TG Power Generation Maintenance Optimization Network (PGMON)

Diese Seite verfügt über einen geschlossenen Bereich in myVGB. Als Gremienmitglied können Sie sich hier anmelden.

Despite competition between Power Generation Companies, the members of the group believe that there continues to be considerable benefits in adopting a co-operative approach to addressing the problems of the future. These benefits have been expanded over the past 10 years through formal and informal contact and exchange of information and experiences.

The changing energy market, deregulation, competition and concern for the environment are key factors both now and in the future. Considerable emphasis is placed on reduction of 0&M costs and increasing efficiency.

The members of the group have established as their mission:
  • To promote and to facilitate the continuous improvement of overall plant management practices.
This mission to be achieved by working on the identification, evaluation, and improvement of strategies, tools and methodologies in the field of power station maintenance and operation in areas such as:
  • Operations and Maintenance Costs
  • Production capability (Availability and RAM data)
  • Quality
  • Safety
  • Environment
  • Risk Management
The current members of the Group (June 2010) are:
  • EDP (Portugal), EDF (France), Vattenfall & Dong (Denmark), ESB (Ireland), RWEnPower (U.K.), KEMA/NRG (Netherlands), E.ON (U.K.), Electrabel & Laborelec (Belgium), IEC (Israel) and VGB representatives.
