Gazprom on Sept. 1 made the first weld of a 4,000-km natural gas pipeline that will run from gas production centers in Russia’s Yakutia and Irkutsk gas production fields to Russia’s Far Eastern regions

Mitsubishi Heavy Industries (MHI) in August revealed that it had developed a 2-MW 16-cylinder high-speed gas engine that potentially offers a power generation efficiency (lower heating value) of more than

A sustained Arctic blast composed of freezing rain, record snowfalls, and high winds hit 22 states, from Mexico to New England in early February 2011. The extreme weather severely affected the power generation

Regulators from six states shared starkly different views on the Environmental Protection Agency’s (EPA’s) proposed carbon rules for existing power plants at a House hearing on Tuesday. Some state-level officials said the EPA’s overall emission targets and suggested means to achieve them are based on unworkable and unrealistic assumptions about how state and regional power […]

The U.S. added 1,146 MW of utility-scale solar generation in the first half of 2014—the most ever for a first- and second-quarter period—but natural gas continued to lead new additions, though its margin may be shrinking, according to Energy Information Administration (EIA) data. Through the first six months of 2014, the U.S. added 2,179 MW […]

They call themselves “Fractivists.” Environmental and community activists fearful of relatively new natural gas and oil drilling technologies that have transformed the U.S. energy economy have launched a high-profile, highly hyped campaign to shut down new natural gas production. But their prospects of success look dodgy. Ground Zero in the debate over fracking—shorthand for the […]

Nearly four years to the day after eight people were killed in a natural gas pipeline explosion in San Bruno, two judges of the California Public Utilities Commission (CPUC) ruled on Sept. 2 that Pacific Gas & Electric (PG&E) must pay a record $1.4 billion in fines and penalties for its role in the disaster. […]

The Aug. 4–6 U.S.-Africa Leaders Summit shed light on the power plights faced by sub-Saharan African countries, but it also highlighted their massive power potential and the array of solutions under consideration to resolve Africa’s energy crisis. Here are a number of key insights gleaned from discussions at the summit—the first a U.S. president has […]

For a country focused on wooing big businesses, constructing large industrial complexes, and building new administration offices, having a reliable electricity supply is vital. But with few natural resources, flexible and efficient generation is imperative. Korea Southern Power Co. (KOSPO) CEO Lee Sang Ho has a vision of making KOSPO into a “global top 10 […]

Awash in a sea of wind turbines, California’s Coachella Valley needed reliable peaking generation to back up its intermittent wind power. Competitive Power Ventures answered the call with the eight-unit, 800-MW Sentinel plant. Driving west on Interstate 10 through the Mojave Desert in California is a mostly monotonous experience of sand, scrub brush, and rolling, […]

The Municipal Government of Beijing through its operating companies is making enormous investment into its power and energy infrastructure, particularly combined heat and power facilities and renewable energy projects. The latest addition to its fleet of plants is the Jingqiao Power Plant, which supplies electricity to the Beijing grid and steam heat to nearby commercial […]

NYU needed to repower its decades-old cogeneration system and cut emissions at its main campus in Lower Manhattan. The new gas turbine–based system cut the university’s energy bills by $5 million a year—and kept it going when Hurricane Sandy walloped the East Coast.  When figuring the payback period on a new power plant, calculations are […]

With a huge gold mine set to increase the load on an already overstressed grid, the mine owners and a Dominican generation company found a way to power mine operations and address capacity shortfalls by joining forces on the same project.  Like many countries in the developing world, the Dominican Republic regularly struggles to meet […]

Combined cycle plants have the advantages of being extremely efficient and can be built in two phases when power needs peak unexpectedly. Ulsan 4 was built in response to the country’s 2011 power crisis for both reasons. The first task was installation of the combustion turbines in time to meet the 2013 summer peak demand. […]

Once merely a staple of backup and distributed generation, reciprocating engines are now challenging other resources for utility-scale generation—in addition to carving out some new niches. Grant County is a rural, sparsely populated county in southwestern Kansas. It doesn’t have a lot of people—its population in the 2010 U.S. Census was just 7,829—but what it […]

EU Doles Out €1 Billion in Funding for Renewable Projects Under NER 300. The European Commission on July 10 awarded €1 billion ($1.34 billion) to 19 renewable energy projects and a carbon capture and storage (CCS) project under its NER 300 program. The projects will cumulatively raise European Union (EU) renewable energy production by about […]

Calpine Corp. has its hands in two deals with large power companies—selling a plant to Duke Energy in Florida while buying a plant from Exelon Corp. in Massachusetts. On Aug. 25, Calpine announced that it has agreed to buy Exelon’s 809-MW Fore River Generating Station, which is located about 12 miles southeast of Boston, for […]

Geographically and politically, Texas and Germany are on opposite sides of the world, but both believe strongly in competitive energy markets, and both have largely deregulated their power industries. Now both are reconsidering their market designs. Its easy to think that Germany and Texas could not be more different. One is northern, cold, and Old […]

Dynegy Inc.—the Houston-based power company with operations in the Midwestern, Northeastern, and Western U.S.—has signed two separate agreements to acquire generation assets from Duke Energy and Energy Capital Partners (ECP). The acquisition includes a total of 12,313 MW of coal and gas generation, which will increase the company’s total portfolio to nearly 26 GW. Dynegy […]

Europe’s third-largest power provider last week revealed it may be forced to shut down more conventional power plants compromising a total of 1 GW and terminate 470 MW in supply contracts if market conditions in Germany do not improve.  RWE has blamed “political intervention” for “making [its] business challenging”—and specifically, the subsidized expansion of renewables […]

Long viewed as a potential “next big thing” for power generation—often drawing unwarranted hyperbole in the process—and more recently as niche distributed generation, fuel cells are finally beginning to make some noise at grid scale. Hydrogen- and natural gas–powered fuel cells have been deployed over the past decade in behind-the-meter and microgrid applications for on-site […]

The Tennessee Valley Authority (TVA) is poised to decide on the fate of a coal-fired power plant in Tennessee.  At its next meeting on Aug. 21, the TVA board will likely choose to retire three existing coal-fired units at the Allen Fossil Plant in Shelby County, Tenn., by December 2018 and replace them with a […]

NRG Energy is the latest company in a string of generators choosing to cease burning coal at generating units to comply with environmental rules.   An environmental action plan to reduce air pollution in Illinois released by the New Jersey–based company on Aug. 7 proposes to retire the 251-MW coal-fired Unit 3 at the 761-MW […]

With three recent requests to the Federal Energy Regulatory Commission (FERC), the Environmental Protection Agency (EPA) has signaled it may seek to slow the recent drive to export liquefied natural gas (LNG). Three times this year, the Texas regional office of the EPA has asked FERC to consider wider impacts of increased greenhouse gas emissions […]

This supplement to “Strategies for Inspecting HRSGs in Two-Shift and Low- Load Service” in the August issue includes additional discussion of the heat recovery steam generator (HRSG) Inspectors Toolkit and HRSG Inspection Guide sections of the main article plus additional photos of damage caused by rapid startups and two-shifting of units over time. More Tools […]

A combination of falling natural gas prices, greater integration of renewable generation, and advancing technology has meant changing roles for many plants, particularly gas turbine combined cycle plants. (See “Managing the Changing Profile of a Combined Cycle Plant” in the June 2014 issue.) The added wear and tear on plant equipment, and the changing maintenance […]
