ATP licensing conditions



EMTP was developed in the public domain at BPA (the Bonneville Power Administration) prior to the commercial initiative in 1984 by DCG (the EMTP Development Coordination Group, with which BPA has had no connection since expiration of the associated agreement on the last day of 1987) and EPRI (the Electric Power Research Institute of Palo Alto, California, USA).

Whereas BPA work on EMTP remains in the public domain by U.S. law (FOIA, the Freedom of Information Act), ATP is not in the public domain. It is, however, available free of all charge to anyone in the world who has not participated voluntarily in the sale or attempted sale of any electromagnetic transients program (hereafter called "EMTP commerce").

Licensing to use ATP is free of all charge for all who have not engaged in EMTP commerce. Once one is licensed, he is authorized to obtain ATP materials from anyone (sharing among users is encouraged). In general, organizational licensing is preferred over licensing of individuals. Some user groups such as EEUG and JAUG accept only organizational licensing. Self-employed consultants are treated as entities. Undergraduate students are not licensed personally, i.e. they should be supervised by professors and lecturers at universities. For any particular case, please contact the user group. Application for a new ATP license will be necessary, if a licensed user moves to another company or his/her address changes.

Follow these steps for licensing:
