Demonstration Site – Pahrump, NV
ARES Nevada is developing a 5MW GravityLineTM energy storage facility on approximately 20 acres at Gamebird Pit, a working gravel mine in Pahrump, Nevada. This project employs a fleet of mass cars, with each set weighing 720,000 pounds.
When charging (known as ‘Regulation Down’ or ‘Reg Down’), ARES mass cars will draw electricity from the grid which powers their drive motors to move the mass cars uphill against the force of gravity — efficiently converting electrical energy into gravitational potential energy. When the grid requires energy (‘Reg Up’), this process is reversed, and the mass cars proceed slowly downhill with their motors operating as generators, converting the potential energy of the mass cars’ elevation back into electricity in a highly efficient 15-minute round-trip process.
