7.5 ECVAA-I005: (input) MVRN


Interface ID:

ECVAA-I005



Source:

MVRNA


Title:

Meter Volume Reallocation (MVR) Notifications



BSC reference:

ECVAA SD: 9.1, A

RETA ERR 2

ECVAA BPM: 3.3, 4.19

RETA SCH: 4, B, 3.4

CR 005, CR 008, CP527, P98



Mechanism:

Electronic Data File Transfer



Frequency:

Continuous



Volumes:

High


The ECVAA Service shall receive MVRNs from MVRNAs continuously for every Settlement Period up until Gate Closure.
The MVRNs shall comprise:


Meter Volume Reallocation Notification:

MVRNA ID


MVRNAA ID

MVRNAA Key

MVRN MVRNAA ID

MVRN Reference Code

Effective From Date

Effective To Date (optional)

Settlement Period (1-50)

Metered Volume Fixed Reallocation (MWh)

Metered Volume Percentage Reallocation (%)

Omitted Data: No Change (optional)10




Physical Interface Issues:
The MVRNA Id is the From Participant Id in the AAA header record of the physical file and so is not included in the MVN record.

The MVRN MVRNAA Id should always be either



  1. the MVRNAA Id of the Agent submitting the new/overwrite MVRN (If an MVRN already exists with the same reference code, the new MVRNs will be processed as amendments, i.e. being an overwrite rather than being additive), or

  2. an MVRNAA Id that has now expired (i.e. to date < todays date) but was for the same Lead and Subsidiary Party Energy Account;

An MVRN that does not follow these rules should be rejected in full.








See section 7.24 for more details; the information given there on ECVNs is equally applicable to MVRNs.
