Modeling Assumptions for the 2020-2021 Transmission Planning Process

Resource-to-busbar mapping ("busbar mapping") is the process of refining the geographically coarse electricity resource portfolios produced in the California Public Utilities Commission's (CPUC) Integrated Resource Plan (IRP) proceeding, into plausible network modeling locations for transmission analysis in the California Independent System Operator's (CAISO) annual Transmission Planning Process (TPP).

The following documents provide busbar mapping results along with other assumptions required for TPP modeling, and associated supporting documentation.

A Modeling Advisory Group webinar was held on May 22, 2020 explaining this material. Please refer to the 2019-2020 IRP Events and Materials webpage for access to the presentation slides and webinar recording.
