History
The plant was originally owned by PG&E National Energy Group, a subsidiary of PG&E Corporation (whose leading subsidiary is Pacific Gas and Electric Company), who commissioned it in 2001. PG&E National Energy Group filed for Chapter 11 bankruptcy in 2003. After the bankruptcy, Mach Gen LLC was formed to own four of PG&E National Energy Group's power plants including the Millennium Power Plant. MACH is an acronym where each letter represents one of the four initial plants. The M represents the Millennium Power Plant.

In 2014, Mach Gen LLC filed for Chapter 11 bankruptcy leading to its 2015 sale of a portion of its natural gas portfolio including the Millennium Power Plant to Talen Energy.

Environmental Concerns
As of 2012, the Millennium Power Plant was the fourth-largest emitter of greenhouse gases in Massachusetts and produced 924,993 metric tons of greenhouse gases in 2011.
