WHITE PAPER : Project Solar Cooker
A National Mandate for Energy Sovereignty
1. The Current Crisis Context ( March 2026 )
India currently faces a critical LPG supply shortage triggered by West Asia
geopolitical tensions. With 33 crore (330 million) LPG connections, India’s
dependence on imports (currently ~60%) has created a "panic atmosphere." As
highlighted in my advocacy (2018–2026), the failure to diversify into solar
cooking at scale is now a national security vulnerability.
2. Evaluation of Past Suggestions & Implementation Gap
My Core Suggestions ( 2018 - 2026 ) | Relevant Blog/Reference | Current Status (March 2026) |
Mass conversion of 10% LPG users | "Making Best of Bad Bargain" | NOT IMPLEMENTED. Only ~0.08% conversion achieved. |
Indoor Solar Chulha (IIT-B Design) | ONGC Competition 2018 | ABANDONED -by ONGC; adopted as niche pilot in MP. |
50% Direct Purchase Subsidy | "Averting the LPG Panic" | PARTIALLY ADOPTED via Carbon Credits, but lacks "War Footing" funding. |
Standardized Solar Cooker Network | "Solar Cooker Network" | FRAGMENTED. Left to private players like Stove Kraft/Prestige. |
3. The Economic Logic: Investment vs. Savings
To achieve your goal of converting 3.3 crore (10%) of LPG users to Solar:
The Investment:
Total Expenditure: 3.3 Crore units × ₹ 9,000 = ₹ 29,700 Crore.
Average Solar Cooker cost is ₹18,000. A 50% Subsidy requires ₹9,000 per
unit.
The Savings:
LPG Import Savings: 231 million cylinders/year. At an import cost of
~$ 12 / cylinder, this is ~$ 2.7 Billion (₹ 23,000 Crore) annually.
Every solar cooker saves ~7 LPG cylinders/year.
Breakeven:
The government recovers the entire subsidy cost in just 1.3 years through
reduced forex outflow and LPG subsidy savings.
The Economic Ledger: Total System Savings
By replacing one LPG cylinder with Solar, the government doesn't just save the gas; it saves an entire subsidised infrastructure.
Cost Component (Per 14.2kg Cylinder) | Est. Value (2026) | Impact of 33M User Transition |
Import Cost (CFR) | $12 (~₹1,000) | ₹23,100 Crore (Direct Forex Saved) |
Targeted Subsidy (PMUY) | ₹300 | ₹6,930 Crore (Budgetary Savings) |
Logistics & Delivery | ₹150 | ₹3,465 Crore (Fuel & Transport Savings) |
OMC Under-recovery (Loss) | ₹150 | ₹3,465 Crore (Corporate Debt Reduction) |
TOTAL ANNUAL SYSTEM SAVING | ~ ₹ 1,600 | ~₹ 37,000 Crore TOTAL SAVINGS |
Conclusion:
A 50% subsidy for a solar cooker pays for itself in less than 10 months when accounting for
the total cost of the LPG ecosystem.

The War-Footing Implementation Strategy
To convert 33 million households, the government must move from "pilot trials" to
"industrial scale."
Manufacturing: I
Invoke the PLI (Production Linked Incentive) scheme for Thermal Batteries
and Solar Hybrid Induction plates.
Pricing:
Base unit cost ₹18,000. Govt provides ₹ 9,000 (50%) Direct Subsidy.
Total Mission Investment: ₹ 29,700 Crore (One-time).
Net Return on Investment:
After the first year, the government realizes a surplus of ~₹ 7,000 Crore
annually compared to the current LPG subsidy drain.
