11 10 Xcel Energy - Overview Public Service Company of Colorado Southwestern Public Service Company Northern States Power Company Minnesota Northern States Power Company Wisconsin Gas Customers 2.0 M Electric Customers 3.5 M Vertically Integrated, Investor-Owned Utility Operates in 8 states No. 1 Utility Wind Energy Provider Total capacity of over 18,000 MW 19,500 miles of transmission 1,200 substations

12 Xcel Energy Existing Wireless Communications Microwave Cell 3G / 4G LTE Proprietary 900MHz mesh 3.65 GHz Wi-MAX Satellite 1-way paging 11

13 Xcel Energy Use of Cellular Have used cell for many years across the business From 1x to 2G and 3G to now, 4G LTE Many, many applications SCADA Remote monitoring Remote access (management) Fleet 12

14 Distribution Applications for LTE Capacitor Controls Remote Fault Indicators Recloser and Switch Controls Power Sensors Meters Remote Management of Devices Distributed Generation Telemetry 13

15 Benefits of Deploying a Cellular Solution Very fast to deploy new devices Relatively fast and easy to set-up initial network Low cost Modems are inexpensive and have many form factors Recurring monthly fees can be quite low and are getting lower Enables remote access to devices in hard to reach locations Network is highly reliable, fast and flexible 14

16 Network Design Generally leveraging business to business VPN s with cell carriers. Semi-private networks with Private IP s No Quality of Service (QoS) End device can be connected Serial or Ethernet Predominately TCP/IP 15

17 A New Use Case Minnesota Community Solar Program Distributed Solar Generation Multiple meters at each site Mostly rural sites Need for high-speed, low latency connectivity Need for secure network to pass SCADA traffic Need for QoS if possible 16

18 Enter a Solution DMNR and a Private Network Dynamic Mobile Network Routing - Enabled through Verizon Private, non-internet connected network Grants QoS on the wireless network Allows for BGP-like routing (Border Gateway Protocol) on a wireless network 17

19 Enter a Solution DMNR and a Private Network Dynamic Mobile Network Routing - Enabled through Verizon Private, non-internet connected network Grants QoS on the wireless network Allows for BGP-like routing (Border Gateway Protocol) on a wireless network LAN 1 Router 1 Wide Area Network Router 2 LAN 2 18

20 Functionality and Success Network design via DMNR and BGP allows for entire LAN to be broadcast across network to back-end routers Simplifies network design, configuration and maintenance Fast to deploy new devices connected and broadcasted in seconds Built in redundancy 19

21 Our Wireless Future Field Area Network (FAN) 1. Leverage Xcel Energy-Owned Backbone where possible 2. Leverage Xcel Energy-Owned property, towers, and building assets for radio coverage where possible 3. Design to capitalize equipment where Xcel Energy has full control of use, operations, and maintenance of the facility and equipment 4. Unify equipment and service across the Operating Companies 5. Follow and embrace industry standards for all tiers of network Deploy equipment that interoperates with other 3 rd party equipment 6. Carefully integrate network monitoring systems 20

22 FAN Technology Comparison WiMAX Point to Multipoint Mobile Broadband Standard Point-to-Multipoint Operates at 3.65 GHz Higher Bandwidth (>1.5Mbps) Lower Latency (<100ms) Line of Sight Best used for low-latency or high bandwidth applications Wi-SUN Mesh Emerging Smart Utility Standard Multipoint-to-Multipoint Operates at 900MHz Lower Bandwidth (<300kbps) Higher Latency (>1s) Omni Directional Best used for reporting-only or latency-tolerant applications 21
