What should I do when a scheduled transaction gets derated?
The NYISO will derate a transaction i.e, reduce the MW amount of the transaction before it is evaluated by Balancing Market Evaluator (BME), to maintain the reliable operation of the New York control area. Quite often the NYISO will derate a transaction based on knowledge provided by a neighboring control area that even if the transaction is accepted in the NYISO Locational Based Marginal Pricing (LBMP) market, the transaction will not flow due to reasons external to New York. When a transaction is derated an automatically generated email is sent to the scheduler of the transaction specifying the New York Control Area (NYCA) identification number with the corresponding MW value, the time of the derate, and the reason for the derate. More detailed information about the real time interface conditions can be obtained by viewing the Operational Announcements link on the OASIS page under Operational Information. To reinstate the transaction, it is the responsibility of the market participan
