Payment of Transmission Charges
The transmission charges for access to and use of the intra-State transmission system shall comprise any of the following components or a combination of the following components:

(b) Annual transmission charges
(c) per unit charges for energy transmitted
(d)Reactive energy charges
[Clause 57.1]
(a) Transmission system access charges
(b) Annual transmission charges
(c) per unit charges for energy transmitted
(d)Reactive energy charges
[Clause 57.1]
Allocation of Annual Transmission Charges
1. The long-term Transmission System Users shall share the Total Transmission System Cost(TTSC) of the intra-State transmission system in the proportion of Base Transmission Capacity Rights of each Transmission System User to the total Base Transmission Capacity Rights allotted in the intra-State transmission system.
2. The Annual Transmission Charge payable by Transmission System User shall be computed in accordance with the following formula:
2.1. ATC(u)(t) = TTSC(t) X ([Base TCR(u)](t) / Σ u=1 to n [Base TCR(u)](t))
Where,
ATC(u)(t) = Annual Transmission Charges to be shared by Transmission System User (u) for the yearly period (t)
Base TCR (u) = [CPD(u)(t) + NCPD(u)(t)] /2
Where,
Base TCR represents the Base Transmission Capacity Right of each Transmission System User (u) for the yearly period (t)
CPD (u)(t) = Average Coincident Peak Demand of the Transmission System User (u) for the yearly period (t)
NCPD (u)(t) = Average Non-coincident Peak Demand of the Transmission System User (u) for the yearly period (t)
[clause 65]
2. The Annual Transmission Charge payable by Transmission System User shall be computed in accordance with the following formula:
2.1. ATC(u)(t) = TTSC(t) X ([Base TCR(u)](t) / Σ u=1 to n [Base TCR(u)](t))
Where,
ATC(u)(t) = Annual Transmission Charges to be shared by Transmission System User (u) for the yearly period (t)
Base TCR (u) = [CPD(u)(t) + NCPD(u)(t)] /2
Where,
Base TCR represents the Base Transmission Capacity Right of each Transmission System User (u) for the yearly period (t)
CPD (u)(t) = Average Coincident Peak Demand of the Transmission System User (u) for the yearly period (t)
NCPD (u)(t) = Average Non-coincident Peak Demand of the Transmission System User (u) for the yearly period (t)

Treatment of losses
1. The energy losses in the intra-State transmission system, as determined by SLDC, shall be considered as Transmission Losses and borne by the Transmission System Users in proportion to their usage of the intra-State transmission system:
2. The quantum of energy consumed by the auxiliary equipment of a transmission sub-station and the station transformer losses within the sub-station shall not be accounted for under the Transmission Losses
3. Provided further that the energy consumed for supply of power by the transmission sub-station to the associated offices of the Licensee, its housing colony and other facilities, and for construction works at the sub-station, shall not be considered as energy consumed by the auxiliary equipment of a transmission sub-station.
[clause 69]
2. The quantum of energy consumed by the auxiliary equipment of a transmission sub-station and the station transformer losses within the sub-station shall not be accounted for under the Transmission Losses
3. Provided further that the energy consumed for supply of power by the transmission sub-station to the associated offices of the Licensee, its housing colony and other facilities, and for construction works at the sub-station, shall not be considered as energy consumed by the auxiliary equipment of a transmission sub-station.
[clause 69]
Incentive
For payment of bills of transmission charges within 7 days of presentation of bills, through Letter of Credit or otherwise or through NEFT/RTGS, a rebate of 1% on billed amount, excluding the taxes, cess, duties, etc., shall be allowed.
[clause 36]
[clause 36]
Reactive Energy Charges
1. A Generating Station shall inject/absorb the reactive energy in to the grid on the basis of machine capability as per the directions of MSLDC.
2. Reactive energy exchange, only if made as per the directions of MSLDC, for the applicable duration (injection or absorption) shall be compensated/levied by the MSLDC to the Generating Station, as specified in the MERC (State Grid Code) Regulations, 2006.
3. The Transmission System Users shall be subjected to Incentive/Disincentive to be compensated/levied by the MSLDC for maintaining the reactive energy balance in the transmission system, as specified in the MERC (State Grid Code) Regulations, 2006.
[clause 70]
2. Reactive energy exchange, only if made as per the directions of MSLDC, for the applicable duration (injection or absorption) shall be compensated/levied by the MSLDC to the Generating Station, as specified in the MERC (State Grid Code) Regulations, 2006.
3. The Transmission System Users shall be subjected to Incentive/Disincentive to be compensated/levied by the MSLDC for maintaining the reactive energy balance in the transmission system, as specified in the MERC (State Grid Code) Regulations, 2006.
