How are wheeling charges computed? Give the procedure for source connected at 33kV and consumer connected at 11 kV.

 Wheeling charges refer to the fees charged by the transmission or distribution utility for the transportation of electricity from one point of the grid to another. These charges are typically incurred when electricity is wheeled from a source, such as a generating station or another distribution network, to a consumer or another distribution network. The computation of wheeling charges involves various factors, including the distance of transmission, the voltage levels involved, and the applicable regulations or tariffs. Here's the procedure for computing wheeling charges in the scenario where the source is connected at 33 kV and the consumer is connected at 11 kV:

1. Identify Distance and Voltage Levels: Determine the distance between the source and the consumer, as well as the voltage levels at which the source and consumer are connected to the grid. In this scenario, the source is connected at 33 kV, and the consumer is connected at 11 kV.
2. Determine Applicable Tariffs or Regulations: Consult the relevant tariffs or regulations established by the regulatory authority, such as the State Electricity Regulatory Commission (SERC) or the Central Electricity Regulatory Commission (CERC). These tariffs or regulations may specify the methodology for computing wheeling charges based on factors such as distance, voltage levels, peak demand, and other parameters.
3. Calculate Transmission Losses: Determine the transmission losses incurred during the wheeling of electricity from the source to the consumer. Transmission losses depend on factors such as the distance of transmission, the voltage levels involved, and the efficiency of the transmission infrastructure. Transmission losses are typically expressed as a percentage of the total energy transmitted.
4. Compute Wheeling Charges: Once the relevant parameters are identified, apply the methodology specified in the tariffs or regulations to compute the wheeling charges. The computation may involve a combination of fixed charges, variable charges, and surcharges based on factors such as the distance of transmission, voltage levels, transmission losses, and any other applicable criteria.
5. Allocate Charges between Source and Consumer: Allocate the computed wheeling charges between the source and the consumer based on the terms of the power purchase agreement (PPA) or the wheeling agreement between the parties involved. The allocation may be based on factors such as the contractual arrangements, the proportion of energy wheeled, and any other relevant considerations.
6. Invoice and Payment: Prepare invoices detailing the wheeling charges incurred by the parties involved, including any applicable taxes or surcharges. Ensure timely payment of the wheeling charges in accordance with the terms and conditions specified in the agreements or regulations.

It's important to note that the computation of wheeling charges may vary depending on the specific regulations, tariffs, contractual arrangements, and other factors applicable in a particular jurisdiction or scenario. DISCOMs and other stakeholders involved in wheeling arrangements should consult the relevant authorities and agreements to ensure compliance with applicable requirements and fair allocation of charges.
