Cutting Fat on the Farm Saving money with efficiencyRichard Stroh, Bonneville Power Administration Harvesting Clean Energy Conference Boise, ID October 24, 2011
BPA Agricultural Program Offerings • Irrigation • Farms and Ranches • Greenhouses • Turf • Livestock Confinement • Utility Transformers
Irrigation Efficiency Programs • Pump Testing (Irrigation System Analysis) • Scientific Irrigation Scheduling • Variable Speed Drives for Turbine Pumps • Hardware Rebates and System Upgrades • Rebates for Green Motor Rewinds • Rebates for Premium Efficient Motors
What is a Pump Test • A measurement of the flow, pressure and lift produced by the pump and input power of the motor. • Efficiency = x 100 Power output Power input

Utility Financial Assistance (Example 1) After Intake: 6” Steel Pipeline Discharge: 6” Steel Pipeline Flow: 485 gpm Discharge Pressure: 59.0 psi Delivery Pressure: 59.0 psi Power: 30.3 hp Before Intake: 4” Flex hose Discharge: 4” Portable Aluminum Mainline Flow: 399 gpm Discharge Pressure: 78.1 psi Delivery Pressure: 58.5 psi Power: 31.1 hp
Added Wheel Line to System Annual Savings: 7,745 kWh Incentive: $1,936 Project Cost: $4,754 33% Savings
Utility Financial Assistance (Example 2) After New Water Source: 200 hp and 150 hp canal pumps and mainline to connect to existing system. Annual Savings:493,637 kWh Incentive: $145,352 Project Cost: $396,058 Before Original Water Source: 125 hp and 400 hp deep well pumps – 400 ft lift.
Scientific Irrigation Scheduling Applies to systems with greater capacity than what is needed to meet normal crop needs.
Scientific Irrigation Scheduling • Fixed deemed incentive per acre • Requires weekly data and soil moisture measurement • Crop type, acreage, energy savings and scheduling costs must be submitted to BPA at the end of each irrigation season
Livestock Confinement Operations • Dairies • Hog Farms • Cattle Feedlots ▼ Links Email & IM Direct link HTML code IMG code ▶ Photo info ▾ Loading...
Transformer De-energization • Incentive to electric utilities that currently do not disconnect irrigation pump transformers during the off-season.
Measures • HVAC System Controls • Heat pumps and solar water heating • Heat exchangers • Lighting • VFD’s for vacuum pumps • Freeze resistant watering tanks
On the Horizon • Update VFD offering • Turf smart controllers (municipal parks, cemeteries, golf courses, residential and commercial) • Irrigation system upgrades for nurseries and greenhouses • LEPA (Low Energy Precision Application)
Variable Frequency Drives (VFD) • Ending two year pilot project ($/hp) • Turbine pumps only • Program will be updated April 2012
Turf Smart Controllers • Finishing up final year of pilot • Will evaluate the data to determine measure possibility, hopefully available in April • Multi-sector measure: Small Ag farms, Residential/commercial landscaping and lawns, governmental/utility
Irrigation System Upgrades - Nurseries/Greenhouses • Considering investigating the need for system upgrades for nurseries and greenhouses similar to pivots, wheel and hand line systems
LEPA • Will be evaluating various demonstration sites to determine effectiveness on different soil/climate/crop conditions • Has the potential to save considerable water and energy on the right crop • LEPA uses very low pressures (6 - 10 psi at the nozzle). This, along with the fact that less water per acre needs to be pumped, can lead to substantial energy savings. • Could be the next generation of sprinkler upgrades
