Faced with soaring energy prices, researchers and developers worldwide are giving compressed air energy storage (CAES)—a technology almost 50 years old—a dusting, a spit shine, and a new life. In particular, they see it as a critical component for the dispatch of wind and other renewable power. The technology, which involves storing off-peak-generated energy in […]

Worldwide energy consumption is projected to grow 50% between 2005 and 2030, driven by robust economic growth and expanding populations in the world’s developing countries, the U.S. Energy Information Administration (EIA) said in a reference case projection from its International Energy Outlook 2008 in June.

In early August, a special transport departed from Voith Siemens Hydro’s Heidenheim workshop bearing the company’s 300-ton, 300-MVA hydro motor-generator back to Schluchseewerk AG’s Wehr pumped-storage station in Germany’s Black Forest.

Documenting changes to the distributed control system and other digital plant applications should be considered a critical element of managing risk—and of safe, efficient daily operations and maintenance. Coming up with a practical configuration management approach, though, isn’t easy.

By Steven F. Greenwald and Jeffrey P. Gray David Crane, the CEO of NRG Energy, was recently quoted in a widely disseminated publication as saying: “It is a moral imperative that we take steps to reduce CO2 concentration in the earth’s atmosphere.” One might expect those reacting to Crane’s comments (made in a February 2007 […]

In our April 2008 issue, the article “The aging workforce: Panic is not a strategy” focused on how to reconfigure human resource practices in order to find enough well-trained new personnel to replace the large number of baby boomers who will be retiring in the next few years. This month we profile several utilities that are using innovative approaches to recruit younger technical staff and skilled craft labor to fill positions being vacated in growing numbers by retiring employees.

It is rare indeed to witness, at an otherwise staid industry forum, the public rebuke of the country’s most prominent supplier to the electric power industry. But at the Keynote session and Power Industry CEO Roundtable of the 2008 ELECTRIC POWER Conference & Exhibition in Baltimore this May, Milton Lee, general manager and CEO of […]

Power plant training: New techniques required

By Steven F. Greenwald and Jeffrey P. Gray These should be good times for environmentalists who focus on “green” energy policy. More than half the U.S. states have adopted renewable portfolio standards (RPS) that require utilities to meet specific renewable generation targets, and many are considering additional actions to reduce greenhouse gas (GHG) emissions. Such […]

Last month, POWER explored the growing importance of the smart grid, which is envisioned as using digital technologies to enable integrated, real-time control of all the system’s elements, from generation to end use. This month we focus on the emerging technology of microgrids: controlled groupings of dispersed generation sources that are connected to the main electrical grid but that can function independent of it. We examine their benefits and their potential impact on 21st-century utilities and their customers.

Control systems used by utilities and other operators of America’s industrial infrastructure increasingly rely on an Internet connection that makes them as vulnerable to hackers as any computer or network. One reason many utility control systems are vulnerable is that, unlike your ISP’s systems, they don’t record an audit trail that reveals the source of the attack.

Until very recently, common wisdom held that the price of renewable energy would fall as legislative procurement mandates ensured its long-term demand. The resulting growth in supply and sales would spur investment in the field, create economies of scale, and accelerate progress down the technology learning curve. Something unexpected, however, happened along the way. Though […]

The next-generation power grid—enhanced by digital technologies throughout the network to give generators, distributors, and customers greater control—promises to improve efficiency and lower operating costs. This year, in the most full-scale effort yet, Xcel Energy begins introducing intelligent grid technologies that it hopes will make Boulder, Colo., the first Smart Grid City.

The advent of the Smart Grid will bring a new driver for value creation to the electric power industry: economies of connection. In the future, the Smart Grid may offer our industry improved returns more typical of Internet-based businesses like eBay, Amazon, and Google to replace the diminishing returns typical of traditional “steel in the […]

In early February, Western GeoPower (WGP) announced its termination of a 20-year geothermal power purchase agreement (PPA) with Pacific Gas and Electric Co. (PG&E). A WGP press release explains that the company terminated the agreement because a regulatory approval condition had not been obtained within a 180-day time period stipulated in the PPA. WGP’s CEO, […]

The nuclear renaissance is likely to slow next year with a new tenant in the White House and many key regulatory positions in flux. Nuclear industry leaders are especially concerned that rules for construction loan guarantees will fall victim to the “wait and see” disease that infects those inside the Beltway every four years. If those rules aren’t in place before this November’s election, the nuclear renaissance may revert to the Dark Ages.

Managing ongoing threats to power plants’ digital, telecommunications, monitoring, control, and automation systems is no longer just a good idea. It’s an essential element of superior plant operations and now a regulatory requirement as well, thanks to new critical infrastructure protection standards recently approved by FERC.

The new, 424-MW Castejon 2 combined-cycle plant designed and built by Alstom was recently given its provisional acceptance certificate. Alstom used its “Plant Integrator” approach to fast-track delivery of a plant just like Castejon 1, which averaged 98% availability during its first three years of operation. That kind of performance is crucial to generators operating in the Spanish merchant power market—or any market.

Leaders in the utilities sector talk a lot these days about talent. On one hand, they express concern about facing a shortage of knowledgeable staff as 76 million baby boomers exit the workforce. On the other, they worry about where they’ll find enough qualified people to remain competitive in light of the fierce battle for engineering talent that globalization has created. The antidote to these worries lies in reconfiguring HR practices.

If you enjoy POWER magazine’s New Products department, you’re going to love the ELECTRIC POWER 2008 Exhibition. You’ll be able to see and feel the latest tools of the trade and talk to the folks who provide them to the generation industry. Here’s a sneak peak at what awaits you on the exhibit floor May 6 to 8 at the Baltimore Convention Center.

Lower Colorado River Authority recently put two separate plants at its Lost Pines Power Park under one functional management system. The project has already deployed a layered wireless infrastructure that allows the two plants to communicate at a fraction of the cost of a wired solution while providing a platform for optimizing work processes and reducing operating costs. What’s not to like?

At this juncture our industry is faced with greater uncertainty and opportunity than ever before. That’s why you won’t want to miss all the information, ideas, and networking available at the power generation industry’s premier event in May.

Given a chance to make a positive change in California’s wholesale generation market, the California Public Utilities Commission (CPUC) in December opted instead to maintain the state’s existing “hybrid” market model. That decision will further restrict meaningful opportunities for independent power producers (IPPs) and increase the likelihood that future generation will consist of utility ratebase […]
