300 MW reservoir project: planning to commissioning
Short answer
Steps are basin master plan and site identification, pre‑feasibility and feasibility studies, EIA approval, PPA and financing, detailed design and tendering, pre‑construction (land, resettlement, access), construction of dam/spillway/powerhouse, reservoir impounding, testing and commissioning, and operation with dam safety and environmental monitoring.
You are developing a 300 MW reservoir type project in a river basin of Nepal. Briefly mention what steps you would follow from planning to commissioning of the project.
A 300 MW reservoir project is a large project; the steps from planning to commissioning are:
- Basin master plan and identification: Choose the dam site by desk study, topographic maps and satellite images (reconnaissance).
- Pre-feasibility study: Hydrology, geology, topography; compare dam sites, dam type, heights, and capacities; storage-yield curves; preliminary environment/resettlement study.
- Feasibility study: Detailed survey, drilling, hydrology and sediment, optimisation of dam height and installed capacity, design of dam, spillway, intake, tunnel and powerhouse, cost, EIA, resettlement plan, financial analysis.
- Licence, EIA approval, PPA and financing: Survey and generation licences, EIA approval, power purchase agreement, and finance (government, banks, development partners).
- Detailed design and tender: Final design and drawings, hydraulic model tests, and tender documents; select the contractors (civil, hydro-mechanical, electro-mechanical, transmission).
- Pre-construction work: Land acquisition, resettlement, access road, camp, power supply, diversion arrangements.
- Construction: River diversion, foundation treatment, dam, spillway, intake, tunnel, powerhouse, installation of turbines and generators, transmission line.
- Reservoir impounding, testing and commissioning: Fill reservoir in stages with monitoring, test machines, synchronise and run the plant.
- Operation and monitoring: Maintenance, dam safety, sediment and environmental monitoring.
