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)
…for renewable energy in the overall energy mix to 42.5% (with the ambition of 45%) – up from 40% in the 2021 proposal. Achieving this will require more than 1 200 gigawatts (GW) of installed cumulative renewable power capacity by 2030, almost double that of 2023.The key barrier to rapid renewables deployment in many EU Member states is lengthy and complex administrative procedures related to project permitting. In May 2022, the European Commission released recommendations on permitting, including on identification of renewable acceleration areas (RAAs) where shortened and simplified permitting can be applied.In November 2023, the revised Renewable Energy Directive…

Powering Ireland’s Energy Future
…this transition, supported by a detailed security study on the electricity supply mix.The analysis sets out five pillars for policy action: Establishing a cross-sectoral energy security strategy for the 2030s; delivering the enabling infrastructure to accommodate the growth of electricity demand and supply; accelerating the delivery of generation capacity, storage and demand-side flexibility; enabling secure system operation under high renewable penetration; advancing workforce skills, strengthening partnerships and facilitating electrification. Ireland can build on its progress in power system transformation to set an example of secure integration of large shares of variable renewable generation while safeguarding energy security.

Brazil 2025
…Review was prepared in partnership between the Government of Brazil and the IEA. It draws on the IEA’s extensive knowledge and the inputs of expert peers from IEA Member countries to assess Brazil’s most pressing energy sector challenges and provide recommendations on how to address them, backed by international best practices. The report also highlights areas where Brazil’s leadership can serve as an example in promoting secure and clean energy transitions. It also promotes the exchange of best practices among countries to foster learning, build consensus and strengthen political will for a sustainable and affordable energy future.
