Power System Studies

Evolving regulatory, environmental and system security requirements are changing the utility landscape, adding new levels of complexity for system operators. Timely planning and thoughtful system assessments are critical to managing electrical utility infrastructure.

With an experienced professional staff, TRC provides knowledgeable, in-depth analyses of complex issues related to the electric delivery system and the technical requirements of distribution providers, transmission owners, independent system operators and regional reliability councils. We have experience working with, and within, many operating areas throughout the country, helping us to be able to quickly modify processes and procedures to meet each individual client’s objectives.

TRC has performed more than 600 transmission and distribution planning studies across the United States to analyze the system interconnection impact of wind, solar, storage, combined-cycle gas, biomass fueled, and hydro-electric generators.

Our work includes rigorous assessment designed to ensure that new generation added to a region’s transmission and distribution systems will not have an adverse impact on system reliability and operating characteristics.
