Promotion of SHP with an installed capacity up to 10 MWLobbying for SHP on European level (European Parliament, European Commission, etc.)Support for national SHP associationsInformation, dissemination, and awareness raising for SHP issues (publications, workshops, conferences)Research on SHP issues (EC-contracts in different programs) ESHA OBJECTIVES
SMALL HYDRO DEFINITION “Hydroelectric power plant with an installed (maximum) capacity up to 10 MW”
What do we pay for? Power P [kW] ~ Q [m3/s] x H [m] x 7,8 P = electrical power output Q = rated discharge H = net head Energy Rule of thumb for run-of-river plants E [kWh] = P [kW] x 4.500 [h]

Potential economic - exploited ~ 250 TWh/year ~ 55 GW installed capacity technical – economic ~ 450 TWh/year ~ 100 GW installed capacity
Perspectives • multipurpose plants (electricity production combined with drinking water supply systems, waste water treatment plants, irrigation channels) • low-head and very low head plants. It is estimated that 1 to 1.5 GW can be installed in Europe using existing dams, weirs, irrigation infrastructures etc, with a very low environmental impact as the infrastructure already exists
