altimore Gas and Electric is asking state regulators to approve a nearly $1.1 billion, 59-mile transmission line running through Baltimore, Howard and Harford counties — a project BGE says is urgently needed after Maryland’s power grid failed a stress test just last weekend, leaving thousands of people without electricity during a holiday heat wave.
The company submitted its Certificate of Public Convenience and Necessity application, a process that permits the construction of high-voltage transmission lines, on June 26 — documentation required for BGE to begin construction.
The new system would carry 500 kilovolts of electricity by connecting the High Ridge substation in Howard County to the Maryland-Pennsylvania state line near the Graceton substation in Harford County. The project also would upgrade BGE’s existing 500-kilovolt transmission line.
