 +====== Electricity grid cost ======
 +The replacement cost of the Swiss electricity grid is 60 billions CHF <sup>[[#References|[1]]]</sup> and its life time is 80 years <sup>[[#References|[2]]]</sup>.
 +
 +The electricity grid will need additional investment depending on the penetration level of the decentralized and stochastic electricity production technologies. AES(2012) <sup>[[#References|[1]]]</sup> presents three scenarios with different percentages of renewable energy sources with their consequent different development costs for the electricity grid.

 +^  Total investment for electricity grid development [billion CHF]  ^^^^
 +^ ^  2011-2050  ^^^
 +^ ^Scenario 1^Scenario 2^Scenario 3^
 +^High voltage grid |2.6 |2.6 |2.6 |
 +^Medium&Low voltage grid |2.4 |5.5 |9.6 |
 +
 +For choosing the scenario, the calculator compares the percentages of PV and Wind in the electricity mix of the three scenarios with the electricity mix of the calculator.
