The real cost of wind power is much higher

the wind Industry has, through a wise approach reduced its costs to a level which makes the new wind power the cheapest way to bring new electricity generation in Sweden. As long as there is capacity in the reservoirs in order to balance the variation in wind power production, it is therefore appropriate to build new wind power.

however, There are several technical limitations to how much wind power as is reasonable to produce in a power system. One is the absence of inertia. Another is the capacity of water reservoirs. Exceeds these limits, the investment required in the inertia, transmission and efterfrågeflexibilitet.

Our colleagues at Halmstad University, argues in his op-ed that the new wind power is cheaper than new nuclear power and that nuclear power's carbon footprint is significantly larger than the wind power. The latter statement is incorrect, and the last is only true as long as the wind is not burdened with the costs of inertia and its non-planerbara character.

Looking closer, you see that Hylander and Sidén's ”scientific” values are based on scenarios where uranium is mined out of the unusual lågvärda deposits (120 grams of carbon dioxide/kWh), and that the enrichment is done with the energy-intensive gaseous diffusion driven by fossil power generation (80 grams of carbon/kWh). The day is broken, no deposits of so low uranhalt, and there are no gasdiffusionsanläggningar in commercial operation. The life cycle analysis made for the Swedish nuclear power based on uranium is purchased from Canada, which gives a carbon footprint lower than the 10 grams/kWh.

the Cost of new wind power in Sweden can be estimated from the data as the Swedish energy agency and Swedish Wind energy publishes. In Sweden, the investment cost for new wind power 15 million per Megawatt, and the running cost on average of 15 ¢ /kWh. The weighted cost of capital for Swedish power generation was 5.7 per cent, and the availability of Swedish wind power generation in an average of 30 per cent. We assume that the average life expectancy of a new wind turbine is 25 years, is the production cost of 58 ¢ /kWh, the same level as the Skellefte force set for new wind power in Sweden 2018.

. Sweco estimates these costs to sek 290 billion in a scenario where the 29 GW of renewable capacity is introduced to replace the 9 GW kärnkraftskapacitet. The specific cost is charged to the investment in renewable capacity is thus 10 million per MW, giving a total cost of 87 öre/kWh.

We can do the same analysis for replacing the old Swedish nuclear power with new. With a konstruktionskostnad of 62 million sek/MW, an operating cost of 17 ¢ /kWh (Forsmark annual report 2017), a weighted cost of capital of 5.7% and an amortization schedule of 30 years, will be elproduktionskostnaden 70 öre/kWh. This figure is significantly lower than the cost of new nuclear electricity in britain, where EdF has a weighted cost of capital of 8.9%.

at the same time is investeringsriken for new nuclear power plants and high. Therefore, it is important to correctly analyse and report on the costs that accrue due to the non-existent inertia and non-planerbara character, at each decision to invest in new electricity generation.
