From time to time, unexpected events may necessitate a thorough review of your system, such as the interconnection of a new large load or distributed generation facility, or the addition of a large motor at an existing location. In some cases, existing plans or facilities may be inadequate to properly handle a system impacted by an unexpected event.

A system impact study can provide your utility with an understanding of how a change can affect your system. Power System Engineering, Inc. (PSE) can make recommendations to properly accommodate these changes. PSE can develop a cost estimate of any recommended system modifications to assist the utility with contractual, tariff, and contributions in aid of construction (CIAC) decisions associated with a new large customer or distributed generation interconnection.
