  17. Partly Cloudy With a Chance of Rain Forest Scientific field research builds upon legacy of environmental stewardship at Duke Energy 8/5/2011 Six Duke Energy employees recently completed a week-long scientific expedition to the Rio Cachoeira Nature Reserve in Paraná, Brazil, to assist with research on the impact of climate change on the Atlantic Rain Forest. Two employees from the U.S. and four Duke Energy International employees from Latin America were selected to participate. This environmental education pilot project was sponsored by Duke Energy’s Energy and Environmental Policy department in partnership with the Earthwatch Institute, a non-profit conservation organization.

  18. Partly Cloudy With a Chance of Rain Forest Legacy of Environmental Stewardship The purpose of this pilot project is to provide Duke Energy with insight into the impacts of climate change globally and to understand how employee education and engagement on environmental issues can benefit the company. The environmental stewardship strategy mirrors Duke’s energy and environmental policy efforts, which are focused on securing certainty for our customers in a carbon-constrained future. “In a world where increasing environmental regulation is anticipated, we need to take a long-term view on the impact of climate on our business,” said John Stowell, vice president, Energy and Environmental Policy.  “Pilots such as the Brazilian expedition help employees experience firsthand how the issue is relevant to our company, our shareholders and our customers.” About the Expedition The Atlantic Rain Forest is one of the most endangered tropical forests in the world, offering a unique opportunity for study. The landscape includes new and old growth in low-level and elevated terrain. Scientists have long known that forests have tremendous potential to hold carbon in trees and soils. Duke Energy employees helped scientists better understand the pressures on forests by engaging in data collection and field research. “Since the time of colonization, the Atlantic Rain Forest had been deforested by 93 percent. Due to reforestation efforts, it has since risen to 11 percent of forested growth,” said Kris Knudsen, EHS environmental specialist, who took part in the research. “Each day we’d walk several kilometers to the laboratory or up into the forest. Experiments included taking measurements on hundreds of trees, analyzing when trees produce fruit, weighing bee hives to determine honey production, collecting leaves and flowers, and measuring and weighing dried vegetation that had previously been harvested. We also took the opportunity to plant new trees.” “This is the second time that Duke has participated in an Earthwatch expedition,” said Stowell. “In 2008, four employees ventured to Iceland, studying potential effects of climate change on glacier lands. Expeditions like the one in Brazil are one way for employees to engage directly in stewardship activities on the international level and form perspectives that they can then use to help Duke achieve sustainability at home.” The team not only contributed to the science of climate study; but formed closer working relationships with employees across our company.For additional information and photos of the work by the Brazilian team, view the slide presentation(PDF) (photos courtesy of Kris Knudsen).

  19. Energy Efficiency Plan • What is Duke Energy’s Energy Efficiency Plan? • Duke Energy is committed to finding new ways to help your business address rising energy costs with environmentally sound, low-cost options. Our Energy Efficiency Plan is a new regulatory approach to energy efficiency. The plan supports the development of energy efficiency conservation programs to help our customers save money and energy. By using less energy, we can help keep energy rates lower and reduce the need to build additional power plants. • Features & Benefits • Provides all customers with new Energy Efficiency programs, including energy assessments and incentive rebates, making access to energy-saving equipment easy and affordable. • Reduces electricity consumption, helping Duke Energy avoid building new generation facilities. • Represents an important departure from traditional energy efficiency regulatory models where utilities are compensated based on how much they spend rather than the results they produce. Under the plan, Duke Energy will only be paid for verified energy reductions.

  20. Energy Efficiency Plan • How It Works • Duke Energy will assist customers in “saving watts” rather than relying solely on building new power plants to meet energy demands. • Duke Energy will provide all customers with energy efficiency programs to help them conserve energy. • After four years, the energy efficiency programs are projected to displace the need for 1,700 megawatts (MW) of capacity, or about 745,000 megawatt hours. As the results from new energy efficiency programs are realized, the company will retire older coal plants, significantly reducing emissions. This MW reduction lessens the need for new power generation and helps keeps rates lower. • The cost associated with implementation of our Energy Efficiency Plan will be shared among all customers. Through active participation in these program offerings some large business customers could see up to a 15 percent reduction in their electric bills. • Some Duke Energy industrial customers and qualifying large commercial customers in can “opt out” of the program if they’ve developed their own energy efficiency programs or intend to do so in the near term.

  21. CONSERVATION AND DEMAND RESPONSE PROGRAMS Large Business Energy Assessments • Program offers three levels of Assessments: On-line, Off-Site, On-site Smart $aver Nonresidential Incentive Program - Prescriptive • Program offers defined incentives to nonresidential electric customers to help offsetincremental cost differences between standard and high-efficiency equipment Smart $aver Nonresidential Incentive Program - Custom • Program offers customers financial assistance for projects involving more complicated or alternative technologies, or those measures which are not covered by other prescriptive incentive offerings. Available to all assigned customers, not just schools PowerShare • Program offers customer incentives for providing capacity in emergency and economic constrained times

  22. DEVELOPING A SUSTAINABLE ENERGY PLAN • How can I improve my company’s energy efficiency? • Develop a sustainable energy plan (SEP) • A critical step for success • Make sure you understand the “who” and “what” of the plan • Who will champion the plan and make implementation decisions? • What financial criteria will be used to evaluate opportunities? • Attend our SEP workshops, offered twice annually in your state/region • Establish benchmarks and goals based on current performance • Benchmark metrics can be total energy or based on unit of production, square footage, per student or employee, etc. • Energy reduction goals – both short-term and long-term objectives

  23. SMART $AVER ENERGY ASSESSMENTS • Energy Assessments Offerings • On-line assessment – free • Available through the Business Services Newsline • Tools You Can Use • Benchmark data by business segment • C&I energy efficiency recommendations by end use and segment • Facility Assessment Wizard • The Facility Assessment Wizard provides recommendations tailored to your business or industry • Recommendations address lighting, HVAC, energy management systems, boilers, process heating and cooling, etc.

  24. SMART $AVER ENERGY ASSESSMENTS • Energy Assessment Offerings (cont.) • Off-site assessment – no charge for customers who have not opted out • An off-site assessment is a conference call with the customer to help you identify energy-consuming equipment and energy efficiency opportunities • The customer is provided a worksheet questionnaire for collecting facility information • A phone-based interview, typically one to two hours, is conducted with the customer by an assessor • At the conclusion of the interview, the customer, assessor and Duke Energy decide if an on-site assessment is warranted • If not, the assessor prepares a report and reviews the recommendations with the customer

  25. SMART $AVER ENERGY ASSESSMENTS • Energy Assessment Offerings (cont.) • On-Site Assessment – Available to customers who have not opted out – $3,000 for a one-day on-site analysis and report – $600 per additional day on-site • The on-site assessment follows the phone-based, off-site assessment. • Additional data is gathered, and measurements are taken during the on-site work • The assessor compiles the report and submits to Duke Energy for review • The report is presented to the customer for review, and a live meeting or face-to-face meeting is scheduled to step through the results • Customers can recover their portion of the costs dollar-for-dollar when they use Smart $aver incentives (i.e., for every dollar of incentive they are eligible for, they will receive two dollars up to the cost of the assessment). Note: • Customer costs are based on Duke Energy paying for approximately 50% of the total cost – varies but approximately $6,000 plus $1,200 per additional day.

  26. SMART $AVER ENERGY ASSESSMENTS • What is included in the On-Site assessment report? • The report includes an extensive executive summary of recommendations and supporting information, including: • Energy conservation measures – describes each opportunity • Implementation costs – estimates equipment and labor requirements • Annual energy savings – estimates project’s utility bill savings • Smart $aver incentives – Prescriptive and Custom Incentives • Financial metric – simple payback or internal rate of return • The report will also identify demand response opportunities and savings from participating in PowerShare® if applicable.

  27. SMART $AVER™ INCENTIVE PROGRAM • Offers incentives to Duke Energy nonresidential electric customers to help offset the incremental cost differences between standard and high-efficiency equipment • Incentives typically do not exceed 50% of the incremental cost difference • Helps move the market to more efficient equipment • Increased demand results in lower costs as retailers and distributors stock more energy efficient equipment • Two Programs: Prescriptive and Custom • Smart $aver Prescriptive includes incentives for standard high efficiency equipment (motors, pumps, HVAC, lighting, etc.) • Smart $aver Custom provides incentives for high efficiency equipment not addressed through the prescriptive program

  28.

SMART $AVER CUSTOM INCENTIVES • What are Custom Incentives and why do we offer them? • Smart $aver Custom Incentives offers incentives for energy efficiency measures not addressed by the Prescriptive Incentives • Proposed energy efficiency measures maybe eligible for a Custom Incentive if they reduce electrical demand (kW) and/or save electrical energy (kWh) • Custom Incentives are offered to ensure all cost-effective efficiency measures are addressed by our incentive program and give our customers more opporutnities to implement these measures

  30. SMART $AVER CUSTOM INCENTIVES • What are examples of Custom Incentive applications? • Nonprescriptive lighting measures such as reflectors • Thermal improvements to the building envelope: roof and wall insulations, upgrades to windows and doors, etc. • On-demand ventilation systems • Energy management systems • HVAC tune-up initiatives • Energy recovery systems • Energy-saving process upgrades • Retro-commissioning of existing buildings • Compressed Air Systems

  31. POWERSHARE® PowerShare® is Duke Energy’s brand name for commercial and industrial Demand Response programs. • What exactly is Demand Response? “Changes in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity over time, or to incentive payments designed to induce lower electricity use at times of high wholesale market prices or when system reliability is jeopardized.” Federal Energy Regulatory Commission Demand Response offers customers an incentive to curtail energy load during periods of high demand.

  32. Why do we offer Demand Response programs? • Can be counted towards Reserve Margin requirements. Reduces need to build plants or purchase capacity in the marketplace. • Example 1: • Projected System Load: 10,000 MW • Reserve Margin requirement: 15 % • Total Capacity Requirement: 11,500 MW • Less: Available Generation: 10,000 MW • Required Market Capacity Purchases: 1,500 MW • Example 2: • Projected System Load: 10,000 MW • Reserve Margin requirement: 15 % • Total Capacity Requirement: 11,500 MW • Less: Available Generation: 10,000 MW • Less: PowerShare: 100 MW • Required Market Capacity Purchases: 1,400 MW (Assuming market capacity price of $25/kW – savings to company from avoided capacity purchases = $2,500,000!)

  33. Why do we offer Demand Response programs? (cont.) • For the effect on system peak and improved reliability:

  34. What options are available? • PowerShare Voluntary • Hourly event prices are posted the day of an event • Customers have the right, but not the obligation to participate • There are no penalties for nonperformance • Customers get paid for results as long as they provide at least 50% of what they nominate • Can be combined with PowerShare Mandatory • PowerShare Mandatory • 30 minutes advance notice of event • 100 hours per year maximum interruption • 10 hours per day max • 10 interruptions per year max • Capacity Credit - $3.50/kW-month ($42/kW-yr) • Energy Credit - $0.10/kWh • Non-Compliance Penalty - $2/kWh • PowerShare Generator • 30 minutes advance notice of event • 100 hours per year maximum interruption • 10 hours per day max • 10 interruptions per year max • Capacity Credit - $3.50/kW-month ($42/kW-yr) • Energy Credit - $0.10/kWh • Non-Compliance Penalty - $2/kWh

  38. Benefit to Duke Energy • DETERMINATION OF ENERGY EFFICIENCY RIDER ADJUSTMENT • Energy Efficiency Adjustments (EEA) will be applied to the energy (kilowatt hours) billed of all rate schedules for each vintage as determined by the following formula: • SAW Non-residential Adjustment = Non-residential Avoided Cost Revenue Requirement + Non-residential Lost Revenues / Forecasted Non-residential kWh Sales (excluding opt out sales) for the Rider billing period • Where • Non-residential Avoided Cost Revenue Requirement = (Non-residential Demand Side Management Program Avoided Cost Revenue Requirement X 75%) + (Non-residential Energy Efficiency Program Avoided Cost Revenue Requirement X 55%) • Participation true-ups: After the first year, the Rider will include a true-up of previous Rider amounts billed to reflect actual customer participation in the programs. • Measurement and verification true-up: EM&V activities and results will be included in a mid-term EM&V-based true-up process that will be reflected in Vintage Year 3 Rider EE collections. A final EM&V true-up reflected in Vintage Year 6 Rider EE collections will incorporate all EM&V studies completed since the mid-term EM&V true-up. EM&V results will include measure-level savings adjustments and net-to-gross analysis. In addition, the mid-term and final true-ups will incorporate the most recent EM&V results in the avoided cost true-up, the lost revenue true-up, and the earnings cap true-up.

  39. Benefit to Duke Energy Shareholders • Earnings cap true-up: In the sixth year a true up will be billed, if applicable, to refund amounts collected through the Rider in excess of the earnings cap, in accordance with the following levels of achievement and allowed return on investment.
