Custom solutions for unique transmission challenges
-
Leidos brings over 70 years of new transmission line development and project management experience in support of both investor-owned and municipal utility growth goals. We use the latest technologies and sophisticated design tools to address varying project requirements – from simple to complex terrain, from basic to the latest FERC 1000 Extra High Voltage (EHV) pursuits, and from feasibility studies to final designs.
-
Aging infrastructure, changing load flows, system reliability requirements, and permitting challenges are all drivers in upgrading existing transmission line infrastructure to extend asset life and increase capacity. Leidos has broad experience in upgrading existing transmission lines for voltages from 69 kV to 345 kV.
-
Increasingly limited rights-of-way, congested city locations, reliability constraints, and aesthetic concerns can make it difficult for a utility to construct overhead lines. With underground transmission line experience in all phases – from concept to energization – Leidos provides the needed expertise when underground transmission is the solution.
-
In addition to design and engineering services for capital programs, Leidos also provides maintenance programs to help keep existing infrastructure in service and identify and implement timely replacement plans. Leidos’ expert staff provides field inspections of assets and condition assessments to prioritize replacements and/or model in structure conditions. We work with our clients to create system-wide plans to extend the useful life of assets, and develop capital plans for necessary replacements.
