(a) The revenue requirement for each year or, with respect to the first year and last year, the pro rata portion of the year, shall be equal to the average annual amount of collections by the department with respect to charges imposed pursuant to the revenue requirements established by the department under Section 80110 for the period from January 1, 2013, through December 31, 2018. The revenue requirement shall remain in effect until January 1, 2036.

(b) If, pursuant to Section 3289 of the Public Utilities Code, the commission makes a just and reasonable determination with respect to the revenue requirement, then the commission shall enter into an agreement with the department with respect to charges under Section 3289 of the Public Utilities Code with respect to the revenue requirement, and that agreement shall have the force and effect of an irrevocable financing order adopted in accordance with Article 5.5 (commencing with Section 840) of Chapter 4 of Part 1 of Division 1 of the Public Utilities Code, as determined by the commission. The agreement and financing order shall provide for the administration of the revenue requirement, including provisions to the effect that (1) the department shall notify the commission each year of the annual collections received by the department with respect to the revenue requirement and the amount of any excess or deficiency in collections above or below the revenue requirement and that the commission shall adjust charges in the subsequent year to reflect any such excess or deficiency, and (2) during any revenue requirement period if the department forecasts that the revenue requirement for that period will not be met and that collections will not be sufficient to fund any of the amounts in paragraphs (1) to (5), inclusive, of Section 80544, then the department shall notify the commission in writing and the commission shall act within 30 days to increase charges so that the amounts collected during that period are sufficient to meet those obligations. For avoidance of doubt, no such adjustment to charges by the commission shall affect in any respect the commission’s just and reasonable determination with respect to the revenue requirement.

(Amended by Stats. 2019, Ch. 396, Sec. 55. (AB 1513) Effective January 1, 2020.)
