The California ISO relinquishing Operational Control of Oak Park and Chico Transmission Lines

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 three lines below:

1. Chico "A"-Dayton Road - from Chico "A" to 1/17
2. Contra Costa-Shell Chemical #1
3. Oak Park Tap - from A3/86 to Oak Park

The ISO, in consultation with PG&E, has determined that it no longer requires operational control over these three 60kV transmission lines to fulfill its Balancing Authority Area responsibilities. This determination was made because the facilities are being retired from networked transmission service (reference Section 4.7.1(iii) of the TCA).

Interested parties have 45 days (no later than April 5, 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 ISO will then respond to any objections and post the response on the ISO website as provided in Section 4.7.2 of the TCA.
