You will have received a letter on the 13th April and Webinar on the 26^th April jointly from Electricity Settlements Company EMR Settlements Limited and the Delivery Body, which explained the Mock System Stress Event and timeline that will be undertaken this month (see latest news on EMR portal). The purpose of this email is to inform you of the settlement period selected for the exercise and explain the data submissions required from you, in order to test the Stress Event systems and processes.

- DSR CMU's are required to provide extra data (6weeks of data) to determine the baseline demand (as per schedule 2 of the CM rules).
