3.24 The share of non-coal sources in the generation mix ranges between ~20% and ~26%. Considering the
capacity addition in RE, it forms the bulk of non-coal generation. The share of coal-based installed capacity
increases from ~40% in 2027 to ~56% in 2030 due to capacity additions (Exhibit 3.10 and 3.11). Generation
from coal increases from 954 BU in 2017 to about 2354 BU in 2030.

3.25 As per the calculations of this exercise, by 2025-26, existing coal capacity would not be adequate to meet
the demand, especially considering that some amount of coal-based capacity is being retired between 2022
and 2027. Thus, to meet the demand, coal-based generation capacity is likely to increase to 230 GW in
2024–25 to 474 GW in 2029–30. (Exhibit 3.12). Thus, the PLF of coal-based power plants follows a declining
trajectory from 64% in 2014-15 to 53% in 2018-19 and thereafter shows an upward trend, reaching upto 78%
in 2025 (Exhibit 3.13). It is then capped at 78% in view of diversity of demand, planned maintenance and forced
outages. The lowest PLF attained during this period is ~53% in 2019.
