Fervo engineers for thermal drawdown up front, it is well known that for EGS to maintain constant power output you need to periodically re-stimulate the field after a period of some number of years. What matters for the economics is the rate of eventual drawdown. The nameplate 100MW is also a bit misleading as it represents gross power output without taking into account the parasitic load of pumping which for an EGS plant is quite high. There was a ~60% parasitic load for their test facility and IIRC Fervo is eventually targeting 30-40% for the commercial power plant.
