Constellation Energy is a leading supplier of energy products and services to wholesale and retail electric and natural gas customers.
Constellation is a major generator of electricity with a diversified fleet of generating units strategically located throughout the United States, totaling approximately 12,000 megawatts of generating capacity.
The company operates the Baltimore Gas and Electric utility, which provides electricity and natural gas in Central Maryland with 1.2 million electric customers and 640,000 natural gas customers. Baltimore Gas and Electric has served customers since 1816.
Headquarters of Constellation are in Baltimore with offices in North America, Europe, Asia and Australia.
The company reported 2010 revenues of $14.3 billion with net loss of $931.8 million.
"We ended 2010 having completed all of the strategic initiatives we announced at the start of the year, successfully putting our core businesses in a stronger position to operate more efficiently, strengthen existing customer relationships and win new business," said Mayo Shattuck, chairman, president and chief executive officer of Constellation Energy. "We completed our goal of deploying more than $1 billion of cash to acquire strategically located generation assets, including the 2,950-megawatt Boston Generating fleet in New England and the 550-megawatt Colorado Bend Energy Center near Wharton, Texas. Through acquisitions and organic growth, we significantly increased our generation capacity during the year, laying the foundation for continued growth in our wholesale and retail energy supply businesses in regions where our load obligations exceed our physical generating capacity.
The company's origin dates back to 1816 when artist and entrepreneur Rembrandt Peale burned gas to illuminate his Baltimore City salon. His so-called "ring beset with gems of light" became the seed that grew into the Baltimore Gas and Electric's (BGE) predecessor, the Gas Light Company of Baltimore.
On April 30, 1999, Constellation Energy Group, Inc., became the holding company for BGE and Constellation Enterprises, which included Constellation Energy Source, Inc., Constellation Investments, Inc., BGE Home Products & Services, Inc., Constellation Power Source, Inc., Constellation Power, Inc., and Constellation Senior Services, Inc.
