The Niagara Plant Group operates hydroelectric generating stations on the Niagara River and at DeCew Falls in St.Catharines. These stations have a total capacity of 2,278 MW and a full-time staff complement of 231 people.

The plant group's annual production is in the range of 12 billion kilowatt hours, or enough power to supply over one million homes year round.

	Adam Beck I Capacity: 498 MW		Adam Beck II Capacity: 1,499 MW
	DeCew Falls I Capacity: 23 MW		DeCew Falls II Capacity: 144 MW

OPG is currently constructing the Niagara Tunnel which will further increase the output from the Sir Adam Beck complex by 14%.

Between 1996 and 2005 OPG completed a major upgrade at the Sir Adam Beck II Generating Station, increasing its potential capacity by 194 megawatts. Water delivered by the Niagara Tunnel will complement the upgrade and greatly increase the efficient use of the power of the Niagara River.
