Progress in the definition of the requirements for ELM control and the application of ELM control methods both for high fusion performance DT operation and non-active low current operation in ITER is described. Uncontrolled ELMs for low plasma current H-modes are not likely to lead to damage to the W divertor target. Despite this, some level of ELM control is expected to be required in ITER to prevent an excessive contamination of the plasma by W which could eventually lead to an increased disruptivity. The evaluation of the capabilities of the ELM control coil system in ITER for ELM suppression (in the vacuum approximation) is presented as well as the consequences for the spatial distribution of the power fluxes at the divertor. The feasibility of the use of the in-vessel vertical stability coils for ELM control in low plasma current H-modes in ITER is described.
