The RTO/ISO responses clearly confirm that there is not a nationwide problem during the morning electric ramp associated with the current start time of the Gas Day.
Moreover, no RTO or ISO has shown a causal link between generator de-rate issues and the current 9:00 am CT start of the Gas Day. Given that the responses fail to provide sufficient record evidence for the Commission to meet its burden under section 5 of the Natural Gas Act that the current 9:00 am CT Gas Day start time is no longer just and reasonable, and that a 4:00 am CT start of the Gas Day is just and reasonable, the NGC renews its request that the Commission retain the 9:00 am CT Gas Day as the national standard.
