 MW power station's output and is part of a commitment by Drax to reduce CO2 emissions by 15%.

Alstom Power has been awarded the $98 million engineering, procurement and construction contract to build the main processing works contract by Drax. The works will receive, handle, store and process various biomass materials ready for direct injection into the power station's coal-fired boilers. Alstom has global project experience in supplying biomass co-firing technology to large-scale coal-fired power plants.

Contracts for the direct injection equipment and the rail unloading facility will be awarded by Drax by the end of 2008. Site preparation has begun and construction is due to start in the second half of the year. Phase I of the project will be commissioned toward the end of 2009.

In 2007, Drax produced 22.5 million tons of CO2 and hopes to save 10% of the total emissions by the biomass co-firing technology burning wood pellets, which could be sourced from North America. Drax is also making good progress with the current turbine upgrade project, which, combined with the co-firing benefit, could see a 15% reduction of CO2 emissions by 2011.

The company will benefit from income from the UK's renewable obligation certificates scheme that guarantees income from power generated using renewable energy sources. Drax will also be able to reduce the number of CO2-emissions permits it has to purchase under the European Union's emissions-trading scheme.

Covid-19 is reshaping the electric rhythms of New York City

COVID-19 Electricity Demand Shift flattens New York's load curve, lowers peak demand, and reduces wholesale prices as NYISO operators balance the grid amid stay-at-home orders, rising residential usage, cheap natural gas, and constrained renewables.

 

Key Points

An industry-wide change in load patterns: flatter peaks, lower prices, and altered grid operations during lockdowns.

✅ NYISO operators sequestered to maintain reliable grid control

✅ Morning and evening peaks flatten; residential use rises mid-day

✅ Wholesale prices drop amid cheap natural gas and reduced demand

 

At his post 150 miles up the Hudson, Jon Sawyer watches as a stay-at-home New York City stirs itself with each new dawn in this era of covid-19.

He’s a manager in the system that dispatches electricity throughout New York state, keeping homes lit and hospitals functioning, work that is so essential that he, along with 36 colleagues, has been sequestered away from home and family for going on four weeks now, to avoid the disease, a step also considered for Ontario power staff during COVID-19 measures.

The hour between 7 a.m. and 8 a.m. once saw the city bounding to life. A sharp spike would erupt on the system’s computer screens. Not now. The disease is changing the rhythms of the city, and, as this U.S. grid explainer notes, you can see it in the flows of electricity.

Kids are not going to school, restaurants are not making breakfast for commuters, offices are not turning on the lights, and thousands if not millions of people are staying in bed later, putting off the morning cup of coffee and a warm shower.

Electricity demand in a city that has been shut down is running 18 percent lower at this weekday morning hour than on a typical spring morning, according to the New York Independent System Operator, Sawyer’s employer. As the sun rises in the sky, usage picks up, but it’s a slower, flatter curve.

Though the picture is starkest in New York, it’s happening across the country. Daytime electricity demand is falling, even accounting for the mild spring weather, and early-morning spikes are deflating, with similar patterns in Ontario electricity demand as people stay home. The wholesale price of electricity is falling, too, driven by both reduced demand and the historically low cost of natural gas.

As covid-19 hits, coal companies aim to cut the tax they pay to support black-lung miners

Falling demand will hit the companies that run the “merchant generators” hardest. These are the privately owned power plants that sell electricity to the utilities and account for about 57 percent of electricity generation nationwide.

Closed businesses have resulted in falling demand. Residential usage is up — about 15 percent among customers of Con Edison, which serves New York City and Westchester County — as workers and schoolchildren stay home, while in Canada Hydro One peak rates remain unchanged for self-isolating customers, but it’s spread out through the day. Home use does not compensate for locked-up restaurants, offices and factories. Or for the subway system, which on a pre-covid-19 day used as much electricity as Buffalo.

Hospitals are a different story: They consume twice as much energy per square foot as hotels, and lead schools and office buildings by an even greater margin. And their work couldn’t be more vital as they confront the novel coronavirus.

Knowing that, Sawyer said, puts the ordinary routines of his job, which rely on utility disaster planning, the things about it he usually takes for granted, into perspective.

“Keeping the lights on: It comes to the forefront a little more when you understand, ‘I’m going to be sequestered on site to do this job, it’s so critical,’” he said, speaking by phone from his office in East Greenbush, N.Y., where he has been living in a trailer, away from his family, since March 23.

Sawyer, 53, is a former submariner in the U.S. Navy, so he has experience when it comes to being isolated from friends and family for long periods. Many of his colleagues in isolation, who all volunteered for the duty, also are military veterans, and they’re familiar with the drill. Life in East Greenbush has advantages over a submarine — you can go outside and throw a football or Frisbee or walk or run the trail on the company campus reserved for the operators, and every day you can use FaceTime or Skype to talk with your family.

His wife understood, he said, though “of course it’s a sacrifice.” But she grasped the obligation he felt to be there with his colleagues and keep the power on.

“It’s a new world, it’s definitely an adjustment,” said Rich Dewey, the system’s CEO, noting that America’s electricity is safe for now. “But we’re not letting a little virus slow us down.”

There are 31 operators, two managers and four cooks and cleaners all divided between East Greenbush, which handles daytime traffic, and another installation just west of Albany in Guilderland, which works at night. The operators work 12-hour shifts every other day.

Computers recalibrate generation, statewide, to equal demand, digesting tens of thousands of data points, every six seconds. Other computers forecast the needs looking ahead 2½ hours. The operators monitor the computers and handle the “contingencies” that inevitably arise.

They dispatch the electricity along transmission lines ranging from 115,000 volts to 765,000 volts, much of it going from plants and dams in western and northern New York downstate toward the city and Long Island.

They always focus on: “What is the next worse thing that can happen, and how can we respond to that?” Sawyer said.

It’s the same shift and the same work they’ve always done, and that gives this moment an oddly normal feeling, he said. “There’s a routine to it that some of the people working at home now don’t have.”

Medical workers check in with them daily to monitor their physical health and mental condition. So far, there have been no dropouts.

Cheap oil doesn’t mean much when no one’s going anywhere

Statewide, the daily demand for electricity has fallen nearly 9 percent.

The distribution system in New England is looking at a 3 to 5 percent decline; the Mid-Atlantic states at 5 to 7 percent; Washington state at 10 percent; and California by nearly as much. In Texas, demand is down 2 percent, “but even there you’re still seeing drops in the early-morning hours,” said Travis Whalen, a utility analyst with S&P Global Platts.

In the huge operating system that embraces much of the middle of the country, usage has fallen more than 8 percent — and the slow morning surge doesn’t peak until noon.

In New York, there used to be a smaller evening spike, too (though starting from a higher load level than the one in the morning). But that’s almost impossible to see anymore because everyone isn’t coming home and turning on the lights and TV and maybe throwing a load in the laundry all at once. No one goes out, either, and the lights aren’t so bright on Broadway.

California, in contrast, had a bigger spike in the evening than in the morning before covid-19 hit; maybe some of that had to do with the large number of early risers spreading out the morning demand and highlighting electricity inequality that shapes access. Both spikes have flattened but are still detectable, and the evening rise is still the larger.

Only at midnight, in New York and elsewhere, does the load resemble what it used to look like.

The wholesale price of electricity has fallen about 40 percent in the past month, according to a study by S&P Global Platts. In California it’s down about 30 percent. In a section covered by the Southwest Power Pool, the price is down 40 percent from a year ago, and in Indiana, electricity sold to utilities is cheaper than it has been in six years.

Some of the merchant generators “are going to be facing some rather large losses,” said Manan Ahuja, also an analyst with S&P Global Platts. With gas so cheap, coal has built up until stockpiles average a 90-day supply, which is unusually large. Ahuja said he believes renewable generators of electricity will be especially vulnerable because as demand slackens it’s easier for operators to fine-tune the output from traditional power plants.

Bravado, dread and denial as oil-price collapse hits the American fracking heartland

As Dewey put it, speaking of solar and wind generators, “You can dispatch them down but you can’t dispatch them up. You can’t make the wind blow or the sun shine.”

Jason Tundermann, a vice president at Level 10 Energy, which promotes renewables, argued that before the morning and evening spikes flattened they were particularly profitable for fossil fuel plants. He suggested electricity demand will certainly pick up again. But an issue for renewable projects under development is that supply chain disruptions could cause them to miss tax credit deadlines.

With demand “on pause,” as Sawyer put it, and consumption more evenly spread through the day, the control room operators in East Greenbush have a somewhat different set of challenges. The main one, he said, is to be sure not to let those high-voltage transmission lines overload. Nuclear power shows up as a steady constant on the real-time dashboard; hydropower is much more up and down, depending on the capacity of transmission lines from the far northern and western parts of the state.

Some human habits are more reliably fixed. The wastewater that moves through New York City’s sewers — at a considerably slower pace than the electricity in the nearby wires — hasn’t shown any change in rhythm since the coronavirus struck, according to Edward Timbers, a spokesman for the city’s Department of Environmental Protection. People may be sleeping a little later, but the “big flush” still arrives at the wastewater treatment plants, about three hours or so downstream from the typical home or apartment, every day in the late morning, just as it always has.

APS asks customers to conserve energy after recent blackouts in California

Arizona Energy Conservation Alert urges APS and TEP customers to curb usage during a heatwave, preventing rolling blackouts, easing peak demand, and supporting grid reliability by raising thermostats, delaying appliances, and pausing pool pumps.

 

Key Points

A utility request during extreme heat to cut demand and protect grid reliability, helping prevent outages.

✅ Raise thermostats to 80 F or higher during peak hours

✅ Delay washers, dryers, dishwashers until after 8 p.m.

✅ Pause pool pumps; switch off nonessential lights and devices

 

After excessive heat forced rolling blackouts for thousands of people across California Friday and Saturday, Arizona Public Service Electric is asking customers to conserve energy this afternoon and evening.

“Given the extended heat wave in the western United States and climate-related grid risks that utilities are monitoring, APS is asking customers to conserve energy due to extreme energy demand that is driving usage higher throughout the region with today’s high temperatures,” APS said in a statement.

Tucson Electric Power has made a similar request of customers in its coverage area.


APS is asking customers to conserve energy in the following ways Tuesday until 8 p.m.:

  • Raise thermostat settings to no lower than 80 degrees.
  • Turn off extra lights and avoid use of discretionary major appliances such as clothes washers, dryers and dishwashers.
  • Avoid operation of pool pumps.

The request from APS also came just hours after Arizona Corporation Commission Chairman Bob Burns sent a letter to electric utilities under the commission's umbrella, like APS, to see if they are in good shape or anticipate any problems given looming shortages in California. He requested the companies respond by noon Friday.


"The whole plan is to take a look at the system early in the Summer," Burns said. "Early May we look at the system, make sure we're ready and able to serve the public throughout the entire heat cycle."

Burns told ABC15 the Summer Preparedness workshop with utilities took place in May and the regulated utilities reported they were well equipped to meet the anticipated peaks of the Summer, even as supply-chain pressures mount across the industry. Tuesday's letter to the electric companies seeks to see if they are still able to "adequately, safely and reliably" serve customers through the heatwave, or if what happened in California could take place here.

"With the activities that are occurring over in California, including tight grid conditions that have repeatedly tested operators, we just want to double check," Burns said.

An APS representative told ABC15 they have adequate supply and reserve and don't anticipate any problems.

However, the rolling blackouts in California also caught the attention of Commissioner Lea Marquez Peterson. She is calling on the chairman to hold an emergency meeting amid wildfire concerns across California and the region.

"The risk to Arizonans and the fact that energy could be interrupted, that we had some kind of rolling blackout like California would have, would be really a public health issue," Peterson said. "It could be life and death in some cases for vulnerable populations."

Energy Vault Lands $110M From SoftBank’s Vision Fund for Gravity Storage

Energy Vault Gravity Storage uses crane-stacked concrete blocks to deliver long-duration, grid-scale renewable energy; a SoftBank Vision Fund-backed, pumped-hydro analog enabling baseload power and a lithium-ion alternative with proprietary control algorithms.

 

Key Points

Gravity-based cranes stack blocks to store and dispatch power for hours, enabling grid-scale, low-cost storage.

✅ 4 MW/35 MWh modules; ~9-hour duration

✅ Estimated $200-$250/kWh; lower LCOE than lithium-ion

✅ Backed by SoftBank Vision Fund; Cemex and Tata support

 

Energy Vault, the Swiss-U.S. startup that says it can store and discharge electrical energy through a super-sized concrete-and-steel version of a child’s erector set, has landed a $110 million investment from Japan’s SoftBank Vision Fund to take its technology to commercial scale.

Energy Vault, a spinout of Pasadena-based incubator Idealab and co-founded by Idealab CEO and billionaire investor Bill Gross, unstealthed in November with its novel approach to using gravity to store energy.

Simply put, Energy Vault plans to build storage plants — dubbed “Evies” — consisting of a 35-story crane with six arms, surrounded by a tower consisting of thousands of concrete bricks, each weighing about 35 tons.

This plant will “store” energy by using electricity to run the cranes that lift bricks from the ground and stack them atop of the tower, and “discharge” energy by reversing that process. It’s a mechanical twist on the world’s most common energy storage technology, pumped hydro, which “stores” energy by pumping water uphill, and lets it fall to spin turbines when electricity is needed, even as California funds 100-hour long-duration storage pilots to expand flexibility worldwide.

But behind this simplicity lies some heavy-duty software to orchestrate the cranes and blocks, with a "unique stack of proprietary algorithms" to balance energy supply and demand, volatility, grid stability, weather elements and other variables.

CEO and co-founder Robert Piconi said in a November interview with GTM that the standard array would deliver 4 megawatts/35 megawatt-hours of storage, which translates to nearly 9 hours of duration — the equivalent of building the tower to its height, and then reducing it to ground level. It can be built on-site in partnership with crane manufacturers and recycled concrete material, and can run fully automated for decades with little deterioration, he said.

And the cost, which Piconi pegged in the $200 to $250 per kilowatt-hour range, with room to decline further, is roughly 50 percent below the upfront price of the conventional storage market today, and 80 percent below it on levelized cost, he said, a trend utilities see benefits in as they plan resources.

The result, according to Wednesday’s statement, is a technology that could allow “renewables to deliver baseload power for less than the cost of fossil fuels 24 hours a day,” in applications such as community microgrids serving low-income housing.

Wednesday’s announcement builds on a recent investment from Mexico's Cemex Ventures, the corporate venture capital unit of building materials giant Cemex, along with a promise of deployment support from Cemex's strategic network, and also follows project financing for a California green hydrogen microgrid led by the company. Piconi said in November that the company had sufficient investment from two funding rounds to carry it through initial customer deployments, though he declined to disclose figures.

This is the first energy storage investment for Vision Fund, the $100 billion venture fund set up by SoftBank founder Masayoshi Son. While large by startup standards, it’s in keeping with the capital costs that Energy Vault will face in scaling up its technology to meet its commitments, amid mounting demand in regions like Ontario energy storage that face supply crunches. Those include a 35 megawatt-hour order with Tata Power Company, the energy-producing arm of the Indian industrial conglomerate, first unveiled in November, as well as plans to demonstrate its first storage tower in northern Italy in 2019.

For Vision Fund, it’s also an unusual choice for a storage investment, given that the vast majority of venture capital in the industry today is being directed toward lithium-ion batteries, and even Mercedes-Benz energy storage ventures targeting the U.S. market. Lithium-ion batteries are limited in terms of how many hours they can provide cost-effectively, with about 4 hours being seen as the limit today.

The search for long-duration energy storage has driven investment into flow battery technologies such as grid-scale vanadium systems deployed on utility networks, compressed-air energy storage and variations on gravity-based storage, including a previous startup backed by Gross and Idealab, Energy Cache, whose idea of using a ski lift carrying buckets of gravel up a hill to store energy petered out with a 50-kilowatt pilot project.

Wind and solar make more electricity than nuclear for first time in UK

UK Renewables Surpass Nuclear Milestone as wind farms and solar panels outpace atomic output, cutting greenhouse gas emissions. BEIS data show low-carbon power generation rising while onshore wind subsidies and auction timelines face policy debate.

 

Key Points

It is the quarter when UK wind and solar generated more electricity than nuclear, signaling cleaner, low-carbon growth.

✅ BEIS reports wind and solar at 18.33 TWh vs nuclear 16.69 TWh

✅ Energy sector emissions fell 8% as coal use dropped

✅ Calls grow to reopen onshore wind support via CFD auctions

 

Wind farms and solar panels, with wind leading the power mix during key periods, produced more electricity than the UK’s eight nuclear power stations for the first time at the end of last year, official figures show.

Britain’s greenhouse gas emissions also continued to fall, dropping 3% in 2017, as coal use fell and the use of renewables climbed, though low-carbon generation stalled in 2019 according to later data.

Energy experienced the biggest drop in emissions of any UK sector, of 8%, while pollution from transport and businesses stayed flat.

Energy industry chiefs said the figures showed that the government should rethink its ban on onshore wind subsidies, a move that ministers have hinted could happen soon.

Lawrence Slade, chief executive of the big six lobby group Energy UK, said: “We need to keep up the pace ... by ensuring that the lowest cost renewables are no longer excluded from the market.”

Across the whole year, low-carbon sources of power – wind, solar, biomass and nuclear – provided a record 50.4% of electricity, up from 45.7% in 2016, when wind beat coal for the first time.

But in the fourth quarter of 2017, high wind speeds, new renewables installations and lower nuclear output saw wind and solar becoming the second biggest source of power for the first time.

Wind and solar generated 18.33 terawatt hours (TWh), with nuclear on 16.69TWh, and the UK later set a new record for wind power during 2019, the figures published by the Department for Business, Energy and Industrial Strategy show.

But renewables still have a long way to go to catch up with gas, the UK’s top source of electricity at 36.12TWh, which saw its share of generation fall slightly, though at times wind became the main source as capacity expanded.

Greenpeace said the figures showed the government should capitalise on its lead in renewables and “stop wasting time and money propping up nuclear power”.

Horizon Nuclear Power, a subsidiary of the Japanese conglomerate Hitachi, is in talks with Whitehall officials for a financial support package from the government, which it says it needs by midsummer.

By contrast, large-scale solar and onshore wind projects are not eligible for support, after the Conservative government cut subsidies in 2015.

However the energy minister, Claire Perry, recently told House Magazine that “we will have another auction that brings forward wind and solar, we just haven’t yet said when”.

Sask. Party pledges 10% rebate on SaskPower electricity bills

SaskPower 10% Electricity Rebate promises one-year bill relief for households, farms, businesses, hospitals, schools, and universities in Saskatchewan, boosting affordability amid COVID-19, offsetting rate hikes, and countering carbon tax impacts under Scott Moe's plan.

 

Key Points

One-year 10% SaskPower rebate lowering bills for residents, farms, and institutions, funded by general revenue.

✅ Applies automatically to all customers for 12 months from Dec 2020.

✅ Average savings: $215 residential; $845 farm; broad sector coverage.

✅ Cost $261.6M, paid from the general revenue fund; separate from carbon tax.

 

Saskatchewan Party leader Scott Moe says SaskPower customers can expect a one-year, 10 per cent rebate on electricity if they are elected government.

Moe said the pledge aims to make life more affordable for people, including through lower electricity rates initiatives seen in other provinces. The rate would apply to everyone, including residential customers, farmers, businesses, hospitals, schools and universities.

The plan, which would cost government $261.6 million, expects to save the average residential customer $215 over the course of the year and the average farm customer $845.  

“This is a very equitable way to ensure that we are not only providing that opportunity for those dollars to go back into our economy and foster the economic recovery that we are working towards here, in Saskatchewan, across Canada and around the globe, but it also speaks to the affordability for our Saskatchewan families, reducing the dollars a day off to pay for their for their power bill,” Moe said.

The rebate would be applied automatically to all SaskPower bills for 12 months, starting in December 2020. 

Moe said residential customers who are net metering and generating their own power, such as solar power, would receive a $215 rebate over the 12-month period, which is the equivalent of the average residential rebate.

The $261.6 million in costs would be covered by the government’s general revenue fund.   

The Saskatchewan NDP said the proposed reduction is "a big change in direction from the Sask. Party’s long history of making life more expensive for Saskatchewan families." and recently took aim at a SaskPower rate hike approval as part of that critique.

Trent Wotherspoon, NDP candidate for Regina Rosemont and former finance critic, called the pledge criticized the one year time frame and said Saskatchewan people need long term, reliable affordability, noting that the Ontario-Quebec hydro deal has not reduced hydro bills for consumers. Something, he said, is reflected in the NDP plan.

“We've already brought about announcements that bring about affordability, such as the break on SGI auto insurance that'll happen, year after year after year, affordable childcare which has been already announced and committed to things like a decent minimum wage instead of having the lowest minimum wage in Canada,” Wotherspoon said.

The NDP pointed out SaskPower bills have increased by 57 per cent since 2007 for families with an average household income of $75,000, while Nova Scotia's 14% rate hike was recently approved by its regulator.

It said the average bill for such household was $901 in 2007-08 and is now $1,418 in 2019-20, while in neighbouring provinces Manitoba rate increases of 2.5 per cent annually have also been proposed for three years.

"This is on top of the PST increases that the Sask. Party put on everyday families – costing them more than $700 a year," the NDP said.

Moe took aim at the federal Liberal government’s carbon tax, citing concerns that electricity prices could soar under national policies.

He said if the Saskatchewan government wins its court fight against Ottawa, all SaskPower customers can expect to save an additional $150 million per year, and he questioned the federal 2035 net-zero electricity grid target in that context.

“As it stands right now, the Trudeau government plans to raise the carbon tax from $30 to $40 a tonne on Jan. 1,” Moe said. “Trudeau plans to raise taxes and your SaskPower bill, in the middle of a pandemic.  The Saskatchewan Party will give you a break by cutting your power bill.”

Clean B.C. is quietly using coal and gas power from out of province

BC Hydro Electricity Imports shape CleanBC claims as Powerex trades cross-border electricity, blending hydro with coal and gas supplies, affecting emissions, grid carbon intensity, and how electric vehicles and households assess "clean" power.

 

Key Points

Powerex buys power for BC Hydro, mixing hydro with coal and gas, shifting emissions and affecting CleanBC targets.

✅ Powerex trades optimize price, not carbon intensity

✅ Imports can include coal- and gas-fired generation

✅ Emissions affect EV and CleanBC decarbonization claims

 

British Columbians naturally assume they’re using clean power when they fire up holiday lights, juice up a cell phone or plug in a shiny new electric car. 

That’s the message conveyed in advertisements for the CleanBC initiative launched by the NDP government, amid indications that residents are split on going nuclear according to a survey, which has spent $3.17 million on a CleanBC “information campaign,” including almost $570,000 for focus group testing and telephone town halls, according to the B.C. finance ministry.

“We’ll reduce air pollution by shifting to clean B.C. energy,” say the CleanBC ads, which feature scenic photos of hydro reservoirs. “CleanBC: Our Nature. Our Power. Our Future.” 

Yet despite all the bumph, British Columbians have no way of knowing if the electricity they use comes from a coal-fired plant in Alberta or Wyoming, a nuclear plant in Washington, a gas-fired plant in California or a hydro dam in B.C. 

Here’s why. 

BC Hydro’s wholly-owned corporate subsidiary, Powerex Corp., exports B.C. power when prices are high and imports power from other jurisdictions when prices are low. 

In 2018, for instance, B.C. imported more electricity than it exported — not because B.C. has a power shortage (it has a growing surplus due to the recent spate of mill closures and the commissioning of two new generating stations in B.C.) but because Powerex reaps bigger profits when BC Hydro slows down generators to import cheaper power, especially at night.

“B.C. buys its power from outside B.C., which we would argue is not clean,” says Martin Mullany, interim executive director for Clean Energy BC. 

“A good chunk of the electricity we use is imported,” Mullany says. “In reality we are trading for brown power” — meaning power generated from conventional ‘dirty’ sources such as coal and gas. 

Wyoming, which generates almost 90 per cent of its power from coal, was among the 12 U.S. states that exported power to B.C. last year. (Notably, B.C. did not export any electricity to Wyoming in 2018.)

Utah, where coal-fired power plants produce 70 per cent of the state’s energy amid debate over the costs of scrapping coal-fired electricity, and Montana, which derives about 55 per cent of its power from coal, also exported power to B.C. last year. 

So did Nebraska, which gets 63 per cent of its power from coal, 15 per cent from nuclear plants, 14 per cent from wind and three per cent from natural gas.   

Coal is responsible for about 23 per cent of the power generated in Arizona, another exporter to B.C., while gas produces about 44 per cent of the electricity in that state.  

In 2017, the latest year for which statistics are available, electricity imports to B.C. totalled just over 1.2 million tonnes of carbon dioxide emissions, according to the B.C. environment ministry — roughly the equivalent of putting 255,000 new cars on the road, using the U.S. Environmental Protection Agency’s calculation of 4.71 tonnes of annual carbon emissions for a standard passenger vehicle. 

These figures far outstrip the estimated local and upstream emissions from the contested Woodfibre LNG plant in Squamish that is expected to release annual emissions equivalent to 170,000 new cars on the road.

Import emissions cast a new light on B.C.’s latest “milestone” announcement that 30,000 electric cars are now among 3.7 million registered vehicles in the province.

“Making sure more of the vehicles driven in the province are powered by BC Hydro’s clean electricity is one of the most important steps to reduce [carbon] pollution,” said the November 28 release from the energy ministry, noting that electrification has prompted a first call for power in 15 years from BC Hydro.

Mullany points out that Powerex’s priority is to make money for the province and not to reduce emissions.

“It’s not there for the cleanest outcome,” he said. “At some time we have to step up to say it’s either the money or the clean power, which is more important to us?”

Electricity bought and sold by little-known, unregulated Powerex
These transactions are money-makers for Powerex, an opaque entity that is exempt from B.C.’s freedom of information laws. 

Little detailed information is available to the public about the dealings of Powerex, which is overseen by a board of directors comprised of BC Hydro board members and BC Hydro CEO and president Chris O’Reilly. 

According to BC Hydro’s annual service plan, Powerex’s net income ranged from $59 million to $436 million from 2014 to 2018. 

“We will never know the true picture. It’s a black box.” 

Powerex’s CEO Tom Bechard — the highest paid public servant in the province — took home $939,000 in pay and benefits last year, earning $430,000 of his executive compensation through a bonus and holdback based on his individual and company performance.  

“The problem is that all of the trade goes on at Powerex and Powerex is an unregulated entity,” Mullany says. 

“We will never know the true picture. It’s a black box.” 

In 2018, Powerex exported 8.7 million megawatt hours of electricity to the U.S. for a total value of almost $570 million, according to data from the Canada Energy Regulator. That same year, Powerex imported 9.6 million megawatt hours of electricity from the U.S. for almost $360 million. 

Powerex sold B.C.’s publicly subsidized power for an average of $87 per megawatt hour in 2018, according to the Canada Energy Regulator. It imported electricity for an average of $58 per megawatt hour that year. 

In an emailed statement in response to questions from The Narwhal, BC Hydro said “there can be a need to import some power to meet our electricity needs” due to dam reservoir fluctuations during the year and from year to year.

‘Impossible’ to determine if electricity is from coal or wind power
Emissions associated with electricity imports are on average “significantly lower than the emissions of a natural gas generating plant because we mostly import electricity from hydro generation and, increasingly, power produced from wind and solar,” BC Hydro claimed in its statement. 

But U.S. energy economist Robert McCullough says there’s no way to distinguish gas and coal-fired U.S. power exports to B.C. from wind or hydro power, noting that “electrons lack labels.” 

Similarly, when B.C. imports power from Alberta, where generators are shifting to gas and 48.5 per cent of electricity production is coal-fired and 38 per cent comes from natural gas, there’s no way to tell if the electricity is from coal, wind or gas, McCullough says.

“It really is impossible to make that determination.”

Neither the Canada Energy Regulator nor Statistics Canada could provide annual data on electricity imports and exports between B.C. and Alberta. 

But you can watch imports and exports in real time on this handy Alberta website, which also lists Alberta’s power sources. 

In 2018, California, Washington and Oregon supplied considerably more power to B.C. than other states, according to data from Canada Energy Regulator. 

Washington, where about one-quarter of generated power comes from fossil fuels, led the pack, with more than $339 million in electricity exports to B.C. 

California, which still gets more than half of its power from gas-fired plants even though it leads the U.S. in renewable energy with substantial investments in wind, solar and geothermal, was in second place, selling about $18.4 million worth of power to B.C. 

And Oregon, which produces about 43 per cent of its power from natural gas and six per cent from coal, exported about $6.2 million worth of electricity to B.C. last year. 

By comparison, Nebraska’s power exports to B.C. totalled about $1.6 million, Montana’s added up to $1.3 million,  Nevada’s were about $706,000 and Wyoming’s were about $346,000.

Clean electrons or dirty electrons?
Dan Woynillowicz, deputy director of Clean Energy Canada, which co-chaired the B.C. government’s Climate Solutions and Clean Growth Advisory Council, says B.C. typically exports power to other jurisdictions during peak demand. 

Gas-fired plants and hydro power can generate electricity quickly, while coal-fired power plants take longer to ramp up and wind power is variable, Woynillowicz notes. 

“When you need power fast and there aren’t many sources that can supply it you’re willing to pay more for it.”

Woynillowicz says “the odds are high” that B.C. power exports are displacing dirty power.

Elsewhere in Canada, analysts warn that Ontario's electricity could get dirtier as policies change, raising similar concerns.

“As a consumer you never know whether you’re getting a clean electron or a dirty electron. You’re just getting an electron.”
