3 1. Security – Robust end-to-end, aligned with NISTIR Deterministic – Smart Grid applications will share a logically isolated deterministic communications infrastructure. 3. Interoperable – Industry standard protocols will be utilized with a focus on migrating to IP/Ethernet consistent with industry direction 4. Privately Owned – Privately owned communications is preferred. Eliminate telecom circuits, O&M cost savings. 5. No Unanalyzed Single Points of Failure (Self Healing) – The communication architecture will be designed with no unanalyzed single points of failure. 6. Communications Maintenance Management & Monitoring – Inherent to the communications Architecture will be Communications Maintenance Management & Monitoring, i.e. the ability to maintain, monitor and control network devices. 7. Tiered Architecture – Unit/Distribution substations are linked to larger Transmission substations in a hierarchical design through new wireless technologies 8. Relay Protection Communications – Highest level of reliability and availability including diverse backup paths.

4  Substation Application Portfolio – 6 application groups exist in the substation and are logically partitioned over common transport ◦ Telemetry – RTU/IED – EMS/DMS communications (encrypted) ◦ CIP Telemetry – NERC CCA sites (encrypted) ◦ DA – Field Distribution Automation traffic aggregated by TGB (encrypted) ◦ Enterprise – Business applications ( , VoIP, surveillance video) ◦ Security – Card readers ◦ AMI – TGB backhaul handoff to Core PoP  Tier 1 – Substation will be a point-of-presence to the SONET backbone. ◦ SONET infrastructure provides Ethernet and TDM provisioning ◦ Routing capability to permit application provisioning over Ethernet (Layer 3) ◦ Quality of service management, data prioritization  Tier 2 – RF bridge between TGB’s and non-PoP substations ◦ WiMax/Ethernet transport ◦ VLAN partitioning per application for separation

6  Relay Protection Communications Parallel dual SONET ring configuration (OC3 & OC48) with PoP’s at each substation No relay channel failure with loss of a ring Path diversity – loop topology with fast switching to protected path OC3 ring – Primary Relay communications No other applications will use OC3 Static environment OC48 ring – Backup Relay, TDM & Ethernet service GigE provisioned to support Ethernet services TDM circuits for relay protection, voice & serial communications as required

7

8  Substation LAN Access switch – VLAN provisioned (Layer 2) No inter-application routing will be permitted Telemetry network access/authentication will be through core SCADA Firewall – NERC CIP compliant TGB’s and other substation IP devices will be connected to switch partitioned in their respective VLAN’s  Substation WAN Router (layer 3) will interface with switch and will provision Virtual Route Forwarding Tunnels (VRF) 6 VRF tunnels will be created for logical separation VRF tunnels will be encrypted using Dynamic Multipoint VPN (DMVPN) IP addressing schema will be defined for entire substation population based on application requirements

11  Transport the Smart Grid application portfolio ◦ AMI backhaul – 70 Aggregation pts) ◦ Distribution Automation Aggregation pts) ◦ Substation Telemetry (56kbps/substation) ◦ Voice/Video (~1Mbps per video stream)  Application Traffic Considerations ◦ Bandwidth consumption (5-20Mbps) ◦ Latency sensitivity (QoS tagging) ◦ Security (PKI) ◦ Logical provisioning of applications (VLAN tagging)

12 Spectrum Options – Licensed vs. Unlicensed Unlicensed (ISM) Free Limited Power Uncontrolled Noise Floor Uncontrolled Interference 900 MHz – Hi Noise 2.4 GHz – Hi Noise 3.65 GHz (Lite License) 5.X GHz Licensed High cost – Spectrum Market Strict FCC deployment rules High Power Operation Low/controlled Noise Floor Interference Remedy 700 MHz Public Safety 900 MHz 2.3 GHz

13  Free-space path loss is proportional to the square of the distance between the transmitter and receiver, and proportional to the square of the frequency of the radio signal. ◦ Higher the frequency – Lower the signal propagation ◦ What type of coverage are you planning for?  Blanket umbrella (target lower frequencies with minimal interference characteristics)  Surgical microcell (target higher frequencies)  Urban (target lower frequencies with minimal interference characteristics)  Suburban/rural (depends on the type of coverage, Blanket vs. Surgical)

16 Two prevailing backhaul Standards WiMax Long Distance 5-10 Miles P2P & P2MP Time Slotted Access Mobility ( e) 5-10 MHz Channels 802.1Q (VLAN, QoS) Security EAP/TLS/AES WiFi Shorter range 1-2 Miles Meshing capability Contention Access DSSS 22 MHz Channels 802.1Q (VLAN, QoS) Security EAP/TLS/WPA 2

17  Backhaul 100 AMI/DA collector sites  Provide backhaul of non-fiber substations  Requires surgical deployment, not blanket coverage ◦ Point-to-point links ◦ Microcell canopies  Decided WiMax using 3.65 GHz Lite-License ◦ Minimal noise at this time ◦ Do not require full territory coverage ◦ Point-to-point links where necessary
