Renewables Transmission Planning and Development

Transmission is to renewable energy resources what the transcontinental railroad was to opening up the West. We need to connect California’s renewable resource-rich regions—wind from Tehachapi, geothermal and wind from the Imperial Valley, concentrated solar power from the Mojave Desert, and to a lesser extent, bio-energy from the Central Valley—to the large coastal urban load centers of the state where it is needed. Making this vital connection will require a series of massive, multi-billion dollar investments in new transmission infrastructure. In conjunction with the California Energy Commission, we have been promoting a unique stakeholder collaboration project to expedite planning and development of vital transmission projects.

Recent Developments:

CEERT’s comments in the Integrated Resource Planning proceeding emphasized the importance of generation portfolios being submitted to the CAISO transmission planning process (TPP) based on the statutory requirements of SB 100, in order to ensure that transmission gets built for sufficient renewable resources to meet the state’s energy and climate goals. We have continued to explore the need for policies and administrative action to ensure that the TPP, and the future generation scenarios it relies upon from the CPUC and the CEC, include transmission expansions needed to meet 2030, 2040 and 2050 climate and clean energy targets.
