Workshop February 4, 2016

Idaho Power Smart Grid Vision At Idaho Power, our smart grid vision remains focused on seven major characteristics : 1.Enhance customer participation and satisfaction 2.Accommodate distributed generation/storage 3.Enable new products/services/markets 4.Improve power quality 5.Optimize asset efficiency 6.Anticipate and respond to disturbances 7.Provide resilient operation/robustness 2

Idaho Power’s Smart Grid Strategy Focus investments in: Operations …real-time sensing, diagnostic, communications, and control equipment to increase efficiency and reliability of the system and make the system more resilient. Customer Systems …customer expectations are changing and they want more information about their energy use. Advanced Metering Infrastructure (AMI) …more fully utilize the information received from AMI meters to improve services offered. 3

Oregon Commission’s Smart Grid Goals The Commission’s goal is to benefit ratepayers of Oregon investor- owned utilities by fostering utility investments in real-time sensing, communication, control, and other smart-grid measures that are cost- effective to consumers and that achieve some of the following: –Enhance the reliability, safety, security, quality, and efficiency of the transmission and distribution network –Enhance the ability to save energy and reduce peak demand –Enhance customer service and lower cost of utility operations –Enhance the ability to develop renewable resources and distributed generation 4
