I note you are comparing a rather optimistic projection for a version of one future technology (concentrated PV) with a real-world example for a version of another technology in its infacy (off-shore wind).

Still, PV technology is maturing. And spreading. Last year in Germany, it fed about 2 TWh into the grid.

Yes as I mentionned it's "first" of its kind.

The Victoria project FAQ mentions they're building plants to produce needed pieces first so there are still risks.

On the other side the PV cell itself is coming from Spectrolab who has been in the business (for space use in decade length missions) for 50 years and still making progress. The rest is sun tracking mirrors which are not really new either. And if I believe this press release (cited on wikipedia) the CS500 model has been running commercially since 2003 (with a less efficient PV cell but the rest look identical).

BTW I didn't notice but BNP Paribas is also listed as member of the financing team for Jerome wind farm.

Annual power production:     435 GWh

So that's slightly above (3.5%) the 420.5 GWh I computed so it puts the price per installed effective watt at 10.3 USD for wind (vs 10.7).

The thing is, this optimistic price projection reminds me of optimistic price projections for off-shore wind ten years ago, or indeed solar thermal and concentrated solar 15 years ago. They may represent a real potential once the technology is well understood and mass-produced, but I think they wager too much. It's also that this isn't the sole concentrated solar power plant project currently pursued, but seems to claim the lowest price.

On wind, I again emphasize that your example is valid for off-shore wind, which is not much more out of its infacy than concentrated PV. On-shore parks may produce only 60%, but a MW installed costs a third than for Q7.

But, again, these are quibbles, not fundamental doubt in the technology.
