Electric Transmission

E3's transmission experience encompasses the entire project life cycle of new and existing transmission lines, including planning, pre-finance, finance, construction, performance testing, and operations and maintenance phases. E3 personnel have 35 years average of experience in generation and transmission planning for utilities, control area design, system operations experience, and consulting for international clients and cogeneration assignments. We have completed over 25 transmission consulting assignments, which have included more than 1,500 miles of new transmission projects ranging from less than one mile to more than 350 miles.

We have worked on elevated, buried, and submerged lines with voltage ratings below and above 500kV, and AC/DC transmission and conversion. Our assignments have ranged from those involving the analysis of a client's entire transmission network to those associated with the planning, design, construction, operation, reliability and economics of a transmission system. E3 has also assisted our clients on more than 2,000 miles of transmission line corridor environmental permitting.

Buried:
Fire Island Wind: E3 served as the independent engineer supporting the construction and term-loan financing for the 17.8 MW wind farm located on an island near Anchorage, Alaska. The Project was responsible for constructing two 34.5 kV transmission lines from the Substation to the Project Switching Station on Fire Island. E3’s services included a review of technology, status of land acquisition and permitting, construction contracts, construction costs and schedule, and logistics, among other items.  E3 also provided construction monitoring services for the Project.

Astoria I: E3 served as the independent engineer for the Astoria Energy Project in Astoria, New York. The project was electrically interconnected to Con Ed’s Astoria East Substation, which was located approximately 2,600 feet from the Site, necessitating the construction of a new double circuit 138kV transmission line that travels both above and below ground from the Site to the substation. E3 also provided construction monitoring services for the Project.
