# Approval of a Clean Heat Plan **Citation:** 4 CCR 723-4 Rule 4732 **Type / status:** regulation / current **Agency:** Colorado Public Utilities Commission **Effective:** Not stated **Published:** Not stated (a) The Commission shall approve a clean heat plan, including the associated forecasts set forth in paragraph 4731(b), if it finds the plan to be in the public interest. The Commission may modify the plan if the modifications are necessary to ensure the plan is in the public interest. (b) In evaluat ## Document text (a) The Commission shall approve a clean heat plan, including the associated forecasts set forth in paragraph 4731(b), if it finds the plan to be in the public interest. The Commission may modify the plan if the modifications are necessary to ensure the plan is in the public interest. (b) In evaluating whether the clean heat plan is in the public interest, the Commission shall consider, at a minimum, the following factors: (I) whether the plan achieves the clean heat targets using clean heat resources that, in aggregate, maximize greenhouse gas emission reductions; (A) The Commission shall consult with the Air Pollution Control Division to estimate reductions of emissions of greenhouse gases and other air pollutants under the portfolios and verify the utility’s calculations. (B) The Air Pollution Control Division may participate as a party in the proceeding in which a utility files for approval of a clean heat plan. (II) whether the plan can be implemented at the lowest reasonable cost and rate impact, taking into account savings to customer bills resulting from investments made pursuant to the plan. In determining the reasonableness of the cost and the cost impact, the Commission shall consider: (A) fuel costs; (B) non-fuel direct investment associated with the clean heat plan; (C) gas infrastructure costs; (D) gas system operation costs; (E) a cost test that includes both the social cost of carbon and the social cost of methane; and (F) any other costs and benefits found relevant by the Commission. (III) whether the plan provides additional air quality, environmental, and health benefits in addition to the greenhouse gas emission reductions, and otherwise supports environmental justice goals; (IV) whether the utility has demonstrated the investments in the clean heat plan prioritize serving customers participating in income-qualified programs and communities historically impacted by air pollution and other energy-related pollution; (V) whether the plan presents risks to the utility’s customers, including the risk of market volatility and the risk of stranded investment costs; (VI) whether the plan provides long-term impacts on Colorado’s utility workforce as part of a just transition including consideration of the labor metrics and benefits as specified in § 40-3.2-108(8), C.R.S., and defined in paragraph 4001(j); and (VII) whether the plan maintains system safety and reliability. (c) The Commission may approve a utility’s proposed rate adjustment clause or structure that allows for current recovery of the utility’s clean heat plan costs. (d) The utility may recover the prudently incurred costs associated with actions under an approved clean heat plan or other actions to meet any additional emission reduction requirements imposed on the utility pursuant to § 25-7- 105(l)(e), C.R.S. (e) In evaluating clean heat plans addressing emission reductions to meet clean heat targets after 2030, the Commission will approve recovered methane resources only where the Commission finds that inclusion of the recovered methane resources in the approved portfolio furthers investment in Colorado communities, reduces greenhouse gas emissions, is cost-effective, and is in the public interest. ## Provenance - Official: Yes - Source: - Source ID: `co-sos-ccr` - SHA-256: `b6c3f8dc0b4c4eef97da74f277fdb8cbbf282700e51e1f2ebe33078619fc3749` - Retrieved: 2026-08-12T04:36:48.096Z - Exported: 2026-08-22T22:04:48.625Z - Document slug: `co-ccr-4-723-4-4732` ### Source metadata ```json { "jurisdiction": "US-CO", "code": "4 CCR 723-4", "ruleKey": "4732", "pipelineScope": "colorado-jurisdictional-gas-utilities", "legalScope": "Current 4 CCR 723-4 rules regulating Colorado jurisdictional gas utilities and gas master-meter operators, including construction, operation, system safety, gas infrastructure planning, metering, service, and enforcement provisions.
