Master Resource looks at the California Valley Solar Ranch

In a realistic appraisal of the CVSR we should note the following:

· An investment of $1.6 billion 250 MW breaks down to an extravagant $6,400,000 per megawatt.

· The Solar Ranch covers 1,500 acres.

· The CVSR is projected to produce 482,000 MWh per year, implying an operating capacity factor of around 22%.

· Given a reasonable appraisal of the value of 482,000 MWh per year, it is not possible that the solar panels will be able to provide a return sufficient to pay back the $1.6 billion investment within their functional life (not even close), even when ignoring annual operating and maintenance costs. Hundreds of millions of dollars will be lost (see Updated CSVR Cash Flow).

....

A much more viable alternative to a solar generation facility, although not the only one, is a plant using natural gas. A natural gas combined cycle gas turbine (CCGT) facility capable of 250 MW would have required less than one-fourth the capital investment, would be capable of making four times the electricity per year at 88% capacity factor, and would fit on a single acre.

Also, a CCGT facility could have been located closer to the point(s) of actual use of the electricity, and could provide dispatchable energy which could be increased or decreased as demand fluctuates; something the solar facility is incapable of providing.

So why is this project even happening?  Because most of the project was funded by a taxpayer-gauranteed loan.  And then many of the players got direct subsidies and tax breaks.  And finally the electricity from the project gets bought at an above-market subsidized rate.
