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

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

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

Most cost effective energy “resource” $/ MWH

Per Capita Electricity Sales

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)

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

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
