Formation Temperature refers to how hot rocks and fluids are deep underground where geothermal energy is produced. Think of it like taking the temperature of the Earth at different depths. This measurement is crucial for finding good spots to build geothermal power plants because hotter temperatures mean more energy can be produced. When candidates mention this term, they're usually talking about their experience in measuring, analyzing, or working with these underground heat levels to determine if a location is suitable for geothermal energy production.
