The Ocotillo Wind Farm Keeps limping On

By Roy L Hales

The Ocotillo Wind Farm keeps limping on. According to a recent article in East County Magazine, the site was producing just under 18% of capacity during the first quarter of 2014. As that was the windy season, it seems unlikely that Ocotillo will beat the slightly less than 16% average they set for the first for year of operation (2013). Then there is what the Bureau of Land Management keeps refering to as “general maintenance.”

“It’s very frustrating when we ask about work being done and we don’t get an answer or we get the generic ‘It’s just general maintenance,’” said Jim Pelley. “If they are still repairing these blades it tells me that there is some serious safety issues that we have the right to know about.”

He lives in Ocotillo, California, which is surrounded by turbines on three sides.

The project went online in December 2012 and, since then, crews are said to be working 16 or more turbines during a 24 hour period.

The first gear box was replaced on April 1, 2013 – four months after the project went online.

That day Jim Pelley wrote, “It seems like every day the Siemens workers are working on the turbines. Before these turbines went on line I asked a manager on the project site how much maintenance was required on these Siemens turbines. The answer I got was “These Siemens turbines are the Rolls Royce of the wind turbines and it’s pretty much like you car you have to change the oil once in a while but that’s about it”. Hmm, if I bought a car for $3,000,000.00 dollars and the gear box went out after 4 months of light duty I would not be a happy camper.”

Another gear box was replaced on June 5, 2014.  Ocotillo resident Parke Ewing wrote on his facebook page, “The temperature was 113 degrees today. It was difficult to simply stand and take photos, much less work in this heat. The technicians up in the nacelle were working with hatches open and in direct sunlight. The crane operator had no air conditioning. The ground crew was able to work without mistakes… Hats off to all of you. But, Pattern Energy still sited this project too close to residents… “

One of the project workers responded, “Yes it was, it was pretty Damn windy setting the new gearbox.”

Many of the turbines leak oil. After learning that the reason turbine #87’s gearbox had to be replaced was that the old one was cracked, Parke Ewing questioned whether this might be what is causing all the leaks?

It has been a little over a year since a 173 foot long blade went flying off one of the turbines.

Pelley says they have replaced the blades on nine turbines and the rest have undergone a “root upgrade kit.” This consists of drilling holes in the root of the blade and then fastening it with glue and bolts. (Watch a workman doing one in the video below)

Parke Ewing recently sent me the following description of  what it is like to be surrounded by a Wind Farm:

“As you know living in the middle of this facility has not been easy, in fact it has been and continues to be very upsetting. We are very suspicious of unusual work activity out here, especially anything that could be related to the turbine blades. Since many of the workers have had past experience with a fiberglass and composition company, it is obvious that work is occurring on the turbine blades. Airway Services appears to have up to 8 crews working at night. We can hear sanding and grinding noises coming from the turbines. Are fiberglass particles being released into the air? We believe that tyvek suits are supplied by the Alsco company for the hazardous dust protection of the workers, so we presume that residents can also be exposed to fiberglass dust. Is the BLM or the county aware of this work?

“The oil leaks seem to be continuing not only from the nacelle/tower area, but also from the hub area. We hope that Pattern Energy is accountable for these leaks? When will the leak problems be solved?

“The noise is still a problem, whether it is at or below some decibel level that was predetermined to be within compliance of some standard that the wind industry has deemed acceptable, it is very annoying at times and I am sure that the speed of the turbines, that directly surround my home, could have their parameters modified during these conditions to make less noise. We are now very suspicious that sound recording levels in Ocotillo could have been manipulated prior to the DEIR/FEIR. For example, at a sound receptor test site, a vehicle could have purposely been driven past a recording device to raise the ambient sound levels of that receptor, just enough to make it appear that the increase in noise in a rural area would not be so dramatic. To us the noise is at times overwhelming and we can’t understand how this noise can be acceptable.

“The bright red blinking lights are still an issue, we can’t and don’t enjoy the very reason that we built our home here in Ocotillo. We are confined to the inside of our new prison home at night time when most people that live in the desert like to get outside and cool off. We are doing our best to plant trees and try to block some of the lights, but trees don’t grow tall very quickly.

“What can the BLM do to make us more comfortable and safe in our home with the continuing nuisance and hazards of these wind turbines? Has the BLM even noticed that not one of the Ocotillo Wind workers live or stay here in Ocotillo on their off hours? Besides Ocotillo being an undesirable location to many, living near your work would normally have its advantages…

  1. With the sprawling useless projects it is about industry selling their “bridges to nowhere”. It does not really matter what goes wrong because the tab is being picked up by the taxpayer.

  2. The youtube video is of a worker applying grease with a grease gun to the blade bearings, are you folks in the business of speculation or providing facts?

  3. George Rawlins – Nice try, the fact of the matter is they have came out and said they are doing a repair to the root segment of the blades and the repair description is worded something along the lines of drilling a series of holes at the root segment, injecting glue or adhesive and inserting bolts. I can more pictures and documents and dates if you still don’t get it.

    Below is a small extract of the letter we received from Ocotillo Express LLC explaining the blade repair:

    Siemens concluded that the fracture happened as a result of insufficient bonding at route and of the main blade. “Root Segments: are pre-cast inserts used to construct the blade route and are supplied to Siemens by a number of suppliers. These “root segments” are bonded to a fiberglass layer as part of the blade manufacturing process. The insufficient bonding was caused by improper surface preparation of root segments.
    As of June 25 all Siemens wind turbines with B53 blades globally have been inspected and a small number of blades will be replaced because indications of insufficient bonding were discovered.
    As a precautionary measure, Siemens will provide any minor modifications in the field to all existing B53 blades worldwide including Ocotillo wind. The upgrade will provide an extra level of protection by enhancing the bond between the precast route segments and the fiberglass layer. Siemens has validated this upgrade and an independent certifying authority for the wind energy industry has certified that the upgraded blades are safe for continued long term operation.
