Which code does this activity belong in?
Geothermal electric power generation establishments operate facilities that convert heat energy derived from the Earth into electricity for transmission and distribution systems. This code distinguishes geothermal operations from those using hydroelectric power, fossil fuels, nuclear power, solar energy, wind power, or biomass. The defining characteristic is the use of subsurface heat as the energy source for electric generation, setting it apart from all other renewable and conventional power generation methods.
