1 Cultivating Energy Efficiency in the Ag Community A Look at How Local Cooperatives Approach Agricultural Energy Efficiency ACEEE s Forum on Energy Efficiency in Agriculture Madison, Wisconsin Paul Gillis, CEM GEN~SYS Energy

2 GEN~SYS Energy Dairyland Power Cooperative 25 Member Cooperatives 16 Municipal systems 1,144 MW generation Corn Belt Power Cooperative 10 Member Cooperatives 1 Municipal Cooperative 295 MW generation

3 Digging In Dairyland s 3-Pronged Approach Energy Efficiency Programs Load Management Renewable Energy

4 Ag Energy Efficiency Rules Target energy saving improvements for the equipment that is used the most or- when replacing failed equipment Turning equipment OFF saves the most energy If equipment is never ON, it doesn t need to be real efficient You can t save more energy than you consume Efficiency will be sacrificed for productivity No two farms are the same

5 Dairyland Incentive Programs Incentives based on Dairyland s avoided costs Offerings weighted towards Residential Sector Distribution cooperatives use Dairyland incentives to bolster their local programs Benefit the program participant, as well as the membership as a whole Can be coupled with state and federal programs

6 Dairyland 2010 Incentives Electric, heat pump, and solar water heaters Air conditioners, air source & geo heat pumps Energy Star appliances & appliance recycling Compact fluorescent lamps Fluorescent & HID lighting Incentives for Agriculture and C&I Custom incentives And more

7 Water heaters Heat recovery Seed Money Agricultural Incentives Pre-coolers/plate coolers Motors and drives Refrigeration Lighting Ventilation Livestock waterers

8 Dairy Automation - Energy Intensity Decreased kwh/cwt milk 3X milking More throughput Longer equipment runtime Natural ventilation Gravity flow waste handling Cow comfort/productivity is reversing the trend? Direct load out Robotic milking - labor savings Long daylighting Ventilation rates Waste handling Larger pumps Composters and digesters value added

9 Add Some Water Ag Water Heaters Incentives based on storage capacity/recovery time High energy factor electric units Tied to load management programs Many Co-ops offer: Free repair service Monthly credits on the power bill Reduced off-peak rates

10 Motors and Drives Long run hours Replace vs. rewind Size motors to loads VFDs big savings 3-Phase Motor Efficiency % Eff. Premium EPACT Standard Output Horsepower VFD + Vacuum Pump = Good Fit

11 Milk Cooling - Largest End-use and Savings Potential 40% 10% 15% 50%

12 Milk Cooling Largest End-use 40% + 10% + 15% + 50% = 115% Savings Holy Cow! Savings don t always add up

13 Ag Lighting CFLs - swine and poultry T5 and T8 fluorescent HID options LEDs - greenhouses Design assistance

14 Ag Ventilation Certified Efficiencies - AMCA/BESS Exhaust Fans - CFM per Watt Circulation Fans Lbs. of Thrust per Watt Up to 30% savings Bigger is better? Cleaning, adjustment, maintenance

15 You Can Lead a Horse to Water Livestock waterers Up to 100% savings Freeze up concerns Engine block heater timers Up to 80% savings Not for standby generators Load management Floor heat School buses/golf carts

16 Custom Incentive Examples Ag production and processing Compressed air upgrades Cold storage Low pressure irrigation HP reduction Grain drying and lumber drying Environmental controls Other applications request evaluation

17 Ag and C&I Audits Additional Ag Offerings USDA - REAP Program Awarded $100,000 grant Energy efficiency audits Renewable site assessments Research & demonstration Expansion plans Farm wiring & safety

18 Level I and II Farm Audits Estimated Electrical End-Uses Typical Wisconsin Dairy Farm ABC Dairy 19% 18% 13% 20% 1% 2% 15% 17% 9% 25% 11% 25% 6% 18% Lighting Waste Water Heating Feeding and Well Ventilation Other Vacuum/Recvr. Milk Cooling

19 Consumption & Demand Verification Example: Large Dairy Farm 120, ,000 80,000 60,000 40,000 Jan-04 Apr-04 Jul-04 Oct-04 Jan-05 Apr-05 Jul-05 Oct-05 Jan-06 20,000 0 Apr-06 Jul-06 Oct-06 Jan-07 Apr-07 Jul-07 Oct-07 Jan-08 Apr-08 Month Energy (kwh) Demand (kw) kwh kw

20 Additional Ag Offerings LP Gas service - BTU neutral Standby generator sizing, selection, & procurement Thermal imaging Power quality investigations Energy Voodoo Get rid of the weeds

21 On-line Energy Information Questline Services Midwest Rural Energy Council

22 Load Management - Agricultural Loads Dairy water heaters Electric space heat Grain and lumber dryers Irrigation systems Saw mills & feed mills Voluntary load shed Standby generators
