Geothermal Market Outlook - Energy Transition Report (condensed version)
Geothermal power generation initiatives are usually established in locations with high thermal gradients. On average, these projects hit reservoir temperatures of 210 degrees Celsius (°C), with many projects also having crossed the 300 degrees Celsius (°C) line. In such regions, operators typically drill deeper wells (on average 2 kilometer deep) to access the higher reservoir temperatures. Typically, these projects are located in areas where there is significant tectonic and volcanic activity, leading to the creation of high enthalpy regions.
