37. 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).
