In this video, Motley Fool energy analyst Taylor Muckerman takes a look at the recent merger between Exelon (NYSE: EXC) and Constellation Energy. In particular, he talks about the synergies that Exelon is on track to achieve as a result of the merger, synergies that translate directly into huge operation and maintenance savings for the company -- to the tune of $170 million this year, $305 million next year, and $550 million the year after that. Taylor takes us through what the major benefits of the merger were that gave the company these huge savings, and what other positive figures we can expect to see from Exelon in the future as a result.
