The FutureGen Industrial Alliance Inc. selected Mattoon, Ill., as the site of the $1.8 billion FutureGen project just before Christmas, but the plant may never move off the drawing board.. FutureGen, the proposed prototype of a near-zero-emissions coal plant, is to demonstrate advanced technologies for coal gasification, electricity production, emissions control, CO 2 capture and […]

Integrated gasification combined-cycle (IGCC) technology, a process of gasifying coal that allows the capture of carbon dioxide emissions, has tremendous potential for meeting future baseload generation demand. Though it is one of the leading alternatives for producing clean power from coal, IGCC faces a precarious future due to rising capital costs and regulatory uncertainty. We’re […]

Employees of Alabama Power, a Southern Company subsidiary, routinely work near energized wires, intense heat, nuclear fuel, heavy equipment, moving vehicles, and pressurized equipment, as well as under other conditions that require exceptional safety attitudes and measures. Though it is vitally important to provide electricity to customers, neither company believes that doing so is worth […]

 Carbon control legislation made it out of a subcommittee of the U.S. Senate Committee on Environment and Public Works in late October, but no one is happy with it. The bill, S. 2191, America’s Climate Security Act of 2007, would direct the U.S. EPA to establish a program to decrease emissions of greenhouse gases (GHGs). […]

POWER readers today face severe problems in the electricity supply business. But a much bigger problem will soon burst on the scene: the peaking of world oil production. Experts have forecast peaking since shortly after the first U.S. well began production in 1859, and many subsequent forecasts of peaking have proven incorrect. Oil reserves dip […]

A utility executive responsible for procuring renewable power recently lamented that, at the time of contract execution, renewable “projects” are typically at a very preliminary stage of development, offering scant information about project specifics. Regulatory or other objectives often cause the utility to require that the power purchase agreement be executed before critical permits have […]

POWER congratulates DONG Energy and Siemens Power Generation on the October 18 inauguration of their 90-MW Burbo Bank Offshore Wind Farm. This project was the first commercial application of Siemens’ new 3.6-MW wind turbine and exemplifies how the right developer and supplier team can quickly add much-needed offshore wind power to a country’s generation mix.

Central Vermont Public Service developed the nation’s first farm-to-consumer renewable energy choice by using cow manure to generate electricity. CVPS gave beleaguered farms new economic hope; developed a generation system that provides clean, renewable energy; and helped solve numerous manure management environmental challenges. CVPS and Cow Power’s four member dairies are recognized as a 2007 Top Plant for generating renewable energy one cow at a time.

Concentrating solar thermal projects fell out of favor more than 15 years ago, when the last SEGS plant was commissioned. But advances in reflective mirror, thermal receiver, and tracking system technologies have significantly improved the systems’ energy conversion efficiency at a much lower capital cost. POWER recognizes Nevada Solar One as a 2007 Top Plant for pushing the limits of solar thermal technology and for being the first of a new generation of concentrating solar projects now being developed around the world.

Geothermal power is a unique renewable energy because it has the best potential capacity factor and is perhaps the only option for baseload power generation. U.S. Geothermal has constructed the first geothermal plant in Idaho in a generation by restoring an abandoned DOE demonstration project site that may possess a development potential of over 100 MW using proven power generation technology. The success of Raft River may well determine the future of geothermal energy production in Idaho.

This year, for the first time, the U.S. wind power industry is poised to push past the 3,000 MW installed per year milestone. At 20 MW, Steel Winds may seem like a footnote, but its importance is measured in more meaningful terms than just size. Steel Winds is the first commercial deployment of the Clipper Windpower 2.5-MW Liberty turbine, the first installation on a former Superfund site, and is said to be the largest wind farm in the U.S. developed in an urban setting. In addition, the project anchors Lackawanna’s redevelopment of a former industrial site along Lake Erie for public use.

Acquiring capacity from renewable resources is now mandatory for many electric utilities, and nowhere is green generation being pursued with more vigor than in California. Regulators there want power from renewables to account for at least 20% of utilities’ annual sales by 2010, and Governor Schwarzenegger is proposing increasing the minimum to 33% by 2020. Wind power appears to have the lowest technical risks of the renewables options, but don’t ignore the rising development risks. Here’s a primer on developing wind projects in the Golden State—and elsewhere.

Stator cooling water treatment is often ignored—until the generator fails. Proper treatment and monitoring is essential to keeping the copper in your stators, where it belongs.

During this 125th anniversary year, Retrospective has surveyed the evolution of the power industry as chronicled in POWER. The magazine’s original focus in the 1880s was to fill the fledgling industry’s technical information vacuum and share common operating experiences. Our goals today are remarkably similar, as technology continues to change and operators continue to learn […]

The electric power industry is capital-intensive, and it takes several years to build and commission a baseload plant for commercial operation. Owners seek contractors who are willing—given proper incentives—to build a plant for a lump-sum price with a guaranteed schedule and performance. Matching an owner’s wants with contractors’ needs is an exercise in allocating risk. Avoid the contract traps that can stall a project and cost millions to resolve.

POWER began its life in October 1882 as a tabloid-size publication originally entitled Steam. About the same time, two young Boston advertising salesmen decided to launch a new magazine about textile mill steam plants, called POWER. They bought Steam prior to publishing POWER’s first issue, so early issues of this magazine carried the flag “POWER, […]

During my 30-year career at the American Public Power Association (APPA), I’ve had a front-row seat for most of the major events in our industry’s recent history. So it disturbs me when my view of our history is 180 degrees out of phase with how others perceive it. Such was the case with the preamble […]

The eyes of Texas—and the rest of the world—are upon NRG Energy after its September application for licenses for two new reactors at South Texas Project (see Global Monitor). The filing was the first of its kind in nearly three decades and the first of up to 30 like it expected over the next few […]

This May, the Arizona Corporation Commission (ACC) rejected a proposal by Southern California Edison (SCE) to build Devers-Palo Verde No. 2 (DPV2)—a 230-mile-long, high-voltage transmission line connecting California and Arizona. The line, approved by the California Public Utilities Commission (CPUC) four months earlier, would enable SCE to import additional low-cost electricity from Arizona. The ACC’s rejection of DPV2 highlights a significant challenge for state and regional resource planners—weighing state interests against the regional benefits of interstate electricity commerce.

TVA’s 1,155-MW Browns Ferry Unit 1 returned to service on May 22 after sitting idle since 1985, when all three units were shut down to address management and operational concerns. Units 2 and 3 returned to service in 1991 and 1995, respectively, after extensive upgrades to controls, electrical systems, pumps, motors, and more. The return of Unit 1 began in 2002 with a five-year $1.8 billion restart plan to make all three units essentially identical, and that goal was accomplished in style. Welcome back, Unit 1.

A Luminant-Bechtel team completed replacement of four steam generators and the reactor vessel head—plus almost 200 other work packages—in a short, 55-day outage at Comanche Peak Unit 1. Matching or exceeding this schedule will become the goal for those who follow.

Detroit Edison teamed with Washington Group International to complete a first-of-its-kind nuclear retrofit project: replacing two moisture separator reheaters during a single 35-day outage with a perfect safety record. POWER recognizes this significant accomplishment by naming Fermi 2 Power Plant a 2007 Top Plant.

Just under a year ago, Omaha Public Power District completed perhaps the most complex nuclear power plant renovation in the history of the industry in a scant 85 days—five fewer days than the original plan called for. POWER recognizes Fort Calhoun Nuclear Generating Station as a Top Plant for packing more work into one outage than was thought possible, and then executing the plan ahead of schedule and below budget.

To make the most of their digital devices and enable the sharing of data by different departments, new and old plants alike need a reliable digital data infrastructure.
