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.

Hamworthy Peabody Combustion introduced the ECOjet ultra-low-NOx burner. Offering ultra-low burner nitrogen oxide capacities (<30 parts per million) with little or no flue gas recirculation, the burner can be used with a full range of gaseous fuels and with package, industrial, and utility boilers, including single and multi-burner wall-fired, turbo, and other boiler types. Ignition […]

While the New Year officially begins Jan. 1, in my mind, the year really begins the day after Labor Day. That’s when Washington again takes up its never-ending, seldom-succeeding task of pushing the policy boulder up the hill.

GE launched what it is calling the world’s first two-stage turbocharged gas engine this June.

Poly Performance’s newly launched Quick Release Fire Extinguisher Mount offers an innovative way to safely mount a fire extinguisher to any flat or round surface. The mount can be secured with either bolts or hose clamps. Configurable for any size fire extinguisher, the mount offers split-second removal to maximize emergency preparedness. Poly Performance manufactures the […]

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.

MHI, Foster Wheeler to Support FEED for UK CCS Project. A consortium of Mitsubishi Heavy Industries (MHI) and Foster Wheeler Energy Ltd. on August 5 announced that it had received an order from E.ON UK to support the front-end engineering design (FEED) for a post-combustion carbon dioxide (CO2) capture plant proposed as part of E.ON’s […]

Industrial health and safety equipment manufacturer Sensidyne released the SensAlarm Plus, an all-in-one gas detection system for monitoring oxygen, toxic, and combustible gases. The system functions as a single transmitter that offers “Test-on-Demand” and “Predictive Sensor Failure” features, in addition to accepting oxygen, electrochemical, catalytic bead, or infrared sensors. The system provides a large LED […]

We first reported on combined-cycle plant reliability concerns due to erosive wear and flow accelerated corrosion (FAC) in heat-recovery steam generator (HRSG) pressure parts at the 1999 EPRI Maintenance Conference. More than 10 years later, these damage mechanisms remain significant contributors to forced outages, pressure part repairs, and major component replacement.

Although mining practices often vary greatly according to the material produced and the value of the deposit, one common denominator is that mining of materials containing sulfide minerals creates acid mine drainage (AMD). AMD is one of the mining industry’s major environmental challenges.

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.
