Legal & RegulatoryHybrid generation markets endanger competition and innovation
Competition in power generation fosters technical innovation, cleaner power plants, and downward pressure on prices. Before the 1980s, such competition was almost nonexistent: vertically integrated utilities built and operated the vast majority of U.S. plants with oversight by state regulators. The Public Utility Regulatory Policies Act of 1978 and the Energy Policy Act of 1992 […]

GasDesigning HRSGs for cycling
With U.S. combined-cycle plants increasingly being cycled—rather than being run continuously, as they were designed to do—owner/operators worry that units expected to last two or three decades may survive only a few years without an expensive overhaul. Cycling takes as much of a toll on heat-recovery steam generators as it does on gas turbines. Whether you’re procuring a new HRSG or adapting an existing one for cycling service, robust design features should be what you’re looking for.

CoalStressed merchant industry hopes for better days
The U.S. power generation industry is changing at warp speed, via regulatory changes, consolidation, mergers, and sales of assets at yard-sale prices. New players have entered the market and become major players overnight, while several mainstays have gone bankrupt. Though many of the latter blamed high gas prices for their woes, well-diversified merchants enjoyed a record year. Whatever changes are in store for the business of combined-cycle generation, you can be sure that innovations in plant design and O&M such as those described in this special section will keep pace with them.
