This European Standard was approved by CENELEC on 2004-02-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.

Foreword
The text of document 57/656/FDIS, future edition 1 of IEC 61970-301, prepared by IEC TC 57, Power
systems management and associated information exchange, was submitted to the IEC-CENELEC
parallel vote and was approved by CENELEC as EN 61970-301 on 2004-02-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-02-01
The International Electrotechnical Commission (IEC) and CENELEC draw attention to the fact that it is
claimed that compliance with this document may involve the use of a patent concerning a computer-
based implementation of an object-oriented power system model in a relational database. As such, it
does not conflict with the development of any logical power system model including the Common
Information Model (CIM), where implementation of the model is not defined.
The IEC and CENELEC take no position concerning the evidence, validity and scope of this patent
right.
The holder of this patent right, ICL, has assured the IEC that they are willing to grant a royalty free
license to any entity implementing this standard. This license is issued by default, and vendors wishing
to take up the license are not required to notify ICL. The statement of the holder of this patent right is
registered with the IEC. Information may be obtained from:
ICL

Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights other than those identified above. IEC and CENELEC shall not be held responsible for
identifying any or all such patent rights.
Annex ZA has been added by CENELEC.
