This document is a technical section of the Hendrina Power Station Consolidated Life-ex Report, detailing specific technical recommendations, required interventions, and cost projections to extend the operational life of the power plant until 2025. It covers the maintenance and replacement of energy services, electrical plant, common plant areas, and generators.

• To ensure the power plant can run until 2025, Siemens E P IE estimates the implementation cost for recommendations in the C&I Plant Area (including filtration, demin plants, and DCS monitoring) at approximately R 92,981,084 for all units and common plant.
• The plant's operational life is effectively limited to June 2018 unless Ash Dam 6 is constructed and commissioned by that date. Construction is recommended to begin in 2016 to avoid delays.
• The current population of MV motors is described as being in very poor condition and past their economic and reliable life, having operated for approximately 40 years (double their design life). A replacement program is necessary for life extension to 2025, prioritizing ID fan motors, EFP motors, PA fan motors, ash pump motors, FD fan motors, and CW pump motors.
• Original unit-plant related LV motors are over 40 years old (against a 20-year design life) and are considered uneconomical to operate, requiring immediate high-priority replacement.
• For the generators, the report presents three scenarios for operation until 2025. Scenario A (keeping current gas/water-cooled generators) is estimated at 96.8 million EUR (1.4036 billion ZAR) over 10 years but carries high technical risk. Scenario B (replacing 3 generators and adding a spare air-cooled unit) is identified as the most advantageous due to lower risk and OPEX. Scenario C (replacing all 10 units) is deemed economically non-viable for a 10-year extension.
• Significant structural risks are identified in the cooling towers, specifically severe spalls on circular columns of Cooling Towers 2, 5, 7, and 8, which could lead to sectional or overall structure failure within 2 years if not rectified.
• The report notes a failure to comply with Eskom mandatory Standard 240-56358993 regarding power transformer maintenance, which led to a loss of oil seal integrity and excessive moisture, necessitating urgent refurbishment or replacement of auxiliary transformers.
