Antelope-Elk Energy Center Line, TX
E3 served as a technical advisor on new transmission project
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 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.
