Market touches a new high of 131 MUs in October

On 11th October, the Day-Ahead Market traded 131 MUs, highest ever on a single day since the inception of the exchange in the year 2008 with 625 participants on that day.

The spot power market at Indian Energy Exchange traded 2.8 BUs (billion kWh) in the month of October - about 10 per cent higher than 2.5 BUs traded in September and about 6 per cent higher as compared to volume traded at the exchange in the same month last year.

On 11th October, the Day-Ahead Market traded 131 MUs, highest ever on a single day since the inception of the exchange in the year 2008 with 625 participants on that day. At 4.5 BUs, the purchase bids far outstripped the sell bids at 3.8 BUs, clearly indicating that the market remained a seller´s market through the month. The increased demand could largely be attributed to legislative elections in a few States as well as the festive season.

The Average Market Clearing Price in October was Rs 4.17 per unit - almost at par with the price in the previous month even though the demand saw an increase of about 8 per cent this month. In terms of price for the bid-areas, almost 10 per cent decline in the Average Area Clearing Price (ACP) was seen across all bid areas while in the southern States, the area price increased by almost 50-70 per cent due to transmission congestion.

In terms of overall impact of congestion on the Inter-State Transmission System (ISTS), almost 286 MUs were constrained due to unavailability of transmission corridor as compared to only 42 MUs lost in September 14. Persistent transmission congestion towards the southern region and between the southern States is a key reason for increased price of electricity in the South.

In the Northern, Western, North-Eastern region and Punjab, the ACP was Rs 3.66 per unit, almost 10 per cent less over September. The ACP in States of Andhra Pradesh and Karnataka was at Rs 6.69/unit and the ACP in Tamil Nadu and Kerala was at Rs. 8.15/unit. The ACP in the southern States was higher than ACP in other States primarily due to congestion in inter-regional corridors towards South.


  • A total of around 2.8 BUs were traded in October. A few key highlights of the month were:
  • The western States bought 1.3 BUs - almost 80 per cent more power over the previous month. With Chhattisgarh being a part of the region where large generation capacities are located, the region largely remained a net seller.
  • Maharashtra was a constant buyer, purchasing about 24 MUs on a daily average basis.
  • The northern and southern States along with Punjab were net buyers.
  • The eastern and the north-eastern regions were net sellers of electricity.

647 participants traded in the spot market on an average daily basis in October with the highest participation of 791 participants on 31 October, 2014.
