Having Transmission Customer status allows your company to do business with SPP on the Open Access Same-Time Information System* (OASIS). No annual fee is required to become a SPP Transmission Customer.

Customer Registration Time Line

Registration to become a SPP Transmission Customer is a 45-day process. Transmission Customers become active in SPP models on the first day of February, April, June, August, October, or December. For example: A company requesting the production date of April 1 should have all completed documents submitted on or before February 15.

* Open Access Same-Time Information System (OASIS)

OASIS is an electronic posting system that the Transmission Service Provider maintains for transmission access data and that allows all transmission customers to view the data simultaneously.

** Local Security Administrator (LSA)

LSA is the primary person at an entity who sets up user access to Integrated Marketplace applications, and they are able to:

  • Add, edit, and delete users
  • Assign and remove roles from users
  • Add, change, and remove user access from the MCST application
  • Vet and approve users requesting RMS access

Note: All transmission service settlement invoices, statements, and additional information have remained in the SPP EIS Portal. A digital certificate will be needed for the LSA. This certificate can be the same certificate used for the Integrated Marketplace.
