Power crisis halts South African mines for a second day

Electric Vehicle Grid Integration aligns EV charging with grid capacity using smart charging, time-of-use rates, V2G, and demand response to reduce peak load, enable renewable energy, and optimize infrastructure planning.

Key Points

Aligning EV charging with grid needs via smart charging, TOU pricing, and V2G to balance load and support renewables.

✅ Time-of-use rates shift charging to off-peak hours

✅ Smart charging responds to real-time grid signals

✅ V2G turns fleets into distributed energy storage

When Seattle City Light unveiled five new electric vehicle charging stations last month in an industrial neighborhood south of downtown, the electric utility wasn't just offering a new spot for drivers to fuel up. It also was creating a way for the service to figure out how much more power it might need as electric vehicles catch on.

Seattle aims to have nearly a third of its residents driving electric vehicles by 2030. Washington state is No. 3 in the nation in per capita adoption of plug-in cars, behind California and Hawaii. But as Washington and other states urge their residents to buy electric vehicles — a crucial component of efforts to reduce carbon emissions — they also need to make sure the electric grid can handle it amid an accelerating EV boom nationwide.

The average electric vehicle requires 30 kilowatt hours to travel 100 miles — the same amount of electricity an average American home uses each day to run appliances, computers, lights and heating and air conditioning.

An Energy Department study found that increased electrification across all sectors of the economy could boost national consumption by as much as 38 percent by 2050, in large part because of electric vehicles. The environmental benefit of electric cars depends on the electricity being generated by renewables.

So far, states predict they will be able to sufficiently boost power production. But whether electric vehicles will become an asset or a liability to the grid largely depends on when drivers charge their cars.

Electricity demand fluctuates throughout the day; demand is higher during daytime hours, peaking in the early evening. If many people buy electric vehicles and mostly try to charge right when they get home from work — as many now do — the system could get overloaded or force utilities to deliver more electricity than they are capable of producing.

In California, for example, the worry is not so much with the state’s overall power capacity, but rather with the ability to quickly ramp up production and maintain grid stability when demand is high, said Sandy Louey, media relations manager for the California Energy Commission, in an email. About 150,000 electric vehicles were sold in California in 2018 — 8 percent of all state car sales.

The state projects that electric vehicles will consume 5.4 percent of the state’s electricity, or 17,000 gigawatt hours, by 2030.

Responding to the growth in electric vehicles will present unique challenges for each state. A team of researchers from the University of Texas at Austin estimated the amount of electricity that would be required if every car on the road transitioned to electric. Wyoming, for instance, would need to nudge up its electricity production only 17 percent, while Maine would have to produce 55 percent more.

Efficiency Maine, a state trust that oversees energy efficiency and greenhouse gas reduction programs, offers rebates for the purchase of electric vehicles, part of state efforts to incentivize growth.

“We’re certainly mindful that if those projections are right, then there will need to be more supply,” said Michael Stoddard, the program’s executive director. “But it’s going to unfold over a period of the next 20 years. If we put our minds to it and plan for it, then we should be able to do it.”

A November report sponsored by the Energy Department found that there has been almost no increase in electricity demand nationwide over the past 10 years, while capacity has grown an average of 12 gigawatts per year (1 GW can power more than a half-million homes). That means energy production could climb at a similar rate and still meet even the most aggressive increase in electric vehicles, with proper planning.

Charging during off-peak hours would allow not only many electric vehicles to be added to the roads but also utilities to get more use out of power plants that run only during the limited peak times through improved grid coordination and flexible demand.

Seattle City Light and others are looking at various ways to promote charging during ideal times. One method is time-of-day rates. For the Seattle chargers unveiled last month, users will pay 31 cents per kilowatt hour during peak daytime hours and 17 cents during off-peak hours. The utility will monitor use at its charging stations to see how effective the rates are at shifting charging to more favorable times.

The utility also is working on a pilot program to study charging behavior at home. And it is partnering with customers such as King County Metro that are electrifying large vehicle fleets, including growing electric truck fleets that will demand significant power, to make sure they have both the infrastructure and charging patterns to integrate smoothly.

“Traditionally, our utility approach is to meet the load demand,” said Emeka Anyanwu, energy innovation and resources officer for Seattle City Light.

Instead, he said, the utility is working with customers to see whether they can use existing assets without the need for additional investment.

Numerous analysts say that approach is crucial.

“Even if there’s an overall increase in consumption, it really matters when that occurs,” said Sally Talberg, head of the Michigan Public Service Commission, which oversees the state’s utilities. “The encouragement of off-peak charging and other technology solutions that could come to bear could offset any negative impact.”

One of those solutions is smart charging, a system in which vehicles are plugged in but don’t charge until they receive a signal from the grid that demand has tapered off a sufficient amount. This is often paired with a lower rate for drivers who use it. Several smart-charging pilot programs are being conducted by utilities, although they have not yet been phased in widely, amid ongoing debates over charging control among manufacturers and utilities.

In many places, the increased electricity demand from electric vehicles is seen as a benefit to utilities and rate payers. In the Northwest, electricity consumption has remained relatively stagnant since 2000, despite robust population growth and development. That’s because increasing urbanization and building efficiency have driven down electricity needs.

Electric vehicles could help push electricity consumption closer to utilities’ capacity for production. That would bring in revenue for the providers, which would help defray the costs for maintaining that capacity, lowering rates for all customers.

“Having EV loads is welcome, because it’s environmentally cleaner and helps sustain revenues for utilities,” said Massoud Jourabchi, manager of economic analysis for the Northwest Power and Conservation Council, which develops power plans for the region.

Colorado also is working to promote electric cars, with the aim of putting 940,000 on the road by 2030. The state has adopted California’s zero-emission vehicles mandate, which requires automakers to reach certain market goals for their sales of cars that don’t burn fossil fuels, while extending tax credits for the purchase of such cars, investing in charging stations and electrifying state fleets.

Auto dealers have opposed the mandate, saying it infringes on consumer freedom.

“We think it should be a customer choice, a consumer choice and not a government mandate,” said Tim Jackson, president and chief executive of the Colorado Automobile Dealers Association.

Jackson also said that there’s not yet a strong consumer appetite for electric vehicles, meaning that manufacturers that fail to sell the mandated number of emission-free vehicles would be required to purchase credits, which he thinks would drive up the price of their other models.

Republicans in the state have registered similar concerns, saying electric vehicle adoption should take place based on market forces, not state intervention.

Many in the utility community are excited about the potential for electric cars to serve as mobile energy storage for the grid. Vehicle-to-grid technology, known as V2G, would allow cars charging during the day to take on surplus power from renewable energy sources.

Then, during peak demand times, electric vehicles would return some of that stored energy to the grid. As demand tapers off in the evening, the cars would be able to recharge.

In practice, V2G technology could be especially beneficial if used by heavy-duty fleets, such as school buses or utility vehicles. Those fleets would have substantial battery storage and long periods where they are idle, such as evenings and weekends — and even longer periods such as summer and the holiday season when school is out. The batteries on a bus, Jourabchi said, could store as much as 10 times the electricity needed to power a home for a day.

Hospital Electricity Reliability underpins ICU operations, ventilators, medical devices, and diagnostics, reducing power outages risks via grid power and backup generators, while energy poverty and blackouts magnify COVID-19 mortality in vulnerable regions.

Key Points

Hospital electricity reliability is steady power that keeps ICU care, ventilators and medical devices operating.

✅ ICU loads: ventilators, monitors, infusion pumps, diagnostics

✅ Grid power plus backup generators minimize outage risk

✅ Energy poverty increases COVID-19 mortality and infection

Robert Bryce, Contributor

During her three-year career as a registered nurse, my friend, C., has cared for tuberculosis patients as well as ones with severe respiratory problems. She’s now caring for COVID-19 patients at a hospital in Ventura County, California, where debates about keeping the lights on continue amid the state’s energy transition. Is she scared about catching the virus? “No,” she replied during a phone call on Thursday. “I’m pretty unflappable.”

What would scare her? She quickly replied, “a power outage,” a threat that grows during summer blackouts when heat waves drive demand. About a year ago, while working in Oregon, the hospital she was working in lost power for about 45 minutes. “It was terrifying,” she said. 

C., who wasn’t authorized by her hospital to talk to the media, and thus asked me to only use the initial of her first name, said that COVID-19 patients are particularly reliant on electrical devices. She quickly ticked off the machines: “The bed, the IV machine, vital signs monitor, heart monitor, the sequential compression devices...” COVID-19 patients are hooked up to a minimum of five electrical devices, she said, and if the virus-stricken patient needs high-pressure oxygen or a ventilator, the number of electrical devices could be two or three times that number. “You name it, it plugs in,” she said.  

Today In: Energy

The virus has infected some 2.2 million people around the world and killed more than 150,000,including more than 32,000 people here in the U.S. While those numbers are frightening, it is apparent that the toll would be far higher without adequate supplies of reliable electricity. Modern healthcare systems depend on electricity. Hospitals are particularly big consumers. Power demand in hospitals is about 36 watts per square meter, which is about six times higher than the electricity load in a typical American home, and utilities are turning to AI to adapt to electricity demands during surges. 

Beating the coronavirus is all about electricity. Indeed, nearly every aspect of coronavirus detection, testing, and treatment requires juice. Second, it appears that the virus is more deadly in places where electricity is scarce or unreliable. Finally, if there are power outages in virus hotspots or hospitals, a real risk in a grid with more blackouts than other developed countries, the damage will be even more severe. 

As my nurse friend in Ventura County made clear, her ability to provide high-quality care for patients is wholly dependent on reliable electricity. The thermometers used to check for fever are powered by electricity. The monitors she uses to keep track of her patients, as well as her Vocera, the walkie-talkie that she uses to communicate with her colleagues, runs on batteries. Testing for the virus requires electricity. One virus-testing machine, Abbott Labs’ m2000, is a 655-pound appliance that, according to its specification sheet, runs on either 120 or 240 volts of electricity. The operating manual for a ventilator made by Hamilton Medical is chock full of instructions relating to electricity, including how to manage the machine’s batteries and alarms. 

While it may be too soon to make a direct connection between lack of electricity and the lethality of the coronavirus, the early signs from the Navajo reservation indicate that energy poverty amplifies the danger. The sprawling reservation has about 175,000 residents, but it has a higher death toll from the virus than 13 states. About 10 percent of Navajos do not have electricity in their homes and more than 30 percent lack indoor plumbing. 

The death rate from the virus on the reservation now stands at 3.4 percent, which is nearly twice the global average. In the middle of last week, the entire population of Native American tribes in the U.S. accounted for about 1,100 confirmed cases of the virus and about 44 deaths. Navajos accounted for the majority of those, with 830 confirmed cases of coronavirus and 28 deaths. 

On Saturday night, the Navajo Times reported a major increase, with 1,197 positive cases of COVID-19 on the reservation and 44 deaths. Other factors may contribute to the high infection and mortality rates on the reservation, including  high rates of diabetes, obesity, and crowded residential living situations. That said, electricity and water are essential to good hygiene and health authorities say that frequent hand washing helps cut the risk of contracting the virus. 

The devastation happening on Navajoland provides a window into what may happen in crowded, electricity-poor countries like India, Pakistan, and Bangladesh. It also shows what could happen if a tornado or hurricane were to wipe out the electric grid in virus hotspots like New Orleans, as extreme weather increasingly afflicts the grid nationwide. Sure, most American hospitals have backup generators to help assure reliable power. But those generators can fail. Further, they usually burn diesel fuel which needs to be replenished every few days. 

The essential point here is that our hospitals and critical health care machines aren’t running on solar panels and batteries. Instead, they are running on grid power that’s being provided by reliable sources — coal, natural gas, hydro, and nuclear power — which together produce about 89 percent of the electricity consumed in this country, even as Russian hacking of utilities highlights cyber risks. The pandemic — which is inflicting trillions of dollars of damage on our economy and tens of thousands of deaths — underscores the criticality of abundant and reliable electricity to our society and the tremendous damage that would occur if our health care infrastructure were to be hit by extended blackouts during the fight to stop COVID-19.

In a follow-up interview on Saturday with my friend, C., she told me that while caring for patients, she and her colleagues “are entirely dependent on electricity. We take it for granted. It’s a hidden assumption in our work,” a reminder echoed by a grid report card that warns of dangerous vulnerabilities. She quickly added she and her fellow nurses “aren’t trained or equipped to deal with circumstances that would come with shoddy power. If we lost power completely, people will die.”

Yukon-BC Electricity Intertie could link Yukon to BC's hydroelectric power, enabling renewable energy integration, net-zero grid goals by 2035, transmission expansion for mining, and stronger Arctic energy security through a coast-to-coast network.

Key Points

A link connecting Yukon's grid to BC hydro to import renewables, cut emissions, and strengthen northern energy security.

✅ Enables renewable imports to meet 2035 net-zero electricity target

✅ Supports mining growth with reliable, low-carbon power

✅ Enhances Arctic energy security via national grid integration

Yukon's energy minister says Canada's push for more green energy and a net-zero electricity grid should spark renewed interest in connecting the territory's power to British Columbia, home to the Electric Highway network.

Minister of Energy, Mines and Resources John Streicker says linking the territory's power grid to the south would help with the national move to renewable energy, including new wind turbines being added in the Yukon, support the mineral extraction required for green projects, and improve northern energy and Arctic security.

"We're getting to the moment in time when we will want an electricity grid which stretches from coast to coast to coast. … I think that the moment is coming for this — it's sort of a nation-building moment. And I think that from the Yukon's perspective, we're very interested," Streicker said in an interview.

The idea of a link, originally proposed to span 763 kilometres between Whitehorse and Iskut, B.C., was first floated in 2016 but sat on the shelf after a viability study put the price tag at as much as $1.7 billion, even as a study indicates B.C. may need to double its power output to electrify all road vehicles.

Two years later, Yukon's then-energy-minister Ranj Pillai — now premier — mused again about the possibility of connecting to power from B.C., where green energy ambitions include the Site C hydro dam.

The idea appeared to have been resurrected at this year's Western Premiers' Conference in June, with both Pillai and B.C. Premier David Eby publicly mentioning early conversations about grid development and interties.

At the conference, Eby said British Columbia was fortunate to have the ability to support other jurisdictions with its hydro electricity.

"So certainly part of the conversation was how do we support each other in sharing our strength, including emerging hydrogen projects across the province?" he said.

"And one of those that British Columbia was able to put on the table is if we can find ways to enter ties with, for example, with the Yukon, to support them in their efforts to access more electricity to grow their economy and decarbonize their electrical grid, then that's very good news for everybody."

The federal government has set a target of making the country's electricity grid net-zero by 2035, while jurisdictions like the N.W.T. plan for more residents to drive electric vehicles as part of the transition.

New England Clean Energy Connect advances despite court delays, installing steel poles on a Maine corridor for Canadian hydropower, while legal challenges seek environmental review; permits, jobs, and grid upgrades drive the renewable transmission project.

Key Points

An HV line in Maine delivering 1,200 MW of Canadian hydropower to New England to cut emissions and stabilize costs.

✅ Appeals court pauses 53-mile new section; upgrades continue

✅ 1,200 MW hydropower aims to cut emissions, stabilize rates

✅ Permits issued; environmental review litigation ongoing

Construction on part of a $1 billion electricity transmission corridor through sparsely populated woods in western Maine is on hold because of legal action, echoing Clean Line's Iowa withdrawal amid court uncertainty, but that doesn't mean all building has been halted.

Workers installed the first of 829 steel poles Tuesday on a widened portion of the existing corridor that is part of the project near The Forks, as the groundwork is laid for the 145-mile ( 230-kilometre ) New England Clean Energy Connect, a project central to Maine's debate over the 145-mile line moving forward.

The work is getting started even though the 1st U.S. Circuit Court of Appeals delayed construction of a new 53-mile ( 85-kilometre ) section.

Three conservation groups are seeking an injunction to delay the project while they sue to force the U.S. Army Corps of Engineers to conduct a more rigorous environmental review.

In western Maine, workers already have staged heavy equipment and timber “mats” that will be used to prevent the equipment from damaging the ground. About 275 Maine workers already have been hired, and more would be hired if not for the litigation, officials said.

“This project has always promised to provide an economic boost to Maine’s economy, and we are already seeing those benefits take shape," Thorn Dickinson, CEO of the New England Clean Energy Connect, said Tuesday.

The electricity transmission line would provide a conduit for up to 1,200 megawatts of Canadian hydropower, reducing greenhouse emissions and stabilizing energy costs in New England as states pursue Connecticut's market overhaul to improve market design, supporters say.

The project, which would be fully funded by Massachusetts ratepayers to meet the state's clean energy goals after New Hampshire rejected a Quebec-Massachusetts proposal elsewhere, calls for construction of a high-voltage power line from Mount Beattie Township on the Canadian border to the regional power grid in Lewiston, Maine.

Critics have been trying to stop the project, reflecting clashes over New Hampshire hydropower in the region, saying it would destroy wilderness in western Maine. They also say that the environmental benefits of the project have been overstated.

In addition to the lawsuit, opponents have submitted petitions seeking to have a statewide vote, even as a Maine court ruling on Hydro-Quebec exports has reshaped the legal landscape.

Sandi Howard, a leading opponent of the project, said the decision by the company to proceed showed “disdain for everyday Mainers” by ignoring permit appeals and ongoing litigation.

“For years, CMP has pushed the false narrative that their unpopular and destructive project is a ‘done deal’ to bully Mainers into submission on this for-profit project. But to be clear, we won’t stop until Maine voters (their customers), have the chance to vote,” said Howard, who led the referendum petition drive for the No CMP Corridor PAC.

The project has received permits from the Army Corps, Maine Department of Environmental Protection, Maine Land Use Planning Commission and Maine Public Utilities Commission.

The final approval came in the form of a presidential permit issued last month from the U.S. Department of Energy, providing green light for the interconnect at the Canadian border, even as customer backlash to utility acquisitions elsewhere underscores public scrutiny.

BEST vigilance raid on Wadala electricity theft uncovered a Mumbai power theft racket in Antop Hill and Sangam Nagar, with operators, illegal connections, sub-stations, meter cabins, FIRs, and Rs 72 lakh losses flagged by BEST.

Key Points

A BEST operation that nabbed operators stealing power via illegal connections in Wadala, exposing a Rs 72 lakh loss.

✅ 35 suspects booked; key operator identified as David Anthony.

✅ Illegal taps from sub-stations and meter cabins in shanties.

✅ BEST filed FIRs; Session court granted bail to accused.

In a raid conducted at Antop Hill in Wadala on Saturday, a total of 35 people were nabbed by the vigilance department for stealing electricity to the tune of Rs 72 lakh, in a case similar to a Montreal power-theft ring bust covered internationally.

It was the second such raid conducted in the past one week, where operators have been nabbed.The cash-strapped BEST is now tightening it's grasp on `operators' who steal electricity from BEST sources and provide it to their own customers on a meagre monthly rent, even as Ontario utilities warn about scams affecting customers elsewhere.

After receiving a tip-off about the theft of electricity in the Sangam Nagar area of Wadala, about 90 personnel of the BEST conducted a raid. After visiting the spots, it was found that illegal connections were made from the sub-station and other electricity boxes of the BEST in the area, underscoring how fragile networks can be amid disruptions such as major outages in London that affected thousands.

According to BEST officials, the residents from the area would come up to the accused, identified as David Anthony, and would pay a fixed amount at the end of every month for unlimited supply of power, a dynamic reminiscent of shutoff-threat scams flagged by Manitoba Hydro, though the circumstances differ. Anthony would with draw power directly from meter cabins and electricity boxes in the area. The wires he connected to these were in turn connected to households who made the arrangement with him. An official from BEST also explained that as soon they reach a location to conduct raids and vehicles of BEST officials are spotted by residents, most of the connections are cut off, which makes it difficult for them to prove the theft case However, on Saturday, BEST officials managed to conduct the raid swiftly and nab 35 people.

All who had illegal connections were named in the complaint and an FIR was registered against them, including Anthony, who himself had illegal connections in his house. They were produced in Session court and given bail, while utilities in other regions resort to hydro disconnections during arrears season. Chief Vigilance Officer of BEST, RJ Singh said, "Most of these are commercial establishments in these shanties, which steal electricity. It is very important to catch hold of the operators as they are the providers and we need to break their backbone."

Cal ISO Flex Alert urges Southern California energy conservation as a Stage 2 emergency strains the power grid, with potential rolling blackouts during peak hours from 3 to 10 p.m., if demand exceeds supply.

Key Points

A statewide call to conserve power during high demand, issued by the grid operator to prevent rolling blackouts.

✅ Stage 2 emergency signals severe grid strain

✅ Peak Flex Alert hours: 3 to 10 p.m. statewide

✅ Set thermostats to 78 and avoid major appliances

Residents and businesses across Southern California were urged to conserve power Tuesday afternoon amid ongoing electricity inequities across the state as the manager of the state’s power grid warned rolling blackouts could be imminent for some power customers.

The California Independent System Operator (Cal ISO), which manages the state power grid, declared a Stage 2 emergency as of 2:30 p.m., indicating severe strain on the electrical system, similar to a recent grid alert in Alberta that relied on reserves.

ADVERTISING

Rolling blackouts for some customers could occur in a Stage 3 emergency, distinct from the intentional shut-offs some utilities use to reduce wildfire risk.

Cal ISO issued a statewide Flex Alert in effect from 3 to 10 p.m. Tuesday and Wednesday, with conservation considered especially critical during those hours, a concern heightened by pandemic-era grid operations this year.

Officials told reporters rolling blackouts might be avoided Tuesday evening if residents repeat the level of conservation seen Monday.
“If we can get the same sort of response we got yesterday, we can minimize this, or perhaps avoid it altogether,” Cal-ISO President/CEO Steve Berberich said, noting that some operators have even planned staff lockdowns during COVID-19 to maintain reliability.

Cal-ISO controls roughly 80% of the state’s power grid through Southern California Edison, Pacific Gas and Electric Co., with the utility recently restoring power after shut-offs in affected communities, and San Diego Gas & Electric.

Residents are urged to set thermostats at 78 in the afternoon and evening hours and avoiding the use of air conditioning and major appliances during the Flex Alert hours, as utilities like PG&E prepare for winter storms to improve resilience.
