Hill International, the global leader in managing construction risk, announced today that its Brazilian subsidiary Engineering S.A. has received four contracts to manage the construction of four new wind farms located in the Brazilian states of Piauí, Ceará, Salvador and Pernanbuco.
GE today announced that it will supply Golden West Power Partners LLC with 147 GE 1.7-100 brilliant wind turbines for the Golden West Wind Farm in El Paso County, Colo. Once operational, the Golden West Wind Farm will produce 249.9 megawatts of electricity, which would be equivalent to the required energy needs of approximately 77,500 homes in the United States.
Siemens Canada has expanded its wind power footprint in Canada to the Province of Alberta via an agreement for Mainstream Renewable Power’s Oldman 2 wind project. The deal will see Siemens supply, deliver and commission 20 SWT-2.3-101 wind turbines with a hub height of 80 metres and blade length of 49 metres.
ALLETE Clean Energy, a subsidiary of ALLETE, Inc., has signed an acquisition agreement to purchase wind farms in Minnesota, Iowa and Oregon from The AES Corporation in early 2014 and has also signed an option agreement to acquire a fourth wind energy facility in Pennsylvania in mid-2015.
A new estimate of bat deaths caused by wind turbines concludes that more than 600,000 of the mammals likely died this way in 2012 in the contiguous United States. The estimate, published in an article in BioScience, used sophisticated statistical techniques to infer the probable number of bat deaths at wind energy facilities from the number of dead bats found at 21 locations, correcting for the installed power capacity of the facilities.
Although wind resources in the U.S. are abundant, the cost of generating wind energy is still prohibitively expensive when compared to natural gas and fossil fuels. Researchers have documented that one of the key reasons the costs remain high is because wind turbines have shorter lifespans compared to other energy-producing technologies, which can be directly linked to wear and tear caused by turbulence.
Growth in offshore wind generation is expected to play a major role in meeting carbon reduction targets around the world, but the impact of construction noise on marine species is yet unknown. A group of scientists from the United Kingdom and the United States have developed a method to assess the potential impacts of offshore wind farm construction on marine mammal populations, particularly the noise made while driving piles into the seabed to install wind turbine foundations. Their work is published in the November issue of Environmental Impact Assessment Review.
Today, GE announced its 3.2-103 brilliant wind turbine, producing a 5 percent increase in energy output compared to GE’s current model. Building on the strong performance of GE’s 2.5-megawatt fleet, the 3.2-103 generates more power for medium-to-high wind speed sites. With hub height flexibility of 70 to 98 meters, the 3.2-103 helps wind farm developers generate higher annual energy production in tip-height constrained sites.
ABB, the leading power and automation technology group, has won a significant order from the Dutch-German transmission system operator TenneT to supply an AC (alternating current) power transmission link connecting Sandbank, an offshore wind farm in the German North Sea, to the HVDC (high-voltage direct current) converter station SylWin alpha.
Modern gas turbine power plants represent one of the mostefficient and economic conventional power generation technologiessuitable for large-scale and smaller scale applications.
