The number of spinning giant turbines standing high above Gloucester's Blackburn Industrial Park is now, temporarily at least, down to one.
Solaya’s Shah said his company has crews on the ground working to repair the leaks keeping at least one of the city’s turbines from fulfilling its purpose. The city is also budgeted to take in $78,075 in in-lieu-of tax payments from Equity this year, within a few dollars of its payments for the last three years. But the electricity revenues have continued to fall short of the annual $450,000 projected by then-Mayor Carolyn Kirk and Equity officials when the turbines were installed in December late 2012.
The Hanover fire and highway departments responded to a report of smoke coming from the wind turbine on Pond Street Friday morning.
Hanover Fire Crews were called to the scene of a wind turbine fire.
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.
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.
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.
