Entergy Corp., the second-largest operator of nuclear power plants in the U.S., announced on Monday it will cancel its proposed spin-off transaction that would have relocated six of its nuclear units into newly formed companies, Enexus Energy Corp. and EquaGen LLC. This decision occurred in the wake of the New York Public Service Commission’s (NYPSC) decision on Thursday to reject the company’s planned spin-off.

I’m often asked about my source of ideas for this space each month. I have two primary sources of subject material. First, I read the industry news every day and save those items that either annoy or agitate me. At the end of the month, I go over the list, often a long one, and pick the one item that immediately motivates me to take virtual pen to paper. This month, no single item emerged as the topic for my bully pulpit, so I present a potpourri of loosely connected topics for your consideration. (It should be noted that other things bug other members of the editorial staff; we’re a diverse group and do not always agree about industry issues.)

UK-based Sherborne Sensors has introduced the LSI series of closed-loop gravity-referenced servo inclinometers to the North American market. The family of inclinometers is specially designed to withstand severe shock and vibration inputs for precise measurements in demanding environments. The series incorporates a unique, flexure-supported torque-balancing system that is rugged enough to withstand shock inputs of […]

Biomass has many advantages as a fuel for boilers: It’s inexpensive, readily available in many regions, CO₂ neutral, and its use warrants government subsidies. The fuel also presents unique concerns to the designers, owners, and operators of biomass plants, especially in the design of the control system.

Siemens Hands Over 870-MW Dutch Gas Plant. Siemens Energy on Feb. 12 handed over the 870-MW Sloecentrale combined-cycle power plant to the joint venture of Dutch company Delta Energy and Electricité de France. The natural gas – fired plant in the Dutch town of Vlissingen-Oost reportedly has an efficiency of 59% and uses a state-of-the-art […]

High-speed imaging systems manufacturer Photron introduced hardware to extend the normal operating temperature range of the Fastcam SA5 and Fastcam SA2 high-speed cameras. The Range Version (RV) is a new sealed case design that makes the camera models impervious to dirt, dust, and sand. Photron’s RV option includes two serviceable external fans that direct cooling […]

Nearly every combined-cycle operator recognizes that cycling reduces the life expectancy of hot-gas-path components in combustion turbines. Often overlooked, however, is that the same phenomenon affects the heat-recovery steam generator (HRSG).

Early last year, there were promising signs that electric transmission line construction would be facilitated by the convergence of the new administration’s emphasis on developing remote renewable generation resources, proposed legislative provisions expanding federal siting authority, and the granting by the Federal Energy Regulatory Commission (FERC) of generous cost-of-service returns on such investments. However, the stars did not align for transmission policy in 2009 as had been hoped, and the forecast is cloudy.

Greensburg was destroyed by an EF5 tornado on May 4, 2007. Instead of abandoning the Kansas town, the community quickly embraced the task of rebuilding it from the ground up, maximizing the use of renewable energy sources and energy efficient building techniques. Rebuilding continues, but the future of Greensburg has never been stronger.

In response to Ontario’s provincial regulatory mandates to phase out the use of coal by the end of 2014, Ontario Power Generation (OPG) is exploring its capability to employ biomass feedstocks to displace coal in some units within the OPG thermal fleet. The primary fuels employed during the respective trials at its Nanticoke and Atikokan Generating Stations have been agricultural by-products and commercial grade wood pellets. The Canadian utility has learned valuable lessons about fuel supply and logistics, and the technical challenges of safely handling and firing high levels of biomass.
