OPEN ACCESS: DEFINITION AS PER ELECTRICITY ACT, 2003 “ licensee “ means a person who has been granted a licence under section 14; The Appropriate Commission may, on application made to it under section 15, grant any person licence to any person - (a) to transmit electricity as a transmission licensee; or (b) to distribute electricity as a distribution licensee; or (c) to undertake trading in electricity as an electricity trader, in any area which may be specified in the licence:

OPEN ACCESS: DEFINITION AS PER ELECTRICITY ACT, 2003 "consumer" means any person who is supplied with electricity for his own use by a licensee or the Government or by any other person engaged in the business of supplying electricity to the public under this Act or any other law for the time being in force and includes any person whose premises are for the time being connected for the purpose of receiving electricity with the works of a licensee, the Government or such other person, as the case may be;

OPEN ACCESS: DEFINITION AS PER ELECTRICITY ACT, 2003 No person shall (a) transmit electricity; or (b) distribute electricity; or (c) undertake trading in electricity, unless he is authorised to do so by a licence issued under section 14, or is exempt under section 13.

CERC Open Access Regulations, Subject to any other regulations specified by the Commission, the long-term customer shall have first priority for using the inter-State transmission system for the designated use. These Regulations shall apply for utilization of surplus capacity available thereafter on the inter-State transmission system by virtue of- (a) Inherent design margins; (a) Inherent design margins; (b) Margins available due to variations in power flows; (c ) Margins available due to in-built spare transmission capacity created to cater to future load growth or generation addition:

Power Exchange Power Exchange Presently CERC has allowed only Day ahead Market At present CERC has allowed only National level operated Power exchanges. In due course if need arises Regional level operated exchanges will come. In power exchanges, as per CERC norms the price discovery is through Double sided closed auction. Collective transaction means a set of transactions discovered in power exchange through anonymous, simultaneous competitive bidding by buyers and sellers For Power Exchange transactions the Nodal agency will be National Load Despatch Centre (NLDC).

Power Exchange Generally the ATC declaration is done by NLDC on its web site every day.Generally the ATC declaration is done by NLDC on its web site every day. Depending on the corridor availabilities the solution is found out by the power exchanges and the allowed trades will be intimated to NLDC.Depending on the corridor availabilities the solution is found out by the power exchanges and the allowed trades will be intimated to NLDC. If there is no congestion NLDC will accept the trades and issue the schedules to the power exchange and the same will be implemented in RLDC schedules.If there is no congestion NLDC will accept the trades and issue the schedules to the power exchange and the same will be implemented in RLDC schedules.
