NEMA Premium® Three Phase Electric Motors
Incentive amount for NEMA Premium motors is $4 per horsepower. The electric motor incentive encourages the purchase of new energy efficient motors in lieu of rewinding. The program requires single-speed, three-phase, 10 HP to 500 HP, 1200, 1800 and 3600 RPM, squirrel cage induction motors, NEMA Design A or B, continuous rates. Eligible motors must meet or exceed the nominal energy efficiency levels presented below (based on IEEE Standard 112, Method B). Incentives do not apply to rewound or repaired motors. You must replace an existing three phase motor with a new qualifying motor of the same or smaller size. Customers must scrap the previous motor themselves or have it scrapped by their installer. The older inefficient motor cannot be rewound, repaired or brought back into circulation. Motors must operate a minimum of 1,500 hours per year. Pre-approval is not required.

Enhanced NEMA Premium
Incentive amount for Enhanced NEMA Premium motors is $6 per horsepower.
To qualify for an Enhanced motor incentive, the motorʼs nominal efficiency at full load must be at least 1% greater than the efficiency listed on these tables.
Examples:
“Enhanced” efficiency for a 15 HP, 3600 RPM motor must be at least 91.2%.
“Enhanced” efficiency for a 40 HP, 1200 RPM motor must be at least 95.1%.
“Enhanced” efficiency for a 100 HP, 1800 RPM motor must be at least 96.4%.
VARIABLE FREQUENCY DRIVES (VFD)
Incentive amount for VFDs is $30 per horsepower controlled.
Drives between 1 HP and 200 HP controlled applied on HVAC fans, pumps, cooling towers, and industrial fans, and that operative more than 1,500 hours per year qualify for prescriptive incentives. Redundant or back-up units do not qualify. Routine replacement of existing VFDs does not qualify. VFD speed must be automatically controlled by differential pressure, flow, temperature, or other variable signal. The system controlled must have significant load diversity that will result in savings through motor speed variation. Pre-approval is required for VFD incentives > $1,000. Drives controlling greater than 200 HP requires custom approval.
