Nigeria brought 1.5 GW of natural gas–fired generation from three brand new power plants online in May, adding much-needed capacity to the grid. But because the West African country that is Africa’s biggest economy doesn’t have the means of transporting its abundant gas resources to its power plants, its crippling power shortages are expected to […]

What separates investor-owned utilities (IOUs) and public power companies these days? Less than you might imagine. In early June, while the Edison Electric Institute (EEI), the trade association for IOUs, was holding its annual meeting in New Orleans, I was in Minneapolis at the annual conference of the American Public Power Association (APPA), which represents […]

Despite its apparent environmental benefits and strong government backing, generating power from landfill gas hasn’t gained traction for a variety of reasons in the U.S. Will the Clean Power Plan bolster this “dirty” renewable power source?  For the U.S. Environmental Protection Agency (EPA), the only clean thing about landfills—those engineered dumps that entomb America’s infinite […]

The 1,240-MW coal-fired Mong Duong 2 power plant in Vietnam—the country’s first new private sector power plant to be commissioned in the past 10 years—began commercial operations on May 11, six months ahead of schedule (Figure 6). AES Corp. built the plant on a build-operate-transfer (BOT) basis. It has a 25-year power purchase agreement with […]

At the Tennessee Valley Authority (TVA), generation transitions are nothing new. The nation’s largest public power system—with 34 GW of generating capacity, supplying retail distributors with nine million

Australian firm Carnegie Wave Energy, operator of the Perth Wave Energy Project—the world’s first commercial-scale, grid-connected wave energy array—is on target to take its CETO technology to the next stage with a four-fold improvement on a dollar-per-MW basis, CEO Greg Allen said.

Harrington Generating Station, located near Amarillo, Texas, began burning Powder River Basin (PRB) coal when its units first entered service, beginning in 1976. A unique feature of the plant is that TUCO Inc. buys and delivers the coal and Savage Services owns and operates the plant’s coal-handling facility. Incomparable housekeeping and exceptional safety performance evidence […]

South Africa’s energy minister Tina Joemat-Pettersson has pledged urgent resolution of the nation’s worsening power crisis.

The United States is continuing its successful track record of providing global leadership in technologies critical to ensuring the prosperity of current and future generations, as it has done for decades. Today, clean energy technologies need to be quickly developed to satisfy often opposing energy needs: national security, affordability, and environmental sustainability. The nation is […]

An innovative wind turbine concept currently in the prototype phase captures the energy of vorticity, an aerodynamic effect also known as the “vortex shedding effect.” As the wind bypasses a fixed structure, its flow changes and generates a cyclical pattern of vortices. Once these forces are strong enough, the fixed structure starts oscillating, may enter […]

The global hydropower sector has seen an upsurge in development activity lately, with installed capacity growing by 27% since 2004 (Figure 2), a new report from the World Energy Council (WEC) suggests. 2. World hydropower development. Hydropower development around the world stalled from 1999 to 2005, reflecting the impact of the World Commission on Dams, […]

SaskPower, the Saskatchewan provincial utility that made history last year by developing the first full-scale post-combustion carbon capture retrofit for an operating coal-fired power plant, has taken the next step in fostering development of the technology. Its Carbon Capture Test Facility (CCTF) has officially been launched in Estevan, Saskatchewan. The June 18 launch was attended […]

What happens in Washington, D.C., seldom stays in Washington, D.C., so on April 21 at the 17th annual ELECTRIC POWER Conference & Exhibition, the Powder River Basin (PRB) Coal Users’ Group took a look at what is headed their way from the nation’s capital. The first item was, surprise, a success story, according to Rick […]

This interview with Dr. Fatih Birol, Chief Economist, Director of Global Energy Economics and Executive Director (starting September 2015), International Energy Agency (IEA) was conducted by Global Business Reports in May 2015.

This resource list is a web-only supplement to the June 2015 issue of POWER feature story on women in the power generation sector and results of our April 2015 survey of women in the power industry. Although coal and gas provide a larger percentage of U.S. electricity than nuclear, wind, or solar energy, the fossil […]

In order to achieve its goals for the future, the power sector in Turkey will need to leave the past behind. Download a pdf of this sponsored report by Global Business Reports. Power in Turkey (Global Business Reports, 2015)

Our country’s energy landscape is rapidly changing. For the first time in decades we’re producing more barrels of oil in the United States than we import from other countries, thanks in part to shale oil production. Newly developed natural gas resources have enabled the U.S. to begin transitioning from a modest net importer of natural […]

Despite plunging oil prices, 2014 was a formidable year for renewables, according to two reports released in early 2015. According to the “Global Trends in Renewable Energy Investment 2015”—the annual report prepared by the United Nations Environment Programme (UNEP), the Frankfurt School-UNEP Collaborating Centre for Climate & Sustainable Energy Finance, and Bloomberg New Energy Finance—energy investments […]

Four industry executives sometimes agreed, and sometimes disagreed, about the great unknowns concerning the Environmental Protection Agency’s Clean Power Plan during the Executive Roundtable at this year’s ELECTRIC POWER Conference & Exhibition.  What problems will the Obama administration’s upcoming Clean Power Plan (CPP) deliver to the executives who manage the companies that make the power? […]

The European Commission (EC) this April launched an extensive investigation into subsidies that 11 European governments provide to utilities to ensure future power reliability, saying it is concerned that the measures may distort competition. The sector inquiry into capacity mechanisms is the first under European Union (EU) state aid rules introduced in May 2012, which […]

The operation of an electric power generator produces large amounts of heat that must be removed to maintain efficiency. Depending on the rated capacity of the generator, it might be air-cooled

How do women in the power generation business—in power plants and in the vendor community—view their jobs in this male-dominated industry? In what is likely the first survey open to women across the industry, they told us. The November 2008 issue of POWER included an industry-first in-depth look at women in the power industry, “Workforce […]

The Environmental Protection Agency’s (EPA’s) Clean Power Plan (CPP) is feasible in its ultimate goals, but getting there will take a lot of work and some rethinking of how the targets are achieved

Steam production is strongly influenced by the cleanliness of the gas-side heat transfer surface in a heat recovery steam generator (HRSG). However, when deposits begin to impede heat transfer or increase gas-side pressure drop, it is time for a cleaning. CO2 pellet blasting is a cost-effective and environmentally benign cleaning method available to power plant […]
