Power Delivery

M. J. Electric excels in the skills required to provide construction services on the power grid and has demonstrated that ability by completing a wide range of projects nationwide. In addition to traditional methods, we have access to specialized techniques and technologies, such as energized services, to complete projects more efficiently, safely, and cost-effectively.



After constructing thousands of miles of transmission lines, we understand what it takes to make a project successful. That experience allows us to find innovative approaches and provide planning and cost-effective solutions to complex transmission projects. We have developed long-term strategic relationships with our customers to provide added value to their portfolio of work.

We have installed and maintained of all sizes and types of transmission lines in even the most challenging terrains and circumstances. With specialized equipment, state-of-the-art technology, and energized services, we offer solutions to address the unique needs of utilities.

  • Overhead & Underground
  • Line Relocations
  • Reconductoring
  • Pole & Tower Erection
  • OPGW Installation
  • Energized Services


We construct and maintain overhead and underground distribution systems for electric utilities, municipalities, and cooperatives. Considerable planning is necessary to manage distribution systems in terms of safety, operation, budget, environmental concerns, and coordination with government agencies. Even when working in critical outages or constrained schedules, we provide safe, quality construction delivered on time and within budget.

The need for fewer interruptions in service require specialized equipment and innovative techniques. Our state-of-the-art equipment allows work on distribution systems with no interruption to power delivery. We also have the expertise to help utilities successfully convert from a standard distribution grid to a smart grid for enhanced power delivery.

We can maintain, upgrade, or rebuild virtually any voltage line – without interrupting the flow of power to consumers. All types of repairs and maintenance, including structure change outs, reconductoring, emergency repairs, and equipment replacement can be performed with the line energized avoiding the issue of congestion and taking the facility off-line.

During energized conditions, we use established hot stick and barehand energized techniques and the proprietary LineMasterTM Robotic Arm. This cutting-edge technology provides significant advantages for worker safety and efficiency as well as value for customers with a critical dependency on a single flow path.

Personnel safety is paramount. Our position as a subsidiary of Quanta Services is a key differentiator in safely providing energized services. Our energized crews receive extensive specialized training and oversight from Quanta’s Energized Service Group to ensure we deploy the most effective tools and procedures in the industry.
