COMMENT FOR BPM 103 - Participant Forward Showing Capacity Requirements

Submitted June 17, 2024, 11:12 a.m.





01: Please supply any comments related to the Introduction or Definitions sections. (1)

No comments

02: Please supply any comments on the Demand Response Utilization section. (2)

No comments

03: Please supply any comments on the FS Capacity Requirement section. (3)

No comments

04: Please Supply any comments on the P50 Peak Load Forecast section. (4)

No comments

05: Please Supply any comments on the P50 Peak Load Forecast - Winter P50 Peak Load Forecast section. (4.1)

After Step 4 the BPM refers to the WPP website for an example spreadsheet. PGE suggests adding the actual weblink to the example spreadsheet in the footnote for easy access.

06: Please Supply any comments on the P50 Peak Load Forecast - Summer P50 Peak Load Forecast section. (4.2)

  • Suggest considering making Step 1 of the summer method the paragraph: “Determine the peak load for each Month of the Summer Season…..”. This would be similar to the way Section 4.1 is organized.
  • Correction to Step 3.2: “The Load Forecast Ratio for each Month of the Summer Season is the result of step 4.1 divided….”. This should refer to step 3.1 instead of step 4.1
  • Correction to Step 3.3: “The Load Forecast Ratio (…) is the result of step 4.1 divided by the MW value identified in step 4.2”. This should refer to steps 3.1 and 3.2.
  • Correction to Step 4: “Multiply (…) from step 4.3 by the result of step 3.” This should rather say “Multiply (…) from step 3.3 by the result of step 2.  
  • Correction to Step 4: The example calculation of 2411MW provided for September is not correct: 0.68 * 3571 = 2428MW
  • Correction to Table 2: the numbers in the column  “Monthly P50 Peak Load Forecasts” are not correct. For example 0.88 * 3571 = 3142 and not 3136.
  • Suggest adding a footnote with a weblink to the exact location of the “example spreadsheet showing steps 1 through 5” instead of generically stating the it is posted on the WPP website.

07: Please supply any comments on the Load Growth Factor section. (5)

No comments

08: Please supply any comments on the Load Growth Factor - Established Growth Rate section. (5.1)

No comments

09: Please supply any comments on the Load Growth Factor - Participant Alternative Growth Rate section. (5.2)

Comment 1:

Regarding the paragraph: “…, the Participant will demonstrate that the alternative growth rate results in a peak load forecast 5% higher or lower than the peak load forecast calculated using the appropriate established growth rate discussed in Section 5.1.”

What is the basis for the 5% threshold? The approved FERC Tariff does not provide for an alternative peak load forecast limit.

PGE has concerns regarding the materiality of the 5% threshold because, based on the magnitude of an entity’s load in future years, the 5% can be very significant. PGE recommends removal of the 5% threshold and instead, the PO/PA require that participants submit detailed documentation to demonstrate the reasoning for their alternative load forecast. The PO/PA can reserve the right to deny if the Participant’s documentation does not support their alternative load estimate or if it is not materially different from the PO/PA provided estimate.

Comment 2:

Suggest providing a weblink for more direct access to the alternative growth rate request form.
