'No More Wind.' WA state utility questions efficacy of wind farms for power generation Bill Virgin 2020 Sep 19 The News Tribune amp.thenewstribune.com/news/business/biz-columns-blogs/article245808810.htmlHere in the Pacific Northwest the winds are strongest in the spring, just when the hydro dams have excess water for the turbines. Wind power is a poor match to the needs of the region.

...wind power generates half of UK’s electricity Except that it's a barefaced lie. A lie, characteristic of renewables' PR machine. To maintain the endless flow of public funding, the renewables industry relies on the public being continuously flooded with the illusion that renewables could supply all of their power needs. It is sites like BNC that should be as continuously calling them out as liars. If the axe grinder who wrote that headline for powerengineeringint.com were brought to court, they would certainly claim that the misleading was purely accidental and they were merely drawing to our attention to a freak occurrence between 1130 and 1200 on October 26. But it was no accident, they were skilfully using the event to maintain the illusion. We should not be party to it by repeating the lie. You and I know that there is no way that renewables could provide half of UK's average electricity, let alone all of it. Wind, by itself, has a capacity factor of about 30% and solar has much less in those latitudes. Far from being second, fossil gas is the main supplier of electricity in the UK, and will continue to control hearts and minds there until the case for exterminating fossil fuels overwhelms antinuclear sentiment.

...wind power generates half of UK’s electricity Except that it's a barefaced lie. … On the contrary, the article makes clear that this is a peak statistic for a half-hour. The capacity factor for wind power is irrelevant in determining the delivered power for each half-hour interval and the source of the power over that time. The only reason to include this article as worth linking was to indicate that the UK is progressing in the right direction, as opposed to possibly Germany just now.

Come on, admit it. When you wrote those words, you were under the impression that wind had become the first supplier of power in the UK. The slick language of the axe grinder had confused you, however momentarily. That's what they are paid to do. In a small grid powered solely by wind backed by gas, only 30% of the annual electricity consumption would have been generated by wind, because wind only has 30% capacity factor. Most of the annual power, 70% of it, has to be generated by the backup gas. To ensure maximum generation by wind, the gas backup would be open cycle gas turbines. Being only 70% as gas-efficient as the more sluggish closed cycle turbines, there is no gas saving due to wind. So even though the faithful are solemnly reassured that we are on our way to 100% renewables, they are lying – it is gas that increasingly dominates. The deceit has been most successful in Germany. A majority of the voters has been dazzled into believing that Germany is now powered by 100% renewables. Or almost. But now they have woken up to the fact that the entire German economy is beholden to Russian gas. The axe grinders must be proud of themselves. We should have nothing to do with them.

… In a small grid powered solely by wind backed by gas, only 30% of the annual electricity consumption would have been generated by wind, because wind only has 30% capacity factor. … This is false. First of all, the capacity factor cannot exceed the availability factor. If when available the generator is actually used to power the grid then the capacity factor is equal to the availability factor. On most grids most of the time the two factors are equal for nuclear power and under must-take rules, for wind generation. But these figures apply generating plant by generating plant, not to an entire grid. As a hypothetical example, the isolated islands of North Southia either have suitable winds blowing in the north half the time or else suitable winds blowing in the south. The wind turbines in either location therefore have availability factors of 50%. But there is a north-south intertie so that with enough wind turbines the entire grid is 100% powered by the wind farms, half the time from the north and the other half from the south. Now Britain is not a small grid, not with a first world population of 67.8 million. So for even half an hour to power half the grid requirement implies a lot of wind farms, both on and off shore. Incidentally, the reporters at Power Engineering International only wrote up what the British grid operator told everybody in a press release.
