Through this amendment, the Ministry has notified the emission limit for new diesel engines, Engines based on dedicated alternate fuels, Portable Generator sets etc used for power generating set applications up to 800Kw gross mechanical power.
Emission limits are applicable to both constant speed and variable speed gensets and genset engines used primarily to operate an electrical generator or alternator to produce and supply electric power for other applications in lieu of supply of power from electric grid.
An Electric Generator is defined as Portable if it suits the definition and satisfies the following condition.
A portable generator is the combination of an electrical generator and an engine (prime mover) mounted together to form a single piece of equipment. This combination is also called an engine-generator set or a gen-set which usually can be moved, pulled, pushed by a person and not build permanently into a structure such as power house or station.
Portable Electric Generator, a generator which satisfy the following condition.
- Power output is up to 19 kW & up to 800 cc engine displacement
- Power by PI air cooled engine
- It is on Hand-cart mounted units.
Definitions, Administrative and Test procedure for measurement of emission of visible and gaseous pollutant and particulate matter shall be as per procedure laid down in ―System and Procedure for Compliance to Emission Limits for Power Generating Set Applications and as amended from time to time.
These conditions shall apply to all new engines for power generation application and products manufactured, assembled or, imported to India, operating at constant or variable speed as the case may be:
Provided that these rules, shall not apply to
a. Any engine or, product, assembled or manufactured or imported, as the case may be, for the purpose of export outside India, or;
b. Any engine or product intended for the purpose of sample limited to four in number and to be exported back within six months of completing the sample testing, and not for sale in India.
c. Any engine or product, assembled or manufactured or imported, as the case may be, for the purpose of research & Development testing which shall be scraped or re-exported.
Every domestic manufacturer, importer or, assembler (hereinafter referred to as manufacturer) of engines for power generation up to 800 kW and engine displacement > 800 cc. and portable gensets up to 19 kW and engine displacement up to 800 cc, shall obtain Type Approval from authorised certifying agency and also comply with Conformity of Production (CoP) test of their product(s) for the emission limits which shall be valid for the next CoP year.
