Interregional electricity transfer grows 3.5 per cent in Apr-Feb FY23

 

The total volume of interregional electricity transfer during the first eleven months (April to February) of FY23 grew by 3.5 per cent, on a year-on-year basis.

The total quantum of electricity transfer stood at 214,417 million kWh (million units, MU) in the April-February period of FY23 as against 207,228 MU in the same period of FY22.

 

Here are some observations based on official statistics released by Grid Corporation of India Ltd (formerly, Power System Operation Corporation Ltd), pertaining to the April-February period of FY23 and FY22.  (The five regional grids – north, east, west, south and northeast – have been abbreviated as NR, ER, WR, SR and NER, respectively.)

• NR and SR continued to be net importers of electricity, while the remaining three – ER, WR and NER – were net exporters.

 

• Electricity imports by NR declined 7.8 per cent in FY23 (Apr-Feb) to reach 92895 MU from 100728 MU in the April-February period of FY22. Also, exports of electricity from NR grew by 14.5 per cent. Despite NR being a net importer of electricity, the magnitude of net imports fell to 63,872 MU in FY23 (Apr-Feb) from 75,390 MU in the April-February period of FY22.

 

• WR was less of a net exporter in FY23 as compared with the previous year. This was due to a sharp 21.6 per cent rise in imports, compounded by a 7.3 per cent decline in exports. Net exports by WR fell to 39,065 MU in FY23 (Apr-Feb) from 55,648 MU in FY22 (Apr-Feb).

 

• SR witnessed an increase of 8.4 per cent in imports. However, exports grew by a significant 30.1 per cent year-on-year during FY23 (Apr-Feb). Nevertheless, SR maintained its net import level of around 35,000 MU during the first eleven months of FY23.

 

• ER showed a net export level of 57,986 MU in the April-February period of FY23, slightly higher than the 54,820 MU in the same period of FY23.

 

• NER saw a big improvement in its net export level. Exports from NER to other regions grew by 35.5 per cent to reach 5,114 MU in FY23 (Apr-Feb). This was matched by a 10.3 per cent decline in imports, year-on-year. With the result, NER was a net exporter to the tune of 2,162 MU in FY23 (Apr-Feb) as against a much humbler 483 MU in FY22 (Apr-Feb).

 

• In FY23 (Apr-Feb), the biggest interregional electricity transfer, at 59,352 MU, took place from WR to NR. This accounted for around 28 per cent of the total interregional transfer. The next two important transfer regions were ER to SR and ER to NR.

 

• The busiest transmission corridor during FY23 (Apr-Oct) was the 765kV Angul-Srikakulam double-circuit line travelling from Odisha to Andhra Pradesh. This PGCIL-owned line was used almost entirely for exports from ER to SR, transferred around 15,536 MU in FY23 (Apr-Feb).
