Modern societies are becoming increasing dependent on reliable and secure electricity supplies to underpin economic growth and community prosperity. This reliance is set to grow as more efficient and less carbon-intensive forms of power are developed and deployed to help decarbonise economies. Maintaining reliable and secure electricity services while seeking to rapidly decarbonise power systems is a key challenge for countries throughout the world.

About electricity

IEA analysis indicates that the large-scale deployment of renewables needed to meet decarbonisation goals is technically feasible. However, the inherent variability of these power sources will lead to less predicable power flows. Greater flexibility of power systems will therefore be needed if large-scale deployment of variable renewable generation, such as solar photovoltaic, wind and tidal energy, is to go ahead without jeopardising electricity security. 

Our focus

Well-functioning electricity markets have a crucial role to play in helping to deliver greater flexibility and to attract the investment needed to achieve decarbonisation and electricity security goals. The IEA Electricity Security Action Plan is a major initiative to help address these challenges. 

Fast facts

  • 40%of energy-related CO2 emissions is from electricity generation
  • 25% - 40% of total electricity supply costs to customers in IEA member countries is due to network services
