GridLAB-DTM is an open source project initiated by the US Department of Energy Office of Electricity Delivery & Energy Reliability. Although it was started at Pacific Northwest National Laboratory for the US DOE, participation in this project is open to all interested parties at no cost. If you have proprietary products that you would like to connect to GridLAB-D, you may do so at no cost. However, GridLAB-D itself is not distributed with any proprietary components.
The License under which GridLAB-D is distributed is a BSD-style license. This means that distribution is unrestricted, provided basic common sense and decency is used. Specifically:
In addition, the license stipulates that the software is provided "as-is", it is not warranted to be appropriate for any particular use, and all users agree not to hold the US government or any of the contributors responsible for anything that happens as a consequence of using it.
