Metrics highlight variability in plant reliability, with some units showing significant deviations from budgeted performance.

REDACTED 1 Request IR-8: 2 3 Reference: Tab A6(2) 4 5 In rows 7-26, 11 out of 15 generating units had actual Heat Rates (column G) that were 6 than budgeted (column H). What is NSPI's view of the cause(s) of these results? 7 8 Response IR-...

AI summary NSPI explains that forecasted heat rates differ from actuals due to dynamic operational factors like real-time dispatch, cycling, and fuel quality variations. Adjustments from prior years' coal pile surveys also impact current heat rates, even if they relate to previous periods.

Request IR-4: - Reference: Tab A2NC - a) In cell F9, please explain the ~55% increase in output at Lingan 2, relative to 2024. - b) Is the overall reduction in gas production and increase in solid fuel production relative to 2024 due to th...

AI summary The text includes three questions from Request IR-4, asking for explanations regarding increased output at Lingan 2, changes in gas and solid fuel production linked to SO2 certificate of variance, and discrepancies in hydro capacity figures between noted and reported values in the 2025 system outlook.
