 Welcome to the TSIN Registration web site, the first step to conducting business on OASIS Phase 1A and completing NERC interchange transaction tags.  All data registered using this new process became effective March 1, 1999, coincident to the implementation of OASIS Phase 1A.

This TSIN Registration process integrates three processes:

  1. OASIS registration,
  2. NERC's Interchange Transaction Tagging registration, and
  3. Registration of transmission product attribute values and Points of Delivery/Points of Receipt (POD/POR)

ATTENTION TSIN USERS – THE TSIN SYSTEM WILL BE RETIRED AND REPLACED WITH THE NAESB ELECTRIC INDUSTRY REGISTRY.  REGISTRATION FOR THE NEW REGISTRY BEGINS MID-MARCH.  FOR MORE INFORMATION, PLEASE VISIT:  http://www.naesb.org/WEQ/weq_eir.asp.
