Mayo A. Shattuck III, who helped sell two Baltimore institutions to out-of-state concerns and ran the region's energy firm for a volatile decade, has retired from the parent company of Baltimore Gas and Electric Co.

Maryland energy regulators approved Constellation Energy Group's sale to Chicago-based Exelon Corp. Friday, but directed the companies to create a $113.5 million fund for customers of Baltimore Gas and Electric that would provide energy efficiency and low-income assistance and to meet other conditions.

Jay Hancock: Maryland's Public Service Commission must make triply sure that the sale of Constellation Energy to Exelon Corp. doesn't put Baltimore Gas & Electric at risk.
