HOUSE BILL 23-1252 BY REPRESENTATIVE(S) Lieder and Kipp, Amabile, Bacon, Bird, Boesenecker, Brown, Daugherty, deGruy Kennedy, Dickson, Hamrick, Herod, Joseph, Lindsay, Lindstedt, Lynch, Mabrey, McCormick, McLachlan, Michaelson Jenet, Parenti, Pugliese, Ricks, Snyder, Soper, Story, Taggart, Titone, Valdez, Velasco, Vigil, Willford, Young, McCluskie; also SENATOR(S) Exum and Hansen, Ginal, Mullica, Priola, Sullivan, Winter F. C ONCERNING THE IMPLEMENTATION OF MEASURES TO ADVANCE THERMAL ENERGY SERVICE . Be it enacted by the General Assembly of the State of Colorado: SECTION 1. Legislative declaration. (1) The general assembly finds that: (a) Colorado adopted Senate Bill 21-264, enacted in 2021, that requires regulated gas utilities to develop a clean heat plan to meet a four percent reduction below 2015 greenhouse gas emission levels by 2025 and a twenty-two percent reduction below 2015 greenhouse gas emission levels by 2030; NOTE: This bill has been prepared for the signatures of the appropriate legislative officers and the Governor. To determine whether the Governor has signed the bill or taken other action on it, please consult the legislative status sheet, the legislative history, or the Session Laws. ________ Capital letters or bold & italic numbers indicate new material added to existing law; dashes through words or numbers indicate deletions from existing law and such material is not part of the act. (b) Gas utility workers have helped provide reliable energy throughout the state. Affording gas utilities a pathway to providing thermal energy service in the state also provides gas utility employees an opportunity to utilize many of their existing skills for clean energy jobs for the utility. (c) Colorado residential and business utility customers have been affected by recent trends in gas prices. Helping these utility customers shift from gas to clean thermal energy service could provide long-term price stability for heating and cooling their homes and businesses and for heating water in their homes and businesses. (d) The use of thermal energy networks can help reduce greenhouse gas emissions from buildings and enhance resilience while supporting beneficial electrification. Utility-scale thermal energy projects and investments can especially help the state achieve these goals. (2) The general assembly declares that: (a) Requiring gas utilities to present different approaches for cost recovery of investments in thermal energy service, and requiring the public utilities commission to consider the cost to customers under each approach presented, will help minimize the long-term cost to utility customers for the cost of transitioning to clean thermal energy service; (b) It is important to pursue the decarbonization of buildings in the state in a manner that: (I) Is affordable and accessible; (II) Preserves existing living-wage jobs while also creating new living-wage jobs; and (III) Retains the knowledge and experience of the existing utility union workforce; (c) Passage of this act is intended for the purposes of: (I) Removing the legal barriers to utilities' development of thermal PAGE 2-HOUSE BILL 23-1252 energy networks; (II) Requiring the public utilities commission to evaluate utilities' development of thermal energy networks; and (III) Immediately commencing the piloting of thermal energy network projects by certain utilities; and (d) In evaluating a gas utility's application to provide thermal energy service, the public utilities commission should consider any potential that the utility may have to reuse existing infrastructure that otherwise would result in stranded assets. SECTION 2. In Colorado Revised Statutes, 24-38.5-118, amend (4)(a) introductory portion, (4)(a)(I), (4)(a)(II), (4)(a)(IV), and (4)(c)(II) as follows: 24-38.5-118.
