| + | ====== Hydro dam cost ====== | ||
| + | The hydro dam cost consists of the costs of the following elements: | ||
| + | * [[#Existing and New plants|Existing plants]] | ||
| + | * [[# | ||
| + | * [[#Dam height increase|Dam height increases]] | ||
| + | * [[#Existing and New plants|New plants]] | ||
| + | |||
| + | It has been assumed that the existing 8.1 GW will always be used. Renovations, | ||
| + | |||
| + | ^Electricity production increase potential (2050 compared to 2011) [GWh] ^^ | ||
| + | |Dam height increase|330 | | ||
| + | |Renovation |462.5 | | ||
| + | |New plants |107.5 | | ||
| + | |**Total** |**900** | | ||
| + | |||
| + | The use ($PotUse_i$) of the above listed potentials depends on the [[hydro_dam|hydro dam]] slider as in the following equation, | ||
| + | |||
| + | $PotUse_i = Pot_i * \displaystyle \frac{8.2 - Slider}{8.2 - 1}$ | ||
| + | |||
| + | where $Pot_i$ is the one of the electricity production increase potentials and $Slider$ is the [[hydro_dam|Hydro dam]] slider value that is defined between 8.1 and 8.2 GW. | ||
| + | |||
| + | ==== Renovation ==== | ||
| + | The extra capacity related to renovation is calculated from the electricity production increase, assuming a capacity factor of 0.244. Its specific investment cost is 3'239 CHF/ | ||
| + | |||
| + | ==== Dam height increase ==== | ||
| + | The fact on increasing the height of the dams has two effects: | ||
| + | |||
| + | * Additional electricity production (as the potential energy is higher) = 330 GWh | ||
| + | * The possibility to transfer electricity production from summer to winter. The higher storage capacity gives the option to turbine less water during summer, saving it for winter. It is has been estimated that the electricity production that can be moved from summer to winter can reach 2'400 GWh < | ||
| + | |||
| + | ==== Existing and New plants ==== | ||
| + | The extra capacity related to new plants is calculated from the electricity production increase, assuming a capacity factor of 0.244. | ||
