The number of members approaching 100, seven international standards and 50 certified implementations are strong evidences of market acceptance worldwide.

1997 - The Association is founded on 31 March 2007 and the first General Meeting is held on 15 October. Technical work starts based on DLMS – IEC 61334-4-41 – to develop the COSEM object model and a communication profile for PSTN.

1998: The first Blue Book and Green Book are released and the website is launched.

1999: The OBIS identification system is published as the Orange Book and work on conformance testing starts.

2000: The revised Books are introduced to IEC and CEN for international standardisation. The website and the Statuses are adapted to growing membership.
