Plant of the Year: AES Gener’s Angamos Power Plant Earns POWER's Highest Honor

AES Gener recently completed construction of twin coal-fired, 260-MW units in the electricity-starved desert of northern Chile that may serve as models for future hybrid-fossil plant designs. For meeting an aggressive construction schedule, integrating a 20-MW battery energy storage system, embracing desalination, using the first-of-its-kind seawater cooling tower in South America, and employing innovative financing methods, the AES Gener Angamos plant has earned POWER’s 2012 Plant of the Year Award.

2011 Nuclear Industry Scorecard

The world nuclear industry experienced few substantial changes in performance metrics for 2011—beyond Japan, that is. In the aftermath of Fukushima, the once–world leading Japanese nuclear industry fell to the bottom of the rankings, perhaps for good.

Flow Control Chutes Reduce Fugitive Coal Dust

Moving thousands of tons of coal per hour at high speeds through a complex handling system is a main cause of airborne coal dust in a coal-fired plant. Depending upon the coal’s characteristics, that dust can become explosive when its concentration reaches 80 g/m3 and, hence, a threat to life and property. The best option is to stop the dust from becoming airborne in the first place.

Marmaduke Award: Combined Solar Technologies’ Hybrid Plant: Using Wastewater and Olive Pits to Produce Clean Water and Clean Energy

Combined Solar Technologies (CST) has designed, built, owns, and operates a water purification system located at the Musco Family Olive Co. facility in Tracy, Calif., that burns olive pits to purify highly saline wastewater through a distillation process while also producing electric power. For its pioneering approach, CST is the winner of POWER’s 2012 Marmaduke Award for excellence in plant problem-solving. The award is named for Marmaduke Surfaceblow, the fictional marine engineer and plant troubleshooter par excellence, whose exploits were chronicled in POWER beginning in 1948.

Marmy’s One-Squirt Celebration

Steve Elonka began chronicling the exploits of Marmaduke Surfaceblow—a six-foot-four marine engineer with a steel brush mustache and a foghorn voice—in POWER in 1948, when Marmy raised the wooden mast of the SS Asia Sun with the help of two cobras and a case of Sandpaper Gin. Marmy’s simple solutions to seemingly intractable plant problems remain timeless. This Classic Marmaduke story, published more than 50 years ago, reminds us that an overhaul or startup may not go as planned, but it can still have a happy ending.

New Environmental Rules Keep Pressure on Coal-Fired Generation

New U.S. Environmental Protection Agency regulations affecting the nation’s coal power plants are routinely in the national news. The latest proposed rule focuses on the release of carbon dioxide into the atmosphere. With a substantial amount of coal generation expected to be shut down (up to 40 GW to 50 GW in the coming years by some accounts), the new regulations are increasing the likelihood that this lost capacity will not be replaced by new coal generation.

Small Is the New Big: The B&W Small Modular Reactor

Small reactors are big news, particularly the 180-MWe Generation III++ Babcock & Wilcox mPower small modular reactor (SMR). This SMR has all the features of its larger cousins, but the entire reactor and nuclear steam supply system are incorporated into one reactor vessel, all about the size of single full-size pressurized water reactor steam generator. Expect the first mPower—and probably the first SMR—to enter service before 2022.

Smart Grid Award: Customers Motivate San Diego Gas & Electric’s All-Inclusive Smart Grid Vision

“If you build it, they will come” has proven a risky strategy for some smart grid projects. One of California’s largest investor-owned utilities faced the opposite challenge—customers whose behaviors necessitated a smarter grid. Customer involvement in and support for smart grid plans is a major reason SDG&E’s smart grid efforts continue to garner accolades, including the 2012 POWER Smart Grid Award.

Too Dumb to Meter, Part 3

As the book title Too Dumb to Meter: Follies, Fiascoes, Dead Ends, and Duds on the U.S. Road to Atomic Energy implies, nuclear power has traveled a rough road. In this POWER exclusive, we present the third chapter, “Micro-Mismanagement by Committee.” During the frenzy to manage atomic power after World War II, Congress created an executive branch agency that threatened to be too independent, too powerful, and too isolated from the rest of government. Compounding their errors, perhaps in recognition of what they had created, the solons also developed a way to insert their own power into the action. This proved to be a major mistake—blurring the lines between executive and legislative authority—causing no end of problems for the nation’s nascent atomic energy venture.

Wind Energy Blown Away by Natural Gas

The environmental push for renewables and mandates to force them into existence are rightly facing some serious headwinds. The American Renewable Energy Production Tax Credit Extension Act of 2011 foundered in Congress, and more states are experiencing significant power rate increases to cover renewable energy production costs. While renewables are generally not ready for prime time in large quantity on today’s power grid, that doesn’t mean environment concerns ought to be trashed, especially when a more effective off-the-shelf solution is available.

Legal & Regulatory

Proposed Cooling Water Rule’s Ripple Effects

The U.S. Environmental Protection Agency (EPA) has a long history of making waves with the electric power industry because of its efforts to regulate the way thermal power plants construct and operate their cooling water intake structures (CWIS). These structures divert billions of gallons of water into power plants’ cooling systems and can injure or kill billions of aquatic organisms.

Breaking the Cycle of Reactive Maintenance

Nobody can schedule unplanned events that will affect power generation. And no one wants to start a day expecting an emergency to occur. But when critical systems fail in the power supply system, it’s time to respond. That’s a given of power plant maintenance.

Tubular Turbine Hydropower Plant Comes Online

Albania this June inaugurated its first major hydropower project since the early 1980s, bringing online Ashta I, the first of two run-of-river plants with a combined capacity of 53 MW. At the inauguration ceremony, Albania’s Prime Minister Sali Berisha called the plant “a novelty” because it is the largest in the world to use advanced tubular turbines technology.

Speaking of Power

Tactical Advantage

A three-judge panel of the U.S. Court of Appeals for the D.C. Circuit on June 26 unanimously rejected all pending legal challenges against the U.S. Environmental Protection Agency’s (EPA’s) interpretation of the Clean Air Act (CAA) that allows the agency to regulate greenhouse gases (GHGs). What is the EPA’s future strategy in its war on coal?
