Option	Fuel Needed	Monthly Cost	Monthly Savings	Annual Savings
Current (Diesel Only) Your current setup	3,600 L diesel/month 12,000 kWh × 0.3 L/kWh	₦3,960,000	-	-
Dual-Fuel Conversion Keep generator + add gas	2,160 L diesel + 1,608 L gas 40% diesel displacement	₦3,196,080	₦763,920 19% off	₦9,167,040
Pure Gas Generator New gas-only generator	4,020 L gas/month 12,000 kWh × 0.335 L/kWh	₦2,050,200	₦1,909,800 48% off	₦22,917,600

• Energy needed: 12,000 kWh/month

• Load-adjusted diesel consumption: 0.3 liters per kWh

• Total diesel: 3,600 liters × ₦1,100 = ₦3,960,000

• 40% diesel displacement with gas supplementation

• Remaining diesel: 2,160 L × ₦1,100 = ₦2,376,000

• Gas needed: 1,608 L × ₦510 = ₦820,080

• Gas replaces 4,800 kWh (40% of energy)

• Load-adjusted gas consumption: 0.335 liters per kWh

• Gas needed: 4,020 L × ₦510 = ₦2,050,200

• Based on real field data: LPG requires more volume but costs less

• Gas calculation includes vaporizer efficiency and liquid density

• Current setting: 50-75%

• Diesel efficiency: 0.3 L/kWh

• Gas efficiency: 0.335 L/kWh

Best cost savings typically achieved at 75-85% load

• Power factor: 0.8 (industry standard for generators)

• Fuel consumption based on verified engineer field data

• Dual-fuel displacement: 40% (conservative industry standard)

• LPG consumption calculated from kg/hr data with vaporizer efficiency

• Prices: Current Nigeria market rates (may vary by region)

LPG requires more volume per kWh than diesel but offers significant cost savings due to lower price per liter.
