This demand response system sizing calculator turns operational or financial assumptions into a transparent planning estimate for a demand response portfolio. Enter values that describe your own portfolio, review the main result and supporting metrics, and use the formula section to confirm how each input is applied. The tool runs entirely in your browser and is intended for early-stage comparison, budgeting, and scenario review rather than contractual settlement or final engineering design.
Delivered MW required = annual target ÷ (events × duration)
Enrolled MW = delivered MW ÷ (reduction rate × availability)
The result estimates enrolled flexible load needed to reach an annual curtailed-energy target.
Actual program sizing should use approved baselines, participant performance data, and local program rules.
A 1,500 MWh target over 30 two-hour events requires 25 MW delivered. At 35% reduction and 90% availability, enrollment is 79.37 MW.
Yes. Replace the defaults with values from the same operating period and keep every unit consistent.
Use the share of capability expected to be available when requested. Do not apply it twice if another input already includes outages or opt-outs.
Zero is accepted where it represents no energy, events, incentives, cost, or reserve. A denominator such as capacity, duration, or required performance must be greater than zero.
Enter percentages as displayed values, such as 90 for 90%. The calculator converts them to decimals internally.
No. It is a transparent planning estimate and does not capture every contract, network, behavioral, financing, or operational constraint.
