NEW Hydro One shares down after Ontario government says CEO, board out

Hydro One Leadership Shakeup unsettles investors as Ontario government ousts CEO and board, pressuring shares; analysts cite political and regulatory risk, stock volatility, trimmed price targets, and dividend stability at the regulated utility.

 

Key Points

An abrupt CEO exit and board overhaul at Hydro One, driving share declines and raising political and regulatory risk.

✅ Shares fall as CEO retires and board resigns under provincial pressure.

✅ Analysts cut price targets; warn of political, regulatory risks.

✅ New board to pick CEO; province consults on compensation.

 

Hydro One Ltd. shares slid Thursday with some analysts sounding warnings of greater uncertainty after the new Ontario government announced the retirement of the electrical utility's chief executive and the replacement of its board of directors.

 After sagging by almost eight per cent in early trading on the Toronto Stock Exchange, following news that Q2 profit plunged 23% amid weaker electricity revenue, shares of the company were later down four per cent, or 81 cents, at $19.36 as of 11:42 a.m. ET.

On Wednesday, after stock markets had closed for the day, Ontario Premier Doug Ford announced the immediate retirement of Hydro One CEO Mayo Schmidt. He leaves with a $400,000 payout in lieu of post-retirement benefits and allowances, Hydro One said.

Doug Ford's government forces out Hydro One '$6-million man'

During the recent provincial election campaign, Ford vowed to fire Schmidt, who earned $6.2 million last year and whose salary wouldn't be reduced despite calls to cut electricity costs.

Paul Dobson, Hydro One's chief financial officer, will serve as acting CEO until a new top executive is selected.

Ford also said the entire board of directors of the utility would resign. Hydro One said a new board — four members of which will be nominated by the province — will select the company's next CEO, and the province will be consulted on the next leader's compensation.

A new board is expected to be formed by mid-August.

The provincial government is the largest single investor in Hydro One, holding a 47 per cent stake. The company was partly privatized by the former Liberal government in 2015, while the NDP has proposed to make hydro public again in Ontario to change course.

 

Doug Ford promises to keep Pickering nuclear plant open until 2024

In response to the government's move to supplant the utility's board and CEO, some analysts cautioned investors about too many unknowns in the near-term outlook, citing raised political or regulatory risks.

Analyst Jeremy Rosenfield of iA Securities cut his rating on Hydro One shares to hold from buy, and reduced his 12-month price target for the stock to $24 from $26.

Rosenfield said the stock is still a defensive investment supported by stable earnings and cash flows, good earnings growth and healthy dividend.

However, he said in a research note that "the heightened potential for further political interference in the province's electricity market and regulated utility framework represent key risk factors that are likely to outweigh Hydro One's fundamentals over the near term."

 

Potential challenge to find new CEO

Laurentian Bank Securities analyst Mona Nazir said in a research note that the magnitude of change all at once was "surprising but not shocking."

She said the agreement that will see Hydro One consult with the provincial government on matters involving executive pay could have an impact on the hiring of a new CEO for the utility.

"Given the government's open and public criticism of the company and a potential ceiling on compensation, it may be challenging to attract top talent to the position," she wrote.

Laurentian cut its rating on the Hydro One to hold and reduced its price target to $21 from $24.

Analysts at CIBC World Markets said investors face an uncertain future, noting parallels with debates at Manitoba Hydro over political direction.

"In particular, we are are concerned about the government meddling in with [power] rates," wrote Robert Catellier and Archit Kshetrapal in a research note, adding they believe the new provincial government is aiming for a 12 per cent reduction in customers' power bills.

CIBC reduced its price target on Hydro One's shares to $20.50 from its previous target of $24.

Rooftop Solar Grids

Rooftop solar grids transform urban infrastructure with distributed generation, photovoltaic panels, smart grid integration and energy storage, cutting greenhouse gas emissions, lowering utility costs, enabling net metering and community solar for low-carbon energy systems.

 

Key Points

Rooftop solar grids are PV systems on buildings that generate power, cut emissions, and enable smart grid integration.

✅ Lowers utility bills via net metering and demand offset

✅ Reduces greenhouse gases and urban air pollution

✅ Enables resiliency with storage, smart inverters, and microgrids

 

As urban areas expand and the climate crisis intensifies, cities are seeking innovative ways to integrate renewable energy sources into their infrastructure. One such solution gaining traction is the installation of rooftop solar grids. A recent CBC News article highlights the significant impact of these solar systems on urban environments, showcasing their benefits and the challenges they present.

Harnessing Unused Space for Sustainable Energy

Rooftop solar panels are revolutionizing how cities approach energy consumption and environmental sustainability. By utilizing the often-overlooked space on rooftops, these systems provide a practical solution for generating renewable energy in densely populated areas. The CBC article emphasizes that this approach not only makes efficient use of available space but also contributes to reducing a city's reliance on non-renewable energy sources.

The ability to generate clean energy directly from buildings helps decrease greenhouse gas emissions and, as scientists work to improve solar and wind power, promotes a shift towards a more sustainable energy model. Solar panels absorb sunlight and convert it into electricity, reducing the need for fossil fuels and lowering overall carbon footprints. This transition is crucial as cities grapple with rising temperatures and air pollution.

Economic and Environmental Advantages

The economic benefits of rooftop solar grids are considerable. For homeowners and businesses, installing solar panels can lead to substantial savings on electricity bills. The initial investment in solar technology is often balanced by long-term energy savings and financial incentives, such as tax credits or rebates, and evidence that solar is cheaper than grid electricity in Chinese cities further illustrates the trend toward affordability. According to the CBC report, these financial benefits make solar energy a compelling option for many urban residents and enterprises.

Environmentally, the advantages are equally compelling. Solar energy is a renewable and clean resource, and increasing the number of rooftop solar installations can play a pivotal role in meeting local and national renewable energy targets, as illustrated when New York met its solar goals early in a recent milestone. The reduction in greenhouse gas emissions from fossil fuel energy sources directly contributes to mitigating climate change and improving air quality.

Challenges in Widespread Adoption

Despite the clear benefits, the adoption of rooftop solar grids is not without its challenges. One of the primary hurdles is the upfront cost of installation. While prices for solar panels have decreased over time, the initial financial outlay remains a barrier for some property owners, and regions like Alberta have faced solar expansion challenges that highlight these constraints. Additionally, the effectiveness of solar panels can vary based on factors such as geographic location, roof orientation, and local weather patterns.

The CBC article also highlights the importance of supportive infrastructure and policies for the success of rooftop solar grids. Cities need to invest in modernizing their energy grids to accommodate the influx of solar-generated electricity, and, in the U.S., record clean energy purchases by Southeast cities have signaled growing institutional demand. Furthermore, policies and regulations must support solar adoption, including issues related to net metering, which allows solar panel owners to sell excess energy back to the grid.

Innovative Solutions and Future Prospects

The future of rooftop solar grids looks promising, thanks to ongoing technological advancements. Innovations in photovoltaic cells and energy storage solutions are expected to enhance the efficiency and affordability of solar systems. The development of smart grid technology and advanced energy management systems, including peer-to-peer energy sharing, will also play a critical role in integrating solar power into urban infrastructures.

The CBC report also mentions the rise of community solar projects as a significant development. These projects allow multiple households or businesses to share a single solar installation, making solar energy more accessible to those who may not have suitable rooftops for solar panels. This model expands the reach of solar technology and fosters greater community engagement in renewable energy initiatives.

Conclusion

Rooftop solar grids are emerging as a key element in the transition to sustainable urban energy systems. By leveraging unused rooftop space, cities can harness clean, renewable energy, reduce greenhouse gas emissions, and, as developers learn that more energy sources make better projects, achieve long-term economic savings. While there are challenges to overcome, such as initial costs and regulatory hurdles, the benefits of rooftop solar grids make them a crucial component of the future energy landscape. As technology advances and policies evolve, rooftop solar grids will play an increasingly vital role in shaping greener, more resilient urban environments.

Customers on the hook for $5.5 billion in deferred BC Hydro operating costs: report

BC Hydro Deferred Regulatory Assets detail $5.5 billion in costs under rate-regulated accounting, to be recovered from ratepayers, highlighting B.C. Utilities Commission oversight, audit scrutiny, financial reporting impacts, and public utility governance.

 

Key Points

BC Hydro defers costs as regulatory assets to recover from ratepayers, influencing rates and financial reporting.

✅ $5.5B in deferred costs recorded as net regulatory assets

✅ Rate impacts tied to B.C. Utilities Commission oversight

✅ Auditor General to assess accounting and governance

 

Auditor General Carol Bellringer says BC Hydro has deferred $5.5 billion in expenses that it plans to recover from ratepayers in the future, as rates to rise by 3.75% over two years.

Bellringer focuses on the deferred expenses in a report on the public utility's use of rate-regulated accounting to control electricity rates for customers.

"As of March 31, 2018, BC Hydro reported a total net regulatory asset of $5.455 billion, which is what ratepayers owe," says the report. "BC Hydro expects to recover this from ratepayers in the future. For BC Hydro, this is an asset. For ratepayers, this is a debt."

She says rate-regulated accounting is used widely across North America, but cautions that Hydro has largely overridden the role of the independent B.C. Utilities Commission to regulate rates.

"We think it's important for the people of B.C. and our members of the legislative assembly to better understand rate-regulated accounting in order to appreciate the impact it has on the bottom line for BC Hydro, for government as a whole, for ratepayers and for taxpayers, especially following a three per cent rate increase in April 2018," Bellringer said in a conference call with reporters.

Last June, the B.C. government launched a two-phase review of BC Hydro to find cost savings and look at the direction of the Crown utility, amid calls for change from advocates.

The review came shortly after a planned government rate freeze was overturned by the utilities commission, which resulted in a three per cent rate increase in April 2018.

A statement by BC Hydro and the government says a key objective of the review due this month is to enhance the regulatory oversight of the commission.

Bellringer's office will become BC Hydro's auditor next year — and will be assessing the impact of regulation on the utility's financial reporting.

"It is a complex area and confidence in the regulatory system is critical to protect the public interest," wrote Bellringer.

End of an Era: UK's Last Coal Power Station Goes Offline

UK Coal-Free Energy Transition highlights the West Burton A closure, accelerating renewable energy, wind, solar, nuclear, energy storage, smart grid upgrades, decarbonization, and net-zero goals while ensuring reliability, affordability, and a just transition for workers.

 

Key Points

A nationwide shift from coal power to renewables, storage, and nuclear to meet net-zero while maintaining reliability.

✅ West Burton A closure ends UK coal-fired generation

✅ Wind, solar, nuclear, storage strengthen grid resilience

✅ Government backs a just transition and worker retraining

 

The United Kingdom marks a historic turning point in its energy transition with the closure of the West Burton A Power Station in Nottinghamshire. This coal-fired power plant, once a symbol of the nation's industrial might, has now delivered its final watts of electricity to the grid, signalling the end of coal power generation in the UK.


A Landmark Shift Towards Clean Energy

The closure of West Burton A reflects a dramatic shift in the UK's energy landscape. Coal, the backbone of the UK's power generation for decades, is being phased out in favour of renewable energy sources like wind, solar, and nuclear. This transition aligns with the UK's ambitious net-zero emissions target, which aims to radically decarbonize the country's economy by 2050, though progress can falter, as when low-carbon generation stalled in 2019 amid changing market conditions.


Changing Energy Landscape

In the past, coal-fired power plants provided reliable, on-demand power. However, growing awareness of their significant environmental impact, particularly their contribution to climate change,  has accelerated the move away from coal. The UK government has set clear targets for eliminating coal power generation, and the industry has seen a steady decline as the share of coal fell to record lows in the electricity system.


Renewables Fill the Gap

The remarkable growth of renewable energy sources has enabled the transition away from coal. Wind and solar power, in particular, have experienced rapid development and falling costs, and in 2016 wind generated more electricity than coal for the first time. The UK now boasts substantial offshore and onshore wind farms and extensive solar installations. Additionally, investments in nuclear power and emerging energy storage technologies are increasing the reliability and diversity of the UK's power grid.


Economic and Social Impacts

The closure of the last coal-fired power station carries both economic and social impacts. While this change represents a victory for environmentalists, marked by milestones like a full week without coal power in Britain, the end of coal mining and power generation will lead to job losses in communities traditionally reliant on these industries.  The government has committed to supporting affected regions and facilitating a "just transition" for workers by retraining and creating new opportunities in the clean energy sector.


Global Implications

The UK's commitment to a coal-free future serves as a powerful example for other nations seeking to decarbonize their energy systems, including peers where Alberta's last coal plant closed recently. The nation's experience demonstrates that a transition to renewable energy sources is both possible and necessary. However, it also highlights the importance of careful planning and addressing the social and economic impacts of such a rapid energy revolution.


The Road Ahead

While the closure of West Burton A Power Station marks a historic milestone, the UK's transition to clean energy is far from complete. Maintaining a reliable and affordable energy supply, even as coal-free power records raise questions about energy bills, will require continued investment in renewable energy sources, energy storage, and advanced grid technologies.

Cheap material converts heat to electricity

Polycrystalline Tin Selenide Thermoelectrics enable waste heat recovery with ZT 3.1, matching single crystals while cutting costs, powering greener car engines, industrial furnaces, and thermoelectric generators via p-type and emerging n-type designs.

 

Key Points

Low-cost tin selenide devices that turn waste heat into power, achieving ZT 3.1 and enabling p-type and n-type modules.

✅ Oxygen removal prevents heat-leaking tin oxide grain skins.

✅ Polycrystalline ingots match single-crystal ZT 3.1 at lower cost.

✅ N-type tin selenide in development to pair with p-type.

 

So-called thermoelectric generators turn waste heat into electricity without producing greenhouse gas emissions, providing what seems like a free lunch. But despite helping power the Mars rovers, the high cost of these devices has prevented their widespread use. Now, researchers have found a way to make cheap thermoelectrics that work just as well as the pricey kind. The work could pave the way for a new generation of greener car engines, industrial furnaces, and other energy-generating devices.

“This looks like a very smart way to realize high performance,” says Li-Dong Zhao, a materials scientist at Beihang University who was not involved with the work. He notes there are still a few more steps to take before these materials can become high-performing thermoelectric generators. However, he says, “I think this will be used in the not too far future.”

Thermoelectrics are semiconductor devices placed on a hot surface, like a gas-powered car engine or on heat-generating electronics using thin-film converters to capture waste heat. That gives them a hot side and a cool side, away from the hot surface. They work by using the heat to push electrical charges from one to the other, a process of turning thermal energy into electricity that depends on the temperature gradient. If a device allows the hot side to warm up the cool side, the electricity stops flowing. A device’s success at preventing this, as well as its ability to conduct electrons, feeds into a score known as the figure of merit, or ZT.

 Over the past 2 decades, researchers have produced thermoelectric materials with increasing ZTs, while related advances such as nighttime solar cells have broadened thermal-to-electric concepts. The record came in 2014 when Mercouri Kanatzidis, a materials scientist at Northwestern University, and his colleagues came up with a single crystal of tin selenide with a ZT of 3.1. Yet the material was difficult to make and too fragile to work with. “For practical applications, it’s a non-starter,” Kanatzidis says.

So, his team decided to make its thermoelectrics from readily available tin and selenium powders, an approach that, once processed, makes grains of polycrystalline tin selenide instead of the single crystals. The polycrystalline grains are cheap and can be heated and compressed into ingots that are 3 to 5 centimeters long, which can be made into devices. The polycrystalline ingots are also more robust, and Kanatzidis expected the boundaries between the individual grains to slow the passage of heat. But when his team tested the polycrystalline materials, the thermal conductivity shot up, dropping their ZT scores as low as 1.2.

In 2016, the Northwestern team discovered the source of the problem: an ultrathin skin of tin oxide was forming around individual grains of polycrystalline tin selenide before they were pressed into ingots. And that skin acted as an express lane for the heat to travel from grain to grain through the material. So, in their current study, Kanatzidis and his colleagues came up with a way to use heat to drive any oxygen away from the powdery precursors, leaving pristine polycrystalline tin selenide, whereas other devices can generate electricity from thin air using ambient moisture.

The result, which they report today in Nature Materials, was not only a thermal conductivity below that of single-crystal tin selenide but also a ZT of 3.1, a development that echoes nighttime renewable devices showing electricity from cold conditions. “This opens the door for new devices to be built from polycrystalline tin selenide pellets and their applications to be explored,” Kanatzidis says.

Getting through that door will still take some time. The polycrystalline tin selenide the team makes is spiked with sodium atoms, creating what is known as a “p-type” material that conducts positive charges. To make working devices, researchers also need an “n-type” version to conduct negative charges.

Zhao’s team recently reported making an n-type single-crystal tin selenide by spiking it with bromine atoms. And Kanatzidis says his team is now working on making an n-type polycrystalline version. Once n-type and p-type tin selenide devices are paired, researchers should have a clear path to making a new generation of ultra-efficient thermoelectric generators. Those could be installed everywhere from automobile exhaust pipes to water heaters and industrial furnaces to scavenge energy from some of the 65% of fossil fuel energy that winds up as waste heat.

$550 Million in Clean Energy Funding to Benefit More than 250 Million Americans

EECBG Program Funding empowers states, Tribes, and local governments with DOE grants to deploy clean energy, energy efficiency, EV infrastructure, and community solar, cutting emissions, lowering utility bills, and advancing net-zero decarbonization.

 

Key Points

EECBG Program Funding is a $550M DOE grant for states, Tribes, and governments to deploy clean energy and efficiency.

✅ Supports EV infrastructure and community solar deployment

✅ Cuts emissions and lowers utility costs via efficiency

✅ Prioritizes Justice40 benefits for underserved communities

 

The Biden-Harris Administration, through the U.S. Department of Energy (DOE), today released a Notice of Intent announcing $550 million to support community-based clean energy in state, Tribal, and local governments — serving more than 250 million Americans. This investment in American communities, through the Energy Efficiency and Conservation Block Grant (EECBG) Program, will support communities across the country to develop local programming and deploy clean energy technologies to cut emissions, advance a 90% carbon-free electricity goal nationwide, and reduce consumers’ energy costs, and help meet President Biden’s goal of a net-zero economy by 2050. 

“This funding is a streamlined and flexible tool for local governments to build their electricity future with clean energy,” said U.S. Secretary of Energy Jennifer M. Granholm. “State, local, and Tribal communities nationwide will be able to leverage this funding to drive greater energy efficiency and conservation practices to lower utility bills and create healthier environments for American families.”   

The EECBG Program will fund 50 states, five U.S. territories, the District of Columbia, 774 Tribes, and 1,878 local governments in a variety of capacity-building, planning, and infrastructure efforts to reduce carbon emissions and energy use and improve energy efficiency in the transportation, building, and other related sectors. For example, communities with this funding can build out electric vehicle infrastructure and deploy community solar to serve areas that otherwise do not have access to electric vehicles or clean energy, particularly through a rural energy security program where appropriate.  

The $550 million made available through the Bipartisan Infrastructure Law (BIL) represents the second time that the EECBG Program has been funded, the first of which was through the American Recovery and Reinvestment Act of 2009. With this most recent funding, communities can build on prior investments and leverage additional clean energy funding from DOE, other federal agencies, and the private sector to achieve sustained impacts, supported by a Clean Electricity Standard where applicable, that can put their communities on a pathway to decarbonization. 

Through the EECBG Program and the Office of State and Community Energy Programs (SCEP), DOE will support the many diverse state, local, and tribal communities across the U.S., including efforts to revitalize coal communities through clean energy, as they implement this funding and other clean energy projects. To ensure no communities are left behind, the program aligns with President’s Justice40 initiative and efforts toward equity in electricity regulation to help ensure that 40% of the overall benefits of clean energy investments go to underserved and overburdened communities.
