Item 8.01. Other Events

Colorado Energy Plan
In 2016, Public Service Company of Colorado (PSCo), a Colorado corporation and wholly owned subsidiary of Xcel Energy Inc. (Xcel Energy), filed its 2016 Electric Resource Plan (ERP) which included the estimated need for additional generation resources through spring of 2024. In 2017, PSCo filed an updated generation capacity need with the Colorado Public Utilities Commission (CPUC) of 450 megawatts (MW) in 2023.

In 2017, PSCo and various other stakeholders filed a stipulation agreement proposing the Colorado Energy Plan (CEP), an alternative electric resource plan that increased PSCo’s firm generation capacity need up to 1,110 MW due to the proposed retirement of two coal units, Comanche Unit 1 (in 2022) and Comanche Unit 2 (in 2025).

In June 2018, PSCo filed a regulatory update with the CPUC which included detailed analysis of multiple electric generation portfolio options and included a recommended preferred CEP portfolio and an alternative CEP portfolio for the CPUC's approval. The preferred CEP portfolio included the following additions as well as the retirement of the two coal-fired generation units:
Total Capacity
PSCo's Ownership
Wind generation
1,100 MW
500 MW

Solar generation
700 MW

Battery storage
275 MW

Natural gas generation
380 MW
380 MW

On Aug. 27, 2018, the CPUC voted for preliminary approval of PSCo's preferred CEP. A written order is expected in September.

PSCo's investment under the preferred CEP portfolio would be approximately $1 billion, including investment in required transmission to support the significant increase in renewable generation in the state.

Xcel Energy plans to fund the incremental $1 billion of capital investment with cash from operations, incremental debt and $300 million to $400 million of incremental equity, primarily in 2020 and beyond.

Certain information discussed in this Current Report on Form 8-K is forward-looking information that involves risks, uncertainties and assumptions. Forward-looking information includes, among other information, the expected impact of PSCo’s Colorado Energy Plan, and other statements identified by words such as “may,” “believe,” “expect,” “estimate,” “anticipate,” “would,” or “plan.” Forward-looking statements are subject to certain risks, uncertainties and assumptions. Although Xcel Energy believes that its expectations are based on reasonable assumptions, any such statements may be influenced by factors that could cause actual outcomes and results to be materially different from those projected. Factors, in addition to those discussed in Xcel Energy’s and PSCo’s Annual Report on Form 10-K for the year ended Dec. 31, 2017, and subsequent securities filings, that could cause actual results to differ materially include: general economic conditions, including inflation rates, monetary fluctuations and their impact on capital expenditures and the ability of Xcel Energy Inc. and its subsidiaries (collectively, Xcel Energy) to obtain financing on favorable terms; business conditions in the energy industry; including the risk of a slow down in the U.S. economy or delay in growth recovery; trade, fiscal, taxation and environmental policies in areas where Xcel Energy and PSCo have a financial interest; customer business conditions; actions of credit rating agencies; competitive factors including the extent and timing of the entry of additional competition in the markets served by Xcel Energy and its subsidiaries; unusual weather; effects of geopolitical events, including war and acts of terrorism; cyber security threats and data security breaches; state, federal and foreign legislative and regulatory initiatives that affect cost and investment recovery, have an impact on rates or have an impact on asset operation or ownership; or impose environmental compliance conditions; structures that affect the speed and degree to which competition enters the electric and natural gas markets; costs and other effects of legal and administrative proceedings, settlements, investigations and claims; financial or regulatory accounting policies imposed by regulatory bodies; outcomes of regulatory proceedings; availability or cost of capital; and employee work force factors. Forward-looking statements speak only as of the date they are made, and Xcel Energy expressly disclaims any obligation to update any forward-looking information.
