2 Who is Duke Energy? Largest power company in USA 28,000 employees 95,000 square miles of territory 350 Electric Generating Units 57,500 MW of generating capacity 32,200 miles of transmission lines 262,900 miles of distribution lines 7.2 million Customers NC 3.2 million FL 1.7 million IN 810,000 SC 730,000 OH/KY 840,000 2

3 Sustainable Energy $ 4 billion invested in solar and wind projects nationwide since 2007 $ 3 billion investment in renewable energy over the next 5 years 23 solar and 15 wind farms operating in 12 states (NC #3 nationally for solar) In 2015, DE Florida announced the addition of 500MW of utility-scale solar by ,800 MW of solar / wind capacity nationwide 6,425 MW of Hydroelectric capacity world wide 300 MW of Biomass capacity in NC & FL Total over 8,500 MW of zero-emission, renewable electrical generating sources 3

4 Why Offer Energy Efficiency Incentives? Question: Why does Duke Energy offer incentives to save energy? Answer: Since 1951, the Florida Public Service Commission (PSC) has maintained regulatory authority over investorowned electric utilities. As part of the PSC economic and regulatory goals, Duke Energy agrees to assist consumers in their energy efficiency improvements as part of their rate structure plan. 4
