Our Just Transition Solicitation (JTS) (PDF) is a multi-year process to identify up to 2,000 megawatts of new energy resources needed to replace retiring coal units and serve Colorado's growing energy needs — while supporting our workforce and local communities.
We filed Phase 1 of the JTS in October 2024, and the Colorado Public Utilities Commission issued its final written approval (PDF) in November 2025. Phase 1 did not include specific power projects. Instead, it established the framework, assumptions and bid evaluation criteria that will guide the competitive solicitation process during Phase 2.
In August 2026, we launched the Phase 2 request for proposals (RFP), inviting developers to submit bids for energy projects that can help meet customers’ needs through 2031. We’re seeking proposals for a variety of resources — including wind, solar, energy storage, natural gas-fired generation and other eligible technologies. We will evaluate bids and submit potential resource portfolios to the commission in early 2027 as part of the Phase 2 Report. The commission will ultimately decide which projects move forward for development and construction.
