Gas-to-power calculator
MMSCFD to MW Gas-to-Power Calculator.
Estimate how much electrical power a natural gas or associated gas stream can support before FEED. Designed for oilfields, flare gas projects, pipeline-gas IPP/PPA projects and modular power plants below 50MW.
Estimated net output
4.39 MW
Annual energy: 35,120 MWh/year
Conceptual N+1 blocks: 5 x 1.2MW class
How to read the result
Use it as a screening range, not a guarantee.
Gas-to-power sizing changes with gas quality and operating philosophy. This calculator uses the heating value and engine efficiency you enter, then subtracts a station loss or derating allowance for auxiliaries and site conditions.
Rule of thumb: 1 MMSCFD at 950-1,000 BTU/scf and 38-42% engine efficiency often lands around 4.0-4.7MW net after station loss. Associated gas with higher CO2, water, unstable pressure or lower LHV should be checked carefully.
Data CIMC needs next
- Gas composition and heating value.
- Pressure range and expected fluctuation.
- H2S, CO2, water and condensate risk.
- Target net output, voltage and load profile.
- Site ambient condition and operating mode.
Next step
Move from gas quantity to project route.
The calculator tells you whether the gas stream is worth deeper engineering. CIMC can then define gas conditioning, modular power blocks, 11kV interface, PMS/SCADA and remote monitoring.
