The State Grid Corp. of China (SGCC) in July put into operation the world’s first ultra-high-voltage direct current (UHVDC) superhighway when it commissioned the Xiangjiaba-Shanghai link. The ±800 kV project, completed in 30 months—a year ahead of schedule—has the capacity to transmit up to 7,200 MW from the Xiangjiaba hydropower plant in southwest China to Shanghai, the country’s leading industrial and commercial center, about 2,000 kilometers (km) away.

Summer peaks are still with us, and every unit on your system must be prepared to operate at a moment’s notice. Spot power prices are so high that you expect phone calls asking for a few more megawatts from your units. Then your plant chemistry lab calls to report a condenser tube leak. Your options are few: Shut down immediately and get charged with a forced outage, ignore the leak and keeping running until fall, or schedule a maintenance outage next weekend and hope the leak can be found and fixed. In Part I, we examine what you need to know in order to make an informed decision. In Part II, we’ll explore the actual damage mechanisms.

The Massachusetts Supreme Judicial Court on Tuesday upheld the Energy Facilities Siting Board’s authority to overrule community opposition and allow permits for the controversial Cape Wind offshore wind farm in Nantucket Sound. The case is being viewed as the last major legal hurdle facing the 130-turbine project.

Imagine, a tablet computer than can surf the web, run word processing, take and send pictures, and run on sunlight. That’s what the government of India says it can produce…for $35 each. Imagine all the things your organization could do with computers that are essentially commodities.

At the end of June, Xcel Energy fired up a demonstration project that integrates a 4-MW parabolic trough solar technology with an existing 44-MW coal-fired power plant.

Most countries are trying to increase the percentage of their electricity supply that comes from renewable sources. But because capital costs for renewable generation still, in most cases, are higher per kilowatt-hour than for fossil-fueled power, governments are looking at all options for encouraging the development of greater renewable capacity. Feed-in tariffs (FITs) are one policy tool that has been used, most notably in Europe. Now North America is testing FITs as well.

Weeks after the city of Mattoon, Ill., withdrew from it, the FutureGen Alliance on Tuesday said it would support the U.S. Department of Energy’s (DOE’s) plans for the revamped FutureGen project—but only if the alliance and the agency could reach agreement on terms and conditions by this fall.

“Electricity use and gross national product [are] strongly correlated. The relationship…is so important that it should be considered in developing…energy and economic policies [which] seek to lower the real costs of electricity supply,” U.S. National Academy of Sciences, 1986

Renewable energy information services provider 3TIER in July confirmed with its publication of wind performance maps what U.S. wind developers with poor generation numbers had been suggesting earlier this year: A long-lasting El Niño event paired with a North Atlantic Oscillation event caused wind speeds to slump abnormally from the fall of 2009 through spring 2010.

A defining challenge for the U.S. electricity industry is to economically integrate renewable energy facilities into grid operations without sacrificing reliability. Bulk energy storage options are commercially proven technologies that enable that integration most expediently. Existing and emerging national and state policy frameworks are supporting their application in projects under development throughout the country.
