System Studies & Planning


TRC offers power system planning and studies for transmission distribution and industrial power systems. We understand your complex local and regional electrical grid and internal plant issues, and provide assistance and training in power system relaying, conceptual design and operation.


Distributed generation, renewables, and evolving regulatory, environmental and system security requirements are changing the utility landscape, adding a new level of complexity for your utility system operations. TRC can help.

We give you the information you need to make informed decisions about your power system. We perform power delivery system planning analyses and system impact studies for a variety of customers, including investor-owned utilities, merchant power plant developers, independent system operators and commercial/industrial facilities. We specialize in system planning reliability assessment work in the areas of steady state, dynamic and short circuit studies for all voltage levels of power delivery, including load and generation additions. Our staff of well-qualified and experienced engineers are knowledgeable users of PSS/E, PSLF, MUST, ASPEN, SKM, MilSoft, PSCAD, CYME and other software tools used for delivery system analyses.
