The Hendrina Power Station Consolidated Life-ex Report evaluates the technical condition of various plant systems to determine the requirements for extending the station's operational life to 2025. The report identifies critical failures in turbine auxiliaries, pump casings, electrical motors, and ash disposal facilities, while noting that many systems can operate until 2025 provided that maintenance backlogs are addressed and specific component replacements are executed.

• The turbine plant's overall status indicates that while operation until 2025 is critical, extending the life until 2035 without replacement is not possible.
• Condenser tubes, particularly in the air extraction zone, require replacement to ensure operation until 2025; other tubes show wall loss up to 40% and may last until 2025 with regular maintenance.
• Between 2000 and 2012, 76 unit trips or operating incidents occurred due to equipment failure (47 incidents) and human error (29 incidents), with the primary causes being high condenser vacuum, condenser tube leaks, and condenser high level.
• High Pressure (HP) and Low Pressure (LP) heaters with tube plug rates of 10% or higher require replacement for continued operation until 2025. Specifically, 12 out of 60 HP heaters across the station meet this criteria.
• Main Steam Feed Pump (SFP) and Condensate Extraction Pump (CEP) casings have a 35-year life limit and most are beyond this limit, making maintenance increasingly difficult due to inferior materials and physical distortions.
• Original unit-plant related LV motors are considered uneconomical to operate and are not acceptable for operation until 2025, requiring immediate high-priority replacement.
• The station's MV PILCSWA cables are systematically unreliable, leading to previous replacement programs by Eskom, particularly for mill motors and ash water return pumps.
• The current ash dam complex is predicted to be capable of containing ash production only until the middle of 2018, necessitating the construction of Ash Dam 6 by 2016 or 2017 to avoid interrupted operations.
• Cooling Tower 4 exhibits multiple long vertical cracks in the upper zone, which is a serious concern as it may indicate an inability to resist wind loadings.
• The North Sedimentation plant is non-functioning, which results in uncontrollable cooling water quality and adversely affects the condensers.
