The volume of interregional electricity transfer was 17.7 per cent higher year-on-year during the first four months (April to July) of FY25.
According to latest data released by Grid Controller of India Ltd (GRID-INDIA), the total volume of interregional electricity transfer during the April-July period of FY25 was 95,410 MU (million units or million kwh) as against 81,088 MU in the same period of FY24.
Electricity transfer from WR to NR (denoted as WR-NR) continued to be the biggest component of total interregional transfer in the first four months of FY25, with a share of for 40 per cent. The corresponding share in FY24 was lower at around 31 per cent.
Of the five regions, WR and ER were net exporters, while NR, SR and NER were net importers, during the April-July period of FY25 (also denoted as 4MFY25)
Here are some more highlights:
Imports by NR rose sharply by 32.4 per cent from 33,427 MU in 4MFY24 to 44,244 MU in the same period of FY25. With the result, NR was a net importer to the extent of 36,436 MU in 4MFY25 as against 23,417 MU in the same period of FY24. Much of NR’s imports have traditionally come from WR. Incidentally, NR recorded its highest-ever evening peak demand of 82,312 MW on July 23, 2024.
- WR saw a massive 37 per cent year-on-year increase in exports in 4MFY25, much of it destined to NR. With imports by NR growing by less than 1 per cent, NR was a net exporter of electricity to the tune of 43,455 MU in 4MFY25, as against 27,589 MU in 4MFY24.
Imports by SR remained almost unchanged year-on-year in 4MFY25. Exports by SR grew by 52 per cent, touching 7,181 MU in 4MFY25. This made SR less of a net importer in 4MFY25, with a level of 17,560 MU as against 20,024 MU in 4MFY24. Incidentally, exports by SR to WR grew by a significant 48 per cent touching 6,747 MU in 4MFY25 from 4,555 MU in 4MFY24.
- ER witnessed a rise in electricity imports coupled with a decline in exports during 4MFY25. This led to ER becoming a smaller net exporter in 4MFY25 with a quantum of 10,703 MU compared with 15,997 MU in 4MFY24.
NER, the smallest regional grid in the national context of electricity transfer, saw both imports and exports growing by over 40 per cent. In 4MFY25, NER was a net importer to the tune of 161 MU as against 145 MU in 4MFY24.
- The busiest interregional corridor was PGCIL’s ±800kV Champa-Kurukshetra HVDC line that transferred 9,885 MU of electricity from WR to NR, accounting for over a fourth of the total WR-NR transfer in 4MFY25. Incidentally, there was no transfer in the reverse direction.
