This report provides an economic and technical evaluation for the life extension of the Hendrina Power Station, focusing on necessary interventions to maintain operations until 2025. It details required upgrades for boiler, turbine, electrical, and common plant areas, emphasizing the trade-offs between refurbishment and replacement to ensure reliability, safety, and legislative compliance.

• Modular replacement of boiler components for Units 1-5 has a payback period of less than five years based on Boiler Tube Leak (BTL) revenue loss, while the economizer modular replacement for Units 6-10 has a payback period of less than 10 years.
• For the turbine plant, the report suggests that changing to a new design would result in more than two-thirds of the investment costs being paid back within approximately one year.
• The station faces significant financial risk regarding the environmental (CO2 emissions) levy imposed by SARS due to non-compliance with NERSA measurement and metering standards. The difference between nominal and average annual output is estimated at 8,096 GWh, which at 3.5c/kWh represents a substantial annual cost of non-conformity.
• The Medium Voltage (MV) motor fleet is largely beyond its 20-year economical design life, leading to over 50 significant incidents per year and production losses exceeding 46,000 MWh annually due to unplanned outages.
• Regarding generator replacement scenarios for operation until 2025, Scenario B—replacing three generators (Units 8, 9, and 10) with air-cooled footprint generators and keeping seven as backup—is identified as providing the greatest savings benefit.
• To comply with the National Water Act and avoid infringing on Water Use Licenses, the report identifies the critical and immediate need to line the 7 Year Dam and two Raw Water dams.
• The current ash dam complex is predicted to reach capacity by the middle of 2018. To ensure uninterrupted operations, the construction of Ash Dam 6 must be brought forward to 2016 or 2017.
