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 […]

In our second annual report on the state and future of the U.S. power generation industry, we combine the considerable experience of POWER’s editorial staff with the market savvy of Industrial Info Resources Inc. (see next story) to preview the industry’s direction in 2008. We anticipate that the specter of carbon control legislation will hobble coal and make renewables the hot ticket while nukes continue to inch forward in a generation market that is basically treading water.

The biggest problem facing industrial managers is ensuring that they’ll continue to have a skilled workforce. With so many people nearing retirement, organizational skills are at risk, which poses a direct threat to operations. Many companies are making big investments to capture the unique knowledge and experience of graybeards before they move on. But that is just one aspect of a far more complex issue.

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 […]

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.

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 […]

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.

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, […]

October 1886 In the late 19th century, efficient combustion of solid fuels was achieved more by trial and error than by a fundamental understanding of stoichiometry and staged combustion. Boiler manufacturers took many different approaches to the challenge. Some made sense; others didn’t. In which category does the design described below fall? In 1886 the […]

Ongoing research into experience with plant- and fleet-level software reveals that these applications work side by side but do not necessarily function as an integrated “knowledge management” system. On the supplier side, the industry continues to be fragmented, with individual programs governing a narrow part of the overall plant.

The intended use is the primary consideration (even fuel is secondary) when choosing an on-site energy system. Whether the need is for power alone or for heat as well, distributed generation plants have delivered lower energy costs and improved reliability to industrial and commercial customers worldwide. Following are six case studies of reciprocating engine systems that highlight their versatility.

It took Westar Energy eight years to upgrade the Lawrence Energy Center to burn Powder River Basin coal. Its zero lost-time accident record during the million-man-hour project is a testament to Westar’s commitment to workplace safety. Here’s your backstage pass to meet the PRB Coal Users’ Group 2006 Plant of the Year.

When injuries or accidents occur, the employer ultimately loses on two counts: increased medical costs and employee absences. A policy of "safety, compliance, and then production" is more than just good business; it’s also good stewardship of the health and safety of employees who deserve no less.

Last month, POWER weighed the pros and cons of the various grid interconnection options available to distributed generation plants. This month we explore the technology choices for generating reactive power, or volt-amperes reactive (VARs), which utilities are willing to pay for as an ancillary service.

T&D systems with embedded intelligence have a great future, and they always will. Too many powerful forces—politics, money, and power—remain to be reconciled before consumers and utilities can work together, seamlessly, to reduce electricity demand and eliminate delivery system bottlenecks.

  State policy makers are characteristically reluctant to recognize that they have advanced a policy as far as they can, and that they must cede some control to fully realize its ultimate benefits. Ceding control often runs counter to policy makers’ political instinct to serve their constituents. Doing so is even harder when a new […]

This month we officially commemorate the 125th anniversary of the magazine that has been essential reading for owners and operators of power generating plants. As you read this brief history, you’ll see that—although we’re looking back at an illustrious past—the secret of POWER’s success has been its commitment to the future. As we look forward to the next milestone anniversary, we anticipate covering the latest developments in a new generation of power technologies. As always, our mission is to provide the best information and advice in the service of safely and efficiently powering the global energy industry.

Transporting large quantities of electric power over long distances via superconducting DC cables was first considered more than 40 years ago by two IBM scientists. With the recent advent of long-length commercial high-temperature superconductors (HTSCs) and the desire to move the U.S. to a hydrogen-based economy, SuperCables could revolutionize the marketing of electricity. Using HTSCs cooled by hydrogen, a SuperCable could simultaneously deliver electricity and hydrogen to end users for domestic and industrial consumption and to power fuel cell cars.

May 1885 POWER reported on the latest Twist Automatic Engine (Figure 1) in its cover story for the May 1885 issue. The editor explained that "each end of the cylinder has one main valve, for admission and exhaust, and one cut-off valve; all being plugs with partial rotary movement; and the cut-off valves being within […]

  This month’s issue of POWER commemorates 125 years of continuous publishing for the power generation business. The anniversary gives us all a chance to assess where we’ve been and where we’re going as a publication and as an industry. As power industry professionals, we all know the value of a rearview mirror—of remembering lessons […]
