Summary
Xcel Energy Inc. (XEL) announced through its subsidiary, Public Service Company of Colorado (PSCo), a significant regulatory development regarding its Colorado Resource Plan. On December 13, 2023, the Colorado Public Utilities Commission (CPUC) verbally approved an alternative portfolio of 5,835 megawatts (MW) of generation resources, deviating from PSCo's initially proposed "Updated Preferred Plan." This approved alternative portfolio, described as a "no-regrets" decision by the CPUC, prioritizes reliability and cost reduction by incorporating a lower level of renewable generation and a greater amount of storage compared to PSCo's recommendation. The approved portfolio includes 1,700 MW of wind, 1,618 MW of solar, 1,848 MW of storage, and 669 MW of natural gas. PSCo anticipates investing approximately $4.8 billion in these generation resources to meet Colorado's clean energy goals. Notably, the CPUC did not approve a proposed $250 million transmission line, and further deliberations on other aspects of the Resource Plan, such as performance incentive mechanisms, are expected later in December. This decision introduces flexibility for future renewable energy integration, with a "Just Transition Plan" due in the second quarter of 2024.
