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.
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.
Chauncey Starr, founder of EPRI—the Electric Power Research Institute—and its first CEO, passed away on April 17, 2007. The previous day, a celebration of his recent 95th birthday had been held at EPRI, where Chauncey held forth for more than an hour on his life experiences and lessons learned. He was in fine fettle. Chauncey […]

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 […]
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.
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.
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’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 […]
