These are questions that are frequently asked. If there are any other queries do get in touch with us.
1. What is the technology used in the 2 MW power stations?
Gasifier Technology. Biomass Gasification is the conversion of solid fuels (wood / wood-waste, agricultural residue) into a combustible Gas mixture called Producer Gas, through the process of partial combustion. The Gasifier is a chemical reactor in which the biomass gets dried, heated, pyrolysed, partially oxidized and reduced as it flows through it. This technology is highly efficient, clean and cost effective for power production.
2. What is the generation capacity of each of the two power stations?
Each of the power stations has a 2 MW power generating capacity.
3. Who are your equipment suppliers for the Gasifiers and engines?
Ankur Scientific Technologies Pvt Ltd, India's largest Gasifier manufacturer is the Gasifier supplier. The Gasifiers will be coupled with Cummins engines which are of international repute. Ankur will be the system integrators and will also be providing one year of O&M Services for the power stations post commissioning.
4. Why have you decided to go with Gasifier and not with steam turbine?
Gasifier technology is cleaner and more efficient than steam turbine, which has already been proved for smaller size power stations.
5. What are the locations of the two power stations?
The first power station will be in the SIPCOT industrial area in the Sivaganga district of Tamil Nadu. The second power station will come up in Arni Taluk of the Yavatmal district in Maharashtra.
6. Is this project eligible for RECs and Carbon Credit?
Yes. The project is eligible for both RECs as well as Carbon Credit.
7. How much wood is required to produce one unit of electricity?
Generally 1.1 to 1.2 kgs of wood is required for every unit of electricity to be produced. However, since the nature of raw material used in VVPL power stations is uniform with high calorific value, low ash content and uniform wood weight densities and burning properties, the wood requirement is expected to reduce to 1.0 kg per unit.
8. If the power stations are going to be fed completely by energy plantations, how many acres of plantations will be required for each 2 MW power station?
Every 150 acres of Man Made High Density Regenerative Forests with Fast Growing trees for Power Production can support 1 MW of power production for the lifetime of the power station. Hence, each 2 MW power station will require 300 acres.
9. What is the basis on which the biomass species has been selected? Where has the planting material been procured from?
Species for Energy Plantations are selected based on many factors, such as:
• Fast Rate of Growth
• Calorific Value > 4000 Kcal/Kg
• Good weight density
• Easily reproducible in large quantities in the nursery
• Vigorous coppicers
10. What is Just in Time harvesting?
One cannot harvest large quantities of biomass and store them for usage. This will result in logistical and storage problems. However, if one harvests a quantity "Just enough, for example, a 15 day storage" and harvests "timely to reach the end consumer", it will result in economic handling of biomass. This principle is called "Just – in – Time" harvesting. Just – in – Time Harvesting allows increased biomass availability due to the fact that uncut trees keep growing.
11. Does the raw material require any processing?
The raw material will have to be chipped into smaller sizes before it is fed into the Gasifier.
12. Is a large quantity of water required for the power stations?
Gasifiers do not require large quantities of water for operation of power stations. This results in significant savings of water resources.
