This consolidated report, compiled by Siemens for Eskom, evaluates the requirements and costs for extending the operational life of the Hendrina Power Station. The study examines three scenarios: continuing operations until 2025, extending operations until 2035, and implementing capacity increases through system improvements. Based on physical inspections and desktop studies, the report finds the plant's units 1-10 to be in generally poor condition, with significant output losses due to operating limitations and forced outages.

• The overall condition of units 1-10 at the Hendrina Power Station is described as poor, with operating limitations such as cropped turbine stages causing a 500 MW loss in plant capability, and forced outages adding another 250 to 500 MW in losses.
• Siemens recommends extending the power station's operation to 2035 or longer through immediate investment in modernizing life-exhausted, outdated, and maintenance-intensive components. This option is estimated to cost approximately one-third of the cost of building a new plant and would reduce annual maintenance costs by at least R100 million.
• Significant capital investment is required for the Boiler Plant Area of Units 1-5 for both the 2025 and 2035 scenarios, including improvements to gas flow distribution, Low NOx Burner retrofits, modular replacement of tube banks (primary SH and Economiser), and the replacement of the complete flue.
• For Units 6-10 in the Boiler Plant Area, critical requirements for 2025 and 2035 include the replacement of the Economizer Element, Superheater 2 Outlet Header, Attemperator I and II, and various headers and piping related to Superheater 3 and 4.
• The Draught Group requirements for both Units 1-5 and 6-10 include airheater pack changes, replacement of FD and ID Fan bearing housings, and the implementation of a complete FGD system by 2035.
• Turbine plant recommendations include replacing life-exhausted HP-turbine internals and HP-valves, LP-Turbine internals, and Boiler feed pump turbines with modern designs to reduce maintenance costs and increase efficiency.
• Electrical and C&I upgrades include replacing the DCS, upgrading measurement and metering to meet EMDAS standards to avoid environmental penalties, and replacing generators with new air-cooled footprint models.
• Essential civil and environmental works include repairing coal staithes, upgrading the North Desalination Plant, and erecting a new ash dam, which is required for operation after 2022 regardless of the life-extension study.
