Morrison Completes Expansion at Leaf River Energy Center

The Leaf River Expansion was successfully completed by Morrison’s Onshore Construction Division, which installed a compressor booster station at New Jersey Resources Leaf River Energy Center in Southeastern Mississippi. This strategic project involved significant civil, structural, and mechanical installations to enhance the facility’s capacity, improve operational efficiency, and support long-term energy production goals. It also strengthened the facility’s ability to meet future demand and maintain uninterrupted operations.

As part of the Leaf River Expansion, the project included the clearing and grading of 4.5 acres of land, creating a solid foundation with over 550 cubic yards of concrete to support the installation of new major equipment. Morrison also successfully installed numerous critical components, such as a 5000 hp centrifugal compressor skid and matching electric motor, gas coolers, suction scrubbers, air compressors, generators, and lube oil coolers. These upgrades enable the facility to operate more reliably, handle increased throughput, and maintain strict environmental and safety standards.

Other notable aspects of the project include:

• Comprehensive piping systems both above and underground
• Two major mainline tie-ins to existing infrastructure
• Complete compressor building installation
• Construction of portable control room (PCR) housing MCC, VFD, switchgear, and UPS systems
• Full instrumentation and electrical integration
• Complete painting, coating, and insulation

The Leaf River Expansion project scope included installation of all manual, actuated, and control valves throughout the system in addition to specialized equipment such as blowdown silencers, sump tanks and pumps, and oily water management systems.

Morrison’s experienced crews successfully navigated complex system integration requirements, leveraging advanced project management techniques and technical expertise. Their dedication to quality, safety, reliability, and precision reinforces Morrison’s reputation for excellence in energy infrastructure construction and highlights the company’s ability to deliver safe, efficient, and high-quality results on large-scale industrial projects, even under challenging conditions.
