A Primer on Optimizing Fleet Operations
The power industry needs a straightforward definition of "fleet optimization" and a game plan to achieve the promised economic gains of optimizing. This need has become more urgent because integrating nondispatchable renewable resources requires more complex optimization strategies. The bottom-up approach presented here applies well-understood optimization principles and techniques that will help power producers minimize their fleetwide cost of production, independent of the technologies used to generate electricity.

Enhanced Condenser Tube Designs Improve Plant Performance
Enhanced condenser tube designs can significantly improve the heat rate and performance of fossil and nuclear plants. Using the optimum number of tubes and replacement tube sheets will cost more than simply replacing plain tubes. However, the investment’s simple payback is measured in only weeks, which builds a strong case for using an enhanced tube design as part of your next condenser overhaul.

Rethinking the Power Industry’s Dash to Gas
During a recent meeting of state utility commissioners, the CEO of a Fortune 500 electric power company said natural gas prices promise reliability but "always break your heart." What breaks my heart is the electric power industry’s ongoing love affair with natural gas. Using natural gas for generating electricity is not the best or highest use for this clean, green, and domestically abundant resource.

U.S. Spins Nuclear Wheels as Other Nations Roll Out New Plants
President Barack Obama’s January State of the Union speech called for incentives to make clean energy profitable — mainly through the construction of a new generation of nuclear power plants. That comment, an apparent effort to reach out to Republican members of Congress, drew furious applause. Within three weeks, the president’s backing of nuclear power had already made a significant impact on the U.S. nuclear sector.

Real-Time Control of Coal Quality Improves Reliability
Poor lignite fuel quality had plagued the Red Hills Power Plant since it began operation eight years ago. The solution: real-time measurement of coal properties that has allowed Red Hills Mine to carefully monitor fuel quality and adjust fuel collection processes to ensure that only high-quality fuel is delivered to the plant. Now all delivered fuel is consumed, and plant reliability is much improved. It’s a classic win-win project.

Strategies to Reduce Sulfuric Acid Usage in Evaporative Cooling Water Systems
Concentrated sulfuric acid is often used to prevent calcium-based scale formation on condenser and heat exchanger tube surfaces in power plant evaporative cooling water systems. Unfortunately, the chemical’s price has jumped more than 300% over the past three years. If the rising cost of water treatment has you under the budget gun, here are some alternative strategies that can reduce or even eliminate your sulfuric acid usage.

Determining Carbon Capture and Sequestration’s Water Demands
The U.S. Department of Energy’s National Energy Technology Laboratory is pursuing a new integrated energy-water R&D program that addresses water management issues relative to coal-fired power generation that takes into account the major impacts of CCS on water use. The goal of this research is to promote more efficient use of water in power plant operations and increase the availability of heretofore unusable waters for power plant use. Those practices can mitigate the impacts of CCS on power plant water use and allow for continued development of energy resources.

Harnessing Energy from Upward Heat Convection
The atmospheric vortex engine exploits the natural energy content of the vortex produced during upward heat convection in the atmosphere. The heat source can be solar energy, warm sea water, warm humid air, or even waste heat rejected in a cooling tower. When mature, the technology — currently in the small-scale testing phase — promises to be an efficiency game-changer for fossil-fired power plants.
