Evenwhen various states are not so eager to provide open access in transmission, the Central Electricity regulatory Commission (Cerc) has issued amended stricter regulations for Open Access in inter-State Transmission. These regulations will come into force from April 1. Cerc has proposed Rs 80 per megawatt hour (Mwh) of transmission charges for bilateral, intra-regional open access, for bilateral, between adjacent regions open access Rs 160 per Mwh and for bilateral, wheeling through one or more intervening regions open access Rs 240/Mwh.

Henceforth, the National Load Despatch Centre (NLDC) or a Regional Load Despatch Centre (RLDC), as the case may be, will not grant open access for sale of electricity from entities and associates of such entities, defaulting in payment of Unscheduled Interchange (UI) charges, transmission charges, reactive energy charges, congestion charges and fee and charges for NLDC or RLDC including the Unified Load Despatch and Communication Schemes, when so advised by the CERC. A person seeking open access may be disqualified if found misuing the transmission corridor booked for open access or repeated non-utilization of opportunities available.

The RLDC in case of regional entity and the State Load Despatch Centre (SLDC) in case of intra-state entity will monitor any deviations from the schedules to verify the possibility of gaming by any person and on suspecting any gaming it shall report to the Cerc. These regulations will be applied to bilateral transaction which includes a transaction for exchange of energy (MWh) between a specified buyer and a specified seller, directly or through a trading licensee or discovered at power exchange through anonymous bidding, from a specified point of injection to a specified point of drawal for a fixed or varying quantum of power (mw) for any time period during a month.

Moreover, the person seeking cancellation or curtailment of open access will pay the transmission charges for the notice period of two days in accordance with the schedule originally approved by the nodal agency. The cancellation or curtailment of schedule of a day will be implemented so that quantum of cancellation or curtailment will not be less than 10% of the schedule applicable when cancellation or curtailment is to be implemented. Provided that in case of transactions involving wind generation power plants as the identified source of supply of electricity, curtailment or enhancement of schedule of a day will be implemented so that curtailment or enhancement of schedule will not be less than 10% of the schedule applicable when curtailment or enhancement is to be implemented.
