The total volume of interregional electricity transfer during the first seven months (April to October) of FY23 grew marginally by 1.9 per cent, on a year-on-year basis.
The total quantum of electricity transfer stood at 138,023 million kwh (million units, MU) in the April-October period of FY23 as against 135,396 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). The five 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.
- WR was less of a net exporter in FY23 as compared with the previous year. This was due to sharp 22.5 per cent rise in imports, compounded by a 9.1 per cent decline in exports. Net exports by WR fell to 28,787 MU in FY23 (Apr-Oct) from 41,001 MU in FY22 (Apr-Oct).
- SR witnessed a small rise of 4.3 per cent in imports. However, exports grew by a massive 41.3 per cent during FY23 (Apr-Oct). Due to this, SR was less of a net importer in FY23. In the April-October period of FY23, net imports by SR fell to 16,344 MU from 19,470 MU in the corresponding period of FY22.
- ER more or less maintained its net export level in FY23 (Apr-Oct), at 32,149 MU, as against 31,267 MU in FY22 (Apr-Oct).
- NER saw a big improvement its net export level. Exports from NER to other regions grew by 38.5 per cent to reach 3,605 MU in FY23 (Apr-Oct). This was matched by a 26.9 per cent decline in imports, year-on-year. With the result, NER was a net exporter to the tune of 1,984 MU in FY23 (Apr-Oct) as against a much humbler 386 MU in FY22 (Apr-Oct).
- 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, used almost entirely for exports from ER to SR, transferred around 9,151 MU in FY23 (Apr-Oct).
