Lesson
Knowledge transfer ensures the sustainability. As the newly built grid connected HPPs are using advanced technology, technicians will require new skills to ensure proper O&M. Therefore, further onsite training will be needed to ensure the sustainability of the program’s operational life, preferably within the defect liability period.

Lesson
The cost overruns indicate the importance of sound engineering design and value engineering that can (i) support more accurate cost estimates; (ii) preclude or minimize minor changes in the project’s scope or variations to contracts during construction; and (iii) set a more reasonable and realistic implementation schedule. Factors that contributed directly to the cost overruns include the higher cost of labor and materials than estimated at appraisal, the significant JPY depreciation, the inadequate program preparation, and the incomplete engineering design.

Lesson
Procurement is critical in infrastructure projects, requiring preparation by project/program design consultants and close supervision by consultants, the government and executing agencies, and ADB. Subprojects suffered major delays because of weak procurement, leading to substantive time and cost overruns. Program implementation team from ADB should have been more proactive in assisting in the implementation of startup activities such as consultant recruitment and preparation of engineering designs.
