Modernising Grids in the Age of Electricity

The IEA examines how digital technologies and artificial intelligence can unlock hidden capacity in existing electricity grids as demand accelerates. Rather than waiting years for new lines, operators can use grid-enhancing technologies, dynamic ratings and better data to connect more generation and storage sooner, with the main barriers now institutional rather than technical.

Key Takeaways

Digital deploys faster: Digital sensors and grid-enhancing tools reach service in under three years, versus eight to twelve for new high voltage lines.
Demand outpaces energy: Electricity demand grew roughly twice as fast as overall energy demand over the past decade, and must keep climbing through 2035.
Capacity without reinforcement: Dynamic ratings, topology optimisation and power-flow control could connect up to 330 gigawatts to existing networks without new lines.
