Urgent: No
Sections: 15.2
Description: This Nodal Protocol Revision Request (NPRR) provides for the addition of Electric Service Identifier (ESI ID) attribute information for conditions in which the transaction type of 814_20, ESI ID Maintenance Request, is submitted that creates an ESI ID or makes changes to an existing ESI ID’s Advanced Metering System (AMS) or switch hold indicator flags utilizing the create or maintain option when submitting the 814_20 transaction.
Reason: This information will be provided at least daily to the Market Information System (MIS) Public Area and will provide Market Participants with visibility to new ESI IDs created in the market and any changes to a current ESI ID’s AMS or switch hold indicator. These defined triggers will provide the ESI ID attribute data similar to that in the Transmission and/or Distribution Provider (TDSP) ESI ID Extract on a more frequent basis. The current extract is provided on a weekly and monthly basis which contains a large data set and is resource intensive to produce and download.
