THE Hwange Thermal Power Station is making steady progress in restoring its operations following a technical fault caused by an acid ingress incident that affected some of its units earlier this month.
The fault, which occurred on 4 May affected Units 1, 2, 3, 4, and 6, disrupting the station’s output.
In a statement on Thursday, ZESA Holdings confirmed that repairs on the affected units have been completed.
“Hwange Power Station experienced a technical fault on 4 May 2025 following an acid ingress incident on Units 1, 2, 3, 4, and 6.
“At the time of the incident, the station was producing 498 megawatts (MW) of electricity,” reads the statement.
The power utility said all affected units have been repaired, with Units 1, 2, and 3 back online and generating a combined total of 212 MW.
“Unit 3 is still ramping up, and the total output from these three units is expected to reach 260 MW by midday, 14 May.
“Unit 4 has successfully passed all safety and performance tests after repairs and is scheduled to be reconnected to the grid on Thursday, 15 May, around midday,” reads the statement.
The power utility further highlighted that while Unit 6 returned to service on Friday 9 May, it unfortunately developed a separate, unrelated issue shortly after.
As a result, it is offline and expected to return to service by 27 May 2025.
On Thursday, Hwange was producing 920MW with Kariba sitting at 400MW. Independent Power Producers are contributing 41MW with the total power generation at 1370MW.
