Siting and Planning Studies

Prior to holding scoping meetings and initiating the NEPA process, the RUS requires that the Project proponent prepare and submit an Alternative Evaluation (AE) and Macro Corridor Study (MCS) to the RUS. Upon acceptance of these documents by the RUS, scoping meetings can be scheduled.

The purpose of an AE and MCS is to evaluate system level (point A to point B) alternatives that best meet the purpose and need for a project, as well as identify preliminary corridor alternatives.

The AE evaluates the system alternatives that best meet the purpose and need of the project, which is to support renewable energy development and increase electric power reliability. A number of alternatives were studied, including "no action", additional generation capacity and demand side management alternatives.

The MCS is used to identify preliminary corridors that are chosen based on an evaluation of opportunities and constraints gathered from existing land use and environmental data. Preliminary corridors are typically made up of segments that are a minimum of one-mile wide and allow for flexibility in future identification of a preferred and alternative route(s), while minimizing impacts to resources.

In addition to describing the purpose and need for the project, an AE/MCS document describes the corridor identification process in more detail, including a description of identified opportunity and constraints for a project area.
