Hydro-Que9bec 2020 Profit Outlook faces COVID-19 headwinds as revenue drops, U.S. Northeast export demand weakens, and clean-energy infrastructure plans shift toward domestic investments, energy efficiency, EV charging stations, and grid upgrades to stabilize net income.

Key Points

A forecast of COVID-19 revenue declines, weaker U.S. exports, and a shift to energy efficiency and grid upgrades.

✅ Q1 profit fell 14%; net income $1.53B vs $1.77B

✅ Exports to U.S. Northeast weaker; revenue off ~$130M Mar-Jun

✅ Strategy: energy efficiency, EV charging, grid, dam upgrades

Hydro-Québec expects the coronavirus pandemic to chop “hundreds of millions of dollars” off 2020 profits, its new chief executive officer said.

COVID-19 has depressed revenue by about $130 million between March and June, Sophie Brochu said Monday, as residential electricity use rose even while overall consumption dropped. Shrinking electricity exports to the U.S. northeast are poised to compound the shortfall, she said.

“What we’re living through is not small. The impacts are real,” Brochu said on a conference call with reporters, noting that utilities such as Hydro One supported Ontario's COVID-19 response at the height of the pandemic. “I’m not talking about a billion. I’m talking about hundreds of millions. We have no idea how quickly the economy will restart. As we approach the fall we will have a better view.”

Hydro-Québec last month reported a 14-per-cent drop in first-quarter profit and warned full-year results would fall short of targets as the COVID-19 crisis weighs on power demand. Net income in the quarter was $1.53 billion compared with $1.77 billion a year ago, the company said.

Canada’s biggest electricity producer had earlier been targeting 2020 profit of between $2.8 billion and $3 billion, according to its current strategic plan and corporate structure currently in place.

The first quarter was the utility’s last under former CEO Eric Martel, who left to take over at jetmaker Bombardier Inc. Brochu, who previously ran Énergir, replaced him April 6.

To boost exports over time, Brochu said Hydro-Québec will look to strengthen ties with neighbours such as Ontario, where the Hydro One CEO is working to repair relations with government and investors, and the U.S. The CEO said she’s heartened by New York Governor Andrew Cuomo’s call last month for new power lines from Canada and upstate to promote clean energy.

“This is a clear, encouraging signal that must express itself through very concrete negotiations,” she said. “The United States is our backyard. This is true for Ontario, where key system staff lockdowns were even contemplated, and the Atlantic provinces as well. This is our ecosystem, and we intend to build on our footprint, on the relationships that we have.”

Though stricter environmental hurdles make it more complicated to get power lines built today than a decade ago, the CEO insists it’s still possible to sell electricity to neighbouring U.S. states.

“Is it more difficult today to build energy projects? The answer is yes,” she said. “Does this clog up the U.S. northeast market? Not at all. I believe this federation of ecosystems is very promising.”

In the meantime, Hydro-Québec is planning to speed up investments at home — for example, by building new charging stations that will be needed to serve a growing fleet of electric cars. The utility will also upgrade some of its Montreal-area facilities, as well as its massive dams on the Manicouagan River, Brochu said. The investments will result in additional capacity.

“Today we need to put water in the pump of Quebec, so we will concentrate our human and financial efforts here,” she said. “We are needed in Quebec.” 

Hydro-Québec is stepping up efforts to promote energy efficiency among its customer base, amid retroactive billing concerns, which Brochu said could postpone the need to build large dams.

“We have to move towards ‘no-regret moves.’ What’s a no-regret move? It’s energy efficiency,” Brochu said earlier Monday during a presentation to the Chamber of Commerce of Metropolitan Montreal, noting that Ontario debated peak rate relief for self-isolating customers. “This is healthy, it’s fundamental and it will contribute to Quebec’s economic rebound by lowering energy costs.”

Brochu also pledged to build a more diverse workforce after the company said last week that 8.2 per cent of staff belong to “visible and ethnic” minorities.

“This can be improved on,” she said. “What I’m expressing today is my determination, and that of the management team, to move the needle.”

NB Power copper thefts highlight risks at high-voltage substations, with vandalism, fatalities, infrastructure damage, ratepayer costs, and law enforcement alerts tied to metal prices, stolen electricity, and safety concerns across New Brunswick and Nova Scotia.

Key Points

Substation metal thefts causing fatalities, outages, safety risks, and higher costs that impact NB ratepayers.

✅ Spike aligns with copper price near $3 per pound

✅ Fatal break-ins at high-voltage facilities in Bathurst

✅ Repairs, delays, and safety risks for crews, customers

New Brunswick's power utility is urging people to stay away from its substations, saying the valuable copper they contain is proving hard to resist for thieves.

NB Power has seen almost as many incidents of theft and vandalism to its property in April and May of this year, than in all of last year.

In the 2018-2019 fiscal year, the utility recorded 16 cases of theft and/or vandalism.

In April and May, there have already been 13 cases.

One of those was a fatal incident in Bathurst. On April 13, a 41-year-old man was found unresponsive and later died, after breaking into a substation. It was the second fatality linked to a break-in at an NB Power facility in 10 years.

The investigation is still ongoing, but NB Power believes the man was trying to steal copper.

The power utility has been ramping up its efforts -- finding alternate ways to secure its properties, and educate the public -- on the dangers of copper theft, as utilities work to adapt to climate change that can exacerbate severe weather.

“We really, really, really want to stress that if you’re hitting the wrong wire, cutting the wrong wire, breaking in to or cutting fences, a lot of very bad things can happen,” said NB Power spokesperson Marc Belliveau.

In the 2017-2018 fiscal year, there were 24 recorded cases of theft and/or vandalism.

It also comes at a financial cost for NB Power, and ratepayers -- on average, $330,000 a year. About two-thirds of that is copper. The rest is vehicle break-ins or stolen electricity.

“We’ve done analysis,” Belliveau said. “Often the number of break-ins correspond with the price spiking in copper. So, right now, copper’s about $3 a pound. If it was half of that, there might be half as many incidents.”

New Brunswick Public Safety Minister Carl Urquhart says he knows the utility and police are working to dissuade people from the dangers of the theft, and notes that debates around Site C dam stability issues reflect broader infrastructure safety concerns.

“We all know of incident after incident of major injuries and death caused by, simply by, copper,” he said.

Last November, a Dawson Settlement substation was targeted during a major, storm-related power outage in the province.

It meant NB Power had to divert crews to fix and secure the substation, delaying restoration times for some residents and underscoring efforts to improve local reliability across the grid.

Belliveau says that’s “most frustrating.”

“We’re really trying to take a more proactive approach. And certainly, we encourage people that if you know somebody who’s thinking of doing something like that, to really try and talk them out of it because it’s unbelievably dangerous to break in to a substation,” he said.

Nova Scotia Power, connected through the Maritime Link, was not able to provide details on thefts at their substations, but spokesman David Rodenhiser said "the value of the stolen copper is minor in comparison to the risk that’s created when thieves break into our high-voltage electrical substations."

It's not just risky for the people breaking in, and public opposition to projects like Site C underscores broader community safety concerns.

"It also puts the safety of the workers who maintain our substations at risk, because when thieves steal copper, the protective safety devices in the substations don’t work properly," Rodenhiser said.

Additionally, in Nova Scotia, projects like the Maritime Link have advanced regional transmission, and Nova Scotia Power’s copper components have identifying markers, which make that copper difficult to fence. Anyone who buys or sells stolen propery is at risk of criminal charges.

Drax Biomass Conversion accelerates renewable energy by replacing coal with wood pellets, sustainable forestry feedstock, and piloting carbon capture and storage, supporting the UK grid, emissions cuts, and a net-zero pathway.

Key Points

Drax Biomass Conversion is Drax's shift from coal to biomass with CCS pilots to cut emissions and aid UK's net-zero.

✅ Coal units converted to biomass wood pellets

✅ Sourced from sustainable forestry residues

✅ CCS pilots target lifecycle emissions cuts

A power station that used to be the biggest polluter in western Europe has made a near-complete switch to renewable energy, mirroring broader shifts as Denmark's largest energy company plans to end coal by 2023.

The Drax Power Station in Yorkshire, England, used to spew out millions of tons of carbon dioxide a year by burning coal. But over the past eight years, it has overhauled its operations by converting four of its six coal-fired units to biomass. The plant's owners say it now generates 15% of the country's renewable power, as Britain recently went a full week without coal power for the first time.

The change means that just 6% of the utility's power now comes from coal, as the wider UK coal share hits record lows across the national electricity system. The ultimate goal is to stop using coal altogether.

"We've probably reduced our emissions more than any other utility in the world by transforming the way we generate power," Will Gardner, CEO of the Drax Group, told CNN Business.

Subsidies have helped finance the switch to biomass, which consists of plant and agricultural matter and is viewed as a promising substitute for coal, and utilities such as Nova Scotia Power are also increasing biomass use. Last year, Drax received £789 million ($1 billion) in government support.

Is biomass good for the environment?

While scientists disagree over the extent to which biomass as a fuel is environmentally friendly, and some environmentalists urge reducing biomass use amid concerns about lifecycle emissions, Drax highlights that its supplies come from from sustainably managed and growing forests.

Most of the biomass used by Drax consists of low-grade wood, sawmill residue and trees with little commercial value from the United States. The material is compressed into sawdust pellets.

Gardner says that by purchasing bits of wood not used for construction or furniture, Drax makes it more financially viable for forests to be replanted. And planting new trees helps offset biomass emissions.

Forests "absorb carbon as they're growing, once they reach maturity, they stop absorbing carbon," said Raphael Slade, a senior research fellow at Imperial College London.

But John Sterman, a professor at MIT's Sloan School of Management, says that in the short term burning wood pellets adds more carbon to the atmosphere than burning coal.

That carbon can be absorbed by new trees, but Sterman says the process can take decades.

"If you're looking at five years, [biomass is] not very good ... If you're looking at a century-long time scale, which is the sort of time scale that many foresters plan, then [biomass] can be a lot more beneficial," says Slade.

Carbon capture

Enter carbon capture and storage technology, which seeks to prevent CO2 emissions from entering the atmosphere and has been touted as a possible solution to the climate crisis.

Drax, for example, is developing a system to capture the carbon it produces from burning biomass. But that could be 10 years away.

The Coal King is racing to avoid bankruptcy

The power station is currently capturing just 1 metric ton of CO2 emissions per day. Gardner says it hopes to increase this to 10,000 metric tons per day by the mid to late 2020s.

"The technology works but scaling it up and rolling it out, and financing it, are going to be significant challenges," says Slade.

The Intergovernmental Panel on Climate Change shares this view. The group said in a 2018 report that while the potential for CO2 capture and storage was considerable, its importance in the fight against climate change would depend on financial incentives for deployment, and whether the risks of storage could be successfully managed. These include a potential CO2 pipeline break.

In the United Kingdom, the government believes that carbon capture and storage will be crucial to reaching its goal of achieving net-zero greenhouse gas emissions by 2050, even as low-carbon generation stalled in 2019 according to industry analysis.

It has committed to consulting on a market-based industrial carbon capture framework and in June awarded £26 million ($33 million) in funding for nine carbon capture, usage and storage projects, amid record coal-free generation on the British grid.

Great Britain electricity generation spans renewables and baseload: wind, solar, nuclear, gas, and biomass, supported by National Grid interconnectors, embedded energy estimates, and BMRS data for dynamic imports and exports across Europe.

Key Points

A diverse, weather-driven mix of renewables, gas, nuclear, and imports coordinated by National Grid.

✅ Baseload from nuclear and biomass; intermittent wind and solar

✅ Interconnectors trade zero carbon imports via subsea cables

✅ Data from BMRS and ESO covers embedded energy estimates

Great Britain has one of the most diverse ranges of electricity generation in Europe, with everything from windfarms off the coast of Scotland to a nuclear power station in Suffolk tasked with keeping the lights on. The increasing reliance on renewable energy sources, as part of the country’s green ambitions, also means there can be rapid shifts in the main source of electricity generation. On windy days, most electricity generation comes from record wind generation across onshore and offshore windfarms. When conditions are cold and still, gas-fired power stations known as peaking plants are called into action.

The electricity system in Great Britain relies on a combination of “baseload” power – from stable generators such as nuclear and biomass plants – and “intermittent” sources, such as wind and solar farms that need the right weather conditions to feed energy into the grid. National Grid also imports energy from overseas, through subsea cables known as interconnectors that link to France, Belgium, Norway and the Netherlands. They allow companies to trade excess power, such as renewable energy created by the sun, wind and water, between different countries. By 2030 it is hoped that 90% of the energy imported by interconnectors will be from zero carbon energy sources, though low-carbon electricity generation stalled in 2019 for the UK.

The technology behind Great Britain’s power generation has evolved significantly over the last century, and at times wind has been the main source of electricity. The first integrated national grid in the world was formed in 1935 linking seven regions of the UK. In the aftermath of industrialisation, coal provided the vast majority of power, before oil began to play an increasingly important part in the 1950s. In 1956, the world’s first commercial nuclear reactor, Calder Hall 1 at Windscale (later Sellafield), was opened by Queen Elizabeth II. Coal use fell significantly in the 1990s while the use of combined cycle gas turbines grew, and in 2016 wind generated more electricity than coal for the first time. Now a combination of gas, wind, nuclear and biomass provide the bulk of Great Britain’s energy, with smaller sources such as solar and hydroelectric power also used. From October 2024, coal will no longer be used to generate electricity, following coal-free power records set in recent years.

Energy generation data is fetched from the Balancing Mechanism Reporting Service public feed, provided by Elexon – which runs the wholesale energy market – and is updated every five minutes, covering periods when wind led the power mix as well.

Elexon’s data does not include embedded energy, which is unmetered and therefore invisible to Great Britain’s National Grid. Embedded energy comprises all solar energy and wind energy generated from non-metered turbines. To account for these figures we use embedded energy estimates from the National Grid electricity system operator, which are published every 30 minutes.

Import figures refer to the net flow of electricity from the interconnectors with Europe and with Northern Ireland. A positive value represents import into the GB transmission system, while a negative value represents an export.

Hydro figures combine renewable run-of-the-river hydropower and pumped storage.

Biomass figures include Elexon’s “other” category, which comprises coal-to-biomass conversions and biomass combined heat and power plants.

Wylfa Nuclear Project Cancellation reflects Hitachi's withdrawal, pulling £16bn from North Wales, risking jobs, reshaping UK nuclear power plans as renewables grow and Chinese involvement rises amid shifting energy market policies.

Key Points

An indefinite halt to Hitachi's Wylfa Newydd nuclear plant, removing about £16bn investment and jobs from North Wales.

✅ Hitachi withdraws funding amid changing energy market costs

✅ Puts 400 local roles and up to 10,000 construction jobs at risk

✅ UK shifts toward renewables as nuclear project support stalls

Chris Ruane said Japanese firm Hitachi’s announcement this morning about the Wylfa project would take £16 billion of investment out of the region.

He said it was the latest in a list of energy projects which had been scrapped as he responded to a statement from business secretary Greg Clark.

Mr Ruane, the Labour member for the Vale of Clywd, said: “In his statement he said the Government are relying now more on renewables, can I put the North Wales picture to him; 1,500 wind turbines were planned off the coast of North Wales. They were removed, those plans were cancelled by the private sector.

“The tidal lagoons for Wales were key to the development of the Welsh economy – the Government itself pulled the support for the Swansea Bay tidal lagoon. That had a knock-on effect for the huge lagoon planned off the coast of North Wales.

“And now today we hear of the cancellation of a £16 billion investment in the North Wales economy. This will devastate the North Wales economy. The people of North Wales need to know that the Prime Minister is batting for them and batting for the UK.”

Mr Clark blamed the changing landscape of the energy market for today’s announcement, and said Wales has been a “substantial and proud leader” in renewable energy during the UK’s green industrial revolution over recent years.

But another Labour MP from North Wales, Albert Owen, of Ynys Mon, said the Wylfa plant’s cancellation in his constituency is putting 400 jobs at risk, as well as the “potential of 8-10,000 construction jobs”, as well as hundreds of operational jobs and 33 apprenticeships.

He asked Mr Clark: “Can I say straightly can we work together to keep this project alive, to ensure that we create the momentum so it can be ready for a future developer or this developer with the right mechanism?”

The minister replied that he and his officials would “work together in a completely open-book way on the options” to try and salvage the project.

But in the Lords, Labour former security minister Lord West of Spithead said the UK’s nuclear industry was in crisis, noting that Europe is losing nuclear power as well.

“In the 1950s our nation led the world in nuclear power generation and decisions by successive governments, of all hues, have got us in the position today where we cannot even construct a large civil nuclear reaction,” he told peers at question time.

Lord West asked: “Are we content that now the only player seems to be Chinese and that by 2035… we are happy for the Chinese to control one third of the energy supply of our nation?”

Business, Energy and Industrial Strategy minister Lord Henley said the Government had hoped for a better announcement from Hitachi but that was not the case.

He said costs in the nuclear sector were rising, amid setbacks at Hinkley Point C, while costs for many renewables were coming down and this was one of the reasons for the problem.

Tory former energy secretary Lord Howell of Guildford said the Chinese were in “pole position” for the rebuilding and replacement “of our nuclear fleet” and this would have a major impact on UK energy policy and plans to meet net zero targets in the 2030s.

Plaid Cymru’s Lord Wigley warned that putting the Wylfa Newydd on indefinite hold would cause economic planning blight in north-west Wales and urged the Government to raise the level of support allocated to the region.

Lord Henley acknowledged the announcement was not welcome but added: “We remain committed to nuclear power. We will look to see what we can do. We still have a great deal of expertise in this country and we can work on that.”
