Two types of production well pumps are used in geothermal power plants: lineshaft and submersible. A lineshaft pump has a motor at the surface connected to a downhole mechanical pump with several hundred meters of shaft. A submersible pump is a combined electric motor and mechanical pump submerged in a well with electric wires running to the surface. Each pump has tradeoffs when compared to the other, for instance: lineshaft pumps are cheaper and last longer, while submersible pumps have higher efficiency (DiPippo, 2015). GETEM only provides costs for lineshaft pumps, so we only consider lineshaft pump cost in genGEO.
