  • Please review step numbers and references for accuracy
  • Please provide location on WPP Website of example files (not sure if a location exists yet for these referenced examples, but general location on website should be referenced).

  • 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.

SRP suggests expanding the example spreadsheet posted on the WPP website to include all steps (1-6) rather than the current subset of steps 1-5.

The text in 3.2. should refer to step 3.1 and the text in 3.3 should refer to step 3.1 and 3.2. The first sentence in step 4 should refer to step 3.2 and step 2. The text should also say the output. The text in in 6 should say the Load Growth Factor will then be applied to the results of steps 1 through 5.

Why is the P(50) Load methodology different for Summer vs Winter?

Labeling Table 2 with the specific Summer Season to which the example data applies would increase clarity.  

The references to previous steps in this section need to be double checked.
