Abstract
Paper presents practical experience in evaluating adequacy of generating capacity by different regions in the Western interconnection. This includes analysis of uncertainties associated with load, intermittent energy sources and forced and maintenance outages on generating units and transmission facilities. The paper is a joint effort by the utility industry and Western Electricity Coordinating Council (WECC). Adequacy assessment of systems with ongoing integration of variable resources such as wind and solar has added new requirements to enhance the present methodologies and tools for computing the known Loss-of-Load-Expectation (LOLE) index. The LOLE index is influenced by load, generation, export/import, generation and transmission forced and maintenance outages, transmission operating constraints and various uncertainties related to load, generation and system operating conditions. Application of probabilistic approaches has already been used by industry and is accepted by a number of WECC member utilities. Adequacy indexes such as LOLE and Expected Unserved Energy (EUE) allow the meaningful assessment of the effective generating capacity margin and help utilities to determine if new resources are needed to meet reliability standard. This paper reviews the probabilistic approaches presently used by utilities in Western Interconnection in regard to planning and operating generating resources.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
