Another chance for Quebec hydro-power line into New England
Adapted from Robert Whitcomb’s Digital Diary, in GoLocal24.com
It looked like the long-delayed power line to run from hydro-electric generation in Quebec (comfortably close to us) into the New England grid was kaput after a legally dubious referendum in Maine blocked the line. The project is called New England Clean Energy Connect.
But the Maine Supreme Judicial Court held last month that important sections of the law enacted by the referendum were unconstitutional because they deprived the company building the line -- Avangrid -- of rights that had already been legally vested before the vote. In short, the justices opposed the retroactive nature of the referendum.
Now the case goes back to a lower court for review.
Note that well-funded opposition to New England Clean Energy Connect includes such still fossil-fuel-heavy companies as NextEra Energy, which naturally see the power line as threatening their businesses.
The story is far from over, but in a world of accelerating global warming and countries held hostage by corrupt dictatorships financed by natural gas and oil, the Maine decision is a glimmer of good news.
Llewellyn King: Utilities urgently need to add transmission

It has become second nature. You hear that bad weather is coming and rush to the store to stock up on bottled water and canned and other non-perishable foods. You check your flashlight batteries.
For a few days, we are all survivalists. Why? Because we are resigned to the idea that bad weather equates with a loss of electrical power.
What happens is the fortunate have emergency generators hooked up to their freestanding houses. The rest of us just hope for the best, but with real fear of days without heat.
It happened most severely in Texas in February 2021; during Winter Storm Uri, which lasted five days, 250 people died. Recently, during the Blizzard of 2022, on Jan. 28-29, 100,000 people in Massachusetts endured bitter cold nights when the electricity failed. There were more power failures in the most recent ice storm.
There are 3,000 electric utilities in the United States. Sixty large ones, like Consolidated Edison, NextEra Energy, Pacific Gas and Electric, and the Tennessee Valley Authority, supply 70 percent of the nation’s electricity. Nonetheless, the rest are critical in their communities.
All utilities, large and small, have much in common: They are all under pressure to replace coal and natural gas generation with renewables, which means solar and wind. No new, big hydro is planned, and nuclear is losing market share as plants go out of service because they are too expensive to operate.
The word the utilities like to use is resilience. It means that they will do their best to keep the lights on and to restore power as fast as possible if they fail due to bad weather. When those events threaten, the utilities spring into action, dispatching crews to each other’s trouble spots as though they were ordering up the cavalry. The utilities have become very proactive, but if storms are severe, it often isn’t enough.
Now, besides more frequent severe weather events, utilities face the possibility of destabilization on another front, due to switching to renewables before new storage and battery technology is available or deployed.
The first step to avoid new instability -- and it is a critical one -- is to add transmission. This would move electricity from where it is generated in wind corridors and sun-drenched states to where the demand is, often in a different time zone.
Duane Highley, president and CEO of Tri-State Generation and Transmission Association, which serves four states in the West from its base in Westminster, Colo., says new west-east and east-west transmission is critical to take the power from the resource-rich Intermountain states to the population centers in the East and to California.
“Most existing transmission lines run north to south. They aren’t getting the renewables to the load centers,” Highley says.
Echoing this theme, Alice Moy-Gonzalez, senior vice president of strategic development at Anterix, a communications company providing broadband private networks that make the grid more secure and efficient, sees pressure on the grid from renewables and from new customer demands (such as electrical vehicles) as electrification spreads throughout society.
“The use of advanced secure communications to monitor all of these resources and coordinate their operation will be key to maintaining reliability and optimization as we modernize the grid,” Moy-Gonzalez says.
Better communications are one step in the way forward, but new lines are at the heart of the solution.
The Biden administration, as part of its infrastructure plan, has singled out the grid for special attention under the rubric “Build a Better Grid.” It has also earmarked $20 billion of already appropriated funds to get the ball rolling.
Industry lobbyists in Washington say they have the outlines of the Department of Energy plan, but details are slow to emerge. Considered particularly critical is the administration’s commitment to ease and coordinate siting obstacles with the states and affected communities.
Utilities are challenged to increase the resilience of the grid they have and to expand it before it becomes more unstable.
Clint Vince, who heads the U.S. energy practice at Dentons, the world’s largest law firm, says, “We aren’t going to reach the growth in renewables needed to address climate without exponential growth in major interstate transmission. And sadly, we won’t succeed with that goal on our current trajectory. We will need significant federal intervention because collaboration among the states simply hasn’t been working within the timeframe needed.”
Better keep the flashlights handy.

Meredith Angwin: New Englanders should get ready for rolling blackouts

WILDER, Vt.
Rolling blackouts are probably coming to New England sooner than expected.
When there’s not enough supply of electricity to meet demand, an electric grid operator cuts power to one section of the grid to keep the rest of the grid from failing. After a while, the operator restores the power to the blacked-out area and moves the blackout on to another section. The New England grid operator (ISO-NE) recently completed a major study of various scenarios for the near-term future (2024-2025) of the grid, including the possibilities of rolling blackouts. (ISO stands for Independent System Operator.)
In New England, blackouts are expected to occur during the coldest weather, because that is when the grid is most stressed. Rolling blackouts add painful uncertainty – and danger – to everyday life. You aren’t likely to know when a blackout will happen, because most grid operators have a policy that announcing a blackout would attract crime to the area.
Exelon announces plan to close Mystic Station
In early April, Exelon said that it would close two large natural-gas-fired units at Mystic Station, in Everett, Mass. In its report about possibilities for the winter of 2024-25, ISO-NE had included the loss of these two plants as one of its scenarios. The ISO-NE report concluded that Mystic’s possible closure would lead to 20 to 50 hours of load shedding (rolling blackouts) and hundreds of hours of grid operation under emergency protocols.
When Exelon made its closure announcement, ISO-NE realized that the danger of rolling blackouts was suddenly more immediate than 2024. ISO-NE now hopes to grant “out of market cost recovery” (that is, subsidies) to persuade Exelon to keep the Mystic plants operating. If ISO-NE gets FERC permission for the subsidies, some of the threat of blackouts will retreat a few years into the future.
Winter scenarios and natural gas
The foremost challenge to grid reliability is the inability of power plants to get fuel in winter. So ISO-NE modeled various scenarios, such as winter-long outages at key energy facilities, and difficulty or ease of delivering Liquified Natural Gas (LNG) to existing plants.
Ominously, 19 of the 23 of the ISO-NE scenarios led to rolling blackouts. The worst scenarios, with the longest blackouts, included a long outage at a nuclear plant or a long-lasting failure of a gas pipeline compressor.
A major cause of these grid problems is that the New England grid is heavily dependent on natural gas. Power plants using natural gas supply about 50 percent of New England’s electricity on a year-round basis. Pipelines give priority to delivering gas for home heating over delivering gas to power plants. In the winter, some power plants cannot get enough gas to operate. Other fuels have to take up the slack. But coal and nuclear generators are retiring, and with them goes needed capacity. In general, the competing-for-natural-gas problem will get steadily worse over time.
All the ISO-NE scenarios assumed that no new oil, coal, or nuclear plants are built, some existing plants will close, and no new pipelines are constructed. Their scenarios included renewable buildouts, transmission line construction, increased delivery of LNG, plant outages and compressor outages.
Natural gas and LNG
The one “no-problem” scenario (no load shedding, no emergency procedures) is one where everything goes right. It assumed no major pipeline or power plant outages. It included a large renewable buildout plus greatly increased LNG delivery, despite difficult winter weather. This no-problem scenario also assumes a minimum number of retirements of coal, oil and nuclear plants.
This positive scenario is dependent on increased LNG deliveries from abroad. Thanks to the Jones Act, New England cannot obtain domestic LNG. There are no LNG carriers flying an American flag, and the Jones Act prevents foreign carriers from delivering American goods to American ports.
We can plan to import more electricity, but ISO-NE notes that such imports are also problematic. Canada has extreme winter weather (and curtails electricity exports) at the same time that New England has extreme weather and a stressed grid.
New England needs a diverse grid
To avoid blackouts, we need to diversify our energy supply beyond renewables and natural gas to have a grid that can reliably deliver power in all sorts of weather. When we close nuclear and coal plants and don’t build gas pipelines, we increase our weather-vulnerable dependency on imported LNG.
We need to keep existing nuclear, hydro, coal and oil plants available to meet peak demands, even if it takes subsidies. Coal is a problem fuel, but running a coal plant for a comparatively short time in bad weather is a better choice than rolling blackouts.
This can’t happen overnight. It has to be planned for. If we don’t diversify our electricity supply, we will have to get used to enduring rolling blackouts.
