The Commission denies rehearing and otherwise reaffirms its determinations in Order No. 743. In addition, the Commission clarifies certain provisions of the Final Rule. Order No. 743 directed the Electric Reliability Organization (ERO) to revise the definition of the term "bulk electric system" through the ERO's Reliability Standards Development Process to address the Commission's policy and technical concerns and ensure that the definition encompasses all facilities necessary for operating an interconnected electric transmission network pursuant to section 215 of the Federal Power Act.
