The National Transmission Company South Africa (NTCSA) has confirmed what it describes as a “temporary bottleneck” in curtailment payments to independent power producers (IPPs), with about R2-billion of such compensation claims currently undergoing “verification and settlement”. This confirmation came only days after EE Business Intelligence MD and energy analyst Chris Yelland wrote that renewables IPPs had experienced a sharp increase in curtailment instructions from Eskom in 2026 and were growing increasingly concerned about a lack of transparency in the methodology being used, as well as delayed reimbursements.
