Network Charge Validation Error Messages

Network Charge Validation is set up with the EDI Setup Activity and are valid for EDI Bills only.

Note: These Validators only work on Bills which have start dates on or after 1st April 2022.k


In summary, the validation that can be performed:

  • LLF and ASC combination are valid (i.e. new TCR charging bands)
  • Unit Rate Validation: RAG (Red, Amber, Green) Charges, Standing Charge, Capacity Charge, Excess Capacity Charge and Reactive Power Charge
  • Consumption Validation: Checks that the HH Consumption has been apportioned into the appropriate Red, Amber and Green bands (where HH meters are linked to the Billing Account)
  • Consumption Losses Validation: Checks that the appropriate loss coefficients have been applied to the metered consumption


This Validation is done through the following Validators.  If Validation fails, the following error messages will appear:


DUOS Band Mapping Validation

Takes the Distribution area (from the MPAN on the bill) and checks that the DUOS bands match the expected bands.

Validator Message

Bill

       

This bill shows the charges as DUoS Unit Charges 1, 2 and 3.  Other bills may shows as Red, Amber and Green.

Explanation

Expected and actual DUO bands don't match -

an LLF of '093'  -  the last part of the top line of the MPAN  on the bill - 093

and an ASC of '900' - the Agreed Supply Capacity on the bill

for distributor '10' - the Distributor ID on the bill (first section of the bottom line of the MPAN)

should be charged using band 'HVSiteSpecificBand1' (0 kVA to 5000 kVA,  - the Band for LLF 093, with a capacity of 900, in the Distributor 10 area should be Band 1

however the bill was actually charged using band 'HVSiteSpecificBand3' (12000 kVA to 21500 kVA) -  The bill has charged DUOS charges at Band 3, a higher charge


DUOS Capacity Rate Validation

Takes the Distribution area (from the MPAN) and checks that the capacity rates applied to the relevant kVA results in the correct capacity charge

Validator Message

Bill


Explanation

Billed monthly rate '39.20 p/kVA'  -  the bill shows 0.392 (pence) Capacity Charge

does not match published calculated rate of '40.60 p/kVA'  - the current published rate for an MPAN / Distributor  


DUOS Consumption Rates Validation 

Takes the Distribution area (from the MPAN on the bill) and checks that the consumption billed for the red / amber / green time periods is correct (this can only happen where the billing accounts is also linked with the fiscal half-hourly meter via the Supply Point).

Validator Message

 

Bill

This bill shows the charges as DUoS Unit Charges 1, 2 and 3.  Other bills may shows as Red, Amber and Green.

Explanation

Billed charge 'red' with rate of '3.533 p/kWh' - the bill shows a rate of 3.533  (DUoS Unit Charge 1)

does not match published rate of '4.790 p kWh' - the current rate for red with an LLF in the 23 Distribution area is 4.790  (the bill is 0.03533)

Billed charge 'green' with rate of '0.990 p/kWh' - the bill shows a rate of 0.990 (DUoS Unit Charge 3)

does not match published rate of '0.99 p/kWh' - the current rate for green with an LLF in the 23 Distribution area is 0.99  (the bill is 0.990)

Billed charge 'amber' with rate of '1.405 p/kWh'  - the bill shows a rate of 1.405  (DUoS Unit Charge 2)

does not match published rate of '1.004 p/kWh' - the current rate for amber with an LLF in the 23 Distribution area is 1.004  (the bill is 1.405)


DUOS Excess Capacity Rate Validation

Takes the Distribution area (from the MPAN on the bill) and checks that the excess capacity rates applied to the relevant kVA result in the correct excess capacity charge.

Validator Message

Bill


Explanation

Billed month rate '8.30 p/kVA' - the bills shows 0.083

does not match published calculated rate of '249.00 p kVA' -  the current published rate for the MPAN / Distributor / LLF 


DUOS Reactive Power Rate Validation 

Takes the Distribution area (from the MPAN on the bill) and checks that the standing charge rate applied to the relevant KvarH results in the correct fixed charge.

Validator Message

Bill

Explanation

Billed rate of .0.388 p/kVarh' - the rate shown on the bill

does not match published rate of '0.0000 p/kVArh' - the published rate


DUOS Standing Charge Validation 

Takes the Distribution area (from the MPAN) and checks that the standing charge rate applied to the relevant number of bill days results in the correct fixed charge.

Validator Message

Bill

This bill shows the charges as DUoS Unit Charges 1, 2 and 3.  Other bills may shows as Red, Amber and Green.

Explanation

Billed month cost '5.57'  -  the bill shows 28  days x 19.91p = £5.57

does not match published calculated cost of '5.77'  - the published rate for Distributor


DUOS Timeband Consumption Validation 

Takes the Distribution area (from the MPAN on the bill) and checks that the total Red, Amber and Green charges are correct compared with rates published for the LLF / Distributor.

Validator Message

Bill


DUOS consumption for band red had a billed value of: 1217.90, -  the cost on the bill for DUOS red units

but the calculated value was: 6717.40 -  the published rate

DUOS consumption for band green had a billed value of: 5287.90, -  the cost on the bill for DUOS green units

but the calculated value was: 3876.40  - the published rate

DUOS consumption for band amber has a billed value of: 3010.10, -  the cost on the bill for DUOS amber units

but the calculated value was: 20305.80 - the published rate


Losses Calculation Validation 

This validation checks that the HH metered consumption uplifted by the published loss coefficients represents the consumption that has been billed against the consumption based distribution charges. The HH data must exist against a Periodic Channel in Sigma and be connected to the Account via the Supply Point.

Distribution Losses are the difference between the electricity entering the distribution network and that leaving it (i.e. going into a meter).
For example, 100kWh goes in, by the time it gets to the meter, that may be 90kWh which means that 10kWh has been lost on the network as it flows through the cables.
The Distribution charges are usually levied on the full 100kWh that enters the system. As such, the metered consumption (90 kWh) is multiplied by a loss factor to get it back to the full 100 kWh for the purpose of billing. These Loss factors (or loss coefficients) are publishes by the Distribution network operators.

Explanation

Billed GSP Consumption 59262.20 - the consumption on the bill

does not match loss adjusted consumption of 300833.80 - the consumption in the  Periodic Channel associated with the Account


MPAN Top Line Validation 

Checks the top line of the MPAN is a valid combination
