Understanding Your Rate Identification Number (RIN)

What Is a Rate Identification Number (RIN)?

As of April 1, 2024, California utilities are required to include a Rate Identification Number (RIN) on customer energy bills. A RIN is a unique identifier created by the California Energy Commission (CEC) to support time-of-use pricing plans. It allows customers to access hourly electric pricing data.

How the RIN Works​

The RIN is based on electric rate schedules and is not tied to individual customers. If you’re a Community Choice Aggregator (CCA) customer with San Diego Community Power, your energy bill includes two separate RINs:

  • One RIN for your Community Power Electric Generation
  • One RIN for your SDG&E Electric Delivery (located in the Electric Delivery section of your SDG&E bill)

Why the RIN Matters

The RIN is designed to help you better understand your energy usage and billing. By knowing your specific RIN, you can download detailed hourly pricing data directly from the California Energy Commission’s website.
