Foreword

Renewable energy generation is part of a broader energy system that relies on specific infrastructure to ensure energy flows efficiently from generation to consumption. Shifting to renewables demands urgent attention to this system, requiring us to rethink how we operate transmission and distribution infrastructure, manage flexibility and storage, and link the power sector with end-use sectors like transport and heating.

We must address these issues to accelerate the deployment of crucial infrastructure and technologies, secure investment, resolve existing and future bottlenecks and plan energy infrastructure to avoid resource overuse and environmental impacts. Doing so will ensure the system meets citizens' energy needs, increasing societal support for the transition.

Addressing misinformation about renewables-based power grids' ability to ensure a 24/7 electricity supply is equally important. Integrating high shares of renewables in power grids is possible, and technical solutions exist. Several countries have reached 100% renewables in the daily operation of their electricity systems, and 12 countries have successfully integrated up to 67% of variable renewables on a yearly average. However, achieving this requires forward thinking, political vision, integrated planning and substantial upfront investments.

This fourth module of the Global Status Report 2024 – Energy Systems and Infrastructure – covers recent trends and developments in policies, deployment and technological advances related to grid capacity and stability, curtailment of renewables, regional interconnections, energy storage, demand-side management and sector coupling.

As we celebrate recent commitments to renewable energy deployment and assess the road ahead, we must ensure durable policy frameworks and unlock the necessary investments. Recognising the central role of energy infrastructure and integrated cross-sectoral planning while tracking global and regional developments is crucial.

I want to thank the REN21 team, authors, special advisers, contributors and the entire REN21 community for their expertise and time in producing this module. I trust that this module will provide the insights needed to empower policymakers, industry leaders and stakeholders to fast-track the energy transition with renewables.

Sincerely,

Rana Adib
