Information Management Subcommittee Report to the
San Diego, California
October 7-8, 2004
The Information Management Subcommittee is responsible for overseeing the work efforts of the
Energy Management Systems Work Group and the Data Exchange Work Group. Those two work
groups are instrumental in coordinating the operational security and functional capabilities of the
WECC SCADA systems and the WECC Operations Network.
NWPP requested a direct connection to the WON. They have been using PGE’s ICCP link. Due to
security issues, PGE would like to remove any external links. NWPP will therefore need its own ICCP
link and WON connection. NWPP is not a member of the WECC, however all members of the NWPP
except one are. NWPP requires access in order to monitor and report reserve sharing events. The IMS
approved a special exemption for WON connection to the NWPP. The DEWG will be revising the
appendix to the WON Connection Policy to reflect all the approved exceptions.
The EMS Work Group is developing an "Advanced Applications Coordination Policy." This policy
and the "recommendations" developed by the DEWG for use of the RC database are being coordinated
and completed. The policy and the recommendations will be posted together for membership review
later this fall.
IMS – Expansion and name change to “Critical Infrastructure & Information Management
Subcommittee.” posted and under due process for approval
Mission Statement for CIIMS
A new CIIMS mission statement was crafted to include the PSWG.
“CIIMS promotes security for critical infrastructure, data exchange, and control system policies within
the WECC to enhance coordinated interconnected system operations.” posted and under due process
PSWG Mission Statement and Scope:
The following is the mission statement for the PSWG.
“The mission of the PSWG is to advance physical security of critical transmission, generation, and
control facilities within the WECC.”
The scope for the PSWG would include the following:
1. Coordinate with the NERC Physical Security STDs
2. Assist in the development and implementation of NERC CIP STDs
3. Identify WECC specific STD requirements
4. Develop, periodically review, & revise (as appropriate) physical security guidelines for
5. Conduct forums and workshops related to the scope

EMS Work Group
The EMS Work Group under the leadership of Erika Ferguson:
Developing an Advanced Apps Data Exchange requirements document that includes:
o Limiting the amount and frequency of data exchanged to a reasonable level.
o Scan rates: external ICCP data shall be retrieved once a minute.
o Neighboring control areas will need to share data for 115 KV and above for 2 busses in
from the interconnection.
o Data for 230 KV and above will be made available for entire transmission system for all
Developing recommendations for the WECC members in response to the NERC NE
Disturbance Report recommendations:
o Guidelines for Alarm Management
o Business Case/Recommendations for DTS (Dispatchers Training Simulator)
o Dynamic/Static Reactive Reserve Management and monitoring tools.
The “white papers” being developed in response to the NE Disturbance Report are in final
review by the EMS Work Group. The EMS Work Group will be meeting in October for
final approval prior to posting for the WECC membership.
Data Exchange Work Group
The DE Work Group under the leadership of Dave Ambrose:
1. ICCP Security
WECC DEWG has formed a task force to investigate the requirements for deploying
secure ICCP on the WON. “Secure ICCP” has been recommended by the NERC
DEWG for all Reliability Centers on the Inter-Regional Security Network (ISN) by
11/1/2005. The only WECC node on the ISN is the EHV Data pool.
2. XML for data exchange
The WECC DEWG will be presenting an implementation seminar in Tucson on
November 3rd on the WECC Electric Industry Data Exchange Protocol V 2003.08.20 as
a standard for the exchange of periodic (scheduling, non-real-time) data within the
3. Control Area to Control Area data requirements
DEWG has developed a document discussing control area to control area options for the
exchange of real-time data in support of control area advanced applications.

4. Won & WECCnet failover testing
Failover testing of the WON was performed beginning at 10:00 MT on May 27th, 2004.
This test was required to validate the recoverability of the network after AT&T
converted the MCI portion of the WON. Testing revealed three problems that were
fixed during the testing period. The WON is fully capable continuing to transfer data
while sustaining multiple outages on its backbone system.
A second, one week long test of the WECCnet messaging system will be scheduled for
later this year.
5. Conversion of the east side of the backbone system to private utility digital microwave
The conversion of the east side of the WON backbone to digital microwave is very
nearly complete. The Phoenix to Loveland leg has been converted and the Loveland
to Vancouver, WA leg only needs to have the error rates reduced to go into service.
6. Server replacements
Two replacement servers were purchased for the EHV WebSite and the EHV data-
pool. These have been configured with the latest release of the software and are
