In Norway and Sweden the build<strong>in</strong>g of pumped storage power plants has so far not<br />

been economically profitable, s<strong>in</strong>ce these countries have many conventional storage<br />

hydropower plants, which effectively take care of all power system service needs.<br />

While pumped storage power plant <strong>in</strong> the traditional sense does not exist, a few<br />

Norwegian hydropower plants are used once a year dur<strong>in</strong>g the wet season to pump<br />

excess water <strong>in</strong>to higher located reservoirs. This maximises the long-term storage<br />

capacity and <strong>in</strong>creases flexible power generation.<br />

2.2. Rema<strong>in</strong><strong>in</strong>g hydropower potential <strong>in</strong> <strong>Europe</strong> over 650 TWh a year<br />

Although most of the best sites for hydropower plants have already been developed <strong>in</strong><br />

<strong>Europe</strong>, at present only about half of its technically feasible potential 12 has been<br />

developed for EURELECTRIC <strong>Europe</strong> and only about one third <strong>in</strong> the non-EU member<br />

states. 13 There is thus additional potential of 600 TWh a year <strong>in</strong> EURELECTRIC <strong>Europe</strong><br />

The technically feasible hydropower potential per year is def<strong>in</strong>ed as the total hydropower generation potential of<br />

all sites that could be developed with<strong>in</strong> the limits of the current technology regardless of economic or other<br />

considerations such as regulatory constra<strong>in</strong>ts or environmental preferences. For this report, the technical<br />

potential is used as a reference, as the economic potential fluctuates accord<strong>in</strong>g to oil and gas prices and special<br />
