A delayed Diwali this year brings some respite to National Load Despatch Centre (NLDC), as no sudden spurt on electricity demand is expected this Diwali season (Monday and Tuesday).

This is primarily for two reasons, sources say. First this year Diwali is delayed and already peak agricultural demand is over. Second, a large number of industrial units are shut for the festival, which drastically brings down the demand.

In fact, according to power producers, the Northern Regional Grid experiences relatively high demand during July-August (paddy season) which was being partly met from generation in the other two regional systems, as intended through the inter-regional transmission system built for the purpose.

“Peak demand may not be much. But ramping is important. NLDC is monitoring the flow and no disruption is expected,” a senior official at NLDC told Business Line.

Ramping is expected to go up on Monday and Tuesday in the Northern and Western grid. This means electricity consumption would suddenly go up after dark.

On Monday, the Northern region saw peak hour demand of around 32,051 MW. The region is under peak shortage of about 2,749 MW.

The highest peak hour demand is seen in the Western grid of 38,028 MW with peak shortage of 549 MW.

On the other hand, peak demand in the Eastern grid is 13,554 MW, North-Eastern grid is 1,754 MW and Southern grid is 24,230 MW.

In July, almost half of India blacked out with the Northern, Eastern and North-Eastern grids collapsing, affecting 20 States.
