  • 4 kW grid-tie hydroelectric system (no batteries)
  • 165 feet of net head
  • 250 gpm

The system was designed to offset the energy use at a toll road booth and administration building. The turbine and generator are located in a locked underground vault, which eliminates the need to heat and cool the room as well as protect from vandalism as the vault is located in a remote area. The turbine and generator are located 2,200 feet from the point of use. Wild unregulated, 400 volt, 3-phase power is transmitted from the generator through the control and inverter system where it is converted to 3-phase, 208 volt, regulated power which is then backfeed through a net meter to the toll both facility.
