You don't run 170 amps of 240v nearly 1/2 a mile. You would be talking extremely large conductors and multiple conductors per phase to limit voltage drop.
You need a different solution. A new service close to the location, a step-up and step down transformer solution, diesel power generator, diesel mechanical power in place of the electric motor, etc.
