Question:

Question 1 - Diesel Generators instead of Natural gas/Propane generators Explanation: As per LBC, only Natural gas/Propane generators can be used for backup. 

1. Natural gas/ propane gas are sparsely available in India. Less than 1% of the cities in India have piped Natural gas. Nagpur city, where the project is coming up does not have piped Natural gas/Propane gas supply. Hence setting up a Natural gas/Propane gas back up is not possible here. 

2. Ours is a Net zero energy project based on Solar PV and backed-up with electricity from the grid. Diesel Generators will only be used if both Solar PV and grid fail to provide electricity to the project. Based on our experience at other locations in India, we do not expect the Diesel Generators to operate for more than 1% of the operating hours in a year. 

3. Natural gas/Propane gas generators are incompatible with Flywheel UPS which are being incorporated for computer & emergency lighting. A flywheel UPS has a backup of 15 seconds before which the Generator must start. However, a gas generator of huge capacity of 4000 kVA (applicable to project) has a start up time of more than 1 min. As data is most critical for an IT industry, this time lag will result in failure of the whole system . On the contrary a Diesel Generator takes around 5 seconds to start making it the best choice for backup. 

Proposal: We propose the use of Diesel generator instead of Natural gas/propane gas generator due to the mentioned reasons. We propose to mitigate the cabron generated due to use of diesel generators by way of cabron offsetting. Our diesel generator engine/plant will confirm to local environmental and pollution control norms. 

Question 2 - LPG range instead of Induction range Explanation: LBC suggests use of Induction range instead of LPG range. Adopting Induction range for a project of such a large scale, will increase the electrical Load by approximately 1 MW. One of the reason for high connected load is also that Indian cooking is very heat intensive.This will call for setting up on additional 1 MW of Solar PV along with equivalent back up power provision. This will call for addtional land to set up the Solar PV plant. The assosiated carbon footprint for the set up will be high. 

Proposal: We propose to use LPG range instead of induction range. We propose to mitigate the cabron generated due to use of LPG based cooking by way of cabron offsetting. We are also exploring options to use bio-gas generated from food waste to partly power our kitchens (Cooking in Kitchens).

Answer:

1. Due to the very limited availability of natural gas and propane in your location, diesel generators may be used for emergency power systems.

2. An LPG range may not be used. Consistent energy demand from cooking must be addressed through renewable power, not combustion.
