World electricity demand is expected to increase by an average of 3.4% every year until 2026

Electricity, derived from the flow of electric charge, is vital for numerous aspects of modern life, from work and communication to transport and leisure. Most electricity is produced from fossil fuels in power plants, but low-carbon sources like nuclear and renewables (solar, wind, hydro, biomass) are increasingly contributing to the global generation mix. These efforts aim to mitigate climate change and leverage falling technology costs. Electricity generated is fed into a grid, transmitted over long distances, and distributed regionally to homes and businesses.

Balancing electricity supply with demand is complex, requiring markets to ensure sufficient generation through forward contracts and real-time balancing with flexible measures like dispatchable generation, energy storage, and interconnection. The system is evolving with more intermittent renewables and decentralized generation, creating supply-side disruptions and demand-side uncertainties. Future electricity systems will need enhanced grid roles, greater flexibility, and new business models, increasingly relying on digital technologies.
