Project Overview
The Maryland Line to High Ridge project involves the construction of approximately 59 miles of new 500kV transmission lines, within the existing BGE right-of-way, stretching from the High Ridge Substation in Howard County to the Maryland/Pennsylvania State Line north of the Graceton Substation in Harford County.
This work also requires the rebuilding of approximately 34 circuit miles of the existing 500kV transmission line and about 19 circuit miles of the existing 230kV transmission line. The 500kV transmission lines will utilize lattice tower structures and tubular steel pole monopoles, while the 230kV transmission lines will consist of double circuit steel monopoles on concrete foundations. This work is divided into ten sections, which include the demolition, modification, and reconstruction of transmission lines and circuit poles. Construction is expected to begin in 2027.
Right-of-Way Elevations
The elevation drawings below represent the typical conditions of the right-of-way for each segment of the project. Final design is subject to change pending public, engineering, and
regulatory review.
Permitting
One of the permits required for the Maryland Line to High Ridge Project is called a Certificate of Public Convenience and Necessity (CPCN). BGE has recently submitted its CPCN application with the Maryland Public Service Commission (PSC), a state agency that regulates public utilities like BGE, which the PSC has docketed as Case No. 9884. BGE’s CPCN application includes extensive information related to the Project and is available to you electronically on the PSC’s website at: https://webpscxb.pscmaryland.com/DMS/case/9884.
Hard copies of the CPCN application will also be available for reviewing at the following public libraries:
- Baltimore County Public Library Ownings Mills Branch, 10302 Grand Central Ave., Ownings Mills, MD 21117
- Baltimore County Public Library Hereford Branch,16940 York Rd., Hereford, MD 21111
- Harford County Public Library Norrisville Branch, 5310 Norrisville Rd., White Hall, MD 21161
- Howard County Public Library System Central Branch, 10375 Little Patuxent Parkway, Columbia, MD 21044
- Howard County Public Library System Savage Branch, 9525 Durness Lane, Laurel, MD 20723
The PSC provides opportunities for public comments in the CPCN process, as well as the opportunity to seek to intervene as party in the CPCN proceeding. The PSC has set Monday, August 3, 2026, as the deadline for persons to file petitions to intervene in this case.
Petitions to intervene in the matter must be filed with the Commission’s Executive Secretary, Andrew S. Johnston, Maryland Public Service Commission, William Donald Schaefer Tower, 16th Floor, 6 St. Paul Street, Baltimore, Maryland 21202, and must reference “Case No. 9884”. Petitions to intervene may be mailed or e-filed. Details of the e-File system can be found on the Commission’s website. Interventions are governed by Annotated Code of Maryland, Public Utilities Article (“PUA”) § 3-106. Information regarding the CPCN process and intervention can be viewed on the Commission’s website at: https://psc.maryland.gov/regulated-utilities/electricity/cpcn/. You may reach out to the PSC directly for further information about the CPCN process using the contact information provided on their website.
