The article offers information on maintaining energy plant water sample panels. Many new plants are stated to start off by establishing maintenance schedules for sample panels and training operators in their use and maintenance procedures. The schedules are found to get abandoned in commercial operation because keeping air-quality analyzers, instrumentation and control systems on-line is given priority. Two case studies are presented to illustrate the importance of sample panels to water chemistry analysis. In both the studies the monitoring problems resulted in a forced outage or steam cycle damage. It is stated that the wet tests conducted by many plants do little to protect equipment. It is suggested to ensure analyzer accuracy and standardization for accuracy and reliability.

The article reports on the development of Clean Energy Systems Inc. (CES) of a zero-emissions demonstration plant. It is noted that CES has developed a zero-emissions power generation technology by incorporating a component proven in the aerospace industry with conventional power plant equipment. The CES process employs an oxy-combustor that generates steam by burning gaseous fuel in the presence of gaseous water and oxygen. This fuel is prepared by processing conventional fossil fuel such as refinery residues, biomass or biodigester gas, coal-derived syngas, or natural or landfill gas.

The article discusses various issues related to energy development. The Federal Energy Regulatory Commission (FERC) has approved 82 of the initial set of 87 mandatory system reliability standards developed by the North American Electric Reliability Council. The FERC is likely to enforce the reliability standards from June 1, 2007, failing which power companies may face heavy penalties. The article also discusses the widespread use of hydroelectricity in Colombia. Colombia gets 76 percent of its electricity from hydro plants. Thermal plants fueled by coal and natural gas are used to fill shortfalls in supply during the dry season.

The article focuses on the Coca-Cola/Mas Energy Trigeneration Facility in Atlanta, Georgia, the first U.S. operational trigeneration project which uses treated landfill gas as an energy source for its operations. The renewable energy facility uses a trigeneration or CCHP (combined cooling, heat, and power) system and generates at least 48 million kWh of on-site renewable energy every year. It is operated by Mas Energy LLC and allows Coca-Cola Co. to level its energy costs in a long term.

The article explores the operation at Entergy Corp.'s Performance Monitoring and Diagnostic Center (PM&DC) in the U.S. The most remarkable feature of the facility is the implementation of the Operations Information System (OIS) to improve operations. It assures early identification of changes in equipment physical, thermal, operational and environmental performance, improved ability to mitigate degrading equipment condition and unite performance and maximize unit value. The facility also employs the most reliable people and has enhanced teamwork capable of leveraging expertise and technology.

The article explores the operation at Entergy Corp.'s Performance Monitoring and Diagnostic Center (PM&DC) in the U.S. The most remarkable feature of the facility is the implementation of the Operations Information System (OIS) to improve operations.

It assures early identification of changes in equipment physical, thermal, operational and environmental performance, improved ability to mitigate degrading equipment condition and unite performance and maximize unit value. The facility also employs the most reliable people and has enhanced teamwork capable of leveraging expertise and technology.

The article reports that Tennessee Valley Authority's (TVA) Shawnee Fossil Plant has been able to build up a strong and good reputation for itself. The plant has allegedly been known for its timely completion way back more than 50 years ago. It has also generated worth 9.4 million of megawatts per hour (MWh), while ranking in the top 25 percent of plants nationwide for lowest cost of production. It has likewise won the national continuous operating title won by its Unit 6: 1,093 days, 11 hours, and 24 minutes when it went off-line on February 15, 2007. In addition to these recognitions, the plant has also been routinely ranking in the top 10 percent nationally for availability and reliability.

The article talks about building and operations undertaken for the automation of U.S. electric power plants. Accordingly, the Nuclear Regulatory Commission (NRC) has stated that it planned to hire hundreds of experienced nuclear engineers and convince them with very attractive salaries and benefits because the commission was afraid that it would not be able to cope both with the expected flood of combined construction and operating license applications and routine tasks. It has noted that under the case of NRC, its 2007 federal budget includes not only funds for expanding its staff but also inducements and subsidies for the first next-generation nuclear plants stipulated in the 2005 Energy Policy Act.

The article reports that U.S. Senator Ted Kennedy is opposing the Cape Wind project that is expected to produce pollution-free and renewable energy. The Massachusetts Energy Facility Sitting Board says that the project will lower local residents' sky-high electricity bills while providing 75 percent of their power needs. Cape Wind also is predicted to create between 600 and 1,000 jobs in the region and spur tourism, with negligible impact on local ecosystems. Many of his prosperous neighbors are equally alarmed. They have raised about $7 million to oppose the project. A provision in the Coast Guard and Maritime Transportation Act of 2006 gives the governor of Massachusetts right to veto the Cape Wind project despite a finding by the Coast Guard that the project would not harm navigation. It could cripple offshore wind power development.
