Key Factors for SHP Potential
Factor Fact
Capacity installed in 2000 in GW 32 GW**
Potential in 2010 in GW 45 GW
Future potential beyond term year given medium-high
Rule of thumb for conversion ratio*
(installed power to electric output)
1 kW --> 3,500 – 6,000 kWh per year
* Mean value based on European average for the lower rate (30 TWh production and 9 GW capacity in 1995), and
the average of selected European countries (12 TWh production and 2 GW capacity in 2000) for the higher rate.
** Higher and different capacity figures are communicated based on different SHP definitions.
