Irrigation & Agriculture Incentives

Inland will accept claims for reimbursement for verified energy savings of energy efficiency upgrades to new or existing irrigation systems and water management measures. Download and fill out the "Rebate Form" below to see if you qualify.

VFD Requirements and Specifications

This measure applies to pumping operations that deliver, distribute or transport irrigation water with VFDs 500 hp or less (see custom project process for pumps exceeding 500 hp). Eligible installations include turbine pumps with substantial variation in flow rates (e.g., 20% or more) or discharge pressure requirements (e.g., 10% or more). New VFD installations must meet IEEE 519 standards.

Documentation Requirements:

Identification and location address

Pump Type (centrifugal or turbine)

Date of install

Application type (e.g., well or booster)

Operational hours per year

Pre-install billing history for two full seasons prior to install

Post-install billing history for one full season after install

Utility meter number

Pump TDH rating and flow rating (gpm)

Field elevation differences (as a percentage of total dynamic head)

Flow requirements changes (as a percentage of total flow rating)

Acres under irrigation system

Estimated site savings kWh

Name and version of VFD spreadsheet software or model used to estimate kWh savings

Estimated project cost and BPA credit/incentive

Inland shall reimburse $50 per installed HP.

Approval Process

All irrigation rebate requests must be pre-authorized by contacting the conservation department. Once approved, your rebate will be assigned a confirmation code which will reserve funding for a 90-day period.

Installation must be completed and required documentation must be received within this reserved time period to be eligible.
