18 QUALIFICATIONS See general qualifications on Pages Note: Rebate applications must be submitted within six months of dealer invoice for the equipment/material purchased. Program-specific qualifications Motors Only: n Equipment installed as a replacement unit, retrofit or in new construction is eligible. n Rebates are available for Enhanced Ultra-Premium efficiency, 1 to 200 horsepower, three-phase general purpose motors. Enhanced Ultra- Premium efficiency motors are at least 1 NEMA efficiency band above EISA n Rebates for fractional horsepower motors are not available. n Motors for spare inventory are eligible for rebates. n Minimum of 3,000 annual operating hours. VSDs Only: n For use with fans, pumps and blowers only. n Minimum of 3,000 annual operating hours. n Must be for new installations or failed variable-speed drives with bypass capability only. Replacing a working VSD prior to failure with a new VSD is ineligible for rebates. n Must control a system or process with a variable load. n Process must be automatically controlled; manual controls do not qualify. n Single-phase variable-speed drives do not qualify. n Installations where applicable code requires a variable-speed drive do not qualify. n Mechanical-type drives or gear boxes, Eddy Current drives and magnetic coupling drives do not qualify. n Variable-speed drives installed for soft starting do not qualify. n VSDs purchased for spare inventory do not qualify. MOTORS & VARIABLE- SPEED DRIVES Take advantage of MidAmerican Energy s rebates for high-efficiency motors and variable-speed drives to help commercial, industrial and agriculture businesses with energy and bill savings. If your system doesn t always run at the same speed, neither should your motors, and adding flexibility to your production process can make a big difference in operational efficiency. A variable-speed drive connected to your electric motor regulates the motor speed and torque of the motor-driven equipment to the process requirement, resulting in reduced energy consumption. Rebates are available for VSDs installed on fans, pumps and blowers. VSDs that are integral to the equipment are not eligible for rebates separate from the equipment rebate. Rebates for motors and VSDs cannot exceed 70 percent of the installed cost (materials and reasonable labor). You will receive the lesser of the rebate amount or 70 percent of installed cost. Motor and Variable-Speed Drive Benefits n Reduced energy costs n Improved plant efficiency and load factor n Reduced maintenance costs Additional Variable-Speed Drive Benefits n Precise control of process flow and pressure n Bypass capability when required VARIABLE-SPEED DRIVES Variable-Speed Drives EQUIPMENT Variable-Speed Drives Variable-speed drives in heating, ventilating and air conditioning are not eligible if required by applicable code (ASHRAE or IECC 2012). $40 per HP of motor driven Important note before purchasing or installing a VSD: Modern variable-speed drives contain integrated protective circuitry that can shut down the drive when it senses the input voltage is too low or too high, loss of a phase (e.g., unbalance) or the motor is overloaded. The typical input voltage tolerance is /- 10 percent, but some manufacturers offer drives with wider input voltage ranges. Some variable-speed drive applications may require an Inverter Duty-rated motor, particularly if the motor will operate at very low speeds; a motor's internal cooling fan is less effective at low speeds. Work with your vendor to purchase a drive that is compatible with the power quality and motors in your facility. 16
