PAF-: The Average of the Daily Declared Capacities for all the Days during that period expressed as a percentage of the Installed Capacity in MW reduced by the Normative Auxiliary Consumption.
PAFM/PAFY=10000* DC/(N*IC*(100-AUX) )% NAPAF ( Normative Annual Plant Availability Factor) for thermal around 85%
NAPAF ( Normative Annual Plant Availability Factor) for hydro around 85-90%

Weighted Average of Percentage Allocation Capacity Decides the Ratio in Which Fixed Capacity Charges
is to be share by Beneficiaries. It takes care of URS power also ( in line with CERC
Order dated 11/01/10 on petition No. 134/2009 of NTPC)

Additional UI Frequency is less than 49.5 Hz and up to 49.2 Hz
Over Drawal = 40% of UI Rate 873 paise/kwh Under injection by seller = 20% of UI Rate 873
paise/kwh Under injection by GS = 20% of UI Rate 403 paise/kwh
Frequency is less than 49.2 Hz Over Drawal = 100% of UI Rate 873 paise/kwh Under injection by seller = 40% of UI Rate 873

VAR charges between two beneficiaries on interconnecting line owned by them singly or jointly
Can agree mutually not to have any charges. Can mutually agree to adopt any payment rate / scheme.
Or can adopt rate specified by CERC. In case of disagreement, they have to adopt scheme
specified by CERC in Annexure -3 (given below)
Payment to be made if one is to pay and other is to receive and will be min(x1,x3)+min(x2,x4). IN SR it is min(x1+x2,x3+x4)
Payment will be between the two beneficiaries on one to one basis
