ESB National Grid Signs Contract for EMS

ESB National Grid, Ireland’s transmission system operator, has signed a contract with ALSTOM to provide a full replacement for ESB National Grid’s existing energy management system (EMS). The project represents the first ALSTOM EMS to be deployed in Europe that will utilize a full Microsoft Windows 2000 solution.

In addition to managing the transmission system, ESB National Grid is responsible for the operation of Ireland’s power market, which is being deregulated in accordance with European Union liberalization directives. The new ALSTOM system is designed to facilitate the integration of existing and future market requirements.

ESB National Grid’s new system will include:

  • A National Control Centre (NCC) responsible for all normal supervisory control and data acquisition (SCADA) and EMS functions,
  • An Emergency Control Centre (ECC), which is an exact replica of the NCC and takes over all SCADA/EMS functions in the event of serious disruption to NCC operation; and
  • A Dispatcher Training Simulator (DTS), which is separate from but connected to the NCC and facilitates dispatcher training.

The system will be based on ALSTOM’s core e-terraplatform set of standard software applications that form the foundation for generation, transmission and distribution of electrical energy.
