Variable frequency drive applications & installation

Variable frequency drive on HVAC Chiller
Installation of a variable frequency drive on an existing chiller.

Installation of the variable frequency drive must accompany the permanent removal or disabling of existing flow control devices.
New chillers with integrated variable frequency drives may be eligible under the Air-Cooled and Water-Cooled Chiller incentive.
Variable frequency drives installed on new equipment are not eligible for this incentive.

Variable frequency drive on HVAC Fan or Pump ≤ 200 HP
Installation of a variable frequency drive on an HVAC fan or pump 200 HP or less. For motors larger than 100 HP, please complete the VFD Information sheet (not required for motors that are 100 HP or less).

Variable frequency drive on Pool Pump
Installation of a variable frequency drive on a pump 200 HP or less. For motors larger than 100 HP, please complete the VFD Information sheet (not required for motors that are 100 HP or less).

Installation of the variable frequency drive must accompany the permanent removal or disabling of existing flow control devices.
The variable frequency drive must be installed with automatic control technology.
The following variable frequency drive applications are not eligible:

Replacement of existing variable frequency drive
variable frequency drive installed on equipment which operates less than 1200 hours per year
variable frequency drive installed on redundant/backup motors
variable frequency drive installed in place of multi-speed flow control equipment (e.g., two-speed cooling tower fans)
variable frequency drive installed for the purpose of “soft-starting” motors
variable frequency drive installed on pumps where affinity laws are not in effect, such as sump pumps

The following variable frequency drive applications are not eligible for this incentive but may be eligible for a Custom Incentive:

variable frequency drive installed on a forward curve fan where inlet guide vanes are already present
variable frequency drive installed in place of variable pitch blade flow control equipment
variable frequency drive installed on a motor larger than 200 HP

variable frequency drive installation in a data center is not eligible for this incentive but may be eligible for a Data Center Incentive.

Variable frequency drive on Air Compressor, Industrial Process Fan or Pump ≤ 200 HP
Installation of a variable frequency drive on an air compressor, industrial process fan or pump 200 HP or less. For motors larger than 100 HP, please complete the VFD Information sheet (not required for motors that are 100 HP or less).

Air Compressor(s) with Integrated variable frequency drive ≤ 100 HP
Installation of new air compressor(s) with integrated variable frequency drive.

Installation of the variable frequency drive must accompany the permanent removal or disabling of existing flow control devices.
The variable frequency drive must be installed with automatic control technology.
The following variable frequency drive applications are not eligible:

Replacement of existing variable frequency drive
variable frequency drive installed on equipment which operates less than 1200 hours per year
variable frequency drive installed on redundant/backup motors/compressors
variable frequency drive installed in place of multi-speed flow control equipment (e.g., two-speed cooling tower fans)
variable frequency drive installed for the purpose of “soft-starting” motors
variable frequency drive installed on pumps where affinity laws are not in effect, such as sump pumps

The following variable frequency drive applications are not eligible for this incentive but may be eligible for a Custom Incentive:

variable frequency drive installed on a forward curve fan where inlet guide vanes are already present
variable frequency drive installed in place of variable pitch blade flow control equipment
variable frequency drive installed on a motor larger than 200 HP

Variable frequency drive installation in a data center is not eligible for this incentive but may be eligible for a Data Center Incentive.
Installation of new air compressor(s) with integrated variable frequency drive must have a total motor nominal HP of 100 HP or less.
Air compressors larger than 100 HP may be eligible for Custom incentives.
