What You Can Do

Transform raw charging data and market projections into actionable infrastructure capacity plans that balance capital expenditure with grid stability. You'll characterize load profiles by time and location, forecast peak demand periods that drive infrastructure requirements, and generate optimization recommendations for transformer sizing, feeder capacity, and DCFC unit mix based on duty cycles and growth scenarios.

Features

Analyze when, where, and how much power will be demanded across charging networks

Peak demand forecasting

Predict constrained periods and grid impact during high-utilization events

Capacity optimization

Right-size transformers, feeders, and DCFC units based on duty cycles and growth projections

Time-of-use (TOU) pricing modeling

Forecast utilization pattern shifts and revenue impacts from dynamic pricing strategies

Utility interconnection analysis

Generate grid impact studies and infrastructure upgrade requirements for regulatory filings

Demand response scenario planning

Model network behavior during grid constraints and peak shaving events

Infrastructure cost-benefit analysis

Calculate transformer upgrade timelines and ROI for phased capacity expansion

Example Output

Example 1: Corridor Capacity Plan

Input: 50-station charging corridor with 30% DCFC/Level 2 mix, 3-year growth forecast

Output:

  • Peak demand profile: 4.2 MW during 6-8 PM weekdays, 2.1 MW off-peak
  • Transformer requirement: 5 MVA with N+1 redundancy (two 2.5 MVA units)
  • Feeder sizing: 350 kcmil copper, underground conduit
  • Year 1-3 phasing: 15 stations per phase, upgrade timeline by year
  • Cost estimate: $2.1M infrastructure, $340K/year operating

Example 2: Demand Response Modeling

Input: Fleet depot with 200 vehicles, 2-hour charging window, grid peak avoidance contract

Output:

  • Baseline demand: 8 MW continuous charging
  • Peak shaving scenario: Stagger charging to 6 MW max, extend window to 4 hours
  • Revenue impact: $85K annual demand response payments vs. $120K added OpEx
  • Grid stability: Reduces local substation load by 25% during peak hours
