The Demand Response Review is a survey of the Demand Response (DR) programs and initiatives in each of the six Commission-approved RTOs/ISOs: California ISO; Midwest ISO; ISO New England; New York ISO; PJM; and Southwest Power Pool. The entry for each RTO/ISO is divided into three sections. The first section provides a synopsis of the ISO's existing DR programs, if any. The second covers ongoing DR initiatives and future programs. Finally, the third section outlines issues in connection with DR in the region typically includes a discussion of potential barriers to DR participation and recommendations to FERC and/or state regulators, among other issues.
