In July 2016, the German parliament approved three major pieces of legislation specifically laying out the future of the celebrated Energiewende: the 2017 revision of the Renewable Energy Sources Act, the Electricity Market Act, and the Act on the Digitization of the Energy Transition. “These three pieces of legislation will ensure that the transition of […]

This September, Puerto Rico suffered an island-wide blackout that left 1.5 million utility customers without power for more than 50 hours and reportedly resulted in multimillion-dollar losses for its already troubled economy. The blackout in the U.S. territory with a population of about 3.5 million occurred on September 21, when a blaze erupted in a […]

A magnetic level gage may be an excellent addition to a power plant boiler’s drum-level instrumentation. However, before any changes are made, owners must first understand the specific minimum requirements for water level instrumentation defined by the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code. The code requires a functional water gage […]

The dangers of the U.S.’s failing infrastructure have united both major political parties in calling for substantial capital investments to shore up safety and reliability. In California, the tragic explosion of the gas pipeline in San Bruno and the massive methane leak from the gas storage wells at Aliso Canyon have highlighted the potential for […]

Owner/operator: Rosenergoatom Fast-neutron reactors are pivotal to Russia’s ambitious nuclear power plans. The successful construction, grid-connection, and testing of the country’s first BN-800 reactor at its Beloyarsk nuclear plant is a major achievement in the right direction. Since the Soviet Union began its first experimental nuclear power projects in the 1940s, Russia has embraced nuclear’s […]

China is on an epic build-out of its nuclear generating capacity, and developing indigenous expertise and technology is central to that goal. The first completed plant leveraging the nation’s CPR-1000 design

Owner/operator: Exelon Generation and PSEG Nuclear/Exelon Generation When decision-makers choose to increase the maximum output of a nuclear power plant through an uprate, it sets in motion a process that can take many years and countless man-hours to complete. The success of Peach Bottom station’s extended power uprate project shows that all the long hours […]

Circulating fluidized bed (CFB) technology is taking a growing share of the international coal-fired power generation market, particularly in the Pacific Rim and China. Indigenous designs are also growing in

Compliance with one of the latest federal environmental regulations, the Effluent Limitations Guidelines (ELG), can be both costly and complicated. A newly available option offers features and capabilities that may make it a more attractive alternative than conventional approaches. In September 2015, the U.S. Environmental Protection Agency (EPA) finalized a new rule affecting flue gas […]

To power generation professionals, the word “cavitation” typically has negative connotations, but a new process offers a way to control this normally destructive effect and deploy it as a cost-effective life-extension technique. As operators of commercial nuclear energy facilities consider subsequent license renewals and life extensions, finding new ways to safely maintain reactor components remains […]

China, which continues to build more new coal plants than any other nation, is also on the forefront of deploying the most advanced coal plant technologies. However, these advanced units could face

As installed capacity in the U.S. continues its breakneck growth, the solar photovoltaic sector is poised for another leap forward with a variety of new technologies—if increasingly ill-suited regulations and rate designs can be updated to keep pace. The global solar market has moved beyond its early, uncertain days. The luxury of behaving like start-ups […]

German utility RWE warned energy markets this week that low water levels on the Rhine River may affect the delivery of hard coal to some of its plants.

Watts Bar Unit 2 began commercial operation on October 19.

Software represents the largest revenue opportunity across all virtual power plant types, while energy storage dominates in the mixed asset segment, report finds October 05, 2016 05:15 AM Eastern Daylight Time BOULDER, Colo.–(BUSINESS WIRE)–A new report from Navigant Research examines the global market for virtual power plants (VPPs) and enabling technologies, providing an analysis of the market […]

As of October 5, the Paris Agreement—the first global agreement on efforts to limit and mitigate the effects of climate change—had been ratified by a sufficient number of countries, representing at least 55% of global greenhouse gas (GHG) emissions, to bring the agreement into force.

Lakeland Electric, the third-largest public power utility in Florida, reported that it saved $12 million in fiscal year 2015 through the use of a coal treatment at its McIntosh Power Plant Unit 3. The savings

The push for clean energy notwithstanding, no silver bullet can cure the challenges that our continued use of carbon engenders. Every form of energy production, green or black, clean or dirty, presents downsides. Siting an energy facility—whether clean energy, hydro, natural gas, coal or nuclear—inherently imposes some form of environmental harm. For renewables, one of […]

Owner/operator: Mátra Power Plant Co. Ltd. Hungary’s largest coal-fired power plant is a model of efficiency and environmental impact despite its 1960s-era vintage. Continual upgrades have kept the plant running smoothly, and a modern dense slurry ash-handling system keeps combustion residuals under control and allows for a zero liquid discharge posture. Unlike some of its […]

Owner/operator: NTPC Ltd. India’s state-owned generator NTPC operates a large fleet of power plants across the nation, and one of its top performers is found outside the capital of New Delhi. Staff at NTPC Dadri have taken a proactive, innovative approach to maintaining their plant, making it one of the most efficient in India despite […]

Owner/operator: Malakoff Corp. Bhd. Building a power plant on a site previously used for an aquaculture farm comes with more than a few challenges. For the Tanjung Bin Energy Power Plant, that meant some redesign and rework was required. Even so, the GE-led construction consortium made adjustments and delivered the state-of-the-art ultrasupercritical project on time […]

While it’s true that coal ash can be an environmental hazard if it’s not properly managed, there are a lot of positive uses for coal combustion products that actually provide benefits to the world. Many beneficial uses have been around for decades, but valuable new options are being developed, and some are starting to make […]

Like so many other power plant functions these days, regulatory and standards compliance can be automated. Know what you want an automated system to do before you make a vendor decision. As North American Electric Reliability Corp. (NERC) Critical Infrastructure Protection (CIP) enforcement deadlines and audit dates loom—notably, CIP-003-6 in April 2017, which addresses the […]

High-speed turbine rotor balancing was once rare because of the costs and logistical challenges involved in doing it during an outage. That’s begun to change as economic options emerge, and experience is showing that high-speed balancing can pay big dividends in reliability and maintenance costs. To a maintenance engineer or fleet manager, unwanted vibration in […]

South Africa’s state-owned utility faces recent generation shortages, plant construction problems, load shedding, and uncertainty at the African continent’s only nuclear power plant. And that’s just on the generation side. Moves on the business planning and regulatory side are painfully slow and could, some argue, be writing the utility’s obituary. Eskom, South Africa’s state-owned monopoly […]
