Imperial Valley–Termoeléctrica de Mexicali intertie

CAISO ↔ Baja California · AC transmission

A separate double-circuit 230 kV AC generator tie from the Imperial Valley substation to Sempra's Termoeléctrica de Mexicali plant. It was constructed under Presidential Permit PP-235 and is owned by Termoeléctrica U.S. DOE's 2024 filing describes the plant as electrically connected through this line; Sempra reports the plant operating in 2025. The marker converts the border UTM coordinate in the DOE filing; its datum is unspecified, so treat the position as approximate. No dedicated live flow is matched to this facility.

Sources and method

No operator flow feed is linked to this profile. The map and hardware describe the registered connection, not a current power transfer. A rating describes the equipment; an operator’s posted directional limit, when available, is a separate operating value. The map point identifies a sourced terminal or crossing where available, or a representative connection point; it does not trace the full route.
