Dr. Mark Hall will be getting an electric bill a few days before Christmas, and he believes it will bring joy to his world.

That is when he will get a bill that reflects the first full month's usage of the solar energy system that covers almost all the roof of his Blount Veterinary Clinic in Maryville.

Because sunshine is free, "It will probably pay the whole electric bill," Hall said.

Alternate Energy Group of Knoxville installed the 33 solar panels on the clinic's roof, going online October 22 with a system that the veterinarian expects to take a substantial bite out of his power costs.

"I am satisfied with the immediate benefits I see on paper," Hall said, noting that it could be 7 1/2 years before the system pays for itself. "You have to take the long view and look at the return on investment."

Dwayne Cutshall, one of three partners in Alternate Energy Group, said Hall currently pays 11 cents per kilowatt hour to city of Maryville utilities, but he gets a credit of more than twice that - 23 cents per kilowatt hour - for the solar energy generated on his roof.

The potential savings is readily apparent.

If Hall can generate half his power, Cutshall said, all his power costs are covered.

The 33-panel system is as much as the roof of Hall's clinic will hold, Cutshall said.

Hall's last utility bill showed he generated 527 kilowatt hours of electricity from the online date through November 12, giving him a $113.83 credit against his bill. And that encompasses days of increasingly less sunlight and more cloud cover.

Hall said that the reason the utilities - TVA and the city of Maryville - can pay him twice as much for the power he generates than for the power they provide is that the transmission cost of his solar power is far below that of TVA's.

Whereas the TVA power may be transmitted from hundreds of miles away - with much being lost in transit - Hall's excess solar power may travel only to surrounding businesses and homes.

Hall's system is capable of generating 230 watts of DC power per solar panel, totaling 7.59 kilowatts an hour. That power is converted to AC power by a device on the side of Hall's building that works at more than 95 percent efficiency, Cutshall said.

The system cost Hall $53,750, but that was offset by a $1,000 green power award when the system went operational. Plus, Hall gets $15,000 in a federal stimulus money grant administered by the Tennessee Solar Institute at the University of Tennessee and a federal tax credit of more than $16,000 on his 2010 tax return.

Thus, almost half the cost of the solar system is paid for with government money, and that does not include deductions for depreciation, if Hall chooses to claim them.

Hall's array faces a few degrees off due south, and Cutshall said it weighs about 4-5 pounds per square foot. It is designed to stay put in a 155-mph wind and withstand half-inch hail.

It is warranted to still be producing 80 percent of its present capacity in 25 years, Cutshall said.

Cutshall's partners in Alternate Energy Group are the father-son team of Phil R. Hicks Jr. and his son Phil Hicks.

Planning for Toronto?s Growing Electricity Needs

Toronto Grid Upgrade expands electricity capacity and reliability with new substations, upgraded transmission lines, and integrated renewable energy, supporting EV growth, sustainability goals, and resilient power for Toronto's growing residential and commercial sectors.

 

Key Points

A joint plan to boost grid capacity, add renewables, and improve reliability for Toronto's rising power demand.

✅ New substations and upgraded transmission lines increase capacity

✅ Integrates solar, wind, and storage for cleaner, reliable power

✅ Supports EV adoption, reduces outages, and future-proofs the grid

 

As Toronto's population and economy continue to expand, the surge in electricity demand in the city is also increasing rapidly. In response, the Ontario government, in partnership with the City of Toronto and various stakeholders, has launched an initiative to enhance the electricity infrastructure to meet future needs.

The Ontario Ministry of Energy and the City of Toronto are focusing on a multi-faceted approach that includes upgrades to existing power systems and the integration of renewable energy sources, as well as updated IoT cybersecurity standards for sector devices. This initiative is critical as Toronto looks towards a sustainable future, with projections indicating significant growth in both residential and commercial sectors.

Energy Minister Todd Smith highlighted the urgency of this project, stating, “With Toronto's growing population and dynamic economy, the need for reliable electricity cannot be overstated. We are committed to ensuring that our power systems are not only capable of meeting today's demands but are also future-proofed against the needs of tomorrow.”

The plan involves substantial investments in grid infrastructure to increase capacity and improve reliability. This includes the construction of new substations and the enhancement of old ones, along with the upgrading of transmission lines and exploration of macrogrids to strengthen reliability. These improvements are designed to reduce the frequency and severity of power outages while accommodating new developments and technologies such as electric vehicles, which are expected to place additional demands on the system.

Additionally, the Ontario government is exploring the potential for renewable energy sources, such as rooftop solar grids and wind, to be integrated into the city’s power grid. This shift towards green energy is part of a broader effort to reduce carbon emissions and promote environmental sustainability.

Toronto Mayor John Tory emphasized the collaborative nature of this initiative, stating, “This is a prime example of how collaboration between different levels of government and the private sector can lead to innovative solutions that benefit everyone. By enhancing our electricity infrastructure, we are not only improving the quality of life for our residents but also supporting Toronto's competitive edge as a global city.”

The project also includes a public engagement component, where citizens are encouraged to provide input on the planning and implementation phases. This participatory approach ensures that the solutions developed are in alignment with the needs and expectations of Toronto's diverse communities.

Experts agree that the timing of these upgrades is critical. As urban populations grow, the strain on infrastructure, especially in a powerhouse like Toronto, can lead to significant challenges. Proactive measures, such as those being implemented by Ontario and Toronto, and mirrored by British Columbia's clean energy shift underway on the west coast, are essential in avoiding potential crises and ensuring economic stability.

The success of this initiative could serve as a model for other cities facing similar challenges, highlighting the importance of forward-thinking and cooperation in urban planning and energy management. As Toronto moves forward with these ambitious plans, the eyes of the world, particularly other urban centers, will be watching and learning how to similarly tackle the dual challenges of growth and sustainability, with recent examples like London's newest electricity tunnel demonstrating large-scale grid upgrades.

This strategic approach to managing Toronto's electricity needs reflects a comprehensive understanding of the complexities involved in urban energy systems and a commitment to ensuring a resilient and sustainable future that aligns with Canada's net-zero grid by 2050 goals at the national level for all residents.

Abu Dhabi seeks investors to build hydrogen-export facilities

ADNOC Hydrogen Export Projects target global energy transition, courting investors and equity stakes for blue and green hydrogen, ammonia shipping, CCS at Ruwais, and long-term supply contracts across power, transport, and industrial sectors.

 

Key Points

ADNOC plans blue and green hydrogen exports, leveraging Ruwais, CCS, and ammonia to secure long-term supply.

✅ Blue hydrogen via gas reforming with CCS; ammonia for shipping.

✅ Green hydrogen from solar-powered electrolysis under development.

✅ Ruwais expansions and Fertiglobe ammonia tie-up target long-term supply.

 

Abu Dhabi is seeking investors to help build hydrogen-export facilities, as Middle Eastern oil producers plan to adopt cleaner energy solutions, sources told Bloomberg.

Abu Dhabi National Oil Company (ADNOC) is holding talks with energy companies for them to purchase equity stakes in the hydrogen projects, the sources referred, as Germany's hydrogen strategy signals rising import demand.

ADNOC, which already produces hydrogen for its refineries, also aims to enter into long-term supply contracts, as Canada-Germany clean energy cooperation illustrates growing cross-border demand, before making any progress with these investments.

Amid a global push to reduce greenhouse-gas emissions, the state-owned oil companies in the Gulf region seek to turn their expertise in exporting liquid fuel into shipping hydrogen or ammonia across the world for clean and universal electricity needs, transport, and industrial use.

Most of the ADNOC exports are expected to be blue hydrogen, created by converting natural gas and capturing the carbon dioxide by-product that can enable using CO2 to generate electricity approaches, according to Bloomberg.

The sources said that the Abu Dhabi-based company will raise its production of hydrogen by expanding an oil-processing plant and the Borouge petrochemical facility at the Ruwais industrial hub, supporting a sustainable electric planet vision, as the extra hydrogen will be used for an ammonia facility planned with Fertiglobe.

Abu Dhabi also plans to develop green hydrogen, similar to clean hydrogen in Canada initiatives, which is generated from renewable energy such as solar power.

Noteworthy to mention, in May 2021, ADNOC announced that it will construct a world-scale blue ammonia production facility in Ruwais in Abu Dhabi to contribute to the UAE's efforts to create local and international hydrogen value chains.

Hydro-Quebec adopts a corporate structure designed to optimize the energy transition

Hydro-Québec Unified Corporate Structure advances the energy transition through integrated planning, strategy, infrastructure delivery, and customer operations, aligning generation, transmission, and distribution while ensuring non-discriminatory grid access and agile governance across assets and behind-the-meter technologies.

 

Key Points

A cross-functional model aligning strategy, planning, and operations to accelerate Quebec's low-carbon transition.

✅ Four groups: strategy, planning, infrastructure, operations.

✅ Ensures non-discriminatory transmission access compliance.

✅ No staff reductions; staged implementation from Feb 28.

 

As Hydro-Que9bec prepares to play a key role in the transition to a low-carbon economy, the complexity of the work to be done in the coming decade requires that it develop a global vision of its operations and assets, from the drop of water entering its turbines to the behind-the-meter technologies marketed by its subsidiary Hilo. This has prompted the company to implement a new corporate structure that will maximize cooperation and agility, including employee-led pandemic support that builds community trust, making it possible to bring about the energy transition efficiently with a view to supporting the realization of Quebecers’ collective aspirations.

Toward a single, unified Hydro

Hydro-Québec’s core mission revolves around four major functions that make up the company’s value chain, alongside policy choices like peak-rate relief during emergencies. These functions consist of:

  1. Developing corporate strategies based on current and future challenges and business opportunities
  2. Planning energy needs and effectively allocating financial capital, factoring in pandemic-related revenue impacts on demand and investment timing
  3. Designing and building the energy system’s multiple components
  4. Operating assets in an integrated fashion and providing the best customer experience by addressing customer choice and flexibility expectations across segments.

Accordingly, Hydro-Québec will henceforth comprise four groups respectively in charge of strategy and development; integrated energy needs planning; infrastructure and the energy system; and operations and customer experience, including billing accuracy concerns that can influence satisfaction. To enable the company to carry out its mission, these groups will be able to count on the support of other groups responsible for corporate functions.

Across Canada, leadership changes at other utilities highlight the need to rebuild ties with governments and investors, as seen with Hydro One's new CEO in Ontario.

“For over 20 years, Hydro-Québec has been operating in a vertical structure based on its main activities, namely power generation, transmission and distribution. This approach must now give way to one that provides a cross-functional perspective allowing us to take informed decisions in light of all our needs, as well as those of our customers and the society we have the privilege to serve,” explained Hydro-Québec’s President and Chief Executive Officer, Sophie Brochu.

In terms of gender parity, the management team continues to include several men and women, thus ensuring a diversity of viewpoints.

Hydro-Québec’s new structure complies with the regulatory requirements of the North American power markets, in particular with regard to the need to provide third parties with non-discriminatory access to the company’s transmission system. The frameworks in place ensure that certain functions remain separate and help coordinate responses to operational events such as urban distribution outages that challenge continuity of service.

These changes, which will be implemented gradually as of Monday, February 28, do not aim to achieve any staff reductions.

Clean, affordable electricity should be an issue in the Ontario election

Ontario Electricity Supply Gap threatens growth as demand from EVs, heat pumps, industry, and greenhouses surges, pressuring the grid and IESO to add nuclear, renewables, storage, transmission, and imports while meeting net-zero goals.

 

Key Points

The mismatch as Ontario's electricity demand outpaces supply, driven by electrification, EVs, and industrial growth.

✅ Demand growth from EVs, heat pumps, and electrified industry

✅ Capacity loss from Pickering retirement and Darlington refurb

✅ Options: SMRs, renewables, storage, conservation, imports

 

Ontario electricity demand is forecast to soon outstrip supply as it confronts a shortage in the coming years, a problem that needs attention in the upcoming provincial election.

Forecasters say Ontario will need to double its power supply by 2050 as industries ramp up demand for low-emission clean power options and consumers switch to electric vehicles and space heating. But while the Ford government has made a flurry of recent energy announcements, including a hydrogen project at Niagara Falls and an interprovincial agreement on small nuclear reactors, it has not laid out how it intends to bulk up the province’s power supply.

“Ontario is entering a period of widening electricity shortfalls,” says the Ontario Chamber of Commerce. “Having a plan to address those shortfalls is essential to ensure businesses can continue investing and growing in Ontario with confidence.”

The supply and demand mismatch is coming because of brisk economic growth combined with increasing electrification to balance demand and emissions and meet Canada’s goal to reduce CO2 emissions by 40 per cent by 2030 and to net-zero by 2050.

Hamilton’s ArcelorMittal Dofasco and Algoma Steel in Sault Ste. Marie are leaders on this transformation. They plan to replace their blast furnaces and basic oxygen furnaces later this decade with electric arc furnaces (EAFs), reducing annual CO2 emissions by three million tonnes each.


Dofasco, which operates an EAF that is already the single largest electricity user in Ontario, plans to build a second EAF and a gas-fired ironmaking furnace, which can also be powered with zero-carbon hydrogen produced from electricity, once it becomes available.

Other new projects in the agriculture, mining and manufacturing sectors are also expected to be big power users, including the recently announced $5 billion Stellantis-LG electric vehicle battery plant in Windsor. Five new transmission lines will be built to service the plant and the burgeoning greenhouse industry in southwestern Ontario. The greenhouses alone will require enough additional electricity to power a city the size of Ottawa.

On top of these demands, growing numbers of Ontario drivers are expected to switch to electric vehicles and many homeowners and business owners are expected to convert from gas heating to heat pumps and electric heating.

Ontario is recognized as one of the cleanest electricity systems in the world, with over 90 per cent of its capacity from low-emission nuclear, hydro, wind and other renewable generation. Only nine per cent comes from CO2-emitting gas plants. But that’s about to get dirtier according to analysts.

Annual electricity demand is expected to grow from 140 terawatt hours (a terawatt hour is one trillion watts for one hour) currently to about 200 terawatt hours in 2042, according to the Independent Electricity System Operator, the agency that manages Ontario’s grid.

Demand is expected to outstrip currently contracted supply in 2026, reaching a growing supply gap of about 80 terawatt hours by 2042. A big part of this gap is due to the scheduled retirement of the Pickering nuclear station in 2025 and the current refurbishment of the Darlington nuclear station reactors. While the IESO doesn’t expect blackouts or brownouts, it forecasts the province will need to sharply increase expensive power imports and triple the amount of CO2-polluting gas-fired generation.

Without cleaner, lower-cost alternatives, this will mean “a vastly dirtier and more expensive electricity system,” York University researchers Mark Winfield and Collen Kaiser said in a recent commentary.

The party that wins the provincial election will have to make hard decisions on renewable energy, including new wind and solar projects, energy conservation, battery storage, new hydro plants, small nuclear reactors, gas generation and power imports from the U.S. and Quebec. In addition, the federal government is pressing the provinces to meet a new net-zero clean electricity standard by 2035. These decisions will have huge impact on Ontario’s future, with greening the grid costs highlighted in some reports as potentially very high.

With so much at stake, Ontario’s political parties need to tell voters during the upcoming campaign how they would address these enormous challenges.

Germany's Energy Crisis Deepens as Local Utilities Cry for Help

Germany energy liquidity crisis is straining municipal utilities as gas and power prices surge, margin calls rise, and Russian supply cuts bite, forcing state support, interventions, and emergency financing to stabilize households and businesses.

 

Key Points

A cash squeeze on German municipal utilities as soaring gas and power prices trigger margin calls and funding gaps.

✅ Margin calls and spot-market purchases strain cash flow

✅ State liquidity lines and EU collateral support proposed

✅ Gazprom cuts, Uniper distress heighten default risks

 

Germany’s fears that soaring power prices and gas prices could trigger a deeper crisis is starting to get real. 

Several hundred local utilities are coming under strain and need support, according to the head of Germany’s largest energy lobby group. The companies, generally owned by municipalities, supply households and small businesses directly and are a key part of the country’s power and gas network.

“The next step from the government and federal states must be to secure liquidity for these municipal companies,” Kerstin Andreae, chairwoman of the German Association of Energy and Water Industries, told Bloomberg in Berlin. “Prices are rising, and they have no more money to pay the suppliers. This is a big problem.”

Germany’s energy crunch intensified over the weekend after Russia’s Gazprom PJSC halted its key gas pipeline indefinitely, a stark wake-up call for policymakers to reduce fossil fuel dependence. European energy prices have surged again amid concerns over shortages this winter and fears of a worst-case energy scenario across the bloc. 

Many utilities are running into financial issues as they’re forced to cover missing Russian deliveries with expensive supplies on the spot market. German energy giant Uniper SE, which supplies local utilities, warned it will likely burn through a 7 billion-euro ($7 billion) government safety net and will need more help already this month.

Some German local utilities have already sought help, according to a government official, who asked not to be identified in line with briefing rules.  

With Europe’s largest economy already bracing for recession, Chancellor Olaf Scholz’s administration is battling on several fronts, testing the government’s financial capacity. The ruling coalition agreed Sunday on a relief plan worth about 65 billion euros -- part of an emerging energy shield package to contain the fallout of surging costs for households and businesses. 

Starting in October, local utilities will have to pay a levy for the gas acquired, which will further increase their financial burden, Andreae said.

Margin Calls
European gas prices are more than four times higher than usual for this time of year, underscoring why rolling back electricity prices is tougher than it appears for policymakers, as Russia cuts supplies in retaliation for sanctions related to its invasion of Ukraine. When prices peak, energy companies have to pay margin calls, extra collateral required to back their trades.

The problem has hit local utilities in other countries as well. In Austria, the government approved a 2 billion-euro loan for Vienna’s municipal utility last month. 

The European Union is also planning help, floating gas price cap strategies among other tools. The bloc’s emergency measures will include support for electricity producers struggling to find enough cash to guarantee trades, according to European Commission President Ursula von der Leyen.

The situation has worsened in Germany as some of the country’s big gas importers are reluctant to sell more supplies to some of municipal companies amid fears they could default on payments, Andreae said.

Electricity prices spike in Alberta

Alberta electricity price spike drives 25% CPI surge amid heatwave demand, coal-to-gas conversions, hydro shortfalls, and outages; consumers weigh fixed-rate plans, solar panels, home retrofits, and variable rates to manage bills and grid volatility.

 

Key Points

A recent 25% monthly rise in Alberta power prices driven by heatwave demand, constraints, outages, and fuel shifts.

✅ Heatwave pushed summer peak demand near record

✅ Coal-to-gas conversions and outages tightened supply

✅ Fixed-rate plans, solar, retrofits can reduce bill risk

 

Albertans might notice they are paying more when the next electricity bill comes in as bills on the rise in Calgary alongside provincial trends.

According to the consumer price index, Alberta saw its largest monthly increase since July 2015 as the price of electricity in Alberta rose 25 per cent amid rising electricity prices across the province.

“So I paid negative $70 last month. I actually made money. To supply power to the grid,” said Conrad Nobert, with Climate Action Edmonton.

Norbert is an environmental activist who favours solar power and is warning that prices will continue to go up along with the rising effects from climate change.

“My thoughts are that we can mitigate the price of power going up by taking climate action.”

Alberta experienced one of the hottest summers on record and many people were left scrambling to buy air conditioners.

That demand, along with a number of other factors, drove up prices, prompting some households to lock in rates for protection, says an assistant professor at the University of Calgary who teaches electricity systems.

“At the end of June, during the heatwave, we were a couple megawatts shy of setting an all-time record demand for electricity in the province. That would have been the first time that record for demand in the summer. Traditionally Alberta is a winter peaking province, as shown by an electricity usage record during a deep freeze not long ago,” explained Sara Hastings Simon, an assistant professor at the University of Calgary.

Other reasons for the spike: Alberta’s continuing shift from coal to natural-gas-fired power and changes to electricity production and pricing across the market.

There are a few ways consumers can save money on their power bill; installing solar panels and retrofitting your home to opting for a fixed-rate plan, or considering protections like a consumer price cap where applicable.

“So by default, people are put into a variable rate plan, that changes month to month and that helps to manage prices so you don’t get that big surprise at where prices might be. I think we will get a lot more people looking at that option.”

A statement provided by Dale Nally, Alberta’s Associate Minister of natural gas and electricity, noted recent policy changes including the carbon tax repeal and price cap now in place that affect consumers, says in part:

“This period of high market prices is driven by low supplies of hydro-generated electricity from British Columbia and the pacific northwest, scheduled outages for coal-gas-conversions, unplanned infrastructure outages and unprecedented, and record-breaking high demand due to hot weather. We expect some of the factors that have caused recent increases in prices will be short-term.”
