Mechanism:

Electronic data file transfer



Frequency:

Daily


Volumes:

Several hundred Metering Systems



Interface Requirement:

CDCA will forward meter period data for all Grid Supply Points Metering Systems, Interconnectors and Inter-GSP-Group Connections, to the relevant host distribution business(es), where required.
A report will be sent to the Distribution Business associated with each GSP Group which shall include the following data:

GSP Group Id

Settlement Date

Settlement Run Type

CDCA Run Number

Date of aggregation


GSP Id

Estimate Indicator (T/F)

Meter Volume

Import/Export indicator (I/E)
Interconnector Id

Settlement Period

Estimate Indicator (T/F)

Meter Volume

Import/Export indicator (I/E)
Inter-GSP-Group Connection Id

Settlement Period

Estimate Indicator (T/F)

Meter Volume

Import/Export indicator (I/E)

The file can be provided on request to a BSC Party which is active within the relevant GSP Group.


The Import/Export indicator indicates the direction of the energy flow: the Meter Volume is therefore unsigned.

5.27 CDCA-I037: (output) Estimated Data Notification


Interface ID:

CDCA-I037

The information provided is as follows:
BSC Party Identifier

Metering System Identifier

Settlement Date

Outstation Id

Channel Number

Meter Serial Number

Measurement Quantity (Active Import , Active Export)

Settlement Period (46, 48 or 50 occurrences)

Original Meter Reading Volume (if available)

Estimated Meter Reading Volume

Estimation Method
Estimation method is an indicator of the method used for estimation:

A - Generation: Main meter data missing or incorrect in Primary and Secondary Outstations, Check meter data available – copied from Primary Check

D - Demand: Main meter data missing or incorrect, Check meter data available – copied from Primary Check

E - Demand: Main meter data missing or incorrect, Check meter not fully functional, but Main meter or Check meter register advance available – profiled using Meter Reading Estimation Tool

I - Demand: Main meter data missing or incorrect, Check meter not fully functional, Main meter and Check meter register advance NOT available – profiled using Trend

K - Generation: Main and Check meter data missing or incorrect in Primary and Secondary Outstations, data estimated to zero awaiting confirmation of generation

M - Demand: Main meter data missing or incorrect, data copied from suitable settlement period(s)

N - Validation Failure: Main meter data deemed correct

U - Used parties own reading

X - Used different estimation method


If Estimation method = X, the method used will be described.
Method codes J and L (see CDCA-I014) refer specifically to substitution, rather than estimation, and are therefore not reported via this flow.
