NextEra Energy, Inc. (hereafter, NEE) is one of the largest electric power companies in North America, with over 42,000 mw of generating capacity in 26 states in the U.S. and 4 provinces in Canada, and employing approximately 14,800 people as of December 31, 2012. NEE provides retail and wholesale electric services to nearly 5 million customers and owns generation, transmission and distribution facilities to support its services. It also purchases electric power for resale to its customers and provides risk management services related to power and gas consumption for a limited number of customers. NEE is the largest generator in North America of renewable energy from the wind and sun. NEE owns and operates approximately 17% of the installed base of U.S. wind power production capacity and operates approximately 14% of the installed base of U.S. utility-scale solar power production capacity as of December 31, 2012. NEE also owns and operates one of the largest fleets of nuclear power stations in the U.S., with eight reactors at five sites located in four states, representing approximately 6% of U.S. nuclear power electric generating capacity as of December 31, 2012. NEE's business strategy has emphasized the development, acquisition and operation of renewables, nuclear and natural gas-fired generation facilities in response to long-term federal policy trends supportive of zero and low air emissions sources of power. NEE's generation fleet has significantly lower rates of emissions of CO2, SO2 and NOx than the average rates of the U.S. electric power industry with approximately 97% of its 2012 generation, measured by mwh produced, coming from renewables, nuclear and natural gas-fired facilities. Certain environmental attributes of NEE's electric generating facilities, such as renewable energy credits, emissions reductions, offsets, allowances and the avoided emission of GHG pollutants, have been or likely will be sold or transferred to third parties, who are solely entitled to the reporting rights and ownership of the environmental attributes.
