- October 5, 2023
The total volume of interregional electricity transfer grew marginally by 2.3 per cent year-on-year during the first four months (April to July) of FY24.
The comparable growth in the first quarter (April-June) of FY24 was higher at 3.3 per cent.
According to latest statistics released by Grid Controller of India (Grid-India), the total electricity transfer amongst the five regional grids was 102,471 MU (million units or million kwh) in the April-July period of FY24. This was 2.2 per cent higher than the comparable level of 100,151 MU in the same period of FY23.
Exports from WR to NR (denoted as WR-NR) continued to be the biggest component of interregional exchange. At 31,989 MU the WR-NR component accounted for 31.2 per cent of the total interregional transfer between the five regional grids – NR, ER, NER, WR and SR.
Here are some more observations:
- WR saw a significant rise of 20.3 per cent in exports – from 46,467 MU in the April-July period of FY23 to 55,881 MU in the same period of FY24. With the result, WR was a net exporter of electricity during the April-July period of FY24, to the extent of 37,667 MU. The comparable figure for FY23 stood at 23,934 MU.
- SR appeared to be battling with self-sufficiency as the region saw a sharp rise in imports in conjunction with a decline in exports. While imports rose by 34.9 per cent, exports were 51.4 per cent lower. The net imports of SR grew substantially to 26,729 MU in the first four months of FY24, from 12,642 MU in the same period of FY23.
- Imports by SR from WR rose significantly by 71.3 per cent year-on-year in the April-July period of FY24.
- ER was a net exporter of electricity, to the extent of 20,618 MU in the first four months of FY24, as against 21,783 MU in the like period of FY23.
- Overall, three regions – WR, ER and NER – were net exporters of electricity while the remaining two – NR and SR – were net importers.
- NER regained its status as net exporter thanks to higher exports in July 2023. During the first quarter (April to June) of FY24, NER had turned net importer, albeit at a small magnitude.
- The ±800kV Raigarh-Pugalur HVDC line of Power Grid Corporation of India Ltd (PGCIL) continued to be the busiest corridor in the April-July period of FY24. This line ferried 9,000 MU of electricity from WR to SR. The reverse flow (SR to WR) was insignificant. The next busiest transmission system was the ±800kV Champa-Kurukshetra HVDC line, also of PGCIL. This line helped transfer of nearly 8,120 MU of electricity from WR to NR. There was no flow in reverse direction.
