Clean Energy and Pollution Reduction Act of 2015 (SB 350)

Senate Bill (SB) 350 (de León, Chapter 547, 2015) requires the CPUC to focus energy procurement decisions on reducing greenhouse gas (GHG) emissions by 40 percent by 2030, including efforts to achieve at least 50 percent renewable energy procurement, doubling of energy efficiency, and promoting transportation electrification.

CPUC Implementation Framework

Broad directives provided by SB 350 to the CPUC can be broken down into five major policy areas:

  1. Integrated resource planning
  2. Energy efficiency
  3. Renewable energy
  4. Transportation electrification
  5. Regionalization of electric transmission

Please view our SB 350 Work Area Infographic

Each area requires collaboration with sister state agencies including the California Energy Commission and Air Resources Board. Disadvantaged community goals in SB 350 are cross-cutting and integrated into all of policy areas. Additionally, SB 350 provides policy guidance to the California Independent System Operator on energy market regionalization – a process that requires active engagement by the CPUC.  

The implementation of SB 350 at the CPUC will require multiple and concurrent regulatory proceedings. Please refer to the following table of proceeding timelines to stay up to date on key milestones:

Past workshops

September 26, 2016, 9:30 a.m. – 4:30 p.m., CPUC Auditorium, 505 Van Ness Ave, San Francisco

This workshop will be used to explore in more detail the options for implementing an IRP process, as presented in the CPUC Staff Concept Paper on Integrated Resource Planning, in addition to the issues raised by parties in their August 31st pre-workshop comments. A quorum of Commissioners may attend the workshop, but no votes will be taken.

August 23, 2016, 10:00 a.m. – 4:00 p.m., CPUC Auditorium, 505 Van Ness Ave, San Francisco

California Energy Commission (CEC), CPUC and California Air Resources Board (ARB) jointly hosted a public workshop on the Energy sector on August 23, 2016. This public workshop provided an overview and update on the process to update the 2030 Target Scoping Plan, and will include CEC, CPUC, and ARB staff presentations on current and forthcoming initiatives that contribute to greenhouse gas emissions reductions in the electricity, energy efficiency, and natural gas sectors.

July 26, 2016, 9:00 a.m. - 5:00 p.m., California Secretary of State Auditorium, 1500 11th street, Sacramento

Per the requirements of the Clean Energy and Pollution Reduction Act, Senate Bill 350, the California Public Utilities Commission, California energy Commission and California Air Resources Board jointly hosted a public workshop on July 26, 2016, in Sacramento on topics related to regionalization of the California Independent System Operator, including the development of a governance structure and studies on the environmental and economic impacts of a regional grid operator. 

December 2, 2015, 1:30-4:30 p.m., CPUC Auditorium, 505 Van Ness Ave., San Francisco

The CPUC held a Workshop to initiate a conversation with Commissioners regarding implementation of SB 350 with a focus on the new resource optimization and integrated planning requirements established by Senate Bill (SB) 350 (De León, 2015). SB 350 enacted Public Utilities Code section 454.51, which requires the CPUC to “identify a diverse and balanced portfolio of resources needed to ensure a reliable electricity supply that provides optimal integration of renewable energy in a cost-effective manner.” SB 350 also enacted Public Utilities Code section 454.52, which requires the CPUC to establish an integrated resource planning process for regulated load-serving entities that achieves the State’s greenhouse gas emission reduction target of 40 percent below 1990 levels by 2030 while continuing to deliver safe, reliable, least-cost service to customers. A quorum of Commissioners will be present, but no voting will occur.
