As many as 21,000 Wisconsin Public Service Corp. customers could receive bills for past natural gas or electrical usage after the utility discovered discrepancies between its meters and the amount of energy recorded on some of its automatic reading devices, a company spokeswoman said.
At fault are 1 percent to 3 percent of the devices that take readings of WPSC's 700,000 meters, said spokeswoman Kelly Zagrzebski. The meters themselves are functioning properly and accurately recording energy use, she said.
The company uses reading devices from a number of vendors, and the problem doesn't appear to be isolated to a particular batch of equipment, Zagrzebski said.
Only those customers who were undercharged or overcharged will be notified, Zagrzebski said. Where a discrepancy is found, WPSC workers will check and test the meter. The company then will mail an additional bill or refund on the account.
"We understand that people are disappointed that they were back-billed, but they need to keep in mind that they used the power in the first place," said Zagrzebski, who stressed the Wisconsin Public Service Commission mandates the utility charge customers the full amount for their use.
Rhody Mallick of Kristin's At Middletown Food & Spirits in Stevens Point received a back-billing from WPSC. He was told from September 2005 to January 2007 he was undercharged about $700. He set up an 18-month payment plan to square the bill.
"I don't understand how they can say I used this much gas. How do they prove that? How do they know?" Mallick asked. "Business is tough enough the way it is, and then you get hit with an extra $700. It takes a bite out of you."
Mallick said he felt he had no choice but to pay the $700.
State Rep. Louis Molepske Jr., D-Stevens Point, said he can understand customers' frustration.
"The Public Service Commission has room to be more customer-friendly," he said. "Most people aren't sure where to turn when they have a problem. They just want to know their rates are fair and justified."
In January, the Public Service Commission approved a 6.6 percent rate increase for electricity and a 3.8 percent increase for gas for WPSC to expire at the end of the year. The Green Bay-based company, which serves northeastern and central Wisconsin and an adjacent portion of Upper Michigan, reported a $129 million profit last year.
Hydro One CEO Mark Poweska aims to rebuild ties with Ontario's provincial government, investors, and communities, stabilize the executive team, boost earnings and dividends, and reset strategy after the scrapped Avista deal and regulatory setbacks.
Key Points
He plans to mend government and investor relations, rebuild the C-suite, and refocus growth after the failed Avista bid.
✅ Rebuild ties with Ontario government and regulators
✅ Stabilize executive team and governance
✅ Refocus growth after Avista deal termination
The incoming chief executive officer of Hydro One Ltd. said Thursday that he aims to rebuild the relationship between the Ontario electrical utility and the provincial government, as seen in COVID-19 support initiatives, as well as ties between the company and its investors.
Mark Poweska, the former executive vice-president of operations at BC Hydro, was announced as Hydro One’s new president and CEO in March. His hiring followed a turbulent period for Toronto-based Hydro One, Ontario’s biggest distributor and transmitter of electricity, with large-scale storm restoration efforts underscoring its role.
Hydro One’s former CEO and board of directors departed last year under pressure from a new Ontario government, the utility’s biggest shareholder. Earlier this year, the company’s plan for a $6.7-billion takeover fell apart over concerns of political interference and the utility clashed with the new provincial government and Progressive Conservative Premier Doug Ford over executive compensation levels, amid rate policy debates such as no peak rate cuts for self-isolating customers.
Hydro One facing $885 million charge as regulator upholds tax decision forcing it to share savings with customers
Shares of Hydro One were up more than eight per cent year-to-date on Wednesday, closing at $21.74. However, the stock price was up only six per cent from Hydro One’s 2015 initial public offering price, something its incoming CEO seems set on changing.
“One of my first priorities will be to solidify the executive team and build relationships with the Government of Ontario, our customers, informed by customer flexibility research, and communities, indigenous leaders, investors, and our partners across the electricity sector,” Poweska said Thursday on a conference call outlining Hydro One’s first-quarter results. “At the same time, I will be working to earn the trust and confidence of the investment community.”
Hydro One reported a profit of $171 million for the three months ended March 31, while peers such as Hydro-Québec reported pandemic-related losses as the sector adapted. Net income for the first quarter was down from $222 million a year earlier, which was due to $140 million in costs related to the scrapping of Hydro One’s proposed acquisition of U.S. energy company Avista Corp.
Hydro One Ltd. appointed Mark Poweska as President and CEO.
In January, Hydro One said the proposed takeover of Spokane, Wash.-headquartered Avista, an approximately $6.7-billion deal announced in July 2017, was being called off. As a result, Hydro One said it would pay Avista a US$103 million break fee.
Revenues net of purchased power for the first quarter rose to $952 million, up by 15.4 per cent compared to last year, Hydro One said, helped by higher distribution revenues. Adjusted profit for the quarter, which removes the Avista-related costs, was $311 million, up from $210 million a year ago.
The company is hiking its quarterly dividend to 24.15 cents per share, up five per cent from the last increase in May 2018, while also launching a pandemic relief fund for customers.
Poweska is taking over for acting president and CEO Paul Dobson this month, and the new executive will be charged with revamping Hydro One’s C-suite.
The company’s chief operating officer, chief legal officer, and chief corporate development officer have all departed this year. The company’s chief human resource officer has retired as well, although Poweska did announce Thursday that he had appointed acting chief financial officer Chris Lopez as CFO.
“Hydro One’s significant bench strength and management depth will ensure stability and continuity during this period of transition, as the sector pursues Hydro-Québec energy transition as well,” the company said in its first-quarter earnings press release.
Ontario remains Hydro One’s biggest shareholder, owning approximately 47 per cent of the company.
France Electricity Crisis drives record power prices as nuclear outages squeeze supply, forcing energy imports, fuel oil and coal generation, amid gas market shocks, weak wind output, and freezing weather straining the grid.
Key Points
A French power shortfall from nuclear outages, record prices, heavy imports, and oil-fired backup amid cold weather.
✅ EDF halted reactors; 10% capacity offline, 30% by January
✅ Imports surge; fuel oil and coal units dispatched
✅ Prices spike as gas reverses flow and wind output drops
Electricity prices surged to a fresh record as France scrambled to keep its lights on, sucking up supplies from the rest of Europe.
France, usually an exporter of power, is boosting electricity imports and even burning fuel oil, and has at times limited nuclear output due to high river temperatures during heatwaves. The crunch comes after Electricite de France SA said it would halt four reactors accounting for 10% of the nation’s nuclear capacity, straining power grids already facing cold weather. Six oil-fired units were turned on in France on Tuesday morning, according to a filing with Entsoe.
“It’s illustrating how severe it is when they’re actually starting to burn fuel oil and importing from all these countries,” said Fabian Ronningen, an analyst at Rystad Energy. The unexpected plant maintenance “is reflected in the market prices,” he said
Europe is facing an energy crisis, with utilities relying on coal and oil. Almost 30% of France’s nuclear capacity will be offline at the beginning of January, leaving the energy market at the mercy of the weather. To make matters worse, Germany is closing almost half of its nuclear capacity before the end of the year, as Europe loses nuclear power just when it really needs energy.
German power for delivery next year surged 10% to 278.50 euros a megawatt-hour, while the French contract for January added 9.5% to a record 700.60 euros. Prices also gained, under Europe’s marginal pricing system, as gas jumped after shipments from Russia via a key pipeline reversed direction, flowing eastward toward Poland instead.
Neighboring countries are boosting their exports to France this week to cover for lost nuclear output, with imports from Germany rising to highest level in at least four years. In the U.K., four coal power units were operating on Tuesday with as much as 1.5 gigawatts of hourly output being sent across the channel.
The power crisis is so severe that the French government has asked EDF to restart some nuclear reactors earlier than planned amid outage risks for nuclear-powered France. Ecology Minister Barbara Pompili said last weekend that, in addition to the early reactor restarts and past river-temperature limits, the country had contracts with some companies in which they agreed to cut production during peak demand hours in exchange for payments from the government.
Higher energy prices threaten to derail Europe’s economic recovery just as the coronavirus omicron variety is spreading. Trafigura Group’s Nyrstar will pause production at its zinc smelter in France in the first week of January because of rising electricity prices. Norwegian fertilizer producer Yara International, which curbed output earlier this year, said it would continue to monitor the situation closely and curtail production where necessary.
Freezing weather this week is also sending short-term power prices surging as renewables can’t keep up, even though wind and solar overtook gas in the EU last year. German wind output plunged to a five-week low on Tuesday.
CCUS in the U.S. Power Sector drives investments as DOE grants, 45Q tax credits, and EPA carbon rules spur carbon capture, geologic storage, and utilization, while debates persist over costs, transparency, reliability, and emissions safeguards.
Key Points
CCUS captures CO2 from power plants for storage or use, backed by 45Q tax credits, DOE funding, and EPA carbon rules.
✅ DOE grants and 45Q credits aim to de-risk project economics.
✅ EPA rules may require capture rates to meet emissions limits.
✅ Transparency and MRV guard against tax credit abuse.
New public and private funding, including DOE $110M for CCUS announced recently, and expected strong federal power plant emissions reduction standards have accelerated electricity sector investments in carbon capture, utilization and storage,’ or CCUS, projects but some worry it is good money thrown after bad.
CCUS separates carbon from a fossil fuel-burning power plant’s exhaust through carbon capture methods for geologic storage or use in industrial and other applications, according to the Department of Energy. Fossil fuel industry giants like Calpine and Chevron are looking to take advantage of new federal tax credits and grant funding for CCUS to manage potentially high costs in meeting power plant performance requirements, amid growing investor pressure for climate reporting, including new rules, expected from EPA soon, on reducing greenhouse gas emissions from existing power plants.
Power companies have “ambitious plans” to add CCUS to power plants, estimated to cause 25% of U.S. CO2 emissions. As a result, the power sector “needs CCUS in its toolkit,” said DOE Office of Fossil Energy and Carbon Management Assistant Secretary Brad Crabtree. Successful pilots and demonstrations “will add to investor confidence and lead to more deployment” to provide dispatchable clean energy, including emerging CO2-to-electricity approaches for power system reliability after 2030,| he added.
But environmentalists and others insist potentially cost-prohibitive CCUS infrastructure, including CO2 storage hub initiatives, must still prove itself effective under rigorous and transparent federal oversight.
“The vast majority of long-term U.S. power sector needs can be met without fossil generation, and better options are being deployed and in development,” Sierra Club Senior Advisor, Strategic Research and Development, Jeremy Fisher, said, pointing to carbon-free electricity investments gaining momentum in the market. CCUS “may be needed, but without better guardrails, power sector abuses of federal funding could lead to increased emissions and stranded fossil assets,” he added.
New DOE CCUS project grants, an increased $85 per metric ton, or tonne, federal 45Q tax credit, and the forthcoming EPA power plant carbon rules and the federal coal plan will do for CCUS what similar policies did for renewables, advocates and opponents agreed. But controversial past CCUS performance and tax credit abuses must be avoided with transparent reporting requirements for CO2 capture, opponents added.
Nighttime Thermoelectric Generator converts radiative cooling into renewable energy, leveraging outer space cold; a Stanford-UCLA prototype complements solar, serving off-grid loads with low-power output during peak evening demand, using simple materials on a rooftop.
Key Points
A device converting nighttime radiative cooling into electricity, complementing solar for low-power evening needs.
✅ Uses thermocouples to convert temperature gradients to voltage.
✅ Exploits radiative cooling to outer space for night power.
✅ Complements solar; low-cost parts suit off-grid applications.
Two years ago, one freezing December night on a California rooftop, a tiny light shone weakly with a little help from the freezing night air. It wasn't a very bright glow. But it was enough to demonstrate the possibility of generating renewable power after the Sun goes down.
Working with Stanford University engineers Wei Li and Shanhui Fan, University of California Los Angeles materials scientist Aaswath Raman put together a device that produces a voltage by channelling the day's residual warmth into cooling air, effectively generating electricity from thin air with passive heat exchange.
"Our work highlights the many remaining opportunities for energy by taking advantage of the cold of outer space as a renewable energy resource," says Raman.
"We think this forms the basis of a complementary technology to solar. While the power output will always be substantially lower, it can operate at hours when solar cells cannot."
For all the merits of solar energy, it's just not a 24-7 source of power, although research into nighttime solar cells suggests new possibilities for after-dark generation. Sure, we can store it in a giant battery or use it to pump water up into a reservoir for later, but until we have more economical solutions, nighttime is going to be a quiet time for renewable solar power.
Most of us return home from work as the Sun is setting, and that's when energy demands spike to meet our needs for heating, cooking, entertaining, and lighting.
Unfortunately, we often turn to fossil fuels to make up the shortfall. For those living off the grid, it could require limiting options and going without a few luxuries.
Shanhui Fan understands the need for a night time renewable power source well. He's worked on a number of similar devices, including carbon nanotube generators that scavenge ambient energy, and a recent piece of technology that flipped photovoltaics on its head by squeezing electricity from the glow of heat radiating out of the planet's Sun-warmed surface.
While that clever item relied on the optical qualities of a warm object, this alternative device makes use of the good old thermoelectric effect, similar to thin-film waste-heat harvesting approaches now explored.
Using a material called a thermocouple, engineers can convert a change in temperature into a difference in voltage, effectively turning thermal energy into electricity with a measurable voltage. This demands something relatively toasty on one side and a place for that heat energy to escape to on the other.
The theory is the easy part – the real challenge is in arranging the right thermoelectric materials in such a way that they'll generate a voltage from our cooling surrounds that makes it worthwhile.
To keep costs down, the team used simple, off-the-shelf items that pretty much any of us could easily get our hands on.
They put together a cheap thermoelectric generator and linked it with a black aluminium disk to shed heat in the night air as it faced the sky. The generator was placed inside a polystyrene enclosure sealed with a window transparent to infrared light, and linked to a single tiny LED.
For six hours one evening, the box was left to cool on a roof-top in Stanford as the temperature fell just below freezing. As the heat flowed from the ground into the sky, the small generator produced just enough current to make the light flicker to life.
At its best, the device generated around 0.8 milliwatts of power, corresponding to 25 milliwatts of power per square metre.
That might just be enough to keep a hearing aid working. String several together and you might just be able to keep your cat amused with a simple laser pointer. So we're not talking massive amounts of power.
But as far as prototypes go, it's a fantastic starting point. The team suggests that with the right tweaks and the right conditions, 500 milliwatts per square metre isn't out of the question.
"Beyond lighting, we believe this could be a broadly enabling approach to power generation suitable for remote locations, and anywhere where power generation at night is needed," says Raman.
While we search for big, bright ideas to drive the revolution for renewables, it's important to make sure we don't let the smaller, simpler solutions like these slip away quietly into the night.
California Duck Curve highlights midday solar oversupply and steep evening peak demand, stressing grid stability. Solutions include battery storage, demand response, diverse renewables like wind, geothermal, nuclear, and regional integration to reduce curtailment.
Key Points
A mismatch between midday solar surplus and evening demand spikes, straining the grid without storage and flexibility.
✅ Midday solar oversupply forces curtailment and wasted clean energy.
✅ Evening ramps require fast, fossil peaker plants to stabilize load.
✅ Batteries, demand response, regional trading flatten the curve.
California's remarkable success in adopting solar power, including a near-100% renewable milestone, has created a unique challenge: managing the infamous "duck curve." This distinctive curve illustrates a growing mismatch between solar electricity generation and the state's energy demands, creating potential problems for grid stability and ultimately threatening to slow California's progress in the fight against climate change.
The Shape of the Problem
The duck curve arises from a combination of high solar energy production during midday hours and surging energy demand in the late afternoon and evening when solar power declines. During peak solar hours, the grid often has an overabundance of electricity, and curtailments are increasing as a result, while as the sun sets, demand surges when people return home and businesses ramp up operations. California's energy grid operators must scramble to make up this difference, often relying on fast-acting but less environmentally friendly power sources.
The Consequences of the Duck Curve
The increasing severity of the duck curve has several potential consequences for California:
Grid Strain: The rapid ramp-up of power sources to meet evening demand puts significant strain on the electrical grid. This can lead to higher operational costs and potentially increase the risk of blackouts during peak demand times.
Curtailed Energy: To avoid overloading the grid, operators may sometimes have to curtail excess solar energy during midday, as rising curtailment reports indicate, essentially wasting clean electricity that could have been used to displace fossil fuel generation.
Obstacle to More Solar: The duck curve can make it harder to add new solar capacity, as seen in Alberta's solar expansion challenges, for fear of further destabilizing the grid and increasing the need for fossil fuel-based peaking plants.
Addressing the Challenge
California is actively seeking solutions to mitigate the duck curve, aligning with national decarbonization pathways that emphasize practicality. Potential strategies include:
Energy Storage: Deploying large-scale battery storage can help soak up excess solar electricity during the day and release it later when demand peaks, smoothing out the duck curve.
Demand Flexibility: Encouraging consumers to shift their energy use to off-peak hours through incentives and smart grid technologies can help reduce late-afternoon surges in demand.
Diverse Power Sources: While solar is crucial, a balanced mix of energy sources, including geothermal, wind, and nuclear, can improve grid stability and reduce reliance on rapid-response fossil fuel plants.
Regional Cooperation: Integrating California's grid with neighboring states can aid in balancing energy supply and demand across a wider geographical area.
The Ongoing Solar Debate
The duck curve has become a central point of debate about the future of California's energy landscape. While acknowledging the challenge, solar advocates argue for continued expansion, backed by measures like a bill to require solar on new buildings, emphasizing the urgent need to transition away from fossil fuels. Grid operators and some utility companies call for a more cautious approach, emphasizing grid reliability and potential costs if the problem isn't effectively managed.
Balancing California's Needs and its Green Ambitions
Finding the right path forward is essential; it will determine whether California can continue to lead the way in solar energy adoption while ensuring a reliable and affordable electricity supply. Successfully navigating the duck curve will require innovation, collaboration, and a strong commitment to building a sustainable energy system, as wildfire smoke impacts on solar continue to challenge generation predictability.
Illinois Zero Emission Credits support nuclear plants via tradable credits tied to wholesale electricity prices, carbon costs, created by the Future Energy Jobs Bill to avert Exelon closures and sustain low-carbon power.
Key Points
State credits that value nuclear power's zero-carbon output, priced by market and carbon metrics to keep plants running.
✅ Pegged to wholesale prices, carbon costs, and state averages.
✅ Created by Future Energy Jobs Bill to prevent plant retirements.
✅ Supports Exelon Quad Cities and Clinton nuclear facilities.
Nuclear plants have produced over half of Illinois electricity generation since 2010, but the states two largest plants would have been retired amid the debate over saving nuclear plants if the state had not created a zero emission credit (ZEC) mechanism to support the facilities.
The two plants, Quad Cities and Clinton, collectively delivered more than 12 percent of the states electricity generation over the past several years. In May 2016, however, Exelon, the owner of the plants, announced that they had together lost over $800 million dollars over the previous six years and revealed plans to retire them in 2017 and 2018, similar to the Three Mile Island closure later announced for 2019 by its owner.
In December 2016, Illinois passed the Future Energy Jobs Bill, which established a zero emission credit (ZEC) mechanism
to support the plants financially. Exelon then cancelled its plans to retire the two facilities.
The ZEC is a tradable credit that represents the environmental attributes of one megawatt-hour of energy produced from the states nuclear plants. Its price is based on a number of factors that include wholesale electricity market prices, nuclear generation costs, state average market prices, and estimated costs of the long-term effects of carbon dioxide emissions.
The bill is set to take effect in June, but faces multiple court challenges as some utilities have expressed concerns that the ZEC violates the commerce clause and affects federal authority to regulate wholesale energy prices, amid gas-fired competition in nearby markets that shapes the revenue outlook.
Illinois ranks first in the United States for both generating capacity and net electricity generation from nuclear power, a resource many see as essential for net-zero emissions goals, and accounts for approximately one-eighth of the nuclear power generation in the nation.
