EirGrid’s CP1300 Climate Adaptation Project is a nationwide programme addressing climate risks at substations and along transmission lines in Ireland. The initiative includes capital works flood-resilient infrastrucutre, upgrades of assets’ design standards, and the deployment of dynamic line rating devices.
Highlights
01
Nationwide programme to enhance resilience of substations vulnerable to flooding, and other extreme events such as storms and sea-level rise.
02
Deploying dynamic line rating devices to optimise overhead line performance.
03
Collaborative approach using data from Met Éireann, EPA, OPW, ESB Networks, and others.
Main Information
Ireland’s electricity grid faces risks from pluvial, fluvial, and coastal flooding, as well as storms, strong winds, and dust storms. To prepare for these, EirGrid launched the CP1300 Climate Adaptation Project, focusing on substations most exposed to flooding and other climate hazards. The initiative also incorporates other elements such as deployment of dynamic line rating devices to optimise overhead line performance.
This initiative is part of EirGrid’s wider Network Delivery Portfolio (NDP) — the most ambitious grid development programme in Ireland’s history, covering more than 390 projects that support the country’s Climate Action Plan 2024 and 2030 renewable energy targets. EirGrid follows a six-step framework for grid development that combines technical design, environmental assessment, and public engagement. The CP1300 Climate Adaptation Project is currently in the early design phase, where EirGrid is reviewing technical standards, material selection, and policies to make assets more resilient to the said hazards.
Risk assessments for the project are developed in collaboration with Met Éireann (the Irish National Meteorological Service), the Environmental Protection Agency (EPA), the Office of Public Works (OPW), ESB Networks (responsible for construction and maintenance of the electricity transmission system), and the Department of the Environment, Climate and Communications (DCEE).
