How much power is in a flare?
A whiteboard estimate of the electricity hiding in flared gas: one million standard cubic feet a day is roughly 4 to 5 MW from a gas engine.

Short, sourced explainers from the field: flare gas, gas to power, and the common mistakes that cost modular energy projects.
A whiteboard estimate of the electricity hiding in flared gas: one million standard cubic feet a day is roughly 4 to 5 MW from a gas engine.
Associated gas rate is oil rate times gas-oil ratio, and the product is usually a hump. Why a plant sized to day-one gas flares or idles.
Some remote oilfields truck in diesel for power while their own gas burns in a flare. What that costs in CO2 and in money.
Gas engines and turbines lose output in heat. Why plants in hot climates must be sized on the site-rated curve, not the ISO rating.
Installing exactly as many gas engines as the load needs looks efficient. The availability arithmetic says otherwise.
A gas engine turns roughly 28 to just over 40% of its fuel into electricity. Recovering the heat lifts total efficiency to about 80%.
