Starting in June 2008, RTM scheduling will consider the DAM cleared status of a transaction before the timestamp of the submittal to the RTM. With this change, the timestamp is not as critical to the RTM scheduling process as it was before. Therefore, the ISO has eliminated the action of denying transactions that were submitted prior to noon the day-before the Operating Day that do not pass the day-before checkout process with the neighboring control area. This change is incorporated in OP 9, Scheduling and Dispatch of External Contracts.
The result of this change is that customers can submit transactions up to 10 days prior to the start of the transaction to be considered ONLY in the RTM. Customers no longer have to wait until after noon the day-before the Operating Day to submit transactions for consideration in ONLY the RTM.
In normal scheduling and curtailment, the general criteria were modified to incorporate the DAM cleared status of the transactions in the tiebreaking logic. Previously, the general criteria were: price, transmission priority, timestamp (or pro-rata). Now, the general criteria are: price, transmission priority, DAM cleared status, and then timestamp (or pro-rata). This is detailed in the ISO New England Open Access Transmission Tariff, Section II.44 – Scheduling and Curtailment Rules for Real-Time External Transactions.
After the ISO issues an M/LCC 2 Abnormal Conditions Alert, any Export transactions that were submitted only to the RTM are subject to reduction before other Export transactions that cleared the DAM. If Operating Procedure 4, Action During a Capacity Deficiency (OP 4) is declared, transactions that cleared the DAM will be reduced as defined within the ISO Manual for Market Operations, M-11, and OP 4 to mitigate the emergency condition.
Prior to reducing any Export transactions that have cleared the DAM, the ISO will attempt to schedule all priced Import transactions. To the extent that priced Import transactions supporting an ICAP Import Contract are not available to be scheduled, they may be assigned a "Failure to Deliver" penalty.
Each customer that has transactions in the RAA will get a non-binding report of how those transactions were scheduled by the most recent RAA, comparable to the report currently received by internal generation. The FI_RTDISPETIMPORT Market Information Server (MIS) report will be available on the ISO's FTP file server after each case of the RAA has been approved.
Historical bid data will begin to be published in June 2008 for external transactions with the same publishing schedule as internal generation. Historical Import and Export Bid data is located on the ISO Web under Markets > Historical Data > Historical Market Offer & Bid Data > Day-Ahead & Real-Time Import Offer & Export Bid Data.
