A new, mile-long submarine transmission cable in Pearl Harbor (Figure 3, p. 10) will facilitate the U.S. Navy’s plan to renovate and expand historic Ford Island. Honolulu-based Hawaiian Electric Co. Inc. (HECO) recently laid two new 46-kV lines beneath the bridge connecting the island to Oahu. The trickiest part of the installation was avoiding the […]

Focus on O&M

I couldn’t help but marvel at the synchronicity of two unrelated events over the past few weeks. The first, on January 12, was the rare cancellation of a major military acquisition program with problems called "too expensive to fix." It takes an Act of Congress to kill most military contracts due to the pork flowing […]

Competition in power generation fosters technical innovation, cleaner power plants, and downward pressure on prices. Before the 1980s, such competition was almost nonexistent: vertically integrated utilities built and operated the vast majority of U.S. plants with oversight by state regulators. The Public Utility Regulatory Policies Act of 1978 and the Energy Policy Act of 1992 […]

The 130-MW Yuncán  hydroelectric plant (Figure 4) has come online in Peru about 210 miles northeast of Lima. To show his support for the project, Peruvian President Alejandro Toledo Manrique attended the inauguration ceremony. Yuncán  was commissioned just 21 months after the Peruvian government awarded a 30-year contract to operate the plant to EnerSur, the […]

The long-awaited 41st edition of Babcock & Wilcox Co.’s (B&W’s) Steam: Its Generation and Use (Figure 5) is now available for ordering on the company’s web site, www.babcock.com. The release of the book is worth noting by power plant engineers for two reasons: The tome is the world’s longest continually published (since 1875) engineering text, […]

CFB refractory repair; Upgrading conductivity monitoring; Low-cost maintenance of spinning reserve

The 35th birthday of the Environmental Protection Agency (EPA) passed last December 2 with little fanfare. EPA Administrator Stephen L. Johnson noted at the time that, "Over the last three and a half decades, through the use of innovative and collaborative approaches to environmental protection and a commitment to responsible stewardship, we have made remarkable […]

  The U.S. needs to add 600 to 800 billion cubic feet (Bcf) of natural gas storage capacity ASAP. Independent storage providers (ISPs) are the entities best equipped to build this needed infrastructure, but they continue to be restrained by anachronistic regulatory policies. The Federal Energy Regulatory Commission’s (FERC’s) December 2005 rule-making to modify its […]

GE Energy’s latest "first" is in Turkey, where the Frame 6C gas turbine-generator—a younger cousin of the popular Frame 6B—has made its commercial debut. The turnkey 130-MW combined-cycle plant, called the GE206C, comprises two 40-MW Frame 6Cs, one GE steam turbine-generator, two heat-recovery steam generators, and a distributed control system. The gas-fired plant (Figure 1), […]
