This included operational case studies illustrating benefits and minor impacts of the voltage limit change, including improved outage scheduling and demand security. The Panel agreed that further refinement is required before the modification can return for approval. The Proposer will address the additional comments received and bring the revised Proposal to the next Panel meeting.
