The AEMC has commenced consultation on a Rule change request from Hydro Tasmania in relation to the limit allowed for temporary power frequency voltages at a connection point. Hydro Tasmania proposes that the limits on temporary over-voltages should be disassociated from the level of the normal voltage to allow for an increase in limits.

On 30 June 2011, the AEMC published Hydro Tasmania’s Rule change request and an AEMC staff Consultation Paper regarding the request. Submissions close on 12 August 2011.
