Recovery of Capacity charge
The capacity charge shall be recovered in two
parts, viz., Capacity Charge for Peak Hours of the
month and Capacity Charge for Off- Peak Hours of
the month
The capacity charge recovered under two segments
of the year, i.e. High Demand Season (period of
three months) and Low Demand Season (period of
remaining nine months), and within each season in
two parts viz., Capacity Charge for Peak Hours of
the month and Capacity Charge for Off Peak Hours
of the month
High Demand and low Demand seasons
