Overview

What it does.

The program can support efficient equipment, controls, and design decisions before a new building or major construction project is completed. Early contact is important because design assistance and preapproval occur during project planning.

Best for: A new commercial, institutional, or multifamily project still in design or early construction.

Eligibility

Application

How to start.

  1. Contact Ameren Illinois while the project is still being designed.

Planning notes

Limits to account for.

Disclose other utility or public incentives during project review.
