  1. PNM Energy Efficiency Business Rebates for Facility Managers Retrofit Rebate Opportunities July 13, 2010

  2. Agenda • Benefits of Investing in Energy Efficiency • Overview of the Business Energy Efficiency Program • How to get started • Trade Allies

  3. Why make the investment in Energy Efficiency? • Most cost effective energy “resource” • Proven and viable • Has multiple returns - financial and environmental • Effective method to manage energy cost risk • Utility Incentives

  4. Most cost effective energy “resource” $/ MWH

  5. Per Capita Electricity Sales

  6. Multiple ReturnsFinancial and Environmental • Annual GWh savings • Customers will save 5-7 times initial investment in energy bills over equipment lifetime • Reduced generation = CO2 reduction and water reduction (NM electric mix = 83% Coal)

  7. Commercial & Industrial Incentive Program Overview • Prescriptive measures • Lighting • Motors • HVAC • Refrigeration • Whole Building Approach (NC) • Custom Measures • Quick Saver Small Business (Facility) Program

  8. Incentives: Retrofit Projects Prescriptive Incentives are offered on per-unit basis for common predetermined energy saving technologies: Lighting & Lighting Controls HVAC Refrigeration Motors VSDs on HVAC fans & pumps

  9. Lighting Efficiency (Efficacy)

  10. Lighting Equipment Data • MLPW = Mean Lumens Per Watt • BF = Ballast Factor • MLPW = no. of lamps x mean lumens x BF / input Watts

  11. Light Quality • Color Rendering Index (CRI)

  12. Lighting Quality cont’d 0-20 CRI 80-100 CRI 60-75 CRI

  13. Lighting Specifications
