You can’t spell C-S-P without S-P-A-I-N. Though there are now many nations with concentrating solar power (CSP) plants in operation, and nations with larger ones than Spain possesses, it’s difficult to

It is true that electric motors and transformers are some of the most dependable pieces of equipment installed at power plants. They can, in many cases, withstand a high level of mistreatment while continuing

Solar power has taken off the training wheels. Once an afterthought, solar photovoltaic (PV) generation has been one of the major sources of new capacity for several years. According to statistics from the

Gas-fired power is booming—even more than expected. For only the second time ever, but also the second time this year, gas generated more electricity in a month in the U.S. than coal. According to statistics

In water-stressed regions outside the U.S., power producers and other industrial water users are incorporating higher levels of water reuse, some to the point of zero liquid discharge (ZLD), due to heightened

There’s an old saying in Washington that when everyone is upset, you’ve probably done something right. By that measure, the Environmental Protection Agency’s (EPA’s) latest update to the National

Coal pulverizers are the heart of a pulverized coal-fueled boiler. Often, the root causes of nonoptimized combustion lie with the pulverizers. Capacity; reliability; and environmental issues such as slagging

The world has a problem. According to the World Bank, 1.1 billion people lack access to any form of modern energy service, and more than double that number lack access to adequate, reliable, affordable, and

One of the world’s largest biomass-fed organic rankine cycle (ORC) plants is getting ready to begin operations. Italian firm Turboden is preparing to put online an 8-MW power unit in Athens, Maine, that will

The challenge of getting a new generation of workers interested in the power sector is one I hear about frequently. Too many young adults are more fascinated by the tech sector, plant folks say. That may be

Ethiopia’s generation capacity got an immense boost as operations began at the 1.87-GW Gibe III hydroelectric power plant in the middle reach of the Omo River basin this October. The plant—Ethiopia’s

The presence of unburned fuel in a power plant’s ash indicates an inefficient combustion process, as some of the energy in the fuel is being wasted. Unburned fuel also poses a risk to safety; if ignited, an

Battery storage firms and energy storage experts at the Energy Storage North America (ESNA) conference in San Diego Oct. 13–15 were effusive in their praise of battery storage’s potential while

GE Evaporation/Solidification System Specifically Designed for Flue Gas Desulfurization Wastewater GE’s Current Biological and Chemical Systems Also Will Meet New EPA Rules New GE Solution is Cost-Effective, Reduces Capital and Operational Expenses  ORLANDO—November 17, 2015—GE (NYSE: GE) today introduced a new evaporation/solidification technology for flue gas desulfurization (FGD) to meet the recently released U.S. Environmental […]

Turnkey solution delivers user-friendly, actionable information for business improvement LAKE FOREST, Calif. – Nov. 9, 2015 – The new Wonderware Office Bundle from Schneider Electric Software streamlines the ability to access and interpret operations data, bringing “big data” benefits to a new set of users. The solution’s easy installation and native connectivity to plant floor and […]

One of the “flexibility” measures built into the Environmental Protection Agency’s (EPA’s) final Clean Power Plan (CPP) is the option for states to join multi-state emissions trading programs for carbon dioxide. Panelists in a session focused on this issue at the National Association of Regulatory Utility Commissioners (NARUC) annual meeting in Austin largely agreed on […]

Comments made at the annual meeting of the National Association of Regulatory Utility Commissioners (NARUC) suggest that the regulatory group and the Environmental Protection Agency (EPA) have been in regular dialog throughout the process of developing the Clean Power Plan (CPP), arguably the most complex environmental regulation affecting the power generation sector and electric utilities. […]

The operation will allow the company to increase its turnover twofold in the coming five years, becoming an international leader in the gas turbine sector with an integrated business model, and expanding its markets in Europe, the Middle East and the United States Following the EU Commission approval on the 8th September 2015 of General Electric’s acquisition […]

As many coal-fired power plants designed for baseload service are asked to cycle, unforeseen stresses have been introduced to boiler pressure parts. Understanding the effects and implementing mitigation strategies could prevent premature component failure and keep facilities operating reliably. On August 3, 2015, the U.S. Environmental Protection Agency finalized the Clean Power Plan, which calls […]

Creeped out and fatigued—that’s the state of many coal-fired boilers these days. Understanding failure mechanisms and suitable testing methods for identifying potential trouble can help you find problems before the problems find you. Even as the current regulatory environment pushes new power generation to utilize natural gas over other fuel sources, a significant amount of […]

See if you can fill in the blanks: “A debate has been created after a paper was published in the BLANK Journal, suggesting the new BLANK Guidelines… are biased and based on an incomplete survey of current studies.” That quote from Digital Journal, referring to the British Medical Journal and the U.S. Dietary Guidelines, could […]

Coal dust combustion events injured employees and damaged equipment at Laramie River Station in May 2013. Any dust-filled facility could consider implementing some of the plant’s corrective actions to reduce the risk of experiencing a similar incident. When Laramie River Station (LRS), near Wheatland, Wyo., was built nearly 35 years ago, it was state-of-the-art. Constructed […]

On August 8, 2005, the Energy Policy Act of 2005 (EPAct) was signed into law. It remains, arguably, the last significant piece of energy legislation to be enacted in the U.S. The changes wrought by EPAct are far-reaching and controversial, and for the gas and electric industry, perhaps no change has been more significant than […]

Largely dependent on imported fuel oil, many island systems must grapple with soaring electricity costs and reliability issues, in part because they are isolated and they don’t benefit from economies of scale. But some nations are seeking alternatives. It’s the same story all over the world. To fuel their economies and support growing populations, geographically […]

Just as we were drafting this commentary, the U.S. Environmental Protection Agency (EPA) issued a new ground-level ozone rule, tightening the standard from 75 to 70 ppb. The projected human health and environmental benefits are substantial. Yet there has been significant concern about tightening the ozone standards because of compliance cost. As it happens, our […]

As the coal industry declines in many places around the world, can the mines it leaves behind be repurposed for cleaner energy projects that benefit multiple stakeholders, including local economies? Several existing and planned projects demonstrate that there may be multiple paths toward that transition. No question, the coal industry in Appalachia, the rest of […]

Generation III nuclear reactors have not shown much ability to overcome the weaknesses of conventional Gen-II light-water reactor technology, offering at best evolutionary approaches. Is there room for a more revolutionary approach? Many parties are exploring new technologies, but it’s impossible to tell which, if any, will succeed. Last August, Andy Revkin, The New York […]

The U.S. Department of Energy (DOE) wants GE to plan and propose a large-scale pilot test of a carbon dioxide capture solution that uses a class of amino silicone compounds used to soften hair or clothing. The

The global market for solar photovoltaic (PV) panels shows no signs of slowing down, with cumulative installed capacity expected to reach 700 GW and annual demand to pass 100 GW by 2020, according to GTM Research. This booming market has spurred manufacturers to introduce a variety of innovations intended to increase panel efficiency and reduce […]

AREVA has installed the first-ever boiling water reactor (BWR) assemblies in the U.S. that features an 11×11 fuel rod array, the French nuclear giant revealed this September. The new fuel design, the ATRIUM 11, has been used to produce power at two nuclear plants since April, though AREVA declined to name the reactors. However, the […]
