KUB's board of commissioners considered two proposals meant to help the local utility accommodate TVA efforts to deal with increasing peak power demand, with one plan likely to bring changes to electric bills but with no real change in what customers actually pay, according to KUB officials.

The KUB board approved on first reading a proposal that allows its large industrial customers to take part in a TVA program encouraging them to shift their electric power demand use to non-peak hours.

The board also heard a KUB staff presentation on ways KUB can adjust its retail rate structure to accept changes TVA has approved to its wholesale rate structure. This will involve billing changes that will be complicated for KUB but of little consequence for customers, said Sherri Johnson, manager of rates for KUB.

The board also elected officers for 2011 and swore in Nikitia Thompson to her second term as a KUB commissioner. Pace Robinson was re-elected as chair, Eston Williams was re-elected vice chair and Mark Walker was elected secretary.

Ed Medford, KUB manager of key accounts, told the board that about 11 large industrial customers are eligible to join the Two-Part Real Time Pricing program that TVA has developed. This allows industrial customers to pay a fixed rate for a base level of hourly power use, and any variation in usage is charged or credited to the customer based on TVA's cost of producing the power. Participation by KUB's industrial customers would have no effect on KUB revenues, Medford said. The board approved the proposal after some commissioners received assurances that KUB would not face any hidden costs. The measure will take effect in March if also approved at the February meeting.

Johnson gave the board a presentation on a proposed new retail rate schedule that will come before the board for readings in February and March. Currently, KUB pays TVA a monthly power bill based on the total of power sales to KUB customers and that takes into account both energy and demand at rates that vary by KUB's customer classifications, Johnson said.

Under TVA's new system, KUB would be billed for its total monthly electric use and will be responsible for recovering the appropriate costs from its customers.

Also, TVA's new rate structure will include seasonal rates that will change to reflect higher costs of power generation during the summer. KUB is revising its retail rate structure to accommodate these changes, Johnson said. This includes a proposed increase in basic service charges for residential and small commercial customers to be offset by reductions to these customers' energy rates.

This should allow KUB to accommodate the new TVA rate structure without taking in additional revenue from customers, she said.

The new KUB rate schedule will take effect in May if approved on both readings.

China's Data Centers Alone Will Soon Use More Electricity Than All Of Australia

Cloud Data Centers Environmental Impact highlights massive electricity use, carbon emissions, and cooling demands, with coal-heavy grids in China; big tech shifts to renewable energy, green data centers, and cooler climates to boost sustainability.

 

Key Points

Energy use, emissions, and cooling load of cloud systems, and shifts to renewables to reduce climate impact.

✅ Global data centers use 3-5% of electricity, akin to airlines

✅ Cooling drives energy demand; siting in cool climates saves power

✅ Shift from coal to renewables lowers CO2 and improves PUE

 

A hidden environmental price makes storing data in the cloud a costly convenience.

Between 3 to 5% of all electricity used globally comes from data centers that house massive computer systems, with computing power forecasts warning consumption could climb, an amount comparable to the airline industry, says Ben Brock Johnson, Here & Now’s tech analyst.

Instead of stashing information locally on our own personal devices, the cloud allows users to free up storage space by sending photos and files to data centers via the internet.

The cloud can also use large data sets to solve problems and host innovative technologies that make cities and homes smarter, but storing information at data centers uses energy — a lot of it.

"Ironically, the phrase 'moving everything to the cloud' is a problem for our actual climate right now," Johnson says.

A new study from Greenpeace and North China Electric Power University reports that in five years, China's data centers alone will consume as much power as the total amount used in Australia in 2018. The industry's electricity consumption is set to increase by 66% over that time.

Buildings storing data produced 99 million metric tons of carbon last year in China, the study finds, with SF6 in electrical equipment compounding warming impacts, which is equivalent to 21 million cars.

The amount of electricity required to run a data center is a global problem, but in China, 73% of these data centers run on coal, even as coal-fired electricity is projected to fall globally this year.

The Chinese government started a pilot program for green data centers in 2015, which Johnson says signals the country is thinking about the environmental consequences of the cloud.

"Beijing’s environmental awareness in the last decade has really come from a visible impact of its reliance on fossil fuels," he says. "The smog of Chinese cities is now legendary and super dangerous."

The country's solar power innovations have allowed the country to surpass the U.S. in cleantech, he says.

Chinese conglomerate Alibaba Group has launched data centers powered by solar and hydroelectric power.

"While I don't know how committed the government is necessarily to making data centers run on clean technology," Johnson says. "I do think it is possible that a larger evolution of the government's feelings on environmental responsibility might impact this newer tech sector."

In the U.S., there has been a big push to make data centers more sustainable amid warnings that the electric grid is not designed for mounting climate impacts.

Canada has made notable progress decarbonizing power, with nationwide electricity gains supporting cleaner data workloads.

Apple now says all of its data centers use clean energy. Microsoft is aiming for 70% renewable energy by 2023, aligning with declining power-sector emissions as producers move away from coal.

Amazon is behind the curve, for once, with about 50%, Johnson says. Around 1,000 employees are planning to walk out on Sept. 20 in protest of the company’s failure to address environmental issues.

"Environmental responsibility fits the brand identities these companies want to project," he says. "And as large tech companies become more competitive with each other, as Apple becomes more of a service company and Google becomes a device company, they want to convince users more and more to think of them as somehow different even if they aren't."

Google and Facebook are talking about building data centers in cooler places like Finland and Sweden instead of hot deserts like Nevada, he says.

In Canada, cleaning up electricity is critical to meeting climate pledges, according to recent analysis.

Computer systems heat up and need to be cooled down by air conditioning units, so putting a data center in a warm climate will require greater cooling efforts and use more energy.

In China, 40% of the electricity used at data centers goes toward cooling equipment, according to the study.

The more data centers consolidate, Johnson says they can rely on fewer servers and focus on larger cooling efforts.

But storing data in the cloud isn't the only way tech users are unknowingly using large amounts of energy: One Google search requires an amount of electricity equivalent to powering a 60-watt light bulb for 17 seconds, magazine Yale Environment 360 reports.

"In some ways, we're making strides even as we are creating a bigger problem," he says. "Which is like, humanity's MO, I guess."

Ford announces an all-electric Transit cargo van

Ford Electric Transit is an all electric cargo van for US and Canada, launching 2021, with 4G LTE hotspot, fleet telematics, GPS tracking, and driver assistance safety tech; battery, range, and performance specs TBD.

 

Key Points

An all electric cargo van with fleet telematics, 4G LTE, and driver assistance features for US and Canada.

✅ 4G LTE hotspot, live GPS tracking, and diagnostics

✅ Fleet telematics and management tools for operations

✅ Driver assistance: AEB, lane keeping, and collision warning

 

Ford is making an all-electric version of its popular Transit cargo van for the US and Canadian markets, slated to be released in 2021, aligning with Ford’s EV manufacturing plans to scale production across North America. The company did not share any specifics about the van’s battery pack size, estimated range, or performance characteristics. Ford previously announced an electric Transit for the European market in 2019.

The new cargo van will come equipped with a 4G LTE hotspot and will be outfitted with a number of tech features designed for fleet managers, like live GPS tracking and diagnostics, mirroring moves by Volvo’s electric trucks aimed at connected operations. The electric Transit van will also be equipped with a number of Ford’s safety and driver assistance features, like collision warning and assist, automatic emergency braking, pedestrian detection, and automatic lane-keeping.

Ford said it didn’t have any news to share about an electric version of its Transit passenger van “at this time,” even as the market reaches an EV inflection point for adoption.

Ford’s Transit van is the bestselling cargo van in the US, though it has seen increased competition over the last few years from Mercedes-Benz, which recently refreshed its popular Sprinter van, while others pursue electrified freight like Tesla’s electric truck plans that expand options.

Mercedes-Benz has already unveiled an electric version of the Sprinter, which comes in two configurations, targeting delivery networks where UPS’s Tesla Semi orders signal growing demand. There’s a version with a 55kWh battery pack that can travel 168 kilometers (104 miles) on a full charge, and has a payload capacity of 891 kilograms (1,964 pounds). Mercedes-Benz is making a version with a smaller 41kWh battery pack that goes 115 kilometers (72 miles), but which can carry up to 1,045 (2,304 pounds). Both versions come with 10.5 cubic meters (370.8 cubic feet) of storage space.

Mercedes-Benz also announced the EQV concept a year ago, which is an electric van aimed at slightly more everyday use, reflecting broader people-moving trends as electric bus adoption faces hurdles worldwide. The company touted more promising specs with the slightly smaller EQV, saying it will get around 249 miles out of a 100kWh battery pack. Oh, and it has 200 horsepower on offer and will be equipped with the company’s MBUX infotainment system.

Another player in the space is EV startup Rivian, which will build 100,000 electric delivery vans for Amazon over the next few years. Ford has invested $500 million in Rivian, and the startup is helping build a luxury electric SUV for the automotive giant’s Lincoln brand, though the two van projects don’t seem to be related, as Ford and others also boost gas-electric hybrid strategies in the US. Ford is also collaborating with Volkswagen on commercial vans after the two companies formed a global alliance early last year.

WY Utility's First Wind Farm Faces Replacement

Foote Creek I Wind Farm Repowering upgrades Wyoming turbines with new nacelles, towers, and blades, cutting 68 units to 12 while sustaining 41.6 MW, under PacifiCorp and Rocky Mountain Power's Energy Vision 2020 plan.

 

Key Points

Replacement at Foote Creek Rim I, cutting to 12 turbines while sustaining about 41.6 MW using modern 2-4.2 MW units.

✅ 12 turbines replace 68, output steady near 41.6 MW

✅ New nacelles, towers, blades; taller 500 ft turbines

✅ Part of PacifiCorp Energy Vision 2020 and Gateway West

 

A Wyoming utility company has filed a permit to replace its first wind farm—originally commissioned in 1998, composed of over 65 turbines—amid new gas capacity competing with nuclear in Ohio, located at Foote Creek Rim I. The replacement would downsize the number of turbines to 12, which would still generate roughly the same energy output.

According to the Star Tribune, PacifiCorp’s new installation would involve new nacelles, new towers and new blades. The permit was filed with Carbon County.

 

New WY Wind Farm

The replacement wind turbines will stand more than twice as tall as the old: Those currently installed stand 200 feet tall, whereas their replacements will tower closer to 500 feet. Though this move is part of the company’s overall plan to expand its state wind fleet as some utilities respond to declining coal returns in the Midwest, the work going into the Foote Creek site is somewhat special, noted David Eskelsen, spokesperson for Rocky Mountain Power, the western arm of PacifiCorp.

“Foote Creek I repowering is somewhat different from the repowering projects announced in the (Energy Vision) 2020 initiative,” he said. “Foote Creek is a complete replacement of the existing 68 foundations, towers, turbine nacelles and rotors (blades).”

Currently, the turbines at Foote Creek have 600 kilowatts capacity each; the replacements’ maximum production ranges from 2 megawatts to 4.2 megawatts each, with the total output remaining steady at 41.4 megawatts, a scale similar to a 30-megawatt wind expansion in Eastern Kings, though there will be a slight capacity increase to 41.6 megawatts, according to the Star Tribune.

As part of the wind farm repowering initiative, PacifiCorp is to become full owner and operator of the Foote Creek site. When the farm was originally built, an Oregon-based water and electric board was 21 percent owner; 37 percent of the project’s output was tied into a contract with the Bonneville Power Administration.

Otherwise, PacifiCorp is moving to further expand its state wind fleet in line with initiatives like doubling renewable electricity by 2030 in Saskatchewan, with the addition of three new wind farms—to be located in Carbon, Albany and Converse counties—which may add up to 1,150 megawatts of power.

According to PacifiCorp, the company has more than 1,000 megawatts of owned wind generation capability, along with long-term purchase agreements for more than 600 megawatts from other wind farms owned by other entities. Energy Vision 2020 refers to a $3.5 billion investment and company move that is looking to upgrade the company's existing wind fleet with newer technology, adding 1,150 megawatts of new wind resources by 2020 and a a new 140-mile Gateway West transmission segment in Wyoming, comparable to a transmission project in Missouri just energized.

Ontario pitches support for electric bills

Ontario CEAP Program provides one-time electricity bill relief for residential consumers via local utilities, supports low-income households, aligns with COVID-19 recovery rates, and complements time-of-use pricing options and the winter disconnection ban.

 

Key Points

A one-time electricity bill credit for eligible Ontario households affected by COVID-19, available via local utilities.

✅ Apply through your local distribution company or utility

✅ One-time credit for overdue electricity bills from COVID-19

✅ Complements TOU options, OER, and winter disconnection ban

 

Applications for the CEAP program for Ontario residential consumers has opened. Residential customers across the province can now apply for funding through their local distribution company/utility.

On June 1st, our government announced a suite of initiatives to support Ontario’s electricity consumers amid changes for electricity consumers during the pandemic, including a $9 million investment to support low-income Ontarians through the COVID-19 Energy Assistance Program (CEAP). CEAP will provide a one-time payment to Ontarians who are struggling to pay down overdue electricity bills incurred during the COVID-19 outbreak.

These initiatives include:

  • $9 million for the COVID-19 Energy Assistance Program (CEAP) to support consumers struggling to pay their energy bills during the pandemic. CEAP will provide one-time payments to consumers to help pay down any electricity bill debt incurred over the COVID19 period. Applications will be available through local utilities in the upcoming months;
  • $8 million for the COVID-19 Energy Assistance Program for Small Business (CEAP-SB) to provide support to businesses struggling with bill payments as a result of the outbreak; and
  • An extension of the Ontario Energy Board’s winter disconnection ban until July 31, 2020 to ensure no one is disconnected from their natural gas or electricity service during these uncertain times.


More information about applications for the CEAP for Small Business will be coming later this summer, as electricity rates are about to change across Ontario for many customers.

In addition, the government recently announced that it will continue the suspension of time-of-use (TOU) electricity rates and, starting on June 1, 2020, customers will be billed based on a new fixed COVID-19 hydro rate of 12.8 cents per kilowatt hour. The COVID-19 Recovery Rate, which some warned in analysis could lead to higher hydro bills will be in place until October 31, 2020.

Later in the pandemic, Ontario set electricity rates at the off-peak price until February 7 to provide additional relief.

“Starting November 1, 2020, our government has announced Ontario electricity consumers will have the option to choose between time-of-use and tiered electricity pricing plan, following the Ontario Energy Board’s new rate plan prices and support thresholds announcement. We are proud to soon offer Ontarians the ability to choose an electricity plan that best suits for their lifestyle,” said Jim McDonell, MPP for Stormont–Dundas–South Glengarry.

The government will continue to subsidize electricity bills by 31.8 per cent through the Ontario Electricity Rebate.

The government is providing approximately $5.6 billion in 2020-21 as part of its existing electricity cost relief programs and conservation initiatives such as the Peak Perks program to help ensure more affordable electricity bills for eligible residential, farm and small business consumers.

Solar Becomes #3 Renewable Electricity Source In USA

U.S. Solar Generation 2017 surpassed biomass, delivering 77 million MWh versus 64 million MWh, trailing only hydro and wind; driven by PV expansion, capacity additions, and utility-scale and small-scale growth, per EIA.

 

Key Points

It was the year U.S. solar electricity exceeded biomass, hitting 77 million MWh and trailing only hydro and wind.

✅ Solar: 77 million MWh; Biomass: 64 million MWh (2017, EIA)

✅ PV expansion; late-year capacity additions dampen annual generation

✅ Hydro: 300 and wind: 254 million MWh; solar thermal ~3 million MWh

 

Electricity generation from solar resources in the United States reached 77 million megawatthours (MWh) in 2017, surpassing for the first time annual generation from biomass resources, which generated 64 million MWh in 2017. Among renewable sources, only hydro and wind generated more electricity in 2017, at 300 million MWh and 254 million MWh, respectively. Biomass generating capacity has remained relatively unchanged in recent years, while solar generating capacity has consistently grown.

Annual growth in solar generation often lags annual capacity additions because generating capacity tends to be added late in the year. For example, in 2016, 29% of total utility-scale solar generating capacity additions occurred in December, leaving few days for an installed project to contribute to total annual generation despite being counted in annual generating capacity additions. In 2017, December solar additions accounted for 21% of the annual total. Overall, solar technologies operate at lower annual capacity factors and experience more seasonal variation than biomass technologies.

Biomass electricity generation comes from multiple fuel sources, such as wood solids (68% of total biomass electricity generation in 2017), landfill gas (17%), municipal solid waste (11%), and other biogenic and nonbiogenic materials (4%).These shares of biomass generation have remained relatively constant in recent years, even as renewables' rise in 2020 across the grid.

Solar can be divided into three types: solar thermal, which converts sunlight to steam to produce power; large-scale solar photovoltaic (PV), which uses PV cells to directly produce electricity from sunlight; and small-scale solar, which are PV installations of 1 megawatt or smaller. Generation from solar thermal sources has remained relatively flat in recent years, at about 3 million MWh, even as renewables surpassed coal in 2022 nationwide. The most recent addition of solar thermal capacity was the Crescent Dunes Solar Energy plant installed in Nevada in 2015, and currently no solar thermal generators are under construction in the United States.

Solar photovoltaic systems, however, have consistently grown in recent years, as indicated by 2022 U.S. solar growth metrics across the sector. In 2014, large-scale solar PV systems generated 15 million MWh, and small-scale PV systems generated 11 million MWh. By 2017, annual electricity from those sources had increased to 50 million MWh and 24 million MWh, respectively, with projections that solar could reach 20% by 2050 in the U.S. mix. By the end of 2018, EIA expects an additional 5,067 MW of large-scale PV to come online, according to EIA’s Preliminary Monthly Electric Generator Inventory, with solar and storage momentum expected to accelerate. Information about planned small-scale PV systems (one megawatt and below) is not collected in that survey.

'Unbelievably dangerous': NB Power sounds alarm on copper theft after vandalism, deaths

NB Power copper thefts highlight risks at high-voltage substations, with vandalism, fatalities, infrastructure damage, ratepayer costs, and law enforcement alerts tied to metal prices, stolen electricity, and safety concerns across New Brunswick and Nova Scotia.

 

Key Points

Substation metal thefts causing fatalities, outages, safety risks, and higher costs that impact NB ratepayers.

✅ Spike aligns with copper price near $3 per pound

✅ Fatal break-ins at high-voltage facilities in Bathurst

✅ Repairs, delays, and safety risks for crews, customers

 

New Brunswick's power utility is urging people to stay away from its substations, saying the valuable copper they contain is proving hard to resist for thieves.

NB Power has seen almost as many incidents of theft and vandalism to its property in April and May of this year, than in all of last year.

In the 2018-2019 fiscal year, the utility recorded 16 cases of theft and/or vandalism.

In April and May, there have already been 13 cases.

One of those was a fatal incident in Bathurst. On April 13, a 41-year-old man was found unresponsive and later died, after breaking into a substation. It was the second fatality linked to a break-in at an NB Power facility in 10 years.

The investigation is still ongoing, but NB Power believes the man was trying to steal copper.

The power utility has been ramping up its efforts -- finding alternate ways to secure its properties, and educate the public -- on the dangers of copper theft, as utilities work to adapt to climate change that can exacerbate severe weather.

“We really, really, really want to stress that if you’re hitting the wrong wire, cutting the wrong wire, breaking in to or cutting fences, a lot of very bad things can happen,” said NB Power spokesperson Marc Belliveau.

In the 2017-2018 fiscal year, there were 24 recorded cases of theft and/or vandalism.

It also comes at a financial cost for NB Power, and ratepayers -- on average, $330,000 a year. About two-thirds of that is copper. The rest is vehicle break-ins or stolen electricity.

“We’ve done analysis,” Belliveau said. “Often the number of break-ins correspond with the price spiking in copper. So, right now, copper’s about $3 a pound. If it was half of that, there might be half as many incidents.”

New Brunswick Public Safety Minister Carl Urquhart says he knows the utility and police are working to dissuade people from the dangers of the theft, and notes that debates around Site C dam stability issues reflect broader infrastructure safety concerns.

“We all know of incident after incident of major injuries and death caused by, simply by, copper,” he said.

Last November, a Dawson Settlement substation was targeted during a major, storm-related power outage in the province.

It meant NB Power had to divert crews to fix and secure the substation, delaying restoration times for some residents and underscoring efforts to improve local reliability across the grid.

Belliveau says that’s “most frustrating.”

“We’re really trying to take a more proactive approach. And certainly, we encourage people that if you know somebody who’s thinking of doing something like that, to really try and talk them out of it because it’s unbelievably dangerous to break in to a substation,” he said.

Nova Scotia Power, connected through the Maritime Link, was not able to provide details on thefts at their substations, but spokesman David Rodenhiser said "the value of the stolen copper is minor in comparison to the risk that’s created when thieves break into our high-voltage electrical substations."

It's not just risky for the people breaking in, and public opposition to projects like Site C underscores broader community safety concerns.

"It also puts the safety of the workers who maintain our substations at risk, because when thieves steal copper, the protective safety devices in the substations don’t work properly," Rodenhiser said.

Additionally, in Nova Scotia, projects like the Maritime Link have advanced regional transmission, and Nova Scotia Power’s copper components have identifying markers, which make that copper difficult to fence. Anyone who buys or sells stolen propery is at risk of criminal charges.
