1 Evolving Grid 700 MHz Field Area Network (FAN) Case Study April 2018

2 Communication System Overview 877 Managed IP Devices 899 Miles of microwave links (29 link total) 21 are 2 x 180 Mbps microwave links 850 Miles of fiber optic links(primarily 1 GbE) 136 backbone nodes 116 nodes via layer 2 leased 1 Mbps Ethernet 8 DWDM nodes 880 cellular devices 28 dispatch radio base stations 90% territory Over 1000 vehicles Secondary Routed Networks 134 Craft Routers 32 RoIP Routers 23 Security Routers 850 MPLS services Monitored Comm System ~80,000 points ~4,000,000 alarm events per year ~60,000,000 point data values per year

3 Defining The Need Red New Black - Existing Blue To Be Upgraded / Expanded DG Recloser Automation Paperless Dispatch DA / FLISR Future EV s System Modeling Volt/Var Optimization (VVO) Demand Response Substation Automation Enabled Applications GIS OMS SCADA / EMS Device Controls Communications Network Field Sensors IT Infrastructure Distribution Protection AMI Operations Network Foundational Systems and Elements Circuit Topology

4 Defining The Need (cont.) Old System (ACC) 78 Stations 367 Feeders Problems 1-way Communications ACC software and hardware No direct voltage control Manual Data Collection Why: No Feedback, Impacts, Controller Risk Ineffective, Unsustainable 2-way power; Power Quality Data Lag, Inefficient 78% Customers LTC Load Tap Changer 1200 Capacitors Capacitor Voltage Regulator BootsNet Automated Capacitor Control (ACC): Custom in-house built in 1996

5 Defining The Need (cont.) 3 rd Party Perspective Technology: IVVC is in growth stage right on the cusp of maturity. IPC is NOT pushing the boundaries for implementation of a 3 Rd party IVVC solution and in fact are slightly lagging peer utilities in implementation of a centralized volt/var monitoring, control, and optimization system.

6 Defining The Need (cont.) Utility Comparison NV Energy Cellular Pilot Implemented Northwestern Energy 700 MHz Pilot Pilot Portland General 700 MHz Pilot Avista Cellular Implemented Underway Underway Idaho Power Proposed IVVC Platform Proposed Field Area Network Volt/VAr Control (IVVC) Distribution Management System Fault Locating/Restoration

7 Defining The Need (cont.) New System (IVVC) 78 Stations 367 Feeders 21-way Way Communications with Device Status ACC Coordinated software voltage and hardware and reactive control Monitor No direct and voltage control control with 2-way power flow Centralized Not designed Management, to handle 2-way Control, power & Analysis Near Manual real Data time Collection data minimize BootsNet 78% Customers LTC Load Tap Changer 1200 Capacitors Capacitor IVVC Automated Capacitor Control (ACC): Custom in-house built in Voltage Regulators BootsNet

8 FAN Design Decisions Licensed Radio 1) Foundation for flexible grid No Regret Decision Enables near term needs such as ACC replacement 2) Exclusive ownership and use Reserved frequencies and bandwidth Protected from interference 3) Capital Non-depreciating Asset 4) Finite Commodity; Resalable 5) Control future O&M costs 6) Strong cyber security IPC controlled vs 3 rd party carriers Analogous to purchasing Real Estate

9 FAN Design Decisions (cont.) Purchase Spectrum Upper 700 MHz A Block radio spectrum Licensed Geographically Cover entire IPC service territory

10 FAN Design Decisions (cont.) Alternatives Considered 1. Commercial Cellular High O&M Price change risk Technology change risk (2G, 3G, 4G ) Low priority outage response by cell carrier Security challenges 2. Unlicensed Spectrum Prone to interference Congested spectrum (late to the game) Security challenges 3. Existing IPC 2-way radio spectrum re-use (150 MHz) Very narrow bandwidth Interference Not suitable for DMS type applications; very limited data bandwidth 4. Hardwire (copper/fiber) Cost prohibitive

11 FAN Design Decisions (cont.) Expected Uses Dynamic Line Rating Volt/Var control system (ACC replacement) Fault Current Indicators Feeder Voltage Monitoring Recloser Protection, Monitoring Outage Detection (Sentry) Rate 19 Meters Demand side management programs Weather Stations River Flow Meters Replacing lease line scada (substations) AMI PLC Supplement
