India is increasing the share of domestically sourced coal in power plants that are primarily supplied with imported coal, according to reports on ongoing supply changes. Business Line says domestic coal is currently used to operate about 5.7 gigawatts (GW) of power capacity this year out of a total 18.7 GW installed capacity that relies on imported coal. This corresponds to nearing the 50% mark for local coal usage within this import-fed segment. The report also states that trials are underway to expand the domestic coal switch to an additional 4.3 GW of capacity. The Economic Times similarly reports that India is close to using roughly half of the coal sourced locally in import-fed plants, reinforcing that the change is being phased in rather than implemented fully at once. Taken together, the coverage indicates a targeted effort to increase domestic coal blending or substitution in plants that were originally structured around imported fuel, supported by trial runs before further expansion.
