EnviPEAK will address the changes that are expected in the operation of Norwegian hydropower plants as a consequence of the development of other energy sources, such as wind power. The main objective of EnviPEAK is to develop knowledge and tools to analyse, predict and mitigate environmental impacts from rapid and frequent changes in hydropower production regimes ('hydropeaking').

Increased electricity trade with Europe and the increased production of wind power is expected to lead to changes in the operation of Norwegian hydropower plants. Future scenarios predict more flexible operation of hydropower systems which may lead to more frequent and rapid changes in water flow and water levels in rivers, lakes, reservoirs and fjords. The main focus is the impacts in rivers. These variations will change the living conditions for fish, benthic animals and other animals and plants living in and near regulated rivers. There is a great need to analyse and predict these impacts, define the tolerance levels and find cost-efficient mitigation strategies.
