Power Generation

Doherty Engineering Inc. provides comprehensive consultancy services to Property Managers/Facility Operators, Utilities, Architects, Builders, Developers and Industrial Facilities over the entire project life cycle. Our expertise encompasses the design, and the development through to implementation of new projects, engineering and technical review. Additionally, we have the knowledge and experience to conduct full environmental impact assessments (EIAs) as required in determining the feasibility of potential projects. Our power generation projects range from micro- generation to several hundred megawatts.

Expertise at DEI begins with front end commercialization services at the early development phases of a project. We build financial models, rate structures and energy services agreements for thermal energy contracting and are intimately familiar with power purchase agreements and funding approaches to generation projects in Ontario.

Our success in developing and delivering power generation projects is internationally renowned using a variety of prime movers. These include conventional thermal generation utilizing gas and oil, to renewable applications utilising hydro, solar and biomass. Our cogeneration plant designs have included gas turbines, reciprocating engines, hydraulic turbines and steam turbines. Our designs also implement environmental enhancements that consistently exceeded the code requirements, providing clients with substantial energy cost savings on every project.
