What MMR Group does

MMR Group, Inc. is the largest open-shop electrical and instrumentation contractor in the United States, founded in 1991 by James "Pepper" Rutland and headquartered in Baton Rouge, Louisiana. The company delivers electrical construction, instrumentation installation, telecommunications and security systems, commissioning and start-up, maintenance, modular fabrication, and distributed power generation services to enterprise clients across oil & gas (upstream, midstream, downstream), chemical and petrochemical, power generation, industrial manufacturing, and mission critical / data center sectors. Core technical assets include a 200,000-square-foot Modular Systems facility in Lafayette, Louisiana for data center skid assembly (backed by a $55.2 million investment), UL 508A certified panel fabrication capabilities across 40,000 square feet, in-house engineering for power systems from 480V to 500kV, and MMR Power Solutions' cogeneration/microgrid/CHP/solar PV/energy storage offerings with 10 onsite power projects totaling 23MW.

MMR generates revenue primarily through project-based construction contracts recognized on a percentage-of-completion basis, with multi-year contract values spanning millions to over $320 million (e.g., Sasol Lake Charles). Secondary revenue streams include prefabricated modular hardware sales, Energy Services Agreement (ESA) structures under which MMR owns and operates on-site generation assets and charges clients fixed or escalating energy prices, and ongoing maintenance and professional services contracts. The company has scaled to $2.33 billion in 2024 revenue (a 67% year-over-year increase) with 5,000+ employees across 30 offices, reaching 1.5GW of mission critical capacity and executing projects across 36 countries on four continents. GTM is exclusively direct enterprise sales through competitive bidding and negotiation with general contractors and project owners on mega-projects such as LNG facilities, petrochemical plants, data centers, and power generation infrastructure.
