4 Colo. Code Regs. § 723-3-3526
The purpose of these rules, as directed by § 40-2-132, C.R.S., is to require electric utilities to file a Distribution System Plan (DSP) that enables the Commission to review and evaluate the utility's investments in the distribution grid to ensure that they cost-effectively support grid adequacy, reliability and resilience and prepare for new expectations upon the distribution system, while simultaneously ensuring progress toward priorities highlighted by state legislation, including but not limited to supporting diversification of energy supply through distributed energy resources, expanding the utilization of non-wire alternatives that may reduce the need for conventional distribution grid investment, reducing greenhouse gas emissions, advancing building and transportation electrification, maintaining affordable customer rates, and promoting equity with regard to disproportionately impacted communities. These rules should also establish a proactive and transparent process for enhancing understanding of key distribution system characteristics.
