Abstract [en]

Hydropower is the largest producer of

renewable electricity in Sweden with a

yearly mean production of 65TWh. A key

aspect of hydropower is its’ ability to

store energy in dams and therefore being

able to adjust the production to the

energy consumption. Since each river

system in Sweden is different each dam

is unique. The focus on dam safety

issues has increased in Sweden during

the last 15 years. SMHI has created more

accurate flow models and new dam safety

ideas have been obtained though

international collaboration. The RIDAS

guidelines for dam safety govern the

hydro power companies’ dam safety work.

Dams are rated after the consequence of

a dam breach. The consequence class of a

dam puts demands on the backup system. A

consequence class 1 dam is to be

dimensioned to withstand a 10000 year

flow and is also required to have a

backup system installed. In accordance

to the demands set by RIDAS, Fortum have

decided to do dam investigations called

FDU on a regular basis. Due to a focus

on dam safety Fortum are conducting dam

safety increasing projects on several of

their dams. Backup systems can be

designed in many different ways and must

be customized to fit the properties of

the dam. By analyzing the river system,

how the dam is designed and what the

surroundings look like conclusions about

what is needed in terms of backup system

can be drawn.
