Understanding how Mississippi Power billing works helps you anticipate your bills, catch errors, and manage your electricity costs more effectively. This guide covers the complete billing process from meter reading to payment.

Mississippi Power bills residential customers monthly, with bills typically generated a few days after your meter is read. The billing cycle is approximately 30 days, though it can vary slightly.

Meter Reading and Billing Cycle

Your billing cycle begins and ends with a meter reading. Mississippi Power reads meters on a regular schedule, typically the same approximate date each month. Most customers have smart meters that transmit readings automatically.

After your meter is read, Mississippi Power calculates your bill based on the kWh difference between the current and previous readings. Your bill is usually generated within 1-3 days of the meter reading and mailed or posted to your online account.

Rate Calculation

Mississippi Power calculates your charges using the tiered rate structure:

  1. Base charge: $1.60/day × number of days in billing period
  2. First 650 kWh: Usage × first-tier rate
  3. Next 350 kWh: Usage × second-tier rate (if applicable)
  4. Over 1,000 kWh: Remaining usage × third-tier rate (if applicable)
  5. Fuel cost recovery: Total kWh × current fuel rate
  6. Taxes and fees: Calculated on subtotal

The rates used depend on the season (summer, shoulder, or winter) based on when your billing period falls.

Due Dates and Late Fees

Your bill is typically due about 20 days after it's generated. The exact due date is printed on your bill. Mississippi Power offers several payment options:

  • Online: Through your Mississippi Power account
  • Auto-pay: Automatic bank draft or credit card
  • Phone: Pay by phone with card or check
  • Mail: Send check with payment stub
  • In person: At authorized payment locations

Late payments may incur a late fee and could eventually result in service disconnection if not addressed.

Budget Billing Option

If you prefer predictable monthly payments, Mississippi Power offers a budget billing program. This averages your annual electricity costs into equal monthly payments, smoothing out seasonal variations.

Budget billing is recalculated periodically (usually annually) to ensure your payments align with actual usage. You may see a true-up adjustment if your usage was significantly higher or lower than projected.
