ABSTRACT: Switching from coal- red to natural gas- red generation and increasing the thermal efficiency (energy gen-erated per unit of energy burned) of fossil fuel red electricity generation plants has been identi fied as ways of achieving meaningful emission reductions. In this study, we examine the fuel-price responsiveness across gas plant technologies and across the market structures in which the plants operate. We find that there are signi ficant diff erences in the generation and efficiency responses of gas plants to fuel prices across generation technologies and market structures. Specifi cally, our results indicate that, regardless of market structure, generation from natural gas combined cycle (NGCC) plants is responsive to both coal and gas prices, but that generation from simple cycle (NGSC) plants only respond to gas prices. On the other hand, with respect to efficency, we generally nd that only NGCC plants operating in deregulated regions show statistically signifi cant efficency improvements in response to coal price increases and that, generally, neither NGCC or NGSC plants, regardless of market structure, respond in any signi ficant way to gas prices. Finally, using these parameter estimates, we calculate emissions savings from efficency improvements and fuel-switching possibilities.
