The construction cost is the amount of money required to build the dam, its power plant and any associated infrastructure needed to make it operational, such as new access roads. Do not include the recurring costs of maintaining and operating the dam. The HydroCalculator will do that for you. See the article on transmission infrastructure for instructions on how enter any large new power lines that may be necessary.
You may want to analyze the impact of cost overruns on the dam's feasibility. Though some dams are finished for less than the estimated budget, that outcome is rare. A 1996 World Bank study found that hydro projects funded by the bank cost an average of 27% more than estimated.
