Vineyard Wind Blades GE Vernova Gamble Continues

Blades for Vineyard Wind are hybrid blades containing far less carbon fiber making them easier to manufacture and less expensive to produce than the competition.
.
The blades were made by LM Wind Company owned by General Electric.  

.

A prototype blade was tested and certified at the Massachusetts Clean Energy Center, clearing the way to produce 150 blades in Canada. The 351-foot blade did not fit in the test site, necessitating cutting into two parts.
.
1. No torsion test was done on the entire blade.
2. No field test was done for one year in a rough ocean environment.

.

These 351-foot blades travel in an 800-foot circle. The wind speed at the bottom could be far less than at the top, and the blade's torsion could cause the tip to hit the tower. LM Wind, aka LM Wind Glassfiber, had this same problem in 1997 and had to place devices to warn of too much torsion.
.
Torsion testing is twisting the body of the entire blade while one end is held fast or turned in the opposite direction. This test was never done instead MassCEC engineers extrapolated figures on the hybrid blade.
.
Manufacturing has had problems over the years, starting with a fire at the LM Wind Company in Gaspee, Quebec, on May 11, 2023. 
.
On July 13, 2024, one of the blades broke off the coast of Nantucket spewing 50 tons of trash into the ocean environment. It is still washing onshore and the clean-up costs remain unknown.
.
On October 25, 2024, it was disclosed the LM plant had quality control issues. 
.
It appears up to ten percent of the 150 blades are defective. 
.
Recently it was announced the project is 80 percent complete leaving blade installation at 20 percent of the project. 
.
Around 90 percent of projects fail due to rushing goals and lack of communication. 
.
The BSEE, Bureau of Safety and Environmental Enforcement needs to review during operation, a blade sees various wind speeds as it scribes an 800-foot circle. Wind speeds are much higher near the top than near the bottom of the circle. The wind speeds significantly vary from side to side of the circle. Such varying winds produce repeating, dynamic torsional effects on the blade. 
.
The integrity of an experimental blade design can only be determined under real-life testing, on a mast in the North Sea for at least a year, to ensure the blades see all weather conditions.  
.
It took from December 2022 to produce 150 blades ten percent defective. 
.
It's time for GE Vernova to use a smaller more dependable blade with a proven history.

Maine Center For Public Interest Reporting – Three Part Series: A CRITICAL LOOK AT MAINE’S WIND ACT

******** IF LINKS BELOW DON'T WORK, GOOGLE THEM*********

(excerpts) From Part 1 – On Maine’s Wind Law “Once the committee passed the wind energy bill on to the full House and Senate, lawmakers there didn’t even debate it. They passed it unanimously and with no discussion. House Majority Leader Hannah Pingree, a Democrat from North Haven, says legislators probably didn’t know how many turbines would be constructed in Maine if the law’s goals were met." . – Maine Center for Public Interest Reporting, August 2010 https://www.pinetreewatchdog.org/wind-power-bandwagon-hits-bumps-in-the-road-3/From Part 2 – On Wind and Oil Yet using wind energy doesn’t lower dependence on imported foreign oil. That’s because the majority of imported oil in Maine is used for heating and transportation. And switching our dependence from foreign oil to Maine-produced electricity isn’t likely to happen very soon, says Bartlett. “Right now, people can’t switch to electric cars and heating – if they did, we’d be in trouble.” So was one of the fundamental premises of the task force false, or at least misleading?" https://www.pinetreewatchdog.org/wind-swept-task-force-set-the-rules/From Part 3 – On Wind-Required New Transmission Lines Finally, the building of enormous, high-voltage transmission lines that the regional electricity system operator says are required to move substantial amounts of wind power to markets south of Maine was never even discussed by the task force – an omission that Mills said will come to haunt the state.“If you try to put 2,500 or 3,000 megawatts in northern or eastern Maine – oh, my god, try to build the transmission!” said Mills. “It’s not just the towers, it’s the lines – that’s when I begin to think that the goal is a little farfetched.” https://www.pinetreewatchdog.org/flaws-in-bill-like-skating-with-dull-skates/

Sign up today and lend your voice and presence to the steadily rising tide that will soon sweep the scourge of useless and wretched turbines from our beloved Maine countryside. For many of us, our little pieces of paradise have been hard won. Did the carpetbaggers think they could simply steal them from us?

We have the facts on our side. We have the truth on our side. All we need now is YOU.
