Cheaper, faster options already exist
California's grid operator (CAISO) has found that reconductoring existing lines with advanced conductors can roughly double their capacity within the same right-of-way — among the most cost-effective options available, and in CAISO's own words “quicker (and often less politically embattled) than greenfield transmission.” [1]
Grid-enhancing technologies and rebuilds on existing corridors can add capacity without carving a new path through Temecula Creek. The environmental review must seriously study a reasonable range of alternatives — including these and the “no project” option.
Question the “need”
The line was justified in CAISO's 2022–2023 plan as policy-driven — to move renewable power — not to serve local load, and no specific local-demand driver has been stated for it. That makes the case for an updated, independent look at whether a new corridor is warranted at all. [2]
