Last month, the CFO of a textile giant in Gujarat sat with two proposals on his desk. On paper, the decision was a “no-brainer”:
- Solar PPA: ₹3.20/unit (The L1 Bid)
- Wind-Solar Hybrid PPA: ₹3.80/unit (The Winner)
A 60-paisa gap feels like a dealbreaker when you are consuming millions of units. But just before he signed the “cheaper” term sheet, he asked the one question that changed the trajectory of the deal: “Gaurav, am I missing something?”.
The Illusion of “Cheaper” Power
Most developers sell you a “price”. At InfiniaSolar, we advise on a “Grid-Hedge.” The reality for 24/7 manufacturing is that Cost per UNIT doesn’t matter nearly as much as Cost per YEAR.
When we audited the load profile for this facility, the “cheaper” option was actually the least efficient:
- The Solar Illusion (₹3.20): While the unit price is lower, it only replaces 20–30% of total power, primarily during the day.
- The Hybrid Reality (₹3.80): This solution replaces 50–70% of total power by covering both daytime and evening slots.
The Verdict: The Hybrid option replaces 2–3x more units. Even with a higher tariff, it delivered 75% higher total annual savings because it reduced the volume of expensive power purchased from the grid.
Targeting the “Money Peak”
Why does Hybrid win? Because it targets India’s costliest power slots. Grid power is often 3x more expensive during the evening peak (6 PM – 10 PM) when Solar is offline.
Solar is a daytime band-aid; Hybrid is a strategic cure for continuous loads. By wiping out high-cost evening units, the “expensive” tariff actually leads to a lower total electricity bill.
The Decision: Wealth vs. Tariff
The Board didn’t buy a tariff; they bought Net Wealth Creation over 15 years. They approved the Wind–Solar Hybrid PPA because they realized the cheapest tariff on a term sheet rarely results in the cheapest outcome for the P&L.
