The President may, by order, stay the application of any provision of this chapter, or any rule or order thereunder, applicable to any new or existing electric powerplant, if the President finds, and publishes such finding, that an emergency exists, due to national, regional, or systemwide shortages of coal or other alternate fuels, or disruption of transportation facilities, which emergency is likely to affect reliability of service of any such electric powerplant.
