Quality of Hydropower

Water is more than just a natural resource – it is the basis and the energy of life Using the potential of water in a sustainable way is a key challange in the future

Water is not always at the right time at the right place available Electricity generation is not always at the right place at the right time

Quality of Hydropower

In addition to all other renewable options, hydropower has a very special quality

Hydropower is more than Electricity generation!

Quality of Hydropower Different types of HPP and functions

Run-of-river Hydro Power plants (HPP with no significant regulation reservoir) - Base Load Generation – with special equippement – Primary Voltage Control

Pondage Hydro Power Plants (run-of-river power station with small reservoir along the river which permit delaying the production of electricity for a few hours)

- Base and Peak Load Generation - – with special equippement – Primary Voltage Control
