Note:
The underlined data show that the FOCA for July / August is
based on costs and billings for the month of May / June 2000.
The costs and billings of May will be known at the end of
June and will be thus recovered in FOCA for July.
The computation of FOCA for various consumer categories would
be done in the following manner:
The FOCA for metered / unmetered consumers in a month j would
be calculated as:
FOCAm,j = Am,j-2 / Xm,j-2 (Rs./kWh)
FOCAu,j = Au,j-2 / Yu,j-2 (Rs./HP/month)
4
In the last tariff order, Rs 10532 crore revenue is estimated
from metered consumers and Rs 878 crore revenue is estimated
from unmetered consumers.
Where, FOCAm,j = Fuel and Other Costs Adjustment charge for
all metered consumption (Rs./kWh) for the month j
FOCAu,j = Fuel and Other Costs Adjustment charge for all unmetered
consumption (Rs./HP/month) for the month j
Am,j-2 = Incremental cost to be recovered from metered consumptionThe
incremental cost to be recovered from metered consumption would
be calculated as (Aj-2 * Proportion of revenue from metered
consumption estimated in determination of tariffs).
Au,j-2 = Incremental cost to be recovered from unmetered consumptionThe
incremental cost to be recovered from unmetered consumption
would be calculated as (Aj-2 * Proportion of revenue from
unmetered consumption estimated in determination of tariffs).
Xm,j-2 = Number of units billed to metered consumers during
the month for which incremental cost has been computed (i.e.
month j-2)
Yu,j-2 = Number of HP (connected load) of unmetered consumers
during the month for which incremental cost has been computed
(i.e. month j-2)
The entire illustration of the formula for the period May to
December 2000, assuming that the proposed formula was applicable
from May, is provided in the table on the following page. |
