Texas A&M CT Announces $600M USD Solar Test Farm, First Univ. to go All Solar

A hundred manufacturers and technology-makers will field products
Texas A&M Univ.
this week a pretty clever way to save on its power costs -- turn nearby unused acreage into the world's largest solar test farm, dubbed the "Center For Solar Energy".
(Note: There are many bigger
farms, but Texas A&M is billing this as the biggest farm purely for solar prototyping/R&D.)
Texas A&M System Chancellor John Sharp
and A&M-Central Texas President Marc Nigliazzo, the new farm will be far different from commercial farms, fielding hundreds of solar cell designs from dozens of manufacturers. Mr. Sharp said he hopes to have over 100 manufacturers and solar technology players onboard for the project, which he thinks could draw in $400-500B USD in research over a five- to six-year span.
Why does the university claim that much investment will be inbound? It's confident that by making itself the nucleus of all things solar, it will become the favored prooving ground for all manner of technologies that produce power from sunlight from
to more novel designs
like stirling engines
. It says that a product that would take six years to develop elsewhere should be able to be fully tested in only two years, thanks to this concentration of expertise.

The farm will be situated on 800 acres in Bell County, and is expected to produce 50 MW. That's enough to provide 100 percent of the university's power (with grid storage smoothing periods of low production), plus enough juice for 20,000 nearby homes. The installation will also provide electricity to the nearby

largest active-duty armored post
in the U.S. Armed Services. Fort Hood officials were on hand at the project kickoff.
A&M Chancellor Sharp
, "Obama has charged military installations to use 30 to 40 percent of renewable energy on their bases. With this [center], Fort Hood thinks it will be the first post to achieve that."
The project will cost $600M USD, but most of the costs will be absorbed by venture capitalists, eager to profit off the technologies tested and developed at the site. As a result, the university says it does not expect to "expend any capital on the project", and in fact expects to save "$250,000 in its first year of center operation."

Students at the university will also gain new options -- "physics and business degrees with an emphasis in renewable energy; and advanced degrees in those same disciplines" will be offered.
So far the primary private-sector collaborator is California-based

, a renewable energy consulting firm.

None of these alternative energy sources are competitive with current natural gas. Although there may be special small cases like this one, the vast majority of the power market isn't going away.
Fresh water is not required for natural gas turbine power plants. You can get some efficiency improvement with wet cooling over dry cooling but it's not required.

That's simply wrong. It is true that in general natural gas is cheaper in a larger number of regions, but the number of regions where renewables are better is growing every quarter, and it's growing quickly.
This is what solar expansion in Germany looked like. Watch how it grows, because that is currently happening in southern California and Arizona.

Solar's capacity factor in Germany absolutely sucks. It's less than 0.1. That is, if you have 500 MW of solar panels installed, on average they will produce less than 50 MW. By comparison, the average for solar in the U.S. is about 0.145, and up to 0.185 in the desert southwest. Onshore wind's capacity factor is about 0.2-0.25, offshore wind about 0.3-0.4, hydro about 0.4, coal 0.6-0.7, and nuclear 0.9. If you want to compare installation sizes for different power plants, you need to divide by this capacity factor. e.g. If Germany shuts down a 1 GW nuclear reactor hoping to replace it with solar, they'd have to install 9 GW of solar to generate the same amount of electricity.
Except in specialized (off-grid) applications, solar in Germany is just plain. The
reason Germany is using solar is because of politics. Their attempt to block nuclear while expanding renewables has cause them to burn more coal to take up the slack, resulting in an
in greenhouse gas emissions.
On a cost per kWh generated over the lifetime of the plant, solar is currently about 2-4x more expensive than the alternatives. Wind is about the same as to 1.5x more expensive. So yes there are places where wind makes sense. There are almost no places where solar makes sense, even in the desert. About the only place it's cost-effective is in off-grid applications, and remote areas where electricity is very expensive. e.g. some of the smaller Hawaiian islands where it can be over $0.40 per kWh, vs a national average of $0.12 per kWh. (For comparison, electricity in Germany is around $0.32 per kWh, largely due to the renewable initiatives.)
That said, it sounds like what Texas A&M is trying to do here is attract $600 million in R&D funding for solar. They're not trying to build a commercially viable $600M PV solar farm, they're trying to attract research into solar technology. I don't see any problem with that.
