Transmissions and Distributions

JMG has worked closely with utility-owned, investor-owned and independent power producers to identify, design and implement transmission projects of various sizes and complexity. From renewable to traditional electric transmission.


JMG has constructed hundreds of high-voltage substations, switch stations and interconnect stations nationwide, and is skilled in performing substation work under engineer-procure-construct (EPC) methods of project delivery. In addition to construction, we offer complete turnkey services including project management support, material procurement and management, quality assurance/quality control, certified bus welders, testing/commissioning and final job close-out.



JMG installs new overhead and underground distribution systems at low- and medium-voltage, connects existing distribution to new power sources, and provides operations and maintenance to the entire network.
A customized routine preventive maintenance plan is developed for each distribution system in accordance with utility industry standards and manufacturer requirements. Our highly trained and certified personnel provides immediate response to any outages that occur on our distribution systems.
