To bask Ranking – and wind energy in Switzerland is lagging behind in the case of green electricity, why Switzerland performs in comparison to EU countries and what the others are doing better.Martin Läubli112 Kommentare112Die Umwelt Arena in Spreitenbach is generated with the building-integrated Photovoltaic 40 percent more energy than it needs.Image: Alex Buschor

Actually, Switzerland has the best conditions for a climate-friendly energy supply with renewable energy. Storage and run-of-river power plants, almost 60 percent of the electricity production. And in the meantime, it is undisputed that Solar and wind power have the potential to replace the nuclear power. “The PV and the Swiss hydropower would complement each other in the Winter, perfect,” said Urs Muntwyler, by the Bern universities of applied Sciences on request.

Still, the source of new renewable energy gushes out in international comparison is still sparse, such as the today study published by the Swiss energy Foundation (SES) shows. Only five EU States are worse than Switzerland. The SES published a comparison, since 2010, these countries, and notes that our country has ranked since then, always in the rear seats. Wind and solar plants produce far less electricity than the neighbouring countries, even in countries in the North of Switzerland, like the Netherlands and Belgium, the solar energy is higher in the course.

The Figures of the SES study are related to the Per capita production, the share of total electricity production, as well as the development in the last few years. The share of PV on total electricity consumption in Switzerland is about 4 percent, and that of wind power is 0.3 percent. The SES members of the house and especially in your study of Austria is a landlocked country and with similar topographic conditions presents. There was a good 11 percent of the electricity demand is covered by wind power. The PV is also progressing, however, as in Switzerland, just slow.

Also when different estimates are partly far, the Federal office for energy assumes that PV on roofs and facades have the Potential to deliver more electricity than currently per year is in demand. Solar and wind power, however, must compensate not only the gradual phase-out of nuclear power, but also the more necessary, when gasoline and diesel cars are replaced by electric vehicles and Oil-fired heating systems by heat pumps.

However, such as Solar and wind power, and biomass, such as wood – fired power plants should be promoted more? The Revision of the energy law, which was sent by the Federal Council at the beginning of April in the consultation process to parties and organizations, is intended to give the power industry more certainty in planning. Because the funding measures for the Expansion of renewable energies expire at the end of 2022, and the end of 2030.

gross assets

the absence of It is missing, according to various energy experts, primarily on large power plants in Switzerland. The energy producers are now unsettled, whether it’s worth it at all to invest in such projects. A study of the Association energy future of Switzerland shows that Swiss energy supplier is investing, and investors in, foreign, renewable power plants, which annually produce about 11.5 terawatt-hours of electricity. This corresponds approximately to the domestic amount of electricity from renewable energy sources (excluding hydropower), which is set in the current energy act as the target for 2035.

This target is to increase this massively. “If we want to achieve by 2050 net-Zero greenhouse gas emissions, we must accelerate the Expansion massive,” says Felix Nipkow from the energy Foundation. So to deliver up to 2035, especially solar power and wind energy 35 -45 terawatt-hours of electricity. That would be about half of the electricity needs to renewable energy, which would be in accordance with the models necessary to get out of the nuclear energy and the fossil age to get out.

the EU as a model

in order To implement this, the SES is strong in the European Union, the essere with its financing policy, the investment security for investors as a verb. “The current market, no collateral or more,” said Nipkow. Already today, there are days where a kilowatt-hour of electricity at the stock exchange practically has no value anymore, as soon as Europe-wide with enormous Solar and wind power productions lead to an Oversupply. This Situation will increase further if the share of these sources of electricity continues to rise. Many EU countries therefore provide minimal remuneration for new power plants to these price fluctuations.

the Alliance of the Swiss energy economy , which consists of the large energy supply companies, municipal utilities, and various industry associations, participates in your solution proposal, the EU as a model. You want in addition to the Expansion of small-scale systems to be supported in the revised energy law through investment contributions, to introduce a so-called sliding market premium for large installations. Of projects, which have in the case of periodic invitations to tender of the lowest energy prices would benefit. The decrease in prices in the electricity market under which the price bid, will pay the producer the difference. The market prices above, will be paid no premium. This System should be ensured about 20 to 25 years.

energy producers will only invest in Switzerland, if you see collateral, to the extent that the market premium is an insurance premium.”

Gianni Operto, President of the umbrella organization of the economy for renewable energy and energy efficiency AEE

The proposal of the Federal Council for the Revision of the energy act does not provide such a reward system, however. He sees in the investment contributions is a great incentive to encourage energy producers to invest in renewable energy. He finds support through the energy company BKW, which supports not only a large energy producer, Allianz. Investment contributions to be considered as start-up funding during a transition phase. For fixed purchase prices. For Gianni Operto, President of the umbrella organization of the economy for renewable energy and energy efficiency AEE, are the premiums, however, not subsidies but a market-based Instrument. “We need in the future, a lot of domestic electricity, energy producers, however, are only investing in Switzerland, when you see collateral, to the extent that the market premium is an insurance premium.” When the tenders finally, only the project will get the award, which is the most cost-effective electricity supply do. This would motivate the “losers” to improve.
