Electric Motors For Line 200 & Line 300 Project In Louisiana

Driftwood Pipeline LLC (DWPL) has received a favorable final environmental impact statement from the Federal Energy Regulatory Commission (FERC), allowing its Line 200 and Line 300 project to move forward. The project involves the construction of dual 42-in. (1-m) natural gas pipelines (Line 200 and Line 300) and an approximately 211,200-hp (157,555-kW) electric compressor station and appurtenant facilities, to be located in Beauregard and Calcasieu Parishes, Louisiana. When completed, the project will have a nominal capacity of 4.6 Bscf/d (130 × 106 m3/d). The purpose of the project is to provide enhanced supply access to the natural gas market in the Lake Charles, Louisiana, area and support the growing liquefied natural gas (LNG) markets in and around the Lake Charles region in Calcasieu Parish.

DWPL proposes to construct and operate the Indian Bayou Compressor Station approximately 6 miles (9.7 km) south of Ragley, Louisiana. The Indian Bayou Compressor Station will be powered by electricity from the existing power grid and use four electric motor compressor packages with a combined power of 211,200 hp. DWPL chose electric-driven compression to reduce the project’s long-term emissions by approximately 99.3% compared to gas-fired turbines.

The electric motors and compression will be installed in a phased approach, as Line 200 and Line 300 will be constructed in two phases. Construction for Phase I includes the entirety of Line 200 (approximately 36.9 miles [59 km]); the Indian Bayou Compressor Station, including three electric-driven motors with a total of 158,400 hp (118,166 kW) of compression; up to 12 meter stations/interconnect facilities; and pig launcher and receiver and other appurtenant facilities associated with Line 200. Construction for Phase II includes Line 300 in its entirety (approximately 30.8 miles [50 km]), one additional electric motor-driven compressor at the Indian Bayou Compressor Station to provide an additional 52,800 hp (39,389 kW) of compression, and pig launcher and receiver and other appurtenant facilities associated with Line 300.
