The blue areas represent lakes in the Waitaki Hydro Scheme along with the system of
connecting rivers and canals. The green/white boxes represent the generators at each
The GUI interface provides a simple yet powerful means of initializing the input

Once the initial operating conditions have been configured, a mathematical solver is
used to determine the optimum operation conditions for the next 2 to 7 days of generation.
