Our response to COVID-19
We’ve made some changes due to COVID-19, including suspending service disconnections for residential and small business customers for nonpayment, and only continuing critical work needed to protect public safety and reduce the risk of wildfires. Learn more here. If you have recently lost your job, even if you are receiving unemployment benefits, you may qualify for a reduced energy rate through our CARE or FERA programs.

Interconnecting under SCE’s TOT

SCE’s Transmission Owner Tariff (TO Tariff, or TOT) describes the terms under which SCE provides open access to its transmission system to wholesale customers seeking to:

  • Interconnect generation facilities to SCE’s transmission system to deliver energy and capacity services to the California Independent System Operator (CAISO) controlled grid,
  • Interconnect wholesale load to SCE’s transmission system, or
  • Interconnect new transmission facilities to SCE’s transmission system.

SCE’s TOT also sets revenue requirements and applicable rates and charges for transmission access over the CAISO controlled grid and set the terms and conditions for transmission expansion.

SCE’s TOT is not applicable for customers seeking service under SCE’s retail rates, or interconnection of power projects to SCE’s distribution system, or for any other purpose not authorized by the Federal Energy Regulatory Commission (FERC).

The information on this page serves as a reference for SCE’s TOT. In case of discrepancies between the content of this page and SCE’s TOT, the currently approved TOT will govern. Note that the TOT currently posted at SCE.com may not reflect updates to the tariff that may be pending before the FERC.

DISCLAIMER: The guidelines in this section are provided with the intent to help SCE’s customers understand SCE’s Interconnection Procedures. However, in the case of discrepancies with SCE’s rules, such tariffs and regulations will prevail.
