Xcel Energy, with 4,897 megawatts on its system overall (both wind energy PPAs and utility-owned projects).

MidAmerican Energy has 4,295 megawatts of wind power overall, including the largest amount of utility-owned wind projects (3,317 MW).

CPS Energy of San Antonio, TX, has the largest amount of wind power serving its customers for a municipal utility (1,059 MW)
Basin Electric has the largest amount of wind power for its customers for a rural electric co-operative utility (716 MW)

Over 1,200 MW of wind capacity added in 2012 are owned by utilities, bringing utility ownership to 15% of all U.S. installed wind capacity.

The numbers for 2013 and 2014 aren't in yet, but a total of 13,131 megawatts of new wind projects were brought online in 2012, an annual growth rate of 28%, bringing total installed wind capacity in the U.S. to over 60 GW. Over 43% of the 3,250 electricity providers in the U.S. have wind energy on their system.



Reduced Environmental Risk: Wind power produces no carbon dioxide or air pollutant emissions, requires no water, mining, drilling or transportation of fuel, and generates no radioactive or other hazardous or polluting waste.

Price Hedge: Wind power lowers the portfolio volatility of electric utility power supplies, yielding benefits for future price risk and mitigating the impacts of fossil fuel price volatility.

Stable Pricing: Wind turbine prices have decreased to the lowest levels in nearly a decade, leading to falling total project installed costs as well.   Wind power in good wind resource areas is now very cost-competitive with any other new generating plant.

Good for the Bottom Line: Wind projects have very short construction periods and can be deployed quickly with positive impacts on generation planning and cash flows. In the case of wind ownership, additional rate base and tax-related benefits accrue to the utility as well.
