Our Clients

EHV Power has worked on high voltage underground transmission cable systems for electrical utilities, independent power producers and developers across North America as well as in international markets.

We know that each customer has unique requirements that cannot be satisfied with typical or off-the-shelf solutions. That is why we provide custom services. We form partnerships with our customers to leverage their knowledge of their own environment with our specialized high voltage cable knowledge, experience and equipment to create an individualized solution that works.
