Scheduling

All transactions pursuant to grant of long-term open access and medium-term open access shall be carried out on day-ahead basis in accordance with the grid code by SLDC.

Metering

Interface energy meters shall be installed and maintained by the STU for open access in transmission by the distribution licensee  and for open access in distribution at the cost of the open access customers

The buyers and sellers of electricity shall absorb apportioned energy losses in the transmission and/or distribution system as estimated by the State Load Dispatch Centre. The energy losses shall be accounted for by providing a differential between schedules at the points of supply and drawal of electricity.

Imbalance Energy Charges

• For STOA: The UI rate for intra-state entity shall be 105% (for over-drawals or under-generation) and 95% (for under-drawals or over-generation) of inter-state UI rate.
• For LTOA and MTOA: Based on net metering on the periphery of each intra-state entity, composite accounts for Unscheduled Interchanges shall be issued for each intra-state entity on a weekly cycle.
• Any mismatch between the scheduled and the actual drawal at drawalpoints, and scheduled and the actual injection at injection points for the intra-state entities shall be determined by the State Load Despatch Centre and covered in the intra-state Unscheduled Interchanges accounting scheme.
• The Unscheduled Interchanges rates for intra-state entity shall be 105% (for over-drawals or under-generation) and 95% (for under-drawals or over-generation) of the inter-state Unscheduled Interchanges rates.

Reactive Energy Charges

The reactive energy drawals, injections and payment, receipt of the reactive energy charges by the open access customers, shall be in accordance with the relevant provisions of the Grid Code.
