Why am I receiving this notice?

Senate Bill 846 was signed into law in September 2022, providing a path to extend DCPP operations beyond the current operating licenses, which are set to expire in 2024 and 2025.

Included in the legislation is the requirement that new retirement dates be set by the end of calendar year 2023.

How could this affect my monthly bill?

After current operating licenses expire, DCPP will be used to support California statewide electricity customers. Any costs associated with the extension of operations will be included in rates for all load serving entities in California, including customers in the service territories of Bear Valley Electric Service Inc., Liberty Utility (CalPeco Electric) LLC, PacifiCorp, Southern California Edison Company and San Diego Gas & Electric Company.

The CPUC will open a new proceeding for all California electric utilities to address the impact to rates. More information will be provided to customers when it is available.

 How does the rest of this process work?

This proceeding has been assigned to a CPUC Administrative Law Judge who will consider proposals and evidence presented during the formal hearing process.

The Administrative Law Judge will issue a proposed decision that may adopt, modify or deny parties’ proposals. Any CPUC Commissioner may sponsor an alternate decision with a different outcome. The proposed decision, and any alternate decisions, will be discussed and voted upon by the CPUC Commissioners at a public CPUC Voting Meeting.

Parties to the proceeding will review the proceeding, including the Public Advocates Office. The Public Advocates Office is an independent consumer advocate within the CPUC that represents customers to obtain the lowest possible rate for service consistent with reliable and safe service levels.
