Scandinavia is cold enough to grow a Mats Sundin. Yet nowadays nearly everyone in the hockey hero's native Sweden keeps warm in winter without burning so much as a drop of oil.

Such are the spoils of the Nordic energy paradox, where a generation of pragmatic energy policy is putting paid to the notion that life cannot prosper on a lower-carbon diet.

For those who would have their cake and eat it, too, look to Sweden, where the raw data is to be envied: between 1990 and 2006, the country enjoyed economic growth of 44 per cent in fixed prices, even as it cut carbon emissions by 9 per cent.

Denmark's numbers show a similar decoupling of GDP from the use of fossil fuels, with 43-per-cent growth contrasting with a 14-per-cent carbon reduction in the same time frame.

The shift was driven by a complex array of policies. But at its root, experts say, was the world's first carbon tax on fossil fuels – an early version of the so-called green shift now under discussion in Canada.

"We are living proof the world should not fear a tax on carbon. Sweden has the highest carbon taxation in the world but we are not living in the Stone Age," said Per Rosenqvist, a climate expert with the Swedish Environment Ministry.

"The standard of life here has improved even as emissions came down. It hasn't been easy. It takes a range of policies, not just a tax. The solutions are different in every country. And they need to be regularly readjusted, as we learn from our mistakes. But it works."

Those with long memories may recall the best of these results match the promises made by the Nordic countries a full 20 years ago, when they first committed to unilaterally weaning their economies off carbon at the 1988 Toronto Conference on The Changing Atmosphere.

In fact, Scandinavia had been brooding over energy issues long before the summit in Toronto. Energy experts say the flashpoint came in 1973, when the first wave of OPEC embargoes shocked the then import-dependent Nordic nations.

"More than any other country, Denmark was severely hit by the 1973 crisis because at the time 95 per cent of our energy was imported oil and coal," said Ole Odgaard, a senior adviser to the Danish Energy Agency.

"It was a very deep shock. And out of this came a determination to rethink our entire energy strategy in order to avoid the same thing happening again."

It is almost required, when writing about Scandinavian energy policy, to wax breathless about enlightened nations who put the planet uppermost on their national agendas.

Yet the reality is something somewhat less angelic. The Danish and Swedish models are driven as much by hard-nosed pragmatism as anything else. Enlightened? Absolutely. Daring? That, too. But the imperative, as with any nation, was self-interest, first and foremost.

"There is also a cultural explanation: We tend to have a culture of consensus on the really important issues," said Odgaard. "It goes back hundreds of years in Denmark, that tradition of finding a common strategy. And we saw it come together again after the crisis of the 1970s. We decided as a society that the issue of energy was so vital that we would raise it above politics – and ever since, that broad consensus has endured. The broad political alliance behind our strategy extends throughout parliament, and as a result the government can change but the basic policy endures."

The Danish consensus, said Odgaard, enabled Denmark to begin drafting plans for the extensive district heating networks that today provide 60 per cent of the country's winter warmth, from the whole of Copenhagen to isolated rural farms. Much of that heat comes from cogeneration plants that harvest heat energy previously wasted in electricity production.

"The district heating is the main reason we saved six to 11 million tonnes of CO2 per year," he said.

Though the bulk of Denmark's carbon tax burden is borne by consumers in fuel and electricity bills, industry pays, as well, albeit at a lower rate – heavy industry has long complained it is suffering a competitive disadvantage.

"When Canada goes shopping for policy, please take wisdom from our mistakes. Because the fact is we face carbon leakage issues in Denmark – the fear of losing our energy-heavy industry to places like Russia and North Africa," said Helle Juhler-Verdoner, head of the Danish Federation of Industries' energy unit.

"I'm not saying the carbon tax hasn't helped improve efficiency. We are, of course, fine with that. But we argue that a better model is to assist the new energy technologies through other means, rather than forcing energy-intensive companies to pay for it."

Juhler-Verdoner points jealously to Sweden, where most major industries – cement, steel, aluminium, pulp and paper – enjoy handsome exemptions from carbon taxation. Swedish policy, she said, allows heavy industry to more easily compete in the global marketplace.

Though they are neighbours, Denmark and Sweden have shifted away from fossil fuels in distinctly different ways. Though both have realized significant energy savings in ultra-efficient cogeneration heat/electricity plants, the Danes have embraced wind as their flag-bearing renewable energy, whereas the forest-rich Swedes have turned to biomass.

In both cases, the shift has resulted in a second dividend of emerging energy technology industries, with Denmark's Vestas Wind Systems alone, at 15,000 employees and growing, accounting for a quarter of the burgeoning global market for wind turbines.

Put another way, Danish energy technology exports were negligible in 1992, accounting for less than 1 per cent of total exports. Last year, Vestas and other burgeoning Danish energy technologies accounted for 9.2 per cent of total exports, worth 52 billion Danish Kroners, or $10.5 billion.

In Sweden, the economic gains are more difficult to pinpoint. While the Swedish home appliance conglomerate Electrolux, for example, is a global giant that routinely wins awards for its emphasis on energy efficiency, many argue carbon taxation played a minor role in the company's search for energy savings.

Swedish biomass and geothermal heat production, on the other hand, have become industries in their own right and now account for nearly 100 per cent of Sweden's district heating supply.

"By exempting biomass from the carbon tax we're made a dramatic shift away from coal in fuelling our power plants," said Rosenqvist.

"But it has also created an industry that would probably be of interest to Canada, given your forests. What we do is extract the biomass from growing forests, by using the residues that would otherwise be rotting and releasing CO2 in the process."

Though very much a society of car-lovers, Sweden is seeing a rapid fuel shift toward ethanol. The change is driven both by the carbon tax, and by a supplementary government edict requiring all filling stations to offer at least one alternative fuel in addition to gas or diesel. Ethanol now accounts for more than 25 per cent of the market, said Rosenqvist.

Swedish and Danish officials alike stress that carbon taxes don't succeed in and of themselves. To achieve results, they must be paired with comprehensive incentives and subsidies that build toward the desired energy shift.

"The advantage of leading the world in some of these areas is obvious. The disadvantage is that we made some mistakes," said Odgaard.

"For example, the first of the land-based windmills were built without any procedure to gain public acceptance. They caused landscape pollution and now we are paying to pull them down and re-establish better, more efficient ones in better locations," he said.

One Danish analyst describes the carbon tax as an almost Darwinian accelerator of the adapt-or-survive dilemma that all Western economies face today.

"The West is losing the heavy industrial production anyway, to China and India and wherever, because cheap labour is the real issue," said Martin Lidegaard, chair of Concito, a Danish environmental think tank.

"So what the carbon tax has done is to force the rest of our industry to go through a process of natural selection. The companies that can deliver new technologies and efficiencies survive and thrive. The companies that cannot are old and weak. And yes, let us be honest, they die," said Lidegaard. "But that's the whole point of a carbon tax. You want to pick winners that will position your economy for the future. If you make your policy to protect everybody, nothing will change."

Minnesota bill mandating 100% carbon-free electricity by 2040

Minnesota 100% Carbon-Free Electricity advances renewable energy: wind, solar, hydropower, hydrogen, biogas from landfill gas and anaerobic digestion; excludes incineration in environmental justice areas; uses renewable energy credits and streamlined permitting.

 

Key Points

Minnesota's mandate requires utilities to deliver 100% carbon-free power by 2040 with targets and EJ safeguards.

✅ Utilities must hit 90% carbon-free by 2035; 100% by 2040.

✅ Incineration in EJ areas excluded; biogas, wind, solar allowed.

✅ Compliance via renewable credits; streamlined permitting.

 

Minnesota Gov. Tim Walz, D, is expected to soon sign a bill establishing a clean electricity standard requiring utilities in the state to provide electricity from 100% carbon-free sources by 2040. The bill also calls for utilities to generate at least 55% of their electricity from renewable energy sources by 2035, a trajectory similar to New Mexico's clean electricity push underway this decade.

Electricity generated from landfill gas and anaerobic digestion are named as approved renewable energy technologies, but electricity generated from incinerators operating in “environmental justice areas”, reflecting concerns about renewable facilities violating pollution rules in some states, will not be counted toward the goal. Wind, solar, and certain hydropower and hydrogen energy sources are also considered renewable in the bill. 

The bill defines EJ areas as places where at least 40% of residents are not white, 35% of households have an income that’s below 200% of the federal poverty line, and 40% or more of residents over age 5 have “limited” English proficiency. Areas the U.S. state defines as “Indian country” are also considered EJ areas.

Some of the state’s largest electric utilities, like Xcel Energy and Minnesota Power, have already pledged to move to carbon-free energy, and utilities such as Alliant Energy have outlined carbon-neutral plans in the region, but this bill speeds up that goal by 10 years, Minnesota Public Radio reported. The bill calls for public utilities operating in the state to be 80% carbon-free and other electric utilities to be 60% carbon-free by 2030. All utilities must be 90% carbon-free by 2035 before ultimately hitting the 100% mark in 2040, according to the bill.  

The bill gives utilities some leniency if they demonstrate to state regulators that they can’t offer affordable power while working toward the benchmarks, acknowledging reliability challenges seen in places like California's grid during the clean energy transition. It also allows utilities to buy renewable energy credits to meet the standard instead of generating the energy themselves. 

Patrick Serfass, executive director of the American Biogas Council, said the bill will incentivize more biogas-related electricity projects, “which means the recycling of more organic material and more renewable electricity in the state. Those are all good things,” he said. ABC sees significant potential for biogas production in Minnesota, though the federal climate law has delivered mixed results for accelerating clean power deployment.

The bill also aims to streamline the permitting process for new energy projects in the state, even as some states consider limits on clean energy that would constrain utility use, and calls for higher minimum wage requirements for workers.

Net-zero roadmap can cut electricity costs by a third in Germany - Wartsila

Germany net-zero roadmap charts coal phase-out by 2030, rapid renewables buildout, energy storage, and hydrogen-ready gas engines to cut emissions and lower LCOE by 34%, unlocking a resilient, flexible, low-cost power system by 2040.

 

Key Points

Plan to phase out coal by 2030 and gas by 2040, scaling renewables, storage, and hydrogen to cut LCOE and emissions.

✅ Coal out by 2030; gas phased 2040 with hydrogen-ready engines

✅ Add 19 GW/yr renewables; 30 GW storage by 2040

✅ 34% lower LCOE, 23% fewer emissions vs slower path

 

Germany can achieve significant reductions in emissions and the cost of electricity by phasing out coal in 2030 under its coal phase-out plan but must have a clear plan to ramp up renewables and pivot to sustainable fuels in order to achieve net-zero, according to a new whitepaper from Wartsila.

The modelling, published in Wärtsilä new white paper ‘Achieving net-zero power system in Germany by 2040’, compares the current plan to phase out coal by 2030 and gas by 2045 with an accelerated plan, where gas is phased out by 2040. By accelerating the path to net-zero, Germany can unlock a 34% reduction in the levelised cost of energy, as well as a 23% reduction in the total emissions, or 562 million tonnes of carbon dioxide in real terms.

The modelling offers a clear, three-step roadmap to achieve net-zero: rapidly increase renewables, energy storage and begin future-proofing gas engines in this decade; phase out coal by 2030; and phase out gas by 2040, converting remaining engines to run on sustainable fuels.

The greatest rewards are available if Germany front-loads decarbonisation. This can be done by rapidly increasing renewable capacity, adding 19 GW of wind and solar PV capacity per year. It must also add a total of 30GW of energy storage by 2040.

Håkan Agnevall, President and CEO of Wärtsilä Corporation said: “Germany stands on the precipice of a new, sustainable energy era. The new Federal Government has indicated its plans to consign coal to history by 2030. However, this is only step one. Our white paper demonstrates the need to implement a three-step roadmap to achieve net-zero. It is time to put a deadline on fossil fuels and create a clear plan to transition to sustainable fuels.”

While a rapid coal phase-out has been at the centre of recent climate policy debates, including the ongoing nuclear debate over Germany’s energy mix, the pathway to net-zero is less clear. Wärtsilä’s modelling shows that gas engines should be used to accelerate the transition by providing a short-term bridge to enable net zero and navigate the energy transition while balancing the intermittency of renewables until sustainable fuels are available at scale.

However, if Germany follows the slower pathway and reaches net-zero by 2045, it risks becoming reliant on gas as baseload power for much of the 2030s amid renewable expansion challenges that persist, potentially harming its ability to reach its climate goals. 

Creating the infrastructure to pivot to sustainable fuels is one of the greatest challenges facing the German system. The ability to convert existing capacity to run purely on hydrogen via hydrogen-ready power plants will be key to reaching net-zero by 2040 and unlocking the significant system-wide benefits on offer.

Jan Andersson, General Manager of Market Development in Germany, Wärtsilä Energy added: “To reach the 2040 target and unlock the greatest benefits, the most important thing that Germany can do is build renewables now. 19 GW is an ambitious target, but Germany can do it. History shows us that Germany has been able to achieve high levels of renewable buildout in previous years. It must now reach those levels consistently.

“Creating a clear plan which sets out the steps to net zero is essential. Renewable energy is inherently intermittent, so flexible energy capacity will play a vital role. While batteries provide effective short-term flexibility, gas is currently the only practical long-term option. If Germany is to unlock the greatest benefits from decarbonisation, it must have a clear plan to integrate sustainable fuel. From 2030, all new thermal capacity must run solely on hydrogen.”

Analysis of the last decade demonstrates that the rapid expansion of renewable energy is possible, and that renewables overtook coal and nuclear in generation. Previously, Germany has built large amounts of renewable capacity, including 8GW of solar PV in 2010 and 2011, 5.3 GW of onshore wind in 2017, and 2.5 GW of offshore wind in 2015.

The significant reductions in the cost of electricity demonstrated in the modelling are driven by the fact that renewables are far cheaper to run than coal or gas plants, even as coal still provides about a third of electricity in Germany. The initial capital investment is far outweighed by the ongoing operational expense of fossil fuel-based power.

As well as reducing emissions and costs, Germany’s rapid path to net-zero can also unlock a series of additional benefits. If coal is phased out by 2030 but capacity is not replaced by high levels of renewable energy, Germany risks becoming a significant energy importer, peaking at 162 TWh in 2035. The accelerated pathway would reduce imports by a third.

Likewise, more renewable energy will help to electrify district heating, meaning Germany can move away from carbon-intensive fuels sooner. If Germany follows the accelerated path, 57% of Germany’s heating could be electrified in 2045, compared to 10% under the slower plan.

Jan Andersson concluded: “The opportunities on offer are vast. Germany can provide the blueprint for net zero and galvanise an entire continent. Now is the time for the new government to seize the initiative.”

How utilities are using AI to adapt to electricity demands

AI Load Forecasting for Utilities leverages machine learning, smart meters, and predictive analytics to balance energy demand during COVID-19 disruptions, optimize grid reliability, support demand response, and stabilize rates for residential and commercial customers.

 

Key Points

AI predicts utility demand with ML and smart meters to improve reliability and reduce costs.

✅ Adapts to rapid demand shifts with accurate short term forecasts

✅ Optimizes demand response and distributed energy resources

✅ Reduces outages risk while lowering procurement and operating costs

 

The spread of the novel coronavirus that causes COVID-19 has prompted state and local governments around the U.S. to institute shelter-in-place orders and business closures. As millions suddenly find themselves confined to their homes, the shift has strained not only internet service providers, streaming platforms, and online retailers, but the utilities supplying power to the nation’s electrical grid, which face longer, more frequent outages as well.

U.S. electricity use on March 27, 2020 was 3% lower than it was on March 27, 2019, a loss of about three years of sales growth. Peter Fox-Penner, director of the Boston University Institute for Sustainable Energy, asserted in a recent op-ed that utility revenues will suffer because providers are halting shutoffs and deferring rate increases. Moreover, according to research firm Wood Mackenzie, the rise in household electricity demand won’t offset reduced business electricity demand, mainly because residential demand makes up just 40% of the total demand across North America.

Some utilities are employing AI and machine learning for the energy transition to address the windfalls and fluctuations in energy usage resulting from COVID-19. Precise load forecasting could ensure that operations aren’t interrupted in the coming months, thereby preventing blackouts and brownouts. And they might also bolster the efficiency of utilities’ internal processes, leading to reduced prices and improved service long after the pandemic ends.

Innowatts
Innowatts, a startup developing an automated toolkit for energy monitoring and management, counts several major U.S. utility companies among its customers, including Portland General Electric, Gexa Energy, Avangrid, Arizona Public Service Electric, WGL, and Mega Energy. Its eUtility platform ingests data from over 34 million smart energy meters across 21 million customers in more than 13 regional energy markets, while its machine learning algorithms analyze the data to forecast short- and long-term loads, variances, weather sensitivity, and more.

Beyond these table-stakes predictions, Innowatts helps evaluate the effects of different rate configurations by mapping utilities’ rate structures against disaggregated cost models. It also produces cost curves for each customer that reveal the margin impacts on the wider business, and it validates the yield of products and cost of customer acquisition with models that learn the relationships between marketing efforts and customer behaviors (like real-time load).

Innowwatts told VentureBeat that it observed “dramatic” shifts in energy usage between the first and fourth weeks of March. In the Northeast, “non-essential” retailers like salons, clothing shops, and dry cleaners were using only 35% as much energy toward the end of the month (after shelter-in-place orders were enacted) versus the beginning of the month, while restaurants (excepting pizza chains) were using only 28%. In Texas, conversely, storage facilities were using 142% as much energy in the fourth week compared with the first.

Innowatts says that throughout these usage surges and declines, its clients took advantage of AI-based load forecasting to learn from short-term shocks and make timely adjustments. Within three days of shelter-in-place orders, the company said, its forecasting models were able to learn new consumption patterns and produce accurate forecasts, accounting for real-time changes.

Innowatts CEO Sid Sachdeva believes that if utility companies had not leveraged machine learning models, demand forecasts in mid-March would have seen variances of 10-20%, significantly impacting operations.

“During these turbulent times, AI-based load forecasting gives energy providers the ability to … develop informed, data-driven strategies for future success,” Sachdeva told VentureBeat. “With utilities and energy retailers seeing a once-in-a-lifetime 30%-plus drop in commercial energy consumption, accurate forecasting has never been more important. Without AI tools, utilities would see their forecasts swing wildly, leading to inaccuracies of 20% or more, placing an enormous strain on their operations and ultimately driving up costs for businesses and consumers.”

Autogrid
Autogrid works with over 50 customers in 10 countries — including Energy Australia, Florida Power & Light, and Southern California Edison — to deliver AI-informed power usage insights. Its platform makes 10 million predictions every 10 minutes and optimizes over 50 megawatts of power, which is enough to supply the average suburb.

Flex, the company’s flagship product, predicts and controls tens of thousands of energy resources from millions of customers by ingesting, storing, and managing petabytes of data from trillions of endpoints. Using a combination of data science, machine learning, and network optimization algorithms, Flex models both physics and customer behavior, automatically anticipating and adjusting for supply and demand patterns through virtual power plants that coordinate distributed assets.

Autogrid also offers a fully managed solution for integrating and utilizing end-customer installations of grid batteries and microgrids. Like Flex, it automatically aggregates, forecasts, and optimizes capacity from assets at sub-stations and transformers, reacting to distribution management needs while providing capacity to avoid capital investments in system upgrades.

Autogrid CEO Dr. Amit Narayan told VentureBeat that the COVID-19 crisis has heavily shifted daily power distribution in California, where it’s having a “significant” downward impact on hourly prices in the energy market. He says that Autogrid has also heard from customers about transformer failures in some regions due to overloaded circuits, which he expects will become a problem in heavily residential and saturated load areas during the summer months (as utilities prepare for blackouts across the U.S. when air conditioning usage goes up).

“In California, [as you’ll recall], more than a million residents faced wildfire prevention-related outages in PG&E territory in 2019,” Narayan said, referring to the controversial planned outages orchestrated by Pacific Gas & Electric last summer. “The demand continues to be high in 2020 in spite of the COVID-19 crisis, as residents prepare to keep the lights on and brace for a similar situation this summer. If a 2019 repeat happens again, it will be even more devastating, given the health crisis and difficulty in buying groceries.”

AI making a difference
AI and machine learning isn’t a silver bullet for the power grid — even with predictive tools at their disposal, utilities are beholden to a tumultuous demand curve and to mounting climate risks across the grid. But providers say they see evidence the tools are already helping to prevent the worst of the pandemic’s effects — chiefly by enabling them to better adjust to shifted daily and weekly power load profiles.

“The societal impact [of the pandemic] will continue to be felt — people may continue working remotely instead of going into the office, they may alter their commute times to avoid rush hour crowds, or may look to alternative modes of transportation,” Schneider Electric chief innovation officer Emmanuel Lagarrigue told VentureBeat. “All of this will impact the daily load curve, and that is where AI and automation can help us with maintenance, performance, and diagnostics within our homes, buildings, and in the grid.”

Gov. Greg Abbott touts Texas power grid's readiness heading into fall, election season

ERCOT Texas Fall Grid Forecast outlines ample power supply, planned maintenance outages, and grid reliability, citing PUC oversight and Gov. Abbott's remarks, with seasonal assessment noting mild demand yet climate risks and conservation alerts.

 

Key Points

ERCOT's seasonal outlook for Texas on fall power supply, outages, and reliability expectations under PUC oversight.

✅ Projects sufficient supply in October and November

✅ Many plants scheduled offline for maintenance

✅ Notes PUC oversight and Abbott's confidence

 

Gov. Greg Abbott said Tuesday that the Texas power grid is prepared for the fall months and referenced a new seasonal forecast by the state’s grid operator, which typically does not draw much attention to its fall and spring grid assessments because of the more mild temperatures during those seasons.

Tuesday’s new forecast by the Electric Reliability Council of Texas showed that there should be plenty of power supply to meet demand in October and November. It also showed that many Texas power plants are scheduled to be offline this fall for maintenance work. Texas power plants usually plan to go down in the fall and spring for repairs to improve reliability ahead of the more extreme temperatures in winter and summer, when Texans crank up their heat and air conditioning and raise demand for power.

ERCOT for at least a decade announced its seasonal forecasts, but did not do so on Tuesday. The grid operator stopped announcing the reports after the 2021 winter storm event. A spokesperson for the grid operator, which posted the report to its website midday without notifying the public or power industry stakeholders, said there were no plans to discuss the latest forecast and referred questions about it to the Public Utility Commission, which oversees ERCOT. Abbott appoints the board of the PUC.

Abbott on Tuesday expressed his confidence about the grid in a news release, which included photos of the governor sitting at a table with incoming ERCOT CEO Pablo Vegas, outgoing interim CEO Brad Jones and Public Utility Commission Chair Peter Lake.

“The State of Texas continues to monitor the reliability of our electric grid, and I thank ERCOT and PUC for their hard work to implement bipartisan reforms we passed last year and for their proactive leadership to ensure our grid is stronger than ever before,” Abbott said in the release.

Abbott has not previously shared or called attention to ERCOT’s forecasts as he did on Tuesday.

Up for reelection this fall, Abbott has faced continued criticism, including from the Sierra Club over his handling of the 2021 deadly power grid disaster, when extended freezing temperatures shut down natural gas facilities and power plants, which rely on each other to keep electricity flowing. The resulting blackouts left millions of Texans without power for days in the cold, and hundreds of people died.

ERCOT’s forecasts for fall and spring are typically the least worrisome seasonal forecasts, energy experts said, because temperatures are usually milder in between summer and winter, even as ERCOT has issued an RFP to procure winter capacity to address shortages, so demand for power usually does not skyrocket like it does during extreme temperatures.

But they’ve warned that climate change could potentially lead to more extreme temperatures during times when Texas hasn’t experienced such weather in the past. For example, in early May six power plants unexpectedly broke down when a spring heat wave drove power demand up and highlighted broader heat-related blackout risks across the grid. ERCOT asked Texans to conserve electricity at home at the time.

Abbott released the seasonal report at a time when he has asserted unprecedented control over ERCOT. Although he had no formal role in ERCOT’s search for a new permanent CEO, he put a stranglehold on the process, The Texas Tribune previously reported. Since the winter storm, Abbott’s office has also dictated what information about the power grid ERCOT has released to the public.

California's solar energy gains go up in wildfire smoke

California Wildfire Smoke Impact on Solar reduces photovoltaic output, as particulate pollution, soot, and haze dim sunlight and foul panels, cutting utility-scale generation and grid reliability across CAISO during peak demand and heatwaves.

 

Key Points

How smoke and soot cut solar irradiance and foul panels, slashing PV generation and straining CAISO grid operations.

✅ Smoke blocks sunlight; soot deposition reduces panel efficiency.

✅ CAISO reported ~30% drop versus July during peak smoke.

✅ Longer fire seasons threaten solar reliability and capacity planning.

 

Smoke from California’s unprecedented wildfires was so bad that it cut a significant chunk of solar power production in the state, even as U.S. solar generation rose in 2022 nationwide. Solar power generation dropped off by nearly a third in early September as wildfires darkened the skies with smoke, according to the US Energy Information Administration.

Those fires create thick smoke, laden with particles that block sunlight both when they’re in the air and when they settle onto solar panels. In the first two weeks of September, soot and smoke caused solar-powered electricity generation to fall 30 percent compared to the July average, according to the California Independent System Operator (CAISO), which oversees nearly all utility-scale solar energy in California, where wind and solar curtailments have been rising amid grid constraints. It was a 13.4 percent decrease from the same period last year, even though solar capacity in the state has grown about 5 percent since September 2019.

California depends on solar installations for nearly 20 percent of its electricity generation, and has more solar capacity than the next five US states trailing it combined as it works to manage its solar boom sustainably. It will need even more renewable power to meet its goal of 100 percent clean electricity generation by 2045, building on a recent near-100% renewable milestone that underscored the transition. The state’s emphasis on solar power is part of its long-term efforts to avoid more devastating effects of climate change. But in the short term, California’s renewables are already grappling with rising temperatures.

Two records were smashed early this September that contributed to the loss of solar power. California surpassed 2 million acres burned in a single fire season for the first time (1.7 million more acres have burned since then). And on September 15th, small particle pollution reached the highest levels recorded since 2000, according to the California Air Resources Board. Winds that stoked the flames also drove pollution from the largest fires in Northern California to Southern California, where there are more solar farms.

Smaller residential and commercial solar systems were affected, too, and solar panels during grid blackouts typically shut off for safety, although smoke was the primary issue here. “A lot of my systems were producing zero power,” Steve Pariani, founder of the solar installation company Solar Pro Energy Systems, told the San Mateo Daily Journal in September.

As the planet heats up, California’s fire seasons have grown longer, and blazes are tearing through more land than ever before, while grid operators are also seeing rising curtailments as they integrate more renewables. For both utilities and smaller solar efforts, wildfire smoke will continue to darken solar energy’s otherwise bright future, even as it becomes the No. 3 renewable source in the U.S. by generation.

RBC agrees to buy electricity from new southern Alberta solar power farm project

RBC Renewable Energy PPA supports a 39 MW Alberta solar project, with Bullfrog Power and BluEarth Renewables, advancing clean energy in a deregulated market through a long-term power purchase agreement in Canada today.

 

Key Points

A long-term power purchase agreement where RBC buys most output from a 39 MW Alberta solar project via Bullfrog Power.

✅ 39 MW solar build in County of Forty Mile, Alberta

✅ Majority of output purchased by RBC via Bullfrog Power

✅ Supports cost-competitive renewables in deregulated market

 

The Royal Bank of Canada says it is the first Canadian bank to sign a long-term renewable energy power purchase agreement, a deal that will support the development of a 39-megawatt, $70-million solar project in southern Alberta, within an energy powerhouse province.

The bank has agreed with green energy retailer Bullfrog Power to buy the majority of the electricity produced by the project, as a recent federal green electricity contract highlights growing demand, to be designed and built by BluEarth Renewables of Calgary.

The project is to provide enough power for over 6,400 homes and the panel installations will cover 120 hectares, amid a provincial renewable energy surge that could create thousands of jobs, the size of 170 soccer fields.

The solar installation is to be built in the County of Forty Mile, a hot spot for renewable power that was also chosen by Suncor Energy Inc. for its $300-million 200-MW wind power project (approved last year and then put on hold during the COVID-19 pandemic), and home to another planned wind power farm in Alberta.

BluEarth says commercial operations at its Burdett and Yellow Lake Solar Project are expected to start up in April 2021, underscoring solar power growth in the province.

It says the agreement shows that renewable energy can be cost-competitive, with lower-cost solar contracts in a deregulated electricity market like Alberta’s, adding the province has some of the best solar and wind resources in Canada.

“We’re proud to be the first Canadian bank to sign a long-term renewable energy power purchase agreement, demonstrating our commitment to clean, sustainable power, as Alberta explores selling renewable energy at scale,” said Scott Foster, senior vice-president and global head of corporate real estate at RBC.
