Electric Fuel and Purchased Power - Expenses incurred for electric fuel and purchased power are impacted by fluctuations in market prices of natural gas and coal, as well as seasonality. These incurred expenses are generally recovered through various regulatory recovery mechanisms. As a result, changes in these expenses are largely offset in operating revenues and have minimal earnings impact.
Electric fuel and purchased power expenses decreased $96 million year-to-date. The decrease was primarily due to lower volumes and timing of fuel recovery mechanisms.
Cost of Natural Gas Sold and Transported - Expenses incurred for the cost of natural gas sold are impacted by market prices and seasonality. These costs are generally recovered through various regulatory recovery mechanisms. As a result, changes in these expenses are largely offset in operating revenues and have minimal earnings impact.
Natural gas sold and transported decreased $72 million year-to-date. The decrease was primarily due to decreased volumes.
Non-Fuel Operating Expenses and Other Items
O&M Expenses - O&M expenses increased $13 million year-to-date, largely due to higher wildfire mitigation costs.
Depreciation and Amortization - Depreciation and amortization expense increased $85 million year-to-date. The increase was primarily due to system investment.
AFUDC, Equity and Debt - AFUDC increased $130 million year-to-date, largely due to system investment.
Interest Charges - Interest charges increased $97 million year-to-date, largely due to increased long-term debt levels and higher interest rates.

Public Utility Regulation and Other
|
The FERC and state and local regulatory commissions regulate PSCo. PSCo is subject to rate regulation by state utility regulatory agencies, which have jurisdiction with respect to the rates of electric and natural gas distribution companies in Colorado.
Rates are designed to recover plant investment, operating costs and an allowed return on investment. PSCo requests changes in utility rates through commission filings. Changes in operating costs can affect PSCo's financial results, depending on the timing of rate cases and implementation of final rates. Other factors affecting rate filings are new investments, sales, conservation and demand side management efforts and the cost of capital.
In addition, the regulatory commissions authorize the ROE, capital structure and depreciation rates in rate proceedings. Decisions by these regulators can significantly impact PSCo's results of operations.
Except to the extent noted below, the circumstances set forth in Public Utility Regulation included in Item 7 of PSCo's Annual Report on Form 10-K for the year ended Dec. 31, 2025, appropriately represent, in all material respects, the current status of public utility regulation and are incorporated herein by reference.
Pending and Recently Concluded Regulatory Proceedings
2025 Colorado Electric Rate Case - In November 2025, PSCo filed an electric rate case with the CPUC seeking an increase in revenue of $356 million (9.9%) ($526 million inclusive of rider roll-ins). The request is based on a 9.8% ROE, an equity ratio of 55% and a 2025 test year with a projected rate base of $13 billion.
In June 2026, PSCo, CPUC Staff and various other parties filed a comprehensive non-unanimous settlement agreement. The AARP, City of Boulder and the UCA opposed the settlement. Other parties either supported portions of the settlement or did not oppose it.
PSCo received a final decision from the CPUC in September 2026. Terms of the final decision include:
•Revenue increase (excluding rider roll-ins) of $184 million (5.2% total, or an annual average of 1.7% since the last rate case), based on a 2025 historical test year using a 13-month average.
•ROE of 9.3% and equity ratio of 54.5%.
•A performance framework applicable to the operation of Comanche Unit 3 coal facility from effective date of rates through 2029. PSCo also agreed to file a prudence review related to the outage at the unit (from August 2025 to September 2026) in June 2027.
•Continuation of previously authorized trackers and deferrals.
2025 Colorado Natural Gas Rate Case - In December 2025, PSCo filed a natural gas rate case with the CPUC seeking an increase in revenue of $190 million (11.6%). The request is based on a 10.75% ROE, an equity ratio of 55% and a 2025 test year with a projected rate base of $4.7 billion.
In July 2026, PSCo, CPUC Staff, the UCA, the Colorado Energy Office, Western Resource Advocates/Sierra Club, Energy Outreach Colorado and various other parties filed a comprehensive non-unanimous settlement agreement. Several parties either do not oppose or take no position on the settlement, and one transportation shipper opposes it. Key terms of the settlement include:
•Revenue increase of $123 million (7.5% total, or an annual average of 3.7% since the last rate case), based on a 2025 historic test year using a 13-month average rate base with forward looking known and measurable adjustments.
•ROE of 9.2% and equity ratio of 54.5%.
