Making Critical Design Decisions
Spanning a two-mile-wide river with a 230-kV transmission line is an inherently complicated feat that requires thorough consideration of all options. Before work began, Century prepared conceptual design documents for submarine cable installation, horizontal directional drilled (HDD) cable installation, overhead transmission, and other installation methods. The team identified the overhead option as the lowest cost, lowest environmental impact, and lowest risk option for BGE.
Navigating Significant Challenges
The project is in an industrial area surrounded by landfills, superfund sites, shipwrecks, contaminated soils, an active shipping pier and shipping channel, and the Francis Scott Key Bridge. The existing 230 kV pipe-type cables must remain in service while the new circuits are constructed. By conveying critical project information early in the design and permitting process to all stakeholders, any issues that may arise during permitting may be addressed proactively.
Protecting the Natural Environment
The stakes are high for the environment surrounding the project, and Century makes its preservation a priority. From delineation and location of specimen trees, streams, and wetlands to coordination with the Chesapeake Bay Critical Area Commission for approval to alter areas within 1,000 feet of the tidal waters, our team is dedicated to making environmentally friendly and sustainable design decisions.
