600,000 without power after epic ice storm

U.S. Power Grid Supply Shortages strain reliability as heat waves, hurricanes, and drought drive peak demand; transformer scarcity, gas constraints, and renewable delays raise outage risks across ERCOT and MISO, prompting FERC warnings.

Key Points

They are equipment and fuel constraints that, amid extreme weather and peak demand, elevate outage risks.

✅ Transformer shortages delay storm recovery and repairs.

✅ Record gas burn, low hydro tighten generation capacity.

✅ ERCOT and MISO warn of rolling outages in heat waves.

U.S. power companies are facing supply crunches amid the U.S. energy crisis that may hamper their ability to keep the lights on as the nation heads into the heat of summer and the peak hurricane season.

Extreme weather events such as storms, wildfires and drought are becoming more common in the United States. Consumer power use is expected to hit all-time highs this summer, reflecting unprecedented electricity demand across the Eastern U.S., which could strain electric grids at a time when federal agencies are warning the weather could pose reliability issues.

Utilities are warning of supply constraints for equipment, which could hamper efforts to restore power during outages. They are also having a tougher time rebuilding natural gas stockpiles for next winter, after the Texas power system failure highlighted cold-weather vulnerabilities, as power generators burn record amounts of gas following the shutdown of dozens of coal plants in recent years and extreme drought cuts hydropower supplies in many Western states.

"Increasingly frequent cold snaps, heat waves, drought and major storms continue to challenge the ability of our nation’s electric infrastructure to deliver reliable affordable energy to consumers," Richard Glick, chairman of the U.S. Federal Energy Regulatory Commission (FERC), said earlier this month.

Federal agencies responsible for power reliability like FERC have warned that grids in the western half of the country could face reliability issues this summer as consumers crank up air conditioners to escape the heat, with nationwide blackout risks not limited to Texas. read more

Some utilities have already experienced problems due to the heat. Texas' grid operator, the Electric Reliability Council of Texas (ERCOT), was forced to urge customers to conserve energy as the Texas power grid faced another crisis after several plants shut unexpectedly during an early heat wave in mid-May. read more

In mid-June, Ohio-based American Electric Power Co (AEP.O) imposed rolling outages during a heat wave after a storm damaged transmission lines and knocked out power to over 200,000 homes and businesses.

The U.S. Midwest faces the most severe risk because demand is rising while nuclear and coal power supplies have declined. read more

The Midcontinent Independent System Operator (MISO), which operates the grid from Minnesota to Louisiana, warned that parts of its coverage area are at increased risk of temporary outages to preserve the integrity of the grid.

Supply-chain issues have already delayed the construction of renewable energy projects across the country, and the aging U.S. grid is threatening progress on renewables and EVs. Those renewable delays coupled with tight power in the Midwest prompted Wisconsin's WEC Energy Group Inc (WEC.N) and Indiana's NiSource Inc (NI.N) to delay planned coal plant shutdowns in recent months.

BRACING FOR SUPPLY SHORTAGES
Utility operators are conserving their inventory of parts and equipment as they plan to prevent summer power outages during severe storms. Over the last several months, that means operators have been getting creative.

"We’re doing a lot more splicing, putting cables together, instead of laying new cable because we're trying to maintain our new cable for inventory when we need it," Nick Akins, chief executive of AEP, said at the CERAWeek energy conference in March.

Transformers, which often sit on top of electrical poles and convert high-voltage energy to the power used in homes, are in short supply.

New Jersey-based Public Service Enterprise Group Inc (PSEG) (PEG.N) Chief Executive Ralph Izzo told Reuters the company has had to look at alternate supply options for low voltage transformers.

"You don’t want to deplete your inventory because you don't know when that storm is coming, but you know it's coming," Izzo said.

Some utilities are facing waiting times of more than a year for transformer parts, the National Rural Electric Cooperative Association and the American Public Power Association told U.S. Energy Secretary Jennifer Granholm in a May letter.

Summer is just starting, but U.S. weather so far this year has already been about 21% warmer than the 30-year norm, according to data provider Refinitiv.

"If we have successive days of 100-degree-heat, those pole top transformers, they start popping like Rice Krispies, and we would not have the supply stack to replace them," Izzo said.

US Electricity Demand Outlook examines EIA forecasts, GDP decoupling, energy efficiency, electrification, electric vehicles, grid load growth, and weather variability to frame long term demand trends and utility planning scenarios.

Key Points

An analysis of EIA projections showing demand decoupling from GDP, with EV adoption and efficiency shaping future grid load.

✅ EIA lowers load growth; demand decouples from GDP.

✅ Efficiency and sector shifts depress kWh sales.

✅ EV adoption could revive load and capacity needs.

Electricity producers and distributors are in an unusual business. The product they provide is available to all customers instantaneously, literally at the flip of a switch. But the large amount of equipment, both hardware and software to do this takes years to design, site and install.

From a long range planning perspective, just as important as a good engineering design is an accurate sales projections. For the US electric utility industry the most authoritative electricity demand projec-tions come from the Department of Energy’s Energy Information Administration (EIA). EIA's compre-hensive reports combine econometric analysis with judgment calls on social and economic trends like the adoption rate of new technologies that could affect future electricity demand, things like LED light-ing and battery powered cars, and the rise of renewables overtaking coal in generation.

Before the Great Recession almost a decade ago, the EIA projected annual growth in US electricity production at roughly 1.5 percent per year. After the Great Recession began, the EIA lowered its projections of US electricity consumption growth to below 1 percent. Actual growth has been closer to zero. While the EIA did not antici-pate the last recession or its aftermath, we cannot fault them on that.

After the event, though, the EIA also trimmed its estimates of economic growth. For the 2015-2030 period it now predicts 2.1 percent economic and 0.3 percent electricity growth, down from previously projections of 2.7 percent and 1.3 percent respectively. (See Figures 1 and 2.)

Table 1. EIA electric generation projections by year of forecast (kWh billions)

Table 2. EIA forecast of GDP by year of forecast (billion 2009 $)

Back in 2007, the EIA figured that every one percent increase in economic activity required a 0.48 percent in-crease in electric generation to support it. By 2017, the EIA calculated that a 1 percent growth in economic activity now only required a 0.14 percent increase in electric output. What accounts for such a downgrade or disconnect between electricity usage and economic growth? And what factors might turn the numbers 
around?

First, the US economy lost energy intensive heavy industry like smelting, steel mills and refineries; patterns in China's electricity sector highlight how industrial shifts can reshape power demand. A more service oriented economy (think health care) relies more heavily on the movement of data or information and uses far less power than a manufacturing-oriented economy.

A small volcano in Argentina is about to fuel the next tech boom – and a little known company is going to be right at the center. Early investors stand to gain incredible profits and you can too. Read the report.

Second, internet shopping has hurt so-called "brick and mortar" retailers. Despite the departure of heavy industry, in years past a burgeoning US commercial sector increased its demand and usage of electricity to offset the industrial decline. But not anymore. Energy efficiency measures as well as per-haps greater concern about global warming and greenhouse gas emissions and have cut into electricity sales. “Do more with less” has the right ring to it.

But there may be other components to the ongoing decline in electricity usage. Academic studies show that electricity usage seems to increase with income along an S curve, and flattens out after a certain income level. That is, if you earn $1 billion per year you do not (or cannot) use ten times a much electricity as someone earning only $100 million.

But people at typical, middle income levels increase or decrease electricity usage when incomes rise or fall. The squeeze on middle income families was discussed often in the late presidential campaign. In recent decades an increasing percentage of income has gone to a small percentage of the population at the top of the income scale. This trend probably accounts for some weakness in residential sales. This suggests that government policy addressing income inequality would also boost electricity sales.

Population growth affects demand for electricity as well as the economy as a whole. The EIA has made few changes in its projections, showing 0.7 percent per year population growth in 2015- 2030 in both the 2007 and 2017 forecasts. Recent studies, however, have shown a drop in the birth rate to record lows. More troubling, from a national health perspective is that the average age of death may have stopped rising. Those two factors point to lower population growth, especially if the government also restricts immi-gration. Thus, the US may be approaching a period of rather modest population growth.

All of the above factors point to minimal sales growth for electricity producers in the US--perhaps even lower than the seemingly conservative EIA estimates. But the cloud on the horizon has a silver lining in the shape of an electric car. Both the United Kingdom and France have set dates to end of production of automobiles with internal combustion engines. Several European car makers have declared that 20 percent of their output will be electric vehicles by the early 2020s. If we adopt automobiles powered by electricity and not gasoline or diesel, electricity sales would increase by one third. For the power indus-try, electric vehicles represent the next big thing.

We don’t pretend to know how electric car sales will progress. But assume vehicle turnover rates re-main at the current 7 percent per year and electric cars account for 5 percent of sales in the first five years (as op-posed to 1 percent now), 20 percent in the next five years and 50 percent in the third five year period. Wildly optimistic assumptions? Maybe. By 2030, electric cars would constitute 28 percent of the vehicle fleet. They would add about 10 percent to kilowatt hour sales by that date, assuming that battery efficiencies do not improved by then. Those added sales would require increased electric generation output, with low-emissions sources expected to cover almost all the growth globally. They would also raise long term growth rates for 2015-2030 from the present 0.3 percent to 1.0 percent. The slow upturn in demand should give the electric companies time to gear up so to speak.

In the meantime, weather will continue to play a big role in electricity consumption. Record heat-induced demand peaks are being set here in the US even as surging global demand puts power systems under strain worldwide.

Can we discern a pattern in weather conditions 15 years out? Maybe we can, but that is one topic we don’t expect a government agency to tackle in public right now. Meantime, weather will affect sales more than anything else and we cannot predict the weather. Or can we?

EV Grid Capacity Management shows how smart charging, load balancing, and off-peak pricing align with utility demand response, DC fast charging networks, and renewable integration to keep national electricity infrastructure reliable as EV adoption scales

Key Points

EV Grid Capacity Management schedules charging and balances load to keep EV demand within utility capacity.

✅ Off-peak pricing and time-of-use tariffs shift charging demand.

✅ Smart chargers enable demand response and local load balancing.

✅ Gradual EV adoption allows utilities to plan upgrades efficiently.

One of the most frequent concerns you will see from electric vehicle haters is that the electricity grid can’t possibly cope with all cars becoming EVs, or that EVs will crash the grid entirely. However, they haven’t done the math properly. The grids in most developed nations will be just fine, so long as the demand is properly management. Here’s how.

The biggest mistake the social media keyboard warriors make is the very strange assumption that all cars could be charging at once. In the UK, there are currently 32,697,408 cars according to the UK Department of Transport. The UK national grid had a capacity of 75.8GW in 2020. If all the cars in the UK were EVs and charging at the same time at 7kW (the typical home charger rate), they would need 229GW – three times the UK grid capacity. If they were all charging at 50kW (a common public DC charger rate), they would need 1.6TW – 21.5 times the UK grid capacity. That sounds unworkable, and this is usually the kind of thinking behind those who claim the UK grid can't cope with EVs.

What they don’t seem to realize is that the chances of every single car charging all at once are infinitesimally low. Their arguments seem to assume that nobody ever drives their car, and just charges it all the time. If you look at averages, the absurdity of this position becomes particularly clear. The distance each UK car travels per year has been slowly dropping, and was 7,400 miles on average in 2019, again according to the UK Department of Transport. An EV will do somewhere between 2.5 and 4.5 miles per kWh on average, so let’s go in the middle and say 3.5 miles. In other words, each car will consume an average of 2,114kWh per year. Multiply that by the number of cars, and you get 69.1TWh. But the UK national grid produced 323TWh of power in 2019, so that is only 21.4% of the energy it produced for the year. Before you argue that’s still a problem, the UK grid produced 402TWh in 2005, which is more than the 2019 figure plus charging all the EVs in the UK put together. The capacity is there, and energy storage can help manage EV-driven peaks as well.

Let’s do the same calculation for the USA, where an EV boom is about to begin and planning matters. In 2020, there were 286.9 million cars registered in America. In 2020, while the US grid had 1,117.5TW of utility electricity capacity and 27.7GW of solar, according to the US Energy Information Administration. If all the cars were EVs charging at 7kW, they would need 2,008.3TW – nearly twice the grid capacity. If they charged at 50kW, they would need 14,345TW – 12.8 times the capacity.

However, in 2020, the US grid generated 4,007TWh of electricity. Americans drive further on average than Brits – 13,500 miles per year, according to the US Department of Transport’s Federal Highway Administration. That means an American car, if it were an EV, would need 3,857kWh per year, assuming the average efficiency figures above. If all US cars were EVs, they would need a total of 1,106.6TWh, which is 27.6% of what the American grid produced in 2020. US electricity consumption hasn’t shrunk in the same way since 2005 as it has in the UK, but it is clearly not unfeasible for all American cars to be EVs. The US grid could cope too, even as state power grids face challenges during the transition.

After all, the transition to electric isn’t going to happen overnight. The sales of EVs are growing fast, with for example more plug-ins sold in the UK in 2021 so far than the whole of the previous decade (2010-19) put together. Battery-electric vehicles are closing in on 10% of the market in the UK, and they were already 77.5% of new cars sold in Norway in September 2021. But that is new cars, leaving the vast majority of cars on the road fossil fuel powered. A gradual introduction is essential, too, because an overnight switchover would require a massive ramp up in charge point installation, particularly devices for people who don’t have the luxury of home charging. This will require considerable investment, but could be served by lots of chargers on street lamps, which allegedly only cost £1,000 ($1,300) each to install, usually with no need for extra wiring.

This would be a perfectly viable way to provide charging for most people. For example, as I write this article, my own EV is attached to a lamppost down the street from my house. It is receiving 5.5kW costing 24p (32 cents) per kWh through SimpleSocket, a service run by Ubitricity (now owned by Shell) and installed by my local London council, Barnet. I plugged in at 11am and by 7.30pm, my car (which was on about 28% when I started) will have around 275 miles of range – enough for a couple more weeks. It will have cost me around £12 ($16) – way less than a tank of fossil fuel. It was a super-easy process involving the scanning of a QR code and entering of a credit card, very similar to many parking systems nowadays. If most lampposts had one of these charging plugs, not having off-street parking would be no problem at all for owning an EV.

With most EVs having a range of at least 200 miles these days, and the average mileage per day being 20 miles in the UK (the 7,400-mile annual figure divided by 365 days) or 37 miles in the USA, EVs won’t need charging more than once a week or even every week or two. On average, therefore, the grids in most developed nations will be fine. The important consideration is to balance the load, because if too many EVs are charging at once, there could be a problem, and some regions like California are looking to EVs for grid stability as part of the solution. This will be a matter of incentivizing charging during off-peak times such as at night, or making peak charging more expensive. It might also be necessary to have the option to reduce charging power rates locally, while providing the ability to prioritize where necessary – such as emergency services workers. But the problem is one of logistics, not impossibility.

There will be grids around the world that are not in such a good place for an EV revolution, at least not yet, and some critics argue that policies like Canada's 2035 EV mandate are unrealistic. But to argue that widespread EV adoption will be an insurmountable catastrophe for electricity supply in developed nations is just plain wrong. So long as the supply is managed correctly to make use of spare capacity when it’s available as much as possible, the grids will cope just fine.

US utilities COVID-19 resilience shows electric utilities maintaining demand stability, reaffirming earnings guidance, and accessing the bond market for low-cost financing, as Dominion, NextEra, and Con Edison manage recession risks.

Key Points

It is the sector's capacity to sustain demand, financing access, and guidance despite pandemic recession pressures.

✅ Bond market access locks in low-cost, long-term debt

✅ Stable residential load offsets industrial weakness

✅ Guidance largely reaffirmed by major utilities

Dominion Energy (D) expects "incremental residential load" gains, consistent with COVID-19 electricity demand patterns, as a result of COVID-19 fallout. Southern Company CEO Tom Fanning says his company is "nowhere near" a need to review earnings guidance because of a potential recession, in a region where efficiency and demand response can help level electricity demand for years.

Sempra Energy (SRE) has reaffirmed earnings per share guidance for 2020 and 2021, as well timing for the sale of assets in Chile and Peru, and peers such as Duke Energy's renewables plan have reaffirmed capital investments to deliver cleaner energy and economic growth. And Xcel Energy (XEL) says it still "hasn’t seen material impact on its business."

Several electric utilities have demonstrated ability to tap the bond market, in line with utility sector trends in recent years, to lock in low-cost financing, as America moves toward broader electrification, despite ongoing turmoil. Their ranks include Dominion Energy, renewable energy leader NextEra Energy (NEE) and Consolidated Edison (ED), which last week sold $1 billion of 30-year bonds at a coupon rate of just 3.95 percent.

It’s still early days for US COVID-19 fallout. And most electric companies have yet to issue guidance. That’s understandable, since so much is still unknown about the virus and the damage it will ultimately do to human health and the global economy. But so far, the US power industry is showing typical resilience in tough times, as it coordinates closely with federal partners to maintain reliability.

Will it last? We won’t know for certain until there’s a lot more data. NextEra is usually first to report its Q1 earnings reports and detailed guidance. But that’s not expected until April 23. And companies may delay financials further, should the virus and efforts to control it impede collection and analysis of data, and as they address electricity shut-off risks affecting customers.

Hydro-Québec Carillon Refurbishment delivers a $750M hydropower modernization, replacing six turbines and upgrading civil works, water passageways, and grid equipment to extend run-of-river, renewable energy output for peak demand near Montréal.

Key Points

A $750M project replacing six units and upgrading civil, water and electrical systems to supply power for 50 years.

✅ Replaces six generating units with Andritz turbines.

✅ Upgrades civil works, water passageways, and electrical gear.

✅ Extends run-of-river output for 50 years; boosts peak supply.

Hydro-Québec will invest $750 million to refurbish its Carillon generating station with a major powerhouse upgrade that will mainly replace six generating units. The investment also covers the cost of civil engineering work, including making adjustments to water passageways, upgrading electrical equipment and replacing the station roof. Work will start in 2021, aligning with Hydro-Québec's capacity expansion plans for 2021, and continue until 2027.

Carillon generating station is a run-of-river power plant consisting of 14 generating units with a total installed capacity of 753 MW. Built in the early 1960s, it is a key part of Hydro-Québec's hydroelectric generating fleet, which includes the La Romaine complex as well. The station is close to the greater Montréal area and feeds power into the grid to support industrial demand growth during peak consumption periods.

The selected supplier, turbine manufacturer Andritz, has been asked to maximize the project's economic spinoffs in Québec, as Canada continues investing in new turbines across the country to modernize assets. Once the work is completed, the new generating units will be able to provide clean, renewable energy, supporting Hydro-Québec's strategy to reduce fossil fuel reliance for the next 50 years.

"Carillon generating station is a symbol of our hydroelectric development and plays a strategic role in our production fleet. However, most of the generating units' main components date back to the station's original construction from 1959 to 1962. Hydropower generating stations have long service lives - with this refurbishment, Carillon will be producing clean renewable energy for decades to come." said David Murray, Chief Innovation Officer and President, Hydro-Québec Production.

"In light of today's economic situation, this is an important announcement that clearly reaffirms Hydro-Québec's role in relaunching Québec's economy and strengthening interprovincial electricity partnerships that open new markets. Over 600,000 hours of work will be required for everything from the engineering work to component assembly, creating many new high-quality skilled jobs for Québec industries."

Hurricane Ida New Orleans Infrastructure faced a split outcome: levees and pumps protected against storm surge, while the power grid collapsed as transmission lines failed, prompting large-scale restoration efforts across Louisiana and Mississippi.

Key Points

It summarizes Ida's impact: levees and pumps held, but the power grid failed, causing outages and slow restoration.

✅ Levees and pumps mitigated flooding and storm surge impacts.

✅ All transmission lines failed, crippling the power grid.

✅ Crews and drones assess damage; restoration may take weeks.

Infrastructure in the city of New Orleans turned in a mixed performance against the fury of Hurricane Ida, with the levees and pumps warding off catastrophic flooding even as the electrical grid, part of the broader Louisiana power grid, failed spectacularly.

Ida’s high winds, measuring 150 miles (240 kilometers) an hour at landfall, took out all eight transmissions lines that deliver power into New Orleans, ripped power poles in half and crumpled at least one steel transmission tower into a twisted metal heap, knocking out electricity to all of the city. A total of more than 1.2 million homes and businesses in Louisiana and Mississippi lost power. While about 90,000 customers were reconnected by Monday afternoon, many could face days without electricity, and frustration can mount as seen during the Houston outage after major storms.

In contrast, the New Orleans area’s elaborate flood defenses seem to have held up, a vindication of the Army Corps of Engineers’ $14.5 billion project to rebuild levees, flood gates and pumps in the wake of the devastation wrought by Hurricane Katrina in 2005. While there were reports of scattered deaths tied to Ida, the city escaped the kind of flooding that destroyed entire neighborhoods in Katrina’s wake, left parts of the city uninhabitable for months and claimed 1,800 lives. 

“The situation in New Orleans, as bad as it is today with the power, could be so much worse,” Louisiana Governor John Bel Edwards said Monday on the Today Show, praising the levee system’s performance. “All you have to do is go back 16 years to get a glimpse of what that would have been like.”

While the levees’ resiliency is no doubt due to the rebuilding effort that followed Katrina, the starkly different outcomes also stems from the storms’ different characteristics. Katrina slammed the coast with a 30-foot storm surge of ocean water, while preliminary estimates from Ida put its surge far lower. 

Ida’s winds, however, were stronger than Katrina’s, and that’s what ultimately took out so many power lines, a dynamic that also saw Texas utilities struggle during Harvey. Deanna Rodriguez, the chief executive officer of power provider Entergy New Orleans, declined to comment on when service would be restored, saying the company was using helicopters and drones to help assess the damage.

Michael Webber, an energy and engineering professor at the University of Texas at Austin, estimated power restoration will take days and possibly weeks, a pattern seen in Florida restoration timelines after major hurricanes, based on the initial damage reports from the storm. More than 25,000 workers from at least 32 states and Washington are mobilized to assist with power restoration efforts, similar to FPL's massive response after Irma, according to the Edison Electric Institute.

“The question is, how long will it take to rebuild these lines,” Webber said. The utilities will first need to complete their damage assessments before they can get a sense of repair timelines, a step that Gulf Power crews have highlighted in past recoveries, he said. “You can imagine that will take days at least, possibly weeks.”

The loss of electricity will have other affects as well, and even though grid resilience during the pandemic was strong, local systems face immediate constraints. Sewer substations, for example, need electricity to keep wastewater moving, said Ghassan Korban, executive director of the New Orleans Sewerage & Water Board. The storm knocked out power to about 80 of the city’s 84 pumping stations, he said at a Monday press conference. “Without electricity, wastewater backs up and can cause overflows,” he said, adding that residents should conserve water to lessen stress on the system.
