3000MW for Mumbai。
India will be doing wonders if its 132 exaFlop supercomputer can achieve 20Gflops per watt。
Now work out the rest of the math for yoursself dude。
Here is a clue:you need 6 AP1000 nuclear power plants to generate enough electricity for your fancy132 exaflop super super computer。
So you are saying Indian Supercomp will use 6500 MWs Is it clear? (because its slightly higher than 3000 as you said)
