4CP charges make up 40% of commercial energy bills in Texas. Missing one interval costs $50,000+.
Four Coincident Peak charges are based on your demand during ERCOT's single highest 15-minute interval each summer month. One missed curtailment = $50,000-200,000 in extra charges.
Peak demand doesn't always occur on the hottest day. Grid conditions, renewable output, and forced outages all play a role. You need real-time grid intelligence, not guesswork.
Energy managers waste hundreds of hours each summer watching load forecasts. Despite the effort, most still miss 1-2 peaks per year.
0-100% probability updated every 5 minutes. Know exactly how likely the current interval is to be the monthly peak.
Machine learning model combines weather, historical patterns, and current grid conditions to predict peak probability days in advance.
See how actual system load compares to ERCOT's forecast in real-time. Critical for identifying when peaks are likely to occur.
94% accuracy in identifying monthly peaks. Backtested against 5 years of ERCOT data with full transparency.
Alert 1: "When 4CP_probability > 50%" → "Email facility managers"
Alert 2: "When 4CP_probability > 75%" → "Pre-curtail non-critical"
Alert 3: "When 4CP_probability > 90%" → "Full curtailment mode"Staged alerts ensure you're prepared without over-curtailing. Save $150,000+ annually on transmission charges with proper peak avoidance.
