Zero-Emission Vehicles Proceedings

The CPUC facilitates the deployment of Zero-Emission Vehicles (ZEV) and their supporting infrastructure to develop and commercialize the transportation technologies that are essential to achieve California’s renewable energy, air quality, and climate change goals.

Overview of CPUC Policymaking

Pursuant to Executive Order (B-16-2012, B-30-15) and the Climate Change Scoping Plan, the CPUC, jointly with other State Agencies, is responsible for reducing transportation greenhouse gas emissions (GHG) 80% below 1990 levels by 2050. CPUC develops policies in four broad categories, consistent with milestones set forth in the Order and Plan:

  • Coordinating the buildout of infrastructure to charge 1 million ZEV by 2020;
  • Encouraging vehicle adoption such that 1.5 million ZEVs are driven on roads by 2025;
  • Designing rates and incentives for low carbon fuels to halve petroleum use by 2030; and
  • Utilizing Vehicle-Grid Integration technologies to use transportation energy as a resource that facilitates a 50% renewable electricity system by 2030.

CPUC’s work in transportation energy began in 1990 by implementing policies that developed equipment and infrastructure to facilitate the use of electricity and natural gas to fuel Low-Emission Vehicles (P.U. Code 740.3) to reduce criteria air pollutants. In 2006, the State adopted Assembly Bill (AB) 32, the Global Warming Solutions Act, which aims to reduce greenhouse gas emissions to 1990 levels by 2020. In 2008, the Air Resources Board (ARB) created an initial Climate Change Scoping Plan, which identified that efficient, zero-emission vehicles using low carbon fuels are “needed as vital components” for the State to achieve its GHG emission reduction goals. In 2009, pursuant to the Scoping Plan and Senate Bill (SB) 626, the CPUC began an Alternative Fuel Vehicles rulemaking to support the widespread deployment and use of plug-in hybrid and electric vehicles (P.U. Code 740.2). In 2013, CPUC continued to develop rules a specific focus on Plug-In Electric Vehicles: 1) to ensure that they efficiently integrate with the utility grid and access fair rates that encourage electrification, and 2) exploring opportunities to finance charging equipment and infrastructure.

Proceeding & Policy History

R.13-11-007: Order Instituting Rulemaking to Consider Alternative-Fueled Vehicle Programs, Tariffs, and Policies

Zero Emission Vehicles (ZEV) Initiative

  • Governor Brown’s Executive Order B-16-2012 set forth several goals related to ZEVs, chiefly to deploy 1.5 million ZEVs on California roads by 2025 and to reduce the State’s transportation-related GHG emissions 80% below 1990 levels by 2050. A subsequent Action Plan identified specific strategies and responsibilities for State agencies in pursuit of the goals. The 2015 ZEV Action Plan will update the state on the Agencies’ progress.
  • CAISO, CEC, and CPUC have worked with stakeholders as directed by the Action plan to develop a Vehicle-Grid Integration Roadmap.
  • Energy Division Presentation to the EVs & The Grid Summit (7/8/15)

R.11-03-012: Order Instituting Rulemaking to address utility cost and revenue issues associated with greenhouse gas emissions.

  • Track 2 of the proceeding regards the use of the IOU’s revenue from the sale of credits generated from CARB’s Low Carbon Fuel Standard Program.

Charging Infrastructure

  • Investor-Owned Utility Charging Infrastructure Deployment
    • The three IOUs each propose to install charging infrastructure to support Governor Brown’s ZEV Action Plan goal to support 1 million Zero-Emission Vehicles by 2020. The proposals, which pend CPUC approval, aim to install infrastructure to support vehicles in multi-unit dwellings, workplaces, and at public interest destinations.

  • CPUC/NRG Settlement  

Vehicle-Grid Integration Research

  • Electric Program Investment Charge internal page (EPIC) Projects, as proposed in Investment Plans subject to approval by the CPUC, will conduct research on how to efficiently integrate Plug-In Electric Vehicles with the utility grid to benefit ratepayers.
