A commercial wind turbine has failed at Otis AFB
Massachusetts Military Reservation - Air Force Center for Environmental Excellence
Owner/Operator: Air Force Center for Environmental Excellence
Host: Air Force Center for Environmental Excellence
Size: 1500 kW
Technology: 1 Furhlander 1.5 MW
Type: Customer Sited (100 kW+)
Commission Date: December 15, 2009
The Massachusetts Military Reservation (Otis Air Force Base) received and installed its 1.5-MW Fuhrlander turbine in late fall 2009. The turbine will partially power the Air Force's groundwater clean up efforts at the Base and is the first of a multi-phase wind development effort for the Reservation.

The federal government has an agenda to get a high formula of commercial wind turbine megawatts by 2020.
The NREL, National Renewable Energy Lab has a data base hidden from the public ! If the public knew for example one gear box company had over 600 gear box failures and is still in business the public would freak out !
The Furhlander 1.5 MW and all the AAER wind turbines built from 2008 on have the same type of gear boxes !
The owners of the turbines including Otis AFB are going to run the gear boxes into the ground and gamble on oil leaks and fires ! If they don't catch fire they'll change the gear box !

While I appreciate everyone's interest in the success of wind energy, I feel I must clear up the issues associated with the Otis Air National Guard Base wind turbine located at the MA Military Reservation. The owner/operator of the Otis ANG Base wind turbine is the Air Force Civil Engineer Center (AFCEC). Our name changed from Air Force Center for Engineering and the Environment (AFCEE) on 01 Oct 2012 after a reorganization. I am the project manager for the operation of our pump and treat systems, the plume cleanup, and the three 1.5 MW wind turbines installed by AFCEC/AFCEE at MMR. We have one 1.5 MW Fuhrlaender (FL-1577) wind turbine and two 1.5 MW GE wind turbines at MMR. We installed the wind turbines to offset the costs and environmental impact associated with our cleanup program.
The FL-1577 started operating on 02 Dec 2009. The GE turbines started opeating on 03 Nov 2011. Regarding the FL-1577 gearbox, it HAS NOT failed. We noticed some metal flakes in the gearbox oil this past January and had a borescope inspection done. The inspection showed pitting of the gear teeth caused by pressing the metal flakes between the teeth. The problem component in the gearbox appears to be a bearing. Based on Fuhrlaender's recommendation, we are continuing to run the wind turbine while we work on procuring a new gearbox that has a different/better bearing. We monitor the turbine continuously via remote monitoring for a variety of parameters and we have technicians who visit the turbine each weekday during rounds conducted for our treatment systems.
We expected the gearbox to last for 10 years and it still might but we are going to err on the side of caution and replace it given te results of the borescope inspection. I do not have replacement costs to report at this point as we are still developing the plan; but, I will be glad to provide this information when it is available.
As an engineer, I like to have facts and I like to see things work optimally. If they break, we determine why and we fix them. We don't waste our time on rumors. If anyone would like to get the facts on the wind turbines at MMR including how much they are saving the taxpayer and offsetting air emissions, please feel free to contact me at [email protected]

Hanover to terminate contract with turbine company

After nearly two years of delays, Hanover officials are terminating their contract with the company hired to build the town’s still-incomplete wind turbine.
Town Manager Troy Clarkson said Monday that the town had to cut ties with Woburn-based Lumus Construction because the company had failed to get the turbine up and running. The 210-foot structure is next to the town’s water treatment plant on Route 53 and was expected to provide most of the facility’s power.
“The contractor wasn’t fulfilling the contract,” Clarkson said.“The turbine needs to be spinning.”
Clarkson said the town would withhold the final $100,000 owed to the company and is seeking to recover money it already paid. He said a stipulation in the town’s contract requires Lumus to pay the town $1,000 for every day past an established completion date that the project goes unfinished.
Clarkson said 700 days had passed since the project’s completion date, so he expects the town to receive $700,000 from Lumus.
“We are absolutely prepared to do anything and everything” to recover the money, he said.
Selectmen Chairman John Barry said he supported the decision to terminate the company’s contract.
“There is a strong level of frustration with the fact the windmill isn’t spinning,” he said.
Clarkson said Lumus did not respond to the town’s termination notice within a seven-day window. The company’s website lists phone numbers for its main offices in Woburn and Portland, Maine, but neither number was in service Tuesday.
