Maryland senators are questioning the process energy companies follow to get supplemental transmission projects approved, amid growing constituent pressure over rising energy bills. The scrutiny comes after a project in Port Covington ballooned from $100 million to $500 million in just six years. Most rate increases in the state are approved by the Public Service Commission, a state agency. Supplemental transmission projects, like the one in Port Covington, are approved federally. Baltimore Gas and Electric says the process is robust and transparent. #LocalNews #Maryland #news #energybills
