ESB International was contracted by ESB to provide consultancy services on a €500m capital project at the 915 MW coal fired Moneypoint power station. The Moneypoint Environmental Retrofit Project (MERP) was required to reduce emissions of NOx and SOx particulate matter in line with ESB commitments and in compliance with EU Directives, and to extend the life of the plant. Moneypoint is Ireland’s largest power station and consists of three 305 MW steam generating boilers. It is capable of generating up to 915 MW of electricity, approximately 20% of electricity demand in the Republic of Ireland. The project required the erection and commissioning of Selective Catalytic Reduction (SCR) equipment to reduce NOx (nitrous oxide) emissions and Flue Gas Desulphurisation (FGD) equipment to reduce SOx (sulphurous oxide). It also involved the installation of a new control and instrumentation system and the mid-life refurbishment of the plant. ESB International acted as owner’s engineer for the refurbishment of the plant and installation of the emissions abatement equipment. ESB International also commissioned the installation of the new control and instrumentation system.
The existing control and instrumentation (C&I) systems at Moneypoint were replaced with open system architecture to support the integration of the new emission control equipment and ensure the availability of maintenance support and spare parts into the future.
This project achieved a 71% reduction of SOx, from 32,000 tonnes per year to 9,300 tonnes per year and a 54.5% reduction of NOx, from 22,000 tonnes per year to 12,000 tonnes per year.
ESB International added significant value to the project through:
• An in depth knowledge of changing planning legislation and regulatory arrangements.
• The development of an innovative formal compensation scheme for affected stakeholders, which minimised impact on construction timeframes.
• Very well developed stakeholder relationship management processes.
• A complete in-house project capability from inception all the way through to handover which meant that ESB International was the single point of contact for the client from start to finish of the project.
For this project, ESB International delivered a turnkey carbon capture solution through installation and commissioning of Circulating Fluidised Bed (CFB) and Selective Catalytic Reduction (SCR). A significant investment was made on behalf of ESB by ESB International which amounted to €500m.
One of the most important criteria was the minimising of down time of generators in what was an operating power plant. This project was completed on time and under budget and achieved air emissions below what was originally specified.
