The RSA power system again became constrained in Q1-2019 with Eskom needing to loadshed (to Stage 4 at times). Causes of leadshedding have been cited as high unplanned plant failures on the thermal coal fleet, depleted diesel (OCGTs) and water (pumped storage) combined with the loss of Cahora Bassa import from Mozambique. This has been the most intensive loadshedding experienced in RSA with 595 GWh of load shed just in March 2019 of the total 769 GWh in Q1-2019 (there was 1325 GWh of loadshedding throughout 2015).
