COMPANY AND WORKFORCE

Workforce Totals by Job Classification and State (as of year-end 2016)

The following table includes all full-time, part-time and temporary employees of Xcel Energy, but excludes contractors and employees on leaves of absence. It breaks down our workforce by state and by main job categories. Bargaining employees are full-time, permanent employees covered under collective bargaining agreements. Craft employees are temporary, project-specific employees also covered by collective bargaining agreements. Both bargaining and craft employees are combined to make up the percent of our workforce represented by unions. Non-bargaining employees consist of management and non-management employees based on the type of work they perform.

community and volunteer events.

Employee Volunteer Hours are provided for those programs that we have a system in place for tracking, which include Volunteer Paid Time Off,

Dollars-for-Doing, Volunteer Energy and Day of Service. Actual employee volunteer hours are greater than reported here because the company

promotes and sponsors a number of employee volunteer activities in addition to the programs we track.

Volunteer Matching Dollars includes company payments to community organizations through Dollars-for Doing and Volunteer Energy.

Disaster Relief includes corporate contributions to the Red Cross and similar organizations, as well as funds donated on behalf of customers

2016 Xcel Energy Tax Payments by State

Xcel Energy annually pays significant property and sales taxes that support local governments and pay for community services. In many small

communities, we are the largest tax payer.

2016 City Franchise Agreements

Xcel Energy has franchise agreements with some of the cities and towns where we provide natural gas and electricity service. These agreements

give us rights to use the municipality’s alleys, streets and rights-of-way so we can, for example, run power lines along city property. As part of

some of the franchise agreements, we collect a fee from our customers and pay that money to the cities and towns. The franchise fee is not a tax

but rather a portion of the cost to operate a utility.

2016 Electric Transmission and Distribution Line Loss

Xcel Energy calculates electric line losses in accordance with The Climate Registry’s Electric Power Sector Protocol using method IE-01. Using this methodology, transmission and distribution losses were calculated to be 2.7 percent for 2016.

2016 Xcel Energy Reliability Results We measure electric system reliability through three indexes, using methodology provided by the Institute of Electrical and Electronics Engineers (IEEE). The methodology is commonly used in our industry and incorporating it improves our ability to benchmark Xcel Energy’s performance with other utilities. The System Average Interruption Duration Index (SAIDI) measures the average number of minutes a typical customer was without power in a year. The System Average Interruption Frequency Index (SAIFI) measures the average number of power outages that an average customer experienced in a year. The Customer Average Interruption Duration Index (CAIDI) measures the length of the average power outage in a year.

Methodology

In this report, we include emissions from the electricity that we produce and that we purchase from third-party suppliers. A system emission rate is included for each year that provides the pounds of carbon emissions produced for each megawatt hour of electricity supplied. Emissions for 2016 are preliminary, and may slightly change during third-party verification, which should be completed by the end of 2017.

To provide transparent and complete emissions information for customers, we report biogenic carbon dioxide from biomass generation, as well as emissions from fossil fuel generation. We consider biogenic carbon emissions effectively neutral, since compared to fossil fuels, these emissions from biomass combustion are part of a relatively short-term cycling of carbon dioxide between ecosystems and the atmosphere.

Third-party assurance and verification

We recognize the value of having a formal emissions protocol and completing third-party verification for emissions reporting. In 2007, we became a founding member of The Climate Registry, a nonprofit organization established to provide consistent and transparent standards for calculating, verifying and reporting greenhouse gas emissions into a single registry for North America. All of our greenhouse gas emissions from 2005 to 2015 have been third-party verified and registered with The Climate Registry.

Other emissions reporting

Xcel Energy publicly reports annual carbon dioxide emissions, as well as other greenhouse gases, through a number of different reporting programs, including The Climate Registry, CDP and the U.S. Environmental Protection Agency’s mandatory greenhouse gas reporting rule. These programs each use a unique reporting protocol and may represent emissions differently. While reporting protocols and formats vary, the information we provide comes from the same foundation data.
