Energy Accounting and Need for Special Energy Meters under ABT Regime

Energy Account The energy accounting closely monitors the energy flow within and beyond the organisation, and also to help identify areas where system efficiencies can be improved. It provides reports on the energy losses at each level of the transmission and distribution network, and within specific geographical regions. It also helps identify long- and short-term strategic management trends. To be FAIR and EQUITABLE To RECOVER DUES at the EARLIEST (Billing Cycle) TRANSPERANCY Dispute Resolution Reconciliation

Capacity charge: Capacity charge is based on Annual Fixed Charge and will be related to availability of generating station. Availability means the readiness of the generating station to deliver ex-bus output expressed as a percentage of its rated ex-bus output capability. Energy charge: Energy charge is related to the scheduled ex-bus energy to be sent out from the generating station and will be worked out on the basis of paise per KWh.

AVAILABILITY TARIFF(ABT) (a)CAPACITY CHARGE (b)ENERGY CHARGE (c)ADJUSTMENT FOR DEVIATIONS (UI CHARGE) (a)= a function of Ex-bus MW availability of power plant for the day declared before the day starts x SEB’s % share. (b)= MWh for the day as per ex=bus drawl schedule for the SEB finalized before the day starts x Energy charge rate (c)=Σ(Actual energy interchange in a 15 min time block – scheduled energy interchange for the time block) x UI rate for the time block. TOTAL PAYMENT FOR THE DAY = (a) + (b)± ( c)

SETTLEMENT SYSTEM For the day: 0000 hrs. to 2400 hrs.

SRLDC/Comml/IEGC/38

SETTLEMENT SYSTEM Actual (metered) injection of CGS-1 in the time block = X 1 MWh. Excess injection = (X1 – x 1 ’ ) MWh. 4 Amount payable to CGS-1 for this =(X1-x1’) * pool price for the block. 4 SEB-A’s scheduled drawl for time block = a 1 ’+a 2 ’+a 3 ’ = a’ MW (ex-CGS Bus) SEB-A’s NET drawal schedule = (a’ – Notional Transm. Loss) MW = (a’ – Notional Transm. Loss) = A’ MWH 4 Actual (metered) net drawal of SEB-A during time block = A MWH Excess drawal by SEB-A = (A-A’) MWh. Amount payable by SEB-A for this = (A-A’) * pool price for the block. All above payments for deviations from schedules to be routed through a pool A/C operated by RLDC SRLDC/Comml/IEGC/39

AVAILABILITY Availability in relation to a generating station for any period means the average of the DCs for all the days during that period expressed as a percentage of the installed capacity of generating station minus normative auxiliary consumption in MW and shall be computed as per the following formula:

Present Definition Capacity charges % Availability = i=1 N DC i / {NxICx(100-Aux n ) }% Where DC i = Average Declared Capacity for i th day of the period in MW N = Total no. of days during the period Aux n = Normative Auxiliary Consumption as % of gross Gen. IC= installed capacity in MW % Availability forms the basis for calculations i=1 N SG i / {NxICx(100-Aux n ) }% PLF =

Monthly Capacity charges receivable by an ISGS: 1 st Month = (1xACC1)12 2 nd Month = (2xACC2-1ACC1)12 …. …. 12 th month = (12xACC12-11ACC11)12 where ACC1,ACC2…….ACC12 = Annual capacity charges corresponding to the cum. Availability up to the corresponding month. Monthly Capacity charges payable by a beneficiary : 1 st Month = (1xACC1xWB1)12 2 nd Month = (2xACC2xWB2-1ACC1xWB1)12 …. …. 12 th month = (12xACC12xWB12-11xACC11xWB11)12 where WB1,WB2…..WB12 = Weighted average % share up to the corresponding month.

Variations in actual generation/drawal and scheduled generation /drawal are accounted through UI. This is a frequency linked charge which is worked out for each 15 minute time block. Charges for all UI transaction, based on average frequency have following rate of paise per KWh from up to UI rate (Paise per KWh) Average Frequency of time block 50.5 Hz. and above 0.0 Below 50.5 Hz. and upto Hz.5.6 Below Hz. and upto Hz Below Hz Between 50.5 Hz. and Hz.
