Swapp Stations give India's grid a new way to absorb solar power, right where it spikes.

As India shifts from coal to solar, the shape of daily power demand has changed. Coal plants could ramp up and down slowly, matched to demand. Solar cannot. It floods the grid at midday and disappears by evening, creating what grid planners call the duck curve, a shape where midday supply outpaces what the grid can use, and evening demand outpaces what solar can supply. When midday supply outruns what the grid can take, that power gets held back.

Swapp Stations sit outside this problem. Spread across a city instead of concentrated at one plant, each station can absorb solar power the moment it spikes, no new transmission lines needed. This is the distributed solar absorber argument in more depth.

Here are some facts:

In just 6 months of 2025, India held back 2.3 TWh of solar power, worth ₹690 crore, enough to power 55,000 buses for a year. That is the scale of power Swapp Stations are built to catch.
