Hi~, here is a quick way to insert the turbine locations according to the certain coordinates and hub height: Just copy the WTG ID, X coordinates, Y coordinates and Hub height in the EXCEL sheet, then right click on the project items that you want to add your turbines in the WAsP program, on the list, you can select "Insert N turbine sites from the clipboard", mission done! So quick, right? :) I have also tried to add the turbines following your way, it also works. Maybe you can try again and make sure you save the coordintas and hub height in format of VALUE, so that WAsP can read them correctly.
