PLS-Distribution Released!


PLS-Distribution is a streamlined version of PLS-CADD and PLS-POLE designed specifically for the distribution side of the grid. Now distribution organizations can benefit from line design software with the same engineering accuracy that PLS-CADD and PLS-POLE are known for, but in a program tailored specifically to the features and commands typically used on distribution projects. PLS-Distribution uses predefined standards for weather conditions, engineering design criteria, structure framings, and other standards. This allows distribution designers to quickly and easily build structures and line models using the utility's standards without any upfront data entry.

The program is available in two versions: PLS-Distribution which is based on traditional ruling span sag and tension concepts or PLS-Distribution+ which adds the power of our SAPS Finite Element engine for calculating wire sags and tensions.

2019 Advanced Training and User Group Meeting


As has become a tradition, this meeting set a record with 530 attendees from 34 countries. Our thanks to everyone who took time from their schedules to travel to Madison and contribute to the meeting.

Many presentations and handouts from the meeting are available at the ATUG website.

In addition to unveiling Cloud Based Licensing we also showed off our new web site at Our original web site that many of you are familiar with, will continue to serve the PLS Online Library and provide technical support content. Please bear with us as we continue migrating from the old to the new site.

Several requests from the 2019 ATUG round table session have already been incorporated in version 16. For example, "super zoom" is now avoided and the project wizard has a read-only option.
