Residential Billing - Bill Calculation Factors | Alabama Power

Bill Calculation Factors

Two elements factor into the base rate of your monthly residential power bill: Natural Disaster Reserve (NDR) and Energy Cost Recovery (ECR).

The Natural Disaster Reserve (NDR) is designed to adjust monthly billings to address the financial impact attributed to certain natural disasters. The NDR fee for Residential customers is $0.15/month, and for all other customers it is $0.37/month.

The Energy Cost Recovery (ECR) is the fuel charge, and is stated in mills/kwh. A mill is 1/10 of a cent; example: 29.689 mills = 2.9689 cents.

The pdfs below list the NDR and ECR rates for this year and previous years, for your reference:
