3. ‘Ad Hoc’ WIUFMP Cost Allocation Proposal
The Ad Hoc group presented their report to UFAS at a webinar meeting on January 25, 2017.
UFAS will work with PEAK to run various scenarios at different contribution factors and develop some sample data.

4. ‘Ad Hoc’ WIUFMP Cost Allocation Proposal
The allocation uses megawatt impact identified by the ECC caused by:
Off-path tags
Pseudo-Ties
Generation to Load (GTL)
non-zero ACE
for contributions of 10% or greater to congestion on the specific path

5. ‘Ad Hoc’ WIUFMP Cost Allocation Proposal
These impacts are accumulated each five minutes by source and sink BA for the associated Qualified Path for all COPS hours during a calendar month.
The monthly path accumulations are combined to provide accumulations for all four Qualified Paths for each BA for each month.

6. ‘Ad Hoc’ WIUFMP Cost Allocation Proposal
The cost of COPS and WIUFMP is determined for the year as presently implemented and spread to individual months based on a pro rata distribution of COPS hours for the month as is presently implemented.
The monthly allocation of cost is allocated to each BA based on the ratio of its monthly “all path” impact to the total monthly “all path” impact for all BAs.

7. WIUFMP and PEAK’s SOL Methodology
FERC approved the retirement of TOP-007-WECC-1a on March 10, 2017 with an effective date of April 1, 2017.
Path Operators met with PEAK to discuss if changes need to occur to the WIUFMP in light of the SOL Methodology change and the retirement of TOP-007-WECC-1a.

8. WIUFMP and PEAK’s SOL Methodology
Paths will still have a TTC but no SOL unless it is stability limited.
Ideally a Path’s TTC would respect all element SOLs such that the Path could be scheduled (with flow at) the TTC value with no SOL encroachment but this is not always the case.
Western Electricity Coordinating Council

9. WIUFMP and PEAK’s SOL Methodology
Path Operators looked at Next Hour and Current Hour scenarios.
For Next Hour:
The Path Operator would manage to the lessor of the Path TTC or an identified element SOL value (95%).
Discrepancies between these values will be reviewed and updated as appropriate.
Western Electricity Coordinating Council

10. WIUFMP and PEAK’s SOL Methodology
For Current Hour:
Path managed to prevent SOL encroachment only (95%) and not TTC.

11. WIUFMP and PEAK’s SOL Methodology
Discussed applicability of WIUFMP to non-Qualified Path elements that impact a Qualified Path.

UFAS Activities
UFAS continues to coordinate with PEAK to migrate the WebSAS program into the ECC.

13. Western Electricity Coordinating Council
UFAS Activities
Parallel operations began on March 1, 2017.
Actual USF events (via WebSAS) are generating a study in ECC for analysis.
PEAK will issue a comparison report in the future that UFAS will review and validate functionality.
PEAK continues to provide training to BAs/TOPs and is starting to reach out to Marketing entities.

14. Western Electricity Coordinating Council
UFAS Activities
Expect to implement the integrated ECC/WebSAS component by the end of the year.
PEAK encouraged WECC Reliability entities to log into the ECC and become familiar with the tool and its operation/capabilities as well as validate source/sink data.

15. Western Electricity Coordinating Council
UFAS Activities
UFAS needs to respond to the question of expanding the use of WebSAS (WIUFMP Step 4) into current hour and the expansion of the USF mitigation to other (non-qualified) element/paths.
