U.S. Geothermal Inc., a renewable energy company focused on the production of electricity from geothermal energy, announced a progress update on the company^^s Unit One geothermal power plant at Raft River, Idaho.
Construction activities associated with the Unit One plant were completed when the power plant contractor, Ormat Nevada, achieved substantial completion under the terms of the engineering, construction and procurement contract. The plant operated under a test phase of power production from October 18 to 23.
After a number of start-up mechanical issues were successfully addressed, the plant was restarted on November 22 and is continuing operations. Plant operations are dependent upon maintaining a sufficient pressure regime in the production wells. The operating staff continues to learn about each well's capabilities and the relationship of injection pressure to production.
The test phase is ongoing to allow for a fuller understanding of the geothermal resource capability. The net electrical power output of the plant is currently between 8 and 9 megawatts. With four production wells in operation, the maximum and minimum gross electrical output achieved by the plant to date was 14.4 and 9.5 megawatts respectively.
The maximum and minimum net electrical output achieved by the plant to date was 9.4 and 7.1 megawatts respectively. The output of the plant is being sold to Idaho Power Company and sales are limited to 10 megawatts average per month under the terms of the existing power purchase agreement. The plant is designed to produce an annual average net output of 13 megawatts.
Test power sold during this period is being purchased by Idaho Power Company under the terms of a 10-megawatt Public Utility Regulatory Policies Act ("PURPA") contract. Full energy prices will be paid when the plant achieves commercial operations. Delays caused by mechanical issues have extended the date when commercial operation will be achieved to within the next fifteen days.
Pending approval by the Idaho Public Utility Commission, a recently executed full-output contract is expected to take effect and replace the existing 10-megawatt PURPA contract.
Currently, four production wells and three injection wells are in service to the power plant. To achieve full output under the pending new contract, a number of technical issues are being addressed including installation of the fifth production well, evaluation of total injection well capacity and modeling of the resource pressure and temperature regime.
Barakah Unit 4 Cold Hydrostatic Testing validates reactor coolant system integrity at the Barakah Nuclear Energy Plant in Abu Dhabi, UAE, confirming safety, quality, and commissioning readiness under ENEC and KEPCO oversight.
Key Points
Pressure test of Unit 4's reactor coolant system, confirming integrity and safety for commissioning at Barakah.
✅ 25% above normal operating pressure verified.
✅ Welds, joints, and high-pressure components inspected.
The Emirates Nuclear Energy Corporation (ENEC) has successfully completed Cold Hydrostatic Testing (CHT) at Unit 4 of the Barakah Nuclear Energy Plant, the Arab world’s first nuclear energy plant being built in the Al Dhafra region of Abu Dhabi, UAE. The testing incorporated the lessons learned from the previous three units and is a crucial step towards the completion of Unit 4, the final unit of the Barakah plant.
As a part of CHT, the pressure inside Unit 4’s systems was increased to 25 per cent above what will be the normal operating pressure, demonstrating, as seen across global nuclear projects, the quality and robust nature of the Unit’s construction. Prior to the commencement of CHT, Unit 4’s Nuclear Steam Supply Systems were flushed with demineralised water, and the Reactor Pressure Vessel Head and Reactor Coolant Pump Seals were installed. During the Cold Hydrostatic Testing, the welds, joints, pipes and components of the reactor coolant system and associated high-pressure systems were verified.
Mohammed Al Hammadi, Chief Executive Officer of ENEC said: “I am proud of the continued progress being made at Barakah despite the circumstances we have all faced in relation to COVID-19. The UAE leadership’s decisive and proactive response to the pandemic supported us in taking timely, safety-led actions to protect the health and safety of our workforce and our plant. These actions, alongside the efforts of our talented and dedicated workforce, have enabled the successful completion of CHT at Unit 4, which was completed in adherence to the highest standards of safety, quality, and security.
“With this accomplishment, we move another step closer to achieving our goal of supplying up to a quarter of our nation’s electricity needs through the national grid and powering its future growth with safe, reliable, and emissions-free electricity,” he added.
By the end of 2019, ENEC and Korea Electric Power Corporation (KEPCO), working with Korea Hydro & Nuclear Power (KHNP) on the project, had successfully completed all major construction work including major concrete pouring, installation of the Turbine Generator, and the internal components of the Reactor Pressure Vessel (RPV) of Unit 4, which paved the way for the commencement of testing and commissioning.
The testing at Unit 4 represents a significant achievement in the development of the UAE Peaceful Nuclear Energy Program, following the successful completion of fuel assembly loading into Unit 1 in March 2020, confirming that the UAE has officially become a peaceful nuclear energy operating nation. Preparations are now in the final stages for the safe start-up of Unit 1, which subsequently reached 100% power ahead of commercial operations, in the coming months.
ENEC is currently in the final stages of construction of units 2, 3 and 4 of the Barakah Nuclear Energy Plant, as China’s nuclear program continues its steady development globally. The overall construction of the four units is more than 94% complete. Unit 4 is more than 84 per cent, Unit 3 is more than 92 per cent and Unit 2 is more than 95 per cent. The four units at Barakah will generate up to 25 per cent of the UAE’s electricity demand by producing 5,600 MW of clean baseload electricity, as projects such as new reactors in Georgia take shape, and preventing the release of 21 million tons of carbon emissions each year – the equivalent of removing 3.2 million cars off the roads annually.
Toronto Electricity Demand Growth underscores IESO projections of rising peak load by 2050, driven by population growth, electrification, new housing density, and tech economy, requiring grid modernization, transmission upgrades, demand response, and local renewable energy.
Key Points
It refers to the projected near-doubling of Toronto's peak load by 2050, driven by electrification and urban growth.
✅ IESO projects peak demand nearly doubling by 2050
Toronto faces a significant challenge in meeting the growing electricity needs of its expanding population and ambitious development plans. According to a new report from Ontario's Independent Electricity System Operator (IESO), Toronto's peak electricity demand is expected to nearly double by 2050. This highlights the need for proactive steps to secure adequate electricity supply amidst the city's ongoing economic and population growth.
Key Factors Driving Demand
Several factors are contributing to the projected increase in electricity demand:
Population Growth: Toronto is one of the fastest-growing cities in North America, and this trend is expected to continue. More residents mean more need for housing, businesses, and other electricity-consuming infrastructure.
New Homes and Density: The city's housing strategy calls for 285,000 new homes within the next decade, including significant densification in existing neighbourhoods. High-rise buildings in urban centers are generally more energy-intensive than low-rise residential developments.
Economic Development: Toronto's robust economy, a hub for tech and innovation, attracts new businesses, including energy-intensive AI data centers that fuel further demand for electricity.
Electrification: The push to reduce carbon emissions is driving the electrification of transportation and home heating, further increasing pressure on Toronto's electricity grid.
Planning for the Future
Ontario and the City of Toronto recognize the urgency to secure stable and reliable electricity supplies to support continued growth and prosperity without sacrificing affordability, drawing lessons from British Columbia's clean energy shift to inform local approaches. Officials are collaborating to develop a long-term plan that focuses on:
Energy Efficiency: Efforts aim to reduce wasteful electricity usage through upgrades to existing buildings, promoting energy-efficient appliances, and implementing smart grid technologies. These will play a crucial role in curbing overall demand.
New Infrastructure: Significant investments in building new electricity generation, transmission lines, and substations, as well as regional macrogrids to enhance reliability, will be necessary to meet the projected demands of Toronto's future.
Demand Management: Programs incentivizing energy conservation during peak hours will help to avoid strain on the grid and reduce the need to build expensive power plants only used at peak demand times.
Challenges Ahead
The path ahead isn't without its hurdles. Building new power infrastructure in a dense urban environment like Toronto can be time-consuming, expensive, and sometimes disruptive, especially as grids face harsh weather risks that complicate construction and operations. Residents and businesses might worry about potential rate increases required to fund these necessary investments.
Opportunity for Innovation
The IESO and the city view the situation as an opportunity to embrace innovative solutions. Exploring renewable energy sources within and near the city, developing local energy storage systems, and promoting distributed energy generation such as rooftop solar, where power is created near the point of use, are all vital strategies for meeting needs in a sustainable way.
Toronto's electricity future depends heavily on proactive planning and investment in modernizing its power infrastructure. The decisions made now will determine whether the city can support economic growth, address climate goals and a net-zero grid by 2050 ambition, and ensure that lights stay on for all Torontonians as the city continues to expand.
US Utilities Shift From Coal as natural gas stays cheap, renewables like wind and solar scale, Clean Power Plan uncertainty lingers, and investors, state policies, and emissions targets drive generation choices and accelerate retirements.
Key Points
A long-term shift by utilities from coal to cheap natural gas, expanding renewables, and lower-emission generation.
✅ Cheap natural gas undercuts coal on price and flexibility.
✅ Renewables costs falling; wind and solar add competitive capacity.
✅ State policies and investors sustain emissions reductions.
When President Donald Trump signed an executive order last week to sweep away Obama-era climate change regulations, he said it would end America's "war on coal", usher in a new era of energy production and put miners back to work.
But the biggest consumers of U.S. coal - power generating companies - remain unconvinced about efforts to replace Obama's power plant overhaul with a lighter-touch approach.
Reuters surveyed 32 utilities with operations in the 26 states that sued former President Barack Obama's administration to block its Clean Power Plan, the main target of Trump's executive order. The bulk of them have no plans to alter their multi-billion dollar, years-long shift away from coal, suggesting demand for the fuel will keep falling despite Trump's efforts.
The utilities gave many reasons, mainly economic: Natural gas - coal’s top competitor - is cheap and abundant; solar and wind power costs are falling; state environmental laws remain in place; and Trump's regulatory rollback may not survive legal challenges, as rushed pricing changes draw warnings from energy groups.
Meanwhile, big investors aligned with the global push to fight climate change – such as the Norwegian Sovereign Wealth Fund – have been pressuring U.S. utilities in which they own stakes to cut coal use.
"I’m not going to build new coal plants in today’s environment," said Ben Fowke, CEO of Xcel Energy, which operates in eight states and uses coal for about 36 percent of its electricity production. "And if I’m not going to build new ones, eventually there won’t be any."
Of the 32 utilities contacted by Reuters, 20 said Trump's order would have no impact on their investment plans; five said they were reviewing the implications of the order; six gave no response. Just one said it would prolong the life of some of its older coal-fired power units.
North Dakota's Basin Electric Power Cooperative was the sole utility to identify an immediate positive impact of Trump's order on the outlook for coal.
"We're in the situation where the executive order takes a lot of pressure off the decisions we had to make in the near term, such as whether to retrofit and retire older coal plants," said Dale Niezwaag, a spokesman for Basin Electric. "But Trump can be a one-termer, so the reprieve out there is short."
Trump's executive order triggered a review aimed at killing the Clean Power Plan and paving the way for the EPA's Affordable Clean Energy rule to replace it, though litigation is ongoing. The Obama-era law would have required states, by 2030, to collectively cut carbon emissions from existing power plants by 30 percent from 2005 levels. It was designed as a primary strategy in U.S. efforts to fight global climate change.
The U.S. coal industry, without increases in domestic demand, would need to rely on export markets for growth. Shipments of U.S. metallurgical coal, used in the production of steel, have recently shown up in China following a two-year hiatus - in part to offset banned shipments from North Korea and temporary delays from cyclone-hit Australian producers.
RETIRING AND RETROFITTING
Coal had been the primary fuel source for U.S. power plants for the last century, but its use has fallen more than a third since 2008 after advancements in drilling technology unlocked new reserves of natural gas.
Hundreds of aging coal-fired power plants have been retired or retrofitted. Huge coal mining companies like Peabody Energy Corp and Arch Coal fell into bankruptcy, and production last year hit its lowest point since 1978.
The slide appears likely to continue: U.S. power companies now expect to retire or convert more than 8,000 megawatts of coal-fired plants in 2017 after shutting almost 13,000 MW last year, according to U.S. Energy Information Administration and Thomson Reuters data.
Luke Popovich, a spokesman for the National Mining Association, acknowledged Trump's efforts would not return the coal industry to its "glory days," but offered some hope.
"There may not be immediate plans for utilities to bring on more coal, but the future is always uncertain in this market," he said.
Many of the companies in the Reuters survey said they had been focused on reducing carbon emissions for a decade or more while tracking 2017 utility trends that reinforce long-term planning, and were hesitant to change direction based on shifting political winds in Washington D.C.
"Utility planning typically takes place over much longer periods than presidential terms of office," Berkshire Hathaway Inc-owned Pacificorp spokesman Tom Gauntt said.
Several utilities also cited falling costs for wind and solar power, which are now often as cheap as coal or natural gas, thanks in part to government subsidies for renewable energy and recent FERC decisions affecting the grid.
In the meantime, activist investors have increased pressure on U.S. utilities to shun coal.
In the last year, Norway's sovereign wealth fund, the world's largest, has excluded more than a dozen U.S. power companies - including Xcel, American Electric Power Co Inc and NRG Energy Inc - from its investments because of their reliance on coal-fired power.
Another eight companies, including Southern Co and NorthWestern Corp, are "under observation" by the fund.
Wyoming-based coal miner Cloud Peak Energy said it doesn't blame utilities for being lukewarm to Trump's order.
"For eight years, if you were a utility running coal, you got the hell kicked out of you," said Richard Reavey, a spokesman for the company. "Are you going to turn around tomorrow and say, 'Let's buy lots of coal plants'? Pretty unlikely."
Gulf Power Hurricane Michael Response details rapid power restoration, grid rebuilding, and linemen support across the Florida Panhandle, Panama City, and coastal areas after catastrophic winds, rain, and storm surge damaged transmission lines and substations.
Key Points
Gulf Power's effort to restore electricity after Hurricane Michael, including grid rebuilding and storm recovery.
✅ 3,000+ crews deployed for restoration and rebuilding
✅ Transmission, distribution, and substations severely damaged
✅ Panhandle customers warned of multi-week outages
Less than 24 hours ago, Hurricane Micheal devastated the residents in the Florida Panhandle with its heavy winds, rainfall and storm surge, as reflected in impact numbers across the region.
Gulf Power crews worked quickly through the night to restore power to their customers.
Linemen crews were dispatched from numerous of cities all over the U. S., reflecting FPL's massive Irma response to help those impacted by Hurricane Michael.
According to Jeff Rogers, Gulf Power spokesperson; “This was an unprecedented storm, and our customers will see an unprecedented response from Gulf Power. The destruction we’ve seen so far to this community and our electrical system is devastating — we’re seeing damage across our system, including distribution lines, transmission lines and substations.”
Gulf Power told Channel 3 said they dealt with issues like trees and heavy debris blocking roads from strong winds, and communications down can slow down the rebuilding and restoration process, but Gulf Power said they are prepared for this type of storm devastation.
According to Gulf Power, Hurricane Micheal caused so much damage to Panama City's electrical grid that crews not only had repair the lines, they had to rebuild the electrical system, a scenario similar to a complete rebuild seen after Hurricane Laura in Louisiana.
Gulf Power officials say, "Less than 24 hours after the storm, more than 3,000 storm personnel from around the country arrived in the Panama City area Thursday to begin the restoration and rebuilding process. So far, more than 4,000 customers have been restored on Panama City Beach. Power has been restored to all customers in Escambia, Santa Rosa and Okaloosa counties, and it’s expected that customers in Walton County will be restored tonight. But customers in the hardest hit areas should prepare to be without power for weeks, not days in some areas. Initial evaluations by Gulf Power indicate widespread, heavy damage to the electrical system in the Panama City area."
According to Gulf Power, crews have restored power to more than 32,000 Gulf Power customers in the wake of Hurricane Michael, but the work is just beginning for power restoration in the Panama City area.
Rogers said, “We’re heartbroken for our customers and our teammates who live in and near the Panama City area,” said Rogers. “This is the type of storm that changes lives — so aside from restoring power to our customers quickly and safely, our focus in the coming days and weeks will also be to help restore hope to these communities and help give them a sense of normalcy as soon as possible.”
Calgary Winter Energy Usage Surge highlights soaring electricity demand, added megawatt-hours, and grid reliability challenges driven by extreme cold, heating loads, and climate change, with summer air conditioning also shifting seasonal peaks.
Key Points
A spike in Calgary's power use from extreme cold, adding 22k MWh and testing reliability as heating demand rises.
✅ +22,000 MWh vs Feb 2018 amid fourth-coldest February
✅ Heating loads spike; summer A/C now drives peak demand
✅ Grid reliability monitored; more solar and green resources ahead
February was so cold in Calgary that the city used enough extra energy to power 3,400 homes for a whole year, echoing record-breaking demand in B.C. in 2021 during severe cold.
Enmax Power Corporation, the primary electricity utility in the city, says the city 's energy consumption was up 22,000 megawatt hours last month compared with Februray 2018.
"We've seen through this cold period our system has held up very well. It's been very reliable," Enmax vice-president Andre van Dijk told the Calgary Eyeopener on Friday. "You know, in the absence of a windstorm combined with cold temperatures and that sort of thing, the system has actually held up pretty well."
The past month was the fourth coldest in Calgary's history, and similar conditions have pushed all-time high demand in B.C. in recent years across the West. The average temperature for last month was –18.1 C. The long-term average for February is –5.4 C.
Watching use, predicting issues
The electricity company monitors demand and load on a daily basis, always trying to predict issues before they happen, van Dijk said, and utilities have introduced winter payment plans to help customers manage bills during prolonged cold.
One of the issues they're watching is climate change, and how extreme temperatures and weather affect both the grid's reliability, as seen when Quebec shattered consumption records during cold snaps, and the public's energy use.
The colder it gets, the higher you turn up the heat. The hotter it is, the more you use air conditioning.
He also noted that using fuels then contributes to climate change, creating a cycle.
"We are seeing variations in temperature and we've seen large weather events across the continent, across the world, in fact, that impact electrical systems, whether that's flooding, as we've experienced here, or high winds, tornadoes," van Dijk said.
"Climate change and changing weather patterns have definitely had had an impact on us as an electrical industry."
In 2012, he said, Calgary switched from using the most power during winter to using the most during summer, in large part due to air conditioning, he said.
"Temperature is a strong influencer of energy consumption and of our demand," van Dijk said.
Christmas tree lights have also become primarily LED, van Dijk said, which cuts down on a big energy draw in the winter.
He said he expects more solar and other green resources will be added into the electrical system in the future to mitigate how much the increasingly levels of energy use impact climate change, and to help moderate electricity costs in Alberta over time.
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.”
