FREE TOOL

See the 30-minute interval that set your demand charge.

Upload your ComEd interval data and a few numbers from your bill. Phantom Grid reconstructs the demand charge from your own data and reconciles it to the bill, to the cent. No signup, nothing to sell.

Available for ComEd commercial accounts (demand billed). ComEd territory only for now.

ComEd interval data (CSV)

The 30-minute interval export from your ComEd account. It stays private: it is read once to find the peak and is not stored.

Your bill’s service period. Look for “Service from [start] through [end]” and enter both dates exactly as shown.

Billing period start date

The “service from” date.

Billing period end date

The “service through” date.

Delivery class

Find the “Retail Delivery Service” line on your bill; the kW band next to it is your class. Secondary voltage.

Billed demand (kW)

The kW on your demand-charge line.

Phantom Grid reconstructs what your bill already reflects. It does not recommend, project savings, or sell anything.
