About NMI discovery

To learn more about NMI Discovery, see Technical Guide to MSATS.upa

From the NMI Discovery menu, you can:

• Discover a customer’s NMI See Relevant Rules or Procedures and checksum if it is not known such as, when the customer cannot provide it (search type 1).
• Discover sufficient Standing Data about the NMI to provide a customer with a quotation (search type 2).
• Identify the current or most recent previous Retailer See Relevant Rules or Procedures for a NMI (search type 3).
• Find a Meter's Previous Read Date and Quality Flag.

Search Type 1: NMI Discovery

NMI Discovery Search Key Rules may prevent access to certain search criteria, see Jurisdictional rules.

All Participant Users with appropriate access rights can use the NMI Discovery search type 1 provided their Participant ID Registered participant identifier; A company can have more than one Participant ID. is registered in MSATS Market Settlement and Transfer Solutions. The procedures published by AEMO under clause 7.2.8 of the National Electricity Rules, which include those governing the recording of financial responsibility for energy flows at a connection point, the transfer of that responsibility between market participants, and the recording of energy flows at a connection point. as acting in a Role The role a company has with a connection point in CATS. A single company can have more than one role associated with a NMI. allowed access to NMI Discovery.

The Participant User A Participant ID's users created and maintained by the Markets Portal PA in the URM. undertaking the search does not need to hold an existing participant Role Relationship against the NMI for Standing Data to be returned unless their Role is LNSP. LNSPs can only search their own NMIs.

Search Type 2: Obtain Standing data

Search Type 2 is the process of entering a NMI and checksum to locate Standing Data about the NMI.

When the NMI and checksum are known, a Standing Data search returns the data to assist Retailers to provide a quote to an End-use Customer and find Meter Read data information for the customer switching process.

Detailed information is returned regarding the NMI, based on the NMI Discovery Field Access Rules The National Gas or Electricity rules.. Information included is the Network Tariff Code A nominated code for the Network Tariff charged by the NSP., TNI code, DLF Distribution Loss Factor. The loss of energy, due to electrical resistance and the heating of conductors, as electricity flows through the transmission and distribution networks. code and information about the Metering configuration. These rules are governed by the NMI's Jurisdiction participating jurisdiction (defined in the NER).

Search Type 3: Obtain Role Data

Search Type 3 assists in the identification of the Current The participant can receive files compliant to the current aseXML version. or most recent previous Retailer for a NMI and allows Retailers to provide a reason for their request.

NMI Discovery user rights access

Participant Administrators control access to NMI Discovery using the NMI Discovery entity in the Administration menu in the MSATS Web Portal.

Jurisdictional rules

The type of information, search criteria and number of results returned from the NMI Discovery or Standing Data search is governed by the NMI Discovery Search Key Rules and the NMI Discovery Field Access Rules, both of which are defined by each participating jurisdiction. If the number of corresponding records is greater than the number of records the user is permitted to view, only the number of items within the limit are returned. To reduce the number of records returned, refine the search criteria.

Participant Users may have access to view the Jurisdictional rules, using the Administration menu. for help, see Administration.

If no NMI Discovery Search Key Rules or NMI Discovery Field Access Rules are defined for a jurisdiction, then it means that the jurisdiction has not allowed NMI Discovery for any NMIs in that jurisdiction.

There is also a further jurisdictional rule that determines whether, in the event of multiple matches, the address of each matching NMI is also returned. The rule is set to yes for all jurisdictions allowing NMI Discovery.

Using search type 1 (NMI Discovery)

The search type 1 (NMI Discovery) is used to discover the following NMI information when a limited amount of NMI Standing Data See National Electricitiy Rules is known:

• NMI identifier
• NMI checksum
• NMI Address The address where the connection point the NMI refers to is located (the site address). During a consumer transfer, this information is supplied to the new retailer by the LNSP and acts as a check for the correct NMI identification. Details
• LNSP

To use search type 1 (NMI Discovery):

1. On the main menu, click NMI information and then click NMI Discovery.

Using search type 3 (obtain role data)

NMI Discovery search type 3 - obtain Role data assists in the identification of the current or most recent previous Retailer for a NMI and allows Retailers to provide a reason for their request.

Some search rules are:

• Correct Retailer: The Retailer that should be listed as the FRMP Financially Responsible Market Participant, usually a retailer, Generator, Market Customer or a Market Small Generator Aggregator, identified in respect of a connection point. Responsible for dealings with AEMO in relation to a specific load. for the NMI in MSATS. They are the end-use consumer’s chosen Retailer.
• Current Retailer See current FRMP or current FRMP: The Retailer who is currently listed with an active Role of FRMP for a NMI in MSATS.

• Most recent previous Retailer: The Retailer who was the FRMP before the NMI was transferred to the party listed as the current FRMP in MSATS.

To use search type 3 (Obtain Role Data):

1. On the NMI Information menu, click the NMI Discovery submenu.
2. Select Search Type 3 (Obtain Role Data) and complete the mandatory Reason, NMI, and Checksum fields, and then click Search.

Detailed NMI information is provided to Participant Users when there are single or multiple matches returned on a NMI Discovery search. In addition to providing the NMI and the NMI checksum, MSATS returns the following address fields from the CATS Customer Administration and Transfer Solution. A set of procedures, principles and obligations made under the National Electricity Rules as part of Market Settlement and Transfer Solutions (MSATS), and applicable to NMI (National Metering Identifier) small and large classifications._NMI_DATA table, provided the jurisdiction has authorised the return of the address details:
