Current Status, Plans, and Constraints Related to Expansion of Natural Gas-Fired Power Plants, Pipelines and Bulk Electric Transmission in the California/Mexico Border Region

摘要

The report describes the current status and expansion plans for gas-fired power plants, bulk electric transmission, and natural gas transmission pipelines in the California/Mexico border region. Existing and forecasted supply-demand balance for both electric and gas capacity are described for specified zones on both sides of the border, along with flow constraints between the zones. Natural gas flow constraints and pipeline projects discussed in the report include the path between Erhenberg/Blythe and Baja California, pipeline capacity across northern Baja California, the delivery constraint south of Moreno in the Southern California Gas system, and pipeline capacity between San Diego Gas & Electric (SDG&E) and Baja at Otay Mesa. Impacts of Sempra Energys Costa Azul LNG terminal project on pipeline constraints is also described. A description of electric transmission constraints and proposed projects is provided including Western Electricity Coordinating Council (WECC) Path 45 between Baja California and the California Independent System Operator (California ISO). Also included is the existing and proposed electric transmission capacity from the Imperial Valley to the west and north, and the impact of the proposed Sunrise Powerlink and Green Path North transmission projects.
