Energy Source Statistics
## Table 1 ##
(a) This category includes wind energy de-bundled from RECs and also includes Windsource RECs.
Xcel Energy uses RECs to meet or exceed state resource requirements and may sell surplus RECs.
(b) Includes energy from other sources, including solar, biomass, oil and refuse.
Distributed generation from the Solar*Rewards program is not included, and was approximately 266, 222, and 198 million net KWh for 2015, 2014 and 2013, respectively.
NATURAL GAS UTILITY OPERATIONS Overview The most significant developments in the natural gas operations of the utility subsidiaries are uncertainty regarding political and regulatory developments that impact hydraulic fracturing, safety requirements for natural gas pipelines and the continued trend of declining use per residential and small C&I customer, as a result of improved building construction technologies, higher appliance efficiencies and conservation.
From 2000 to 2015, average annual sales to the typical residential customer declined 17 percent, while sales to the typical small C&I customer declined 9 percent, each on a weather-normalized basis.
Although wholesale price increases do not directly affect earnings because of natural gas cost-recovery mechanisms, high prices can encourage further efficiency efforts by customers.
The Pipeline and Hazardous Materials Safety Administration Pipeline Safety Act — The Pipeline Safety, Regulatory Certainty, and Job Creation Act, signed into law in January 2012 (Pipeline Safety Act) requires additional verification of pipeline infrastructure records by pipeline owners and operators to confirm the maximum allowable operating pressure of lines located in high consequence areas or more-densely populated areas.
The DOT Pipeline and Hazardous Materials Safety Administration (PHMSA) will require operators to re-confirm the maximum allowable operating pressure if records are inadequate.
This process could cause temporary or permanent limitations on throughput for affected pipelines.
In addition, the Pipeline Safety Act requires PHMSA to issue reports and develop new regulations including: requiring use of automatic or remote-controlled shut-off valves; requiring testing of certain previously untested transmission lines; and expanding integrity management requirements.
The Pipeline Safety Act also raises the maximum penalty for violating pipeline safety rules to $2 million per day for related violations.
While Xcel Energy cannot predict the ultimate impact Pipeline Safety Act will have on its costs, operations or financial results, it is taking actions that are intended to comply with the Pipeline Safety Act and any related PHMSA regulations as they become effective.
PSCo and NSP-Minnesota can generally recover costs to comply with the transmission and distribution integrity management programs through the PSIA and GUIC riders, respectively.
Income tax expense increased $39.8 million for 2014 compared with 2013.
The increase was primarily due to higher 2014 pretax earnings and recognition of additional R&E credits in 2013.
These were partially offset by a 2014 tax benefit for prior year adjustments.
The ETR was 33.9 percent for 2014 compared with 33.8 percent for 2013.
See Note 6 to the consolidated financial statements for further discussion.
Xcel Energy Inc.  and Other Results The following tables summarize the net income and EPS contributions of Xcel Energy Inc.  and its nonregulated businesses:
## Table 2 ##
Contribution to Xcel Energy’s EPS
## Table 3 ##
(a) Amounts include gains or losses associated with sales of properties held by Eloigne.
Xcel Energy Inc. ’s results include interest charges, which are incurred at Xcel Energy Inc.  and are not directly assigned to individual subsidiaries.
Factors Affecting Results of Operations Xcel Energy’s utility revenues depend on customer usage, which varies with weather conditions, general business conditions and the cost of energy services.
Various regulatory agencies approve the prices for electric and natural gas service within their respective jurisdictions and affect Xcel Energy’s ability to recover its costs from customers.
The historical and future trends of Xcel Energy’s operating results have been, and are expected to be, affected by a number of factors, including those listed below.
General Economic Conditions Economic conditions may have a material impact on Xcel Energy’s operating results.
While economic growth has been improving over the past year, management cannot predict whether this trend will be sustained going forward.
Other events impact overall economic conditions and management cannot predict the impact of fluctuating energy prices, terrorist activity, war or the threat of war.
However, Xcel Energy could experience a material impact to its results of operations, future growth or ability to raise capital resulting from a sustained general slowdown in economic growth or a significant increase in interest rates.
Fuel Supply and Costs Xcel Energy Inc. ’s operating utilities have varying dependence on coal, natural gas and uranium.
Changes in commodity prices are generally recovered through fuel recovery mechanisms and have very little impact on earnings.
However, availability of supply, the potential implementation of a carbon tax or emissions-related generation restrictions and unanticipated changes in regulatory recovery mechanisms could impact our operations.
See Item 1 for further discussion of fuel supply and costs.
Pension Plan Costs and Assumptions Xcel Energy has significant net pension and postretirement benefit costs that are measured using actuarial valuations.
Inherent in these valuations are key assumptions including discount rates and expected return on plan assets.
Xcel Energy evaluates these key assumptions at least annually by analyzing current market conditions, which include changes in interest rates and market returns.
Changes in the related net pension and postretirement benefits costs and funding requirements may occur in the future due to changes in assumptions.
The payout of a significant percentage of pension plan liabilities in a single year due to high retirements or employees leaving the company would trigger settlement accounting and could require the company to recognize material incremental pension expense related to unrecognized plan losses in the year these liabilities are paid.
For further discussion and a sensitivity analysis on these assumptions, see “Employee Benefits” under Critical Accounting Policies and Estimates.
