"The Joint European Torus at Culham,
England, to begin operations in 1983 - has been designed to produce more than 30 million
watts. In terms of the need for practical power generation, this is far from enough. (By
comparison, a typical modern nuclear fission plant produces something like a billion watts of
power, in other words, enough power to light, say, 10 million 100-watt lightbulbs while the plant
Bill Broad / New York Times — July 28, 1992
"Late last year, scientists at the Joint European Torus, an experimental fusion reactor in Oxfordshire, England, produced a significant amount of power from controlled fusion for the first time. The research team calculated that its reactor had yielded 1.5 million to 2 million watts in a pulse lasting two seconds. That success came after nearly half a century of worldwide effort and the expenditure of many billions of dollars. ITER would be the first machine in the world to go beyond short bursts of controlled fusion to operate continuously. Scientists hope that it would pave the way for practical reactors
producing a new kind of nuclear energy -- safe, cheap and nearly limitless."
Malcolm Brown /New York Times — Dec. 10, 1996
"If successful, the reactor would ignite a fusion reaction and produce up to 1.5 billion watts of power, demonstrating the feasibility of exploiting hydrogen fusion for large-scale power generation."
ITER was originally designed for a target of 1,500 MW gross thermal output.

"The goal of fusion research is a reactor that produces much more energy than the large amounts needed to run it. The experimental tokamaks that exist around the world, such as the Joint European Torus (JET) reactor at Culham near Oxford, have to date not progressed far beyond the break-even point."
Robert Stern / New York Times — Jan. 31, 2003
"ITER would provide a record 500 megawatts of fusion power for at least 500 seconds, a little more than eight minutes, during each experiment. That would meet the power needs of about 140,000 homes."
Elizabeth Clements / Fermi News — May 9, 2003
"If successful, ITER would produce 500 megawatts of fusion power for 500 seconds or longer ... the Tokamak Fusion Test Reactor at the Princeton Plasma Physics Laboratory, one of ITER’s predecessors that shut down in 1997, produced a maximum of 11 megawatts for only one-third of a second ... ITER would be the first magnetic confinement fusion experiment to produce burning plasma. The reaction would produce ten times the amount of external power injected into it."

"If it works, ITER will take in 50 megawatts of power and put out between 500 and 1,000 MW. That's right - it could power itself. ...

Daniel Clery / Science — Oct. 13, 2006
"The Joint European Torus (JET) in Abingdon, U.K., the biggest existing tokamak, managed to produce 16 megawatts, but that was only 65% of the power used to keep the reaction running. ... ITER aims to produce 500 megawatts of power, 10 times the amount needed to keep it running. German physicist Norbert Holtkamp says that ITER's goal of generating excess power is clear: 'Either it can do it, or it can't. If it fails, the tokamak is out.' ... Although there may be surprises along the way and whole new scenarios may have to be developed, few doubt that ITER will reach its goal of generating large amounts of excess power. But power is not much use commercially in bursts a few minutes long followed by a long wait while the reactor is reconfigured."

"Construction of the 500-megawatt reactor is expected to cost $6 billion and take a decade. Another $6 billion will be needed to operate it for 20 years. Even then the reactor will not be used to generate power. For safety reasons, the excess thermal energy produced will be released through cooling towers rather than harnessed to make electricity."
Geoff Brumfiel / Nature — Nov. 21, 2006
"ITER is a giant, €5 billion (US$6 billion) machine designed to prove that fusion power can work. It will use magnetic fields to confine hydrogen isotopes and heat them to hundreds of millions of degrees Celcius. If all goes well, the isotopes will fuse together — producing some 500 megawatts of power in the process."
The Economist — Nov. 23, 2006
"But getting more useful energy out of a machine than you put in has eluded the wit of man for 50 years—and a new move to throw more money at the problem marks political, not scientific, progress. ...
Construction of the 500-megawatt reactor is expected to cost $6 billion and take a decade. Another $6 billion will be needed to operate it for 20 years. Even then the reactor will not be used to generate power. For safety reasons, the excess thermal energy produced will be released through cooling towers rather than harnessed to make electricity. So a commercial reactor is at least 30 years away, as remote a prospect as fusion wonks said it was 50 years ago. And the problem it aims to solve—safely producing power with renewable resources—is being tackled more cheaply in other ways."

"ITER: A Brief History of Fusion"
"In JET, TFTR, and JT-60, scientists have approached the long-sought 'break-even point,' where a device releases as much energy as is required to produce fusion. ITER's objective is to go much further and release 10 times as much energy as it will use to initiate the fusion reaction. For 50 MW of input power, ITER will generate 500 MW of output power."

"The aim is for ITER to generate 500 megawatts of fusion power. This would pave the way for a demonstration power plant, called DEMO, in which fusion power will produce steam and – by way of turbines – up to 1000 megawatts of net electrical power.

"JET marked a key step in international collaboration, and in 1991 achieved the world’s first controlled release of fusion power. While a significant amount of fusion power was produced by JET, and TFTR, exceptionally long-duration fusion was achieved in the Tore Supra tokamak, a EURATOM-CEA installation located at France’s Cadarache nuclear research centre and later in the TRIAM-1M tokamak in Japan and other fusion machines."
"In JET, TFTR and JT-60 scientists have approached the long-sought 'break-even point,' where a device releases as much energy as is required to produce fusion. ITER’s objective is to go much further and release 10 times as much energy as it will use to initiate the fusion reaction."
"For 50 MW of input power, ITER will generate 500 MW of output power. ITER will pave the way for the Demonstration power plant, or DEMO, in the 2030s. As research continues in other fusion installations worldwide, DEMO will put fusion power into the grid by the middle of this century. The last quarter of this century will see the dawn of the Age of Fusion."
Charles Seife / Sun in a Bottle — Oct. 27, 2009
"JET got 6 watts out for every 10 it put in. It was a record, and a remarkable achievement, but a net loss of 40 percent of energy is not the hallmark of a great power plant."

"ITER is a large-scale scientific experiment that aims to demonstrate that it is possible to produce commercial energy from fusion. The ratio of fusion power (Q) to input power can be represented thus: Q = 10. The scientific goal of the ITER project is to deliver 10 times the power it consumes. From 50 MW of input power, the ITER machine is designed to produce 500 MW of fusion power - the first of all fusion experiments to produce net energy."

"Cowley is referring to the moment of parity when the amount of energy they extract from a tokamak equals the amount of energy they put into it. At present, the best-ever "shot" – as the scientists refer to each fusion reaction attempt – came in 1997 when, for just two seconds, the JET (Joint European Torus) tokamak at Culham achieved 16MW of fusion power from an input of 25MW."

"But, it takes more energy than it produces - JET produced 16 megawatts (MW) of power output, but required 24 MW of power input. Energy gain will be the goal of the International Thermonuclear Experimental Reactor (ITER) that will be built in Cadarache, France in the next few years. "It will have a net energy gain of 10, requiring a 50 MW input for a 500 MW output, which is approaching the levels we will need for commercial power stations," said Romanelli.

chordinine: "I was under the impression that a fusion reaction producing more energy than was put in was still a long ways away, and that a 1:1 ratio had not even been accomplished. Under this plan, they are saying that they can achieve a 1:10 energy ratio. Am I missing something?"
Powerfury: "They said it was a 1:10 ratio, but only for 300 second (5 minutes). So it does not seem sustainable for extended periods of time. This plant sounds more of a research plant for future progress."
nhillson: "ITER, in contrast, uses magnetic confinement fusion, which has produced at least a 70% return on input energy, and possibly a 125% return. It's now just a matter of scaling up, which increases the power produced, as well as the efficiency."
Neoshade: "It's not an advertisement. Billions of dollars have already been spent. Construction is underway in each country.
And yes, profitability is a long way off. ITER is meant to prove that net gain fusion can be done. They intend to produce energy for a matter of seconds, and to use this machine as a proof of concept and to learn more about how to do it right next time. Many smaller machines have been built to study fusion. This will be the largest ever and the first to achieve a net gain in energy."

RobusEtCeleritas: "ITER is not intended to be used for commercial power. It’s for fusion research, and proving that we can in fact reach ignition using magnetic confinement fusion reactors."
danherczak: "Thank you for your answer. What will they do with the energy it produces? Are they not even going to capture it?"
restricteddata: "The heat energy is just 'waste' if you don't do anything with it. They have a cooling system that works like most other cooling systems (cycles water through so that the heat can be removed and sent to cooling towers), albeit tuned to the expected needs of ITER."
Soloandthewookiee: "I would bet that the 500MW number is power-thermal, i.e., the heat generated from the reactor, not the electricity generated. I don't know that they would bother capturing it since that would require an entire steam cycle with turbines and generators. More likely, they'll use heat exchangers and reject the heat to the atmosphere or in some other manner. Also realize that it's an experimental reactor and is only intended to run for about 15 minutes at a time, so there's not much energy to be gained there.
To answer your original question, though, assuming the reactor generates 500MW-thermal and it has an efficiency of 33% (similar to fission reactors), subtracting the 50MW needed to sustain the reaction, it would generate around 150MW-electrical. The average US home uses about 1.2kW of electricity, so 150MW would be enough to power 125,000 homes."

TIMELINE NOTE: On Oct. 6, 2017, New Energy Times published "The ITER Power Amplification Myth," which led to many corrections and retractions of ITER power claims. Some of Bernard Bigot's subsequent public communications such as this one , this one, and this one, avoided the claim that the reactor would require only 50 MW of input power. Other organizations continued publishing the 50 MW input power claim without realizing that it was wrong.

"That might change in 2025, when the world’s biggest fusion project, ITER in France, is due to switch on. The hope is it will turn 50 megawatts of power into 500MW, proving a net gain is possible."
Daniel Clery / Science — Dec. 2, 2020
"The ITER tokamak in France, due for completion in 2025, will be the first to demonstrate energy gain, although that won’t happen until after 2035 and even then, the fusion energy won’t be used to generate electricity."
Peter Ray Allison / BBC — Dec.
"[ITER] will be a fully-working demonstration fusion reactor, providing 500 megawatts of fusion power – enough, if converted to electricity, to power a city the size of Liverpool."

Construction of the 500 MW ITER Tokamak is 72% complete, according to ITER's website.
The world record for fusion power is held by the European tokamak JET, which in 1997 produced 16 MW of fusion power from a total input heating power of 24 MW.
The in-construction ITER Tokamak is designed to produce a 10-fold return on energy, or 500 MW of fusion power from 50 MW of input heating power.
The project will not capture the energy it produces as electricity, but prepares the way for a machine that can, ITER said.

"It is this fuel mix that ITER will use in its attempt to create more power from a fusion
reaction than is put in — something that has
never before been demonstrated. ... The [JET] facility succeeded in achieving a record ratio of power out to power in (known as a Q value) of 0.67. That record still stands today; 1 would be break-even."
Caroline Delbert / Popular Mechanics — Feb. 22, 2021
In fact, the world’s existing fusion reaction record, a 0.67:1 ratio of fusion output to input, was set at JET using tritium in 1997. (For a fusion reactor to make power, it must reach a ratio of 1.01:1"

"The goal of ITER is to operate at 500 MW (for at least 400 seconds continuously) with 50 MW of plasma heating power input. It appears that an additional 300 MWe of electricity input may be required in operation. No electricity will be generated at ITER."
Matthew Sparkes / New Scientist — June 15, 2021
"The plan is to create 500 megawatts of usable energy from an input of 50 megawatts."
