This mode is a combination of both the above modes, which proposes the use of
LPG for corrugation heating and grid-connected solar PV-based electricity for other
energy needs. The impact of this mode can be compared by the base mode and can
be seen as considerable improvements in ecological impacts. The details of EF and
cost are discussed in Table 21.
The product-wise results of this mode can depict the actual impact of using both
solar PV and LPG against the use of LPG alone (Mode 2). This makes it clear that the
total investment of this mode is less than Mode 1 but undoubtedly, greater than Mode
2. The ISI calculation of the industry based on this mode is calculated in Table 22.
The ISI of this mode lies between that of Mode 1 and Mode 2 and is far more than
the existing practices.
