Set to begin commercial operation on Sept. 17, 2012, the 280-MW Lodi Energy Center is the first “fast-start” combined cycle power plant in the U.S. The advantages of the gas turbine’s shorter startup capabilities are reduced fuel costs, lower emissions, and the versatility to effectively partner with intermittent renewable energy sources. The new power plant is located next to the city of Lodi’s municipal wastewater treatment plant and uses its treated wastewater for cooling purposes.

As part of the University of Iowa Research Park’s efforts to promote renewable energy use, the new campus power plant’s engine generators are designed to operate primarily on landfill gas when the pipeline from the Iowa City Landfill is completed, with natural gas as a secondary fuel source. To make it more efficient, the plant’s waste heat recovery system captures waste heat from the gas engine generator’s cooling and exhaust systems to produce hot water for heating, or chilled water for cooling, campus facilities.

The electric power industry is a large water user and is dependent upon reliable water supplies. Adopting new water-conserving technologies for power production can help alleviate the impact of future water shortages. Several water use reduction technologies are available, each with different benefits and costs.

Droughts, unreliable gas imports, and protests against proposed projects have hampered the Chilean power sector and its largest economic driver, the copper-mining industry. Recent policies designed to foster more reliable supplies are a move in the right direction, but remaining obstacles are formidable.

The natural gas and electricity industries have entered into an increasingly codependent relationship as coal-fired electricity gives way to natural gas–fired generation. Both industries are firmly committed to providing reliable service, although each goes about its business in different ways. Utilities, regulators, and stakeholders are searching for ways to align interests and expectations.

Plentiful supplies of low-cost natural gas have changed unit dispatch orders across the U.S., led to thermal stress–induced maintenance issues at cycling coal plants, and resulted in management challenges at coal and gas units alike. This scenario is unlikely to change so long as gas holds its competitive edge over coal.

In much of the developing world, two essentials are often in short supply: potable water and reliable electricity. Some countries have invested heavily in desalination and combined cycle technologies to simultaneously solve both problems.

Thompson Pump’s new Compact pump series has all the benefits of the popular Thompson Pump JSC series but is lighter, has fewer parts, needs less maintenance, and has a lower price. The Thompson Compact pump is 35% smaller and 20% lighter but offers the same performance as a standard size pump with 24-hour run time […]

Endress+Hauser introduced the Liquiline CM44 Series, multichannel transmitter models for monitoring and controlling processes in water, wastewater, chemical, power, and other industries. CM44 models accept inputs from up to eight Endress+Hauser Memosens digital analytical sensors, including nitrate, spectral absorption coefficient, pH, ORP, conductivity, oxygen, turbidity, and ion selective electrode sensors. (Memosens sensors are lab-calibrated devices […]

Dust Control Technology launched a family of tower mounts for the company’s atomized misting equipment, which extends droplet hang time and range while providing more precise aiming capability during slag-handling, aggregate-progressing, recycling, and coal-handling operations. Complementing a product line that already includes wheeled carriages and skid mounts, by delivering millions of 50- to 200-micron droplets […]
