PPAC & BEE Cooking Energy Disclosure:
  • Induction cooktop efficiency (85%) follows BEE Schedule 20 and IS 16102 standard baselines.
  • PNG energy content (38.5 MJ/SCM) and LPG net calorific value (46.1 MJ/kg) follow PPAC conversion standards.
  • Relative cost rankings depend heavily on local electricity slab tariffs versus LPG cylinder refill subsidies.

How Cooking Fuel Costs are Normalized & Calculated

Cooking fuel comparisons require normalizing gross energy into useful delivered heat (kWh) based on burner efficiency: Induction (85%), PNG (62%), and LPG (58%).

Useful Heat (60 kWh/mo 4-Person Family) = Delivered Thermal Energy
Induction: 60 kWh ÷ 0.85 = 70.59 kWh Electricity (₹529.41/mo @ ₹7.50/unit)
PNG Piped Gas: 60 kWh ÷ 6.634 kWh/SCM = 9.04 SCM Gas (₹438.44/mo @ ₹48.50/SCM)
14.2 kg LPG Cylinder: 60 kWh ÷ 105.42 kWh/Cyl = 0.569 Cylinders (₹483.65/mo @ ₹850/Cylinder)
