Worked example 01 records SAPP's November 2025 market report as saying an outage "in the Nampower network" on 11 and 13 November "affected the transmission of power from NTCSA to ZESCO" (SAPP-K-0002 there). The quarterly report places converter work on the Caprivi Link on the same dates. That the two are the same event is inferred from the matching dates; no SAPP document links them.
