The California ISO is relinquishing operational control of certain PG&E transmission facilities

According to Section 4.7 of the Transmission Control Agreement (TCA), as requested by Pacific Gas and Electric Company (PG&E), the California ISO provides notice that it intends to relinquish operational control over the two lines below:

1. Howland Road Substation to Tesla Motors 115kV
2. Monte Rio to Fulton 60kV 

The California ISO, in consultation with PG&E, has determined that it no longer requires operational control over these two transmission lines to fulfill its Balancing Authority Area responsibilities. This determination was made because the facilities have been modified due to new construction activities and are now classified as local distribution facilities and subject to exclusion from the CAISO Operational Control (reference Section 4.7.1(ii) of the TCA).  

Interested parties have 45 days (no later than July 20, 2026) within which to submit written objections to the proposed removal to Riddhi Ray at rray@caiso.com with a cc to RegulatoryContracts@caiso.com. The California ISO will then respond to any objections and post the response on the California ISO website as provided in Section 4.7.2 of the TCA.  

Please contact Riddhi Ray at rray@caiso.com with a cc to RegulatoryContracts@caiso.com with any questions.
