    • … to solve the new energy eqution. We face a new energy equation with many variables. Increasing demand for energy is a key driver of rising energy prices. As a result, there is a renewed focus on renewable energy and energy efficiency — “save-a-watts” vs. megawatts. There is mounting concern about global climate change and further reducing air emissions. And, we must continue to grow earnings and dividends. These variables present both challenges and opportunities. We believe we can solve this new equation with our sustainability focus. This means working to balance the needs of all of our stakeholders. These efforts will keep our prices affordable and our service reliable as we continue to work to reduce our environmental footprint and earn superior returns. This delicate balancing act requires us to challenge conventional wisdom with new thinking and innovation. It means changing our own minds and habits and those of our stakeholders. We must still generate megawatts, but we believe we can produce significant save-a-watts as well. In 2006, we repositioned Duke Energy to do just that.

    • chaIrman’s letter to stakeholders dear fellow investors, customers, employees and all who have a vested interest in our success — our partners, suppliers, policymakers, regulators and communities: I want to thank the entire Duke Energy team for accomplishing both a merger and a spinoff last year. Never before in my career have I seen people work so hard to resolve so many complex issues. Our many financial, operational and policy accomplishments in 2006 were the result of your dedication and support. For our other stakeholders, let me summarize our key accomplishments simply by saying that we did what we said we would do in our 2006 Charter. 2006 ongoing diluted earnings per share of $1.81 exceeded 2005 ongoing diluted earnings per share of $1.73. Duke Energy’s total shareholder return for 2006, before the spinoff of Spectra Energy in early 2007, was 26.3 percent. We outperformed both the Philadelphia Stock Exchange Utility Sector Index (20 percent) and the S&P 500 Index (15.8 percent). The strategic steps we took last year positioned the company for growth in 2007 and beyond. We established an industry-leading electric power platform through the successful execution of the merger with Cinergy — and we did it in 11 months. (left) James e.

    • Defining the new energy eqution For more than a century, we have supplied our customers with affordable and reliable electricity. Our product is considered an essential service. It has also made possible many innovative technologies that enhance our customers’ standard of living. And it has helped keep our local and state economies competitive in the global marketplace. Providing adequate power was once as simple as balancing supply and demand. Although that is still the core of what we do, times have changed. Today, we face the unprecedented challenge of solving a new energy equation. During a time of rising and volatile fuel prices, historic environmental challenges and industry restructuring, the demand for electricity continues to grow. With our commitment to sustainability, we must balance the growing demand for power with the investments needed to supply it — while reducing our environmental impact and keeping prices affordable. This requires new thinking on both the policy and technology fronts. 15 Duke energy 2006 summary annual report

    • solving the new energy eqution It is clear that we need to invest in enhanced reliability and in the expansion of our capacity to generate electricity to meet growing customer demand. We know that investments in new state-of-the-art generation, renewables and energy efficiency can be made reasonably with appropriate and timely cost recovery. Historically, regulators have rewarded utilities for selling more of their product, not less. To solve the new energy equation, we need to change minds about the types of investments that should be eligible for recovery through rates. We are especially interested in building public support for investments in energy efficiency — the “fifth fuel,” which lowers overall customer demand and reduces or eliminates greenhouse gases and other emissions. 21 Duke energy 2006 summary annual report

    • advncing the “fifth fuel” — u.s. epa cse study As Sam Pagán of the U.S. Environmental Protection Agency (EPA) notes on a previous page, when the agency needed an energy management and monitoring system for its massive complex of labs, offices and computing facilities in Research Triangle Park in North Carolina, Duke Energy delivered. Three teams from Duke Energy — account management, business development and custom delivery — collaborated with the EPA’s energy management team to get the job done. The first idea was to measure the allocation of electric power and its costs building by building. But it soon became apparent that to achieve the EPA’s objective — to view total energy use in real time and analyze that data — a more comprehensive solution would be needed. The teams worked together to replace ineffective mea- surement and metering systems with a new energy monitoring and reporting system. The new system tracks the use of city water, natural gas, fuel oil, chilled and heated water, and electricity for the whole complex. It collects the data on a secure Web site and makes it available to campus energy management systems. Controllers working from a central office, or from anywhere on campus with a wireless laptop com- puter, can monitor and project the energy needs for individual buildings or for the entire complex. The Duke Energy team also earned the right to install and maintain the system, which may serve as a model for other EPA facilities. As part of the company’s renewed focus on energy efficiency, Duke Energy con- sults with its other large business customers on the benefits of total energy measurement systems. 25 DUKE ENERGy 2006 SUMMARy ANNUAL REPORT
    • Meeting steadily growing demand Plans to modernize our Cliffside Steam Station in North Carolina will ensure that our customers in the Carolinas have an affordable and reliable supply of power to support the region’s economic growth. Our plan called for replacing four old coal units with two supercritical and highly efficient 800-megawatt coal units using advanced emissions controls. In late February 2007, we received a notice of decision from the North Carolina Utilities Commission, which authorized building one of the two units. The commission also accepted our com- mitment to invest 1 percent of our revenues in the Carolinas for energy efficiency, subject to appropriate regulatory treatment, and our plan to retire older, less efficient units. Our estimates were based on two units, and as this annual report was being published, we still needed an air permit for this project. We are studying the commission’s decision and the project to determine how to proceed. We won’t make a decision until we have a clearer understanding of the overall costs as well as the conditions of the air permit. We are also evaluating the possibility of enhancing and accelerating natural gas-fired plants in our portfolio. Another important element of our generation strategy is the 2,234- megawatt William States Lee nuclear plant we are proposing to build in South Carolina’s Cherokee County. We also continue to explore building an advanced cleaner coal plant in Indiana, and we are pursuing additional energy efficiency programs and renewable technologies. The net result of these initiatives will help us meet steadily increasing customer demand while reducing multiple environ- mental impacts of our operations, including carbon emissions.

    • Chllenging conventionl wisdom Our customers want us to solve the new energy equation, and our track record gives them confidence that we can do it. They want better information about their own energy use and more options to control it. For Duke Energy, that means not only providing our customers with electricity, but also showing them how to personalize their energy use. That’s our commitment. We will start by digitizing our electric distribution and transmission grids. These huge networks already link meters, transformers, substations and other technologies with a communication and control infrastructure. By taking our mostly analog distribution grid and converting it to a digital network, we can create an information-rich communication system. Our plan is to create the “utility of the future.” 27 Duke energy 2006 summary annual report

In essence, the meter becomes n for our customers.
