3. Agenda • Overview of Energy Efficiency • Smart Ideas for Your Business • Types of Projects • Barriers / Benefits of Energy Efficiency • How to get started

4. Overview National Energy Efficiency Potential • McKinsey & Company Study-Unlocking Energy Efficiency in the U.S. Economy* • A $520 Billion investment in efficiency measures would yield $1.2 trillion in gross energy savings by 2020 • Lawrence Berkeley National Lab-U.S. Building-Sector Energy Efficiency Potential* • 1/3 of Business as usual electric consumption can be saved at a cost of $02.7/kWh • 2.5 year simple payback • Savings at 3.5 times larger than the investment required *McKinsey & Company. Unlocking Energy Efficiency in the U.S. Economy. July 2009 http://www.mckinsey.com/mgi/publications/Curbing_Global_Energy/executive_summary.asp *U.S Building Sector Energy Efficiency Potential.

6. Smart Ideas for Your Business

7. Smart Ideas What is the Smart Ideas Program? • Provides incentives for energy efficiency upgrades and equipment • Part of Illinois energy legislation passed in 2007 • Program implemented by ComEd, Ameren Illinois, and the Illinois Department of Commerce and Economic Opportunity • ComEd Goal: Reduce energy consumption by 1.2 million MWh (over 3 years) * Estimated based on planning projections

8. Funding for Energy Efficiency as a Percent of Utility Revenues Smart Ideas Source: American Council for an Energy-Efficient Economy, September 2007

9. Smart Ideas ComEd and DCEO manage different portions of the energy efficiency portfolio • Funding Split: 75% for ComEd programs and 25% for DCEO programs. • Sector Split: ComEd – Private Sector; DCEO- Public Sector and Low-Income. Business Solutions Public and Low-Income Solutions Residential Solutions ComEd DCEO

10. Smart Ideas Ineligible Measures Fuel switching Solar / Wind projects (other incentives available) Residential applications (other incentives available) Onsite Generation Peak Shifting What Does Smart Ideas Include? • Incentives • Prescriptive • Custom • Retro-commissioning (Low Cost / Operational) • Commercial Building • Compressed Air • New Construction • Retro-commissioning • Data Services • Energy Insights Online • ENERGYSTAR benchmarking

11. Smart Ideas Prescriptive and Custom Incentives • Incentives for popular prescriptive projects: • Exit signs $20 per sign • T5/T8 fixture with ballast 30¢ per watt reduced • Occupancy sensor lighting 9¢ per connected watt controlled • Motors $7 for 1 HP to $450 for 200 HP • Incentives for custom projects: 3-7¢ per kWh saved • Motors larger than 200 HP • VFDs on process motors • New compressed air systems, compressed air sequencing • Combine process chilled water systems • Free-cooling for process chilled water • Ground-loop heat pump for process cooling

12. Smart Ideas Think about Motors and Drives • Over half of the electric energy consumed in the US is used by electric motors. • Electric motors systems account for almost 70% of manufacturing sector electricity consumption. • A heavily-used motor may cost six to ten times its purchase price to operate per year. • NEMA Premium-efficiency motors operate at 1% to 4% higher efficiency than EPACT motors • NEMA Premium becomes the federal standard Dec. 19th, 2010

13. Smart Ideas Consider Retro-Commissioning for Compressed Air • Two system-size tracks • 500 HP and larger – traditional retro-commissioning • 100-499 HP • Rebate-based approach to study and implementation • Begins in June • Low- and no-cost measures – detailed analysis • Controls optimization • Scheduling • Sequencing • End-use analysis • Leak identification • Capital improvements – opportunity identification • Visit www.comed.com/bizincentives

14. Types of Projects

15. Types of Projects Who Is Implementing Energy Efficiency Projects?

16. Types of Projects Types of Energy Efficiency Projects

17. Types of Projects Armacell LLC • Combined two distinct process chilled water systems • Added heat exhanger • Reduced number of pumps • Added controls and VFDs • 1,596,269 kWh projected annual energy savings • $248,523 total project cost • $100,000 Smart Ideas incentive • Payback 1.7 years with incentive • Visit www.comed.com/bizincentives

18. Types of Projects Conrad Hotel • 311-guestroom luxury hotel • HVAC • Total project cost: $136,942 • Projected annual energy savings: 465,138 kWh • Incentives paid: $32,560 • Payback period without incentive: About 3 years • Payback period with incentive: 18 months

19. Types of Projects Chicago History Museum • Building size: 235,000 square feet • Measures implemented: Retro-commissioning • Incentives paid: $89,436 • Annual energy savings: 491,754 kWh • Annual energy cost savings: $40,200 • Total project cost: $11,400 • Payback period Less than 4 months

20. Barriers to Energy Efficiency

21. Barriers What Holds Customers Back • Availability of capital • Cost of capital • First cost • Credit and collateral issues • Payback/ROI requirements • Payback period of less than three years typical

22. Benefits of Energy Efficiency

23. Environment “Going Green” image boost Energy performance Stewardship Corporate sustainability initiatives LEED initiatives, both retrofit and new Benefits Energy Efficiency’s Triple Bottom Line People • Saving jobs • Creating jobs • Building environment Comfort • Space conditioning • Quality of work environment Dollars • Financial performance • Capital expenditures Savings • Process improvements • Deferred maintenance

24. Types of Projects Average ComEd Project • Changing 400 watt MH lighting to linear fluorescent (6LT8HO) • Changing 100 fixtures • Total project cost (ComEd project data) = $1.10 per watt reduced or $26,070 • Incentive = $7,110 • Energy Savings is $11,376 per year • Payback is 20 months with incentive (27.5 without)

25. Benefits Project Economics Over Time * Replace lamps Most people focus on the payback… …and ignore the potential long term savings! • Fixtures last over 10 years, while lamps need to be replaced after 5 years

26. Benefits A Look at the Numbers: (The red area) • Lighting system upgrade: $26,070 Less Smart Ideas incentive: ( 7,110) Net investment: $18,960 • Monthly electric bill: $10,000 Savings achieved by upgrade: ( 948) Net electricity bill with upgrade: $ 9,052 • Return on investment analysis: $948 x 20 months of savings: $18,960 $948 x 20 monthly payments: $18,960 Net costs over investment period: $ 0

27. Benefits How the Savings Continue (The green area) • At a measure life of five years*, the monthly utility bill savings that continue from month 21 to month 60 represent an additional $37,920 $948 savings x 40 months = $37,920 Assuming 4,800 hours/annually 4800/year x 5 years = 24000 hours (average life for a 4-ft T8 lamp) • A $18,960 investment made today pays for itself from savings in 20 months and yields an additional $37,920 in savings over the next 40 months. * Lamps would likely need replacing after five years

28. Benefits The Results • The customer gets a new lighting system with better performance and lower maintenance costs. • The $37,920 represents pure profit for the customer. • How many “widgets” would they have to sell to achieve $37,920 in profit? • Profit is realized from making the right decision about energy efficiency without having to make or sell any more product!

29. How to Get Started

30. Getting Started Where to Start • Engage an energy specialist that will visit your business, conduct an assessment and provide a complete proposal showing return on investment and savings potential • Contact your ComEd Account Manager • Contact your trade ally or consultant • Think about “high hours of use” processes that may mean additional, significant kilowatt reduction opportunities. • Are you tracking energy-savings opportunities or measures you already completed at your facility?
