Harnessing the Power of Nature

Since the 1990s, MJE has included renewable energy as part of our broad range of electrical construction services. MJE has the breadth of experience to serve its customers in every phase of a project, no matter how large or complex, even in remote environments. We have demonstrated our ability to perform construction for general contractors, owners, and developers. MJE has acquired a deep understanding of the complexities inherent to any renewable energy project and is able to complete these projects on time and on budget.

Our skilled project management and knowledgeable field craft allow us to understand the critical components specific to renewable energy projects. We keep abreast of current technologies and techniques, ensuring that we implement the most up-to-date construction methods. As a result, our crews have achieved extraordinary project performance, attaining levels of safety and quality that surpass industry standards. With this expertise, we are able to meet any unique challenges with innovative solutions and deliver a project that exceeds our customer’s expectations.

A key market within our portfolio of renewable energy services is wind power generation. Electrical construction for wind farms requires a team with knowledge in the entire scope of an installation, from foundations through to generated energy storage. This experience makes us uniquely capable to achieve success on every project.

M. J. Electric, with our comprehensive services offering, provides our customers with a single-source electrical contractor. Some of the renewable energy services we provide include:


•   Collector Substation & Interconnection Switchyards

The increase in renewable energy production triggered the need to regulate the introduction of power into the grid. Battery energy storage is bringing enhanced reliability to the grid by sustaining power during fluctuating energy production by renewable sources, such as wind power. This emerging technology is a cost-effective and cutting-edge solution to secure supply and modernize our infrastructure. MJE is at the forefront of this quickly evolving renewable market. We have demonstrated expertise in project management and complete our projects on time, efficiently, and most importantly, safely. From interconnection to the grid through completing the testing and start-up activities, MJE works with our customers to meet their battery storage construction needs.

M. J. Electric’s experience and success as either an EPC lead or EPC partner differentiates us from our competition. MJE has developed a strong model to deliver a full turnkey electrical package that includes the downfeed from the generator to the collector substation and transmission line(s). The ability to control and coordinate the engineering and procurement are key success factors to deliver a timely and cost effective construction project. MJE has partnered with many different engineering firms and has established strategic relationships with the suppliers and vendors in the industry. As a result, we have the right contacts to select the best partners to match the needs of a specific project.
