Task 25/63 joint article on net-zero pathways has been published

Persistent challenges on net-zero pathways are related to renewable energy integration, long-duration flexibility, system adequacy, and grid stability

This IEA Wind Task 25/63 collaboration article presents a comprehensive global review of national and regional modelling practices for net zero emission electricity and energy systems. The analysis highlights significant differences in assumptions, time horizons, technology portfolios, and the treatment of grid reliability, flexibility, and seasonal balancing.

The review concludes that integrated planning across sectors, detailed operational modelling, coordinated infrastructure investment, medium- to seasonal-scale flexibility, and context-specific policy design are essential to ensure that net zero pathways are technically feasible in real world power systems.
