Injected power of 1-2 MW in the initial phase of operation with possible future upgrades up to 10 MW is planned for the electron cyclotron heating system. The injection of 140 GHz waves is considered for the fundamental harmonic heating of O-mode and the second and the third harmonic X-mode from the low-field side equatorial port. Preliminary evaluations of EC wave propagation and absorption, obtained from simulations with the beam-tracing code TORBEAM, are shown. Simulations from the beam-tracing proves the feasibility of the ECRH heating in lower magnetic field scenarios. Basic parameters of considered technical solution of gyrotrons, transmission line and launcher is described.
