BESS Stations
Chimax has successfully completed detailed engineering design for multiple Battery Energy Storage System (BESS) stations across Ontario. Our experience includes the design of BESS facilities and associated balance of plant systems for projects ranging in capacity from 2 MW to 150 MW. In addition to detailed design, Chimax has supported developers through feasibility studies, preliminary engineering, and cost estimation for a variety of BESS projects, enabling informed decision-making at early project stages. Currently, Chimax is engaged in the detailed design of several BESS substations, including projects at 230/34.5 kV and 44 kV voltage levels, further demonstrating our capability in delivering complex, utility-scale energy infrastructure.
Yukon Energy Corporation’s transmission line
Chimax has established a strong presence in the Yukon through its ongoing work with Yukon Energy under a Master Service Agreement. The firm has completed several transmission line projects, including the detailed design of a 180 km, 138 kV line serving remote communities. Chimax continues to support Yukon’s transmission and distribution network through ongoing engineering services, reflecting its commitment to reliable infrastructure in challenging and remote environments.
Winchester West Distribution Station
Chimax is providing comprehensive detailed engineering services to Elexicon Energy for the design and development of the Winchester West 44 kV distribution station. Prior to detailed design, Chimax also completed the feasibility study, preliminary engineering, and environmental assessment for the Winchester West 44 kV distribution station for Elexicon Energy.
OPG SMR 500 kV Transmission Line
Chimax is supporting the development of critical transmission infrastructure by providing detailed design for a double-circuit 500 kV transmission line linking the SMR station at the Ontario Power Generation Darlington site to a Hydro One station. The project incorporates lattice steel structures, for which Chimax is undertaking full structural design in addition to the detailed line design.
Hydro One Station
Chimax has provided detailed engineering services for several Hydro One transmission station over the years as an engineering partner to the EPC team. Previously Chimax completed the detailed design of 230 kV Guelph Cedar new greenfield station and refurbishment to the existing station, Aylmer Station, Overbrook Substation, SMR I and II Substation. Currently Chimax is working on the detailed design of two 500 kV substations, transmission lines and distribution lines connected to the substations.
Transmission Line Design for NB Power
Chimax continues to support NB Power through the detailed design of two (2) 138 kV transmission lines. As a trusted partner under a Master Service Agreement (MSA), Chimax has completed multiple transmission line projects for NB Power, reinforcing its experience and consistency in delivering high-quality engineering services.
Distribution Station
Chimax has completed number of distribution stations design for several distribution utilities all over Ontario. We completed stations design for Toronto Hydro, Inn Power, Elexicon Energy, Oakville Hydro and Sudbury Hydro. Currently we are providing comprehensive detailed engineering services to Elexicon Energy for the design and development of the Winchester West 44 kV distribution station. Prior to detailed design, Chimax also completed the feasibility study, preliminary engineering, and environmental assessment for the Winchester West 44 kV distribution station for Elexicon Energy.
Transmission Line and Collector System Design for Renewable Projects
Chimax has completed detailed transmission line design for several renewable projects connecting the project substations to the provincial transmission grid. Over the years, Chimax has completed detailed design of over 2,500 km of transmission lines connecting wind and solar projects to the transmission system. Currently Chimax is supporting the development of renewable energy infrastructure in Nova Scotia by providing detailed design services for a 230 kV transmission line and a 34.5 kV overhead collector line serving 22 wind turbines. Working directly with the project developer, Chimax is undertaking the full detailed engineering design for both line systems to facilitate efficient power collection and transmission.
115 kV and 230 kV Transmission Line design for PUC in Sault Ste. Marrie
Chimax has successfully delivered feasibility study, preliminary engineering, and detailed design for two transmission lines (115 kV and 230 kV) in Sault Ste. Marie. These new lines are critical to supporting the expansion of Algoma Steel’s facility, enabling the company to significantly increase its steelmaking capacity and enhance operational efficiency.
Utility Transmission Stations
Chimax has provided substation design for major Canadian utilities throughout Canada. In Ontario Chimax worked for several stations design for Hydro One and outside Ontario, we worked for detailed station design for many transmission utilities and lines connected to stations owned by transmission utilities. Currently we are working on a detailed station design (civil and structural design) for a 230 kV station owned by PUC Transmission in Sault Ste. Marrie.
Local Utility distribution line design
Chimax has established strong working relationships with utilities across the Greater Toronto Area through multiple Master Service Agreements. The firm has delivered, and continues to support, a diverse portfolio of overhead and underground distribution line design projects, including infrastructure refurbishments, new builds for industrial customers, and network expansions to accommodate growing residential developments.
Industrial and Mining Substation
Chimax has extensive experience in the engineering and design of substations for industrial and mining applications, delivering reliable and robust solutions tailored to demanding operating environments. Our expertise spans medium- and high-voltage substations supporting a wide range of industrial facilities, including manufacturing plants, processing facilities, and mining operations. Chimax has provided substation engineering services for several major industrial clients, including Algoma Steel, Gerdau industrial facilities, Stelco Hamilton Works, Moose River Gold Mine, Lalor Mine and Vale mining operations. These projects demonstrate our capability to design and deliver complex, transmission-connected substations that meet stringent industrial performance and reliability requirements. All substations engineered by Chimax for industrial and mining clients are transmission-connected, typically operating at primary voltage levels ranging from 230 kV to 115 kV. Our designs incorporate high reliability, operational flexibility, and provisions for future expansion to support continuous and critical industrial operations.
Transmission Station for Renewable Energy
Chimax has strong experience in the engineering and design of transmission stations supporting renewable energy projects, delivering efficient and reliable solutions for grid integration. Our portfolio includes substations associated with solar, wind, and hydroelectric projects, all designed to meet utility requirements and evolving grid demands.
