Eni Executive Hot Fusion Reactor would Cost $3 Billion

The reactor would power around 150,000 homes; or a city about the size of Norwich, England. This estimate is based on the standard calculation that a megawatt is enough electricity for 750 homes.
A megawatt is one million watts of electricity, so the reactor would generate 200 million watts of electricity. That reactor would have the capacity to generate electricity as soon as it was up and running.

“After the transition to renewable energy, the real breakthrough technologically is nuclear fusion,” Robert Casula told Reuters. Casula thinks it would cost $3 billion to develop and build a 200-megawatt fusion reactor and it might be up and running by 2033.
