Affordability

Water, energy, and telecommunications services should be affordable. On July 12, 2018, the California Public Utilities Commission (CPUC) issued an Order Instituting Rulemaking (R.18-07-006) to assess the impacts on affordability of individual CPUC proceedings and utility rate requests.

Specifically, the goals of this proceeding are to:

  1. Develop a framework and principles to identify and define affordability criteria for all utility services under CPUC jurisdiction; and
  2. Develop the methodologies, data sources, and processes necessary to comprehensively assess the impacts on affordability of individual CPUC proceedings and utility rate requests.

Within the scope: Issues determined to be within the scope of the proceeding include:

  1. Identification and definition of affordability criteria for CPUC - jurisdictional utility services.
  2. Methods and processes for assessing affordability impacts across Commission proceedings and utility services.
  3. Other issues relating to the CPUC's consideration of the affordability of utility services.

Outside of the scope: Issues determined to be outside the scope include:

  1. Affordability issues related to customer classes other than residential customers.
  2. Evaluation of the effectiveness of existing affordability programs or creation of new customer programs to assess affordability.
  3. New approaches to disconnections and reconnections.
  4. Pacific Gas and Electric Company's Essential Use Study D.18-08-013 issued in PG&E's General Rate Case (GRC).

Background

Californians rely on utility services, including electricity, gas, water, and telecommunications for health, safety, and full participation in society.  The CPUC's commitment to ensuring these services remain affordable and accessible to Californians is articulated in Strategic Directive (SD) 04 on Rates and Affordability and SD 05 regarding Universal Access.

Although the CPUC has regularly considered issues of affordability in a variety of forums, it currently lacks a working definition of what is meant by "affordable," as well as a framework to consistently and comprehensively analyze affordability issues across individual proceedings and utility services.

Part of the challenge in defining and measuring "affordability" is determining the appropriate scale and targeted threshold.  For example, energy burden, the percent of income spend on energy, is one of the simplest metrics used to evaluate affordability.  However, an evaluation of energy burden will yield different results if conducted on a statewide vs. regional level, as results may have different meanings to different geographic populations.  A second challenge in defining affordability is that it is relative to factors that often evolve over time, including utility service rates, customer demand, and other socioeconomic elements.  Some of which are under the purview of the CPUC, but many are not.  Utility rates are effected by infrastructure procurements, commodity costs, reliability and safety requirements, and other operating costs.  Demand for services is effected by geography, climate, household size, and conservation practices.  The ability to pay for utility services often derives from complex socioeconomic factors, such as household income and housing expenditures.

Despite these challenges, the CPUC has developed various affordability metrics that are used to support the decision-making process of many proceedings.  These metrics can be categorized into three classes:

  • Rate impact metrics: These are the most common metrics used by the CPUC to assess affordability of services, and are generally used as part of the general rate case (GRC) process. System Average Rates (SAR) serve as a high-level example of a rate impact metric, but GRCs typically go into more detail to estimate the rate impact for various customer segments.
  • Household-level metrics: These metrics assess the financial impact of utility service on an individual household. Perhaps the most common of these household metrics is the energy burden - the ratio of the cost of the service to the household income. Another household metric that is increasingly discussed is a residual income metric, which is a measure of the income that is left over after paying utility bills.
  • Market-level metrics: Market-level metrics assess the affordability impact to a particular population. The affordability impact of programmatic and tariff design changes fall into this category.

Each of these affordability categories addresses some specific issues, such as setting rates for customer classes, determining strategies to mitigate expenses for low income communities, or evaluating the effectiveness and reach of programs. However, these categories are limited in their scope, and do not necessarily address the challenges related to geographical and socioeconomic factors.  The goal of this Rulemaking is to develop a range of metrics that can provide a comprehensive assessment of residential customers' ability to afford essential utility services.
