Revised transmission planning process

To help achieve the state's 33% Renewables Portfolio Standards (RPS) target, the California ISO proposes to add a new category of transmission projects that will facilitate the necessary expansion of the electric grid to support renewable resource policy objectives, as well as a transmission project evaluation process that will use commercial interest tests and other criteria to determine whether projects are eligible to receive conditional or final approval by the ISO.

Business practice manual effective: August 2, 2011
