for nuclear energy. Controversy Maryland began to deregulate electricity in the early 2000s (prior to Shattuck's tenure at Constellation) which would ultimately lift the state's electricity rate price caps. This development coincided with large hurricanes in the southeastern United States reducing natural gas production in 2007. All of this resulted in Baltimore Gas and Electric Company, a regulated utility company subsidiary of Constellation Energy Group, having to raise electricity rates by 72%. Opponents argued that increased revenues from Constellation profits should be used to subsidize utility prices and keep them low. Shattuck himself was scrutinized for contributing $8,000 in the Maryland gubernatorial election. On the other hand, defenders point out that BG&E is legally separated from Constellation and is heavily regulated by the state's Public Service Commission to keep levels of profitability in check. The Maryland General Assembly ultimately put up a temporary measure to limit price increases to 15%. Other affiliations In 1997, Mayo Shattuck was made trustee of the Seagram Company, Ltd. Shattuck also serves as an independent director at several corporations including: Capital One Gap Alarm.com Previously, he served as co-chairman of the Center for Strategic and International Studies Commission on Nuclear Policy in the United States. Philanthropy During and after his tenure as the head of Alex. Brown & Sons, Shattuck served as the president of the Alex. Brown & Sons Charitable Foundation. Alongside seven other trustees, Shattuck managed the endowment and gave donations to institutions in the Baltimore area. Notable among these activities were million dollar grants given to the Baltimore Museum of Art, the Baltimore Zoo, and Johns Hopkins Hospital (alongside other similar Baltimore institutions). Since joining Constellation Energy in 2001, Shattuck focused much of his philanthropy on Johns Hopkins University (JHU). In 2004, he was elected to the board of trustees of Johns Hopkins Medicine. In 2007, he donated $1 million to a new burn unit in the Children's Center at the Johns Hopkins University Hospital. Resulting from this donation, the hospital will construct The Shattuck Family Pediatric Burn Unit, which consists of 205 private treatment rooms. In addition to the rooms for patient care, the burn unit will include facilities used for education of students, fellows, and residents at The Johns Hopkins Hospital. Presently, he serves as co-chair of the JHU Capital Campaign. Shattuck has played a large part in leading this effort to raise funds from donors to support the academic
