The U.S. Department of Energy took a stand against electricity blackouts by giving utility companies the ability to override local opposition to power lines.
DOE announced that Virginia, Washington, D.C., and six other states are now part of a Mid-Atlantic corridor, where electricity congestion is a "significant" problem. The department on ensured that federal regulations would now keep that power flowing.
"The goal is simple - to keep reliable supplies of electric energy flowing to all Americans," said Secretary of Energy Samuel W. Bodman in a statement. The designation encourages utilities to "take prompt action," Bodman said.
The Mid-Atlantic region was named one of two National Interest Electric Transmission Corridors where the federal government could override state and local opposition to power line construction.
The other corridor includes California and Arizona. Opponents of the corridors testified at a DOE hearing in April, saying the corridors make the state process of applying for transmission lines irrelevant. Wolf, Rep. Tom Davis, R-11th, and Rep. Maurice Hinchey, D-N.Y., said they are working to strip the government of the power to overrule state decision-making. Dominion has an application to build a transmission line from West Virginia to Loudoun County under current Virginia State Corporation Commission review.
Now that Virginia is included in the corridor, if the SCC doesn't approve Dominion's application within a year, the utility company can apply to the Federal Energy Regulatory Commission for approval to build the high-voltage line.
Earlier this year, a Dominion spokesman said Dominion wouldn't resort to using the national corridor designation because the company would likely be successful in the state application process. Opponents of that power line were disappointed with the DOE decision.
"People from Watertown, New York, through Long Island, all of New Jersey, Delaware, Maryland, and counties in Virginia, Ohio and West Virginia are at risk of utilities using the federal government as their conduit to import coal electricity through places that won't even receive it," said Robert Lazaro, spokesman for the Piedmont Environmental Council.
The PEC has taken a firm stance against the Dominion proposal, saying the electricity company should work to increase efficiency instead of building power lines. So has Rep. Frank Wolf, R-10th. Both said it seems the DOE did not consider public opposition to the corridors. A DOE news release says the department considered more than 2,000 comments from 60 public hearings across the country.
"(The corridor designation) makes no sense and has the potential to destroy neighborhoods and desecrate huge swaths of historically significant land," Wolf said in a statement. "The fact that power companies will continue to be able to ignore the need for increased conservation and smart technology remains extremely troublesome."
Dominion defends its application by citing increased electricity demand by 2011 - so much that the region could face blackouts without the addition to its electricity transmission network.
DOE's corridor designation aims to prevent those blackouts by helping utilities gain approval for transmission line construction permits. Dominion aims to finish construction of the transmission lines by June 2011. The NIETC in Virginia includes Manassas, Manassas Park, Alexandria, Harrisonburg, Fairfax, Falls Church and Winchester, and Prince William, Arlington, Clarke, Culpeper, Fairfax, Fauquier, Frederick, Loudoun, Madison, Page, Rappahannock, Rockingham, Shenandoah, Stafford and Warren counties. Both point to the Northeast blackout of 2003 as the impetus for building more lines.
On Aug. 14, 2003, more than 50 million people were left without power due to utility company failures, some of which were against industry recommendations.
Phyllis Dodson, whose property in Fauquier County lies in a proposed power line path, said she's hopeful. "We are still confident that we can win the battle at both levels and no more above ground transmission lines will be built through our beautiful countryside," Dodson said. "There are groups working on several fronts to stop this plan."
ITER Nuclear Fusion advances tokamak magnetic confinement, heating deuterium-tritium plasma with superconducting magnets, targeting net energy gain, tritium breeding, and steam-turbine power, while complementing laser inertial confinement milestones for grid-scale electricity and 2025 startup goals.
Key Points
ITER Nuclear Fusion is a tokamak project confining D-T plasma with magnets to achieve net energy gain and clean power.
✅ Tokamak magnetic confinement with high-temp superconducting coils
✅ Deuterium-tritium fuel cycle with on-site tritium breeding
✅ Targets net energy gain and grid-scale, low-carbon electricity
It sounds like the stuff of dreams: a virtually limitless source of energy that doesn’t produce greenhouse gases or radioactive waste. That’s the promise of nuclear fusion, often described as the holy grail of clean energy by proponents, which for decades has been nothing more than a fantasy due to insurmountable technical challenges. But things are heating up in what has turned into a race to create what amounts to an artificial sun here on Earth, one that can provide power for our kettles, cars and light bulbs.
Today’s nuclear power plants create electricity through nuclear fission, in which atoms are split, with next-gen nuclear power exploring smaller, cheaper, safer designs that remain distinct from fusion. Nuclear fusion however, involves combining atomic nuclei to release energy. It’s the same reaction that’s taking place at the Sun’s core. But overcoming the natural repulsion between atomic nuclei and maintaining the right conditions for fusion to occur isn’t straightforward. And doing so in a way that produces more energy than the reaction consumes has been beyond the grasp of the finest minds in physics for decades.
But perhaps not for much longer. Some major technical challenges have been overcome in the past few years and governments around the world have been pouring money into fusion power research as part of a broader green industrial revolution under way in several regions. There are also over 20 private ventures in the UK, US, Europe, China and Australia vying to be the first to make fusion energy production a reality.
“People are saying, ‘If it really is the ultimate solution, let’s find out whether it works or not,’” says Dr Tim Luce, head of science and operation at the International Thermonuclear Experimental Reactor (ITER), being built in southeast France. ITER is the biggest throw of the fusion dice yet.
Its $22bn (£15.9bn) build cost is being met by the governments of two-thirds of the world’s population, including the EU, the US, China and Russia, at a time when Europe is losing nuclear power and needs energy, and when it’s fired up in 2025 it’ll be the world’s largest fusion reactor. If it works, ITER will transform fusion power from being the stuff of dreams into a viable energy source.
Constructing a nuclear fusion reactor ITER will be a tokamak reactor – thought to be the best hope for fusion power. Inside a tokamak, a gas, often a hydrogen isotope called deuterium, is subjected to intense heat and pressure, forcing electrons out of the atoms. This creates a plasma – a superheated, ionised gas – that has to be contained by intense magnetic fields.
The containment is vital, as no material on Earth could withstand the intense heat (100,000,000°C and above) that the plasma has to reach so that fusion can begin. It’s close to 10 times the heat at the Sun’s core, and temperatures like that are needed in a tokamak because the gravitational pressure within the Sun can’t be recreated.
When atomic nuclei do start to fuse, vast amounts of energy are released. While the experimental reactors currently in operation release that energy as heat, in a fusion reactor power plant, the heat would be used to produce steam that would drive turbines to generate electricity, even as some envision nuclear beyond electricity for industrial heat and fuels.
Tokamaks aren’t the only fusion reactors being tried. Another type of reactor uses lasers to heat and compress a hydrogen fuel to initiate fusion. In August 2021, one such device at the National Ignition Facility, at the Lawrence Livermore National Laboratory in California, generated 1.35 megajoules of energy. This record-breaking figure brings fusion power a step closer to net energy gain, but most hopes are still pinned on tokamak reactors rather than lasers.
In June 2021, China’s Experimental Advanced Superconducting Tokamak (EAST) reactor maintained a plasma for 101 seconds at 120,000,000°C. Before that, the record was 20 seconds. Ultimately, a fusion reactor would need to sustain the plasma indefinitely – or at least for eight-hour ‘pulses’ during periods of peak electricity demand.
A real game-changer for tokamaks has been the magnets used to produce the magnetic field. “We know how to make magnets that generate a very high magnetic field from copper or other kinds of metal, but you would pay a fortune for the electricity. It wouldn’t be a net energy gain from the plant,” says Luce.
One route for nuclear fusion is to use atoms of deuterium and tritium, both isotopes of hydrogen. They fuse under incredible heat and pressure, and the resulting products release energy as heat
The solution is to use high-temperature, superconducting magnets made from superconducting wire, or ‘tape’, that has no electrical resistance. These magnets can create intense magnetic fields and don’t lose energy as heat.
“High temperature superconductivity has been known about for 35 years. But the manufacturing capability to make tape in the lengths that would be required to make a reasonable fusion coil has just recently been developed,” says Luce. One of ITER’s magnets, the central solenoid, will produce a field of 13 tesla – 280,000 times Earth’s magnetic field.
The inner walls of ITER’s vacuum vessel, where the fusion will occur, will be lined with beryllium, a metal that won’t contaminate the plasma much if they touch. At the bottom is the divertor that will keep the temperature inside the reactor under control.
“The heat load on the divertor can be as large as in a rocket nozzle,” says Luce. “Rocket nozzles work because you can get into orbit within minutes and in space it’s really cold.” In a fusion reactor, a divertor would need to withstand this heat indefinitely and at ITER they’ll be testing one made out of tungsten.
Meanwhile, in the US, the National Spherical Torus Experiment – Upgrade (NSTX-U) fusion reactor will be fired up in the autumn of 2022, while efforts in advanced fission such as a mini-reactor design are also progressing. One of its priorities will be to see whether lining the reactor with lithium helps to keep the plasma stable.
Choosing a fuel Instead of just using deuterium as the fusion fuel, ITER will use deuterium mixed with tritium, another hydrogen isotope. The deuterium-tritium blend offers the best chance of getting significantly more power out than is put in. Proponents of fusion power say one reason the technology is safe is that the fuel needs to be constantly fed into the reactor to keep fusion happening, making a runaway reaction impossible.
Deuterium can be extracted from seawater, so there’s a virtually limitless supply of it. But only 20kg of tritium are thought to exist worldwide, so fusion power plants will have to produce it (ITER will develop technology to ‘breed’ tritium). While some radioactive waste will be produced in a fusion plant, it’ll have a lifetime of around 100 years, rather than the thousands of years from fission.
At the time of writing in September, researchers at the Joint European Torus (JET) fusion reactor in Oxfordshire were due to start their deuterium-tritium fusion reactions. “JET will help ITER prepare a choice of machine parameters to optimise the fusion power,” says Dr Joelle Mailloux, one of the scientific programme leaders at JET. These parameters will include finding the best combination of deuterium and tritium, and establishing how the current is increased in the magnets before fusion starts.
The groundwork laid down at JET should accelerate ITER’s efforts to accomplish net energy gain. ITER will produce ‘first plasma’ in December 2025 and be cranked up to full power over the following decade. Its plasma temperature will reach 150,000,000°C and its target is to produce 500 megawatts of fusion power for every 50 megawatts of input heating power.
“If ITER is successful, it’ll eliminate most, if not all, doubts about the science and liberate money for technology development,” says Luce. That technology development will be demonstration fusion power plants that actually produce electricity, where advanced reactors can build on decades of expertise. “ITER is opening the door and saying, yeah, this works – the science is there.”
Northern Pass Project faces rejection by New Hampshire regulators, halting Hydro-Quebec clean energy transmission lines to Massachusetts; Eversource vows appeal as the Site Evaluation Committee cites development concerns and alternative routes through Vermont and Maine.
Key Points
A project to transmit Hydro-Quebec power to Massachusetts via New Hampshire, recently rejected by state regulators.
✅ New Hampshire SEC denied the transmission application
✅ Up to 9.45 TWh yearly from Hydro-Quebec to Massachusetts
✅ Eversource plans appeal; alternative routes via Vermont, Maine
Regulators in the state of New Hampshire on Thursday rejected a major electricity project being piloted by Quebec’s hydro utility and its American partner, Eversource.
Members of New Hampshire’s Site Evaluation Committee unanimously denied an application for the Northern Pass project a week after the state of Massachusetts green-lit the proposal.
Both states had to accept the project, as the transmission lines were to bring up to 9.45 terawatt hours of electricity per year from Quebec’s hydroelectric plants to Massachusetts as part of Hydro-Quebec’s export bid to New England, through New Hampshire.
The 20-year proposal was to be the biggest export contract in Hydro-Quebec’s history, in a region where Connecticut is leading a market overhaul that could affect pricing, and would generate up to $500 million in annual revenues for the provincial utility.
Hydro-Quebec’s U.S. partner, Eversource, said in a new release it was “shocked and outraged” by the New Hampshire regulators’ decision and suggested it would appeal.
“This decision sends a chilling message to any energy project contemplating development in the Granite State,” said Eversource. “We will be seeking reconsideration of the SEC’s decision, as well as reviewing all options for moving this critical clean energy project forward, including lessons from electricity corridor construction in Maine.”
The New Hampshire Union Leader reported Thursday the seven members of the evaluation committee said the project’s promoters couldn’t demonstrate the proposed energy transport lines wouldn’t interfere with the region’s orderly development.
Hydro-Quebec spokesman Serge Abergel said the decision wasn’t great news but it didn’t put a end to the negotiations between the company and the state of Massachusetts.
The hydro utility had proposed alternatives routes through Vermont and Maine amid a 145-mile transmission line debate over the corridor should the original plan fall through.
“There is a provision included in the process in the advent of an impasse, which allows Massachusetts to go back and choose the next candidate on the list,” Abergel said in an interview. “There are still cards left on the table.”
Nova Scotia Biomass Energy faces scrutiny as hydropower from Muskrat Falls via the Maritime Link increases, raising concerns over carbon emissions, biodiversity, ratepayer costs, and efficiency versus district heating in the province's renewable mix.
Key Points
Electricity from wood chips and waste wood in Nova Scotia, increasingly questioned as hydropower from the Maritime Link grows.
✅ Hydropower deliveries reduce need for biomass on the grid
✅ Biomass is inefficient, costly, and impacts biodiversity
✅ District heating offers better use of forestry residuals
The Ecology Action Centre's senior wilderness coordinator is calling on the Nova Scotia government to reduce the use of biomass to generate electricity now that more hydroelectric power is flowing into the province.
In 2020, the government of the day signed a directive for Nova Scotia Power to increase its use of biomass to generate electricity, including burning more wood chips, waste wood and other residuals from the forest industry. At the time, power from Muskrat Falls hydroelectric project in Labrador was not flowing into the province at high enough levels to reach provincial targets for electricity generated by renewable resources.
In recent months, however, the Maritime Link from Muskrat Falls has delivered Nova Scotia's full share of electricity, and, in some cases, even more, as the province also pursues Bay of Fundy tides projects to diversify supply.
Ray Plourde with the Ecology Action Centre said that should be enough to end the 2020 directive.
Ray Plourde is senior wilderness coordinator for the Ecology Action Centre. (CBC) Biomass is "bad on a whole lot of levels," said Plourde, including its affects on biodiversity and the release of carbon into the atmosphere, he said. The province's reliance on waste wood as a source of fuel for electricity should be curbed, said Plourde.
"It's highly inefficient," he said. "It's the most expensive electricity on the power grid for ratepayers."
A spokesperson for the provincial Natural Resources and Renewables Department said that although the Maritime Link has "at times" delivered adequate electricity to Nova Scotia, "it hasn't done so consistently," a context that has led some to propose an independent planning body for long-term decisions.
"These delays and high fossil fuel prices mean that biomass remains a small but important component of our renewable energy mix," Patricia Jreiga said in an email, even as the province plans to increase wind and solar projects in the years ahead.
But to Plourde, that explanation doesn't wash.
The Nova Scotia Utility and Review Board recently ruled that Nova Scotia Power could begin recouping costs of the Maritime Link project from ratepayers. As for the rising cost of fossil fuels, Ploude noted that the inefficiency of biomass means there's no deal to be had using it as a fuel source.
"Honestly, that sounds like a lot of obfuscation," he said of the government's position.
No update on district heating plans At the time of the directive, government officials said the increased use of forestry byproducts at biomass plants in Point Tupper and Brooklyn, N.S., including the nearby Port Hawkesbury Paper mill, would provide a market for businesses struggling to replace the loss of Northern Pulp as a customer. Brooklyn Power has been offline since a windstorm damaged that plant in February, however. Repairs are expected to be complete by the end of the year or early 2023.
Ploude said a better use for waste wood products would be small-scale district heating projects, while others advocate using more electricity for heat in cold regions.
Although the former Liberal government announced six public buildings to serve as pilot sites for district heating in 2020, and a list of 100 other possible buildings that could be converted to wood heat, there have been no updates.
"Currently, we're working with several other departments to complete technical assessments for additional sites and looking at opportunities for district heating, but no decisions have been made yet," provincial spokesperson Steven Stewart said in an email.
Birtle Transmission Line connects Manitoba Hydro to SaskPower, enabling 215 MW of clean hydroelectricity, improving grid reliability, supporting affordable rates, and advancing Green Infrastructure goals under the Investing in Canada Plan across Manitoba and Saskatchewan.
Key Points
A 46 km line moving up to 215 MW from Manitoba Hydro to SaskPower, improving reliability and supplying cleaner power.
✅ Enables interprovincial grid tie between Manitoba and Saskatchewan
✅ Delivers up to 215 MW of renewable hydroelectricity
✅ Supports affordable rates and lower GHG emissions
The federal government announced funding for the Birtle Transmission Line Monday morning.
The project will help Manitoba Hydro build a transmission line from Birtle South Station in the Municipality of Prairie View to the Manitoba–Saskatchewan border 46 kilometres northwest. Once completed, the new line will allow up to 215 megawatts of hydroelectricity to flow from the Manitoba Hydro power grid to the SaskPower power grid, similar to the Great Northern Transmission Line connecting Manitoba and Minnesota today.
The government said the transmission line would create a more stable energy supply, keep energy rates affordable and help Saskatchewan's efforts to reduce cumulative greenhouse-gas emissions in that province.
"The Government of Canada is proud to be working with Manitoba to support projects that create jobs and improve people's lives across the province. The Birtle Transmission Line will provide the region with reliable and greener energy, as seen with Canadian hydropower to New York projects, that will help protect our environment while laying the groundwork for clean economic growth," said Jim Carr, member of Parliament for Winnipeg South Centre, on behalf of Catherine McKenna, minister of infrastructure and communities.
The Government of Canada is investing more than $18.7 million, and the government of Manitoba is contributing more than $42 million in this project through the Green Infrastructure Stream of the Investing in Canada Plan, which also supports Atlantic grid improvements nationwide.
"The Province of Manitoba has one of the cleanest electricity grids in Canada and the world with over 99 per cent of our electricity generated from clean, renewable sources, rooted in Manitoba's hydro history," said Central Services Minister Reg Helwer. "The Made-in-Manitoba Climate and Green Plan is good not only for Manitoba but for Canada and globally."
Jay Grewal, president, and CEO of Manitoba Hydro said the funding is a great example of co-operation between the provincial and federal governments, including investments in smart grid technology that modernize local networks.
"We are very pleased that Manitoba Hydro's Birtle Transmission Project is among the first projects to receive funding under the Canada Infrastructure Program, and we would like to thank both levels of governments for recognizing the importance of the project as we strengthen ties with our neighbours in Saskatchewan, as U.S.-Canada transmission approvals advance elsewhere," said Grewal.
A spokesperson for Manitoba Hydro said it’s too early to say how many jobs will be created during construction, as final contracts have not yet been awarded.
NYSERDA Offshore Wind Data initiative funds geophysical and geotechnical surveys, seabed and soil studies on New York's shelf to accelerate siting, optimize foundation design, reduce costs, and advance clean energy deployment.
Key Points
State funding to support surveys and soil studies guiding offshore wind siting, design, and cost reduction.
✅ Up to $5.5M for geophysical and geotechnical data collection
✅ Focus on seabed soils, shelf geology, and foundation design inputs
✅ Accelerates siting, reduces risk, and lowers offshore wind costs
The New York State Energy Research and Development Authority (NYSERDA) is investing up to $5.5 million for the collection of geophysical and geotechnical data to determine future offshore wind development sites.
The funding is to look at seabed soil and geological data for the preliminary design and installation requirements for future offshore wind projects. Its part of N.Y. Gov. Andrew Cuomos plan to develop 9,000 megawatts of offshore wind energy by 2035.
Todays announcement is another step in Governor Cuomos steadfast march to achieving 9,000 megawatts of offshore wind by 2035, putting New York in a clear national leadership position when it comes to advancing this new industry through large-scale energy projects across the state. The surveys NYSERDA will be funding under this solicitation will expand the offshore wind industrys access to geophysical and geotechnical data that will provide the foundation for future offshore wind development in these areas, and accelerate project development while driving down costs, NYSERDA President and CEO Alicia Barton said.
NYSERDA will select one or more contractors to do the investigations, while recent DOE wind energy awards support complementary research, and develop a model for describing geophysical and geotechnical conditions. NYSERDA will also select a contractor to support project management and host the data that is collected. The submission deadline is Jan. 21, 2020.
Todays announcement builds on the data collected in a Geotechnical and Geophysical Desktop Study also released today, which includes information on the middle continental shelf off the shore of New York and New Jersey, where BOEM lease requests are shaping activity, creating a regional overview of the seafloor and sub-seafloor environment as it relates to offshore wind development.
Strong knowledge of environmental conditions and factors, including seabed soil conditions, are essential for the installation of offshore projects, such as Long Island proposals, but only a limited amount of soil sampling and testing has been undertaken to date.
The collection of geophysical and geotechnical data from areas off of New Yorks Atlantic coast is yet another demonstration of New Yorks leadership promoting the responsible development of offshore wind. The data generated by this initiative will ultimately lead to better projects, lower cost, and enhanced safety. New York is leading the way to a clean energy future, as the state finalizes renewable project contracts that expand capacity, and relying on data collection and sound science to get us there, New York Offshore Wind Alliance Director Joe Martens said.
U.S. Data Center Power Demand is straining electric utilities and grid reliability as AI, cloud computing, and streaming surge, driving transmission and generation upgrades, demand response, and renewable energy sourcing amid rising electricity costs.
Key Points
The rising electricity load from U.S. data centers, affecting utilities, grid capacity, and energy prices.
✅ AI, cloud, and streaming spur hyperscale compute loads
✅ Grid upgrades: transmission, generation, and substations
✅ Demand response, efficiency, and renewables mitigate strain
U.S. electric utilities are facing a significant new challenge as the explosive growth of data centers puts unprecedented strain on power grids across the nation. According to a new report from Reuters, data centers' power demands are expected to increase dramatically over the next few years, raising concerns about grid reliability and potential increases in electricity costs for businesses and consumers.
What's Driving the Data Center Surge?
The explosion in data centers is being fueled by several factors, with grid edge trends offering early context for these shifts:
Cloud Computing: The rise of cloud computing services, where businesses and individuals store and process data on remote servers, significantly increases demand for data centers.
Artificial Intelligence (AI): Data-hungry AI applications and machine learning algorithms are driving a massive need for computing power, accelerating the growth of data centers.
Streaming and Video Content: The growth of streaming platforms and high-definition video content requires vast amounts of data storage and processing, further boosting demand for data centers.
Challenges for Utilities
Data centers are notorious energy hogs. Their need for a constant, reliable supply of electricity places heavy demand on the grid, making integrating AI data centers a complex planning challenge, often in regions where power infrastructure wasn't designed for such large loads. Utilities must invest significantly in transmission and generation capacity upgrades to meet the demand while ensuring grid stability.
Some experts warn that the growth of data centers could lead to brownouts or outages, as a U.S. blackout study underscores ongoing risks, especially during peak demand periods in areas where the grid is already strained. Increased electricity demand could also lead to price hikes, with utilities potentially passing the additional costs onto consumers and businesses.
Sustainable Solutions Needed
Utility companies, governments, and the data center industry are scrambling to find sustainable solutions, including using AI to manage demand initiatives across utilities, to mitigate these challenges:
Energy Efficiency: Data center operators are investing in new cooling and energy management solutions to improve energy efficiency. Some are even exploring renewable energy sources like onsite solar and wind power.
Strategic Placement: Authorities are encouraging the development of data centers in areas with abundant renewable energy and access to existing grid infrastructure. This minimizes the need for expensive new transmission lines.
Demand Flexibility: Utility companies are experimenting with programs as part of a move toward a digital grid architecture to incentivize data centers to reduce their power consumption during peak demand periods, which could help mitigate power strain.
The Future of the Grid
The rapid growth of data centers exemplifies the significant challenges facing the aging U.S. electrical grid, with a recent grid report card highlighting dangerous vulnerabilities. It highlights the need for a modernized power infrastructure, capable of accommodating increasing demand spurred by new technologies while addressing climate change impacts that threaten reliability and affordability. The question for utilities, as well as data center operators, is how to balance the increasing need for computing power with the imperative of a sustainable and reliable energy future.
