Question: What was the original name of the manufacturer of the wind turbines used by The Hackberry Wind Project?
Context: The Vansycle I Wind Project (formerly Vansycle Wind Project) is a wind farm in Umatilla County, Oregon.  It consists of 38 Vestas 0.66 MW wind turbines at the upper end of Vansycle Canyon with a collective nameplate generating capacity of 25.08 MW.  The project was the first commercial wind energy project constructed and operated in Oregon and began operation in December 1998. The Gros-Morne Wind Farm is a large 211.5 megawatt (MW) wind farm comprising 141 1.5MW wind turbines that provides electricity to over 40,000 homes.  It is located about 50 kilometers north-west of Gaspe, Quebec and it is owned and operated by Cartier Wind Energy.  The wind farm was constructed in 2 phases, the first phase, involving 100.5 MW and 67 wind turbines, was completed on November 29, 2011.  Construction of phase II involved 111MW and 74 wind turbines, and it was finalized on November 6, 2012. The Smoky Hills Wind Farm (Phase I & Phase II) is a 250 megawatt (MW) wind farm in Lincoln and Ellsworth Counties, 140 miles west of Topeka in Kansas, north of Ellsworth.  The farm is operated by Enel Green Power.  Highway K-14 and Interstate 70 pass through parts of the wind farm, with clear views of many of the wind turbines.  The project uses 56 Vestas V80 1.8 MW wind turbines and produces enough electricity to power some 37,000 average Kansas homes annually.  s of 19 2008 , phase II is under construction with 99 GE 1.5 MW wind turbines for an additional 148.5 MW, to bring the total nameplate capacity to 249.3 MW. The great majority of wind turbines around the world belong to individuals or corporations who use them to generate electric power or to perform mechanical work.  As such, wind turbines are primarily designed to be working devices.  However, the large size and height above surroundings of modern industrial wind turbines, combined with their moving rotors, often makes them among the most conspicuous objects in their areas.  A few localities have exploited the attention-getting nature of wind turbines by placing them on public display, either with visitor centers on their bases, or with viewing areas farther away.  The wind turbines themselves are generally of conventional horizontal-axis, three-bladed design, and generate power to feed electrical grids, but they also serve the unconventional roles of technology demonstration, public relations, and education. The Criterion Wind Project is a wind farm located on Backbone Mountain east of Oakland, Maryland, United States.  The project has a rated capacity of 70 MW and uses 28 Liberty Wind Turbines manufactured by Clipper Windpower.  Each of the wind turbines is about 415 feet tall.  The Criterion Wind Project is owned by Criterion Power Partners, LLC, which is a subisiary of Exelon, and interconnected with the transmission system of the Potomac Edison Company (a subsidiary of FirstEnergy).  Electricity and renewable energy credits from the project are sold to the Old Dominion Electric Cooperative under a 20-year supply contract. The Massachusetts Military Reservation Wind Project is located in Barnstable County, Massachusetts on the Massachusetts Military Reservation (MMR), also known as the Joint Base Cape Cod.  This Wind Project currently consists of one wind turbine, built in 2009, and two others recently completed in 2011.  The first turbine was a Fuhrländer 1500/77 wind turbine “with an 80 meter tower and a 77 meter rotor diameter.”  The two completed in 2011 were General Electric wind turbines.  Each of these GE 1.5-77 wind turbines outputs 1.5 MW of power on top of an 80 meter tall tower.  Therefore, the total net capacity for the MMR Wind project is approximately 4.5 MW.  Clearance may soon become available to build more turbines.  (See the “New Turbines” section below for more information).  The contracting company hired to build all three of the turbines is called ECC Corporate, and the plant code and utility ID of the facility are 57253 and 56619, respectively. The Hackberry Wind Project is a US $350 million wind farm in Shackelford County, Texas.  The project consists of 72 Siemens wind turbines with a total capacity of 166 megawatts.  The energy is used by residents of the City of Austin and surrounding communities.  Construction on the project began in January 2008 and was finished in December 2008, on-time and under budget. Tehachapi Pass Wind Farm is one of the first large-scale wind farms installed in the U.S. Wind development in the Tehachapi Pass began in the early 1980s by James Dehlsen and Zond Corporation.  The first set of wind turbines installed were of American-made Storm Master brand, however they proved troublesome and eventually had to be replaced.  Dehlsen quickly turned to Danish-built machines later, thus comprising the majority of the turbines at the pass.The area hosts a multitude of wind farms, comprising one of California's largest wind resource areas.  The pass is undergoing much repowering activity.  The area has multiple generations of wind turbine technology installed, including both single and double-blade turbines, as well as the more modern three-blade horizontal axis design.  The older generation turbines generate kilowatts, and the modern turbines installed generate up to 3 megawatts, depending on the specific turbine and manufacturer.  The Tehachapi wind resource area is a net exporter of generation to other parts of the state of California.  A state initiative to upgrade the transmission out of Tehachapi (Tehachapi Renewable Transmission Project) began in 2008 and was expected to be completed by 2012.  This has opened the door to further regional wind power development and multiple projects are expected to be installed to utilize that capacity.  A prime location for viewing the turbines is off of State Route 58 and from Tehachapi-Willow Springs Road. Siemens Wind Power, (formerly Danregn Vindkraft A/S and Bonus Energy A/S) is a wind turbine manufacturer established in 1980 as Danregn Vindkraft.  Bonus Energy was acquired by Siemens of Germany in 2004.  The organisation became a separate division of Siemens in 2011, with headquarters established in Hamburg, Germany. The Altamont Pass Wind Farm is located in the Altamont Pass of the Diablo Range in Northern California.  It is one of the earliest wind farms in the United States.  The first wind turbines were placed on the Altamont by Fayette Manufacturing Corporation on land owned by cattle rancher Joe Jess.  The wind farm is composed of 4930 relatively small wind turbines of various types, making it at one time the largest wind farm in the world in terms of capacity.  Altamont Pass is still the largest concentration of wind turbines in the world, with a capacity of 576 megawatts (MW), producing about 125 MW on average and 1.1 terawatt-hours (TWh) yearly.  They were installed after the 1970s energy crisis in response to favorable tax policies for investors.
