Forecasting & Scheduling Code

• Qualified Coordinating Agency (QCA) shall provide Day-ahead and Week ahead by 9 AM everyday schedule to the SLDC.
• Day-ahead schedule for solar– At intervals of 15 minutes for the next day, starting from 05:30 hrs to 19:00 hrs of that day. Maximum 9 revision on that day allowed
• Day-ahead schedule for wind– At intervals of 15 minutes for the next day, starting from 00:00 hrs of that day. Maximum 16 revision on that day allowed
• One revision for each of one-and-a-half-hour time block subject to respective revisions on a day.
• Revision can be done by giving notice; effective from the 4^th time block -the1^st being when notice was given.

Role of QCA and Implementation

• One QCA for each pooling sub-station or generating station registered with SLDC.
• Minimum 1 year experience in power Forecasting and Scheduling.
• QCA shall be the single point of contact with respect to:
  • Meter reading, data collection and its communication.
  • Provide schedule on behalf of generators to transmission licensee, State transmission licensee, distribution licensee networks.
  • Coordination between distribution licensee, SLDC and other agencies.
  • Commercial settlements between generators and their counterparties.
  • All other ancillary or incidental matters.
