The generation of the magnetic field during a [[TJ-II]] discharge requires a total amount of power of almost 50 MW.
This power is supplied by the national grid and a 140 MW flywheel generator (100 MJ, 15 kV, 100 Hz).
As the TJ-II loads require a direct current, a set of thyristor converters, transformers and circuit breakers are used for each coil system.
The power requirements range from 5 kA (100 V) to 32 kA (1000 V).
The heating systems ([[TJ-II:Electron Cyclotron Resonant Heating|ECRH]] and [[TJ-II:Neutral Beam Injection|NBI]]) load the power supply with additional 15 MW.
