[Clause 65 (1)]
Allocation of Annual Transmission Charges
1. The Long-Term and Medium-Term Users of the transmission system shall share the transmission cost in such proportion as their contracted transmission capacity to the total transmission capacity contracted/agreed from the intra-State transmission system.
The charges shall be calculated on a daily basis by the Transmission Licensee and shall be billed every month, except where directed otherwise by the Commission for any User or class of such users:
2) The Annual Transmission Charges (ATC) payable by a Long-term and Medium-Term User of the transmission system shall be computed in accordance with the following equation:
ATC = TC X [CL / SCL]
Where,
TC = Transmission Cost equivalent to the ARR of RVPN less income from short term open access transactions;
CL = Contracted/agreed Transmission Capacity of the User;
SCL = Sum of Contracted/agreed Transmission Capacity of all Users.
[Clause 66]
The charges shall be calculated on a daily basis by the Transmission Licensee and shall be billed every month, except where directed otherwise by the Commission for any User or class of such users:
2) The Annual Transmission Charges (ATC) payable by a Long-term and Medium-Term User of the transmission system shall be computed in accordance with the following equation:
ATC = TC X [CL / SCL]
Where,
TC = Transmission Cost equivalent to the ARR of RVPN less income from short term open access transactions;
CL = Contracted/agreed Transmission Capacity of the User;
SCL = Sum of Contracted/agreed Transmission Capacity of all Users.
[Clause 66]
Treatment of losses
Transmission Losses allowed by the Commission will have to be borne by users of the transmission system and energy accounts, to be maintained by SLDC, shall reflect
accordingly.
accordingly.
Incentive
Incentive = Annual Transmission Charges x [Annual availability achieved - Normative Availability] / Normative Availability;
No incentive shall be payable above the availability of 99.75%
Incentive to be paid to the Transmission Licensee shall be shared by the Licensees, long-term and medium-term open access customers.
[Clause 68]
No incentive shall be payable above the availability of 99.75%
Incentive to be paid to the Transmission Licensee shall be shared by the Licensees, long-term and medium-term open access customers.
[Clause 68]
Reactive Energy Charges
The Distribution Licensee shall provide the adequate capacitor bank at the load side and beyond the point of interconnection with the transmission system, wherever required, based on the system study carried out by the transmission Licensee and maintain the lagging power factor of not less than 0.95. The reactive energy charges for low power factor shall be specified by the Commission while specifying the Tariff Order from time to time
