ANNAPOLIS, Md. (AP) -- Constellation Energy has agreed to spend more than $340 million to improve water quality at Maryland's Conowingo Dam, which flows into the Susquehanna River and eventually ends up in the Chesapeake Bay, the nation's largest estuary, officials announced Thursday.
The agreement clears the way for the re-licensing and continued operation of the dam's hydroelectric facility on the Susquehanna, which is the largest source of renewable energy in Maryland.
