Ontario residents are learning to live better with less electricity, says a recent report.

Consumption is dropping faster than at any previous time and the province is ahead of the conservation target it set three years ago, Peter Love, chief energy conservation officer with the Ontario Power Authority, said in an interview.

"We're getting there, but there's a long way to go," he said.

From 2005 to 2007, Ontario's total consumption fell by 2.6 per cent to 150,8906 gigawatt hours, and the average for each person dropped by 4.6 per cent to 11,725 kilowatt hours. Both figures are adjusted for changes in the weather.

In addition, last year's weather-adjusted peak demand – the highest recorded use of electricity, a hot day when air conditioners were cranked up – was 24,820 megawatts, which was 1,462 megawatts below the amount forecast a couple of years ago by the Independent Electricity System Operator, the provincial agency that controls the flow of electricity.

That beat Queen's Park's first-stage goal – a reduction of 1,350 megawatts – for the first three years of its plan to cut peak demand by 6,300 megawatts by 2025.

"We have a lot of work to do. We're looking to create a culture of conservation. It happens over decades," Love said.

The decline shows the Liberal government should rethink its focus on building new nuclear power plants, said Chris Winter, head of the Conservation Council of Ontario, an independent advocacy group.

Critics have said the government is moving far too slowly on conservation as it plans $40 billion worth of new nuclear generating stations.

The report "tells me that people are getting the message and that those of us who said we could go much faster were right, " Winter said. "We always said they could achieve 6,300 megawatts (of reduction) by 2012. At what point do they get the message that people prefer conservation to coal, nuclear or other dirty power?"

But Love said Ontario's conservation goal is far tougher than others in North America. "The next target will be much more difficult."

The power authority has launched 26 conservation programs, ranging from an incentive to encourage homeowners to get rid of energy-sucking old beer fridges to technical help for major industries.

No new residential incentives are planned for this summer, but the province has installed 1.4 million "smart meters," out of 4.3 million in total, that will reward consumers for using appliances during periods of low demand.

When it's finally underway, the charge for electricity – now no more than 5.9 cents per kilowatt hour – will be 9.3 cents during peak times, 7.3 cents in medium periods and only 2.7 cents in off-peak times, generally overnight. A kilowatt-hour is the amount of electricity required to keep a 100-watt light burning for 10 hours, and one billion kilowatts equals one gigawatt.

The conservation effort is a far cry from the 1960s, when the former Ontario Hydro exhorted consumers to turn up their thermostats, take off their socks and "live better electrically." It's also different from the province's only previous attempt to curb demand, when, from 1988 to '92, Hydro had a team of more than 500 staff pushing the conservation message. That program resulted in about half the total electricity savings of the current effort, the power authority says.

The authority is contracting out much of the current conservation work to utilities, energy service companies and non-profit groups.

Ontario's electricity rates are still much lower than most other parts of the world, Paul Shervill, the power authority's vice-president of conservation development said.

Electrifying Manitoba: How hydro power 'absolutely revolutionized' the province

Manitoba Electrification History charts arc lights, hydroelectric dams, Winnipeg utilities, transmission lines, rural electrification, and Manitoba Hydro to today's wind, solar, and EV transition across the provincial power grid, driving modernization and reliability.

 

Key Points

Manitoba's power evolution from arc lights to hydro and rural electrification, advancing wind and solar on a modern grid.

✅ 1873 Winnipeg arc light predates Edison and Bell.

✅ 1919 Act built transmission lines, rural electrification.

✅ Hydroelectric dams reshaped lands and affected First Nations.

 

The first electric light in Manitoba was turned on in Winnipeg in 1873, but it was a century ago this year that the switch was flipped on a decision that would bring power to the fingertips of people across the province.

On March 12, 1873, Robert Davis — who owned the Davis House hotel on Main Street, about a block from Portage Avenue — used an electric arc light to illuminate the front of his building, according to A History of Electric Power in Manitoba, published by Manitoba Hydro.

That type of light used an an inert gas in a glass container to create an electric arc between two metal electrodes.

"The lamp in front of the Davis Hotel is quite an institution," a Manitoba Free Press report from the day said. "It looks well and guides the weary traveller to a haven of rest, billiards and hot drinks."

The event took place six years before Thomas Edison's first incandescent lamp was invented and three years before the first complete sentence was spoken over the telephone by Alexander Graham Bell.

"Electrification probably had a bigger influence on the lives of Manitobans than virtually anything else," said Gordon Goldsborough, head researcher with the Manitoba Historical Society.

"It's one of the most significant changes in the lives of Manitobans ever, because basically it transformed so many aspects of their lives. It wasn't just one thing — it touched pretty much every aspect of life."

 

Winnipeg gets its 1st street lamps

In the pioneer days of lighting and street railway transportation in Winnipeg, multiple companies formed in an effort to take advantage of the new utility: Winnipeg Gas Company, Winnipeg General Power Company, Manitoba Electric and Gas Light Company, and The North West Electric Light and Power Company.

In October 1882, the first four street lamps, using electric arc lights, were turned on along Main Street from Broadway to the CPR crossing over the Assiniboine River.

They were installed privately by P.V. Carroll, who came from New York to establish the Manitoba Electric Light & Power Company and try to win a contract for illuminating the rest of the city's streets.

He didn't get it. Newspaper reports from the time noted many outages and other problems and general disappointment in the quality of the light.

Instead, the North West Electric Light and Power Company won that contract and in June 1883 it lit up the streets.

Over the years, other companies would bring power to the city as it became more reliable, including the Winnipeg Electric Street Railway Company (WERCo), which built the streetcar system and sold electric heat, light and power.

But it was the Brandon Electric Light Company that first tapped into a new source of power — hydro. In 1900, a dam was built across the Minnedosa River (now known as the Little Saskatchewan River) in western Manitoba, and the province's first hydroelectric generating station was created.

The first transmission line was also built, connecting the station with Brandon.

By 1906, WERCo had taken over the Winnipeg General Power Company and the Manitoba Electric and Gas Light Company, and changed its name to the Winnipeg Electric Railway Company. Later, it became the Winnipeg Electric Company, or WECo.

It also took a cue from Brandon, building a hydroelectric plant to provide more power. The Pinawa dam site operated until 1951 and is now a provincial park.

The City of Winnipeg Hydroelectric System was also formed in 1906 as a public utility to combat the growing power monopoly held by WECo, and to get cheaper power. The city had been buying its supply from the private company "and the City of Winnipeg didn't quite like that price," said Bruce Owen, spokesman for Manitoba Hydro.

So the city funded and built its own dam and generating station site on the Winnipeg River in Pointe du Bois — about 125 kilometres northeast of Winnipeg — which is still in operation today.

"All of a sudden, not only did we have street lights … businesses had lights, power was supplied to homes, people no longer had to cook on wood stoves or walk around with kerosene lanterns. This city took off," said Owen.

"It helped industry grow in the city of Winnipeg. Within a few short years, a second plant had to be built, at Slave Falls."

 

Lighting up rural Manitoba

While the province's two biggest cities enjoyed the luxury of electricity and the conveniences it brought, the patchwork of power suppliers had also created a jumble of contracts with differing rates and terms, spurring periodic calls for a western Canadian electricity grid to improve coordination.

Meanwhile, most of rural Manitoba remained in the dark.

That began to change in 1919 when the Manitoba government passed the Electric Power Transmission Act, with the aim of supplying rural Manitoba with electrical power. The act enabled the construction of transmission lines to carry electricity from the Winnipeg River generating stations to communities all over southern Manitoba.

It also created the Manitoba Power Commission, predecessor to today's Manitoba Hydro, to purchase power from the City of Winnipeg — and later WECo — to supply to those other communities.

The first transmission line, a 97-kilometre link between Winnipeg and Portage la Prairie, opened in late 1919, and modern interprovincial projects like Manitoba-Saskatchewan power line funding continue that legacy today. The power came from Pointe du Bois to a Winnipeg converter station that still stands at the corner of Stafford Street and Scotland Avenue, then went on to Portage la Prairie.

"That's the remarkable thing that started in 1919," said Goldsborough.

Every year after that, the list of towns connected to the power grid became longer "and gradually, over the early 20th century, the province became electrified," Goldsborough said.

"You'd see these maps that would spider out across the province showing the [lines] that connected each of these communities — a precursor to ideas like macrogrids — to each other, and it was really quite remarkable."

By 1928, 33 towns were connected to the Manitoba Power Commission grid. That rose to 44 by 1930 and 140 by 1939, according to the Manitoba Historical Society.

 

Power on the farm

Still, one group who could greatly use electricity for their operations — farmers — were still using lanterns, steam and coal for light, heat and power.

"The power that came to the [nearest] town didn't extend to them," said Goldsborough.

It was during the Second World War, as manual labour was hard to come by on farms, that the Manitoba Power Commission recognized the gap in its grid.

It met with farmers to explain the benefits electricity could bring and surveyed their interest. When the war ended in 1945, the farm electrification process got underway.

Farmers were taught wiring techniques and about the use of motors for farm equipment, as well as about electric appliances and other devices to ease the burden of domestic life.

"The electrification of the 1940s and '50s absolutely revolutionized rural life," said Goldsborough.

"Farmers had to provide water for all those animals and in a lot of cases [prior to electrification] they would just use a hand pump, or sometimes they'd have a windmill. But these were devices that weren't especially reliable and they weren't high capacity."

Electric motors changed everything, from pumping water to handling grain, while electric heat provided comfort to both people and animals.

"Now you could have heat lamps for your baby chickens. They would lose a lot of chickens normally, because they would simply be too cold," Goldsborough said.

Keeping things warm was important, but so too was refrigeration. In addition to being able to store meat in summer, it was "something to prolong the life of dairy products, eggs, anything," said Manitoba Hydro's Owen.

"It's all the things we take for granted — a flick of a switch to turn the lights on instead of walking around with a lantern, being able to have maybe a bit longer day to do routine work because you have light."

Agriculture was the backbone of the province but it was limited without electricity, said Owen.

Connecting it to the grid "brought it into the modern age and truly kick-started it to make it a viable part of our economy," he said. "And we still see that today."

In 1954, when the farm electrification program ended, Manitoba was the most wired of the western provinces, with 75 per cent of farms and 100,000 customers connected.

The success of the farm electrification program, combined with the post-war boom, brought new challenges, as the existing power generation could not support the new demand.

The three largest players — City Hydro, WECo and the Manitoba Power Commission, along with the provincial government  — created the Manitoba Hydro-Electric Board in 1949 to co-ordinate generation and distribution of power.

More hydroelectric generating stations were built and more reorganizations took place. WECo was absorbed by the board and its assets split into separate companies — Greater Winnipeg Gas and Greater Winnipeg Transit.

Its electricity distribution properties were sold to City Hydro, which became the sole distributor in central Winnipeg. The Manitoba Power Commission became sole distributor of electricity in the suburbs and the rest of Manitoba.

 

Impacts on First Nations

Even as the lives of many people in the province were made easier by the supply of electricity, many others suffered from negative impacts in the rush of progress.

Many First Nations were displaced by hydro dams, which flooded their ancestral lands and destroyed their traditional ways of life.

"And we hear stories about the potential abuses that occurred," said Goldsborough. "So you know, there are there pluses but there are definitely minuses."

In the late 1950s, the Manitoba Power Commission continued to grow and expand its reach, this time moving into the north by buying up private utilities in The Pas and Cranberry Portage.

In 1961, the provincial government merged the commission with the Manitoba Hydro-Electric Board to create Manitoba Hydro.

In 1973, 100 years after the first light went on at that Main Street hotel, the last of the independent power utilities in the province — the Northern Manitoba Power Company Ltd. — was taken over by Hydro.

Winnipeg Hydro, previously called City Hydro, joined the fold in 2002.

Today, Manitoba Hydro operates 15 generating stations and serves 580,262 electric power customers in the province, as well as 281,990 natural gas customers.

 

New era

And now, as happened in 1919, a new era in electricity distribution is emerging as alternative sources of power — wind and solar — grow in popularity, and as communities like Fort Frances explore integrated microgrids for resilience.

"There's a bit of a clean energy shift happening," said Owen, adding use of biomass energy — energy production from plant or animal material — is also expanding.

"And there's a technological change going on and that's the electrification of vehicles. There are only really several hundred [electric vehicles] in Manitoba on the streets right now. But we know at some point, with affordability and reliability, there'll be a switch over and the gas-powered internal combustion engine will start to disappear."

'We're just a little behind here': Manitoba electric vehicle owners call for more charging stations

That means electrical utilities around the world are re-examining their capabilities, as climate change increasingly stresses grids, said Owen.

"It's coming [and we need to know], are we in a position to meet it? What will be the demands on the system on a path to a net-zero grid by 2050 nationwide?" he said.

"It may not come in my lifetime, but it is coming."

Germany shuts down its last three nuclear power plants

Germany Nuclear Phase-Out ends power generation from reactors, prioritizing energy security, renewables, and emissions goals amid the Ukraine war, natural gas shortages, decommissioning plans, and climate change debates across Europe and the national power grid.

 

Key Points

Germany Nuclear Phase-Out ends reactors, shifting to renewables to balance energy security, emissions, climate goals.

✅ Three reactors closed: Emsland, Isar II, Neckarwestheim II

✅ Pivot to renewables, efficiency, and grid resilience

✅ Continued roles in fuel fabrication and decommissioning

 

Germany is no longer producing any electricity from nuclear power plants, a move widely seen as turning its back on nuclear for good.

Closures of the Emsland, Isar II, and Neckarwestheim II nuclear plants in Germany were expected. The country announced plans to phase out nuclear power in 2011. However, in the fall of 2022, with the Ukraine war constraining access to energy, especially in Europe, Germany decided to extend nuclear power operations for an additional few months to bolster supplies.

“This was a highly anticipated action. The German government extended the lifetimes of these plants for a few months but never planned beyond that,” David Victor, a professor of innovation and public policy at UC San Diego, said.

Responses to the closures ranged from aghast that Germany would shut down a clean source of energy production, especially as Europe is losing nuclear power just when it really needs energy. In contrast, the global response to anthropogenic climate change continues to be insufficient to celebratory that the country will avoid any nuclear accidents like those that have happened in other parts of the world.

A collection of esteemed scientists, including two Nobel laureates and professors from MIT and Columbia, made a last-minute plea in an open letter published on April 14 on the nuclear advocacy group’s website, RePlaneteers, to keep the reactors operating, reviving questions about a resurgence of nuclear energy in Germany today.

“Given the threat that climate change poses to life on our planet and the obvious energy crisis in which Germany and Europe find themselves due to the unavailability of Russian natural gas, we call on you to continue operating the last remaining German nuclear power plants,” the letter states.

The open letter states that the Emsland, Isar II, and Neckarwestheim II facilities provided more than 10 million German households with electricity, even as some officials argued that nuclear would do little to solve the gas issue then. That’s a quarter of the population.

“This is hugely disappointing, when a secure low carbon 24/7 source of energy such as nuclear was available and could have continued operation for another 40 years,” Henry Preston, spokesperson for the World Nuclear Association. “Germany’s nuclear industry has been world-class. All three reactors shut down at the weekend performed extremely well.”

Despite the shutdown, some segments of nuclear industrial processes will continue to operate. “Germany’s nuclear sector will continue to be first class in the wider nuclear supply chain in areas such as fuel fabrication and decommissioning,” Preston said.

While the open letter did not succeed in keeping the nuclear reactors open, it does underscore a crucial reason why nuclear power has been part of global energy conversations recently, with some arguing it is a needed option for climate policy after a generational lull in the construction of nuclear power plants: climate change.

Generating electricity with nuclear reactors does not create any greenhouse gases. And as global climate change response efforts continue to fall short of emission targets, atomic energy is getting renewed consideration, and Germany has even considered a U-turn on its phaseout amid renewed debate.

IAEA - COVID-19 and Low Carbon Electricity Lessons for the Future

Nuclear Power Resilience During COVID-19 shows low-carbon electricity supporting renewables integration with grid flexibility, reliability, and inertia, sustaining decarbonization, stable baseload, and system security while prices fell and demand dropped across markets.

 

Key Points

It shows nuclear plants providing reliable, low-carbon power and supporting grid stability despite demand declines.

✅ Low prices challenge investment; lifetime extensions are cost-effective.

✅ Nuclear provides inertia, reliability, and dispatchable capacity.

✅ Market reforms should reward flexibility and grid services.

 

The COVID-19 pandemic has transformed the operation of power systems across the globe, including European responses that many argue accelerated the transition, and offered a glimpse of a future electricity mix dominated by low carbon sources.

The performance of nuclear power, in particular, demonstrates how it can support the transition to a resilient, clean energy system well beyond the COVID-19 recovery phase, and its role in net-zero pathways is increasingly highlighted by analysts today.

Restrictions on economic and social activity during the COVID-19 outbreak have led to an unprecedented and sustained decline in demand for electricity in many countries, in the order of 10% or more relative to 2019 levels over a period of a few months, thereby creating challenging conditions for both electricity generators and system operators (Fig. 1). The recent Sustainable Recovery Report by the International Energy Agency (IEA) projects a 5% reduction in global electricity usage for the entire year 2020, with a record 5.7% decline foreseen in the United States alone. The sustainable economic recovery will be discussed at today's IEA Clean Energy Transitions Summit, where Fatih Birol's call to keep options open will be prominent as IAEA Director General Rafael Mariano Grossi participates.

Electricity generation from fossil fuels has been hard hit, due to relatively high operating costs compared to nuclear power and renewables, as well as simple price-setting mechanisms on electricity markets. By contrast, low-carbon electricity prevailed during these extraordinary circumstances, with the contribution of renewable electricity rising in a number of countries as analyses see renewables eclipsing coal by 2025, due to an obligation on transmission system operators to schedule and dispatch renewable electricity ahead of other generators, as well as due to favourable weather conditions.

Nuclear power generation also proved to be resilient, reliable and adaptable. The nuclear industry rapidly implemented special measures to cope with the pandemic, avoiding the need to shut down plants due to the effects of COVID-19 on the workforce or supply chains. Nuclear generators also swiftly adapted to the changed market conditions. For example, EDF Energy was able to respond to the need of the UK grid operator by curtailing sporadically the generation of its Sizewell B reactor and maintain a cost-efficient and secure electricity service for consumers.

Despite the nuclear industry's performance during the pandemic, faced with significant decreases in demand, many generators have still needed to reduce their overall output appreciably, for example in France, Sweden, Ukraine, the UK and to a lesser extent Germany (Fig. 2), even as the nuclear decline debate continues in Europe. Declining demand in France up to the end of March already contributed to a 1% drop in first quarter revenues at EDF, with nuclear output more than 9% lower than in the year before. Similarly, Russia's Rosatom experienced a significant demand contraction in April and May, contributing to an 11% decline in revenues for the first five months of the year.

Overall, the competitiveness and resilience of low carbon technologies have resulted in higher market shares for nuclear, solar and wind power in many countries since the start of lockdowns (Fig. 3), and low-emissions sources to meet demand growth over the next three years. The share of nuclear generation in South Korea rose by almost 9 percentage points during the pandemic, while in the UK, nuclear played a big part in almost eliminating coal generation for a period of two months. For the whole of 2020, the US Energy Information Administration's Short-Term Energy Outlook sees the share of nuclear generation increasing by more than one percentage point compared to 2019. In China, power production decreased during January-February 2020 by more than 8% year on year: coal power decreased by nearly 9%, hydropower by nearly 12%. Nuclear has proved more resilient with a 2% reduction only. The benefits of these higher shares of clean energy in terms of reduced emissions of greenhouse gases and other air pollutants have been on full display worldwide over the past months.

Challenges for the future

Despite the demonstrated performance of a cleaner energy system through the crisis - including the capacity of existing nuclear power plants to deliver a competitive, reliable, and low carbon electricity service when needed - both short- and long-term challenges remain.

In the shorter term, the collapse in electricity demand has accelerated recent falls in electricity prices, particularly in Europe (Fig. 4), from already economically unsustainable levels. According to Standard and Poor's Midyear Update, the large price drops in Europe result from not only COVID-19 lockdown measures but also collapsing demand due to an unusually warm winter, increased supply from renewables in a context of lower gas prices and CO2 allowances . Such low prices further exacerbate the challenging environment faced by many electricity generators, including nuclear plants. These may impede the required investments in the clean energy transition, with longer term consequences on the achievement of climate goals.

For nuclear power, maintaining and extending the operation of existing plants is essential to support and accelerate the transition to low carbon energy systems. With a supportive investment environment, a 10-20 year lifetime extension can be realized at an average cost of US $30-40/MW*h, making it among the most cost-effective low-carbon options, while also maintaining dispatchable capacity and lowering the overall cost of the clean energy transition. The IEA Sustainable Recovery report indicates that without such extensions 40% of the nuclear fleet in developed economies may be retired within a decade, adding around US$ 80 billion per year to electricity bills. The IEA note the potential for nuclear plant maintenance and extension programmes to support recovery measures by generating significant economic activity and employment.

The need for flexibility

New nuclear power projects can provide similar economic and environmental benefits and applications beyond electricity, but will be all the more challenging to finance without strong policy support and more substantive power market reforms, including improved frameworks for remunerating reliability, flexibility and other services. The need for flexibility in electricity generation and system operation - a trend accelerated by the crisis - will increasingly characterize future energy systems over the medium to longer term.

Looking further ahead, while generators and system operators successfully responded to the crisis, the observed decline in fossil fuel generation draws attention to additional grid stability challenges likely to emerge further into the energy transition. Heavy rotating steam and gas turbines provide mechanical inertia to an electricity system, thereby maintaining its balance. Replacing these capacities with variable renewables may result in greater instability, poorer power quality and increased incidence of blackouts. Large nuclear power plants along with other technologies can fill this role, alleviating the risk of supply disruptions in fully decarbonized electricity systems.

The challenges created by COVID-19 have also brought into focus the need to ensure resilience is built-in to future energy systems to cope with a broader range of external shocks, including more variable and extreme weather patterns expected from climate change.

The performance of nuclear power during the crisis provides a timely reminder of its ongoing contribution and future potential in creating a more sustainable, reliable, low carbon energy system.

Growing pot sucks up electricity and pumps out an astounding amount of carbon dioxide — it doesn't have to

Sustainable Cannabis Cultivation leverages greenhouse design, renewable energy, automation, and water recapture to cut electricity use, emissions, and pesticides, delivering premium yields with natural light, smart sensors, and efficient HVAC and irrigation control.

 

Key Points

A data-driven, low-impact method that cuts energy, water, and chemicals while preserving premium yields.

✅ 70-90% less electricity vs. conventional indoor grows

✅ Natural light, solar, and rainwater recapture reduce footprint

✅ Automation, sensors, and HVAC stabilize microclimates

 

In the seven months since the Trudeau government legalized recreational marijuana use, licensed producers across the country have been locked in a frenetic race to grow mass quantities of cannabis for the new market.

But amid the rush for scale, questions of sustainability have often taken a back seat, and in Canada, solar adoption has lagged in key sectors.

According to EQ Research LLC, a U.S.-based clean-energy consulting firm, cannabis facilities can need up to 150 kilowatt-hours of electricity per year per square foot. Such input is on par with data centres, which are themselves 50 to 200 times more energy-intensive than a typical office building, and achieving zero-emission electricity by 2035 would help mitigate the associated footprint.

At the Lawrence Berkley National Laboratory in California, a senior scientist estimated that one per cent of U.S. electricity use came from grow ops. The same research — published in 2012 — also found that the procedures for refining a kilogram of weed emit around 4,600 kilograms of carbon dioxide to the atmosphere, equivalent to operating three million cars for a year, though a shift to zero-emissions electricity by 2035 could substantially cut those emissions.

“All factors considered, a very large expenditure of energy and consequent ‘environmental imprint’ is associated with the indoor cultivation of marijuana,” wrote Ernie Small, a principal research scientist for Agriculture and Agri-Food Canada, in the 2018 edition of the Biodiversity Journal.

Those issues have left some turning to technology to try to reduce the industry’s footprint — and the economic costs that come with it — even as more energy sources make better projects for forward-looking developers.

“The core drawback of most greenhouse environments is that you’re just getting large rooms, which are harder to control,” says Dan Sutton, the chief executive officer of Tantalus Labs., a B.C.-based cannabis producer. “What we did was build a system specifically for cannabis.”

Sutton is referring to SunLab, the culmination of four years of construction, and at present the main site where his company nurtures rows of the flowering plant. The 120,000-square foot structure was engineered for one purpose: to prove the merits of a sustainable approach.

“We’re actually taking time-series data on 30 different environmental parameters — really simple ones like temperature and humidity — all the way down to pH of the soil and water flow,” says Sutton. “So if the temperature gets a little too cold, the system recognizes that and kicks on heaters, and if the system senses that the environment is too hot in the summertime, then it automatically vents.”

A lot is achieved without requiring much human intervention, he adds. Unlike conventional indoor operations, SunLab demands up to 90 per cent less electricity, avoids using pesticides, and draws from natural light and recaptured rainwater to feed its crops.

The liquid passes through a triple-filtration process before it is pumped into drip irrigation tubing. “That allows us to deliver a purity of water input that is cleaner than bottled water,” says Sutton.

As transpiration occurs, a state-of-the-art, high-capacity airflow suspended below the ceiling cycles air at seven-minute intervals, repeatedly cooling the air and preventing outbreaks of mould, while genetically modified “guardian” insects swoop in to eliminate predatory pests.

“When we first started, people never believed we would cultivate premium quality cannabis or cannabis that belongs on the top shelf, shoulder to shoulder with the best in the world and the best of indoor,” says Sutton.

Challenges still exist, but they pale in comparison to the obstacles that American companies with an interest in adopting greener solutions persistently face, and in provinces like Alberta, an Alberta renewable energy surge is reshaping the opportunity set.

Although cannabis is legal in a number of states, it remains illegal federally, which means access to capital and regulatory clarity south of the border can be difficult to come by.

“Right now getting a new project built is expensive to do because you can’t get traditional bank loans,” says Canndescent CEO Adrian Sedlin, speaking by phone from California.

In retrofitting the company’s farm to accommodate a sizeable solar field, he struggled to secure investors, even as a solar-powered cannabis facility in Edmonton showcased similar potential.

“We spent over a year and a half trying to get it financed,” says Sedlin. “Finding someone was the hard part.”

Decriminalizing the drug would ultimately increase the supply of capital and lower the costs for innovative designs, something Sedlin says would help incentivize producers to switch to more effective and ecologically sound techniques.

Some analysts argue that selling renewable energy in Alberta could become a major growth avenue that benefits energy-intensive industries like cannabis cultivation.

Canndescent, however, is already there.

“We’re now harnessing the sun to reduce our reliance on fossil fuels and going to sustainable, or replenishable, energy sources, while leveraging the best and most efficient water practices,” says Sedlin. “It’s the right thing to do.”

The federal government is investing $16.5 million in Yukon Energy’s construction of a new battery storage system in Yukon. Once completed, the 8 MW battery will be the largest grid-connected battery in the North, and one of the largest in Canada, alongside major Ontario battery projects underway.

The new battery is a critical investment in Yukon Energy’s ability to meet growing demands for power and securing Yukon’s energy future. As an isolated grid, one of the largest challenges Yukon Energy faces is meeting peak demands for power during winter months, as electrification grows with EV adoption in the N.W.T. and beyond.

When complete, the new system will store excess electricity generated during off-peak periods, complementing emerging vehicle-to-grid integration approaches, and provide Yukoners with access to more power during peak periods. This new energy storage system will create a more reliable power supply and help reduce the territory’s reliance on diesel fuel. Over the 20-year life of project, the new battery is expected to reduce carbon emissions in Yukon by more than 20,000 tonnes.

A location for the new battery energy storage system has not been identified. Yukon Energy will begin permitting of the project in 2020 with construction targeted to be complete by mid-2023.

 

Project 2: Replacing and upgrading the Mayo to McQuesten Transmission Line

Yukon Energy has received $22.7 million in federal funding to proceed with Stage 1 of the Stewart to Keno City Transmission Project – replacing and upgrading the 65 year-old transmission line between Mayo and McQuesten. The project also includes the addition of system protection equipment at the Stewart Crossing South substation. The Yukon government, through the Yukon Development Corporation, has already provided $3.5 million towards planning for the project.

Replacing the Mayo to McQuesten transmission line is critical to Yukon Energy’s ability to deliver safe and reliable electricity to customers in the Mayo and Keno regions, mirroring broader regional transmission initiatives that enhance grid resilience, and to support economic growth in Yukon. The transmission line has reached end-of-life and become increasingly unreliable for customers in the area.

The First Nation of Na-Cho Nyak Dun has expressed their support of this project. The project has also been approved by the Yukon Environmental and Socio-Economic Assessment Board.

Yukon Energy will begin replacing and upgrading the 31 km transmission line between Mayo and McQuesten in 2020. Construction is expected to be complete in late 2020. When finished, the new 138 kV transmission line will provide more reliable electricity to customers in the Mayo and Keno regions and be equipped to support industrial growth and development in the area, including the Victoria Gold Mine, with renewable power from the Yukon grid.

Planning work for the remainder of the Stewart to Keno City Transmission Project has been completed. Yukon Energy continues to explore funding opportunities that are needed to proceed with other stages of the project.

U.S. power companies face supply-chain crisis this summer

U.S. Power Grid Supply Shortages strain reliability as heat waves, hurricanes, and drought drive peak demand; transformer scarcity, gas constraints, and renewable delays raise outage risks across ERCOT and MISO, prompting FERC warnings.

 

Key Points

They are equipment and fuel constraints that, amid extreme weather and peak demand, elevate outage risks.

✅ Transformer shortages delay storm recovery and repairs.

✅ Record gas burn, low hydro tighten generation capacity.

✅ ERCOT and MISO warn of rolling outages in heat waves.

 

U.S. power companies are facing supply crunches amid the U.S. energy crisis that may hamper their ability to keep the lights on as the nation heads into the heat of summer and the peak hurricane season.

Extreme weather events such as storms, wildfires and drought are becoming more common in the United States. Consumer power use is expected to hit all-time highs this summer, reflecting unprecedented electricity demand across the Eastern U.S., which could strain electric grids at a time when federal agencies are warning the weather could pose reliability issues.

Utilities are warning of supply constraints for equipment, which could hamper efforts to restore power during outages. They are also having a tougher time rebuilding natural gas stockpiles for next winter, after the Texas power system failure highlighted cold-weather vulnerabilities, as power generators burn record amounts of gas following the shutdown of dozens of coal plants in recent years and extreme drought cuts hydropower supplies in many Western states.

"Increasingly frequent cold snaps, heat waves, drought and major storms continue to challenge the ability of our nation’s electric infrastructure to deliver reliable affordable energy to consumers," Richard Glick, chairman of the U.S. Federal Energy Regulatory Commission (FERC), said earlier this month.

Federal agencies responsible for power reliability like FERC have warned that grids in the western half of the country could face reliability issues this summer as consumers crank up air conditioners to escape the heat, with nationwide blackout risks not limited to Texas. read more

Some utilities have already experienced problems due to the heat. Texas' grid operator, the Electric Reliability Council of Texas (ERCOT), was forced to urge customers to conserve energy as the Texas power grid faced another crisis after several plants shut unexpectedly during an early heat wave in mid-May. read more

In mid-June, Ohio-based American Electric Power Co (AEP.O) imposed rolling outages during a heat wave after a storm damaged transmission lines and knocked out power to over 200,000 homes and businesses.

The U.S. Midwest faces the most severe risk because demand is rising while nuclear and coal power supplies have declined. read more

The Midcontinent Independent System Operator (MISO), which operates the grid from Minnesota to Louisiana, warned that parts of its coverage area are at increased risk of temporary outages to preserve the integrity of the grid.

Supply-chain issues have already delayed the construction of renewable energy projects across the country, and the aging U.S. grid is threatening progress on renewables and EVs. Those renewable delays coupled with tight power in the Midwest prompted Wisconsin's WEC Energy Group Inc (WEC.N) and Indiana's NiSource Inc (NI.N) to delay planned coal plant shutdowns in recent months.

BRACING FOR SUPPLY SHORTAGES
Utility operators are conserving their inventory of parts and equipment as they plan to prevent summer power outages during severe storms. Over the last several months, that means operators have been getting creative.

"We’re doing a lot more splicing, putting cables together, instead of laying new cable because we're trying to maintain our new cable for inventory when we need it," Nick Akins, chief executive of AEP, said at the CERAWeek energy conference in March.

Transformers, which often sit on top of electrical poles and convert high-voltage energy to the power used in homes, are in short supply.

New Jersey-based Public Service Enterprise Group Inc (PSEG) (PEG.N) Chief Executive Ralph Izzo told Reuters the company has had to look at alternate supply options for low voltage transformers.

"You don’t want to deplete your inventory because you don't know when that storm is coming, but you know it's coming," Izzo said.

Some utilities are facing waiting times of more than a year for transformer parts, the National Rural Electric Cooperative Association and the American Public Power Association told U.S. Energy Secretary Jennifer Granholm in a May letter.

Summer is just starting, but U.S. weather so far this year has already been about 21% warmer than the 30-year norm, according to data provider Refinitiv.

"If we have successive days of 100-degree-heat, those pole top transformers, they start popping like Rice Krispies, and we would not have the supply stack to replace them," Izzo said.
