Solar and wind generators in India must submit day-ahead schedules by 09:30 or 10:00 AM. During the operational day, up to 16 intra-day revisions are permitted. Revisions become effective only after 6 time blocks (1.5 hours) from the revision submission timestamp.
What is the 6-block revision lead rule?
Under CERC and state grid codes, any schedule revision submitted to the SLDC becomes effective from the 6th time block following the block in which the revision was submitted. If a plant operator submits a revision during Block 30 (07:15–07:30 AM), the modified schedule will take effect starting at Block 36 (08:45–09:00 AM).
During the intervening 5 blocks (75 minutes), the generator remains legally bound to its previously active schedule.
What happens if the SLDC scheduling portal goes down?
When an SLDC portal experiences a server outage or timeout during a revision window, the generator must document the failure immediately. Standard operating procedure requires capturing timestamped error logs and dispatching the revision file via official registered email to the SLDC control room shift in-charge before gate closure.
REFlux automates this failover process, logging cryptographic timestamps and generating formal dispute audit receipts.
