With Duke Energy dangling money to help pay for buried power lines, the city of Greenville is studying five areas where the conversion could start.

City Manager Jim Bourey declined to identify the pilot areas specifically but said they areas include an older, heavily treed residential area; a redevelopment area; a commercial area; a "larger lot" development area; and a major residential street.

A little more than a year after a devastating ice storm - the seventh in 10 years - caused six deaths and knocked out power to half a million local people, Duke has ended years of resistance by agreeing to divert a slice of local revenues into a burial fund.

The Greenville News had reported that burying lines would cost a fraction of Duke's previous estimates if a gradual effort focused on residential areas. Studies show underground lines can dramatically reduce power outages.

Under the new agreement, Duke would match money contributed by cities by putting up to half a percent of its local revenues - or about $364,000 a year in Greenville - into a fund. Utilities such as South Carolina Electric & Gas have offered such a plan in the Midlands for a decade.

City resident Brad Bays said it's "a great result," and the product of public pressure to mitigate storm damage.

Bourey said the effort by a city task force includes looking for ways to match Duke's money, figuring out how to involve citizens and recommending an approach to the City Council.

The city puts its $2 million annual franchise fee from Duke into its general fund.

The News reported last year that Duke's internal estimates show it would cost an average of $284,000 a mile to put residential power lines underground.

There are 107 miles of residential lines in the city.

Bourey said the task force, including utility officials, experts and citizens, is now studying specific costs such as trenching versus boring, burying under sidewalks or under roads.

He said there have been some discussions of using the burial fund to help pay for the drop line that connects a home to the power system.

Bourey said property owners have to be involved because there are added costs to hook into the system and bury other utility lines on the same poles.

He said specifics should emerge within a few months.

Bays said the areas most prone to ice storm damage and power outages should be buried first - likely the most difficult projects in the most heavily treed neighborhoods.

Still, despite digging and tree work that could rankle some residents, he believes the end result could benefit everyone.

"You can restore it where it's in like condition as before," Bays said. "It just depends on (the city's) attitude."

Alberta Advances Electricity Plans with Rate of Last Resort

Alberta Rate of Last Resort provides a baseline electricity price, boosting energy reliability, affordability, and consumer protection amid market volatility, aligning with grid modernization, integration, pricing transparency, and oversight from the Alberta Utilities Commission.

 

Key Points

A fallback electricity rate ensuring affordable, reliable power and consumer protection during market volatility.

✅ Guarantees a stable baseline price when markets spike

✅ Supports vulnerable customers lacking competitive offers

✅ Overseen by AUC to balance protection and competition

 

The Alberta government has announced significant strides in its electricity market reforms, unveiling a new plan under new electricity rules that aims to enhance energy reliability and affordability for consumers. This initiative, highlighted by the introduction of a "rate of last resort," is a critical response to ongoing challenges in the province's electricity sector, particularly following recent market volatility and increasing consumer concerns about rising electricity prices across the province.

Understanding the Rate of Last Resort

The "rate of last resort" (RLR) is designed to ensure that all Albertans have access to affordable electricity, even when they face challenges securing a competitive rate in the open market. This measure is particularly beneficial for those who may not have the means or the knowledge to navigate complex energy contracts, such as low-income families or seniors.

Under this new plan, the RLR will serve as a safety net, guaranteeing a stable and predictable rate for customers who find themselves without a competitive provider. This move is seen as a crucial step in addressing the needs of vulnerable populations who might otherwise be at risk of being shut out of the energy market.

Market Volatility and Consumer Protection

Alberta's electricity market has faced significant fluctuations over the past few years, and is headed for a reshuffle as policymakers respond to unpredictability in pricing and service availability. The rise in energy costs has caused distress among consumers, with many advocating for stronger protections against sudden price hikes.

The government's recent decision to implement the RLR is a direct acknowledgment of these concerns. By creating a baseline rate, officials aim to provide consumers with peace of mind, knowing that there is a fallback option should market conditions turn unfavorable. This initiative complements other measures aimed at enhancing consumer protections, including improved transparency in pricing, the consumer price cap on power bills being advanced, and the regulation of energy suppliers.

Broader Implications for Alberta’s Energy Landscape

This plan is not only about consumer protection; it also represents a broader shift towards a more sustainable and stable energy market in Alberta, aligning with proposed electricity market changes under consideration. The introduction of the RLR is part of a comprehensive strategy that includes investments in renewable energy and infrastructure improvements. By modernizing the grid and promoting cleaner energy sources, the government aims to reduce dependency on fossil fuels while maintaining reliability and affordability.

Additionally, this move aligns with the province's goals to meet climate targets and transition to a more sustainable energy future as Alberta is changing how it produces and pays for electricity through policy updates. As the demand for clean energy grows, Alberta is positioning itself to be a leader in this transformation, appealing to both residents and businesses committed to sustainability.

Public and Industry Reactions

The announcement has garnered mixed reactions from various stakeholders. While consumer advocacy groups have largely praised the government's efforts to protect consumers and ensure affordable electricity, some industry experts express concerns about potential long-term impacts on competition, arguing the market needs competition to remain dynamic. They argue that while the RLR provides immediate relief, it could disincentivize companies from offering competitive rates, leading to a less dynamic market in the future.

The Alberta Utilities Commission (AUC) is expected to play a pivotal role in overseeing the implementation of the RLR, ensuring that it operates effectively and that any unintended consequences are addressed swiftly. This regulatory oversight will be crucial in balancing consumer protection with the need for a competitive energy market.

Conclusion

As Alberta forges ahead with its electricity market reforms, the introduction of the rate of last resort marks a significant step in enhancing consumer protection and ensuring energy affordability. While challenges remain, the government's proactive approach reflects a commitment to addressing the needs of all Albertans, particularly those most vulnerable to market fluctuations.

In this evolving energy landscape, the RLR will serve not only as a safety net for consumers but also as a foundation for a more sustainable and reliable electricity system. As Alberta continues to adapt to changing energy demands and climate considerations, the effectiveness of these measures will be closely monitored, shaping the future of the province’s electricity market.

Renewables are not making electricity any more expensive

Renewables' Impact on US Wholesale Electricity Prices is clear: DOE analysis shows wind and solar, capacity gains, and natural gas lowering rates, shifting daily patterns, and triggering occasional negative pricing in PJM and ERCOT.

 

Key Points

DOE data show wind and solar lower wholesale prices, reshape price curves, and cause negative pricing in markets.

✅ Natural gas price declines remain the largest driver of cheaper power

✅ Wind and solar shift seasonal and time-of-day price patterns

✅ Negative wholesale prices appear near high wind and solar output

 

One of the arguments that's consistently been raised against doing anything about climate change is that it will be expensive. On the more extreme end of the spectrum, there have been dire warnings about plunging standards of living due to skyrocketing electricity prices. The plunging cost of renewables like solar cheaper than gas has largely silenced these warnings, but a new report from the Department of Energy suggests that, even earlier, renewables were actually lowering the price of electricity in the United States.

 

Plunging prices
The report focuses on wholesale electricity prices in the US. Note that these are distinct from the prices consumers actually pay, which includes taxes, fees, payments to support the grid that delivers the electricity, and so on. It's entirely possible for wholesale electricity prices to drop even as consumers end up paying more, and market reforms determine how those changes are passed through. That said, large changes in the wholesale price should ultimately be passed on to consumers to one degree or another.

The Department of Energy analysis focuses on the decade between 2008 and 2017, and it includes an overall analysis of the US market, as well as large individual grids like PJM and ERCOT and, finally, local prices. The decade saw a couple of important trends: low natural gas prices that fostered a rapid expansion of gas-fired generators and the rapid expansion of renewable generation that occurred concurrently with a tremendous drop in price of wind and solar power.

Much of the electricity generated by renewables in this time period would be more expensive than that generated by wind and solar installed today. Not only have prices for the hardware dropped, but the hardware has improved in ways that provide higher capacity factors, meaning that they generate a greater percentage of the maximum capacity. (These changes include things like larger blades on wind turbines and tracking systems for solar panels.) At the same time, operating wind and solar is essentially free once they're installed, so they can always offer a lower price than competing fossil fuel plants.

With those caveats laid out, what does the analysis show? Almost all of the factors influencing the wholesale electricity price considered in this analysis are essentially neutral. Only three factors have pushed the prices higher: the retirement of some plants, the rising price of coal, and prices put on carbon, which only affect some of the regional grids.

In contrast, the drop in the price of natural gas has had a very large effect on the wholesale power price. Depending on the regional grid, it's driven a drop of anywhere from $7 to $53 per megawatt-hour. It's far and away the largest influence on prices over the past decade.

 

Regional variation and negative prices
But renewables have had an influence as well. That influence has ranged from roughly neutral to a cost reduction of $2.2 per MWh in California, largely driven by solar. While the impact of renewables was relatively minor, it is the second-largest influence after natural gas prices, and the data shows that wind and solar are reducing prices rather than increasing them.

The reports note that renewables are influencing wholesale prices in other ways, however. The growth of wind and solar caused the pattern of seasonal price changes to shift in areas of high wind and solar, as seen with solar reshaping prices in Northern Europe as daylight hours and wind patterns shift with the seasons. Similarly, renewables have a time-of-day effect for similar reasons, helping explain why the grid isn't 100% renewable today, which also influences the daily timing price changes, something that's not an issue with fossil fuel power.

US DOE
One striking feature of areas where renewable power is prevalent is that there are occasional cases in which an oversupply of renewable energy produces negative electricity prices in the wholesale market. (In the least-surprising statement in the report, it concludes that "negative prices in high-wind and high-solar regions occurred most frequently in hours with high wind and solar output.") In most areas, these negative prices are rare enough that they don't have a significant influence on the wholesale price.

That's not true everywhere, however. Areas on the Great Plains see fairly frequent negative prices, and they're growing in prevalence in areas like California, the Southwest, and the northern areas of New York and New England, while negative prices in France have been observed in similar conditions. In these areas, negative wholesale prices near solar plants have dropped the overall price by 3%. Near wind plants, that figure is 6%.

None of this is meant to indicate that there are no scenarios where expanded renewable energy could eventually cause wholesale prices to rise. At sufficient levels, the need for storage, backup plants, and grid management could potentially offset their low costs, a dynamic sometimes referred to as clean energy's dirty secret by analysts. But it's clear we have not yet reached that point. And if the prices of renewables continue to drop, then that point could potentially recede fast enough not to matter.

Inside Copenhagen’s race to be the first carbon-neutral city

Hedonistic Sustainability turns Copenhagen's ARC waste-to-energy plant into a public playground, blending ski slope, climbing wall, and trails with carbon-neutral heating, renewables, circular economy design, and green growth for climate action and liveability.

 

Key Points

A design approach fusing public recreation with clean-energy infrastructure to drive carbon-neutral, livable urban growth.

✅ Waste-to-energy plant doubles as recreation hub

✅ Supports carbon-neutral heating and renewables

✅ Stakeholder-driven, scalable urban climate model

 

“We call it hedonistic sustainability,” says Jacob Simonsen of the decision to put an artificial ski slope on the roof of the £485m Amager Resource Centre (Arc), Copenhagen’s cutting-edge new waste-to-energy power plant that feeds the city’s district heating network as well. “It’s not just good for the environment, it’s good for life.”

Skiing is just one of the activities that Simonsen, Arc’s chief executive, and Bjarke Ingels, its lead architect, hope will enhance the latest jewel in Copenhagen’s sustainability crown. The incinerator building also incorporates hiking and running trails, a street fitness gym and the world’s highest outdoor climbing wall, an 85-metre “natural mountain” complete with overhangs that rises the full height of the main structure.

In Copenhagen, green transformation goes hand-in-hand with job creation, a growing economy and a better quality of life

Frank Jensen, lord mayor

It’s all part of Copenhagen’s plan to be net carbon-neutral by 2025. Even now, after a summer that saw wildfires ravagethe Arctic Circle and ice sheets in Greenland suffer near-record levels of melt, the goal seems ambitious. In 2009, when the project was formulated, it was positively revolutionary.

“A green, smart, carbon-neutral city,” declared the cover of the climate action plan, aligning with a broader electric planet vision, before detailing the scale of the challenge: 100 new wind turbines; a 20% reduction in both heat and commercial electricity consumption; 75% of all journeys to be by bike, on foot, or by public transport; the biogas-ification of all organic waste; 60,000 sq metres of new solar panels; and 100% of the city’s heating requirements to be met by renewables.

Radical and far-reaching, the scheme dared to rethink the very infrastructure underpinning the city. There’s still not a climate project anywhere else in the world that comes close, even as leaders elsewhere champion a fully renewable grid by 2030.

And, so far, it’s working. CO2 emissions have been reduced by 42% since 2005, and while challenges around mobility and energy consumption remain (new technologies such as better batteries and carbon capture are being implemented, and global calls for clean electricity investment grow), the city says it is on track to achieve its ultimate goal.

More significant still is that Copenhagen has achieved this while continuing to grow in traditional economic terms. Even as some commentators insist that nothing short of a total rethink of free-market economics and corporate structures is required to stave off global catastrophe, the Danish capital’s carbon transformation has happened alongside a 25% growth in its economy over two decades. Copenhagen’s experience will be a model for other world cities as the global energy transition unfolds.

The sentiment that lies behind Arc’s conception as a multi-use public good – “hedonistic sustainability” – is echoed by Bo Asmus Kjeldgaard, former mayor of Copenhagen for the environment and the man originally tasked, back in 2010, with making the plan a reality.

“We combined life quality with sustainability and called it ‘liveability’,” says Kjeldgaard, now CEO of his own climate adaptation company, Greenovation. “We succeeded in building a good narrative around this, one that everybody could believe in.”

The idea was first floated in the late 1990s, when the newly elected Kjeldgaard had a vision of Copenhagen as the environmental capital of Europe. His enthusiasm ran into political intransigence, however, and despite some success, a lack of budget meant most of his work became “just another branding exercise – it was greenwashing”.

We’re such a rich country – change should be easy for us

Claus Nielsen, furniture maker and designer

But after stints as mayor of family and the labour market, and children and young people, he ended up back at environment in 2010 with renewed determination and, crucially, a broader mandate from the city council. “I said: ‘This time, we have to do it right,’” he recalls, “so we made detailed, concrete plans for every area, set the carbon target, and demanded the money and the manpower to make it a reality.”

He brought on board more than 200 stakeholders, from businesses to academia to citizen representatives, and helped them develop 22 specific business plans and 65 separate projects. So far the plan appears on track: there has been a 15% reduction in heat consumption, 66% of all trips in the city are now by bike, on foot or public transport, and 51% of heat and power comes from renewable electricity sources.

The onus placed on ordinary Copenhageners to walk and cycle more, pay higher taxes (especially on cars) and put up with the inconvenience of infrastructure construction has generally been met with understanding and good grace. And while some people remain critical of the fact that Copenhagen airport is not factored into the CO2 calculations – it lies beyond the city’s boundaries – and grumble about precise definitions and formulae, dissent has been rare.

This relative lack of nimbyism and carping about change can, says Frank Jensen, the city’s lord mayor, be traced to longstanding political traditions.

“Caring for the environment and taking responsibility for society in general has been an integral part of the upbringing of many Danes,” he says. “Moreover, there is a general awareness that climate change now calls for immediate, ambitious and collective action.” A 2018 survey by Concito, a thinktank, found that such action was a top priority for voters.

Jensen is keen to stress the cooperative nature of the plan and says “our visions have to be grounded in the everyday lives of people to be politically feasible”. Indeed, involving so many stakeholders, and allowing them to actively help shape both the ends and the means, has been key to the plan’s success so far and the continued goodwill it enjoys. “It’s so important to note that we [the authorities] cannot do this alone,” says Jørgen Abildgaard, Copenhagen’s executive climate programme director.

Many businesses around the world have typically been reluctant to embrace sustainability when a dip in profits or inconvenience might be the result, but not in Copenhagen. Martin Manthorpe, director of strategy, business development and public affairs at NCC, one of Scandinavia’s largest construction and industrial groups, was brought in early on by Abildgaard to represent industry on the municipality’s climate panel, and to facilitate discussions with the wider business community. He thinks there are several reasons why.

“The Danes have a trading mindset, meaning ‘What will I have to sell tomorrow?’ is just as important as ‘What am I producing today?’” he says. “Also, many big Danish companies are still ultimately family-owned, so the culture leans more towards long-term thinking.”

It is, he says, natural for business to be concerned with issues around sustainability and be willing to endure short-term pain: “To do responsible, long-term business, you need to see yourself as part of the larger puzzle that is called ‘society’.”

Furthermore, in Denmark climate change denial is given extremely short shrift. “We believe in the science,” says Anders Haugaard, a local entrepreneur. “Why wouldn’t you? We’re told sustainability brings only benefits and we’ve got no reason to be suspicious.”

“No one would dare argue against the environment,” says his friend Claus Nielsen, a furniture maker and designer. “We’re such a rich country – change should be easy for us.” Nielsen talks about how enlightened his kids are – “my 11-year-old daughter is now a flexitarian ” – and says that nowadays he mainly buys organic; Haugaard doesn’t see a problem with getting rid of petrol cars (the whole country is aiming to be fossil fuel-free by 2050 as the EU electricity use by 2050 is expected to double).

Above all, there’s a belief that sustainability need not make the city poorer: that innovation and “green growth” can be lucrative in and of themselves. “In Copenhagen, green transformation goes hand-in-hand with job creation, a growing economy and a better quality of life,” says Jensen. “We have also shown that it’s possible to combine this transition with economic growth and market opportunities for businesses, and I think that other countries can learn from our example.”

Besides, as Jensen notes, there is little alternative, and even less time: “National states have failed to take enough responsibility, but cities have the power and will to create concrete solutions. We need to start accelerating their implementation – we need to act now.”

Big prizes awarded to European electricity prediction specialists

Electricity Grid Flow Prediction leverages big data, machine learning, and weather analytics to forecast power flows across smart grids, enhancing reliability, reducing blackouts and curtailment, and optimizing renewable integration under EU Horizon 2020 innovation.

 

Key Points

Short-term forecasting of power flows using big data, weather inputs, and machine learning to stabilize smart grids.

✅ Uses big data, weather, and ML for 6-hour forecasts

✅ Improves reliability, cuts blackouts and energy waste

✅ Supports smart grids, renewables, and grid balancing

 

Three European prediction specialists have won prizes worth €2 million for developing the most accurate predictions of electricity flow through a grid

The three winners of the Big Data Technologies Horizon Prize received their awards at a ceremony on 12th November in Austria.

The first prize of €1.2 million went to Professor José Vilar from Spain, while Belgians Sofie Verrewaere and Yann-Aël Le Borgne came in joint second place and won €400,000 each.

The challenge was open to individuals groups and organisations from countries taking part in the EU’s research and innovation programme, Horizon 2020.

Carlos Moedas, Commissioner for Research, Science and Innovation, said: “Energy is one of the crucial sectors that are being transformed by the digital grid worldwide.

“This Prize is a good example of how we support a positive transformation through the EU’s research and innovation programme, Horizon 2020.

“For the future, we have designed our next programme, Horizon Europe, to put even more emphasis on the merger of the physical and digital worlds across sectors such as energy, transport and health.”

The challenge for the applicants was to create AI-driven software that could predict the likely flow of electricity through a grid taking into account a number of factors including the weather and the generation source (i.e. wind turbines, solar cells, etc).

Using a large quantity of data from electricity grids, EU smart meters, combined with additional data such as weather conditions, applicants had to develop software that could predict the flow of energy through the grid over a six-hour period.

Commissioner for Digital Economy and Society Mariya Gabriel said: “The wide range of possible applications of these winning submissions could bring tangible benefits to all European citizens, including efforts to tackle climate change with machine learning across sectors.”

The decision to focus on energy grids for this particular prize was driven by a clear market need, including expanding HVDC technology capabilities.

Today’s energy is produced at millions of interconnected and dispersed unpredictable sites such as wind turbines, solar cells, etc., so it is harder to ensure that electricity supply matches the demand at all times.

This complexity means that huge amounts of data are produced at the energy generation sites, in the grid and at the place where the energy is consumed.

Being able to make accurate, short-term predictions about power grid traffic is therefore vital to reduce the risks of blackouts or, by enabling utilities to use AI for energy savings, limit waste of energy.

Reliable predictions can also be used in fields such as biology and healthcare. The predictions can help to diagnose and cure diseases as well as to allocate resources where they are most needed.

Ultimately, the winning ideas are set to be picked up by the energy sector in the hopes of creating smarter electricity infrastructure, more economic and more reliable power grids.

Electricity Grids Can Handle Electric Vehicles Easily - They Just Need Proper Management

EV Grid Capacity Management shows how smart charging, load balancing, and off-peak pricing align with utility demand response, DC fast charging networks, and renewable integration to keep national electricity infrastructure reliable as EV adoption scales

 

Key Points

EV Grid Capacity Management schedules charging and balances load to keep EV demand within utility capacity.

✅ Off-peak pricing and time-of-use tariffs shift charging demand.

✅ Smart chargers enable demand response and local load balancing.

✅ Gradual EV adoption allows utilities to plan upgrades efficiently.

 

One of the most frequent concerns you will see from electric vehicle haters is that the electricity grid can’t possibly cope with all cars becoming EVs, or that EVs will crash the grid entirely. However, they haven’t done the math properly. The grids in most developed nations will be just fine, so long as the demand is properly management. Here’s how.

The biggest mistake the social media keyboard warriors make is the very strange assumption that all cars could be charging at once. In the UK, there are currently 32,697,408 cars according to the UK Department of Transport. The UK national grid had a capacity of 75.8GW in 2020. If all the cars in the UK were EVs and charging at the same time at 7kW (the typical home charger rate), they would need 229GW – three times the UK grid capacity. If they were all charging at 50kW (a common public DC charger rate), they would need 1.6TW – 21.5 times the UK grid capacity. That sounds unworkable, and this is usually the kind of thinking behind those who claim the UK grid can't cope with EVs.

What they don’t seem to realize is that the chances of every single car charging all at once are infinitesimally low. Their arguments seem to assume that nobody ever drives their car, and just charges it all the time. If you look at averages, the absurdity of this position becomes particularly clear. The distance each UK car travels per year has been slowly dropping, and was 7,400 miles on average in 2019, again according to the UK Department of Transport. An EV will do somewhere between 2.5 and 4.5 miles per kWh on average, so let’s go in the middle and say 3.5 miles. In other words, each car will consume an average of 2,114kWh per year. Multiply that by the number of cars, and you get 69.1TWh. But the UK national grid produced 323TWh of power in 2019, so that is only 21.4% of the energy it produced for the year. Before you argue that’s still a problem, the UK grid produced 402TWh in 2005, which is more than the 2019 figure plus charging all the EVs in the UK put together. The capacity is there, and energy storage can help manage EV-driven peaks as well.

Let’s do the same calculation for the USA, where an EV boom is about to begin and planning matters. In 2020, there were 286.9 million cars registered in America. In 2020, while the US grid had 1,117.5TW of utility electricity capacity and 27.7GW of solar, according to the US Energy Information Administration. If all the cars were EVs charging at 7kW, they would need 2,008.3TW – nearly twice the grid capacity. If they charged at 50kW, they would need 14,345TW – 12.8 times the capacity.

However, in 2020, the US grid generated 4,007TWh of electricity. Americans drive further on average than Brits – 13,500 miles per year, according to the US Department of Transport’s Federal Highway Administration. That means an American car, if it were an EV, would need 3,857kWh per year, assuming the average efficiency figures above. If all US cars were EVs, they would need a total of 1,106.6TWh, which is 27.6% of what the American grid produced in 2020. US electricity consumption hasn’t shrunk in the same way since 2005 as it has in the UK, but it is clearly not unfeasible for all American cars to be EVs. The US grid could cope too, even as state power grids face challenges during the transition.

After all, the transition to electric isn’t going to happen overnight. The sales of EVs are growing fast, with for example more plug-ins sold in the UK in 2021 so far than the whole of the previous decade (2010-19) put together. Battery-electric vehicles are closing in on 10% of the market in the UK, and they were already 77.5% of new cars sold in Norway in September 2021. But that is new cars, leaving the vast majority of cars on the road fossil fuel powered. A gradual introduction is essential, too, because an overnight switchover would require a massive ramp up in charge point installation, particularly devices for people who don’t have the luxury of home charging. This will require considerable investment, but could be served by lots of chargers on street lamps, which allegedly only cost £1,000 ($1,300) each to install, usually with no need for extra wiring.

This would be a perfectly viable way to provide charging for most people. For example, as I write this article, my own EV is attached to a lamppost down the street from my house. It is receiving 5.5kW costing 24p (32 cents) per kWh through SimpleSocket, a service run by Ubitricity (now owned by Shell) and installed by my local London council, Barnet. I plugged in at 11am and by 7.30pm, my car (which was on about 28% when I started) will have around 275 miles of range – enough for a couple more weeks. It will have cost me around £12 ($16) – way less than a tank of fossil fuel. It was a super-easy process involving the scanning of a QR code and entering of a credit card, very similar to many parking systems nowadays. If most lampposts had one of these charging plugs, not having off-street parking would be no problem at all for owning an EV.

With most EVs having a range of at least 200 miles these days, and the average mileage per day being 20 miles in the UK (the 7,400-mile annual figure divided by 365 days) or 37 miles in the USA, EVs won’t need charging more than once a week or even every week or two. On average, therefore, the grids in most developed nations will be fine. The important consideration is to balance the load, because if too many EVs are charging at once, there could be a problem, and some regions like California are looking to EVs for grid stability as part of the solution. This will be a matter of incentivizing charging during off-peak times such as at night, or making peak charging more expensive. It might also be necessary to have the option to reduce charging power rates locally, while providing the ability to prioritize where necessary – such as emergency services workers. But the problem is one of logistics, not impossibility.

There will be grids around the world that are not in such a good place for an EV revolution, at least not yet, and some critics argue that policies like Canada's 2035 EV mandate are unrealistic. But to argue that widespread EV adoption will be an insurmountable catastrophe for electricity supply in developed nations is just plain wrong. So long as the supply is managed correctly to make use of spare capacity when it’s available as much as possible, the grids will cope just fine.

Alberta Leads the Way in Agrivoltaics

Agrivoltaics in Alberta integrates solar energy with agriculture, boosting crop yields and water conservation. The Strathmore Solar project showcases dual land use, sheep grazing for vegetation control, and PPAs that expand renewable energy capacity.

 

Key Points

A dual-use model where solar arrays and farming co-exist, boosting yields, saving water, and diversifying revenue.

✅ Strathmore Solar: 41 MW on 320 acres with managed sheep grazing

✅ 25-year TELUS PPA secures power and renewable energy credits

✅ Panel shade cuts irrigation needs and protects crops from extremes

 

Alberta is emerging as a leader in agrivoltaics—the innovative practice of integrating solar energy production with agricultural activities, aligning with the province's red-hot solar growth in recent years. This approach not only generates renewable energy but also enhances crop yields, conserves water, and supports sustainable farming practices. A notable example of this synergy is the Strathmore Solar project, a 41-megawatt solar farm located on 320 acres of leased industrial land owned by the Town of Strathmore. Operational since March 2022, it exemplifies how solar energy and agriculture can coexist and thrive together.

The Strathmore Solar Initiative

Strathmore Solar is a collaborative venture between Capital Power and the Town of Strathmore, with a 25-year power purchase agreement in place with TELUS Corporation for all the energy and renewable energy credits generated by the facility. The project not only contributes significantly to Alberta's renewable energy capacity, as seen with new solar facilities contracted at lower cost across the province, but also serves as a model for agrivoltaic integration. In a unique partnership, 400 to 600 sheep from Whispering Cedars Ranch are brought in to graze the land beneath the solar panels. This arrangement helps manage vegetation, reduce fire hazards, and maintain the facility's upkeep, all while providing shade for the grazing animals. This mutually beneficial setup maximizes land use efficiency and supports local farming operations, illustrating how renewable power developers can strengthen outcomes with integrated designs today. 

Benefits of Agrivoltaics in Alberta

The integration of solar panels with agricultural practices offers several advantages for a province that is a powerhouse for both green energy and fossil fuels already across sectors:

  • Enhanced Crop Yields: Studies have shown that crops grown under solar panels can experience increased yields due to reduced water evaporation and protection from extreme weather conditions.

  • Water Conservation: The shade provided by solar panels helps retain soil moisture, leading to a decrease in irrigation needs.

  • Diversified Income Streams: Farmers can generate additional revenue by selling renewable energy produced by the solar panels back to the grid.

  • Sustainable Land Use: Agrivoltaics allows for dual land use, enabling the production of both food and energy without the need for additional land.

These benefits are evident in various agrivoltaic projects across Alberta, where farmers are successfully combining crop cultivation with solar energy production amid a renewable energy surge that is creating thousands of jobs.

Challenges and Considerations

While agrivoltaics presents numerous benefits, there are challenges to consider as Alberta navigates challenges with solar expansion today across Alberta:

  • Initial Investment: The setup costs for agrivoltaic systems can be high, requiring significant capital investment.

  • System Maintenance: Regular maintenance is essential to ensure the efficiency of both the solar panels and the agricultural operations.

  • Climate Adaptability: Not all crops may thrive under the conditions created by solar panels, necessitating careful selection of suitable crops.

Addressing these challenges requires careful planning, research, and collaboration between farmers, researchers, and energy providers.

Future Prospects

The success of projects like Strathmore Solar and other agrivoltaic initiatives in Alberta indicates a promising future for this dual-use approach. As technology advances and research continues, agrivoltaics could play a pivotal role in enhancing food security, promoting sustainable farming practices, and contributing to Alberta's renewable energy goals. Ongoing projects and partnerships aim to refine agrivoltaic systems, making them more efficient and accessible to farmers across the province.

The integration of solar energy production with agriculture in Alberta is not just a trend but a transformative approach to sustainable farming. The Strathmore Solar project serves as a testament to the potential of agrivoltaics, demonstrating how innovation can lead to mutually beneficial outcomes for both the agricultural and energy sectors.
