A wellhead pressure reduction and power generating assembly includes a wellhead, a supply pipe, a prime mover, a pump, and an accumulator bank. The wellhead is configured to supply a pressurized production fluid flow and is in fluid communication with the supply pipe. The prime mover is configured to induce a pressure drop within the pressurized production fluid flow and is in fluid communication with the supply pipe. The pump is configured to receive a mechanical force of the prime mover and operatively coupled with the prime mover. The accumulator bank is configured to accumulate a pressurized hydraulic fluid and is in fluid communication with the pump.
