Blackouts skyrocketing in U.S.

Labrador Island Link Reliability faces scrutiny as Nalcor Energy and General Electric address software issues; Liberty Consulting warns of Holyrood risks, winter outages, grid stability concerns, and PUB oversight for Newfoundland and Labrador.

Key Points

It is the expected dependability of the link this winter, currently uncertain due to GE software and Holyrood risks.

✅ GE software delays may hinder reliable in-service by mid-November.

✅ Holyrood performance issues increase winter outage risk.

✅ PUB directs Hydro to plan contingencies and improve assets.

An independent consultant is questioning if the brand new Labrador Island link can be counted on to supply power to Newfoundland this coming winter.

In June, Nalcor Energy confirmed it had successfully sent power from Churchill Falls to the Avalon Peninsula through its more than 1500-kilometre link, but now the Liberty Consulting Group says it doesn't expect the link will be up and running consistently this winter.

"What we have learned supports a conclusion that the Labrador Island Link is unlikely to be reliably in commercial operation at the start of the winter," says the report dated Aug. 30, 2018.

The link relies on software provided by General Electric but Liberty says there are lingering questions about GE's ability to ensure the necessary software will be in place this fall.

"At an August meeting, company representatives did not express confidence in GE's ability to meet an in-service date for the Labrador Island Link of mid-November," says the report.

Liberty also says testing the link for a brief period this spring and fall doesn't demonstrate long-term reliability.

"The link will remain prone to the uncertainties any new major facility faces early in its operating life, especially one involving technology new to the operating company," according to the report.

Holyrood trouble

The report goes on to say island residents should also be worried about the reliability of the troubled Holyrood facility — a facility that's important when demand for energy is high during winter months.

Liberty says "poor performance at the Holyrood thermal generating station increases the risk of outages considerably."

The group's report concludes the deteriorating condition of Holyrood is a major threat to the island's power supply and Liberty says that threat "could produce very severe consequences when the Labrador Island Link is unavailable."

The consultant says questions about the Labrador Island Link's readiness combined with concerns about the reliability of Holyrood may mean power outages, and for vulnerable customers, debates over hydro disconnections policies often intensify during winter.

"This all suggests that, for at least part of this winter, the island interconnected system may be at the mercy of the weather, where severe events can test utilities' storm response efforts further."

The consultant's report also includes five recommendations to the PUB, reflecting the kind of focused nuclear alert investigation follow-up seen elsewhere.

In essence, Liberty is calling for the board to direct Newfoundland and Labrador Hydro to make plans for the possibility that the link won't be available this winter. It's also calling on hydro to do more to improve the reliability of its other assets, such as Holyrood, as some operators have even contemplated locking down key staff to maintain operations during crises.

Response to Liberty's report

Nalcor CEO Stan Marshall defended the Crown corporation's winter preparedness in an email statement to CBC.

"The right level of planning and investment has been made for our existing equipment so we can continue to meet all of our customer electricity needs for this coming winter season," he wrote.

Regarding the Labrador Island Link, Marshall called for patience.

"This is new technology for our province and integrating the new transmission assets into our current electricity system is complex work that takes time," he said.

There is also a more detailed response from Newfoundland and Labrador Hydro which was sent to the province's Public Utiltiies Board.

Hydro says it will keep testing the Labrador Island Link and increasing the megawatts that are wheeled through it. It also says in October it will begin to give the PUB regular reports on the link's anticipated in-service date.

Tucson Electric Power Coal Phaseout advances an Integrated Resource Plan to exit Springerville coal by 2032, lift renewables past 70 percent by 2035, add wind, solar, battery storage, and cut carbon emissions 80 percent.

Key Points

A 2032 coal exit and 2035 plan to lift renewables above 70 percent, add wind, solar, storage, and cut CO2 80 percent.

✅ Coal purchases end at Springerville units by 2032

✅ Renewables exceed 70 percent of load by 2035

✅ 80 percent CO2 cut from 2005 baseline via wind, solar, storage

In a dramatic policy shift, Tucson Electric Power says it will stop using coal to generate electricity by 2032 and will increase renewable energy's share of its energy load to more than 70% by 2035.

As part of that change, the utility will stop buying electricity from its two units at its coal-fired Springerville Generating Station by 2032. The plant, TEP's biggest power source, provides about 35% of its energy.

The utility already had planned to start up two New Mexico wind farms and a solar storage plant in the Tucson area by next year. The new plan calls for adding an additional 2,000 megawatts of renewable energy capacity by 2035.

The utility's switch from fossil fuels is spelled out in the plan, submitted to the Arizona Corporation Commission, amid shifts in federal power plant rules that could affect implementation. Called an Integrated Resource Plan, it would reduce TEP's carbon dioxide emissions 80% by 2035 compared with 2005 levels.

The plan drew generally positive reviews from a number of environmentalists and other representatives of an advisory committee that had worked with TEP for a year.

Two commissioners, Chairman Bob Burns and Tucsonan Lea Marquez Peterson, also generally praised the plan, although they held off on final judgment.

University of Arizona researchers said the plan would likely meet the utility's share of the worldwide goal of holding down global temperatures to less than 2 degrees Celsius, or about 3.6 degrees Fahrenheit, above pre-industrial levels, even as studies find that climate change threatens grid reliability in many regions.

But a representative of AARP and the Pima Council on Aging expressed concern because the plan would require 1% annual electric rate increases a year to put into effect.

Officials in the eastern Arizona town of Springerville aren't happy.

And Sierra Club official Sandy Bahr said the plan doesn't move fast enough to get TEP off coal. She listed 14 separate units of various Western coal-fired plants that are scheduled to shut down sooner than 2032, many in the 2020s.

But TEP says the plan best balances costs and environmental benefits compared with 24 others it reviewed.

"We know our customers want safe, reliable energy from resources that are both affordable and environmentally responsible. TEP's 2020 Integrated Resource Plan will help us maintain that delicate balance," TEP CEO David Hutchens wrote in the forward to the plan.

The plan isn't legally binding but is aimed at sending a signal to regulators and the public about TEP's future direction. TEP and other regulated Arizona utilities update such plans every three years.

TEP has been one of the West's more fossil-fuel-friendly utilities. It stuck with coal even as many other utilities were moving away from it, including Alliant Energy's carbon-neutral plan to cut emissions and costs, and as the Sierra Club called on utilities to move beyond what it termed a highly polluting energy source that emits large quantities of heat-trapping greenhouse gases linked by scientists to global warming.

Last year, TEP got 13% of its electricity from renewables such as wind farms and solar plants along with photovoltaic solar panels atop individual homes. Fossil fuels coal and natural gas supplied the rest, a University of Arizona study paid for by TEP found.

Economics, not just emissions, a big factor

TEP's previous resource plan, from 2017, called for boosting renewable use to 30% by 2030 and to cut coal to 38% of its electric load by then from 69% in 2017, reflecting broader 2017 utility trends across the industry.

A TEP official said last week the utility is heading in a different direction not only due to concerns about greenhouse gas emissions but because of changing economics.

"For the last several decades, coal was the most economical resource. It was the lowest-cost resource to supply energy for our customers, and it wasn't really close," said Jeff Yockey, TEP's resource planning director.

But over the past few years, first natural gas prices and more recently solar and wind energy prices have fallen dramatically, he said.

Their prices are projected to keep falling, along with the cost of battery-fueled storage of solar energy for use when the sun is down, he said.

"Coal just isn't the most economical resource" now, Yockey said.

Yet the utility still needs, for now, the extra energy capacity that coal provides, he said, even as other states outline ways to improve grid reliability through targeted investments.

"Being a utility with no nuclear or hydro(electric) energy, with coal, there is reliability, a fuel on the ground, 30 or 90 days supply," he said. "It's the only source not subject to disruption in the next hour. It's our only long-term, stable fuel supply. Over time, we will be able to overcome that."

UA researchers, community panel worked on plan

TEP paid the UA $100,000 to have three researchers prepare two reports, one comparing 24 different proposals and a second comparing TEP's fossil fuel/renewable split with those of other utilities.

Also, the utility appointed an advisory council representing environmental, business and government interests that met regularly to guide TEP in producing the plan. The utility chose a preferred energy "portfolio," Yockey said.

The goal "was very much about basically achieving significant emissions reductions as quickly as we can and as cost effectively as we can," he said. TEP wanted the biggest cumulative emission cut possible over 15 years.

"If it was just about cost, we wouldn't have selected the portfolio that we selected. It wasn't the lowest cost portfolio."

UA assistant research professors Ben McMahan and Will Holmgren said combined carbon dioxide emission reductions from TEP's new plan over 15 years would be expected to hit the Paris accord's 2-degree target.

"There is considerable uncertainty about what will happen between now and 2050, but the preferred portfolio's early start on reductions and lowest cumulative emissions is certainly a positive sign that well below 2C is achievable," the researchers said in an email.

Environmentalists pleased, but some want coal cut sooner

The Sierra Club, Western Resource Advocates, the Southwest Energy Efficiency Project and Pima County offered varying degrees of praise for the new TEP plan.

In a memo Friday, County Administrator Chuck Huckelberry congratulated TEP for "the comprehensive, inclusive and transparent process" used to develop the plan.

Because of UA's involvement, TEP's advisory council and the public "can feel confident that the utility is on track to make significant progress in curbing greenhouse gas emissions to combat climate change," Huckelberry wrote.

The TEP plan "is the most aggressive commitment to reducing emissions by a utility in Arizona," said Autumn Johnson of Western Resource Advocates in a news release.

"Adding clean energy generation and storage while accelerating the retirement of coal units will ensure a healthier and better future for Arizonans," said Johnson, an energy policy analyst in Phoenix.

The Sierra Club will have a technical expert review the plan and already wants more energy savings, said Bahr, director of the group's Grand Canyon chapter. But overall, this plan is a step in the right direction for TEP, she said.

By comparison, Arizona Public Service's new resource plan only calls for 45% renewable energy by 2030, Bahr noted, while California regulators consider more power plants to ensure reliability. APS committed to going coal-free by 2031.

A Sierra Club proposal that the UA reviewed called for TEP to quit coal by 2027.

But TEP analyzed that proposal and concluded it would require $300 million in investments and would reduce the utility's cumulative emissions by only 2.4 million tons, to 70.2 million tons by 2035, Yockey said.

The Sierra Club plan was the most expensive portfolio investigated, Yockey said.

"The difference is in the timing. We still have a fair amount of value in our coal plants which we need to depreciate, which we do over time," Yockey said. "Trying to replace the capacity that coal provides in the near term with storage and solar is very expensive, although those costs are declining."

Seniors on fixed incomes could be hurt, advocate says

Rene Pina, an advisory council member representing two senior citizen organizations, praised the plan's goals but was concerned about impacts of even 1% annual rate increases on elderly people on fixed incomes.

They can't always handle such an increase, he said.

One possible fix is that TEP could ease eligibility requirements for its low-income energy assistance program, aligning with equity-focused electricity regulation principles, to allow more seniors to benefit, said Pina, representing AARP and the Pima Council on Aging.

"The program is structured so it just barely disqualifies most of our seniors. Their social security pension is just barely over the low-income limit. It can easily be adjusted without any problems to the utility," Pina said.

Advisory council member Rob Lamb, an engineer with GHLN, an architecture-engineering firm, said he was very pleased with TEP's plan.

"One of the things a lot of people don't realize when they put together a plan like that, is they have to balance environment with 'Hey, what's the reliability of service? Are we going to be able to keep our rates for something that will work?'" Lamb said.

"This a very balanced and resilient portfolio."

China Power Demand-Emissions Gap highlights surging grid demand outpacing renewables, with coal filling shortages despite record solar, wind, EV charging, and hydrogen growth, threatening decarbonization targets and net-zero pathways through 2030.

Key Points

China's power demand outpaces renewables, keeping coal dominant and raising emissions risk through the 2020s.

✅ Record solar and wind still lag fast grid demand growth

✅ Coal fills gaps as EV charging and hydrogen loads rise

✅ Forecasts diverge: CEC bullish vs IEA, BNEF conservative

Here’s a new obstacle that could prevent the world finally turning the corner on climate change: Imagine that over the coming decade a whole new economy the size of Russia were to pop up out of nowhere. With the world’s fourth-largest electricity sector and largest burden of power plant emissions after China, the U.S. and India, this new economy on its own would be enough to throw out efforts to halt global warming — especially if it keeps on growing through the 2030s.

That’s the risk inherent in China’s seemingly insatiable appetite for grid power, as surging electricity demand is putting systems under strain worldwide.

From the cracking pace of renewable build-out last year, you might think the country had broken the back of its carbon addiction. A record 55 gigawatts of solar power and 48 gigawatts of wind were connected — comparable to installing the generation capacity of Mexico in less than 12 months. This year will see an even faster pace, with 93 GW of solar and 50 GW of wind added, according to a report last week from the China Electricity Council, an industry association.

That progress could in theory see the country’s power sector emissions peak within months, rather than the late-2020s date the government has hinted at. Combined with a smaller quantity of hydro and nuclear, low-emissions sources will probably add about 310 terawatt-hours to zero-carbon generation this year. That 3.8% increase would be sufficient to power the U.K.

Countries that have reached China’s levels of per-capita electricity consumption (already on a par with most of Europe) typically see growth rates at less than half that level, even as global power demand has surged past pre-pandemic levels in recent years. Grid supply could grow at a faster pace than Brazil, Iran, South Korea or Thailand managed over the past decade without adding a ton of additional carbon to the atmosphere.

There’s a problem with that picture, however. If electricity demand grows at an even more headlong pace, there simply won’t be enough renewables to supply the grid. Fossil fuels, overwhelmingly coal, will fill the gap, a reminder of the iron law of climate dynamics in energy transitions.

Such an outcome looks distinctly possible. Electricity consumption in 2021 grew at an extraordinary rate of 10%, and will increase again by between 5% and 6% this year, according to the CEC. That suggests the country is on pace to match the CEC’s forecasts of bullish grid demand over the coming decade, with generation hitting 11,300 terawatt-hours in 2030. External analysts, such as the International Energy Agency and BloombergNEF, envisage a more modest growth to around 10,000 TWh. 

The difference between those two outlooks is vast — equivalent to all the electricity produced by Russia or Japan. If the CEC is right and the IEA and BloombergNEF are wrong, even the furious rate of renewable installations we’re seeing now won’t be enough to rein in China’s power-sector emissions.

Who’s correct? On one hand, it’s fair to say that power planners usually err on the side of overestimation. If your forecast for electricity demand is too high, state-owned generators will be less profitable than they otherwise would have been — but if it’s too low, you’ll see power cuts and shutdowns like China witnessed last autumn, with resulting power woes affecting supply chains beyond its borders.

On the other hand, the decarbonization of China’s economy itself should drive electricity demand well above what we’ve seen in the past, with some projections such as electricity meeting 60% of energy use by 2060 pointing to a profound shift. Some 3.3 million electric vehicles were sold in 2021 and BloombergNEF estimates a further 5.7 million will be bought in 2022. Every million EVs will likely add in the region of 2 TWh of load to the grid. Those sums quickly mounts up in a country where electric drivetrains are taking over a market that shifts more than 25 million new cars a year.

Decarbonizing industry, a key element on China’s road to zero emissions, could also change the picture. The IEA sees the country building 25 GW of electolysers to produce hydrogen by 2030, enough to consume some 200 TWh on their own if run close to full-time.

That’s still not enough to justify the scale of demand being forecast, though. China is already one of the least efficient countries in the world when it comes to translating energy into economic growth, and despite official pressure on the most wasteful, so called “dual-high” industries such as steel, oil refining, glass and cement, its targets for more thrifty energy usage remain pedestrian.

The countries that have decarbonized fastest are those, such as Germany, the U.K and the U.S., where Americans are using less electricity, that have seen power demand plateau or even decline, giving new renewable power a chance to swap out fossil-fired generators without chasing an ever-increasing burden on the grid. China’s inability to do this as its population peaks and energy consumption hits developed-country levels isn’t a sign of strength.

Instead, it’s a sign of a country that’s chronically unable to make the transition away from polluting heavy industry and toward the common prosperity and ecological civilization that its president keeps promising. Until China reins in that credit-fueled development model, the risks to its economy and the global climate will only increase.

Ontario Global Adjustment and ICI balance hydro rates, renewable cost shift, and peak demand. Class A and Class B customers face demand response decisions amid pandemic occupancy uncertainty and volatile GA charges through 2022.

Key Points

A pricing model where GA costs and ICI peak allocation shape Class A/B bills, driven by renewables cost shifts.

✅ Renewable cost shift trims GA; larger Class A savings expected.

✅ Class A peak strategy returns; occupancy uncertainty persists.

✅ Class B faces volatile GA; limited levers beyond efficiency.

Ontario’s large commercial electricity customers can approach the looming annual decision about their billing structure for the 12 months beginning July 1 with the assurance of long-term relief on a portion of their costs, amid changes coming for electricity consumers that could affect planning. That’s to be weighed against uncertainties around energy demand and whether a locked-in cost allocation formula that looked favourable in pre-pandemic times will remain so until June 30, 2022.

“The biggest unknown is we just don’t know when the people are coming back,” Jon Douglas, director of sustainability with Menkes Property Management Services, reflected during a webinar sponsored by the Building Owners and Managers Association (BOMA) of Greater Toronto last week. “The occupancy in our office buildings this fall, and going into the new year, could really impact the outcome of the decision.”

After a year of operational upheaval and more modifications to provincial electricity pricing policies, BOMA Toronto’s regularly scheduled workshop ahead of the June 15 deadline for eligible customers to opt into the Industrial Conservation Initiative (ICI) program had a lot of ground to cover. Notably, beginning in January, all commercial customers have seen a reduction in the global adjustment (GA) component of their monthly hydro bills after the Ontario government shifted costs associated with contracted non-hydroelectric renewable supply to reduce the burden on industrial ratepayers from electricity rates to the general provincial account — a move that trims approximately $258 million per month from the total GA charged to industrial and commercial customers. However, they won’t garner the full benefit of that until 2022 since they’re currently repaying about $333 million in GA costs that were deferred in April, May and June of 2020.

Renewable cost shift pares the global adjustment
For now, Ontario government officials estimate the renewable cost shift equates to a 12 per cent discount relative to 2020 prices, even as typical bills may rise about 2% as fixed pricing ends in some cases. Once last year’s GA deferral is repaid at the end of 2021, they project the average Class A customer participating in the ICI program should realize a 16 per cent saving on the total hydro bill, while Class B customers paying the GA on a volumetric per kilowatt-hour (kWh) basis will see a slightly more moderate 15 per cent decrease.

“This is the biggest change to electricity pricing that’s happened since the introduction of ICI,” Tim Christie, director of electricity policy, economics and system planning for Ontario’s Ministry of Energy, Northern Development and Mines, told online workshop attendees. “The government is funding the out-of-market costs of renewables. It does tail off into the 2030s as those contracts (for wind, solar and biomass generation) expire, but over the next eight-ish years, it’s pretty steady at around just over $3 billion per year.”

Extrapolating from 2020 costs, he pegged average electricity costs at roughly 9.1 cents/kWh for Class A commercial customers and 13.2 cents/kWh for Class B, a point of concern for Ontario manufacturers facing high rates as well. However, energy management specialists suggest actual 2021 numbers haven’t proved that out.

“In commercial buildings, we’re averaging 10 to 12 cents for Class A in 2021, and we’re seeing more than that for about 14, 15 cents for Class B,” reported Scott Rouse, managing partner with the consulting firm, Energy@Work.

GA costs for Class B customers dropped nearly 30 per cent in the first four months of 2021 compared to the last four months of 2020, when they averaged 11.8 cents/kWh. Thus far, though, there have been significant month-to-month fluctuations, with a low of 5.04 cents/kWh in February and a high of 10.9 cents/kWh in April contributing to the four-month average of 8.3 cents/kWh.

“In 2020, system-wide GA very often averaged more than $1 billion per month,” Rouse said. “This February it dropped to $500 million, which was really quite surprising. So it is a very volatile cost.”

Although welcome, the renewable cost shift does alter the payback on energy-saving investments, particularly for demand response mechanisms like energy storage. When combined with pandemic-related uncertainty and a series of policy and program reversals alongside calls to clean up Ontario’s hydro policy in recent years, the industry’s appetite for some more capital-intensive technologies appears to be flagging.

“Volatility puts a pause on some of the innovation,” said Terry Flynn, general manager with BentallGreenOak and chair of BOMA Toronto’s energy committee. “It could be a leading edge, but it might be a bleeding edge that won’t bear any fruit because the way the commodity costs are structured will change.”

“There’s kind of a wait-and-see approach on some of these bigger investments,” Douglas concurred.

Industrial Conservation Initiative underpins commercial class divide
Turning to the ICI, Class A customers — defined as those with average monthly energy demand of at least 1 megawatt (MW) — encountered some unexpected changes to the program rules during 2020. Meanwhile, Class B customers — encompassing the vast share of commercial properties smaller than about 350,000 square feet — confront the persistent reality of electricity cost allocation that offloads the burden from larger players onto them.

Through the ICI, participating Class A customers pay a share of the global adjustment that’s prorated to their energy use during the five hours of the period from May 1 to April 30 when the highest overall system demand is recorded. This gives Class A customers the opportunity to lock in a favourable factor for calculating their share of monthly system-wide global adjustment costs if they can successful project and curtail energy loads during those five hours of peak demand. On the flipside, Class B customers pay the remainder of those system-wide costs, on a straightforward per-kWh basis, once Class A payments have been reconciled.

“Class B has sometimes been regarded as the forgotten middle child of the customer classes in Ontario where all the shifted costs in the system kind of pile up,” acknowledged Mark Olsheski, vice president, energy and environment, with Sussex Strategy Group. “Likewise, there can be big unpredictable and uncontrollable swings in the global adjustment rate from month to month and, outside of pure energy efficiency, there really is precious little opportunity or empowerment for a Class B customer to take actions to lower their bills.”

Nevertheless, COVID-19 presents a few extra hiccups for Class A customers this year. Conventionally, late May is when they receive notification of the cost allocation factor that would be used to determine their GA for the upcoming July 1 to June 30 period. This year, though, all current ICI participants will retain the factor they secured by responding to the five hours of peak demand during the 12 months from May 1, 2019 to April 30, 2020 after the Ontario government placed a temporary halt on the peak demand response aspect of the program last summer. Regardless, eligible ICI participants must formally opt into the program by June 15 or they will be billed as Class B customers.

Peak chasing resumes for summer 2021
Since peak demand hours conventionally occur from June to September, Class A customers will once again be studying forecasts intently and preparing to respond via Peak Perks as the heat wave season sets in. That should help alleviate some of the system stresses that arose last summer — prompting policy-makers to reject lobbying for a continued pause on peak demand response.

“The policy rationale was to allow consumers to focus on their operations when recovering from COVID as opposed to reducing peaks. The other issue was that we did not expect the peaks to be high last summer given COVID shutdowns,” Christie recounted. “But due to some hot weather, more people at home and also the lack of ICI response, we saw peaks we haven’t seen in many, many years come up last summer. So the peak hiatus has ended and this summer we’ll be back to responding to ICI as per normal.”

Among Class A customers, owners/managers of office and retail facilities generally have the most to lose from a billing formula tied to the energy demand of more densely occupied buildings in the summer of 2019. However, they could be much more competitively positioned for 2022-23 if their buildings remain below full occupancy and energy demand stays lower than usual this summer.

“Where we can improve is the IESO (Independent Electricity System Operator) and the LDCs (local distribution companies) need to help customers get their real-time data, especially in light of the phantom demand issue, interpret their bills and their Class A versus B scenarios much more easily and comprehensively,” urged Lee Hodgkinson, vice president, technical services, sustainability and ESG, with Dream Unlimited. “ I look for APIs (application programming interface) and direct data flow from the LDCs to the building owners so that we can access that data really easily.”

Given Class A’s historic advantages, few eligible ICI participants are expected to migrate out to Class B. From a sustainability perspective, there’s perhaps more cause to question how the ICI’s 1-MW threshold encourages strategies to move in the other direction.

“You could jack up demand in some buildings and get them into Class A basically by firing up the chillers on the weekend and then pouring cooling outside to get rid of it,” Douglas noted. “That has nothing to do with climate change strategy or sustainability, but it’s a cost- saving strategy, and, sometimes, when you look at the math, it’s hundreds of thousands of dollars you can save.”

Brian Hewson, vice president, consumer protection and industry performance with the Ontario Energy Board (OEB), confirmed the OEB is currently scrutinizing the discrepancy that leaves Class B as the only consumer group with no flexibility to curtail energy load during higher-priced periods, and will be providing advice to the Ministry of Energy. In the interim, that status does, at least, simplify tactics.

“Just reduce your kWh and it doesn’t matter what time of day because you’re paying that fixed rate for 24 hours a day. So if you can curb your demand at night, you get a big bang for your dollar,” Rouse advised.

“We do talk about rates a lot, but if you’re not using it, you’re not paying for it,” Flynn agreed. “A lot of our focus is still on really to try to reduce the number of kilowatts that we use. That seems to be the best thing to do.”

Electric weed-zapping farm robots enable precision agriculture, using autonomous mapping, per-plant targeting, and robotics to reduce pesticides, improve soil health, boost biodiversity, and lower costs with data-driven, selective weeding and seed-planting workflows.

Key Points

Autonomous machines that map fields, electrocute weeds per plant, and plant seeds, cutting pesticides, inputs, and costs.

✅ Precision agriculture: per-plant targeting reduces pesticide use up to 95%.

✅ Autonomous mapping robot surveys 20 hectares per day for weed data.

✅ Electric weeding and seeding improve soil health, biodiversity, and ROI.

On a field in England, three robots have been given a mission: to find and zap weeds with electricity, as advances in digitizing the electrical system continue to modernize power infrastructure, before planting seeds in the cleared soil.

The robots — named Tom, Dick and Harry — were developed by Small Robot Company to rid land of unwanted weeds with minimal use of chemicals and heavy machinery, complementing emerging options like electric tractors that aim to cut on-farm emissions.
The startup has been working on its autonomous weed killers since 2017, and this April launched Tom, its first commercial robot which is now operational on three UK farms. The other robots are still in the prototype stage, undergoing testing.

Small Robot says robot Tom can scan 20 hectares (49 acres) a day, collecting data, with AI-driven analysis guiding Dick, a "crop-care" robot, to zap weeds. Then it's robot Harry's turn to plant seeds in the weed-free soil.

Using the full system, once it is up and running, farmers could reduce costs by 40% and chemical usage by up to 95%, the company says, and integration with virtual power plants could further optimize energy use on electrified farms.

According to the UN Food and Agriculture Organization six million metric tons of pesticides were traded globally in 2018, valued at $38 billion.

"Our system allows farmers to wean their depleted, damaged soils off a diet of chemicals," says Ben Scott-Robinson, Small Robot's co-founder and CEO.

Zapping weeds
Small Robot says it has raised over £7 million ($9.9 million). Scott-Robinson says the company hopes to launch its full system of robots by 2023, which will be offered as a service at a rate of around £400 ($568) per hectare. The monitoring robot is placed at a farm first and the weeding and planting robots delivered only when the data shows they're needed — a setup that ultimately relies on a resilient grid, where research into preventing ransomware attacks is increasingly relevant.

To develop the zapping technology, Small Robot partnered with another UK-based startup, RootWave, while innovations like electricity from snow highlight the breadth of emerging energy tech.

"It creates a current that goes through the roots of the plant through the soil and then back up, which completely destroys the weed," says Scott-Robinson. "We can go to each individual plant that is threatening the crop plants and take it out."

"It's not as fast as it would be if you went out to spray the entire field," he says. "But you have to bear in mind we only have to go into the parts of the field where the weeds are." Plants that are neutral or beneficial to the crops are left untouched.

Small Robot calls this "per plant farming" — a type of precise agriculture where every plant is accounted for and monitored.

A business case
For Kit Franklin, an agricultural engineering lecturer from Harper Adams University, efficiency remains a hurdle, even as utilities use AI to adapt to electricity demands that could support wider on-farm electrification.

"There is no doubt in my mind that the electrical system works," he tells CNN Business. "But you can cover hundreds of hectares a day with a large-scale sprayer ... If we want to go into this really precise weed killing system, we have to realize that there is an output reduction that is very hard to overcome."

But Franklin believes farmers will adopt the technology if they can see a business case.

"There's a realization that farming in an environmentally friendly way is also a way of farming in an efficient way," he says. "Using less inputs, where and when we need them, is going to save us money and it's going to be good for the environment and the perception of farmers."

As well as reducing the use of chemicals, Small Robot wants to improve soil quality and biodiversity.

"If you treat a living environment like an industrial process, then you are ignoring the complexity of it," Scott-Robinson says. "We have to change farming now, otherwise there won't be anything to farm."

China Energy Crisis drives electricity shortages, power cuts, and blackouts as coal prices surge, carbon-neutrality rules tighten, and manufacturing hubs ration energy, disrupting supply chains and industrial output ahead of winter demand peaks.

Key Points

A power shortfall from costly coal, price caps, and emissions targets, causing blackouts and industrial rationing.

✅ Coal prices soar while electricity tariffs are capped

✅ Factories in northeast hubs face rationing and downtime

✅ Supply chains risk delays ahead of winter demand

China is struggling with a severe shortage of electricity which has left millions of homes and businesses hit by power cuts.

Blackouts are not that unusual in the country but this year a number of factors have contributed to a perfect storm for electricity suppliers, including surging electricity demand globally.

The problem is particularly serious in China's north eastern industrial hubs as winter approaches - and is something that could have implications for the rest of the world.

Why has China been hit by power shortages?
The country has in the past struggled to balance electricity supplies with demand, which has often left many of China's provinces at risk of power outages.

During times of peak power consumption in the summer and winter the problem becomes particularly acute.

But this year a number of factors have come together to make the issue especially serious.

As the world starts to reopen after the pandemic, demand for Chinese goods is surging and the factories making them need a lot more power, highlighting China's electricity appetite in recent months.

Rules imposed by Beijing as it attempts to make the country carbon neutral by 2060 have seen coal production slow, even as the country still relies on coal for more than half of its power and as low-emissions generation is set to cover most global demand growth.

And as electricity demand has risen, the price of coal has been pushed up.

But with the government strictly controlling electricity prices, coal-fired power plants are unwilling to operate at a loss, with many drastically reducing their output instead.

Who is being affected by the blackouts?
Homes and businesses have been affected by power cuts as electricity has been rationed in several provinces and regions.

The state-run Global Times newspaper said there had been outages in four provinces - Guangdong in the south and Heilongjiang, Jilin and Liaoning in the north east. There are also reports of power cuts in other parts of the country.

Companies in major manufacturing areas have been called on to reduce energy usage during periods of peak demand or limit the number of days that they operate.

Energy-intensive industries such as steel-making, aluminium smelting, cement manufacturing and fertiliser production are among the businesses hardest hit by the outages.

What has the impact been on China's economy?
Official figures have shown that in September 2021, Chinese factory activity shrunk to the lowest it had been since February 2020, when power demand dropped as coronavirus lockdowns crippled the economy.

Concerns over the power cuts have contributed to global investment banks cutting their forecasts for the country's economic growth.

Goldman Sachs has estimated that as much as 44% of the country's industrial activity has been affected by power shortages. It now expects the world's second largest economy to expand by 7.8% this year, down from its previous prediction of 8.2%.

Globally, the outages could affect supply chains, including solar supply chains as the end-of-the-year shopping season approaches.

Since economies have reopened, retailers around the world have already been facing widespread disruption amid a surge in demand for imports.

China's economic planner, the National Development and Reform Commission (NDRC), has outlined a number of measures to resolve the problem, with energy supplies in the northeast of the country as its main priority this winter.

The measures include working closely with generating firms to increase output, ensuring full supplies of coal and promoting the rationing of electricity.

The China Electricity Council, which represents generating firms, has also said that coal-fired power companies were now "expanding their procurement channels at any cost" in order to guarantee winter heat and electricity supplies.

However, finding new sources of coal imports may not be straightforward.

Russia is already focused on its customers in Europe, Indonesian output has been hit by heavy rains and nearby Mongolia is facing a shortage of road haulage capacity,

Are energy shortages around the world connected?
Power cuts in China, UK petrol stations running out of fuel, energy bills jumping in Europe, near-blackouts in Japan and soaring crude oil, natural gas and coal prices on wholesale markets - it would be tempting to assume the world is suddenly in the grip of a global energy drought.

However, it is not quite as simple as that - there are some distinctly different issues around the world.

For example, in the UK petrol stations have run dry as motorists rushed to fill up their vehicles over concerns that a shortage of tanker drivers would mean fuel would soon become scarce.

Meanwhile, mainland Europe's rising energy bills and record electricity prices are due to a number of local factors, including low stockpiles of natural gas, weak output from the region's windmills and solar farms and maintenance work that has put generating operations out of action.
