Lesson
Accurate cost estimates, including for contingencies, and effective utilization of loan savings are critical to the attainment of intended project results and timely financial closing. The actual contract price was lower than the amount estimated because of the inaccuracy of the engineering cost estimate and contingency estimates. Cost savings, however, were effectively utilized through minor changes in the project, further enhancing the achievement of project outcomes and outputs. Eligible expenses should be clarified early on, so as not to delay the project financial closing.

Lesson
Climate risk assessments must be undertaken during project preparation, with results factored into the project design and budgets. The project experienced unforeseen landslides, pointing out the need to (i) improve climate modelling at design stage to incorporate potential climate change impacts on frequency and severity of landslide hazards for projects located in mountainous areas, and (ii) ensure adequate budget or contingency for potential increase of land acquisition during implementation.

Resource constraints can impede the participation of smaller firms in ADB procurement as well as hinderCapacity development of counterpart agencies. Smaller firms struggled to respond appropriately in some bidding processes, which resulted in their being considered ineligible to participate. The project implementation unit experienced resource constraints, which hindered sustainedCapacity development throughout the project and the participation of outer islands officials in the training activities.

Budget approval and procurement of new technologies being piloted could take time and cause implementation delays; when installed, rigorous monitoring of the performance of the new technologies is required to ascertain benefits and draw lessons from the pilot experience. In implementing the four pilot smart grid projects, substantial delays occurred due to the lengthy budget approval process and the procurement requirement of open competitive bidding while allowing international bidder participation.

Project Name: Sustainable Energy Access in Eastern Indonesia—Electricity Grid Development Program

Lesson
The cost categories required to be reported in the audited program financial statements (APFS) need to align with the categorization at appraisal so as not to cause problems in reporting. PLN faced difficulty in estimating the financing charges during implementation at appraisal stage. In addition, PLN raised a concern on the disclosure provision regarding APFS due to confidentiality requirements. The cost categories reported in the APFS were not aligned with the categorization used at appraisal, due to which changes to reporting formats were needed.

Lesson
Project costing at design stage should realiably estimate the costs of all civil and other engineering costs and provide allowance for foreign currency fluctuations. The actual cost of one irrigation scheme turned out some $10 million greater than estimated at approval. This resulted in significant revision to the subproject design. The revision also incorporated the appreciation in special drawing rights against the US dollar and the domestic and international inflation that pushed down the real value of project resources.

Lesson
The periodic maintenance payment rates may be standardized for future use. This project incorporated maintenance payments for the first year, allocated at prefixed rates, and with provision for an annual increase in subsequent years. Comparing the periodic maintenance payments made to the contractors with the actual expenditure incurred by the contractors, there is basis for standardizing periodic maintenance payment rates.

Lesson
A detailed market assessment is necessary to come up with reliable cost estimates. The actual costs deviated significantly from the original estimates, aggregating to only $29.35 million or 49% of the $60 million total estimated cost. This was mainly because of the nearly 30% drop in the actual cost of equipment realized through the international competitive bidding process, the reduction in the number of distribution transformers installed, and the reduction in the scope of underground cable installation actually undertaken.

Significant implementation delays under both tranches underscore three important points: (i) weather conditions stop works during winter months and even interrupt work during other months, (ii) proper planning is essential so that issues such as inadequate access infrastructure can be taken care of sufficiently in advance, and (iii) extensive geological surveys and testing are crucial in the Himalayan region prior to the detailed project report stage.
