With already volatile fuel costs spiking to record heights in the last few days, the Knoxville Utilities Board (KUB) hopes its recent purchase of a more economical, environmentally friendly - and safer - hybrid bucket truck will offer some relief to business costs.

KUB just received its first hybrid bucket truck, which decreases particulate emissions by 96 percent and travels 57 percent farther on a gallon of fuel.

"KUB is working hard to be a good steward of the environment and the purchase of the hybrid bucket truck is one of our many efforts towards environmental stewardship," said Grace Whiteside, KUB business management associate.

Whiteside said the hybrid vehicle gets 7.5 miles per gallon compared to 5.5 miles per gallon for the conventional bucket truck. The hybrid truck also saves money because it doesn't use fuel while idling.

She said the hybrid bucket truck cost $198,000 - or $48,000 more than the conventional truck.

"The cost of the hybrid truck is $48,000 more, but the fuel-cost savings are about $6,000 per year," said Whiteside of the truck that is expected to be in service for 12 years.

Steve Noe, KUB's manager of overhead construction, said the hybrid vehicle has other benefits.

"We are very excited about the new hybrid truck and its performance compared to our existing bucket trucks," said Noe.

"Our line workers are very pleased with the truck and the lack of noise while on the job site. The improved ability to communicate from the bucket to the ground offers the entire crew a much safer working environment."

Whiteside said KUB has 56 bucket trucks in its fleet and the recent hybrid vehicle purchase is being used as a test model.

"This is an experiment," Whiteside said. "We're just trying to see if it saves money. We hope to add more in the future, but there's a long lead time of around two years to purchase hybrid bucket trucks."

Whiteside said KUB has three conventional bucket trucks on order because of the backlog to order the hybrid vehicles.

According to Whiteside, all of KUB's fleet of almost 550 vehicles are powered by biodiesel, hybrid electric, compressed natural gas, E-10 ethanol or E-85 ethanol.

Coal, Business Interests Support EPA in Legal Challenge to Affordable Clean Energy Rule

Affordable Clean Energy Rule Lawsuit pits EPA and coal industry allies against health groups over Clean Power Plan repeal, greenhouse gas emissions standards, climate change, public health, and state authority before the D.C. Circuit.

 

Key Points

A legal fight over EPA's ACE rule and CPP repeal, weighing emissions policy, state authority, climate, and public health.

✅ Challenges repeal of Clean Power Plan and adoption of ACE.

✅ EPA backed by coal, utilities; health groups seek stricter limits.

✅ D.C. Circuit to review emissions authority and state roles.

 

The largest trade association representing coal interests in the country has joined other business and electric utility groups in siding with the EPA in a lawsuit challenging the Trump administration's repeal of the Clean Power Plan.

The suit -- filed by the American Lung Association and the American Public Health Association -- seeks to force the U.S. Environmental Protection Agency to drop a new rule-making process that critics claim would allow higher levels of greenhouse gas emissions, further contributing to the climate crisis and negatively impacting public health.

The new rule, which the Trump administration calls the "Affordable Clean Energy rule" (ACE), "would replace the 2015 Clean Power Plan, which EPA has proposed to repeal because it exceeded EPA's authority. The Clean Power Plan was stayed by the U.S. Supreme Court and has never gone into effect," according to an EPA statement.

EPA has also moved to rewrite wastewater limits for coal power plants, signaling a broader rollback of related environmental requirements.

America's Power -- formerly the American Coalition for Clean Coal Electricity -- the U.S. Chamber of Commerce, the National Mining Association, and the National Rural Electric Cooperative Association have filed motions seeking to join the lawsuit. The U.S. Court of Appeals for the District of Columbia Circuit has not yet responded to the motion.

Separately, energy groups warned that President Trump and Energy Secretary Rick Perry were rushing major changes to electricity pricing that could disrupt markets.

"In this rule, the EPA has accomplished what eluded the prior administration: providing a clear, legal pathway to reduce emissions while preserving states' authority over their own grids," Hal Quinn, president and chief executive officer of the mining association, said when the new rule was released last month. "ACE replaces a proposal that was so extreme that the Supreme Court issued an unprecedented stay of the proposal, having recognized the economic havoc the mere suggestion of such overreach was causing in the nation's power grid."

Around the same time, a coal industry CEO blasted a federal agency's decision on the power grid as harmful to reliability.

The trade and business groups have argued that the Clean Power Plan, set by the Obama administration, was an overreach of federal power. Finalized in 2015, the plan was President Obama's signature policy on climate change, rooted in compliance with the Paris Climate Treaty. It would have set state limits on emissions from existing power plants but gave wide latitude for meeting goals, such as allowing plant operators to switch from coal to other electric generating sources to meet targets.

Former EPA Administrator Scott Pruitt argued that the rule exceeded federal statutory limits by imposing "outside the fence" regulations on coal-fired plants instead of regulating "inside the fence" operations that can improve efficiency.

The Clean Power Plan set a goal of reducing carbon emissions from power generators by 32 percent by the year 2030. An analysis from the Rhodium Group found that had states taken full advantage of the CPP's flexibility, emissions would have been reduced by as much as 72 million metric tons per year on average. Still, even absent federal mandates, the group noted that states are taking it upon themselves to enact emission-reducing plans based on market forces.

In its motion, America's Power argues the EPA "acknowledged that the [Best System of Emission Reduction] for a source category must be 'limited to measures that can be implemented ... by the sources themselves.'" If plants couldn't take action, compliance with the new rule would require the owners or operators to buy emission rate credits that would increase investment in electricity from gas-fired or renewable sources. The increase in operating costs plus federal efforts to shift power generation to other sources of energy, thereby increasing costs, would eventually force the coal-fired plants out of business.

In related proceedings, renewable energy advocates told FERC that a DOE proposal to subsidize coal and nuclear plants was unsupported by the record, highlighting concerns about market distortions.

"While we are confident that EPA will prevail in the courts, we also want to help EPA defend the new rule against others who prefer extreme regulation," said Michelle Bloodworth, president and CEO of America's Power.

"Extreme regulation" to one group is environmental and health protections to another, though.

Howard A. Learner, executive director of the Environmental Law & Policy Center of the Midwest, defended the Clean Power Plan in an opinion piece published in June.

"The Midwest still produces more electricity from coal plants than any other region of the country, and Midwesterners bear the full range of pollution harms to public health, the Great Lakes, and overall environmental quality," Learner wrote. "The new [Affordable Clean Energy] Rule is a misguided policy, moves our nation backward in solving climate change problems, and misses opportunities for economic growth and innovation in the global shift to renewable energy. If not reversed by the courts, as it should be, the next administration will have the challenge of doing the right thing for public health, the climate and our clean energy future."

When it initially filed its lawsuit against the Trump administration's Affordable Clean Energy Rule, the American Lung Association accused the EPA of "abdicat[ing] its legal duties and obligations to protect public health." It also referred to the new rule as "dangerous."

California Legislators Prepare Vote to Crack Down on Utility Spending

California Utility Spending Bill scrutinizes how ratepayer funds are used by utilities, targeting lobbying, advertising, wildfire prevention cost pass-throughs, and CPUC oversight to curb high electricity bills and increase accountability and transparency statewide.

 

Key Points

Legislation restricting utilities from using ratepayer money for lobbying and ads, with stronger CPUC oversight.

✅ Bans ratepayer-funded lobbying and political advertising

✅ Expands prohibited utility communications and influence spending

✅ Aims to curb bills, boost transparency, and CPUC accountability

 

California's legislators are about to vote on a bill that would impose stricter regulations on how utility companies spend the money they collect from ratepayers. This legislation directly responds to the growing discontent among Californians who are already grappling with high electricity bills, as Californians ask why electricity prices are soaring amid wildfire prevention efforts.

Consumer rights groups have been vehemently critical of how utilities have been allocating customer funds, amid growing calls for regulatory action from state officials. They allege that a substantial portion of this money is being funnelled into lobbying efforts and advertising campaigns that yield no direct benefits for the customers themselves.

The proposed bill would significantly broaden the definition of what constitutes prohibited advertising and political influence activities on the part of utility companies, separate from income-based fixed electricity charges proposals that affect rate design. This would effectively restrict the ways in which utilities can utilize customer funds for such purposes.

While consumer advocacy groups have favored the legislation, it has drawn opposition from utility companies and some labor unions, as lawmakers weigh overturning income-based utility charges in parallel debates. Opponents contend that it would hinder utilities' ability to communicate effectively with their customers and advocate for their interests. Additionally, they express concerns that the bill could result in job losses within the utility sector.

The vote on the bill is expected to take place on Monday. The outcome of the vote is uncertain, but it is sure to be a closely watched development for Californians struggling with the burden of high electricity bills, with many wondering about major changes to their electric bills in the near term.

 

California's Electricity Rates: A Burden for Residents

A recent report by the California Public Utilities Commission (CPUC) revealed that the average Californian household spends a significantly higher amount on electricity compared to the national average. This disparity in electricity rates can be attributed to a number of factors, including the financial costs associated with wildfire prevention measures, investments in renewable energy infrastructure, and maintenance of aging electrical grids, even as the state considers revamping electricity rates to clean the grid.

 

Examples of Utility Company Spending that Raise Concerns

Consumer rights groups have specifically highlighted instances where utility companies have used customer money to fund lavish executive compensation packages, sponsor professional sports teams, and finance political campaigns. They argue that these expenditures do not provide any tangible benefits to ratepayers and should not be funded through customer bills.

 

The Need for Accountability and Prioritization

Proponents of the bill believe that the legislation is necessary to ensure that utility companies are held accountable for how they spend customer funds. They believe that the stricter regulations would compel utilities to prioritize investments that directly improve the quality and reliability of electricity services for Californians, alongside discussions of income-based flat-fee utility bills that could reshape rate structures.

The impending vote on the bill underscores the ongoing tension between the need for reliable electricity services and the desire to keep utility rates affordable for Californians. The outcome of the vote is likely to have a significant impact on how utility companies operate in the state and how much Californians pay for their electricity.

Swiss Earthquake Service and ETH Zurich aim to make geothermal energy safer

Advanced Traffic Light System for Geothermal Safety models fracture growth and friction with rock physics, geophones, and supercomputers to predict induced seismicity during hydraulic stimulation, enabling real-time risk control for ETH Zurich and SED.

 

Key Points

ATLS uses rock physics, geophones, and HPC to forecast induced seismicity in real time during geothermal stimulation.

✅ Real-time seismic risk forecasts during hydraulic stimulation

✅ Uses rock physics, friction, and fracture modeling on HPC

✅ Supports ETH Zurich and SED field tests in Iceland and Bedretto

 

The Swiss Earthquake Service and ETH Zurich want to make geothermal energy safer, so news piece from Switzerland earlier this month. This is to be made possible by new software, including machine learning, and the computing power of supercomputers. The first geothermal tests have already been carried out in Iceland, and more will follow in the Bedretto laboratory.

In areas with volcanic activity, the conditions for operating geothermal plants are ideal. In Iceland, the Hellisheidi power plant makes an important contribution to sustainable energy use, alongside innovations like electricity from snow in cold regions.

Deep geothermal energy still has potential. This is the basis of the 2050 energy strategy. While the inexhaustible source of energy in volcanically active areas along fault zones of the earth’s crust can be tapped with comparatively little effort and, where viable, HVDC transmission used to move power to demand centers, access on the continents is often much more difficult and risky. Because the geology of Switzerland creates conditions that are more difficult for sustainable energy production.

Improve the water permeability of the rock

On one hand, you have to drill four to five kilometers deep to reach the correspondingly heated layers of earth in Switzerland. It is only at this depth that temperatures between 160 and 180 degrees Celsius can be reached, which is necessary for an economically usable water cycle. On the other hand, the problem of low permeability arises with rock at these depths. “We need a permeability of at least 10 millidarcy, but you can typically only find a thousandth of this value at a depth of four to five kilometers,” says Thomas Driesner, professor at the Institute of Geochemistry and Petrology at ETH Zurich.

In order to improve the permeability, water is pumped into the subsurface using the so-called “fracture”. The water acts against friction, any fracture surfaces shift against each other and tensions are released. This hydraulic stimulation expands fractures in the rock so that the water can circulate in the hot crust. The fractures in the earth’s crust originate from tectonic tensions, caused in Switzerland by the Adriatic plate, which moves northwards and presses against the Eurasian plate.

In addition to geothermal energy, the “Advanced Traffic Light System” could also be used in underground construction or in construction projects for the storage of carbon dioxide.

Quake due to water injection

The disadvantage of such hydraulic stimulations are vibrations, which are often so weak or cannot be perceived without measuring instruments. But that was not the case with the geothermal projects in St. Gallen 2013 and Basel 2016. A total of around 11,000 cubic meters of water were pumped into the borehole in Basel, causing the pressure to rise. Using statistical surveys, the magnitudes 2.4 and 2.9 defined two limit values ??for the maximum permitted magnitude of the earthquakes generated. If these are reached, the water supply is stopped.

In Basel, however, there was a series of vibrations after a loud bang, with a time delay there were stronger earthquakes, which startled the residents. In both cities, earthquakes with a magnitude greater than 3 have been recorded. Since then it has been clear that reaching threshold values ??determines the stop of the water discharge, but this does not guarantee safety during the actual drilling process.

Simulation during stimulation

The Swiss Seismological Service SED and the ETH Zurich are now pursuing a new approach that can be used to predict in real time, building on advances by electricity prediction specialists in Europe, during a hydraulic stimulation whether noticeable earthquakes are expected in the further course. This is to be made possible by the so-called “Advanced Traffic Light System” based on rock physics, a software developed by the SED, which carries out the analysis on a high-performance computer.

Geophones measure the ground vibrations around the borehole, which serve as indicators for the probability of noticeable earthquakes. The supercomputer then runs through millions of possible scenarios, similar to algorithms to prevent power blackouts during ransomware attacks, based on the number and type of fractures to be expected, the friction and tensions in the rock. Finally, you can filter out the scenario that best reflects the underground.

Further tests in the mountain

However, research is currently still lacking any real test facility for the system, because incorrect measurements must be eliminated and a certain data format adhered to before the calculations on the supercomputer. The first tests were carried out in Iceland last year, with more to follow in the Bedretto geothermal laboratory in late summer, where reliable backup power from fuel cell solutions can keep instrumentation running. An optimum can now be found between increasing the permeability of rock layers and an adequate water supply.

The new approach could make geothermal energy safer and ultimately help this energy source to become more accepted, while grid upgrades like superconducting cables improve efficiency. Research also sees areas of application wherever artificially caused earthquakes can occur, such as in underground mining or in the storage of carbon dioxide underground.

Hydro One launches Ultra-Low Overnight Electricity Price Plan

Ultra-Low Overnight Price Plan delivers flexible electricity pricing from Hydro One and the Ontario Energy Board, with TOU, tiered options, off-peak EV charging savings, balanced billing, and an online calculator to optimize bills.

 

Key Points

An Ontario pricing option with ultra-low night rates, helping Hydro One customers save by shifting usage to off-peak.

✅ Four periods with ultra-low overnight rate for EV charging

✅ Compare TOU vs tiered with Hydro One's online calculator

✅ Balanced billing and due date choice support budget control

 

Hydro One has announced that customers have even more choice and flexibility when it comes to how they are billed for electricity with the company's launch of the Ontario Energy Board's new Ultra-Low Overnight Electricity Price Plan for customers. A new survey of Ontario customers, conducted by Innovative Research Group, shows that 74 per cent of Ontarians find having choice between electricity pricing plans useful.

"As their trusted energy advisor, we want our customers to know we have the insights and tools to help them make the right choice when it comes to their electricity plans," said Teri French, Executive Vice President, Safety, Operations and Customer Experience. "We know that choice and flexibility are important to our customers, and we are proud to now offer them a third option so they can select the plan that best fits their lifestyle."

The same survey revealed that fewer than half of Ontarians are familiar with either tiered or the new ultra-low overnight price plans. To better support its customers Hydro One is providing an online calculator to help them choose which pricing plan best suits their lifestyle. The company also offers additional flexibility and assistance in managing household budgets by providing customers with the ability to choose their billing due date and flatten usage spikes from temperature fluctuations through balanced billing.

During the pandemic, Ontario introduced electricity relief to support families, small businesses and farms, complementing these customer options.

"By offering families and small businesses more choice, we are putting them back in control of their energy bills," said Todd Smith, Minister of Energy. "Starting today Hydro One customers have a new option - the Ultra-Low Electricity Price Plan - which could help them save money each year, while making our province's grid more efficient."

Electricity price plan options

  • New Ultra-Low Overnight price plan (ULO): Designed for customers who use more electricity at night, such as those who charge their electric vehicle, this new price plan can help customers keep costs down and take control of their electricity bill by shifting usage to the ultra-low overnight price period and related off-peak electricity rates when province-wide electricity demand is lower.
  • This plan has four price periods that are the same in the summer as they are in the winter and includes an ultra-low overnight rate.
  • Time-of-Use price plan (TOU): TOU provides customers with more control over their electricity bill by adjusting their usage habits with time-of-use rates used in other jurisdictions as well.
  • In this plan, electricity prices change throughout each weekday, when demand is on-peak, and peak hydro rates can affect overall costs.
  • Tiered price plan (RPP): Tiered pricing provides customers with the flexibility to use electricity at any time of day at the same low price up until the threshold is exceeded during the month, after that usage is charged at a higher price.
  • For residential customers, the winter period (November 1 – April 30) threshold is 1,000 kWh per month and the summer period (May 1 – October 31) threshold is 600 kWh per month. 
  • For small business customers, the threshold is 750 kWh throughout the year, while broader stable electricity pricing supports industrial and commercial companies.

Tens of Thousands Left Without Power as 'Bomb Cyclone' Strikes B.C. Coast

British Columbia Bomb Cyclone disrupts coastal travel with severe wind gusts, heavy rainfall, widespread power outages, ferry cancellations, flooding, and landslides across Vancouver Island, straining emergency services and transport networks during the early holiday season.

 

Key Points

A rapidly intensifying storm hitting B.C.'s coast, causing damaging winds, heavy rain, power outages, and ferry delays.

✅ Wind gusts over 100 km/h and well above normal rainfall

✅ Power outages, flooded roads, and downed trees across the coast

✅ Ferry cancellations isolating communities and delaying supplies

 

A powerful storm, dubbed a "bomb cyclone," recently struck the British Columbia coast, wreaking havoc across the region. This intense weather system led to widespread disruptions, including power outages affecting tens of thousands of residents and the cancellation of ferry services, crucial for travel between coastal communities. The bomb cyclone is characterized by a rapid drop in pressure, resulting in extremely strong winds and heavy rainfall. These conditions caused significant damage, particularly along the coast and on Vancouver Island, where flooding and landslides led to fallen trees blocking roads, further complicating recovery efforts.

The storm's ferocity was especially felt in coastal areas, where wind gusts reached over 100 km/h, and rainfall totals were well above normal. The Vancouver region, already susceptible to storms during the winter months, faced dangerous conditions as power lines were downed, and transportation networks struggled to stay operational. Emergency services were stretched thin, responding to multiple weather-related incidents, including fallen trees, damaged infrastructure, and local flooding.

The ferry cancellations further isolated communities, especially those dependent on these services for essential supplies and travel. With many ferry routes out of service, residents had to rely on alternative transportation methods, which were often limited. The storm's timing, close to the start of the holiday season, also created additional challenges for those trying to make travel arrangements for family visits and other festive activities.

As cleanup efforts got underway, authorities warned that recovery would take time, particularly due to the volume of downed trees and debris. Crews worked to restore power and clear roads, while local governments urged people to stay indoors and avoid unnecessary travel, and BC Hydro's winter payment plan provided billing relief during outages. For those without power, the storm brought cold temperatures, and record electricity demand in 2021 showed how cold snaps strain the grid, making it crucial for families to find warmth and supplies.

In the aftermath of the bomb cyclone, experts highlighted the increasing frequency of such extreme weather events, driven in part by climate change and prolonged drought across the province. With the potential for more intense storms in the future, the region must be better prepared for these rapid weather shifts. Authorities are now focused on bolstering infrastructure to withstand such events, as all-time high demand has strained the grid recently, and improving early warning systems to give communities more time to prepare.

In the coming weeks, as British Columbia continues to recover, lessons learned from this storm will inform future responses to similar weather systems. For now, residents are advised to remain vigilant and prepared for any additional weather challenges, with recent blizzard and extreme cold in Alberta illustrating how conditions can deteriorate quickly.

India's electricity demand falls at the fastest pace in at least 12 years

India Industrial Output Slowdown deepens as power demand slumps, IIP contracts, and electricity, manufacturing, and mining weaken; capital goods plunge while RBI rate cuts struggle to lift GDP growth, infrastructure, and fuel demand.

 

Key Points

A downturn where IIP contracts as power demand, manufacturing, mining, and capital goods fall despite RBI rate cuts.

✅ IIP fell 4.3% in Sep, worst since Feb 2013.

✅ Power demand dropped for a third month, signaling weak industry.

✅ Capital goods output plunged 20.7%, highlighting weak investment.

 

India's power demand fell at the fastest pace in at least 12 years in October, signalling a continued decline in the industrial output, mirroring how China's power demand dropped when plants were shuttered, according to government data. Electricity has about 8% weighting in the country's index for industrial production.

India needs electricity to fuel its expanding economy and has at times rationed coal supplies when demand surged, but a third decline in power consumption in as many months points to tapering industrial activity in a nation that aims to become a $5 trillion economy by 2024.

India's industrial output fell at the fastest pace in over six years in September, adding to a series of weak indicators that suggests that the country’s economic slowdown is deep-rooted and interest rate cuts alone may not be enough to revive growth.

Annual industrial output contracted 4.3% in September, government data showed on Monday. It was the worst performance since a 4.4% contraction in February 2013, according to Refinitiv data.

Analysts polled by Reuters had forecast industrial output to fall 2% for the month.

“A contraction of industrial production by 4.3% in September is serious and indicative of a significant slowdown as both investment and consumption demand have collapsed,” said Rupa Rege Nitsure, chief economist of L&T Finance Holdings.

The industrial output figure is the latest in a series of worrying economic data in Asia's third largest economy, which is also the world's third-largest electricity producer as well.

Economists say that weak series of data could mean economic growth for July-September period will remain near April-June quarter levels of 5%, which was a six-year low, and some analysts argue for rewiring India's electricity to bolster productivity. The Indian government is likely to release April-September economic growth figures by the end of this month.

Subdued inflation and an economic slowdown have prompted the Reserve Bank of India (RBI) to cut interest rates by a total of 135 basis points this year, while coal and electricity shortages eased in recent months.

“These are tough times for the RBI, as it cannot do much about it but there will be pressures on it to act ...Blunt tools like monetary policy may not be effective anymore,” Nitsure said.

Data showed in September mining sector fell 8.5%, while manufacturing and electricity fell 3.9% and 2.6% respectively, even as imported coal volumes rose during April-October. Capital goods output during the month fell 20.7%, indicating sluggish demand.

“IIP (Index of Industrial Production) growth in October 2019 is also likely to be in negative territory and only since November 2019 one can expect mild IIP expansion, said Devendra Kumar Pant, Chief Economist and Senior Director, Public Finance, India Ratings & Research (Fitch Group).

Infrastructure output, which comprises eight main sectors, in September showed a contraction of 5.2%, the worst in 14 years, even as global daily electricity demand fell about 15% during pandemic lockdowns.

India's fuel demand fell to its lowest in more than two years in September, with consumption of diesel to its lowest levels since January 2017. Diesel and gasoline together make up over 7.4% of the IIP weightage.

In 2019/20 India's fuel demand — also seen as an indicator of economic and industrial activity — is expected to post the slowest growth in about six years.
