Siemens Energy in June announced it had produced the first batch of its new B75 Quantum wind turbine rotor blades, fiberglass components 75 meters (m) in length that were cast in one piece (Figure 3). The blades were manufactured to be installed this fall on Siemens’ second prototype of the German firm’s SWT-6.0 6-MW offshore […]

Two Republican lawmakers are probing whether the Federal Aviation Administration (FAA) disregarded safety concerns and approved the Cape Wind project—the nation’s first offshore wind project—for political reasons.

The Department of the Interior (DOI) on Monday announced the release of final environmental impact statements for a proposed wind power complex in Wyoming with a nameplate capacity of 3,000 MW and publication of an environmental assessment for commercial wind leases and site assessment activities on the Outer Continental Shelf (OCS) offshore Rhode Island and Massachusetts.

The Federal Energy Regulatory Commission (FERC) has the responsibility for ensuring just and reasonable rates and preventing undue discrimination by public utility transmission providers. Last year FERC defined a new framework for public utilities and regional transmission organizations planning new transmission networks. The framework is provided in Order No. 1000—Transmission Planning and Allocation by Transmission Owning and Operating Public Utilities. The Final Rule was issued on July 21, 2011, and reaffirmed by Order No. 1000-A on May 17, 2012.

India’s long-term annual economic growth rate is projected at over 7%, and the country is investing in its hydroelectric, nuclear, and renewable resources. However, the primary fuel used to produce electricity remains coal, and the government has ambitious plans to significantly increase coal-fired capacity. Those plans have been challenged by a number of unexpected factors that threaten to stifle India’s economic growth.

Panelists at ELECTRIC POWER discussed how U.S. utilities choose renewable power generation technologies based on their geographic locations, state requirements, economics, and other criteria—including reliability and federal regulations.

Denmark’s parliament in late March agreed to a new energy strategy seeking to wean the country off oil and gas. It could result in the Nordic country cutting its greenhouse gas emissions 34% by 2020, compared to 1990 levels, and decreasing energy consumption by more than 12%, compared to 2006.

Spanish wind turbine manufacturer Gamesa on Monday said it would start the permitting process for the installation of its first offshore prototype, the 50-Hz G128-5.0 MW at Arinaga Quay in Spain’s Gran Canary Island—not Cape Charles, Va., as it had initially proposed. The decision was driven by technical and wind resource considerations, offshore market trends, and investment return criteria, the firm said.

The UK opened two massive offshore wind farms this February on the Irish Sea off the UK’s Cumbrian coast. DONG Energy, SSE, OPW, and a consortium of Dutch pension fund service provider PGGM and Ampere Equity Fund began commercially operating the 367-MW Walney wind farm, estimated to cost $1.58 billion, and Danish wind firm Vattenfall inaugurated the Ormonde Offshore Wind Farm.

Chinese state entity State Grid Corp. of China (SGCC) and battery maker BYD in January said they had finished construction on what they call “the world’s largest battery energy storage station”—a project in Zhangbei, Hebei Province that combines 100 MW of wind and 40 MW of solar capacity, a smart power transmission system, and 36 MWh of energy storage in arrays “larger than a football field.”
