Implementing Interchange Interchange Transactions are the representation of a PSE or BA arranging for energy and capacity transfers between different parties. From a real-world perspective, these compiled arrangements are known as a Request for Interchange (RFI). The RFI goes through two types of assessment: Market Assessment and Reliability Assessment. Prior to the assessment stages, the PSE puts together the business arrangements for the Interchange with Transmission Service Providers (TSPs), Generators, and LSEs and may obtain preliminary reliability approvals from BAs, TSPs, and RCs where required. At this stage, Agreements (including Transmission reservations) are aggregated into a single request. This aggregated information is sent to the BAs, PSEs, and TSPs and begins both the Market Assessment and Reliability Assessment. During the Market Assessment and Reliability Assessment, the RFI proposed by the PSE is evaluated by the approval entities to ensure all the proper information has been for both commercial and reliability issues and that system conditions allow for approval. Note that the actual RFI submission can be assessed and approved or denied by both market and reliability entities. In both the NERC Standards and NAESB Business Practice Standards, RFIs go through several transitions as they are evaluated. Prior to either assessment period, any compiled arrangements are known only as RFI. Once the RFI is passed to the reliability and market entities to begin evaluation during the Reliability Assessment and Market Assessment, respectively, then the RFI becomes known as Arranged Interchange. If approvals are obtained from all entities with approval rights during the Reliability Assessment and Market Assessment, then the Arranged Interchange transitions to Confirmed Interchange. Confirmed Interchange has obtained all necessary approvals and is ready to be implemented in the Net Scheduled Interchange portion of all impacted BAs. Once the Ramp start time is reached, the Confirmed Interchange transitions to Implemented Interchange. At that point in time, each impacted BA will implement the Implemented Interchange value into their Area Control Error (ACE) equation as part of the Net Scheduled Interchange.
