Xcel Energy MN Conservation Programs

History (Since 1990)

Number of Rebates given: Over 35,000

Total Rebate Dollars: Over $160,000,000

Largest Rebate: $1,450,000

6

What Customers Accomplished in 2014…

More then 481 Million kWh Saved, and nearly 850,000 Dth of Natural Gas Saved

That’s enough energy to power over 70,000 Twin Cities homes for a year

7

Economic Impacts Lower energy bills Lower Rate, Power plant are expensive to build Lower operating and maintenance costs Increased efficiency of operation Lower energy-efficiency project costs

Faster paybacks Lower up-front costs Higher return on investment Increased lifetime savings

8

Environmental Impacts Reduce emissions

1.054 lbs CO2 / kWh (1.161 lbs CO2/kwh - 2012) 11.7 lbs CO2/thermSince 2005, we have reduced CO2 emissions by

over 12%, SO2 emissions by 40% Pollution prevention

Avoid new power plantsMore than 3,000 Megawatts of power saved 11 mid-sized power plants

Green Energy

Where we are Today…Top 5 States for Wind Energy Production

TX (10,648 MW), IA (4,419 MW), CA (4,287 MW), IL (2,852 MW) and MN (2,718 MW)

Xcel Energy Rated #1 Utility Wind Provider –American Wind Energy Association (AWEA) – 11 Years in a Row!

We are also the #5 Ranked Solar Energy Provider

Xcel Energy’s Renewable Sources WindSource

Residential and Business Customer Program Allows the purchase of 100 kWh blocks of Wind

Energy (up to 100%) Other Renewable Sources

Hydro, Biomass, Solar As of 2013, 23% of Xcel Energy’s Electric Sales come from

Renewable sources (13% Wind, 7% Hydro, 3% Biomass) As of 2015 over 54% of the energy generated in MN is carbon

free. Morning of April 28th, 43% of the electricity on the grid came

from Wind Power – New Record!

Lighting Efficiency Prescriptive Rebates

Fixed incentives for installing energy efficient equipment Retrofit rebates for existing facilities of any size

One-to-one equipment change outs New construction rebates (new or major renovations)

Choose options that are more efficient than the standard

ENERGY STAR® Qualified Interior LED’s (Screw-in, Pin Based, Commercial Down Lights, etc.)

Lighting Controls – Occupancy, Motion or Photo Sensors Lighting Studies – For over lit or miss lit applications

15

Lighting – An Example

2 Parking Garages Convert 314 Fixtures (From MH and HPS to T8

Fluorescent Fixtures) Cost $46,000 Xcel Energy Rebate $26,690 Estimated energy savings $22,395/year (60%) Payback 0.9 years

16

Motor EfficiencyVariable Frequency Drives (VFD's)

Prescriptive VFD’s (on Pumps or Fans, Over 3,000 Hours)1 to 200 HP ($400 to $8,000)

Custom VFD’s (non Pump or Fan application, Less then 3,000 Hours, or Greater then 200 HP) Individually Determined ($400/KW saved)

Prescriptive Motor Retrofit Rebates1 to 200 HP ($200 to $13,500)

17

Compressed Air Study - A compressed air system assessment (> 10 hp)

Analysis of supply and demand, and airflow and /or electric metering

A written report that identifies leaks and waste, and associated energy costs

A list of system recommendations, paybacks, rebate opportunities and estimated energy savings

Study funding up to $25,000 depending on total operating compressor equipment (excludes back up)

Custom rebates (up to $400/kW saved) for study recommended improvements (preapproval required).

Prescriptive rebates Integrated VDS compressors 10 to 49 hp No loss drains

18

Compressed Air - LossLeaks and waste rob your production needs by at least 50%, and leaks are too expensive to ignore

19

Compressed Air Lifetime Cost

20

Custom Efficiency Program

Rebates for energy-saving projects not covered by our prescriptive equipment programs

Rebates are up to $400 per kW saved and $5 per MCF saved

Pre-approval is required prior to equipment purchase

21

Custom Efficiency - Examples

Refrigeration Equipment Non-ENERGY STAR® rated LED Retrofit, LED

Display signs Ventilation Controls, Demand Control Ventilation Free Cooling Air Compressor HP Reduction Motors > 500 HP, VFD’s > 200 HP, or VFD’s for Non

Fan or Pumping Applications

22

Studies

Evaluate energy usage Identify and qualify opportunities Build a business case for improvements

Taking the Next Step…Did you know, that on average, 30% of your

energy bill is wasted?

23

Types of Studies

Lighting Redesign Recommissioning Turn Key Services Fluid Systems Optimization Heating Systems Optimization

24

Energy Studies Analyze a major process or system to help decision-making on new

installations and energy efficiency improvements Xcel Energy will pay up to 75% of the study cost, not to exceed

$25,000 Preapproval is required for studies These are the types of studies:

Cooling system replacement Custom Efficiency Motors and Drives Refrigeration Space/process heating
