  • NYPA Astoria Project, Astoria, New York

    New York City has an insatiable appetite for power, but supplying that power from plants inside the city’s five boroughs (where 80% of its peak demand must come from) is tough. So it’s nothing short of miraculous that a 500-MW combined-cycle plant in Astoria, Queens, began commercial operation at the end of 2005. What did it take to bring this plant on-line? The largest state-owned power organization in the U.S.—The New York Power Authority.

  • Profiling your plant engineering staff

    The latest benchmarking study by the EUCG examines the engineering and technical staffing of 62 plants, 92% of which burn coal. If you benchmark your units, plants, or fleet, the results may raise some eyebrows. But they also may help justify your plea for more intellectual capital during the upcoming budgeting cycle. Though the detailed results of the study are proprietary to EUCG member companies that participated in it, POWER was given access to the complete findings. If you want details at the plant/unit level, you’ll have to join the EUCG and participate in the study, which is ongoing.

  • Saguaro Solar Power Plant, Red Rock, Arizona

    We tend to forget that today’s super-sized power plant designs began life as small prototypes that grew in size only as fast as technology and economics allowed. Arizona Public Service, a long-time leader in solar energy development, has invested in the development of one such technology that is compatible with the sunny Southwest and certain to become more cost-competitive in the near future. This successful demonstration of a 1-MW concentrated solar power, trough-style energy system is the first to have put power on the grid since 1988. But it certainly won’t be the last.

  • Improving the reliability of turbine lube oil supply

    Five years ago, San Onofre Nuclear Generating Station’s Unit 3 turbine experienced substantial damage after the supply of oil to its bearings failed. Because the turbine coasted down without oil after it tripped, its bearings, journals, and steam path needed extensive repairs. A follow-up investigation revealed lube oil system vulnerabilities that were subsequently corrected. The lessons learned might also improve your turbine-generators’ lube oil reliability, saving you many millions in lost revenues.
