In case it is observed by RLDCs that the LTA or MTOA customer’s request for scheduling is consistently (for more than 5 days) lower than the quantum of LTA or MTOA granted by the Nodal Agency (i.e.; CTU), RLDC may issue a notice to such LTA or MTOA customer asking the reasons for such under-utilization. The un-utilized transfer capability will then be released for scheduling of Medium term and Short-term open access transaction depending upon the period of such underutilization.
