| 摘要： | One of Maryland's largest electric utility providers, Baltimore Gas and Electric (BCE) owns and operates a high-voltage transmission grid. Most of BGE's 230-kV lines circling Baltimore are aboveground; however, at the Key Bridge, the utility has underwater lines, which were put into the riverbed in the 1970s. The 2.5-mile-long portion of the line that crosses the Patapsco River through the main shipping channel is located approximately 10 to 15 ft below the riverbed. Having been in service for over 50 years, this portion displayed signs of deterioration. Given that this section was critical for the resiliency of the grid system, BGE planned to replace it with a new transmission line crossing. Various alternatives were analyzed, with due consideration given to cost, design complexity, environmental impact, stakeholder preferences, permitting complications, and interruption of shipping. In 2015, the project team selected overhead lines incorporating tall towers in the river as the preferred solution, and final design was completed by the end of 2019. |
