The Transmission Reliability Program was established by Congress in 1999 to support a national laboratory/electricity industry partnership to conduct research on the reliability of the nation’s electricity delivery infrastructure during the transition from regulated markets to competitive markets under restructuring. Competition and market forces are creating an exponential increase in the volume of power transactions and causing the grid to be used in ways for which it was not designed. The Transmission Reliability Program is developing advanced technologies, including information technologies, software programs, and reliability/analysis tools to support grid reliability and effi cient markets during this critical transition.
