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

7 Multiple Returns Financial and Environmental Annual GWh savings Customers will save 5-7 times initial investment in energy bills over equipment lifetime Reduced generation = CO 2 reduction and water reduction (NM electric mix = 83% Coal)

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

9 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

10 Lighting Efficiency (Efficacy)

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