Background
Runner Litjfossen power plant
Residual lifetime calculations on type of damage S2
– Cavitation Runner Litjfossen power plant
Ca. 99% of Norway’s energy is produced by hydropower distributed on 1476 hydroelectric
power plants pr. 01.01.2014. In order to maintain the operation of the hydropower plants,
maintenance and reinvestments is necessary.
A technical-economic analysis of reinvestment requirements is implemented for a better
basis for the assessments and decisions to be adopted by maintenance and reinvestments in
the power industry.
The plant, which is analyzed in this project is Litjfossen power plant. Litjfossen power
plant was put into operation in 1982 and operated by TrønderEnergi. The plant has been
in operation for over 30 years without major reinvestments and the risk of failure is
increasing. The main objective of the task is to perform a technical-economic analysis on
Litjfossen power plant to better the decision-making basis for the relevant maintenance and
reinvestment options available.
The task will include an overarching picture of the whole station with a main focus on
assessing the components with the highest risk of failure.
