Part of the facility's property is on the mainland surrounding West Jefferson Avenue in southern Wayne County.

The main building – the two-smokestack power station – and the coal yard are located on what is now technically the southern portion of Slocum's Island in the Detroit River.

The Trenton Channel Power Station and the affiliated Sibley Quarry occupy 458 acres (185 ha) of land along the Detroit River, in which 225 acres (91 ha) of that property is open fields, woods, ponds, and sound berms.

They were also the first power plants in the US to use electrostatic precipitators to capture fly ash from the stacks.

[citation needed] By the mid-1970s, the low side plant was decommissioned and the boiler house was eventually demolished.
