The articles in this special section discuss several case studies of fuel supply risks and how these risks to reliability and electric energy costs are being addressed. Risks have been quantified through studies that identify fuel supply limitations and the lessons learned from operating experience. Greater fuel certainty is being achieved through better coordination of electric system needs with fuel supplies, improvements to the natural gas and electric power system infrastructures, and new market incentives that reward the secure operating performance of resources. © 2014 IEEE.
