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.

China in early July installed the 32nd and final turbine of its mammoth Three Gorges Dam, virtually completing the controversial 1994-initiated hydropower project on the middle reaches of the Yangtze River.

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.

Poland, a country that currently depends on coal power for nearly 85% of its electricity and plans to build another 11,300 MW of new coal-fired capacity by 2020, suffered a critical planning setback in mid-July as the European Union (EU) effectively blocked the country from using free carbon emission permits to build new coal-fired power plants.

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.

An innovative mini-grid in April turned on the lights for about 250 residents living in Ilha Grande, a tiny island on the northwest coast of Maranhão State in northeastern Brazil.

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.

Japan’s Sumitomo Electric Industries in July began operation of a new power generation and megawatt-class storage system at its Yokohama Works site.

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.

Several major power plants around the world began operations over the past months.

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 […]

Belgian Cabinet Votes to Prolong Tihange 1 Reactor Life. Belgium’s cabinet in early July approved plans by GDF Suez subsidiary Electrabel to keep the 1975-built Tihange 1 reactor operating until 2025—almost a decade longer than planned—but it rejected a proposal to delay by a year the planned 2015 closure of Electrabel’s two 1975-built reactors at […]

(Memosens sensors are lab-calibrated devices […]

In the following case study, Aquatech International Corp. discusses a water treatment system designed to minimize water usage and waste discharges, both liquid and solid, at a gas-fired combined cycle plant in California.

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 […]

In December 1973, President Richard Nixon explained to the American people his administration’s critical initiative to confront the “energy crisis” du jour (precipitated by the 1973–74 Arab oil embargo): “Many [energy savings measures] require inconvenience and sacrifice. But daylight saving time… will mean only a minimum of inconvenience and will involve equal participation by all. […]

Success in life and business is all about seizing the right opportunities at the right time. Opportunities abound today in the electric utility business. Our industry is in the midst of an extraordinary period of transformation and investment that will affect how we produce and deliver electricity—and what customers pay for it—for decades. By 2020, […]

The 1,309-MW Claus C power plant showcases the successful repowering of an existing steam power plant by upgrading it and adding a highly efficient combined cycle plant that doubles the original plant’s power output for just a 35% increase in fuel consumption. In addition, the newly retrofitted plant is cutting CO2 emissions by 40% compared with a simple-cycle gas-fired plant of equal capacity.

The Dutch utility Eneco and the Danish energy group DONG Energy recently collaborated in building the 870-MW Enecogen Power Station that has a thermal efficiency above 59% and is designed for maximum operational flexibility. As part of Eneco’s strategy to lower emissions across its fleet, the combined cycle plant is designed to quickly compensate for intermittent power produced by the utility’s wind turbines.

Glow Energy’s 382-MW Glow Phase 5 power plant in Thailand exceeded early expectations by packing into a tightly constrained space more capacity than anyone thought possible. The plant’s engineering feat earns it recognition as a POWER Top Plant for 2012.

Omaha Public Power District (OPPD) has postponed restart of its troubled 478-MW Fort Calhoun nuclear plant for the third time since it was shut down 16 months ago. Restart of the reactor, located 19 miles north of Omaha, Neb., requires regulatory approval, and that is now tentatively anticipated early next year.

A federal district court on Thursday ruled in favor of more than 800 plaintiffs when it held the Tennessee Valley Authority (TVA) liable for the December 2008 failure of coal ash containment dikes at its Kingston Fossil plant in Roane County, Tenn., that resulted in the spill of more than a billion gallons of coal ash sludge.

Injection of carbon dioxide began last week at one of the world’s first fully integrated coal-fired carbon capture, transportation, and geologic storage projects. The "Anthropogenic Test" conducted by the Southeast Regional Carbon Sequestration Partnership (SECARB) transports carbon dioxide via a 12-mile pipeline from a 25-MW post-combustion carbon capture facility at Southern Co.’s 2,657-MW Plant Barry in Bucks, Ala., and sequesters it within a saline Paluxy Formation at the nearby Citronelle Oil Field operated by Denbury Resources.

Exelon on Tuesday said it plans to withdraw its Early Site Permit (ESP) application for construction of a new reactor at an 11,500-acre tract of land southeast of Victoria, Texas, saying “low natural gas prices and economic and market conditions . . . have made construction of new merchant nuclear power plants in competitive markets uneconomical now and for the foreseeable future.”

The U.S. Trade Representative on Monday asked the U.S. International Trade Commission (ITC) to investigate how U.S.-provided renewable energy services affect development of renewable energy projects worldwide. The ITC’s report, expected by June 28, 2013, will focus on the development, generation, and distribution of renewable energy—specifically onshore and offshore wind and solar energy.

Hurricane Isaac soaked the Gulf Coast of Louisiana and Mississippi after making landfall Tuesday night with sustained winds of up to 80 mph, leaving thousands without power in five states. On Tuesday, Entergy took its Waterford 3 nuclear plant offline as a precautionary measure.
