Smart Grid Benefits
What it is
Why
Utility Value Example
15MM/yr 58K tons of CO2 reduction Res
consumer savings up to 10
27MM/yr 29K tons of CO2 reduction
  • 12MM/yr
  • 3.5 yr ROI

21MM/yr Based on a 4hr blackout per year of a
transmission utility
Renewables optimization
Grid Mgt. optimization
Compensation for generation variability
Enable higher Renewable Penetration
Key to meeting RPS targets
Compensation for production variability
More KWH Sales
Utility savings are approximate annual savings

Wimax Secure Standards at Every Level
  • Crypto EEPROM credential and key store on meter
  • Dynamic digital signature across meter
    (AES-CMAC)
  • Secure login required to obtain Smart Grid
    Identity

SmartMeter Identity
Secure Digital Keys / Certificates
  • Certificate Authority w/Public Ken Infrastructure
    (PKI)
  • OCSP Server for x.509 Digital Certificate
    validation

Secure Authentication
  • EAP/TLS over RADIUS Authentication,
    Authorization and Accounting seamlessly
    integrated into PolicyNet

Secure Communication
  • DHE-HSS Diffie-Hellman Key Exchange (ephemeral
    MSK)
  • Message integrity, encryption, replay protection

Secure Data Transmission
  • WiMAX PKMv2
  • TLS (Transport Layer Security)
  • IPSec (Internet Protocol Security / Internet Key
    Exchange)
