As state regulators examine whether the smart grid benefits consumers, a federal agency is looking at what information consumers need to take advantage of the technology.

The enforcement mechanisms of the environmental statutes in the 1960s were both cumbersome and ineffective.

Renewable electricity generation has many environmental advantages, but adding large amounts of far-flung renewable resources to a grid requires increased operating flexibility from dispatchable generators when the wind doesn’t blow or the sun doesn’t shine. One promising option: A combined-cycle plant based on Alstom’s GT24/GT26 combustion turbine can be “parked” at approximately 20% plant load while producing emissions comparable to those during baseload operation—with little loss in thermal efficiency. When demand returns, the combined cycle can return to baseload within minutes.

The Nuclear Regulatory Commission (NRC) last week released a report that deemed the mixed oxide (MOX) fuel facility at the Savannah River site near Aiken, S.C., safe. The 568-page document essentially allows licensing to proceed for the plant to make nuclear reactor fuel from plutonium waste.

Dealing with whistleblowers can be human relations quicksand, where unseen errors that could cost a company millions lay in the path to resolution of employee complaints. Recent legislation makes dealing with whistleblowers an even bigger challenge.

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.

The California Energy Commission (CEC) unanimously approved construction of the 250-MW Beacon Solar Energy Project last week. The project, proposed for construction in Kern County by a NextEra Energy subsidiary, is the first solar thermal plant permitted by the state in 20 years.

The plurality of regulatory proceedings originate with utilities seeking to improve their profitability. Profitability being part of the public interest, these submissions deserve our attention. But what if these filings are “framed” to divert our attention away from our public interest mission?

Spain in July inaugurated another major concentrated solar power (CSP) power station. The 50-MW La Florida parabolic solar trough plant in Alvarado Badajoz (in the west of the country), increases Spain’s solar nameplate capacity to 432 MW—beating out the U.S., which produces 422 MW from solar installations.

In 2010, U.S. wind power development has slowed, coal-fired power development remained stalled, and the much-awaited renaissance of nuclear power took a few tentative steps forward. That left natural gas power development as the last man standing.

India’s parliament on Monday approved a long-delayed civil nuclear agreement, crucial legislation that could allow U.S. firms to proceed with deals to build nuclear power plants in that country. Firms had been reluctant to build nuclear facilities without a law that would limit their liability in the event of an accident.

Water resources represent essential inputs into energy production while, at the same time, energy availability is a key factor in effective water resource use.

A £42 million marine power infrastructure project that will function as an “electrical socket” in waters 50 meters (m) deep and nearly 16 kilometers (km) off the coast of Cornwall in South West England set sail toward its proposed location this July.

While the Obama administration in Washington is lauding solar energy as a major part of an alleged transition to renewable energy, the U.S. companies that make solar modules to turn the energy in sunlight into electric power are hurting. Prices for PV cells are falling, and domestic firms are seeing waves of red ink on their books, falling investor interest, and are responding by moving production offshore.
