2009 Industry Forecast: Existing Generating Assets Squeezed as New Project Starts Slow
Most forecasting reports concentrate on political or regulatory events to predict future industry trends. Frequently overlooked are the more empirical performance trends of the principal power generation technologies. Solomon & Associates queried its many power plant performance databases and crunched some numbers for us to identify those trends.
2009 Industry Forecast: New Power Politics Will Determine Generation’s Path
The U.S. power industry’s story in 2009 will be all about change, to borrow a now-familiar theme. Though the new administration’s policy specifics hadn’t been revealed as POWER
editors prepared this report, it appears that flat load growth in 2009 will give the new administration a unique opportunity to formulate new energy policy without risking that the lights will go out.
A Fresh Look at Coal-Derived Liquid Fuels
Thirty-five percent of the world’s energy comes from oil, and 96% of that oil is used for transportation. The current number of vehicles globally is estimated to be 700 million; that number is expected to double overall by 2030, and to triple in developing countries. Now consider that the U.S. has 27% of the world’s supply of coal yet only 2% of the oil. Coal-to-liquids technologies could bridge the gap between U.S. fuel supply and demand.
Patchy Progress in Europe with Radioactive Waste Management
The future of high-level nuclear waste disposal at Yucca Mountain remains uncertain as a new U.S. administration considers its nuclear agenda. The European Union’s policies remain just as unsettled. With new projects under construction in several countries and a nuclear ban in effect in others, no unified long-term storage approach is in sight.
Upgraded Control System Adds to Merchant Plant’s Bottom Line
If the rotating equipment and boiler are a plant’s brawn, then a control system that efficiently integrates myriad plant functions is its brains. Luckily, in a power plant, we can perform a brain transplant when the control system becomes unreliable or too costly to maintain. But first, you have to justify that surgery.

Is a Green Future Realistic with an Economy in the Red?
California Governor Arnold Schwarzenegger recently signed an executive order expanding the state’s renewables portfolio standard (RPS) requirement to 33% by 2020. The executive order formalizes what has been generally assumed for some time: A 33% RPS requirement will be needed for California to achieve its ambitious greenhouse gas (GHG) emissions reduction goals.

Conserve Water by Improving Cooling Tower Efficiency
Though an abundant supply of freshwater has been taken for granted in many parts of the world, its availability is becoming less certain, even in North America. Water is a valuable resource and commodity that needs to be efficiently managed to minimize waste, reduce energy consumption, and control cost, especially for power generation. The industry must respond by seeking out more efficient ways to use water, such as by implementing water recycling and reuse strategies, especially for critical equipment like cooling towers.
Improving Workforce Connectivity
Wright-Hennepin Cooperative Electric Association (WHCEA) is an electric distribution utility located in Rockford, Minn., that has been serving Wright County and western Hennepin County near Minneapolis with electricity since 1937. WHCEA is a not-for-profit, member-owned energy and service cooperative dedicated to enhancing the quality of life of its members and providing reliable services. Its field operations department consists of 35 fleet members who focus on building and maintaining electric power lines.
Stopping Natural Gas Leaks
Chances are you have endured the tedious process of removing fuel piping when maintaining just about any gas turbine, especially aero-derivative engines that are usually swapped out rather than repaired in place. One of the most time-consuming jobs after reassembling the fuel piping is checking for leaks at all the flanges. In a large frame-size turbine, that means sealing up to 64 flanges and then removing the seals after the leak testing.
Training the Next Generation of Welders
Concern about the shortage of skilled workers for the energy industry has grown considerably over the past few years. Most discussions have focused on the shortage of engineers, but recently concerns about the scarcity of technical crafts have arisen as well.
This spring, Xcel Energy, along with state and technology partners, is set to test what the utility says is the first battery capable of storing wind energy. The ability to store energy from renewable generation sources with variable output is key to maximizing the value of renewable power in general and to Xcelâ€™s "smart grid" plans in particular.
Brazil Approves Hotly Contested Construction of Amazon Dam
In an effort to more than double its power capacity by 2030, the Brazilian government in November approved construction of a controversial $3.9 billion hydroelectric dam on the Madeira River, in the Amazon. When completed in 2013, the Jirau hydroelectric plant could add 3,300 MW to the country’s already massive 59 GW hydroelectric capacity.
CO2 Source and Sink Tracking Improving
Many opponents of climate change policies and regulations argue that it is unfair to penalize some sectors — like power generation — more heavily than others when it’s difficult to prove precisely where specific greenhouse gas (GHG) emissions are coming from, where they’re going, and what effect they are having. Toward the ends of scientific understanding and sound public policy, scientists are making progress in isolating GHG sources and sinks.
Invasive Species and Water Intakes
On October 21, a mass of basketball-sized jellyfish managed to accomplish what activists of every stripe had failed to do: Abruptly shut down Pacific Gas & Electric Corp.’s (PG&E) 1,118-MW Diablo Canyon Unit 2 reactor in San Luis Obispo County, Calif. (Figure 8).

The Race to Commercialize Mini–Nuclear Reactors
Though the resurgence of interest in nuclear power in recent years has spurred development of an assortment of reactor designs, emphasis has mostly been on those with capacities to produce thousands of megawatt-hours of baseload power, as is the case with designs from General Electric, AREVA, Westinghouse, and Mitsubishi that are under active review by the U.S. Nuclear Regulatory Commission (NRC). Power projects using any of those designs will be developed at the cost of many billions of investment dollars.
Speaking of Power
New Year’s Resolutions
Why is it that so many of our New Year’s resolutions are focused on self-enrichment, yet they are the first promises we break? The typical resolutions — "get more exercise" or "stop smoking" — are recycled yearly. Surveys find that most resolutions are abandoned or forgotten by, appropriately, Ground Hog Day. I believe it’s time to reboot our resolution-setting software and refocus on others instead of ourselves.
