Electricity networks are becoming more complex as power flows from a growing variety of generation sources and demand changes across industries, cities and transportation. Transmission and distribution systems must accommodate renewable generation, distributed energy resources and increasingly dynamic electricity consumption. This edition examines the grid technologies supporting that transition, from digital substations and automation to advanced monitoring and interconnections, and explores how electricity networks can become more flexible, visible, reliable and capable of managing a changing power system.

The global energy system is undergoing significant change as electricity demand grows, renewable generation expands and established energy sources continue to evolve. Power plants, grids, oil and gas infrastructure, nuclear facilities and emerging technologies must increasingly operate within a more complex energy landscape. This edition examines the transformation across the complete energy ecosystem, exploring how generation, fuels, networks, storage and technology are reshaping the systems responsible for powering economies, industries and everyday life.

The energy landscape continued to evolve throughout 2026 as renewable capacity expanded, electricity networks modernised and conventional energy industries adapted to changing technological and economic conditions. Storage, nuclear technology, digitalisation and emerging fuels added further dimensions to the transformation. This edition brings together developments across electricity, oil and gas, renewables, grids and energy technology to examine how the sector changed during the year and how different parts of the energy system increasingly influenced one another.

The energy sector enters 2027 with growing electricity requirements, expanding renewable generation and continuing investment across conventional and emerging energy infrastructure. Grids must handle increasingly complex power flows while storage, nuclear energy, natural gas and new fuel technologies contribute different capabilities to the system. This edition examines the energy landscape at the beginning of the year, connecting generation, fuels, infrastructure and technology to understand how reliable and affordable energy can support expanding economic and industrial activity.

Reliable energy supply depends on far more than generating enough electricity. Power systems must respond to changing demand, equipment failures, weather events and variations in generation while maintaining stable operation across interconnected networks. This edition examines the technologies and infrastructure supporting energy reliability, including generation adequacy, transmission resilience, storage, backup systems and grid management. It explores how redundancy, monitoring and better system planning can strengthen the ability of electricity networks to withstand disruption and recover quickly.

Energy storage creates the ability to separate when electricity is generated from when it is consumed. As power systems incorporate more variable generation and increasingly dynamic demand, that capability is becoming more important. Batteries, pumped hydro, thermal systems and emerging long-duration technologies offer different combinations of capacity, duration, response and cost. This edition examines the expanding storage landscape, exploring how different technologies can support grids, renewable integration, industrial facilities and distributed energy systems while addressing very different operational requirements.
