EU Water Framework Directive Physical restoration Restoration related to hydropower Restoration related to timber floating Restoration related to road passages Restoration of hydromorphology Restoration related to water drainage 5/30/2017 2

Restoration related to hydropower Installed capacity Hydropower in Sweden - 2 100 stations produces 40% of Small hydropower (<10MW) the total electricity - 10% of the stations produces > Large hydropower (>10MW ) 90% hydro electric power 5/30/2017

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 5/30/2017

Restoration related to hydropower 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 5/30/2017

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 5/30/2017

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 5/30/2017

Restoration of lakes Triple lakes, northern Sweden • Cutting reed • Creating spawning habitats for arctic char ( Salvelinus alpinus) • Timber floating-restoration in inflowing rivers Foto: County Administration Board of Jämtlands län • Creating fish ways in rivers connected to these lakes 2017-05-30 15

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) 5/30/2017 16

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. 5/30/2017 17
