 WASTE WATER TREATMENT PLANT  ST. PAUL, MINNESOTA Our portfolio of wind energy is a good  example. Xcel Energy is the No. 1 provider  of wind power in the nation, with about  4,100 megawatts on our system at the end  of 2011. We are fortunate to have plentiful  wind resources in our service territory, and  we took advantage of those resources early.  Even more important, we added that wind  power at a competitive price, making wind  a reasonable hedge against volatile natural  gas prices. We like to say that we build at the speed of value. That means we take a disciplined approach to adding  renewable resources, making sure our  customers reap the benefits both financially and environmentally.  Our clean, reliable nuclear plants also  provide value. In 2011, the Nuclear  Regulatory Commission (NRC) extended  the operating licenses of both units at our  Prairie Island nuclear plant for 20 years. The NRC previously extended the operating  license of our Monticello plant. We are  awaiting NRC approval of our proposal  to increase generating capacity at the  Monticello plant and plan to complete the  upgrade in the spring of 2013 if approved.  Meanwhile, we are asking the Minnesota  Public Utilities Commission to reconfirm  our plan to increase generating capacity at  Prairie Island due to recent developments  XCEL ENERGY  ! . . 5 ! , 2 % 0 / 2 4 s
