Pre-requisites:

  • Grid Connectivity.
  • Installation of Special Energy Meter (ABT Meter ) of 0.2s accuracy or as specified by the concerned SLDC and change the existing CT / PT to be compatible with it for recording flow of Energy, Demand, Voltage, Reactive energy, Average frequency at Fifteen Minute time blocks .

Statutory Requirements:

  • Member Client Agreement.
  • Client Registration and deposit of Annual non refundable Subscription Fee of Rs. One Lakh Only. [Plus Service Tax @ 12.36%, & signing Risk Disclosure.
  • NOC /Standing Clearance from State Load Dispatch Center (SLDC) in PX1 format .

  • The Nodal RLDC Schedules the power for TAM.

Delivery of Power

1. FOR DAM

  • The Exchange prepares the schedule based on the ATC, MCP & MCV. The Final Schedule is given by the Power Exchange to the NLDC who in turn sends it to respective RLDC's. The RLDC's incorporates the IEX schedule in their schedule and sends the same to respective SLDC. SLDC delivers the schedule to concerned buyers or sellers. Once the schedule is delivered, it is deemed that power has been delivered.
  • The actual injection/ drawl are recorded by the Special Energy Meters installed at the point of injection / drawl. The meter reading is collected through telemeter or by joint inspection.

2. FOR TAM

  • The Nodal RLDC prepares the schedule based on the application sent by IEX along with SLDC clearance received from both buyer and seller, and sends the same to SLDC of Buyer State, RLDC of Seller region and intervening RLDC's (if any). The RLDC of seller region incorporates the Nodal RLDC's schedule in their schedule and sends it to seller's state SLDC. Once the schedule is delivered, it is deemed that the power has been delivered. The actual injection/ drawl are recorded by the Special Energy Meters installed at the point of injection / drawl. The meter reading is collected through telemeter or by joint inspection.

Settlement of deviation from Schedule

Any deviation from the schedule is either payable/receivable by the client and is settled by the RLDC/SLDC under the Unscheduled Interchange (UI) mechanism on weekly basis based on telemeter data / joint meter reading. UI settlement is compiled by RLDC and sent to SLDC's after approval of Regional Power Committee (RPC).
