3 1. Background and Site Information The Sample farm is located near Somewhere, Idaho. The farm operation consists of about 1,325 acres of irrigated farm ground with crop rotations of potatoes and small grains. Typically, 35% of the farm is planted in potatoes and 65% is planted in grain. The irrigation system consists of nine full circle center pivots with a design flow rate of 900 gpm, two part circle center pivots with a design flow rate of 550 gpm, and hand lines on some of the pivot corners. There are three irrigation pump stations that irrigate the entire farm, the Main Well and Booster, the West Well and Booster, and the Barn Well. There are also three potato storage units with fan ventilation systems, the A Frame Cellar, the Behlen Cellar, and the New Behlen Cellar. Rocky Mountain Power is the electricity provider for all of the irrigation systems and potato storage units on this farm. Mr. Farmer is interested in reviewing the existing equipment and operation and identifying any potential energy savings opportunities that may exist. The baseline description and potential energy saving opportunities for each irrigation pump and potato storage unit are summarized in Section 3 below. 2. Summary of Recommendations Table 1 below includes a summary of the recommended energy saving measures for this farm. Only those measures with a simple project payback of 10 years or less are included in the table. Table 1.

The well VFD will be set to maintain 10 psi at the pump and the booster VFD will be set to maintain 85 psi at the pump. The total estimated energy savings for installing VFDs on the 600 hp deep well and the 200 hp turbine booster pumps are 117,846 kwh/yr. The current cost of energy for this system is $0.0501/kWh and $5.42/kW resulting in approximately a $5,903 cost savings/yr for this project. The total estimated project cost for both VFDs is about $105,000 based on similar projects. The simple project payback for this project is estimated to be 17.8 years. There may also be incentives available through Rocky Mountain Power for this project that would decrease the overall project cost and the project payback. The calculation spreadsheet is included in the Appendix West Well & Booster Pump System The West Well pump is a 500 hp deep well turbine pump and the West Well Booster is a 200 hp turbine booster. Both of the pumps have electric motors. The well pump is a Verti-Line pump with 8 stages of 14RM bowls and 1 stage of a 14RL bowl, all at full trim.

(%) Operating Hours Rebuilt Pump ,854 Key Assumptions/Notes The existing pump motor efficiency was assumed to be 92%. The pump efficiency for the rebuilt pump will be at least 83%. The rebuilt pump efficiency was taken from the pump curve and reduced by 3% for the analysis. The total estimated energy savings for rebuilding the 350 hp well pump are 43,193 kwh/yr and 23 kw/month. The current cost of energy for this system is $0.0501/kWh and $5.42/kW resulting in approximately a $2,815 cost savings/yr for this project. The total estimated project cost for rebuilding the pump is about $17,000 based on similar projects. The simple project payback for this project is estimated to be 6.0 years. There may also be incentives available through Rocky Mountain Power for this project that would decrease the overall project cost and the project payback. The calculation spreadsheet is included in the Appendix A Frame Potato Cellar The A Frame Potato Cellar has the capacity to hold 85,000 hundred weight sacks of potatoes. This cellar has a 20 hp fan with an electric motor that provides ventilation and cooling to the potatoes. The potato cellar is usually filled around the 1 st of October and emptied around the 1 st of July on average. After the potato cellar is filled it takes about 45 days on average to cool the potatoes to the desired storage temperature. During cool down the fan operates at full speed whenever outside air temperatures are low enough to provide cooling to the potatoes. It is estimated that the fan runs an average of 24 hours per day during cool down. After cool down, the fan typically operates 12 hours per day at full speed to maintain storage temperatures.

The total estimated energy savings by installing a VFD on the A Frame fan are 3,900 kwh/yr. The current cost of energy for this system is $0.0419/kWh and $12.35/kW resulting in a cost savings of about $163/yr for this project. The total estimated project cost for the VFD and associated equipment is $10,000 based on similar projects. The simple project payback for installing VFD on the fan would be about 61.3 years. The energy savings potential with a VFD is limited on this potato cellar due to the limited airflow capacity of the system. It is not recommended that a VFD be installed on this fan. The calculation spreadsheet is included in the Appendix Behlen Potato Cellar The Behlen Potato Cellar has the capacity to hold 95,000 hundred weight sacks of potatoes. The Behlen Cellar has two 10 hp fans with electric motors that provide ventilation and cooling to the potatoes. The potato cellar is usually filled around the 1 st of October and emptied around the 1 st of August on average. After the potato cellar is filled it takes about 45 days on average to cool the potatoes to the desired storage temperature. During cool down the fans operate at full speed whenever outside air temperatures are low enough to provide cooling to the potatoes. It is estimated that the fans run about 24 hours per day on average during cool down. After cool down, the fans typically operate 12 hours per day at full speed to maintain storage temperatures.

The current cost of energy for this system is $0.0419/kWh and $12.35/kW resulting in a cost savings of about $606/yr for this project. The total estimated project cost for the VFDs and associated equipment is $12,000 based on similar projects. The simple project payback for installing VFDs on the fans would be about 19.8 years. It is recommended that an actual project cost estimate be obtained and compared to the expected energy savings before an implementation decision is made. The calculation spreadsheet is included in the Appendix New Behlen Potato Cellar The New Behlen Potato Cellar has the capacity to hold 50,000 hundred weight sacks of potatoes. This cellar has a 15 hp fan with an electric motor that provides ventilation and cooling to the potatoes. There is an existing VFD controller on the fan motor that allows the fan to operate at reduced speeds to maintain potato temperatures during the storage period. The potato cellar is usually filled around the 1 st of October and emptied around the 1 st of May on average.
