Fairhaven’s north turbine suffered a setback when a component blew out and caught fire on April 7. According to the fire department report, just before 3:30 p.m., a public works employee heard a “bang” and saw smoke coming from one of the wind turbines (WT).
“We lease the land to them and have a power purchase agreement,” Bott said. “They’re paying us lease payments, and we're getting some tax on the personal property.” The town’s agreement doesn’t make allowances for shutdowns, however, so KWI is on the hook for paying Kingston regardless of whether the blades are spinning, he added.
Independence Wind Operations Manager, Benjamin Cleaves, has informed Kingston town officials that the Kingston Wind Independence (KWI) turbine has been shut down indefinitely due to a possible defect in the equipment.
An official with Applied Materials says its wind turbine on the Dory Road campus in Gloucester should be functioning properly within six months.
The turbine has not been consistently operational since its installation in 2011. The Wilmington-based energy company that installed it, Lumus Construction, eventually defaulted, and Hanover Insurance, the company that held Lumus’ surety bond, became involved, Clarkson said.
The Air Force first shut down the 389-foot-tall turbine, manufactured by Fuhrlander, in May of 2014 after there was an indication the gearbox was failing, Forbes said. Metal flakes were found in some oil, she said. ...It took time to get the funds approved for a new gearbox and a contract to hire a company to do the work. The project cost is $600,000, Forbes said.
Having ordered the necessary parts, turbine owners are hoping that Fairhaven's north turbine will soon be blowing in the wind once more.
From November through March the turbine was more or less fully functional. ...Then the brakes deployed incorrectly one day. “They’re machines and machines break. Not only do machines break, but turbines are a couple of hundred feet up in the air, so they are a little more difficult to repair.”
The Lynnway wind turbine has a cracked rotor due to cold weather. Repairs will begin Feb. 18.
FAIRHAVEN — The north turbine is down for maintenance after a routine inspection found its foundation to be slightly off-level.
"I've talked to a lot of people familiar with lightening strikes in other projects and they have spent lots of time, money, and engineering to chase down the source of the problem, and in the end there is nothing you can do to solve a severe lightning strike," Shah said. "...Turbines get hit by lightning all the time."
Fuses in the turbine have been replaced, but the troubleshooting of systems that "come into play in extreme circumstances" is continuing, Shah said. Determining whether there are problems with the any of the systems requires the turbine to be running.
The Independence wind turbine is offline after damage to its computer system during this weekend's electrical storm.
The operators of Scituate's wind turbine say they've lost nearly $19,000 in revenue since the turbine was damaged by lightning on June 24, and they say they're uncertain when it will be operating again. In the two weeks since it was struck by lightning, the turbine would have generated an average of 168,800 kilowatt hours, or $18,900 in revenue.
The turbine was supposed to be completed and operational by February 2011, but the company hired to install it, Woburn-based Lumus Construction, has run into a series of problems, including an accident in December in which a worker fell 24 feet inside the turbine tower and had to be removed by a specially trained rescue team.
Sheila Manning, the secretary in the town administrator's office, said Wednesday that Solaya, the company that operates the turbine, has been testing and replacing wiring and other parts of the turbine's electrical control system. The 390-foot-high turbine was hit by lightning around 8 or 9 p.m. June 24, as a strong thunderstorm rolled through the area.
Problems with the Hanover wind turbine have been coming up so frequently that Lumus construction, the company building it, wants the India-based manufacturing company, Siva, to send an inspector from India to help get the turbine up and running. But that inspector needs to get here first.
Sumul Shah, president of Solaya, the operators of Scituate Wind, confirmed the turbine was hit by lightning and has numerous electrical issues that are still being worked out. As of Monday afternoon, Shah said repairs would continue for the next few days.
If it turns out it is a manufacturer's problem the $95,000 PMLD paid up front for the gear box replacement will be returned and Jake would pay for the gearbox, said Allen. Then the company will look at the loss of revenue issue, he said.
The town's wind turbine, located at Portsmouth High School, has remained motionless since May 10 after an error code alerted town workers to a problem on site. "The short story is Lumus believes the fault is in a pressure sensor and they are having difficulty locating a replacement part."
