On June 5th, 2025 France experienced a special event of the power system. Despite being a normal working day, the day-ahead market recorded electricity prices in France equal to zero or slightly negative for a full row of 17 consecutive hours, marking an unprecedented record for the duration of this phenomenon, which signals a production surplus.

This ERRA report examines how energy regulators evaluate grid investment plans and implement incentives to ensure efficient and timely introduction of critical electricity infrastructures. Building on previous ERRA EMER Committee work, and on a deep survey of 13 ERRA regulators, it provides a comprehensive analysis of regulatory approaches across multiple jurisdictions, both EU and non-EU, offering insights into current practices and emerging trends. Five in-depth case studies are examined in chapter 5.

Phasing out coal is a quite challenging task for energy policy in the modern era. It involves the very particular need to balance technical, financial, social, and regulatory difficulties.

Grid systems that move away from power plants with synchronous spinning turbines need a strategy for addressing the loss of inertia. Better situational awareness can help, as can incentives to encourage the retention and production of inertia. This OIES paper looks at British and Nordic experiences and responses, and outlines what to watch for - so that the coming century, like the last one, is marked by a central role for reliable electric supply.

This report is part of the IEA’s expanding work analysing the deepening ties between energy and AI. It builds on the Global Conference on Energy and AI the IEA hosted in December 2024 – the largest conference on this topic to date – and the Agency’s contributions to the AI Action Summit chaired by France and India in February.

The global energy landscape is evolving, with an increasing focus on sustainability and the transition towards cleaner energy sources.

Grid scarcity in countries characterized by a high phase of renewable energy integration is one of the key barriers for their successful energy transition. As the issue becomes more apparent also among ERRA member countries, the Association issues the Study on how grid scarcity is perceived among ERRA regulators and how the issue can be tackled with the right tools.
