Western Region accounts for over half of electricity transfer in FY21

The Western Region (WR) of the National Grid accounted for over half of the interregional electricity exchange in FY21. This is amongst the key finding of a special study by T&D India, based on official statistics released by Power System Operation Corporation Ltd (POSOCO).

 

 

The following are some highlights of the study:

 

 

 

 

 

 

 

 

Exchange versus Generation

In FY21, total electricity generation, from both conventional and renewable energy sources, stood at around 1,381 BU, based on statistics released by Central Electricity Authority (CEA). In FY21, the total interregional electricity exchange was 215 BU. This means that the quantum of interregional exchange was around 15.5 per cent of the total electricity generation.

This proportion will increase as and when new interregional power transmission capacity gets added. As of December 31, 2020, India’s total interregional power transmission capacity stood at around 104,223 mw (or 104 GW), nearly 85 per cent of which was owned by Power Grid Corporation of India Ltd (PGCIL). For a frame of reference, India’s total power generation capacity currently stands at around 382 GW. The ratio of interregional transfer capacity to total generation capacity therefore stands at 27 per cent. In other words, around one-fourth of India’s power generation capacity is available for interregional transfer. This is of course speaking at the broad national level, actual transfer between two specific regions depends on the transfer capacity available between the regions.

By end of FY21, India’s total interregional transfer capacity, which is the capacity of the National Grid, is expected to reach 118 GW.

 

Note: MU = million units = million kwh; BU = billion units = billion kwh = 1,000 MU
