August 12th-13th Quarterly Meeting
◦ A summary of the Final Clean Power Plan was presented. There are
interim compliance targets between 2022 and 2029. Mandatory
reductions will now occur in that time frame with a three-step
implementation approach
◦ There was a discussion about the future of the Base Case
Coordination System (BCCS). It is an online resource for
information to produce base cases. The contract for developing
the system was awarded to Siemens, and is now three and a half
years behind schedule. The System Review Work Group (SRWG)
has been fully involved in testing and voted to give BCCS a sixmonth extension. The Technical Studies Subcommittee (TSS),
SRWG’s parent committee voted later the same day to recommend
terminating the BCCS

RPCG meetings happen every other year depending on the needs of WECC members. RPCG is
not a “formal standing WECC Committee,” but is a member-driven effort to guide and assist
WECC staff in their planning efforts.
An RCPG–CCTA Process Meeting was held on April 28, 2015:
◦
◦
◦

Purpose of the RPCG is:



To solicit input on potential transmission projects with probability of being in-service in the next 10 years.
To assist with best-estimates on transmission topology.
Be stakeholder driven to reflect diversity of views.






Critical for WECC Interconnection-wide planning
Criteria-driven process (quantitative & subjective)
Stakeholder input before submittal to TAS
Valuable for future planning for Regional Planning Groups
Valuable for resolving inaccurate data/assumptions on transmission projects; inconsistency in modeling
assumptions and potential under/over estimation of transmission utilization/congestion levels.
Process results - 2400 miles of regionally significant transmission

Project kick-off in April 2015.
