How to Use This Calculator
- Enter Peak Demand, Curtailable Load, and Capacity Payment.
- Set Energy Payment, Events per Year, and Event Duration.
- Adjust Demand Charge Rate as needed.
- Review the Total Annual Benefit ($) result.
- Use Capacity Revenue ($) and Energy Revenue ($) to inform your decision.

What each input means
- Peak Demand
- Your facility's peak demand.
- Curtailable Load
- Load you can curtail during demand response events.
- Capacity Payment
- Annual capacity payment for enrolled demand response.
- Energy Payment
- Payment per kWh curtailed during events.
- Events per Year
- Expected number of demand response events per year.
- Event Duration
- Average duration of each demand response event.
- Demand Charge Rate

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersPeak Demand = 1000, Curtailable Load = 200, Capacity Payment = 50, Energy Payment = 0.5 = 7 input(s) provided
- Calculate Total Annual BenefitTotal Annual Benefit42800 = $42,800
- Calculate Capacity RevenueCapacity Revenue10000 = $10,000
- Calculate Energy RevenueEnergy Revenue4000 = $4,000
