In 2019, Ontario Power Generation (OPG) announced their plan to establish a new corporate headquarters in the Municipality of Clarington and move all their non-station-based positions in Toronto, Niagara, and Durham region here. The new campus will share a site south of Highway 401 with the existing Darlington Energy Complex. Unity Design Studio was hired by OPG to provide design services and perform the compliance design package with CIMA+. The new facility will be a three-storey, net-zero, 200,000 sq. ft. high-tech energy campus that promotes innovation and collaboration for the organization and its business partners. This campus will adopt free-address-workstation model and house 1,250 employees on a given day and more than 1,800 employees on a rotational basis. Unity Design Studio proposed to place the new campus next to Darlington Energy Complex to achieve higher efficiency in infrastructure and mobility which can help OPG achieve their goal of promoting innovation and collaboration within their teams.

Bird Construction with Stantec have been awarded the Engineering, Procurement and Construction contract (EPC, similar to P3) and are currently working through the detailed design with Unity.
