Covid-19 puts brake on Turkey’s solar sector

Alberta wind power surpasses coal as AESO reports record renewable energy feeding the grid, with natural gas conversions, solar growth, energy storage, and decarbonization momentum lowering carbon intensity across Alberta's electricity system.

Key Points

AESO data shows wind surpassing coal in Alberta, driven by coal retirements, gas conversions, and growing renewables.

✅ AESO reports wind output above coal several times this week

✅ Coal units retire or convert to natural gas, boosting renewables

✅ Carbon intensity falls; storage and solar improve grid reliability

Marking a significant shift in Alberta energy history, wind generation trends provided more power to the province's energy grid than coal several times this week.

According to data from the Alberta Energy System Operator (AESO) released this week, wind generation units contributed more energy to the grid than coal at times for several days. On Friday afternoon, wind farms contributed more than 1,700 megawatts of power to the grid, compared to around 1,260 megawatts from coal stations.

"The grid is going through a period of transformative change when we look at the generation fleet, specifically as it relates to the coal assets in the province," Mike Deising, AESO spokesperson, told CTV News in an interview.

The shift in electricity generation comes as more coal plants come offline in Alberta, or transition to cleaner energy through natural gas generation, including the last of TransAlta's units at the Keephills Plant west of Edmonton.

Only three coal generation stations remain online in the province, at the Genesee plant southwest of Edmonton, as the coal phase-out timeline advances. Less available coal power, means renewable energy like wind and solar make up a greater portion of the grid.

EVOLUTION OF THE GRID
"Our grid is changing, and it's evolving," Deising said, adding that more units have converted to natural gas and companies are making significant investments into solar and wind energy.

For energy analyst Kevin Birn with IHS Markit, that trend is only going to continue.

"What we've seen for the last 24 to 36 months is a dramatic acceleration in ambition, policy, and projects globally around cleaner forms of energy or lower carbon forms of energy," Birn said.

Birn, who is also chief analyst of Canadian Oil Markets, added that not only has the public appetite for cleaner energy helped fuel the shift, but technological advancements have made renewables like wind and solar more cost-efficient.

"Alberta was traditionally heavily coal-reliant," he said. "(Now) western Canada has quite a diverse energy base."

LESS CARBON-INTENSIVE
According to Birn, the shift in energy production marks a significant reduction in carbon emissions as Alberta progresses toward its last coal plant closure milestone.

Ten years ago, IHS Markit estimates that Alberta's grid contributed about 900 kilograms of carbon dioxide equivalent per megawatt-hour of energy generation.

"That (figure is) really representing the dominance and role of coal in that grid," Birn said.

Current estimates show that figure is closer to 600 kilograms of CO2 equivalent.

"That means the power you and I are using is less carbon-intensive," Birn said, adding that figure will continue to fall over the next couple of years.

RENEWABLES HERE TO STAY
While many debate whether Alberta's energy is getting clean enough fast enough, Birn believes change is coming.

"It's been a half-decade of incredible price volatility in the oil market which had really dominated this sector and region," the analyst said.

"When I think of the future, I see the power sector building on large-scale renewables, which means decarbonization, and that provides an opportunity for those tech companies looking for clean energy places to land facilities."

Coal and natural gas are considered baseline assets by the AESO, where generation capacity does not shift dramatically, though some utilities report declining coal returns in other markets.

"Wind is a variable resource. It will generate when the wind is blowing, and it obviously won't when the wind is not," Deising said. "Wind and solar can ramp quickly, but they can drop off quite quickly, and we have to be prepared.

"We factor that into our daily planning and assessments," he added. "We follow those trends and know where the renewables are going to show up on the system, how many renewables are going to show up."

Deising says one wind plant in Alberta currently has an energy storage capacity to preserve renewably generated electricity during summer demand records and peak hours as needed. As the technology becomes more affordable, he expects more plants to follow suit.

"As a system operator, our job is to make sure as (the grid) is evolving we can continue to provide reliable power to Albertans at every moment every day," Deising said. "We just have to watch the system more carefully."

OPG Pickering Nuclear Refurbishment extends four CANDU reactors to bolster Ontario clean energy, grid reliability, and decarbonization goals, leveraging Darlington lessons, mature supply chains, and AtkinsRealis OEM expertise for cost effective life extension.

Key Points

Modernizing four Pickering CANDU units to extend life, add clean power, and enhance Ontario grid reliability.

✅ Extends four 515 MW CANDU reactors by 30 years

✅ Supports clean, reliable baseload and decarbonization

✅ Leverages Darlington playbook and AtkinsRealis OEM supply chain

In a pivotal shift last month, Ontario Power Generation (OPG) revised its strategy for the Pickering Nuclear Power Station, scrapping plans to decommission its six remaining reactors. Instead, OPG has opted to modernize four reactors (Pickering B Units 5-8) starting in 2027, while Units 1 and 4 are slated for closure by the end of the current year.

This revision ensures the continued operation of the four 515 MW Canada Deuterium Uranium (CANDU) reactors—originally constructed in the 1970s and 1980s—extending their service life by at least 30 more years amid an extension request deadline for Pickering.

Todd Smith, Ontario's Energy Minister, underscored the significance of nuclear power in maintaining Ontario's status as a region with one of the cleanest and most reliable electricity grids globally. He emphasized the integral role of nuclear facilities, particularly the Pickering station, in the provincial energy strategy during the announcement supporting continued operations, which was made in the presence of union workers at the plant.

The Pickering station has demonstrated remarkable efficiency and reliability, notably achieving its second-highest output in 2023 and setting a record in 2022 for continuous operation. Extending the lifespan of nuclear plants like Pickering is deemed the most cost-effective method for sustaining low-carbon electricity, according to research conducted by the International Energy Agency (IEA) and the OECD Nuclear Energy Agency (NEA) across 243 plants in 24 countries.

The refurbishment project is poised to significantly boost Ontario's economy, projected to add CAN$19.4 billion to the GDP over 11 years and generate approximately 11,000 jobs annually. The Independent Electricity System Operator (IESO) has indicated that to meet the province's future electrification and decarbonization goals, as it faces a growing electricity supply gap, Ontario will need to double its nuclear capacity by 2050, requiring an addition of 17.8 GW of nuclear power.

Subo Sinnathamby, OPG's Senior Vice President of Nuclear Refurbishment, emphasized the necessity of nuclear energy in reducing reliance on natural gas. Sinnathamby, who is leading the refurbishment efforts at OPG's Darlington nuclear power station, where SMR plans are also underway, highlighted the positive impact of the Darlington and Bruce Power projects on the nuclear power supply chain and workforce.

The procurement strategy employed for Darlington, which involved placing orders early to ensure readiness among suppliers, is set to be replicated for the Pickering refurbishment. This approach aims to facilitate a seamless transition of skilled workers and resources from Darlington to Pickering refurbishment, leveraging a matured supply chain and experienced vendors.

AtkinsRealis, the original equipment manufacturer (OEM) for CANDU reactors, has a track record of successfully refurbishing CANDU plants worldwide. The CANDU reactor design, known for its refurbishment capabilities, allows for individual replacement of pressure tubes and access to fuel channels without decommissioning the reactor. Gary Rose, Executive Vice-President of Nuclear at AtkinsRealis, highlighted the economic benefits and environmental benefits of refurbishing reactors, stating it as a viable and swift solution to maximize fossil-free energy.

Looking forward, AtkinsRealis is exploring the potential for multiple refurbishments of CANDU reactors, which could extend their operational life beyond 100 years, addressing local energy needs and economic factors in the decision-making process. This innovative approach underscores the role of nuclear refurbishment in meeting global energy demands sustainably and economically.

OPG Small Modular Reactors advance clean energy with advanced nuclear, baseload power, renewables integration, and grid reliability; factory built, scalable, and cost effective to support Ontario energy security and net zero goals.

Key Points

Factory built nuclear units delivering reliable, low carbon power to support Ontario's grid, renewables, climate goals.

✅ Factory built modules cut costs and shorten schedules

✅ Provides baseload power to balance wind and solar

✅ Enhances grid reliability with advanced safety and waste reduction

Ontario Power Generation (OPG) is at the forefront of Canada’s energy transformation, demonstrating a robust commitment to sustainable energy solutions. One of the most promising avenues under exploration is the development of Small Modular Reactors (SMRs), as OPG broke ground on the first SMR at Darlington to launch this next phase. These innovative technologies represent a significant leap forward in the quest for reliable, clean, and cost-effective energy generation, aligning with Ontario’s ambitious climate goals and energy security needs.

Understanding Small Modular Reactors

Small Modular Reactors are advanced nuclear power plants that are designed to be smaller in size and capacity compared to traditional nuclear reactors. Typically generating up to 300 megawatts of electricity, SMRs can be constructed in factories and transported to their installation sites, offering flexibility and scalability that larger reactors do not provide. This modular approach reduces construction time and costs, making them an appealing option for meeting energy demands.

One of the key advantages of SMRs is their ability to provide baseload power—energy that is consistently available—while simultaneously supporting intermittent renewable sources like wind and solar. As Ontario continues to increase its reliance on renewables, SMRs could play a crucial role in ensuring that the energy supply remains stable and secure.

OPG’s Initiative

In its commitment to advancing clean energy technologies, OPG has been a strong advocate for the adoption of SMRs. The province of Ontario has announced plans to develop three additional small modular reactors, part of its plans for four Darlington SMRs that would further enhance the region’s energy portfolio. This initiative aligns with both provincial and federal climate objectives, and reflects a collaborative provincial push on nuclear innovation to accelerate clean energy.

The deployment of SMRs in Ontario is particularly strategic, given the province’s existing nuclear infrastructure, including the continued operation of Pickering NGS that supports grid reliability. OPG operates a significant portion of Ontario’s nuclear fleet, and leveraging this existing expertise can facilitate the integration of SMRs into the energy mix. By building on established operational frameworks, OPG can ensure that new reactors are deployed safely and efficiently.

Economic and Environmental Benefits

The introduction of SMRs is expected to bring substantial economic benefits to Ontario. The construction and operation of these reactors will create jobs, including work associated with the Pickering B refurbishment across the province, stimulate local economies, and foster innovation in nuclear technology. Additionally, SMRs have the potential to attract investment from both domestic and international stakeholders, positioning Ontario as a leader in advanced nuclear technology.

From an environmental perspective, SMRs are designed with enhanced safety features and lower waste production compared to traditional reactors, complementing life-extension measures at Pickering that bolster system reliability. They can significantly contribute to Ontario’s goal of achieving net-zero emissions by 2050. By providing a reliable source of clean energy, SMRs will help mitigate the impacts of climate change while supporting the province's transition to a sustainable energy future.

Community Engagement and Collaboration

Recognizing the importance of community acceptance and stakeholder engagement, OPG is committed to an open dialogue with local communities and Indigenous groups. This collaboration is essential to addressing concerns and ensuring that the deployment of SMRs is aligned with the values and priorities of the residents of Ontario. By fostering a transparent process, OPG aims to build trust and support for this innovative energy solution.

Moreover, the development of SMRs will involve partnerships with various stakeholders, including government agencies, research institutions, and private industry, such as the OPG-TVA partnership to advance new nuclear technology. These collaborations will not only enhance the technical aspects of SMR deployment but also ensure that Ontario can capitalize on shared expertise and resources.

Looking Ahead

As Ontario Power Generation moves forward with plans for three additional Small Modular Reactors, the province stands at a critical juncture in its energy evolution. The integration of SMRs into Ontario’s energy landscape promises a sustainable, reliable, and economically viable solution to meet growing energy demands while addressing climate change challenges.

With the support of government initiatives, community collaboration, and continued innovation in nuclear technology, Ontario is poised to become a leader in the advancement of Small Modular Reactors. The successful implementation of these projects could serve as a model for other jurisdictions seeking to transition to cleaner energy sources, highlighting the role of nuclear power in a balanced and sustainable energy future.

In conclusion, OPG's commitment to developing Small Modular Reactors not only reinforces Ontario’s energy security but also demonstrates a proactive approach to addressing the pressing challenges of climate change and environmental sustainability. The future of energy in Ontario looks promising, driven by innovation and a commitment to clean energy solutions.

Texas Electric Cooperatives outperformed during Winter Storm Uri, with higher customer satisfaction, equitable rolling blackouts, and stronger grid reliability compared to deregulated markets, according to ERCOT-area survey data of regulated utilities and commercial providers.

Key Points

Member-owned utilities in Texas delivering power, noted for reliability and fair outages during Winter Storm Uri.

✅ Member-owned, regulated utilities serving local communities

✅ Rated higher for blackout management and communication

✅ Operate outside deregulated markets; align incentives with users

Winter Storm Uri began to hit parts of Texas on February 13, 2021 and its onslaught left close to 4.5 million Texas homes and businesses without power, and many faced power and water disruptions at its peak. By some accounts, the preliminary number of deaths attributed to the storm is nearly 200, and the economic toll for the Lone Star State is estimated to be as high as $295 billion. 

The more than two-thirds of Texans who lost power during this devastating storm were notably more negative than positive in their evaluation of the performance of their local electric utility, mirrored by a rise in electricity complaints statewide, with one exception. That exception are the members of the more than 60 electric cooperatives operating within the Texas Interconnection electrical grid, which, in sharp contrast to the customers of the commercial utilities that provide power to the majority of Texans, gave their local utility a positive evaluation related to its performance during the storm.

In order to study Winter Storm Uri’s impact on Texas, the Hobby School of Public Affairs at the University of Houston conducted an online survey during the first half of March of residents 18 and older who live in the 213 counties (91.5% of the state population) served by the Texas power grid, which is managed by the Electric Reliability Council of Texas (ERCOT). 

Three-quarters of the survey population (75%) live in areas with a deregulated utility market, where a specified transmission and delivery utility by region is responsible for delivering the electricity (purchased from one of a myriad of private companies by the consumer) to homes and businesses. The four main utility providers are Oncor, CenterPoint CNP -2.2%, American Electric Power (AEP) North, and American Electric Power (AEP) Central. 

The other 25% of the survey population live in areas with regulated markets, where a single company is responsible for both delivering the electricity to homes and businesses and serves as the only source from which electricity is purchased. Municipal-owned and operated utilities (e.g., Austin Energy, Bryan Texas Utilities, Burnet Electric Department, Denton Municipal Electric, New Braunfels Utilities, San Antonio’s CPS Energy CMS -2.1%) serve 73% of the regulated market. Electric cooperatives (e.g., Bluebonnet Electric Cooperative, Central Texas Electric Cooperative, Guadalupe Valley Cooperative, Lamb County Electric Cooperative, Pedernales Electricity Cooperative, Wood County Electric Cooperative) serve one-fifth of this market (21%), with private companies accounting for 6% of the regulated market.

The overall distribution of the survey population by electric utility providers is: Oncor (38%), CenterPoint (21%), municipal-owned utilities (18%), AEP Central & AEP North combined (12%), electric cooperatives (6%), other providers in the deregulated market (4%) and other providers in the regulated market (1%). 

There were no noteworthy differences among the 31% of Texans who did not lose power during the winter storm in regard to their evaluations of their local electricity provider or their belief that the power cuts in their locale were carried out in an equitable manner.  

However, among the 69% of Texans who lost power, those served by electric cooperatives in the regulated market and those served by private electric utilities in the deregulated market differed notably regarding their evaluation of the performance of their local electric utility, both in regard to their management of the rolling blackouts, amid debates over market reforms to avoid blackouts, and to their overall performance during the winter storm. Those Texans who lost power and are served by electric cooperatives in a regulated market had a significantly more positive evaluation of the performance of their local electric utility than did those Texans who lost power and are served by a private company in a deregulated electricity market. 

For example, only 24% of Texans served by electric cooperatives had a negative evaluation of their local electric utility’s overall performance during the winter storm, compared to 55%, 56% and 61% of those served by AEP, Oncor and CenterPoint respectively. A slightly smaller proportion of Texans served by electric cooperatives (22%) had a negative evaluation of their local electric utility’s performance managing the rolling blackouts during the winter storm, compared to 58%, 61% and 71% of Texans served by Oncor, AEP and CenterPoint, respectively.

Texans served by electric cooperatives in regulated markets were more likely to agree that the power cuts in their local area were carried out in an equitable manner compared to Texans served by commercial electricity utilities in deregulated markets. More than half (52%) of those served by an electric cooperative agreed that power cuts during the winter storm in their area were carried out in an equitable manner, compared to only 26%, 23% and 23% of those served by Oncor, AEP and CenterPoint respectively

The survey data did not allow us to provide a conclusive explanation as to why the performance during the winter storm by electric cooperatives (and to a much lesser extent municipal utilities) in the regulated markets was viewed more favorably by their customers than was the performance of the private companies in the deregulated markets viewed by their customers. Yet here are three, far from exhaustive, possible explanations.

First, electric cooperatives might have performed better (based on objective empirical metrics) during the winter storm, perhaps because they are more committed to their customers, who are effectively their bosses. .  

Second, members of electric cooperatives may believe their electric utility prioritizes their interests more than do customers of commercial electric utilities and therefore, even if equal empirical performance were the case, are more likely to rate their electric utility in a positive manner than are customers of commercial utilities.  

Third, regulated electric utilities where a single entity is responsible for the commercialization, transmission and distribution of electricity might be better able to respond to the type of challenges presented by the February 2021 winter storm than are deregulated electric utilities where one entity is responsible for commercialization and another is responsible for transmission and distribution, aligning with calls to improve electricity reliability across Texas.

Other explanations for these findings may exist, which in addition to the three posited above, await future empirical verification via new and more comprehensive studies designed specifically to study electric cooperatives, large commercial utilities, and the incentives that these entities face under the regulatory system governing production, commercialization and distribution of electricity, including rulings that some plants are exempt from providing electricity in emergencies under state law. 

Still, opinion about electricity providers during Winter Storm Uri is clear: Texans served by regulated electricity markets, especially by electric cooperatives, were much more satisfied with their providers’ performance than were those in deregulated markets. Throughout its history, Texas has staunchly supported the free market. Could Winter Storm Uri change this propensity, or will attempts to regulate electricity lessen as the memories of the storm’s havoc fades? With a hotter summer predicted to be on the horizon in 2021 and growing awareness of severe heat blackout risks, we may soon get an answer.

California Heatwave Power Crisis strains CAISO as record demand triggers emergency alerts, demand response, and rolling blackout warnings. PG&E prepares outages while solar fades at peak, drought cuts hydropower, and reliability hinges on conservation.

Key Points

Extreme heat driving record demand in California, straining CAISO and prompting conservation to avert rolling blackouts.

✅ CAISO hit a record 52 GW peak load amid triple-digit heat

✅ Emergency alerts spurred demand response, cutting load spikes

✅ Solar drop and drought-weakened hydro worsened evening shortfall

California narrowly avoided blackouts for a second successive day even as blistering temperatures pushed electricity demand to a record and stretched the state’s power grid close to its limits.

The state imposed its highest level of energy emergency for several hours late Tuesday and urged consumers to turn off lights, curb air conditioners and shut off power-hungry appliances after a day of extraordinary stress on electricity infrastructure as temperatures in many regions topped 110 degrees Fahrenheit (43 Celsius).

Electricity use had reached 52 gigawatts Tuesday, easily breaking a record that stood since 2006, according to the California Independent System Operator. The state issued emergency alerts direct to cell phones in several counties asking for immediate power conservation, and grid data show that demand plunged in response. Emergency measures were finally lifted at about 9 p.m. local time.

Much of California remains under an excessive heat warning through Friday, with authorities already preparing for more severe pressure on the power system on Wednesday amid a looming supply shortage across the grid. “We aren’t out of the woods yet,” Governor Gavin Newsom said in a message posted on his office’s Twitter account. “We will see continued extreme temps this week and if we rallied today, we can do it again.”

The state’s largest power company, PG&E Corp. said earlier Tuesday that it had notified about 525,000 homes and businesses that they could lose power for up to two hours. That warning came as temperatures in downtown Sacramento hit 116 degrees Fahrenheit, topping a previous 1925 record.

Newsom earlier signed an executive order extending until Friday emergency measures to free up additional power supplies, rather than allowing them to expire as planned on Wednesday. Many state buildings were ordered to power down lights and air conditioning at 4 p.m., and he urged residents and businesses to conserve the equivalent of 3 gigawatts of power in order to stave off blackouts. 

California's Early Brush With Blackouts Bodes Ill For Days Ahead

California faced a similar energy emergency Monday, which was alleviated in part by activating temporary gas-fired power plants operated by the California Department of Water Resources. The current heat wave, which began in the last week of August, is remarkable in both its ferocity and duration, according to officials. 

The prospect of outages underscores how grids have become vulnerable in the face of extreme weather as California transitions from fossil fuels to renewable energy, an approach it is increasingly exporting to Western states as well. California's climate policies have aggressively closed natural-gas power plants in recent years, leaving the state increasingly dependent on solar farms that go dark late in the day just as electricity demand peaks. At the same time, the state is enduring the Southwest’s worst drought in 1,200 years, sapping hydropower production.

The average 15-minute wholesale power price in Caiso surged to $1,806 a megawatt-hour at 4:45 p.m. local time, according to the grid operator’s website.

Average day-ahead prices top $300 a megawatt-hour in Southern California
  
A break from the heat will come across Southern California later this week, thanks to Tropical Storm Kay in the Pacific Ocean, according to weather officials. Kay is forecast to edge up the coastline of Mexico’s Baja California peninsula. As it moves north, the storm will pump moisture and clouds into Southern California and Arizona, taking an edge off the heat.

Manitoba Hydro Debt Load surges past $19.2B as the Crown corporation faces shrinking net income, restructuring costs, and PUB rate decisions, driven by Bipole III, Keeyask construction, aging infrastructure, and rising interest rate risks.

Key Points

Manitoba Hydro Debt Load refers to the utility's escalating borrowings exceeding $19B, pressuring rates and finances.

✅ Debt rose to $19.2B; projected near $25B within five years.

✅ Major drivers: Bipole III, Keeyask, aging assets, restructuring.

✅ Rate hikes sought; PUB approved 3.6% vs 7.9% request.

Manitoba Hydro's debt load now exceeds $19 billion as the provincial Crown corporation grapples with a shrinking net income amid ongoing efforts to slay costs.

The utility's annual report, to be released publicly on Tuesday, also shows its total consolidated net income slumped from $71 million in 2016-2017 to $37 million in the last fiscal year, mirroring a Hydro One profit drop as electricity revenue fell.

It said efforts to restructure the utility and reduce costs are partly to blame for the $34 million drop in year-over-year income.

These earnings come nowhere close, however, to alleviating Hydro's long-term debt problem, a dynamic also seen in a BC Hydro deferred costs report about customer exposure. The figure is pegged at $19.2 billion this fiscal year, up from $16.1 billion the previous year and $14.2 billion in 2016.

The utility projects its debt will grow to about $25 billion in the next five years. Its largest expenses include finishing the Bipole III line, working on the Keeyask Generating System that is halfway done and rebuilding aging wood poles and substations, the report said.

"This level of debt increases the potential financial exposure from risks facing the corporation and is a concern for both

the corporation and our customers who may be exposed to higher rate increases in the event of rising interest rates, a prolonged drought or a major system failure," outgoing president and CEO Kelvin Shepherd wrote.

The income drop is primarily a result of the $50 million spent in the form of restructuring charges associated with the utility's efforts to streamline the organization and drive down costs, amid NDP criticism of Hydro changes related to government policy.

Those efforts included the implementation of buyouts for employees through what the utility dubbed its "voluntary departure program."

Among the changes, Manitoba Hydro reduced its workforce by 800 employees, which is expected to save the utility over $90 million per year. It also reduced its management positions by 26 per cent, a Monday news release said, while Hydro One leadership upheaval in Ontario drove its shares down during comparable governance turmoil.

To improve its financial situation, Hydro has applied for rate increases, even as the Consumers Coalition pushes to have the proposal rejected. The Public Utilities Board offered a 3.6 per cent average rate hike, instead of the 7.9 per cent jump the utility asked for.

In May, when the PUB rendered its decision, it made several recommendations as an alternative to raising rates, including receiving a share of carbon tax revenue and asking the government to help pay for Bipole III.

Hydro is projecting a net income of $70 million for 2018-2019, which includes the impact of the recent rate increase. That total reflects an approximately 20 per cent reduction in net income from 2017-18 after restructuring costs are calculated.
