| Abstract | Adding to its existing generating capacity of 27 MW, Ormat’s Puna Geothermal Venture (PGV) geothermal power plant recently completed a successful 8MW expansion project bringing more renewable, low-cost electricity to the people of Hawaii. The project presented several technical challenges including use of high scale potential brine in a state-of-the-art binary plant, development of highly reliable brine pH monitoring and control system, and brine injection management in a high energy resource. Each of the project challenges were overcome with unique engineering solutions. |
