Interregional electricity transfer falls 11 per cent in Q1FY26

The volume of interregional electricity transfer declined significantly by 11 per cent year-on-year during the first quarter (Q1: April to June) of current fiscal year FY26.

Latest statistics released by Grid Controller of India Ltd (GRID-INDIA) suggest that the total interregional electricity transfer during Q1FY26, at 62,911 MU, was 11.4 per cent lower than the comparable 71,038 MU in Q1FY25. [MU = million units = million kwh = Gwh]

There was a sharp decline in electricity transfer across the five regional grids – northern, western, eastern, southern and northeastern (denoted as NR, WR, ER, SR and NER, respectively.)

NR, the biggest importing region, saw a 13.7 per cent decline in imports from 31,090 MU in Q1FY25 to 26,833 MU in Q1FY26. Offset by a small drop in exports, NR was a net importer to a lesser extent of 21,501 MU in Q1FY26 as against 24,485 MU in Q1FY25. [NR is more of a consumption centre and does not have significant export volume. In Q1FY26, exports from NR were just 5,331 MU]

The biggest interregional electricity transfer takes place from WR to NR (denoted as WR-NR). This component saw a transfer quantum of 23,201 MU in Q1FY26, down 15 per cent from 27,301 MU in Q1FY25. Generally, the next biggest constituent, WR-SR, also saw its metric fall 15.8 per cent from 12,953 MU in Q1FY25 to 10,907 MU in Q1FY26.

SR was a net importer to the tune of 13,165 MU in Q1FY26 as against 17,119 MU in Q1FY25. This was the result of 12.7 per cent decline in imports to SR coupled with a 32.2 per cent rise in exports. [Though exports from SR rose appreciably, they were insignificant in absolute terms – 5,231 MU in Q1FY26.]

WR saw a sharp decline of nearly 16 per cent in exports, from 44,693 MU in Q1FY25 to 37,865 MU in Q1FY26. Exports from WR were stagnant across the two quarters. WR was a net exporter to a lesser extent of 27,243 MU in Q1FY26 as against 34,331 MU in Q1FY25.

 

Interregional transfer capacity

As of June 30, 2025, the country’s total interregional transfer capacity stood at 120,340 MW (or around 120 GW), up from 118,740 MW as of March 31, 2025. This increase of 1,600 MW was entirely due to augmentation on the ER-WR corridor, in turn due to commissioning of critical ISTS schemes by Power Grid Corporation of India Ltd (PGCIL).

Currently, the bulk of India’s total interregional transfer capacity lies on the WR-NR corridor – 38 GW out of the total 120 GW. Transfer capacities on the ER-NR, ER-WR and WR-SR corridors are roughly 22.5 GW each.
