Hydropower covered about 60% of the renewable electricity production. The total electricity consumption is expected to rise by 8% up to 3530 TWh from 2005 to 2050. With an increasing electricity production of the renewabl e energy sources of up to 1200 TWh or 34% of total electricity consumption in 2020, the contribution of HP to the electricity production from renewable sources will decrease to about 30%. Figure 1: Gross electricity consumption and electricity production by renewable sources in 2008 : (Source: EUROSTAT, Statistics in focus 56/2010) 3500 3000 17% 2500 1% 1% 2000 TWh 1500 21% 1000 60% 500 0 EU-27 gross electricity consumption Electricity production from renew ables Hydro Wind Geothermal Solar Biomass 1.2 Energy production and capacity of HP stations In 2008 the hydropower electricity production amounted to 327 TWh in the EU-27, at an installed capacity of 103 GW. Together with the candidate, associated countries (HR, MK, TR, IS, BA, ME, NO) and Switzerland the generation rises considerably to 554 TWh/a (EUROSTAT 2008), the total installed HP capacity reaching 161 GW (Table 1). 11418_wfd_hp_final 110512.docx Page 10 of 168 11418 According to the NREAPs for SHP th e electricity generation will increase by 11% and the installed capacity by 38% from 2005 to 2020. In the same time the electricity generation from large HP stations is expected to rise by 5% while an additional capacity of 16% will be installed. Table 1: Hydropower generation and installed capacities for SHP and LHP in 2008 Generation Capacity Hydro power [TWh] [GW] total SHP LHP total SHP LHP 2008 327 42.7 284 103 12.6 90 (EUROSTAT) EU-27 2020 370 55.0 315 131 16.7 114 (NREAP) EU-27 (2008, EUROSTAT) 554 52.7 501 161 13.9 147 candidate, associated countries, CH 1.3 Number of HP stations The total number of HP stations in the EU-27 amounts to about 23000 (Figure 2; Table 2). There are about 10 times more small (SHPP, P < 10 MW) than large HP plants (LHPP, P ≥ 10 MW). However, the generation of SHPP only amounts to 13% of the total generation of HP stations. Figure 2 shows this relation for the EU - 27. Today large HP stations account for 87% of the hydropower generation wit h only 9% of the stations. This discrepancy will further increase if the development follows the data in the NREAPs. The estimation for 2050 shows an increase in the number HP station by about 10% for large HP stations and by 25% for the number of SHP plants (with a rise in electricity generation of only 11%). The environmental impacts of hydropower are well known, as are corresponding mitigation measures. Especially the demand for river continuity within a chain of obstacles can only be fulfilled by reducing the number of obstacles, even if well-functioning fishways are built. Hence focus should be placed on development or reburbishment of large power plants. Example: The upgrading of a single LHP station in Iffezheim (Rhine) leads to an additional capacity of 38 MW with an estimated additional electricity generation of 122 GWh. This corresponds to about 190 SHPP of a capacity of 200 kW, a rather common size for SHP , and thus even if they were equipped with fishways to 190 additional obstacles in various rivers. 1.4 Contribution to CO 2 savings The total CO 2 emission in the EU-27 will decrease from 2005 to 2020 by 12% from 4.25 Gton to 3.71 Gton, while the decrease of CO 2 emission from electricity generation will be 18% from 1.34 Gton to 1.10 Gton. When calculating the change in contribution of SHP and LHP from 2005 to 2020 a slight increase can be recognized. Relative to the total CO 2 emission the contribution of SHP and LHP rise from 0.51% and 3.37% to 0.65% and 3.73% respectively or 0.5% in total. 11418_wfd_hp_final 110512.docx Page 11 of 168 11418 Relative to direct emissions from electricity generation in the EU-27 the CO 2 savings from SHP and LHP were 1.73% and 11.37% in 2005. These values will rise to 2.20% and 12.60 % respectively thus reducing the CO 2 emission together by an additional 1.8% in 2020.

Within certain regions the electricity production will temporarily exceed the demand and the secure and o ptimum operation of the power supply systems can be endangered.
