What is a high level description of the changes made to External Transactions in June?
The fundamental change that has taken place in June is that External Transactions that have cleared in the Day-Ahead Market (DAM) will have priority in the Real-Time Market (RTM) scheduling. This ensures that all transactions that have an obligation in the DAM will be scheduled before any transactions that are submitted to only the RTM. In addition, those transactions that are submitted to only the RTM may not be scheduled in Real-Time if the scheduling of those transactions will result in or worsen an emergency condition on the system.
