All of the latest updates and decisions related to the Avoided Cost Calculator (ACC) fall under this proceeding. [November 17th, 2022]  
    • D.19-05-019 – Adopts new cost-effectiveness analysis tests for DER programs. Utilizes the Total Resource Cost (TRC) test as the primary test of cost-effectiveness, while also considering the results of the Program Administrator Cost (PAC) and Ratepayer Impact Measure (RIM) cost-effectiveness tests. Lastly, begins testing the Societal Cost Test (SCT) to see if it will help meet California’s carbon reduction objectives. [May 21st, 2019]  
    • D.22-05-002 – Covers the need for continued updates of the Avoided Cost Calculator and the need to align the ACC with the Integrated Resource Planning proceeding. Thus, the ACC will rely upon an adopted Reference System Plan (RSP) or a Preferred System Plan (PSP). [May 6th, 2022] 

Clean Energy Financing Process:

  • Rulemaking R.20-08-022 – The proceeding to investigate and design clean energy financing options for electricity and natural gas customers. [August 27th, 2020]

Energy Efficiency Processes and Systems:

  • D.21-05-031 – Addresses policy issues on the identification of energy efficiency potential and the setting of goals for program administrators to achieve. Adopts the Total System Benefit metric, segments energy efficiency program portfolios into resource acquisition, market support, and equity, and makes changes to the rolling portfolio framework and regulatory process. [May 26th, 2021]
  • D.23-02-002 – Adopts improvements to the third-party solicitation process for the Commission’s energy efficiency portfolio. [February 3rd, 2023]

Custom Project Review (CPR):

CPUC D.09-09-047, D.11-07-030, and the CPR Guidance Page

  • Protect ratepayer funds by ensuring reliable savings estimates. 
  • Customer incentives and program implementer performance payments are based on the estimated efficiency savings.
  • Catch errors that may have escaped the program administrator’s (PA) internal engineering review process to improve the reliability of the efficiency savings estimates. Review items such as:
    • Program influence
    • Efficiency savings calculations methodology
    • Input parameters assumption
    • Savings verification measurement methodologies and data collection
  • Help Program Administrators improve their internal review process.
  • Ensure project compliance with CPUC policy and program rules.

Strategic Energy Management (SEM):

  • SEM was launched in 2018 as an engagement program targeting the industrial & agriculture market sectors (D.16-08-019)
    • Net-to-Gross Ratio of 1
    • Existing Conditions Baseline
    • 5-year Effective Useful Life (EUL)
  • SEM is a holistic, long-term customer engagement using a whole-facility program approach.
  • In SEM, regression models and existing conditions baselines are used to estimate savings from all program activities at the facility.
  • SEM includes capital projects, behavioral, retro-commissioning, and operational (BRO), and integrated demand side management measures.

SEM will be expanded to non-industrial non-residential sectors in the near future pending the completion of an expansion study as directed by D.23-02-002.
