Base case
- Central grid connection
- A mini hydro project at an existing dam on moderate-sized lake
- Gross head is 15 m
- Maximum tailwater effect is 2.0 m
- A residual flow of 0.5 m3/s must be maintained
- Percent time firm flow available is 100%
- A single Kaplan turbine with a design flow rate of 3 m3/s will be installed
- Kaplan turbine design coefficient is 4.5
- Cost of turbine and civil works (penstock, dam modifications, etc.) is $5,000/kW
- Flow-duration curve data are as follows:
- Maximum hydraulic losses are around 7%, miscellaneous losses are around 2%
- Generator efficiency is 95.0%
- Power system availability is 96.0%
- Electricity will be sold at $0.10/kWh
- O&M for water rights, land usage, and a part-time operator is $30,000 annually
