Rehabilitation of the Hull 1-Generating Station

Built in early 1900’s, the Hull 1 Generating Station and related water retaining structures had not undergone major upgrades since its original construction.

CIMA+ was the Owner’s Engineer, lead designer and construction manager to undertake the complete rehabilitation of the 12-MW generating station. The goal was to increase its useful life by 50 to 75 years.

CIMA+’s scope of work included the refurbishment of the generating station, intake canal, forebay and tailrace structures, and other related hydraulic structures.

The design also required the removal and replacement of the three existing double camelback turbines, refurbishing the generators, rehabilitation of the powerhouse structure and overhead crane, replacement of all electrical systems, and commissioning of electrical power equipment. Our engineers were also responsible for the design of both upstream and downstream cofferdams.
