(a) Notwithstanding the requirements in paragraph 4729(d), a small gas distribution
utility may file a clean heat plan to meet greenhouse gas emission reductions
targets for 2025 and 2030 pursuant to this rule 4734. Such utilities then shall file
additional clean heat plans in accordance with the clean heat plan rules,
comprising rules 4725 through 4733, unless otherwise directed by the
Commission.
(b) A clean heat plan filed in accordance with this rule 4734 must:
(I) propose greenhouse gas emission reduction targets for years 2025 and
2030;
(II) identify the clean heat resources to be used to reduce emissions on its
system during the clean heat plan action period;
(III) quantify the annual greenhouse gas emission reductions expected during
action plan period in total and for each clean heat resource calculated
pursuant to rules 4525 through 4528;
(IV) propose program budgets, disaggregated by each clean heat resource, to
meet the proposed greenhouse gas emission reduction targets; and
(V) quantify the cost of the clean heat resources and other actions to reduce
greenhouse gas emissions during the plan period and demonstrate that
such costs satisfy the analysis of the annual retail bill impact in
accordance with § 40-3.2-108.6(a)(I), C.R.S.
(c) A clean heat plan filed in accordance with this rule 4734 may solicit clean heat
resources through a competitive solicitation as set forth in paragraph 4731(f).
(d) The Commission shall approve a clean heat plan submitted under this rule 4734
if the Commission finds it to be in the public interest. The Commission may
modify the clean heat plan if modifications are necessary to ensure that the plan
is in the public interest. In evaluating whether the plan is in the public interest, the
Commission shall consider the factors in paragraph 4732(b) and the annual retail
cost impact in accordance with § 40-3.2-108.6(a)(I), C.R.S.
(e) The small gas distribution utility whose clean heat plan is approved by the
Commission in accordance with this rule 4734 shall submit the annual clean heat
plan reports required in rule 4733.
