TEPPC Review Task Force
Notes from January 11, 2016 Meeting
Revised January 19, 2016
Boundary Conditions (from Jim Robb)
1. Assume that WECC will not take on NERC-registered entity function (i.e., Planning Coordinator
function), absent direction from NERC
2. Start with an assumption that we don’t want to take on any FERC Order 1000-related
compliance obligations. Provide support for those RPGs that have those obligations.
3. Make sure the work we’re doing has a very strong reliability hook (consistent with Section 215
funding); any variance would require serious discussion with the Board

TEPPC Strengths

WECC brand - impartial objective/ stakeholder-driven organization

WECC is a leader/pace setter for other reliability areas

Compare inputs to complete analyses from an Interconnection-wide perspective

Open stakeholder process

Independent perspective

Only entity with Interconnection-wide perspective

Consistent/ reliable funding through 215 process

Dedicated participation from real experts from throughout the Interconnection

Commitment to transparency and inclusion

Environmental data review process
TEPPC Opportunities

Common accurate data base across models

Anchor Case

Understanding and responding to change (e.g./ technologies)

Understanding and responding to reliability risks

Understanding and responding to physical and cyber security (Need to think about the
appropriate role for TEPPC)

Formulate coherent snapshot of the Western Interconnection for use in future stability
analyses

Analyze potential risks of large PV penetration (large-scale trip of inverters)

Improved coordination with Regions

Outreach to stakeholders re: desired products/services
TEPPC Challenges

Complete reliability assessment (beyond PCM only)

Ensure that activities meet Section 215 funding requirements


Resolve competing interests for data release; ensure data security and appropriate data release

Change in general (change management, scope and pace of change)

Perceived limitations on TEPPC's activities - budget or past activities

Keeping up with changes in the system (e.g., reduction in load on distribution system, growth of
renewables)

Efficiency- prioritizing requested work

Potential duplication of work (e.g., reliability analyses)

Relevance - keeping TEPPC and its products relevant to stakeholders' needs (e.g., entities doing
their own modeling)

TEPPC role WRT FERC Order 1000 – Regions are legally responsible, WECC is not

Software development risks (e.g., BCCS)
Follow Up/Action Items
1. Define distinction between reliability and economics
2. Identify RPG timelines vis-à-vis timeline for WECC planning needs
3. Determine right time/way to get input from other TEPPC customers (transmission owners and
transmission providers)
4. Identify opportunities to gain efficiency with TEPPC and PCC

Consider needed process changes for gathering and managing load, resource and
transmission data

Consider options to increase consistency in models, data and assumptions

Consider combining the two committees into one (would require Board action)?
5. Refine/revise TEPPC Value Proposition
6. Consider options for data release—test assumption that data can’t be used effectively unless
it’s totally transparent
7. Consider new products/services that may be appropriate for TEPPC to offer
8. Develop additional detail of the Western Planning Regions' (WPRs’) proposal that TEPPC use
each region's transmission plan-based "snapshot" power flow case to create an 8,760-hour
"anchor" grid simulation case (e.g., a future year Gridview case).

9. Develop a plan to fill in the “white space” in the U.S., British Columbia, Alberta and Mexico that
is not covered by Western Planning Regions (WPRs)
10. Create web site for TEPC Review Task Force
