Electric Transmission

Transmission developers face a complex challenge: No matter how urgently new transmission is needed to improve reliability, connect renewable energy, or upgrade aging infrastructure, most projects will face significant public opposition. To successfully site new transmission lines, E & E’s planners and public consultation specialists are collaborating with project developers and engineers to engage the public and secure regulatory approvals on projects from coast to coast. 

From underwater and underground DC lines to urban rebuilds and renewable generation interconnections, E & E can meet any transmission need you may have. At E & E, our comprehensive approach to transmission project siting and permitting incorporates over 40 years of linear energy project experience. Using our proprietary routing tools, we define potential transmission corridors and their environmental features and create a permitting roadmap. Armed with this information, we schedule introductory meetings with key stakeholders and agencies to further identify environmental constraints, community concerns, and permitting requirements early. Using an iterative process, our team develops strategies to resolve issues and quickly move projects from concept to reality.
