Regional Tariff Working Group
Regional Tariff Working Group
The Regional Tariff Working Group (RTWG) develops, implements and oversees SPP’s Open Access Transmission Tariff. The RTWG provides input on regulatory or implementation issues not specifically covered by the tariff and issues where there may be conflicting or differing interpretations of the tariff.
The RTWG is comprised of representatives from transmission-owning members with up to an equal number of representatives of transmission-using members from the SPP membership. The RTWG scope in the governing documents folder provides more information about this group and its work.
