WECC (West)
Curtailment-heavy: structural, not fixable
65% curtailment-suspect
WECC underperformers skew toward California spring oversupply curtailment. Gap signals here reflect structural grid congestion; equipment interventions are unlikely to close the gap. Median gap: -30.7% among 85 underperformers.
vs.
SERC (Southeast)
Zero curtailment overlap: most actionable
0% curtailment-suspect
SERC has no curtailment flags in this screen. Every underperformer here carries an unexplained residual gap; the signal is consistent with module or inverter degradation. Median gap: -27.2% among 67 underperformers. These are the most actionable acquisition targets.
