What is the main impact of this filing for Xcel Energy investors?

This filing signals a faster transition to cleaner energy sources for Xcel Energy's Colorado subsidiary, PSCo. While this accelerates carbon emission reductions and aligns with ESG goals, it also involves managing the financial aspects of retiring older assets and investing in new resources. Investors should monitor the cost recovery mechanisms and the impact on future capital expenditures and operational efficiency.

How will the accelerated coal plant retirements affect PSCo's operational costs and reliability?

The accelerated retirements and conversion to natural gas will necessitate significant investments in new renewable and dispatchable resources to replace the lost capacity and energy. PSCo plans to recover these costs through regulatory mechanisms. While the new resources are cleaner, the transition period and integration of new technologies could present operational challenges and initial cost increases. Reliability is expected to be maintained through the addition of flexible dispatchable resources and storage.

What is the proposed method for recovering the costs associated with retiring the Comanche 3 and Pawnee plants?

PSCo plans to maintain current depreciation levels for Comanche 3 and recover the remaining balance upon retirement, potentially through securitization pending CPUC approval. For the Pawnee plant conversion, costs will be recovered through a regulatory asset with a full weighted average cost of capital return. Costs for the Hayden power plant will be recovered over their original depreciation lives within PSCo’s pending electric rate case. The incremental costs for meeting carbon reduction targets are proposed to be recovered via a Clean Energy Plan Rider.

When can investors expect a final decision on this Electric Resource Plan?

A decision from the Colorado Public Utilities Commission (CPUC) on the resource plan is anticipated in the first half of 2022. Following this decision, the competitive solicitation for resource additions is expected in the second half of 2022.

Summary

Xcel Energy Inc.'s subsidiary, Public Service Company of Colorado (PSCo), has reached a partial settlement with intervenors regarding its 2021 Electric Resource Plan. The settlement proposes significant acceleration of coal plant retirements and conversions, aiming for an 87% carbon emissions reduction by 2030 (from 2005 levels), surpassing the initial target. Key changes include retiring the Comanche 3 coal plant by December 31, 2034, with phased reductions starting in 2025, and converting the Pawnee coal plant to natural gas by January 1, 2026, with retirement in 2041. Renewable and other clean energy additions remain consistent in scale but are expected to be acquired earlier to compensate for the reduced coal plant operations.

Key Highlights

1The partial settlement significantly accelerates the retirement of the Comanche 3 coal plant to December 31, 2034, with phased reductions in operations beginning in 2025.
2The Pawnee coal plant is now slated for conversion to natural gas by January 1, 2026, with an eventual retirement in 2041.
3The revised plan targets an 87% reduction in carbon emissions by 2030 (compared to 2005 levels), exceeding the initial goal of 85%.
4Renewable energy (wind and solar) and storage additions remain substantial, with earlier acquisition anticipated.
5PSCo will own at least $626 million in capital investment equivalent to the estimated net book value of Comanche 3 at retirement.
6The company proposes recovery mechanisms for coal plant assets through regulatory assets, securitization (pending approval), and existing rate cases to manage costs associated with the transitions.
