IPL Iowa Agriculture Program Background• 1992 – Alliant Energy’s Iowa predecessor utilities’ energy
efficiency plans began– Electric energy savings accumulated since plan inception
(1992 – 2007) equals 1.169 billion kWh – That savings is sufficient to power
• 116,900 average homes for a year• At an average of 10,000 kWh per year
• 2003 – Alliant Energy’s Iowa Agriculture Program began– 2004 – IPL added Agriculture field reps– In the first 3 full years of the program with field reps (’05-’07),
IPL’s Agriculture Program• Saved over 12.8 million kWh of electricity• Avoided equivalent of 9,960 metric tons of CO2 emissions• Avoided equivalent of annual greenhouse gas emissions from
1,824 passenger vehicles
6
IPL Iowa Ag Program Features• Dedicated ag field representatives
• Free farm energy audits
• Ag-specific prescriptive rebates
• Low-interest financing
• Custom rebates
• Outreach, education and collaboration
• Comprehensive ag energy-efficiency analysis services (e.g, helping customers comply with gov’t loan/grant program application requirements)
• Implementation assistance– Referrals to qualified contractors– New equipment comparisons– Recommendations of higher efficiency equipment
7
Free Farm Energy Audit• Provided by IPL Ag reps
• Pinpoints energy waste on grain and livestock operations
• Identifies energy-efficient technologies that will reduce energy usage
• Makes energy-efficient equipment recommendations
• Informs customers of available agricultural rebate programs
8
Ag Prescriptive Rebates• Customers receive specific dollar amounts
for installing qualifying high-efficiency equipment
• Trade allies earn cash incentive spiffs on energy-efficient program equipment they sell to IPL customers
• Equipment includes:– Automatic milker takeoffs– Clothes washers– Circulating fans– Heat reclaimers– Lighting– Livestock waterers– Low-pressure irrigation– Milk precoolers– NEMA Premium®-efficiency motors– VSDs for dairy pumps– Tractor heater timers– Ventilation Systems– Water heaters

Low-Interest Financing• Available to IPL customers who own the property on which
the equipment will be installed
• For financing qualifying energy-efficient equipment using energy provided by IPL
• Can be used instead of other IPL programs; for example cannot both finance and receive rebates
• Loan terms (exceptions may apply)– $1,500 to $250,000– Zero to 60 months– APR zero to 6.9%
• Call IPL’s Business Resource Center to confirm equipment qualifies: 1.866.ALLIANT (1.866.255.4268)
11
Custom Rebates• For projects that don’t qualify for the
prescriptive rebate program due to– Size– Scope or – Unique characteristics of the energy-
efficient equipment
• Customers receive 150% of annual incremental energy dollar savings for installing qualifying high-efficiency equipment
12
Outreach• Exhibitor
– ACEEE (American Council for an Energy Efficient Economy)– Celebration of Agriculture (sponsor)– Farm Progress Show– Iowa Farm Bureau Federation Annual Meeting– Iowa Pork Congress– Iowa State Fair– Hay Expo– MEEA (Midwest Energy Efficiency Alliance) – WMT Ag Expo– World Dairy Expo– World Pork Expo
• Ag reps in the field (customer, dealer, manufacturer visits, etc.)• Direct marketing and advertising
13
Education• Ag reps / product manager presentations at meetings
hosted by– Banks– Community colleges– Economic development (e.g., IDED)– Iowa Farm Bureau Federation– ISU extension
• Education topics– General energy-efficiency on the farm, in agri-business– Saving money with IPL’s energy-efficiency programs– Safety– Stray voltage
14
Collaboration• Builders
• Fan manufacturers
• Trade Ally network (dealers who sell qualifying energy-efficient equipment)
• IOUs, other utilities
• Iowa Farm Bureau Federation
• Office of Consumer Advocate
• USDA Rural Development
• Iowa State University– Ventilation– Anaerobic Digesters
• University of Illinois– Bess Labs – ventilation
• University of Minnesota– Natural air drying
15
Comprehensive Agriculture Energy–Efficiency Analysis Services• USDA 9006/9007 REAP audits performed by IPL ag reps
• To date, 400+ energy audits in support of USDA REAP Grants

IPL’s IA Survey of Participating Farmers:Main Barriers to Future EE Projects
2006 survey – participant sample = 53
No funds available, 44%
Need more information,
13%
No major obstacles, 10%
Energy savings don't justify cost, 14%
Other reasons, 16%
Don't know, 3%
17
Site/Operation Specific
• Accurate baseline energy information– Every operation is different
• Accurate prediction of actual energy savings– Can’t predict more savings than used
• Accurate implementation costs
• Accurate operational/replacement costs– Lifecycle costs– Management requirements– What’s plan “B” (i.e. VFD’s on critical operations)
18
Site/Operation Specific cont.
• Provide information in the appropriate format– REAP Energy Audit has specific format and information
requirements– Bankers may have specific information requirements
• Incentives– Cash incentives– Financing– Grants
• Talk to your utility early in the process– May need infrastructure upgrades– Revenue justification– Proper rate application (i.e. interruptible, demand etc)

REAP Energy Audit1. Situation report
Provide a narrative description of the facility or process, its energy system(s) and usage, and activity profile
2. Potential improvementsList specific information on all potential energy-saving opportunities and their costs
3. Technical analysis Estimate the annual energy and energy costs savings expected from each improvement identified in the potential project
4. Potential improvement description A narrative summary of the potential improvement and its ability to provide needed benefits, including a discussion of non-energy benefits such as project reliability and durability
