  1. MV90 IP Data Transport ERCOT Recommendation John Fisher & Jeff Maddox

  2. Option 1 – ERCOT WAN • MP IP meters are located on MP’s private network • MP NAT translates the IP Meters to an ERCOT WAN IP Address • ERCOT polls meters over the ERCOT WAN

  3. Option 2 - Internet • MP IP meters connect to MP network • MP presents IP meters to ERCOT through an Internet routable IP address • ERCOT polls meters over the secure encrypted IPSEC tunnel

  4. Notes • Permitting IP meters access to the Internet increases risk • Man-in-the-middle attacks • IP spoofing • Exposing meters to SCADA based attacks (vulnerabilities are an unknown at present) • Private networks are more secure and more reliable • Private networks are isolated by the Service Provider from unauthorized users
