2009 Comparison with 2008 — Electric revenues decreased due to lower fuel and purchased power costs, largely due to lower
customer usage and lower commodity prices, lower trading and weather. This was partially offset by retail rate increases in
Colorado, Minnesota, Texas, New Mexico and Wisconsin, higher conservation and non-fuel rider recovery, mostly from the
RESA rider at PSCo and the TCRF rider at SPS.

2009 Comparison to 2008 — The increase in electric margin was due to electric rate increases in Colorado, Minnesota, Texas,
New Mexico and Wisconsin, higher conservation and DSM revenue and non-fuel riders. This was partially offset by higher
purchase capacity costs and a negative impact of weather.
Natural Gas Revenues and Margin
The cost of natural gas tends to vary with changing sales requirements and the cost of natural gas purchases. However, due to the
design of purchased natural gas cost recovery mechanisms to recover current expenses for sales to retail customers, fluctuations in
the cost of natural gas have little effect on natural gas margin. The following tables detail natural gas revenues and margin:
