Wind in Texas only 8.7% reliable

Press release, March 29, 2007 -- ERCOT Response to U.S. Rep. Joe Barton:
With regard to renewable energy, ERCOT is proud to have more wind generation in its region than any other state in the nation. Currently, almost 3,000 MW of new wind generation is either under construction or publicly announced, in addition to the 3,000 MW already existing in ERCOT. A significantly larger amount of future wind generation is also under study. Wind energy is good, clean energy and should be used to the fullest of its capability. At the same time, wind does not blow at a constant level, and in Texas is often at a low level at the time of the peak electrical demand during summer afternoons. ERCOT studies the availability of wind generation using its historical wind generation data. Using 2006 data, ERCOT has determined that 8.7% of the installed wind capability can be counted as dependable capacity during the peak demand period for the next year. Conventional generation must be available to provide the remaining capacity needed to meet forecast load and reserve requirements.
(ERCOT [The Electric Reliability Council of Texas] manages the flow of electric power to approximately 20 million Texas customers.)

France's president Sarkozy not impressed by wind turbines

Nikolas Sarkozy, President of France, at the concluding session of the "Grenelle de L'Environnement, Thursday, 25 October 2007 (click here for the full speech, in which he also announced that industrial wind turbine construction should be limited to existing brownfields):

Franchement, quand je survole certains pays européens cela ne donne pas envie.

Francamente, cuando sobrevuelo algunos países europeos, no dan muchas ganas de instalarlos.

Ganz ehrlich, wenn ich über manche europäischen Länder fliege, dann vergeht mir die Lust.

Frankly, when I fly over a number of European countries what I see does not recommend wind energy.

Newsweek adds defamatory voice to wind development juggernaut

Not satisfied with the "NIMBY" pejorative, Roya Wolverson, writing in the Nov. 12, 2007, Newsweek, rolls out "citiot". Taking her cue from professional anti-environmentalist Frank Maisano, spokesman for a coalition of mid-Atlantic wind energy developers, she caricaturizes the battles over industrial wind turbine siting as between farmers and second-home owners ("citiots") -- as if installing an array 400′-high machines that generate noise and visual distraction night and day is no more offensive than spreading manure once or twice a year. Hosting giant wind turbines is no more farming than turning your fields into a NASCAR track.

The caricature, useful as it is to the developers and the landowners salivating for the developers' crumbs, ignores environmentalist opposition, turbines sited on mountain ridges, the fact that as taxpayers we are all paying for the boondoggle, and that, as one of the comments to the article notes, many leasers are absentee owners. As the saying goes, who's watching the farm? She also ignores the common subversion of local democracy, where the leasers are also the town officials that are supposed to listen to all of the people but instead act to self-servingly facilitate the developers.

Finally, she ignores the evidence that wind on the grid does not do what it is supposed to do, that is, reduce the use of other fuels. Small amounts of wind energy -- which is necessarily highly variable and intermittent -- require other sources to work harder to balance the extra fluctuation they add. Substantial wind capacity requires new "conventional" sources to be able to balance it and keep the grid stable. Since the only practical sites for large wind energy installations are far from people (though still impacting animals and plants), they also require new high-capacity transmission lines (not to mention heavy-duty roads) through those remote areas.

What is significant here, therefore, is that the developers (and their abettors) have apparently given up trying to argue that there are benefits from big wind that outweigh the negative impacts. Dare we say, they have lost that argument? They now have only their nasty contempt for opposition voices and appeals to shortsighted greed.

NBC News drinks the Danish wind Koolaid

On Nov. 5, NBC Nightly News, 80% of which is owned by General Electric, the leading U.S. manufacturer of wind turbines, sang the praises of wind energy in Denmark, saying the Danes lead the way that we should follow.

This was part of the network's "green week", a fine idea but one that should not be seen as a license to abandon all veridicality.

The piece on wind included many errors of fact.

To start with, Denmark's wind turbines do not "supply 20% of Denmark's electricity needs".

Denmark's wind turbines produce electricity equivalent to 20% of what the country uses. But much (if not most) of that wind-generated energy is exported to larger grids that can absorb the fluctuations better.

Rather than leading the way to building even more wind turbines, Denmark has in fact essentially halted new onshore construction. Any development that is still talked about (to keep the market for Vestas turbines alive) is far off shore. But even that has stalled since 2004 because of the expense and technical challenges.

The island of Samso is presented as so successfully energy independent that it produces more than it needs. Actually, the island is able to "depend" on its highly variable and intermittent wind turbines precisely because it is still connected to the national grid and not independent at all. The island uses the national grid to balance its wind energy, just as Denmark as a whole uses the international grid.

While it is true that wind turbines emit "no pollution or carbon dioxide" (after their (and their infrastructure's) manufacture, transport, and construction, and not counting ongoing maintenance (including oil changes) or if they are built on and thus disturb peat or other important carbon sinks), the crucial fact is that neither do they reduce pollution or carbon dioxide emitted by other sources. There is no evidence that Denmark has reduced emissions or other fuel use because of wind on its grid.

That is the unfortunate fact that is getting harder every year to deny or ignore, even if one's only goal is to create a market for Vestas and GE.

Dreams of 20% penetration

Carl Levesque of the American Wind Energy Association (AWEA) writes in Renewable Energy Access (Nov. 7, 2007):
AWEA Policy Director Rob Gramlich provided a glimpse of the 20% vision technical report that is due to come out soon. The vision, which Gramlich emphasized assumes "stable and long-term policy," calls for a ramp-up in deployment of wind power capacity form the current 3,000-4,000 megawatts (MW) annually to 16,000 MW per year at peak. Gramlich also showed the conceptual map developed by American Electric Power of a grid that can efficiently accommodate 20% wind (as well as benefit all of the electric industry). The map calls for up to 15,000 miles of new transmission lines.
That's one new giant turbine every hour for the next 25 years (allowing 3 years to get up to that rate). In addition to the proposed 15,000 miles of new high-capacity transmission lines (mostly in rural and wild areas), 400,000 MW of new wind turbines would require 20,000,000 acres (31,250 square miles!) of newly industrialized land.

And since demand will also grow, all those wind turbines will have barely reached 10% "penetration" -- god save us from 20%! And, as well explained elsewhere, they will have done nothing to reduce the consumption of other fuels or their emissions.

Continuing this boondoggle is clearly madness. Enlarging it is sociopathic.

Environmentalists starting to notice destructive wind energy development

The Collectif du 6 octobre notes that they are succeeding in turning environmentalists against industrial wind turbines in rural and wild areas, as evidenced by Nicolas Hulot writing in Le Figaro, October 20, 2007:
Recently, a collective of organizations met in Paris to demonstrate against wind turbines. They often have good reasons. The wind turbine lobby is often cloase to the nuclear lobby, working on mayors of small towns with proposals of new income. They have installed wind turbines in spite of good sense. Fields of wind turbines on industrial farms don't shock anyone. But when magnificent countrysides are sacrificed, I understand why there would be reactions.

Exploding wind turbine transformer

In response to a Nov. 1 query from a concerned citizen for information concerning reports of an explosion in one of the transformers at the "Maple Ridge" wind energy facility on Tug Hill, N.Y., and a truck working in the middle of the night at the base of each turbine, steven_blow@dps.state.ny.us wrote on Nov. 2:
We've checked out the situation and there appears to be no truth to the report.
But janasca@gw.dec.state.ny.us (Jack Nasca) wrote on Nov. 5:
We spoke to the operators at the Maple Ridge site and have learned:

On July 4, a single pad mounted grounding transformer located at the Rector Road substation exploded and was rendered inoperative. This was one of ten such transformers in the substation. No cause was determined, and the transformer has been sent back to the manufacturer for an analysis to identify the cause. Lightning was not a factor. None of the other nine grounding transformers at the substation had any problems, and there have been no incidents at turbine base transformers.

Unrelated to the above, a program of annual preventative maintenance of transformers at the base of the turbines was conducted over the summer. This included an analysis of the mineral oil used as a coolant. A gas analysis of the cooling oil was conducted, which indicated elevated levels of certain gases in about 30% of the transformers, one of which was hydrogen. A contractor specializing in purging gases from transformer cooling oil was hired to remove the gases identified in the analysis. Because the contractor was very busy (apparently this occurs with some regularity with transformers in any type of transmission facility), they worked 24/7 for a 2 ½ week period to complete the task. So at some point they were working at "midnight." The process involves withdrawal of the oil from the transformer, piping it to a truck with the purging equipment, capture and collection of the gas for disposal off-site, and returning the oil to the transformer. It was stated that there is no atmospheric release of gases from this process.
