When built, the Bridge Mill Plant generated electricity via water and/or steam power. The red brick flat-roofed building rises three stories at its highest points and is comprised of three principal sections -- the gatehouse, powerhouse, and boiler house. The small, north block of the building contains the gates and hoists required to control the flow of water into the powerhouse, located in the central portion of the building and where five pairs of 33-inch turbines once operated. dominate the central portion. Meanwhile, steam engines located in the boiler room served as a backup for providing energy to the turbines during the dry season.
In the mid-1880s, members of the Goff family of Pawtucket began buying up the various small lots and the much-divided water privileges on the western side of Pawtucket Falls with the intention of developing a grand commercial and manufacturing district. Thus, the Goff family required the construction of a plant able to generate power to a host of industrial buildings. However, the plant appears to have been the only piece of the Goff's broader plan to have come to fruition. Shortly after the plant's completion, the Goff-owned Bridge Mill Power Company merged into the Pawtucket Electric Lighting Company (owned by the Pawtucket Gas Company) to form the new Pawtucket Electric Company.
