Latest Direction no. 73 notification F. No. A- 1 100 18/O t I 2021 -CAQM/ 827(DT) Dated 02.06.2023 of CAQM regarding usage of Diesel Generators / Dgsets / Gas Generators in Delhi NCR.
Major excerpts of this Notification for easy understanding
| S.No | Capacity Range of DG sets | System to be adopted for control of emissions | Regulations for use | Explantion |
|---|---|---|---|---|
| 1. | Power generating sets of all capacities running on LPG/Natural Gas/ Biogas/Propane/Butane | None | No restrictions (Even during periods under GRAP) | Point No. 1 of this notification is very clear in stating that if You Are using 100% gas-based generator which maybe running on LPG or PNG or Butane has no restrictions of running whatsoever even during GRAP periods. So if you are converting you’re newly bought or old CPCB 1 or CPCB 2 certified Diesel Generator you can run that without any kind of restrictions, as the notification clearly indicates that you do not need any other system for controlling emissions. This is possible with GenForce NGR system. |
| 2. | Portable DG sets (below 19 kW) | None | No restrictions during the periods, other than restrictions under GRAP. Not to be permitted during periods of restriction under GRAP. |
Point No. 2 explains that generators under 19 kW that is up to 24 kVA also do not require any control on emissions. These generators can run without any restrictions other than GRAP periods. So these generators cannot run during GRAP period. However, it will be possible to run without any restrictions even during GRAP period with GenForce NGR system. |
| 3. | 19 kW to less than 125 kW | Dual fuel mode (Natural Gas & Diesel) | No restrictions during periods other than under GRAP. To be permitted to run for maximum 2 hrs. in a day during restrictions under GRAP subject to methodical maintenance of log of operation of DG sets, preferably in a digital mode. |
Point No. 3 tells us how to run Diesel Generators from 25 kVA to 156 kVA. It states that the generators should have bare minimum Dual Fuel mode that is with natural gas and diesel. Those generators having Dual Fuel mode can run without any restrictions other than GRAP period and for a maximum of 2 hours ( along with the maintained daily log book ) during GRAP period. Genforce DFS is available for Duel Fuel Mode operations . However, in this band of diesel generator ratings, Genforce NGRS is also available. With Genforce NGRS, there will be no restrictions on running even during GRAP period. |
| 4. | 125 kW to less than 800 kw | Dual fuel mode and Retro-fitted ECDs through certified vendors / agencies |
No restrictions (Even during periods under GRAP) | Point No. 4 clearly states that Diesel Generators above 156 kVA to 1000 kVA will have to use Duel Fuel mode and RECD (from certified agencies). After the installation of both these devices, these diesel generators can then run with no restrictions even under GRAP period. |
| 5. | 800 kW and above | Dual Fuel mode or Any other emission control device/ System Strictly subject to compliance for stack emissions as in the footnote. |
No restrictions during periods other than under GRAP. To be permitted to run for maximum 2 hrs. in a day during restrictions under GRAP subject to methodical maintenance of log of operation of DG sets, preferably in a digital mode. | Point No. 5 states. The emission controls to be adopted for generators above 1000 kVA. For generators Above 1000 KVA, It is mandatory to install either Duel Fuel mode or any other emission control device like RECD along with the compliance of stack emissions. These generators can run without any restrictions other than GRAP period and for a maximum of 2 hours ( along with the maintained daily log book ) during GRAP period. |
| 6. | New power generating sets of all capacities up to 800 kW procured to the standards as in MoEFCC notification No.Q-1s017losl 2OL2-CPW and GSR 804(E) dated 03.1 1 .2022 | None | No restrictions. (Even during periods under GRAP) | Point No. 6 states that all Diesel Generators which are CPCB4+ certified, do not further require any kind of emission control device and will have no restrictions of running even during GRAP period. |
