This document is the conclusion and appendix of the Hendrina Power Station Energy Services Consolidated Life-ex Report. It evaluates the feasibility and requirements for extending the operational life of the coal-fired power station, comparing the costs and risks of life extension against the construction of new plants.

• Life extension programs are presented as a method to reverse aging effects in coal-fired power plants, allowing for cost-effective operation beyond their traditional lifespan. Such programs are generally less expensive, involve fewer siting and environmental complications, and present lower financial risk than new construction.
• The process for determining the necessary equipment modifications for life extension requires a combination of reviewing operating history, visual inspections of components, and non-destructive tests. In cases where historical documentation was missing, the study relied on interviews with plant personnel.
• The study notes that while some units were used as samples to simplify the planning effort, aging effects are unique to each unit due to differences in design, history, and maintenance practices. Consequently, even near-twin units may exhibit substantial differences in the remaining life of major components.
• Siemens recommends extending the operation of the power station to 2035 or longer by modernizing outdated and life-exhausted components. This option is estimated to cost approximately one-third of the cost of investing in a new plant, and the existing infrastructure is deemed sound for this modernization.
• Siemens explicitly advises against increasing the capacity of the boilers. However, it suggests that overall plant efficiency can be improved through better maintenance, repair, and replacements, and recommends implementing 'capacity improving solutions' during scheduled maintenance to minimize risk and cost.
• The report clarifies that the costs provided for different scenarios are approximations rather than exact prices, as the study relied on simplified work and assumptions. Exact pricing would require further confirmation.
