Australia in July became the first nation to abolish a price on carbon, after the Senate passed the Abbott government’s repeal bills by a vote of 39–32. Yet the country’s carbon conundrum continues because Prime Minister Tony Abbott must still get his Direct Action Plan, a proposed replacement for the country’s emissions trading scheme, to […]

While several methods exist for sizing collector pipes on steam lines, the results obtained from the various approaches can be quite different. This article will show how design parameters can be used to calculate the dimensions much more accurately. In the steam lines of thermal and nuclear power plants, condensed steam is usually discharged from […]

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 […]

Geothermal generation is clean, renewable, and cost-effective over the long term, and the U.S. has vast untapped geothermal resources. So why is it still operating on the sidelines?   For the U.S. geothermal energy industry, 2013 ended on a positive note. Cyrq Energy’s Dale Burgett geothermal plant, a 4-MW unit in southwest New Mexico, began […]

Since March, Hong Kong has been contemplating two options as it prepares to phase out its coal-fired power plants—which currently produce more than half of its electricity—to improve an enduring local and regional air quality and visibility crisis. One option calls for buying more power from coal-heavy mainland China, and the other is to increase […]

To ensure that its nuclear plants do not meet the same fate as those damaged and destroyed by the March 2011 events at the Fukushima Daiichi plant—should they be hit by similarly severe natural disasters—Tennessee Valley Authority (TVA) is using multiple new approaches to enhance safety. First Installation of New Spent Fuel Pool Instrumentation Spent […]

The world’s nuclear power generation capacity is slated to grow between 17% and 94% through 2030, the International Atomic Energy Agency (IAEA) forecasts in its 2013 Annual Report, released this July. However, it notes, those figures are slightly lower than projections made in 2012, owing to the continuing impact of the Fukushima Daiichi accident, the […]

Skilled maintenance and service teams inspect critical infrastructure, perform preventive maintenance, and quickly respond to issues to keep service levels high. It is critical that such teams work with as-built drawings that reflect original plans along with the cumulative changes. Armed with the current drawings, service teams can avoid surprises. The challenge is that drawings […]

Despite stagnant economic growth globally, primary energy consumption surged in 2013, with growth for nuclear power and renewables in power generation expanding at above-average rates, BP said in its recently released Statistical Review of World Energy 2014. According to the report, world power generation grew 2.5% in 2013, slightly up over 2012 (which saw 2.2% […]

Commissioning of all 18 generating units at China’s 13.9-GW Xiluodu Hydropower Station has been completed, making it the world’s third-largest hydroelectric project (Figure 5), China Three Gorges Corp. announced in early July. 5. Hydropower giant. Commissioning of all 18 generating units at China’s 13.9-GW Xiluodu Hydropower Station has been completed, making it the world’s third-largest […]

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, […]

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 significant reform of Germany’s aggressive renewable energy laws passed its final hurdle on July 11, setting the country on a more market-based path toward future growth. The bill was developed and approved by Chancellor Angela Merkel’s coalition government of Social Democrats and Christian Democrats. Because they are the two largest parties, the legislation was […]

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 […]

The era of Big Solar has arrived, and at the moment there are none bigger than Ivanpah. For overcoming numerous obstacles to build the world’s largest solar thermal plant, the Ivanpah Solar Electric Generating System is awarded POWER’s 2014 Plant of the Year Award. When the 392-MW Ivanpah Solar Electric Generating System in Nipton, Calif., […]

The utility-scale solar market is rapidly growing in North America, representing a large area of opportunity for project and product developers alike. The market more than doubled in size between 2012 and 2013

Problematic power plant systems diminish availability and directly affect plant productivity and efficiency. In order to maintain availability, electrical testing and maintenance services are imperative. Two

S. Korea Extends Renewables Target Deadline. South Korea’s government on June 9 said it would push back the target for mandatory use of renewable energy by two years to ease requirements for the

France will cap its nuclear power capacity at the current 63.2 GW, forcing closures if new reactors come online, and instead boost renewable generation if a bill unveiled by its energy ministry in mid-June

The 2014 POWER Plant of the Year makes history, both as a project and as our cover story. The Plant of the Year award goes to the most interesting, usually new, plant in the previous year. Sometimes it’s a
