How many GJ of natural gas to power 1 MW plant?
The energy content of natural gas is approximately 34.27 GJ per 1000 cubic meters CH4. A 1 MW (1000 kW) power plant operating at 35% thermal efficiency would require approximately 3.54 m3 of natural gas per hour. Therefore, the natural gas requirement for the power plant would be approximately 3.54 * 34.27/35 = 3.71 GJ/h.
