E3 Consulting has significant transmission consulting experience, having completed over 40 consulting assignments representing several thousand miles of new transmission lines ranging from less than one mile to more than 400 miles. Our experience includes interconnection, overhead, underground and submarine lines, with voltage ratings as high as 500 kV, and includes HVDC transmission cables and converter stations. We have completed assignments that involved the analysis of a client’s entire transmission network, as well as all aspects associated with the planning, design, permitting, construction, operation, maintenance, loss allocation, revenue recovery assurance, reliability, economics, and financing of a transmission line or transmission system. E3 has worked on a variety of noteworthy transmission projects including the one of the largest financed domestic transmission projects, a cross-border project, and several that were selected as Deal of the Year recipients from Project Finance Magazine.

Sharyland CREZ Transmission Project, TX

E3 provides independent engineering services for complex transmission project

E3 served as the Independent Engineer to the lenders for the Sharyland Competitive Renewable Energy Zone (CREZ) Transmission Project. The Public Utility Commission of Texas (PUCT) designated Sharyland Utilities to construct the new lines and substations as part of its award for the CREZ projects. The Sharyland CREZ Project was comprised of five 345kV transmission line segments and four substations located in the Panhandle region of Texas as part of a statewide effort to allow the development of large scale wind generation and provide transport of the output thereof to the large load centers of the state. The Project’s transmission facilities will earn a regulated rate of return under tariff provisions of the Public Utility Commission of Texas (PUCT). The five transmission line segments total 428 circuit miles over 295 miles of ROW. E3 also provided construction monitoring of the transmission facilities on behalf of project lenders.

Antelope-Elk Energy Center Line, TX

E3 served as a technical advisor on new transmission

E3 served as the independent engineer for the Sharyland Utilities 345 kV transmission line that connects the Antelope-Elk Energy Center in Hale County, Texas, to the new White River substation in Floyd County, Texas. The line is owned by Golden Spread Electric Cooperative, and is approximately 51-mile long, running through the Panhandle of Texas. The Project is 100% regulated by the PUCT and receives revenues via a regulated rate base regime. The debt financing consisted of a construction and term-loan facility, with closing at the end of Q1 2015. Construction was completed in April, a month earlier than scheduled.

Trans Bay Cable Project, CA

E3 provided independent engineering services for submarine transmission system

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. The cable connects the Pacific Gas & Electric (PG&E) Pittsburg Substation, which has excess electrical capacity, to a load pocket at PG&E’s Potrero Station in San Francisco. E3 provided a technical due diligence review in support of financing the development and construction of the Project on behalf of Bayerische Landesbank. 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.
