Energy General Rate Cases

General Rate Case (GRC) proceedings currently take place every three years before the Commission. The GRC will set the base revenue requirements for electric/gas operations.  These base revenues recover the utility's operation and maintenance expenses, depreciation, and taxes and provide a return on invested capital.

The Public Advocates Office participates in GRCs on behalf of customers of California's investor owned utilities.



General Rate Case Plan Reform 

In November 2013, the CPUC opened a new Rulemaking to consider changes to both the General Rate Case (GRC) Plan and to consider how to incorporate risk-based decision-making into General Rate Cases for electricity and gas utilities.


Risk Assessment Mitigation Phase (RAMP)

Starting in 2016, California’s large energy utilities are required to file a Risk Assessment Mitigation Phase (RAMP) with the CPUC one year prior to their General Rate Cases. The RAMP will examine utilities’ safety and safety-spending priorities in advance of their GRCs.

Safety Model Assessment Proceeding (S-MAP)

The purpose of the S-MAP is to develop policies and guidelines for utility models that will be used to prioritize programs/projects intended to mitigate risks in utility operations. The S-MAP serves as the foundation to the CPUC’s Risk Assessment Mitigation Phase (RAMP), which will precede utilities’ General Rate Case (GRC) filings.
