VFD Incentives

A Perfect Motor Match

Start planning your project and take advantage of some of our highest incentives ever.

A variable frequency drive (VFD) controls the rotational speed of a motor by controlling the frequency of the electrical power supplied while not affecting the quality of the system. Typical motors have two settings, on and off. Allowing a motor to match output based on the demand of the equipment allows the motors to save energy by working at a lower speed during less demanding times.

Ameren Illinois offers great incentives for new projects that add VFDs to motors on fans or pumps. We can cover up to 80% of the project cost, allowing for a quicker payback on projects.
