13 Request IR-4: - 14 The distribution line loss factor calculated in Cell C30 looks to be the average line loss over the 15 past three years and the line loss used in the GRA. The Board understands that the GRA line loss 16 factor was bas...
AI summary The Board is questioning the methodology used to calculate the distribution line loss factor in the GRA, specifically whether line losses for 2023/24 are being included twice in the rolling average, and is requesting an explanation for the rationale behind this methodology.
21 Response: 22 a) The Utility acknowledges the reasonableness of this suggestion, but in such case 23 suggests that that the GRA value, representing two years of data, should then be double 24 weighted in the calculation. This would reduc...
AI summary The Utility agrees with the suggestion but proposes double-weighting the GRA value, which represents two years of data, to adjust the loss forecast from 4.63% to 4.59%, and further reduce average line losses to 4.41% after additional adjustments.
16 Response: 17 a) The Utility understands that year over year and over a longer term, consumption per 18 customer and individual load factors change due to many factors. The Utility has not 19 conducted any study to analyze such changes....
AI summary The Utility acknowledges that customer load factors change over time but has not conducted a study on these changes. For the GRA, recent billing data and forecasts were used to estimate load factors and customer growth, and TOLEU considers this approach reasonable for a few years, with a review planned in the next GRA.
