42Hz recommendations · ranked by ROI
#1−$3.8M
Pre-stage 72 kV bushing now
Cuts MTTR 41% if winding event materializes. APG lead is 30 weeks — order before May 2.
#2−$1.6M
Auto-shift 14 MW T2→T1+T3
Already armed in switching plan. Apply in current state to remove SLA exposure window.
#3−$0.4M
Tighten 87T-2 trip threshold
Faster differential pickup reduces blast radius ~22% in cascade simulations.
