5 Energy and Water Savings from Optimal Irrigation Management and Precision Application Lori Rhodig, Northwest Energy Efficiency Alliance (NEEA) Dr. Charles Hillyer, Oregon State University (OSU)

6 NEEA’s Role  Fill the energy efficiency pipeline  Accelerate market adoption  Leverage the power of the region

7 Impact of Ag Irrigation in the Region ~ 5% or $335M Based on 2007 usage – data from NW Power Conservation Council’s Sixth Power Plan

8 Initiative Goal, Objectives and Deliverables Created by NW growers, utilities and NEEA in partnership with key global suppliers KEY DELIVERABLES THE GOAL Economic enhancement through 20% Agricultural Irrigation energy efficiency by % by 2020 DELIVERABLES  Improve yield uniformity  Improve energy intensity  Water goes further  More profit per acre  Decrease energy consumption OBJECTIVES Water and energy savings Irrigation technology + practices Industry- wide data standards
