SLDC/RLDC first-time charging & synchronization — documents, timeline & process
R6 · Commissioning & operations · ~45 days (indicative)
The grid operator's go-ahead to energise and synchronise your plant or line to the grid for the first time, then run the trial that makes your power 'firm'.
Joint interconnection study ~6 months before energisation → compliance file → charging clearance → first synchronization → trial run → firm scheduling.

Solarian expert note
Telemetry/protection non-compliance and un-charged upstream elements are the usual blockers. Infirm power window is ≤1 year from first sync.
