Cost Distribution

Rate Structure Comparison

Flat Rate

Best for: Consistent usage patterns

Advantages: Simple billing, predictable costs

Disadvantages: No incentive for off-peak usage

Typical Range: $0.08 - $0.20 per kWh

Time-of-Use (TOU)

Best for: Flexible operating schedules

Advantages: Lower off-peak rates, grid benefits

Disadvantages: Complex scheduling, peak penalties

Potential Savings: 15-30% with optimization

Demand Rate

Best for: High usage, steady load

Advantages: Lower energy rates, rewards efficiency

Disadvantages: Demand charges, peak management

Break-even: Usually >100 kW systems

Industrial Rate

Best for: Large facilities, 24/7 operation

Advantages: Lowest unit costs, custom terms

Disadvantages: High minimums, complex contracts

Requirements: Usually >1 MW demand

Cost Optimization Strategies

Schedule Optimization

  • Shift operations to off-peak hours
  • Use programmable controls for automated scheduling
  • Coordinate multiple systems to avoid peak overlap
  • Implement load forecasting and planning

Demand Management

  • Install demand controllers and monitoring
  • Implement load shedding during peak periods
  • Use energy storage for peak shaving
  • Coordinate with facility-wide demand response

Power Quality

  • Improve power factor with capacitor banks
  • Install harmonic filters to reduce losses
  • Use high-efficiency power supplies
  • Implement voltage optimization

Contract Negotiation

  • Evaluate rate structure options
  • Negotiate custom rates for large users
  • Consider renewable energy contracts
  • Participate in demand response programs

Electricity Cost Calculation Formulas

Basic Energy Cost

Cost = Energy (kWh) × Rate ($/kWh)

Simple flat rate calculation for energy consumption.

Time-of-Use Cost

Cost = Σ(Energy_period × Rate_period)

Sum of energy consumed in each rate period times respective rates.

Demand Charge

Demand_Cost = Peak_kW × Demand_Rate

Based on highest 15-minute average power draw during billing period.

Total Bill

Total = Energy_Cost + Demand_Cost + Fixed_Cost + Taxes

Complete electricity bill including all components and fees.
