Tender description

ESB will be issuing a RFQ to suitably qualified tenderers for the replacement of electronic governors in Arndacrusha generating station. The successful contractor shall be responsible for the complete design, manufacture, supply, installation and commissioning of new digital governor controllers. There will be 4 governors required in total. The new governor controllers will be a direct replacement for the existing governors controllers. The current Ardnacrusha electronic governors which were installed in the 1990’s are now approaching the end of their life. Following many years of reliable service, now is seen as an ideal time to replace the existing electronic governor system and to upgrade, only where necessary, the instrumentation and cabling associated with the governor control system. ESB will be issuing a RFQ to suitably qualified tenderers for the replacement of these governors. The successful contractor shall be responsible for the complete design, manufacture, supply, installation and commissioning of new digital governor controllers. There will be 4 governors required in total. The new governor controllers will be a direct replacement for the existing governors controllers. It is envisaged that the replacement governor controllers will interface with the existing hydraulic control valves, inputs/outputs and protection devices with minimal changes only where necessary. The existing mechanical components are being retained. In so much as possible, the 4 separate governors shall be interchangeable with a common set of spares shared between them.
