Proposed Protocol Language Revision

15.4.1.4New Electric Service Identifier Creation

(1)Since it is anticipated that the ESI ID will be based on the existing TDSP account or Premise numbers (with a prefix identifying the TDSP), the TDSP will assign and submit to the registration database ESI IDs for new Premises as service is extended to them. TDSPs that opt in after the market startup will be responsible for the creation of ESI IDs for all existing Service Delivery Points in their service territory.

(2)The TDSP will send ESI ID information using the 814_20, ESI ID Maintenance Request. ERCOT will verify that this transaction meets Texas Standard Electronic Transaction (TX SET) specifications. ERCOT will respond to the TDSP within one Retail Business Hour, with acceptance or rejection of these transactions using the 814_21, ESI ID Maintenance Response. At least the following data elements are required to be sent in the 814_20 transaction:

(a)ESI ID;

(b)Service Address; city, state, zip;

(c)Load Profile Type;

(d)Meter reading cycle or meter cycle by day of month;

(e)Station ID;

(f)Distribution Loss Factor (DLF) code; and

(g)Premise type.

(3)The TDSP must receive an accepted 814_21 from ERCOT prior to initiating electric service pursuant to Section 15.1.4, Beginning Service (New Construction Completed and Move Ins).
