$2200000000/392000000W = $5.61/W. Ouch, but if you have the money that's of no concern. I wonder what the balance would have been verses a PV set up? The birds would have been better off at least ;) Still, "clean" (why say green?) energy is still a lower cost than burning stuff.

Essentially you've shown that it cost around $5600 per kW, which is expensive for a power plant but not unreasonably so. The value comes in that there's no fuel to burn. It's like building a dam, but without the concerns over fisheries. Now if we can just loft a solar reflector in geo-stationary orbit so that it produces at night, its productive capacity will increase by at least double, if not more (accounting for losses for when the sun's up, but the angle is too low).

Wouldn't that be $5.61/W *this year? Then $2.80/W next year (+operating costs) $1.87/W (+ operating costs) the year after ... and so on.

On the type of power plants I work on (DO and HFO), fuel represent 70 to 90% of the life cost... Short term calculations are pretty blind to facts.

This solar plant might be the last of its kind. Prices of photovoltaic cells have fallen so much it is not feasible to build csp thermal plants anymore.

There should be a significant amount of shelter and shade created UNDER the mirrors, so I predict that some local wildlife will benefit greatly and others not so much.
You win on the roundabouts, you lose on the swings.
How do they keep the mirrors clean?

Given that solar is now $1/W, this would not appear viable on face value.
But it doesn't add up in my mind. In reality as with any 'different' project, all the costs were bloated to hell, and every man and his dog made money on it, as usual. And big oil as usual is smiling in the background.
A solar concentrator is essentially a steam engine on its side, with mirrors focussing the sun on its boiler. As such it should cost no more then the land, labour, iron and fabrication of the materials. The whole thing can be made modular for cheap overseas and imported.
If people were serious (and there was no influence in the background to keep status quo) these things would be peppered all over the place and costs would be around the $.5-1/W
If they really wanted to double wammy it they would combine the concentrating mirrors with lower efficiency solar panels, which would work in a roundabout way because the head would reflect back some of the light, which would get picked up by the panels a second time.

Around $5500 per kw, vs around $1500-$2500 per kw for a brand new coal-fired power station-& between $2500-$3500 per kw for a brand new gas-fired power station. That's not too bad, especially when you consider that this price will come down as more such facilities get built (material costs in particular). Also, as JD rightly points out, that price differential will level out quickly given the lack of ongoing fuel cost & waste disposal costs (millions of tonnes of fly-ash waste are produced every year by coal-fired power stations, waste that needs to be disposed of, safely, as its usually laced with heavy metals & even radioactive materials). I am curious, though, as to whether they did the smart thing & installed salt storage tanks, as molten salt would allow this sucker to run 24/7, for a few days, without any additional sunlight.

This facility would be no greater threat to bird populations than a single high-rise building.

What ever happened to using sodium as the heat medium instead of steam? Sodium can store enough energy on a sunny day to also radiate it back through the night.
