Spain overtakes U.S. in solar power with La Florida plant

By | July 15, 2010, 12:19 PM PDT

With the opening of the “world’s largest solar power station,” Spain has overtaken the United States as the biggest solar power generator in the world, according to a new report.

SAMCA’s new La Florida parabolic trough solar plant in Alvarado, Badajoz brings Spain’s national solar output to 432 megawatts, exceeding America’s national total of 422 megawatts, reports The Guardian.

(Author’s note: As several educated readers have commented below, the Guardian report is both unclear and incorrect. According to Smithsonian magazine, Spain currently produces about 3.65 gigawatts of solar power, second in the world after Germany. Solar power in Spain represents about 3 percent of the nation’s total power. To compare, the U.S. generates less than 1 percent of its energy from solar power. Spain’s solar output is expected to grow to seven gigawatts in the next three years.)

Parabolic trough solar is distinguished by the use of a parabolic mirror that redirects light at a tube filled with liquid, which heats to produce steam power that runs turbines to produce electricity. The mirror rotates over the course of the day to compensate for the sun’s movement through the sky.

The La Florida solar farm covers 550,000 square meters (about 77 soccer fields, The Guardian says) and has a capacity of 50 megawatts. It’s rated to produce 175,000 megawatt-hours per year of power.

To compare, customers of the Consolidated Edison Company of New York — the dominant utility in the city — used 62,062 gigawatt-hours of electricity in 2008.

What’s more, another 600 megawatts of capacity are slated to come online within the year, according to solar energy association Protermosolar.

The Guardian notes that Spain’s total solar power production is now equivalent to the output of one nuclear power station.

Spain, like other European nations such as Germany, has excelled at deploying renewable energy projects thanks to large subsidies for the technologies.

A few facts about Spain’s renewable energy industry from the report:

  • It’s the third-largest producer of hydro power behind China and the U.S.
  • Spain’s wind farms produce about 20,000 megawatts of electricity.
  • Spain receives 340 days of sunshine a year, on average.
  • Last year, solar energy met 2.8 percent of demand in Spain.
  • Spain’s renewable mix is currently 12.9 percent.
  • In March, the government announced a target of 22.7 percent renewables by 2020.
  • Spain is now the fourth largest manufacturer of solar power technology in the world.

Great Going, Spain!
12.9% renewable - my word!

RE: Spain overtakes U.S. in solar power with La Florida plant
I am disappointed in the reliability and quality of your information. 50 Megawatts is definitely not enough power to supply New York City. And if you are talking about daily use, you have to specify the correct units, ie megawatt hours. Megawatts is for rate or capacity. Is the 20,000 MW you claim for Spain the capacity of its wind farms or an average production rate? These are two very different measures. Spain is not the third biggest producer of Hydro power. Hydro means water, and Spain isn't even in the top 10 of hydro-electricity generators. (China, Canada, Brazil, US, Russia.....). If you use 'Hydro' when you mean "non-fossil fueled' or 'nonconventional' you are confusing the reader. And a typical commercial nuclear power reactor is 1000 MW, and many plants have more than one reactor, therefore the Guardian's assertion that Spain's total solar power production (at 432 MW) is equivalent to one nuclear plant is patently wrong, not even mentioning that the nuke runs through the night. A 1000 MW nuke produces 24,000 MW-hrs in a day, whereas the 432 MW solar total will produce roughly 432x8hrs = 3500 MW-hrs in a day, ie, an order of magnitude less. C'mon guys, let's exercise some basic math and prudent skepticism before we paste superficial information from the main stream media into this site.

Excuse-me, but 550,000 square meters is equal to 5,918,000
square feet, since 1 square meter = 10.76 sq ft.

"not even mentioning that the nuke runs through the night. "

You also didn't mention that modern Concentrating Solar plants
using molten salt, ALSO run all night.

Molten salt can store a week's worth of power before cooling off.

@jkirk3279
Yes, the molten salt approach can potentially address the problem of continuous production of power through non-sunshine hours, but it doesn't in this case. If you check you will see that the actual storage capacity is less than 8 hours. Furthermore, there is the inconsistency in the expression of power capacity between these systems. A 1000 MW nuke produces 1000 MW of electricity 24/7. This project is claimed to be a 50 MW producer, but then you find that its annual production is estimated to be 175,000 MW-hr/year which works out to 20 MW average.

@gstreb54 @FuzzyIce
Both of you are correct -- The Guardian report is wrong, and I
compounded the problem by reprinting their figures without
vetting them and worse, offered statistics for context that were
incorrectly calculated.

I sincerely apologize for the errors.

I've taken care to review this post and have made the following
changes:

1.) Included vetted figures for Spain's total national solar output,
as well as context with regard to the U.S.

2.) Made a clear distinction between power capacity and power
use, and offered new, relevant comparisons for context.

4.) Added an author's note in the post explaining the changes.

Find anything that's still amiss? Please send me an e-mail, and I'll
be sure to correct it.

@Andrew
Good of you to follow up with corrections. I note the reference to "hydro" persists, when I think "non-fossil fueled thermal" is meant.
Interesting to compare the La Florida production to Con Ed's sales to NYC customers. It would take 355 La Florida's (plus appropriate power storage for demand balancing) to supply New York City.
