As California begins to turn the page on the first chapter of its efforts to combat climate change through AB 32 and to prepare for greater emissions reductions over the coming decades, the California Energy Commission (CEC) and California Public Utilities Commission (CPUC) are considering what these changes will mean for electricity transmission infrastructure. To that end, CEC Chair Robert Weisenmiller and CPUC President Michael Picker sent a letter to Cal-ISO President and CEO Stephen Berberich on July 31, 2015 asking him to participate in the planning stages of the Renewable Energy Transmission Initiative (RETI) 2.0. Since 2008, the first iteration of RETI has served as a statewide initiative to identify and implement the energy transmission projects needed to accommodate California’s renewable energy requirements.

Now, with Governor Brown’s executive order to cut California’s greenhouse gas emissions by 2030 and a number of legislative proposals advancing to set further greenhouse gas emissions reductions targets for 2030 and beyond, as well as the US EPA’s federal Clean Power Plan encouraging regional coordination among states to increase renewable electricity production, the CEC and CPUC feel that the time has come to bring RETI up to date.
