Since 2010, the year Stuxnet was discovered, there has been an increase in industrial control system (ICS) vulnerability research and reported vulnerabilities, exploits, and ICS-specific malware (Figure 1)

How do women in the power generation business—in power plants and in the vendor community—view their jobs in this male-dominated industry? In what is likely the first survey open to women across the industry, they told us. The November 2008 issue of POWER included an industry-first in-depth look at women in the power industry, “Workforce […]

Construction was suspended on Watts Bar Nuclear Plant Unit 2 in the late 1980s, and the plant sat idle for more than 20 years. Now, through equipment refurbishment and replacement, Unit 2 is on track to become the first new commercial nuclear reactor to come online in the U.S. in the 21st century.  Electricity consumption […]

Boiler slagging and fouling, and the resulting frequent operation of sootblowers, are some of the major operations and maintenance factors that can negatively affect power plant reliability and efficiency. Boiler slagging and fouling are among the most common causes of maintenance headaches at coal-fired power plants. Though you cannot totally eliminate the problem, following proper […]

NRC Advances Design Certification of Westinghouse SMR, South Korea’s APR1400. The Nuclear Regulatory Commission (NRC) on Feb. 27 approved Westinghouse Electric Co.’s testing approach for its small modular reactor (SMR) design—a “significant” step that the Toshiba Corp. company said will reduce the time ultimately needed to obtain design certification. By granting a safety evaluation report […]

Sometimes overlooked and underappreciated, a power plant condenser can make or break your efficiency and power delivery goals. Understanding how important a role your condenser plays is a good step toward greater heat rate awareness. As part of a university class on power generation systems that I teach, I show my students a Sankey diagram […]

The Egypt Economic Development Conference (EEDC) in Sharm El-Sheikh resulted in some big agreements for the Egyptian government, including a reported $10.5 billion deal with Siemens and a $1.7 billion order with GE. The conference was held March 13–15, 2015, and was touted as a key milestone of the government’s medium-term economic development plan, which […]

Advocates for the continued reliance on coal for baseload electricity cheered late last year when North America’s largest power-related carbon capture and sequestration (CCS) facility was commissioned. Since then, that pool of advocates is evaporating as prominent electricity industry decision-makers publicly distance themselves from coal and champion alternatives for a low- or no-carbon future. If […]

In the UK, which has the world’s largest offshore wind capacity, in large part due to government backing, formal negotiations have begun on public funding of a £1 billion ($1.48 billion) tidal lagoon project to produce electricity from turbines in Swansea Bay, South Wales. The 320-MW project (Figure 3)—which could be the first of its […]

How to give electricity customers who can’t take advantage of rooftop solar access to the sun? Community solar—a shared resource—is a fast-growing segment of the renewable energy market, making solar photovoltaic power more accessible while offering another approach to distributed generation. Mention “solar energy” and the image that probably comes to mind is an array […]

General Electric’s (GE’s) new flagship HA turbines, which will be the largest and most efficient in their class when deployed, will see their first delivery at EDF’s Bouchain combined cycle plant in France this summer. The first U.S. order is from Exelon for four 7HA turbines intended for expansions at the Wolf Hollow and Colorado […]

Coal has dominated fuel choices in Asia since 2010, even in gas-centric Southeast Asian countries, and many forecasts assume that coal will remain the region’s most economical option. But lower natural gas prices and individual market conditions are putting a dent in coal’s future in the region, some experts note. According to Graham Tyler, Wood […]

The life of a wind turbine can be pretty precarious. The blades—made of laminated materials, such as composites, balsa wood, carbon fiber, and fiberglass—can reach speeds up to 180 miles per hour at the tip, which means even small particles in the air can cause damage to the surfaces. It’s probably no surprise that lightning […]

If you have been paying attention to renewable energy growth in the U.S. during the past decade, you likely know that Texas leads the nation in wind power development. In fact, the portion of the state that is served by the Electric Reliability Council of Texas (ERCOT)—about 75% of land area and about 90% of […]

This summer, the Environmental Protection Agency (EPA) will finalize its Clean Power Plan under Section 111(d) of the Clean Air Act, requiring existing fossil fuel–fired electric generating units (EGUs) to cut carbon dioxide emissions to 30% below 2005 levels by 2030. The rule will require states to meet specific reduction goals and also allow states […]

Falling prices and technological improvements have brought battery storage systems into direct competition with traditional distributed generation, demand response, and peaking generation resources. But making one work efficiently and profitably is not just plug and play.   Last fall, Southern California Edison (SCE) had some big decisions to make. The giant utility, which serves 14 […]

Renewable generation may be the most talked-about form of distributed power these days. However, historically, engine- and turbine-based smaller-scale generation—strategically located where needed by loads or for grid support—has supplied valuable distributed power. For many reasons, the roles for distributed power provided by rotating and reciprocating equipment continue to increase. The U.S. utility industry is […]

As I write this column at the beginning of spring, I have two kinds of spring fever: excitement about warming temperatures that bring spring flowers and the “hay fever” caused by tree pollens. I have mixed feelings about spring. I mention this only because the power industry is experiencing a spring fever of its own. […]

The digital economy has changed the way we shop for clothing, travel, communicate with friends and family, consume news, and watch television—among so many other things. But the innovative potential of the digital economy has not yet found a place within the electric system. With that important goal in mind, New York has embarked on […]
