Are you actually without nuclear power? For Switzerland, this question must be answered with Yes. Because of the energy strategy 2050, which sanctioned the electorate of 2017 is not a choice. The construction of new nuclear power plants is prohibited and the youngest of the four NUCLEAR power plant is 2019 already 35 years old.

The energy strategy is that renewable energies are promoted – such as Wind or solar energy. To fear, even without nuclear energy, no Blackouts. Also the dependence from abroad and possibly from foreign nuclear power should not be larger.

What to replace?

In the past year, the electricity consumption decreased mainly due to the warm weather, as the latest Figures from the Federal office for energy. 2018 Switzerland spent 57.6 billion kilowatt-hours (kWh). To do this, 4.3 billion kWh, the received Transmit and Distribute lost. The efficiency of the energy objectives, strategy, the power consumption decreases further in the future, 13 per cent below the level of 2000.

The total production amounted to 67.5 billion kWh of consumption. It is not surprising, therefore, that Switzerland imported 2018 net exported as. Tend to higher imports in the Winter, because the water power plants generate less electricity. However, between Switzerland and abroad, a permanent reigns of Give and Take. What is being produced at current, it flows into the European electricity network, of which Switzerland is a part.

hydropower contributes 55.4 percent to electricity production in the case of

in 2018, nuclear power plants, 36.1 percent, or 24.4 billion kWh for the power production contributed to this. Renewable energies significantly below ten percent. The share of solar energy was in Switzerland on a 2.75 percent. While hydropower contributed with 55.4 percent of the largest part. Currently we cannot do without nuclear power.

in 2017, fell to 3.7 billion kWh of renewable energy. This production would have to be sixfold, to replace nuclear power.

The plants would have to be built with Overcapacity, because the Wind is blowing and the sun does not seem to be constant. For the compensation in case of production fluctuations about pumped storage to provide power plants.

whence comes the money?

The electricity consumers will pay the net award for the promotion of renewable energies. Currently this is a maximum of 2.3 cents/kWh. Annually well over a billion Swiss francs in funding. But how far these means ranged?

According to Simon Banholzer, an expert on nuclear energy and the Swiss energy Foundation, would be the cost of the replacement of a NUCLEAR power plant by the PV installations to around seven billion francs. At least part of this could be with subsidies.

The focus on PV is economically the most sense, says Banholzer. You would align the power of a surcharge on solar installations, would be the domestic replacement of all nuclear power plants for eight years, within the ensured and paid for, he is expecting to. So fast it needs to go, because the soon-to 35-year-old nuclear power plant in Leibstadt about is likely to remain significantly longer on the network.

No Problem is the potential of solar power. As the Federal office for energy announced this week is the solar power potential of facades and roofs of the 40 times the current production. On the website of the sun roof.ch can be checked for Swiss locations, as well, with the roofs and facades for a PV system and is also financially worthwhile.

energy companies are investing abroad

Today, Private investing, primarily, the facilities at home to install, or company such as SBB and the Migros, the company’s building to use for the production of electricity from solar power. Also, energy companies and nuclear power plant operators such as Alpiq, Axpo and BKW invest In the country and abroad in wind farms and solar power plants. So, Axpo announced on Thursday, to a Photovoltaic-manufacturers and operators from France.

conclusion: The potential seems to be the smallest Problem of Switzerland. The major hurdles are the readiness and costs. For Axpo it is because of the conditions and at the price as it goes on. “As long as the price of Electricity is low, not worth investing in new large-scale installations,” says Axpo spokesman Antonio Sommavilla. After all, the price of Electricity has recently attracted something.
