From issuance of the final Clean Power Plan to mammoth mergers, 2015 will be remembered as a tumultuous year. Twelve months ago, as folks were emerging from an eventful 2014, POWER made some bold predictions, including that fuel economics will drive 2015 U.S. power markets, and the labor crunch will complicate the gas turbine arms […]

POWER‘s monthly infographic sheds light on power sector trends globally, and in 2015, it highlighted changes in plant retirements, sector revenues, rule costs, workforce, emissions technologies, and electricity costs, among other subjects. January 2015: Baseload Retirements How coal plant retirements compare with retirements of other baseload generation sources. February 2015: Power Revenues How revenues for fossil power […]

Coal ash utilization, which had stalled between 2009 and 2013 as the Environmental Protection Agency (EPA) prepared a final federal coal ash rule, increased significantly in 2014. According to the American Coal Ash Association’s (ACAA’s) most recent “Production and Use Survey,” 62.4 million tons of coal combustion products were beneficially used in 2014—up from 51.4 […]

New rules from the Environmental Protection Agency (EPA) have several unintended consequences for the power sector, an expert said at a POWER magazine event on Dec. 7. Floyd Self, an attorney with Florida-based law firm Berger Singerman, said that the bevy of new EPA rules have helped forged mergers between electric and gas utilities and necessitated […]

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

Ultrasonic testing (UT) has long been a key method for detecting defects and service-induced degradation in nuclear and fossil plant components and for supporting remaining component life assessment. But it

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

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

Siemens, the only provider of direct-current (DC) offshore wind connection projects, in October unveiled a potentially game-changing technology that it says enables cheaper and simpler grid connection of wind

GE Completes Alstom Acquisition. GE announced on Nov. 2 that a $10.6 billion deal to acquire Alstom ’s power and grid business is complete. Alstom will now entirely refocus its activities on rail transport

The UK has canceled its flagship £1 billion ($1.5 billion) competition to help commercialize carbon capture and storage (CCS) technology from power plants. The decision by the Department of Energy and Climate Change (DECC) was announced in a three-sentence release to the London Stock Exchange just days before crucial climate change negotiations are due to […]

Italian energy giant Ansaldo Energia says its acquisition of Alstom’s GT 26 and GT36 gas turbine assets and technology, as required by European regulators, will allow the company to increase its turnover twofold in the coming five years. The firm owned 44.8% by Italian state-owned holding company Fondo Strategico Italiano and 40% by Chinese equipment […]

Following regulatory approval of a $10.6 billion transaction in over 20 countries and regions, GE’s acquisition of Alstom’s energy activities is now complete. GE and Alstom sealed the deal first proposed in early 2014 with the signing of a 1,500-page “master agreement.” GE had initially proposed buying Alstom’s lucrative business for €12.35 billion, but following […]

Once again, a first-of-a-kind technology at a coal-fired power plant that is designed to reduce its greenhouse gas footprint has run into design, operational, and cost problems. This time, it’s Saskatchewan, Canada utility SaskPower’s Boundary Dam Carbon Capture project that’s facing scrutiny. (Earlier this week, an overdue precombustion carbon capture project, Mississippi Power’s Kemper County […]

Mississippi Power has revealed a new cost increase of $110 million for its Kemper County integrated gasification combined cycle (IGCC) facility. But, the company said that it has tested one of two gasification units—reaching what it says is the project's "most significant milestone yet"—and that it does not expect any new delays. Testing the gasifiers […]

The U.S. Senate has approved the Cybersecurity Information Sharing Act (CISA), controversial legislation intended to block the deluge of cyberattacks by opening up communication channels between the private sector and federal agencies.   Senate Bill 754 introduced in March by Sen. Richard Burr (R-N.C.) and co-sponsored by Dianne Feinstein (D-Calif.) passed the Senate by a […]

The ETH spin-off company Climeworks AG has announced plans to construct and operate an industrial scale CO2 capture plant to be operational by mid-2016. The Oct. 21 announcement said the plant in Hinwil (Canton of Zurich, Switzerland) “has the capacity to capture 900 tons of CO2 from the atmosphere per year.” For comparison, The Carbon […]

Battery storage has emerged from the fringes of the power sector to challenge both industry conventions and traditional generation. Where it goes from here, however—the future of battery storage technology—is a matter of some debate. Both storage firms and energy storage experts at the Energy Storage North America (ESNA) conference in San Diego Oct. 13-15 […]

Alberta-based Carbon Engineering is inaugurating a pilot project today in Squamish, British Columbia, that will capture carbon dioxide (CO2) directly from the atmosphere. The company, funded by private investors, including Microsoft founder Bill Gates and oil sands financier Murray Edwards, has developed technology based on research conducted by Harvard University–based Professor David Keith’s research groups […]

Though newer distributed generation options like microturbines, solar, and batteries have grabbed the headlines, diesel remains the go-to option because of its established technology and reliability. But growing competition and new regulations are threatening its traditional role. Here’s what diesel is doing to stay relevant. If you pay attention to nothing but the headlines in […]

Utility-scale energy storage in the form of pumped water storage has a long history. One of the oldest U.S. plants found itself in need of an upgrade after 40 years of service. Having the right equipment for the job is proving to be essential. With the current power market challenges and increasing amounts of variable […]

In its latest effort to ram down carbon emissions and address air pollution, China will strictly limit public financing to coal and other high-carbon projects and begin a national program in 2017 to cap and trade greenhouse gas emissions.  The country’s emission trading system will cover power generation, steel, cement, and other key sectors. China […]

In presentations to the Federal Energy Regulatory Commission (FERC), the nation’s regional transmission organizations (RTOs) and independent system operators (ISOs) on Sept. 17 outlined measures they are taking to prevent issues if faced with extreme weather this winter.  The measures are to prevent widespread generation outages as occurred during the Jan. 6–7, 2014, polar vortex.
