(a) Extreme weather variations and additional factors such as windchill and cloud cover may not be reflected in weather-normalized and actual growth estimates.
Weather-normalized Electric 2015 Growth (Decline)
• PSCo’s residential growth was primarily the result of customer additions, partially offset by lower use per customer.
Commercial and industrial (C&I) decline was primarily due to reduced sales to certain large manufacturing customers and/or
those that support the fracking industry.
• NSP-Minnesota’s residential decrease was due to lower use per customer, partially offset by an increase in customer
additions. C&I electric sales decreased as a result of lower use by large and small customers (e.g., services, retail trade,
finance insurance and real estate industries), partially offset by higher use by certain large customers in the petroleum and
food processing industries. The decline was partially reduced by an increase in the number of customers in both the small
and large classes.
• SPS’ residential growth reflects an increased number of customers. C&I also had an increase in customers, primarily in the
oil and gas exploration and production industries. However, this was partially offset by reduced activity per customer within
these industries, as well as less irrigation by agricultural customers due to wet weather.
• NSP-Wisconsin’s residential decline was primarily attributable to lower use per customer, partially offset by customer
additions. C&I electric sales growth was largely due to strong sales to large customers primarily in the oil and gas industries.
Weather-normalized Natural Gas 2015 Decline
• Across natural gas service territories, lower natural gas sales reflect a decline in customer use.
Weather-normalized sales for 2016 are projected to increase approximately 0.5 percent to 1.0 percent for retail electric customers and
remain relatively flat for retail firm natural gas customers.
