"Around 20-25 per cent hike in the demand of inverters, their batteries and generators is expected in the current summer, particularly in NCR in the wake of anticipated scorching heat," the industry body said in a statement.
The inverter market in the region was at Rs 2000 crore (Rs 20 billion) last year and is estimated at Rs 2500 crore (Rs 25 billion) this summer, Assocham Secretary General D S Rawat said.
The worst affected sectors are industrial and residential areas, hospitals, schools and shopping centres where power cuts could range between 10-12 hours a day because of demand supply mismatch, it said.
Of the total market, around 40 per cent market is organised and large players like Su-Kam, Microtech and Luminous are likely to face tough competition from the unorganised segment, the statement said.
The chamber analysis shows that, last summer peak power demand in NCR was about 4600 MW which might grow to over 5800 in the current season.
The generator market size in NCR was less than Rs 5000 crore (Rs 50 billion) during last summer, most of which was in the industrial, shopping centres and agriculture segment and would grow at least by over Rs 1000 crore (Rs 10 billion).
The Rs 3200 crore (Rs 32 billion) domestic AC segment has been growing at 19-20 per cent annually, which will rise to 25 per cent in 2008.
