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.

Seven small UK energy suppliers must pay renewables fees or risk losing licence

Ofgem Renewables Obligations drive supplier payments for renewables fees, feed-in tariffs, and renewable generation, with non-payment risking supply licences amid the price cap and volatile wholesale prices across the UK energy market.

 

Key Points

Mandatory payments by suppliers funding renewables via feed-in tariffs; non-payment can trigger supply licence revoking.

✅ Covers Renewables Obligation and Feed-in Tariff scheme compliance.

✅ Non-payment can lead to Ofgem action and licence loss.

✅ Affected by price cap and wholesale price volatility.

 

Seven small British energy suppliers owe a total of 34 million pounds ($43.74 million) in renewables fees, amid a renewables backlog that has stalled projects, and could face losing their supply licences if they cannot pay, energy regulator Ofgem reports.

Under Britain’s energy market rules, suppliers of energy must meet so-called renewables obligations and feed-in tariffs, including households' ability to sell solar power back to energy firms, which are imposed on them by the government to help fund renewable power generation.

Several small energy companies have gone bust over the past two years, a trend echoed by findings from a global utility study on renewable priorities, as they struggled to pay the renewables fees and as their profits were affected by a price cap on the most commonly used tariffs and fluctuating wholesale prices, even as a 10 GW contract brings new renewable capacity onto the UK grid.

Ofgem has called on the companies to make necessary payments by Oct. 31, as moves to offer community-generated power to all UK customers progress.

“If they do not pay Ofgem could start the process of revoking their licences to supply energy,” it said in a statement, as offshore wind power continues to scale nationwide.

The seven suppliers are, amid debates over clean energy impacts, Co-Operative Energy Limited; Flow Energy Limited; MA Energy Limited; Nabuh Energy Limited; Robin Hood Energy Limited; Symbio Energy Limited and Tonik Energy Limited. ($1 = 0.7773 pounds)

Ontario Energy minister downplays dispute between auditor, electricity regulator

Ontario IESO Accounting Dispute highlights tensions over public sector accounting standards, auditor general oversight, electricity market transparency, KPMG advice, rate-regulated accounting, and an alleged $1.3B deficit understatement affecting Hydro bills and provincial finances.

 

Key Points

A PSAS clash between Ontario's auditor general and the IESO, alleging a $1.3B deficit impact and transparency failures.

✅ Auditor alleges deficit understated by $1.3B

✅ Dispute over PSAS vs US-style accounting

✅ KPMG support, transparency and co-operation questioned

 

The bad blood between the Ontario government and auditor general bubbled to the surface once again Monday, with the Liberal energy minister downplaying a dispute between the auditor and the Crown corporation that manages the province's electricity market, even as the government pursued legislation to lower electricity rates in the province.

Glenn Thibeault said concerns raised by auditor general Bonnie Lysyk during testimony before a legislative committee last week aren't new and the practices being used by the Independent Electricity System Operator are commonly endorsed by major auditing firms.

"(Lysyk) doesn't like the rate-regulated accounting. We've always said we've relied on the other experts within the field as well, plus the provincial controller," Thibeault said.

#google#

"We believe that we are following public sector accounting standards."

Thibeault said that Ontario Power Generation, Hydro One and many other provinces and U.S. states use the same accounting practices.

"We go with what we're being told by those who are in the field, like KPMG, like E&Y," he said.

But a statement from Lysyk's office Monday disputed Thibeault's assessment.

"The minister said the practices being used by the IESO are common in other jurisdictions," the statement said.

"In fact, the situation with the IESO is different because none of the six other jurisdictions with entities similar to the IESOuse Canadian Public Sector Accounting Standards. Five of them are in the United States and use U.S. accounting standards."

Lysyk said last week that the IESO is using "bogus" accounting practices and her office launched a special audit of the agency late last year after the agency changed their accounting to be more in line with U.S. accounting, following reports of a phantom demand problem that cost customers millions.

Lysyk said the accounting changes made by the IESO impact the province's deficit, understating it by $1.3 billion as of the end of 2017, adding that IESO "stalled" her office when it asked for information and was not co-operative during the audit.

Lysyk's full audit of the IESO is expected to be released in the coming weeks and is among several accounting disputes her office has been engaged in with the Liberal government over the past few years.

Last fall, she accused the government of purposely obscuring the true financial impact of its 25% hydro rate cut by keeping billions in debt used to finance that plan off the province's books. Lysyk had said she would audit the IESO because of its role in the hydro plan's complex accounting scheme.

"Management of the IESO and the board would not co-operate with us, in the sense that they continually say they're co-operating, but they stalled on giving us information," she said last week.

Terry Young, a vice-president with the IESO, said the agency has fully co-operated with the auditor general. The IESO opened up its office to seven staff members from the auditor's office while they did their work.

"We recognize the work that she's doing and to that end we've tried to fully co-operate," he said. "We've given her all of the information that we can."

Young said the change in accounting standards is about ensuring greater transparency in transactions in the energy marketplace.

"It's consistent with many other independent electricity system operators are doing," he said.

Lysyk also criticized IESO's accounting firm, KPMG, for agreeing with the IESO on the accounting standards. She was critical of the firm billing taxpayers for nearly $600,000 work with the IESO in 2017, compared to their normal yearly audit fee of $86,500.

KPMG spokeswoman Lisa Papas said the accounting issues that IESO addressed during 2017 were complex, contributing to the higher fees.

The accounting practices the auditor is questioning are a "difference of professional judgement," she said.

"The standards for public sector organizations such as IESO are principles-based standards and, accordingly, require the exercise of considerable professional judgement," she said in a statement.

"In many cases, there is more than one acceptable approach that is compliant with the applicable standards."

Progressive Conservative energy critic Todd Smith said the government isn't being transparent with the auditor general or taxpayers, aligning with calls for cleaning up Ontario's hydro mess in the sector.

"Obviously, they have some kind of dispute but the auditor's office is saying that the numbers that the government is putting out there are bogus.

Those are her words," he said. "We've always said that we believe the auditor general's are the true numbers for the
province of Ontario."

NDP energy critic Peter Tabuns said the Liberal government has decided to "play with accounting rules" to make its books look better ahead of the spring election, despite warnings that electricity prices could soar if costs are pushed into the future.

Trump's Canada Tariff May Spike NY Energy Prices

25% Tariff on Canadian Imports threatens New York energy markets, disrupting hydroelectric power and natural gas supply chains, raising electricity prices, increasing gas costs, and intensifying trade tensions, policy uncertainty, and cross-border logistics risks.

 

Key Points

A U.S. policy imposing 25% duties on Canadian goods, risking higher New York electricity and natural gas costs.

✅ Hydroelectric and gas imports face costlier cross-border flows

✅ Higher utility bills for NY households and businesses

✅ Supply chain volatility and policy uncertainty increase

 

President Donald Trump announced the imposition of a 25% tariff on all imports from Canada, citing concerns over drug trafficking and illegal immigration. This decision has raised significant concerns among experts and residents in New York, who warn that the tariff could lead to increased electricity and gas prices in the state.

Impact on New York's Energy Sector

New York relies heavily on energy imports from Canada, particularly electricity and natural gas. Canada is a major supplier of hydroelectric power to the northeastern United States, including New York, with its electricity exports at risk amid trade tensions. The imposition of a 25% tariff on Canadian goods could disrupt this supply chain, leading to higher energy costs for consumers and businesses in New York. Justin Wilcox, an energy analyst, stated, "If the tariff is implemented, it could lead to increased costs for electricity and gas, affecting both consumers and businesses."

Potential Economic Consequences

The increased energy costs could have broader economic implications for New York, and some experts advise against cutting Quebec's exports to avoid exacerbating market volatility. Higher electricity and gas prices may lead to increased operational costs for businesses, potentially resulting in higher prices for goods and services, while tariff threats have boosted support for Canadian energy projects that could reshape regional supply. This could exacerbate the cost-of-living challenges faced by residents and strain the state's economy.

Political and Diplomatic Reactions

The tariff has also sparked political and diplomatic reactions, including threats to cut U.S. electricity exports from Ontario that raised tensions. New York Governor Kathy Hochul expressed concern over the potential economic impact, stating, "We are closely monitoring the situation and are prepared to take necessary actions to protect New York's economy." Additionally, Canadian officials have expressed their disapproval of the tariff, and Ontario Premier Doug Ford's Washington meeting underscored ongoing discussions, emphasizing the importance of the trade relationship between the two countries.

Historical Context

This development is part of a broader pattern of trade tensions between the United States and its neighbors. In 2018, the U.S. imposed tariffs on Canadian steel and aluminum, leading to retaliatory measures from Canada. The current situation underscores the ongoing challenges in international trade relations, where a recent tariff threat delayed Quebec's green energy bill and highlighted the potential domestic impacts of such policies.

The imposition of a 25% tariff on Canadian imports by President Trump has raised significant concerns in New York regarding potential increases in electricity and gas prices. Experts warn that this could lead to higher costs for consumers and businesses, with broader economic implications for the state. As the situation develops, it will be crucial to monitor the responses from both state and federal officials, as well as how Canadians support tariffs on energy and minerals may influence policy, and the potential for diplomatic negotiations to address these trade tensions.

Salmon and electricity at center of Columbia River treaty negotiations

Columbia River Treaty Negotiations involve Canada-U.S. talks on B.C. dams, flood control, hydropower sharing, and downstream benefits, prioritizing ecosystem health, First Nations rights, and salmon restoration while balancing affordable electricity for northwest consumers.

 

Key Points

Talks to update flood control, hydropower, and ecosystem terms for fair benefits to B.C. and U.S. communities.

✅ Public consultations across B.C.'s Columbia Basin

✅ First Nations priorities include salmon restoration

✅ U.S. seeks cheaper power; B.C. defends downstream benefits

 

With talks underway between Canada and the U.S. on the future of the Columbia River Treaty, the B.C. New Democrats have launched public consultations in the region most affected by the high-stakes negotiation.

“We want to ensure Columbia basin communities are consulted, kept informed and have their voices heard,” said provincial cabinet minister Katrine Conroy via a press release announcing meetings this month in Castlegar, Golden, Revelstoke, Nakusp, Nelson and other communities.

As well as having cabinet responsibility for the talks, Conroy’s Kootenay West riding includes several places that were inundated under the terms of the 1964 flood control and power generation treaty.

“We will continue to work closely with First Nations affected by the treaty, to ensure Indigenous interests are reflected in the negotiations,” she added by way of consolation to Indigenous people who’ve been excluded from the negotiating teams on both sides of the border.

#google#

The stakes are also significant for the province as a whole. The basics of the treaty saw B.C. build dams to store water on this side of the border, easing the flood risk in the U.S. and allowing the flow to be evened out through the year. In exchange, B.C. was entitled to a share of the additional hydro power that could be generated in dams on the U.S. side.

B.C.’s sale of those downstream benefits to the U.S has poured almost $1.4 billion into provincial coffers over the past 10 years, albeit at a declining rate these days amid scrutiny from a regulator report on BC Hydro that raised concerns, because of depressed prices for cross-border electricity sales.

Politicians on the U.S. side have long sought to reopen the treaty, believing there was now a case for reducing B.C.’s entitlement.

They did not get across the threshold under President Barack Obama.

Then, last fall his successor Donald Trump served notice of intent, initiating the formal negotiations that commenced with a two day session last week in Washington, D.C. The next round is set for mid-August in B.C.

American objectives in the talks include “continued, careful management of flood risk; ensuring a reliable and economical power supply; and better addressing ecosystem concerns,” with recognition of recent BC Hydro demand declines during the pandemic.

“Economical power supply,” being a diplomatic euphemism for “cheaper electricity for consumers in the northwest states,” achievable by clawing back most of B.C.’s treaty entitlement.

On taking office last summer, the NDP inherited a 14-point statement of principles setting out B.C. hopes for negotiations to “continue the treaty” while “seeking improvements within the existing framework” of the 54-year-old agreement.

The New Democrats have endorsed those principles in a spirit of bipartisanship, even as Manitoba Hydro governance disputes play out elsewhere in Canada.

“Those principles were developed with consultation from throughout the region,” as Conroy advised the legislature this spring. “So I was involved, as well, in the process and knew what the issues were, right as they would come up.”

The New Democrats did chose to put additional emphasis on some concerns.

“There is an increase in discussion with Canada and First Nations on the return of salmon to the river,” she advised the house, recalling how construction of the enormous Grand Coulee Dam on the U.S. side in the 1930s wiped out salmon runs on the upper Columbia River.

“There was no consideration then for how incredibly important salmon was, especially to the First Nations people in our region. We have an advisory table that is made up of Indigenous representation from our region, and also we are discussing with Canada that we need to see if there’s feasibility here.”

As to feasibility, the obstacles to salmon migration in the upper reaches of the Columbia include the 168-metre high Grand Coulee and the 72-metre Chief Joseph dams on the U.S. side, plus the Keenleyside (52 metres), Revelstoke (175 metres) and Mica (240 metres) dams on the Canadian side.

Still, says Conroy “the First Nations from Canada and the tribes from the United States, have been working on scientific and technical documents and research to see if, first of all, the salmon can come up, how they can come up, and what the things are that have to be done to ensure that happens.”

The New Democrats also put more emphasis on preserving the ecosystem, aligning with clean-energy efforts with First Nations that support regional sustainability.

“I know that certainly didn’t happen in 1964, but that is something that’s very much on the minds of people in the Columbia basin,” said Conroy. “If we are going to tweak the treaty, what can we do to make sure the voices of the basin are heard and that things that were under no consideration in the ’60s are now a topic for consideration?”

With those new considerations, there’s still the status quo concern of preserving the downstream benefits as a trade off for the flooding and other impacts on this side of the border.

The B.C. position on that score is the same under the New Democrats as it was under the Liberals, despite a B.C. auditor general report on deferred BC Hydro costs.

“The level of benefits to B.C., which is currently solely in the form of the (electricity) entitlement, does not account for the full range of benefits in the U.S. or the impacts in B.C.,” says the statement of principle.

“All downstream U.S. benefits such as flood risk management, hydropower, ecosystems, water supply (including municipal, industrial and agricultural uses), recreation, navigation and other related benefits should be accounted for and such value created should be shared equitably between the two countries.”

No surprise if the Americans do not see it the same way.  But that is a topic for another day.

Ontario Poised to Miss 2030 Emissions Target

Ontario Poised to Miss 2030 Emissions Target highlights how rising greenhouse gas emissions from electricity generation and natural gas power plants threaten Ontario’s climate goals, environmental sustainability, and clean energy transition efforts amid growing economic and policy challenges.

 

Why is Ontario Poised to Miss 2030 Emissions Target?

Ontario Poised to Miss 2030 Emissions Target examines the province’s setback in meeting climate goals due to higher power-sector emissions and shifting energy policies.

✅ Rising greenhouse gas emissions from gas-fired electricity generation

✅ Climate policy uncertainty and missed environmental targets

✅ Balancing clean energy transition with economic pressures

Ontario’s path toward meeting its 2030 greenhouse gas emissions target has taken a sharp turn for the worse, according to internal government documents obtained by Global News. The province, once on track to surpass its reduction goals, is now projected to miss them—largely due to rising emissions from electricity generation, even as the IEA net-zero electricity report highlights rising demand nationwide.

In October 2024, the Ford government’s internal analysis indicated that Ontario was on track to reduce emissions by 28 percent below 2005 levels by 2030, effectively exceeding its target. But a subsequent update in January 2025 revealed a grim reversal. The new forecast showed an increase of about eight megatonnes (Mt) of emissions compared to the previous model, with most of the rise attributed to the province’s energy policies.

“This forecast is about 8 Mt higher than the October 2024 forecast, mainly due to higher electricity sector emissions that reflect the latest ENERGY/IESO energy planning and assumptions,” the internal document stated.

While the analysis did not specify which policy shifts triggered the change, experts point to Ontario’s growing reliance on natural gas. The use of gas-fired power plants has surged to fill temporary gaps created by nuclear refurbishment projects and other grid constraints, even as renewable energy’s role grows. In fact, natural gas generation in early 2025 reached its highest level since 2012.

The internal report cited “changing electricity generation,” nuclear power refurbishment, and “policy uncertainty” as major risks to achieving the province’s climate goals. But the situation may be even worse than the government’s updated forecast suggests.

On Wednesday, Ontario’s auditor general warned that the January projections were overly optimistic. The watchdog’s new report concluded the province could fall even further behind its 2030 emissions target, noting that reductions had likely been overestimated in several sectors, including transportation—such as electric vehicle sales—and waste management. “An even wider margin” of missed goals was now expected, the auditor said.

Environment Minister Todd McCarthy defended the government’s position, arguing that climate goals must be balanced against economic realities. “We cannot put families’ financial, household budgets at risk by going off in a direction that’s not achievable,” McCarthy said.

The minister declined to commit to new emissions targets beyond 2030—or even to confirm that the existing goals would be met—but insisted efforts were ongoing. “We are continuing to meet our commitment to at least try to meet our commitment for the 2030 target,” he told reporters. “But targets are not outcomes. We believe in achievable outcomes, not unrealistic objectives.”

Environmental advocates warn that Ontario’s reliance on fossil-fuel generation could lock the province into higher emissions for years, undermining national efforts to decarbonize Canada’s electricity grid. With cleaning up Canada’s electricity expected to play a central role in both industrial growth and climate action, the province’s backslide represents a significant setback for Canada’s overall emissions strategy.

Other provinces face similar challenges; for example, B.C. is projected to miss its 2050 targets by a wide margin.

As Ontario weighs its next steps, the tension between energy security, affordability, and environmental responsibility continues to define the province’s path toward a lower-carbon future and Canada’s 2050 net-zero target over the long term.

APS asks customers to conserve energy after recent blackouts in California

Arizona Energy Conservation Alert urges APS and TEP customers to curb usage during a heatwave, preventing rolling blackouts, easing peak demand, and supporting grid reliability by raising thermostats, delaying appliances, and pausing pool pumps.

 

Key Points

A utility request during extreme heat to cut demand and protect grid reliability, helping prevent outages.

✅ Raise thermostats to 80 F or higher during peak hours

✅ Delay washers, dryers, dishwashers until after 8 p.m.

✅ Pause pool pumps; switch off nonessential lights and devices

 

After excessive heat forced rolling blackouts for thousands of people across California Friday and Saturday, Arizona Public Service Electric is asking customers to conserve energy this afternoon and evening.

“Given the extended heat wave in the western United States and climate-related grid risks that utilities are monitoring, APS is asking customers to conserve energy due to extreme energy demand that is driving usage higher throughout the region with today’s high temperatures,” APS said in a statement.

Tucson Electric Power has made a similar request of customers in its coverage area.


APS is asking customers to conserve energy in the following ways Tuesday until 8 p.m.:

  • Raise thermostat settings to no lower than 80 degrees.
  • Turn off extra lights and avoid use of discretionary major appliances such as clothes washers, dryers and dishwashers.
  • Avoid operation of pool pumps.

The request from APS also came just hours after Arizona Corporation Commission Chairman Bob Burns sent a letter to electric utilities under the commission's umbrella, like APS, to see if they are in good shape or anticipate any problems given looming shortages in California. He requested the companies respond by noon Friday.


"The whole plan is to take a look at the system early in the Summer," Burns said. "Early May we look at the system, make sure we're ready and able to serve the public throughout the entire heat cycle."

Burns told ABC15 the Summer Preparedness workshop with utilities took place in May and the regulated utilities reported they were well equipped to meet the anticipated peaks of the Summer, even as supply-chain pressures mount across the industry. Tuesday's letter to the electric companies seeks to see if they are still able to "adequately, safely and reliably" serve customers through the heatwave, or if what happened in California could take place here.

"With the activities that are occurring over in California, including tight grid conditions that have repeatedly tested operators, we just want to double check," Burns said.

An APS representative told ABC15 they have adequate supply and reserve and don't anticipate any problems.

However, the rolling blackouts in California also caught the attention of Commissioner Lea Marquez Peterson. She is calling on the chairman to hold an emergency meeting amid wildfire concerns across California and the region.

"The risk to Arizonans and the fact that energy could be interrupted, that we had some kind of rolling blackout like California would have, would be really a public health issue," Peterson said. "It could be life and death in some cases for vulnerable populations."
