Repairs at the Antonio Guiteras Thermoelectric Plant in Cuba have faced ongoing technical challenges. Initially, maintenance timelines were extended after a leak was detected in the economizer during a hydraulic test. General director Román Pérez Castañeda noted that technicians had to develop new strategies to address the damage, which might involve more than simple pipe replacement.

Subsequent reports indicate a new issue involving a failure in the high-temperature reheater (RAT) following a sudden loss of water in the boiler. Workers identified six defects in this area, requiring the cutting and replacement of damaged pipes. Following pipe replacement, crews must perform welding and conduct metallographic and hydraulic control tests. If successful, the plant, a critical component of the National Electric System, could restart by early October.
