Therefore, Real-Time Market (RTM) True-Up Statements for March 23, 2015 have been delayed due to insufficient IDR Meter data as per Protocol Section 9.5.8 - RTM True-Up Statement. True-Up Statements for this date scheduled to be posted on September 21, 2015 are expected to be posted on September 22, 2015.
