 *Turbine, generator, controller come from a specialist producers
 *Pipeline and civil works can be done by companies not necessarily specialised in mhp. Whereby experience is always an advantage.
 *Hills and all year round water flow provide good hydropower conditions
-*Waterfalls are typical indicators for mhp potential
+==== Suitable areas for mhp: ====
 *A river which cascades down on a short distance can be suitable for mhp
 *Irrigation canals can have good hydropower potential if there is some drop in height
 *mhp feasibility (pre-) study
-*mhp planning

 *construction supervision
-*installation electromechanical equipment
