New Greenhouse and Energy Minimum Standards Determination 2018 is implemented on 14th May 2019 and onwards. Both Minimum efficiency (IE2) and High efficiency (IE3) levels will remain but are aligned with levels in IEC 60034-30-1 Ed.1.0.
Scope is identical for the compulsory Minimum efficiency and the volutary High efficiency:
Single-speed, 0.75 up to but not including 185 kW
Voltage up to 1100 V
2, 4, 6, 8 poles
Safe area motors and motors for explosive atmospheres
Inverter duty motors that can be operated DOL
Motor efficiency must meet the specified level in AS/NZ 1359:5:2004 either at 100% or 75% load
The USA has been at the forefront in requiring minimum efficiency levels for low voltage motors. The current regulation, 10 CFR (Code of Federal Regulations), was published in June 2016 replacing the previous regulation, Energy Independence and Security Act (EISA), and was signed into law in 2007, revised in 2010. Generally the regulation is called as Integral Horsepower Rule (IHP).
The Integral Horsepower Rule (IHP) builds on the previous Acts, updating the mandated efficiency standard for almost all three-phase 2-, 4-, 6- and 8-pole AC industrial motors from 1 to 500 HP (0.75 to 373 kW). Motors covered by the regulation must be verified and certified by a competent third party e.g. UL or CSA then registered to Department of Energy (DoE).
The IHP applies to both NEMA and IEC motors manufactured or imported for sales in the United States. In addition, all motors destined to US shall bear a safety certificate marking, such as CSAus or UL, indicating the compliance with UL standards.
The Energy Efficiency Regulations, 2016 was published, along with the a Regulatory Impact Analysis Statement that came into force on June 28, 2017.
