Coby, If my smiple computations are right, the site could support at 100% annual firm output of 250 kW project. and more if you really intend to harness the full potential of the stream (up to the optimum capacity if there is a chance to sell the output to the grid company). But, it is an off-grid system, get only what you need, but do add for the furture demand growth. say for the life of the system or until there is grid connection.
For your site, you can select any of the turbine types: Turgo, Francis or Crossflow type turbine. The final type of selected turbine and the pipe sizes will be determined after you have decided on the output of the project. Where in the Pacific Northwest are you?
