Base Case Coordination System (BCCS)
Request For Information (RFI)Presented by:
Randy Rhodes
David Franklin
BCCS RFIBCCS RFI
The purpose of this RFI is to seek information from Responders qualified to provide WECC with a software solution for improved management of transmission planning data at a central location and improved coordination of transmission planning base cases. SRWG/TSS is seeking to improve the existing process by automating planning case development and review that are now done manually. These improvements are expected to both improve planning model accuracy and reduce manpower requirements.
In this RFI, SRWG/TSS is seeking information that will likely be used in developing a Request for Proposal (RFP) to supply and implement this software.

Back Ground HistoryBack Ground History
In July 2006, SRWG Evaluated The Base Case ProcessSRWG (Randy Rhodes) Meetings with WECC RC In Vancouver, WAPCC/OC Conference Call Meeting – May 29th, 2009
OC agreed that a RFI would be the next step for BCCS

Planning FunctionsPlanning Functions
The two primary Planning deliverables are to deliver a construction plan and establish boundary operating conditions for the transmission system. To support these primary deliverables and other needs, Planners:
Validate/establish path ratingsRespond to generation interconnection requestsRespond to transmission service requestsPerform stability studiesExamine major transmission changesEvaluate system device changes/additions/deletionsSupport the WECC Annual Study ProgramSupport their company Integrated Resource Planning (IRP) processSupport TEPPC and other regional transmission planning needs

The current interaction process between Transmission Planners and WECC
A base case generally requires 14 weeks or longer from data request to posting the base case on WECC website.

Planning NeedsPlanning Needs
WECC's System Review Work Group (SRWG), as a representative of the transmission planning community, has tentatively established a set of needs and desired improvements to support the base case development process and aid the planning community as a whole. Needs and desired improvements are:
Improve data entry
Improve Area Coordinators Communication
Independent of Power Flow Format
Better data error checking and correction capability
Store current/future year topologies of the system
Add more automation to the planning process (less manual)
Potentially increase the number of yearly base cases
Be able to more efficiently make base case variations
To have a more centralized data base
Web based accessibility

BCCS ImplementationBCCS Implementation
WECC anticipates that this system could be hosted at the WECC facilities. The primary systems at that location include the EMS and associated model management environment. The following diagram illustrates the relationship between the BCCS and the WSM environment in the Reliability Centers in more detail.

SRWG’s Conclusion SRWG’s Conclusion
Conceptual BCCSAlthough there are programs available to potentially meet planning needs, further evaluation is required to make that determination.
West Wide System ModelA tool to meet operation’s needs and to develop validation base casesAlthough the WSM meets some planning needs, additional tools are required to fully address base case preparation issues. For example, but not limited to:
Model Voltages Below 100kVIdentify Facility Outages When The Snap – Shot is Taken of the SystemImprove Interchange DiscrepanciesImprove Communication Between Area CoordinatorsProvide the ability to build long term base cases
