India Wasted 11 Billion Solar Units in 15 Months. Factories Have the Same Gap

India wasted about 11 billion units of solar in 15 months. It is the same country that runs short of power at eight in the evening. The Associated Press (AP) reported on why this week, and Ingro Energy was glad to be part of the story.

Solar peaks at noon, demand peaks after sunset

The reason is not complicated. Solar generation peaks at noon; demand peaks after sunset. Bridging the two needs either a wire or a battery, and a wire takes three years to build.

The same problem sits inside almost every factory

What is striking is that the grid's problem is repeated at the scale of a single site. Almost every factory in India has rooftop generation at noon, plant load at seven in the evening, and an electricity bill that reflects the difference.

Storage fixes that mismatch on site, and it does so without the constraints that slow grid-scale solutions:

• no land
• no evacuation approval
• no corridor

The real blocker is the analysis, not money or hardware

The blocker is not money or hardware. It is that finding out whether a battery pays on your site typically takes weeks, and returns one answer for one tariff slab.

Ingro Sims does it in an afternoon:

• twelve monthly bills in;
• your DISCOM's Time-of-Day tariff pre-loaded;
• 3,171 configurations simulated;
• a P90–P50 IRR band rather than a single number.

The country-level curtailment story and the factory-level bill are the same problem. On site, the fix is available now, and the first step is knowing whether it pays for your load and tariff. Ingro Sims is available at sims.ingroenergy.com.
