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.

Trans Bay Cable Project – E3 provided a technical due diligence review in support of financing the development and construction of the Trans Bay Cable Project on behalf of Bayerische Landesbank.  Trans Bay Cable is a 400 MW HVDC transmission system using underground and marine power cables to bring power to the City of San Francisco. After construction was completed, E3 provided a report to Barclays Capital to support the long-term financing of the Project. E3’s report addressed the engineering, commercial, and environmental aspects of the 54-mile HVDC cable project. The Project utilized Siemens inverter technology and Prysmian XPLE cables.  E3 also monitored the performance of construction and testing of the cable, on behalf of the lenders. The Project was named the 2007 North American Infrastructure Deal of the Year by Project Finance Magazine.

Bayonne Energy Center and HVAC Submarine Transmission Link – E3 prepared a comprehensive independent engineering report to support the financing of the Bayonne Energy Center in Bayonne, NJ. The 512 MW generating station includes a dedicated 6-mile long 345 KV AC submarine cable linking the generating plant in New Jersey (PJM) with New York City (NYISO). E3 reviewed permitting requirements, reliability, installation and interconnection arrangements and capital cost estimates for the new submarine cable link. The Project was named the 2010 North American Single Asset Project Deal of the Year, Project Finance Magazine
