Hydropower in Sweden

• 2 100 stations produces 40% of

the total electricity

• 10% of the stations produces >

90% hydro electric power

Small hydropower (<10MW) Large hydropower (>10MW)

Installed capacity

Restoration related to hydropower

Legislation - Environmental code

• Many hydropower stations are old, need renovation, not

profitable and do not fulfill environmental terms

• Gives opportunities to remove dams and station – but still a

court decision is needed.

• Permission from environmental court necessary for hydropower

plants – authorities don´t take decision

• Best possible technology shall be used (if not the costs are too

high)

• Waiting for a new proposition regarding hydro electric power

Swedish dialogue on hydropower

• Balancing the demands from the

EU Renewable Energy Directive and the Water Framework Directive

• Ongoing process (5 year now)
• 30 organizations involved
• Consensus to produce:

a) Swedish strategy for actions b) Guideline on best available technique on fish passages and ecoflows

Restoration related to hydropower

Swedish dialogue on hydropower

• Swedish strategy for actions together with

the Swedish Energy Agency

• Report 2014
• All hydropower stations in Sweden divided

into 6 classes

• Class 1 – important for energy balance – low

demands for environmental measures. 255 stations.

• Class 6 – not important for energy balance

at all – full adaption to best available technology

Restoration related to hydropower

BAT – best available technology to improve fish passage

• Removal of dam and

hydropower stations

• Fishways
• Technical installations to

facilitate environmental flow regulation

• Maintenance & monitoring

Restoration of lakes

Triple lakes, northern Sweden

• Cutting reed
• Creating spawning habitats for

arctic char (Salvelinus alpinus)

• Timber floating-restoration in

inflowing rivers

• Creating fish ways in rivers

connected to these lakes

Restoration projects

• First restoration projects known – 1950’s
• Numerous smaller restoration projects since
• 5 large scale LIFE projects
• – timber floating (Vindel River LIFE)
• – dam removal and road culvert replacement (REMIBAR)
• – timber floating, dam removal, road culvert replacement (ReBorn)
• – dam removal, timber floating, re-meandering (UC4LIFE – Unio crassus)
• – restoration of three lakes (Triple lakes)

Promising future for restoration

• Hydropower companies will start a fund for environmental

actions at hydropower stations and related dams.

• They got reduced taxes from the government in return,

starting 2017.

• Still unknown how it will work.
• Governmental funding for other types of restoration.
