@GettingCooked @Bunnyslope @Johncdvorak Not exactly. The blades connected to the hub can turn as soon as they are properly installed. Generally when we install the hub and blades, they are locked until many other stages are complete. But the turbine does not require power for the blades to spin, or to start them turning. There may be models of turbine I am not familiar with that do it way, but I have never seen or heard of them.

@GettingCooked @Bunnyslope @Johncdvorak The hub and blades are so wind efficient as I stated earlier that they can capture and turn on a breeze you cannot even feel. They will however run optimally when the power is applied and the computers that control the pitch of the blades starts to tweak them for the prevailing conditions.

@GettingCooked @Bunnyslope @Johncdvorak Yup and I have heard Senators like Malcolm Roberts and Gareth Rennick in Australia saying the same things. Its not true of the turbines I have had experience with and that is the 3 major brands. Vestas, Goldwind and Suzlon/Repower.

@Bunnyslope @GettingCooked @Johncdvorak I get triggered by the details. This topic particularly I have had people screaming at me with these same myths, the whole time I was in the industry. We had a model with an electronic "kiosk" at the base of the tower. Locals managed to convince themselves they were diesel generators that kept the turbine spinning when there was no wind. Le sigh...

@Bunnyslope @GettingCooked @Johncdvorak The diesel generator thing is also from a kernel of truth though. When we finish a top build and need to adjust parts that require power to manipulate, such as the pitch of the facing of the hub, before the turbine is connected to the farm grid, we use big generators to power up those parts and adjust them as required. So one of the first things we do is face the hub in a direction that make is easier for us to align the crane for fitting the blades.

@ringo @GettingCooked @Bunnyslope @Johncdvorak Yes that is pretty accurate. There are computer controlled servo motors that handle the pitch of the blades to have them optimally catch the wind second by second. At first we use a generator to power these systems and test them. Once the turbine is commissioned (certified as ready to go) it is locked up and we move on to build the next one. Eventually when the high voltage cables are all done, it gets hooked to grid. Usually the very last phase.

@ringo @GettingCooked @Bunnyslope @Johncdvorak I say "usually" because depending on the build order of each turbine and how the electricians are progressing getting the grid in place, we may energize one part of the farm, while other parts are still under construction. Or a turbine may be individually hooked up for testing purposes to ensure we are getting the ones down the line correct.

@GettingCooked @Bunnyslope @Johncdvorak This was the "boots on the ground" I sent a few months ago, right on JC's birthday. I am happy to repeat the numbers, but it would take too many posts so I put it in a PDF, I would just have to find it on my laptop lol. In short "hosed" is not the word. The MW return on investment is beyond pathetic. Musselroe Windfarm for example 300ish Million for effectively about 20MW of power. The math is not complicated but I am long winded in explaining it.

@GettingCooked @Bunnyslope @Johncdvorak So the last couple of windfarms I worked on used 3MW turbines with a height of around 110m. They can generate in very light winds, but have an optimal wind speed of about 7-8m/s (from memory) but will generate from about 3m/s to about 25m/s when the computers will start to shut down to save the machinery. I always argued that they should be combining windfarms with staged height dams. Pump the water up, then hydro power it out. Inefficient, but also not.

@GettingCooked @Bunnyslope @Johncdvorak In Australia the grid is about 10GWH hours oversupplied. So using excess wind and solar, of which there is a LOT! to pump water up to elevations, then letting it gravity down pipes through a hydro turbine would be like making giant batteries. The engineering inefficiency of pumping up then running out is an argument, but the alternative is wind and solar being built, then not being used at all. Which is the current status quo.

Ok see if this works. This is a document I made explaining the average cost vs power supplied for an "average" windfarm. Using a specific example of a farm I worked on. https://file.io/0OhmIzB3fH8C

This is a document I made using a real world example of a windfarm I worked on. It breaks down the costs vs energy generation. It would apply pretty accurately to any windfarm.https://easyupload.io/osbvn8

@Sophistifunk @GettingCooked @Bunnyslope @Johncdvorak Exactly, the subsidies are so enormous that the construction shareholders basically get a free windfarm, that they then get to sell to whoever they like. All funded by the tax payer. The average Windfarm job is subsidiesed to the tune of about 90k per employee also.

@Sophistifunk @GettingCooked @Bunnyslope @Johncdvorak The wholesale power price is the price all the ABC types use to argue that power prices are falling with more renewables. But the wholesale price is of little interest to the consumer. The retail price continues to go up and all that is caused by is greed.

@GettingCooked @bucksnort Um not really without knowing more. I will read the stuff and see what I can glean. Lots of moving parts here.
