What’s on the agenda for the utility industry today and into the future? Platts and Capgemini asked the industry leadership in their latest survey. The answers revolve around regulation, finance, and human resources.

Now that many flue gas desulfurization (FGD) systems are reaching middle age, corrosion repairs of structural and process vessels are becoming more common. Corrosion is caused by condensates of acids formed during the FGD process, which accelerate pitting and crevice corrosion, particularly in scrubbers where high sulfate solutions are present. Scrubbers lined with 2205 duplex stainless steel are among the most vulnerable to pit or crevice corrosion, from both chlorides and fluorides.

It is fair to say that 2011 is bringing some uncertainty into the nuclear energy industry. The tsunami and subsequent events at Fukushima present Japan and our industry with new challenges but also serve as a catalyst for continuous improvement. In the U.S., we are learning from these events and improving our operations, designs, and emergency response approaches to make our plants safer, more efficient, and more environmentally friendly.

Uncertainty about China’s role in world trade and its current monopoly over critical rare earth minerals continues to roil supply chains in energy technology markets. Will the World Trade Organization bring China into the fold, or will China ignore the international forum that it lobbied hard to join several years ago?

When adding, modifying, or upgrading a system, many critical infrastructures conduct a factory acceptance test (FAT). A FAT includes a customized testing procedure for systems and is completed before the final installation at the critical facility. Because it is difficult to predict the correct operation of the safety instrumented system or consequences due to failures in some parts of the system, a FAT provides a valuable check of these safety issues. Similarly, because cyber security can also impact the safety of critical systems if a system is compromised, it makes sense to integrate cyber security with the FAT.

The process of handling employee complaints of workplace discrimination or harassment is filled with potentially disastrous pitfalls. Here are some things to avoid.

From the East Coast to the Lone Star State, a number of elected officials and power industry representatives are bashing the new aggressive regulation aimed at controlling specific power plant emissions. Complying with a federal court mandate, the U.S. Environmental Protection Agency (EPA) finalized the Cross-State Air Pollution Rule (CSAPR) on July 6. The new […]

In 2010, the 2,310-MW Adapazari Power Plant achieved 99.8% availability, which is nearly 7% higher than the industry average and a global record in F-class gas turbine technology. The new turbine upgrade is helping ENKA Power bolster Turkey’s evolving economy by improving its energy sector’s efficiency and productivity.

"Asset health" offers a conceptual path to integrating information technology with operations technology, thereby overcoming the common management problem of "siloed data," according to a recent study by The McDonnell Group.

Known for its progressive, pro-sustainability policies, the City of Tallahassee recently repowered a 30-year-old conventional steam plant unit, turning it into a new 300-MW facility. The utility redesigned the Arvah B. Hopkins Generating Station, Unit 2 as a 1 × 1 combined cycle plant in order to improve efficiency, switched the primary fuel from oil to natural gas, and thereby reduced fuel costs and emissions. The plant’s flexible design even will enable expansion to a 2 × 1 configuration when additional capacity is needed in the future.

The rise of shale gas in U.S. energy markets has profound economic implications. It has the potential to transform the existing market and bring opportunities for new markets. But shale gas also raises regulatory challenges and the likelihood of litigation. Here’s an introduction to the issue and a primer on the regulatory and legal ramifications of the shale revolution.

Managing construction of the 550-MW Astoria II Combined Cycle Plant in the midst of Queens, a densely packed New York City borough, required extensive off-site modular construction and a high level of logistical organization. Now the new Astoria II plant is operating successfully in conjunction with the Astoria Energy I plant as the largest natural gas–fired power plant in the Big Apple.

Last summer, an international group of scientists and policy analysts under the auspices of the London School of Economics launched an ambitious effort to reshape the debate over global warming policy in a document known as The Hartwell Paper. This July, a similar group followed up with a new report, titled "Climate Pragmatism: Innovation, Resilience and No Regrets,"  which puts the earlier work into a North American context.

The new 2,100-MW Phase 1 EMAL combined cycle power plant provides dedicated power with a high level of reliability to the Emirates Aluminum Smelter Complex, which is designed to be the world’s largest aluminum smelter upon completion. Located on the Persian Gulf, the gas-fired combined cycle plant uses seawater cooling towers to eliminate thermal stress on local marine life.

In training for a sport, the common wisdom is "no pain, no gain." The same is true when it comes to fostering creativity in the workplace. Force yourself and your organization out of the easy path, break out of the rut, and gain as a result.

I examined the magnitude of electricity subsidies for renewables compared with conventional generation technologies in my May 2011 editorial, based on data from a 2008 report prepared by the U.S. Energy Information Administration (EIA). An updated EIA report released in July determined that federal government subsidies have risen substantially during the past three years. In fact, overall renewable energy subsidies have almost tripled, increasing from $5.1 billion to $14.7 billion. In my opinion, we aren’t getting value for the money spent.

The Irsching 4 Combined Cycle Power Plant has set a new world record in power plant efficiency with its new SGT5-8000H gas turbine. With an output of more than 578 MW and efficiency of 60.75% (net) achieved at a world record test run in May 2011, the plant demonstrates that climate protection, low-cost power generation, and flexible operation using fossil fuels can be attained simultaneously through technical advances. Due to its high efficiency, the gas-fired plant uses significantly less fuel and produces lower carbon dioxide emissions than traditional combined cycle plants.

Heat waves, droughts, and other weather and climate phenomena; economic woes; aging or inadequate infrastructure; fuel shortages. These are some of the most obvious causes that have led to record peaks in power demand or sudden drops in available capacity. The results have been sometimes debilitating load-shedding, brownouts, and blackouts around the globe this summer (and, in some cases, for much longer). Here’s an overview of which countries are affected by which difficulties.
