Bi-Directional Meter
When Ameren Missouri receives completed Sections E - F, the bi-directional meter will be scheduled for installation. You will know the bi-directional meter has been installed when you see a red sticker that reads "Warning Alternative Generation Source." You may begin operating your generation at that time.

  • A one-time charge for the bi-directional meter of $281 for a 1-phase meter or $187 for a 3-phase meter will appear on your Ameren Missouri bill in the next billing cycle.
  • Your Ameren Missouri bill will reflect net metering from the day the bi-directional meter is installed. A net metering bill uses a full page bill format. Occasionally, the first net metering bill will be postcard format if you have received postcard bills in the past. 

Bi-directional meter only records billing data. It does not record the total amount of energy produced by the renewable system.

  • Only kilowatthour (kWh) fed back to the grid and kWh delivered by Ameren Missouri will register on the bi-directional meter.
  • If system is producing power and the property is using the power simultaneously, the bi-directional meter does not record the produced or used power - essentially they cancel each other out.
  • Optional monitoring systems are available to measure all energy produced by the generation. Talk with your installer for more information on this option.

G.  Application Approval
Once completed Sections A - F have been received by Ameren Missouri and the bi-directional meter has been installed, Ameren Missouri executes Section G and sends the customer a copy of the fully executed agreement.

  • If modifications to the current system are made at any time, it is your obligation (according to the Net Metering terms) to notify Ameren MIssouri and update/re-file your Net Metering Application/Agreement.
  • If the property is sold, the new owners will need to file a Net Metering Application/Agreement with Ameren Missouri in their name.
