What do you want to do? We can help.

Our Products

PowerWorld's wide range of products provide the tools needed by transmission planners, power marketers, system operators and trainers, educators, and anyone else desiring access to power system information and analysis in a user-friendly format.


Our interactive power systems simulation package for high voltage power systems operation on a time frame ranging from several minutes to several days.


PowerWorld’s system visualization tools combined with real-time data.

Retriever Substation Diagram

A new flexible multi-user operations training platform.

OPS-X Trainer

Utilizes the new time-step simulation feature of Simulator on a simplified PowerWorld platform.


A tool designed to compute characteristic line parameters given the type of conductor and the tower configuration of a three-phase overhead transmission line.


A freeware program designed to make it easy to exchange power flow cases. You can view a solved power flow case graphically using animated one-lines.

Shows the aggregation of data in a one-line diagram by grouping buses in the single graphic object, the substation.

GIC Visualizations with Geographic Data View

July 14, 2015

PowerWorld Simulator’s geographic data view tool is uniquely suited for creating wide-area visualization of geomagnetic induced current (GIC) flow. In this example, substations are denoted by circles, sized proportionally to the GIC in the neutral. The color denotes whether GIC is flowing into or out of the ground at the substation. This simulation incorporates the NERC Benchmark GMD Event […]

New PowerWorld Simulator-Created Images

February 18, 2015

PowerWorld founder Professor Tom Overbye created these rich images in PowerWorld Simulator using a one-line diagram and unified North American power flow models. They demonstrate how Simulator can be used to provide “overview” visualizations, that might be of interest to a wide audience that might include management, media, government, and the general public. The images […]

GMD Vulnerability Assessment and NERC TPL-007-1

February 17, 2015

We recently developed a spreadsheet template for analyzing transformer thermal response due to geomagnetically induced current (GIC), as described in the NERC Transformer Thermal Impact Assessment White Paper. Details for this and for modeling of the NERC Benchmark GMD Event are provided in these knowledge-base articles. We will extend an offer to our North American […]
