Summary
Xcel Energy Inc. (XEL) subsidiary Public Service Company of Colorado (PSCo) has filed an update report regarding its proposed Colorado Energy Plan (CEP) with the Colorado Public Utilities Commission (CPUC). The CEP aims to significantly shift the state's energy generation towards renewables and storage, including the early retirement of two coal-fired units (Comanche Units 1 and 2) by 2022 and 2025, respectively. This plan involves substantial investment in new generation resources, with PSCo's preferred portfolio projecting a total investment of $2.5 billion in generation and battery storage, of which PSCo would own approximately $1 billion. The updated filing outlines multiple portfolio scenarios, with a preferred option that includes 1,100 MW of wind, 700 MW of solar, and 275 MW of battery storage, alongside 380 MW of natural gas generation. The plan also proposes a reduction in the renewable energy standard adjustment rider (RESA) and aims for significant ownership targets of renewable and storage resources. A final decision from the CPUC is anticipated by September 2018, which will be crucial for Xcel Energy in understanding the financial and operational implications of this strategic shift.
Key Highlights
