California Code, Public Utilities Code - PUC § 2774.1

(a)(1) The commission shall require an electrical corporation to include in an annual reliability report, required pursuant to Decision 96-09-045, as amended, or a decision that supersedes Decision 96-09-045, information on the reliability of service to end use customers that identifies, but is not limited to, the frequency and duration of interruptions in services.  This information shall indicate areas with both the most frequent and longest outages, using local areas determined by the commission.  The commission, in consultation with the electrical corporation, shall ensure that the geographical boundaries of local areas do not split up circuits for reporting purposes, if the electrical corporation aggregates data by circuits.  The information shall be sufficiently aggregated to both maintain electrical system security, and be of use and relevance to affected customers of the electrical corporation.

(2) Before July 1, 2014, the commission shall determine the local areas for the purposes of paragraph (1).

(3) The requirements of paragraph (1) shall apply to annual reports due after July 1, 2014.

(4) The electrical corporation shall conspicuously post on its Internet Web site the annual report required pursuant to Decision 96-09-045, as amended, or a decision that supersedes Decision 96-09-045.

(b)(1) The commission shall use the information contained in an electrical corporation's annual reliability report to require cost-effective remediation of reliability deficiencies if the report, or more than one report, identifies repeated deficiencies in the same local area as determined by the commission pursuant to paragraph (1) of subdivision (a).  In requiring cost-effective remediation, the commission shall consult with the electrical corporation and consider mitigating factors that may impede an electrical corporation from implementing required cost-effective remediation, including, but not limited to, local permitting matters or other events or conditions or public policy considerations that may present higher priority safety or reliability issues.

(2) The commission may suspend the requirements of paragraph (1) if the commission finds that expenditures by the electrical corporation to comply with that paragraph are not justified or that the remediation measures undertaken by the electrical corporation are not effective at improving reliability.

(c)(1) The commission may order an electrical corporation to make more frequent trend analyses of local area service reliability and to make those analyses publicly available.

(2) The information made publicly available shall provide sufficient confidentiality for purposes of protecting electrical system security.

(3) The commission may make those analyses publicly available.
