It has been assumed that the actual 3.8 GW will always be used. The cost for this existing capacity is based in the next data.
The first step to calculate the cost of the new capacity is to study how is the new electricity production going to be obtained. It is estimated that in 2050 the extra electricity production from Run-of-river can amount to 3'600 GWh. This value do not include the reduction due to the effect of LEaux. The next table has been created with the information from PROGNOS(2012) and OFEN(2012).
|Potential increase in electricity production (2050 compared to 2011) [GWh]|
|New small hydro (<10 MWe)||1'600|
|New big hydro||1'323.5|
A capacity factor of 0.507 has been assumed for obtaining the power capacities from the previous table. The obtained power and the data/assumptions presented in the next lines allow to calculate the cost linked to the new electricity production.
|Specific investment [CHF2010/kWe] |
The cost for the extra capacity obtained through renovation is 5'224 CHF/kWe . No O&M cost is considered as this cost is already accounted in the existing facilities.
The cost is based on the data for the already existing facilities.
