Powering Ireland’s Energy Future
…while ensuring secure electricity supply to 2035.This report assesses the outlook for Ireland’s energy security to 2035, drawing on international experience and detailed power system modelling developed with EirGrid, Ireland’s transmission system operator. The Adapted Transition Pathway illustrates how climate, energy and socio-economic goals align around the electricity system, potentially doubling demand and requiring faster infrastructure delivery and deployment of renewables. We find that there is a clear need to establish a unified cross-sectoral energy strategy to set a vision that guides this transition, supported by a detailed security study on the electricity supply mix…

Scaling Up Demand Flexibility
From peak management to efficient system operation This report has been developed as part of the International Energy Agency (IEA) Digital Demand-Driven Electricity Networks (3DEN) initiative to examine the growing importance of demand flexibility in electricity systems amid rising demand, increased renewable energy integration and the electrification of power systems. Case studies in chronological order to examine the changing role of demand flexibility over time from South Africa (2025), Thailand (2030) and Ireland (2035) demonstrate how demand flexibility improves reliability, reduces costs, supports renewables integration and manages network constraints. To realise these benefits, the report emphasises the role for…

IEA Support to Accelerating Renewable Energy Permitting (ARPE)
Between October 2023 and March 2025, the IEA implemented the “Accelerating Renewable Energy Permitting” (ARPE) action. The goal of ARPE was to support five EU Member states – Finland, Ireland, Lithuania, the Netherlands, and the Slovak Republic (Focus countries) – in developing and implementing policy and regulatory measures aimed at reaching their renewable energy targets, notably through accelerating permitting of renewable energy projects.In support of this objective, the IEA organised and facilitated five workshops focused on the following topics:streamlining administrative proceduresaccelerating offshore wind deploymentfacilitating spatial planning for renewable energy deploymentensuring public engagement and acceptance, and afinal workshop summarizing the project…

Cost of Capital Observatory
Tracking the cost of capital for clean energy projects in emerging and developing economies The Cost of Capital Observatory is an initiative from the IEA, the World Economic Forum, ETH Zurich and Imperial College London. The aim of the Observatory is to increase transparency in the energy sector and inspire investor confidence, especially in emerging and developing countries where data on financing costs is scarcer.The Observatory is divided into three sections:A Dashboard that provides free data on the cost of capital for energy projects in emerging and developing economies, updated with 2023 and 2024 data in July and…
