The Union for the Co-ordination of Transmission of Electricity
coordinated the operation and development of the electricity
transmission grid for the Continental European synchronously operated
transmission grid, thus providing a reliable platform to all
participants of the Internal Electricity Market and beyond.
Since 1951, the Union for the Coordination of Production and
Transmission of Electricity (UCPTE) had coordinated synchronous
operations through meetings of experts and managers from at first a
small number of interconnected companies at the interface of
Switzerland, France and Germany, and over various stages from a growing
number of companies and countries. The UCPTE's operational and planning
recommendations helped ensure reliable supply of electricity in
In 1999, UCTE re-defined itself as an association of
TSOs in the context of the Internal Energy Market. Building on its
experience with recommendations, UCTE turned to make its technical
standards more binding through the Operation Handbook and the
Multi-Lateral Agreement between its members. These standards became
indispensable for the reliable international operation of the high
voltage grids which are all working at one "heart beat": the 50 Hz UCTE
frequency related to the nominal balance between generation and the electricity demand of some 500 million people in one of the biggest electrical synchronous interconnections worldwide.
In its final year of existence, UCTE represented 29 transmission system operators of 24 countries in continental Europe.
On 1 July 2009 UCTE was wound up. All operational tasks were transferred to ENTSO-E.

UCPTE/UCTE The 50 Year Success Story – Evolution of a European Interconnected Grid gives a chronological account on the development of the interconnected electricity grid of Continental Europe and provides facts and figures on the work of UCPTE and UCTE until their transition into ENTSO-E, in July 2009.
