The UK grid, focused on adding valuable renewable generation, will rely on natural gas–fired generation for many years to come. One of the most recent additions is the Langage Power Plant, designed for quick response and low load “parking” at night while remaining below air emissions limits. With an extraordinary architectural design that blends into the natural surroundings, Langage is now a local landmark.

This summary of results from a recent Platts/Capgemini survey of North American utility executives looks at what respondents had to say about all things related to the smart grid. Nearly half of respondents’ utilities have a smart grid strategy in place, while the other half said their utility has one in development.

The Panoche Energy Center is a 400-MW simple-cycle power plant using four of General Electric’s GE LMS100s with fast-start capability. Dispatched by Pacific Gas & Electric to meet regional power and grid stabilization needs, the project entered commercial service two months earlier than planned. Panoche is the largest LMS100 peaking facility in the U.S.

At the Ras Laffan Power Co. facility, the 756-MW net combined-cycle plant and the integrated 40 million gallons per day desalination plant are working in tandem to provide abundant, reliable electricity and desalinated water to residents of the State of Qatar, the most prosperous nation in the Middle East.

There’s nothing slow about the fast-track operations at the new 870-MW Sloe Centrale Power Plant. The combined-cycle plant is designed for 250 starts per year and is capable of supplying power to the grid within a mere 30 to 40 minutes. In addition to its impressive rapid load response, the gas-fired plant produces low CO₂ and NO_x emissions by using the latest technology. It also attains an efficiency of 59%.

The National Security Agency is launching a program to protect the grid from cyber attack, along with other civilian and military critical infrastructure, while a new Department of Energy report highlights grid vulnerabilities.

Cap and trade officially died on July 22 when Senate Majority Leader Harry Reid announced at a news conference that the Democratic Caucus was unable to reach a consensus on any form of energy bill, even a recent short-lived version that proposed reducing carbon emissions from only the utility sector. I predict that carbon cap and trade is now dead for at least a decade, maybe longer.

Now that the 412-MW Timelkam Power Plant has replaced a 47-year-old coal-fired power plant located in the Vöcklabruck District, northern Austrians can bid auf wiedersehen (goodbye) to high levels of air pollution. Compared to its predecessor, the new gas-fired combined-cycle plant has dramatically cut CO₂ and NO_x emissions and produces seven times more energy.

The nuclear renaissance has been in play for several years yet not a shovel of dirt has been turned. Why should anyone believe that Nuclear 2.0 will be an improvement?

What’s in a name? Would coal ash labeled as “special” hazardous waste be as easily recycled as that labeled nonhazardous waste?

The 3,600-MW West County Energy Center, with two recently commissioned power blocks and a third just entering start-up, is the first “greenfield” combined-cycle plant constructed by FPL since the 1970s. Thanks to FPL’s long history with repowering projects, the project team commissioned Unit 2 seven months early, with no operator errors during start-up. At just over $600/kW, the cost of the plant was a bargain.

Feed-in-tariffs (FITs)—above-retail rates paid for renewable power that producers "feed" into the grid—are gaining momentum all over the world as a means of driving project growth. Here are some of those established and proposed FITs.

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?
